Bringing back community agriculture services

With food insecurity rising worldwide and nutrition-related illnesses proliferating, countries want to encourage healthier eating. But how can they ensure people are able to buy and prepare diverse, nutritious foods when farmers produce so little of them? National agricultural policies are generally designed to support the cultivation of staple grains such as corn and rice, some oils, and sugar. A recent paper shows that 1/3 of global farms cultivated maize and 1/5 cultivated wheat alone! These foods feed the world amply, and cheaply, but some in the form of highly processed foods.

Another issue is the significant loss and waste of perishable fruits and vegetables, meat and dairy products because of inadequate food storage, poor roads, and people’s lack of access to modes of preserving food for long-term storage. Such inefficiencies along the food supply chain drive up the cost and limit the supply of nutritious, fresh foods in rural and urban areas alike.  In Ethiopia for example, perishable foods such as eggs, dairy, and fish are 8-10 times more expensive than starchy staple calories due to supply constraints.

Turning around such entrenched food systems may seem daunting. But it can be done, beginning at the grass-roots level by improving community-based agriculture extension programs. Extension workers are “door-to-door” or farm-to-farm advisers who translate agriculture science into practical applications for farmers. They help solve problems and provide the training and technology farmers need to improve their operations profitably. Extensionists, as they are called, can also be critical mediators in times of natural disasters or outbreaks of disease among livestock.

A study done in 2014 by the Global Forum for Rural Advisory Services estimated there are 1,059,528 extension agents worldwide, but that could be an underestimate. The range of extension agents in each country varies, with some countries having very few—Barbados has 6—whereas other countries have more—China has 615,000. But, of course, that depends on the number of farmers in the country and how many people each extension agent serves.

Ideally, extensionists can steer farmers toward cultivating more nutritious foods and help them do so profitably. They can guide farmers to save heirloom seeds and improve agronomic practices to produce nutritious crops such as horticulture and raising poultry and goats. They can provide training to farmer families on food preparation and nutrition. They can help farmers adopt cultivation and fertilization practices that protect the environment, limit greenhouse-gas emissions, and help store carbon in the soil. And last, they can advise on post-harvest and storage technologies to minimize food loss on farms.

However, in many countries, they lack the training, tools, transportation, and communication tools to reach farmers. Nutrition training provided to extension agents at agricultural technical schools and universities is ineffective and inadequate, which impedes the ability of agents to identify nutritional needs and provide advice or solutions. They also do not have tools to share with communities nor the training to raise awareness of nutrition as a priority.

In many countries, extensionists also lack the tools that would help them work efficiently with more farmers. For example, in some parts of rural Africa, extension agents do not have mobile phones (or top-ups) to contact farmers about real-time issues like food prices in regional markets or motorbikes to reach far-flung communities. With COVID-19, many extensionists cannot get out to the field, so in places like China and Iran, extensionists are using smartphones and the radio to communicate market information and technical support along with public health safety. Farm Radio International is working with 1,000 stations in Africa to help get out information through extension agents.

It starts at the university level—improving extension curricula in universities or after high-school technical training schools. Investments in refresher certification programs for extension agents are needed in most places globally as technologies change and the latest science and technological know-how on agronomy, nutrition, and climate science tools become available. Continual updates to training modules of extension agents such as the New Extensionist Nutrition Learning Kit developed in Rwanda can strengthen training in nutrition within agriculture. Many local non-governmental organizations can provide this training along with the Food and Agriculture Organization in partnership with Ministries of Agriculture.

Techniques employed by extension agents such as peer-to-peer engagement through model farmers, community champions using a “train-the-trainer” approach, or the “walk-and-talk” methodology, wherein agents interact with client farmers through hands-on demonstrations. One example could be forest walks with farmers. Extension agents could teach farmers how to harvest wild, nutrient-dense foods, followed by demonstrations in preparing and incorporating the food into conventional dishes. The International Fund for Agriculture Development (IFAD) has a program, The Last Mile, which is expected to engage 15,000 extension agents in 18 countries to provide business and market-oriented skills to over 1.5 million smallholder farmers over the next five years. 

Last, women extension agents should be promoted and empowered. Only 15% of extension agents are women, and only 5% of women farmers reap the benefits from extension services. Most extension services have traditionally targeted their resources and interventions towards male farmers. Women extensionists understand the needs and challenges of women farmers, particularly in low- and middle-income countries where 45% of the agriculture workforce is made up of women. They should be invested not only to jumpstart careers but also to support the many women working in food systems that ultimately feed us.

Investing in the people who best understand their communities' needs, be it health or agriculture community workers, is critical to address the challenges that farmers face. However, it won’t be enough to transform global agriculture. Governments, international organizations and the private sector must invest in infrastructure along the entire food supply chain to help farmers grow, store and deliver perishable, nutritious foods. In addition, there is a need to provide farmers the latest climate-smart technologies and tools that would allow them to be resilient when facing natural disasters and other shocks. Insurance and credit are also crucial as safety nets in these uncertain times. That said, face-to-face contact with people exchanging ideas, advice, and knowledge isn’t a bad place to start. So let’s reinvigorate and invest in extensionists.

Can Fixing Dinner Fix the Planet?

Two years ago, I embarked on the writing of my very first book. Coming from a field of expertise that values peer-reviewed scientific publications more than books, I did not think it was in the cards to consider authoring a book about my discipline and my experience working in that discipline. But here we are, and tomorrow, my JHU Press Wavelength series trade book, Can Fixing Dinner Fix the Planet? will be released. The pandemic helped, unfortunately. It nudged me to sit still and put pen to paper.

The book investigates the interactions among food systems, diets, human health, and the climate crisis. It draws on my experiences (along with my team and many colleagues) working and living in Africa, Asia, Europe, and the Americas. It describes how food systems must change to slow and reverse the stark trends we see with increased hunger and obesity, catastrophic climate change, and inequities. The book draws attention to the idea that the very nature of food and food systems can play a significant role in fixing these vexing challenges and bring communities together.

Food books abound—cookbooks by celebrity chefs (thanks Anthony Bourdain!), history of food and cuisines, and self-help diet books. My book does not delve into these areas much. Instead, it delves deep into politics and shows that if we take a “business as usual” path of how food systems have, are, and will operate, there will be significant negative consequences on human and planetary health. It provides examples of what can be done by the various actors like government and food and agriculture industries to promote healthy, sustainable, and equitable diets, sustain the earth’s biodiversity, and protect the environment and all species living on the planet. And last, it raises readers’ food and environmental literacy and empowers readers to take immediate and long-term changes by helping them make informed decisions when they walk into restaurants, grocery stores, farmers' markets, and their kitchens.

The book changed the way I communicate my work. It is not easy to write about a complex topic like food systems and ensure that it inspires eaters, global experts in governments, and those working in and shaping food systems to make better decisions. I tried my best to bring to life some of my experiences working in different countries—from very poor to prosperous—and the experiences of those I have worked with and shared time with in deeply rural and urban pockets of the planet. It provides a nuanced story that takes you away from computer and desk research to farmer’s fields, families’ kitchens, and United Nations’ working forums.

I hope the book shows readers how our everyday diets are the products of massive, interconnected, and highly complex food systems that extend from the seedlings in a farmer’s field to the global distribution and marketing networks that deliver food to our plates. These systems have direct and substantial impacts on poverty, the planet’s natural resources, the nutrition of individuals and populations, the composition of the atmosphere, and social equity. They also are incredibly vulnerable to the climatic changes that we have already seen and that will accelerate in the future.

The lost art of reading a book

I recently did an interview for the Reading List with Phil Treagus. I am a big book fan (my better half is a book publisher and archiver) but especially books on food (go figure). I also have two books coming out this year that I am pretty excited about. The first is through Johns Hopkins University Press titled “Can Fixing Dinner Fix the Planet?” The book is my own take on improving food systems and brings in a lot of my own experiences working on food issues in different places in the world. It comes out May 2021. The second book is a textbook published by Palgrave titled “Global Food Systems, Diets and Nutrition: Linking Science, Economics and Policy.” My colleague Claire Davis and I are excited to see this book out in June 2021.

This is what I had to say about books and you can also go to the original interview here.

How do you describe your occupation?

Educator and researcher of food systems.

Talk us through a typical day for you…

My day starts with a series of very early morning (begins around 5 am) zoom meetings with other researchers and organizations (UN, NGOs, etc.) working in Europe, Africa, and Asia on projects, publications, or initiatives. If I am not teaching a course that semester, I usually have one guest lecture to do and am usually on one or two public panels/webinars/keynote talks throughout the day. I try to block some time to read, write and do data analysis and, of course, to exercise (one hour a day)—usually mid-morning or late afternoon. Sometimes, I have 10-15 meetings throughout the day, so having concentrated focus time is challenging. Dinner is always the highlight of the day. We eat early, like 5:30, and my husband whips up gourmet meals. We usually watch something on Netflix or Criterion for about an hour or so. Then back at it to do a bit of writing in the early evening. I am in bed (and asleep) by 10 pm.

What are you reading at the moment, and what made you want to read it?

Science Fictions: How Fraud, Bias, Negligence, and Hype Undermine the Search for Truth by Stuart Ritchie. With so much dis- and misinformation on facts, data, and evidence, and the significant conflicts of interest in the food world, I was very keen to look inward into the science community that generates information. Where have we failed? Where are our faults? What could we do better? This book highlights the pitfalls of how we develop, communicate and vet science (with nutrition examples throughout the book) and turns the mirror on the science world. It is fantastic!

Can you remember the first book you read by yourself?

It is a toss-up. The two that stand out to me and are forever imprinted on my brain is Mrs. Frisby and the Rats of Nimh by Robert O’Brien and James and the Giant Peach by Roald Dahl. Strangely, and I haven’t thought about this until just now, both involve the food world. Mrs Frisby (a mouse) needs to move her home, which is endangered from the fields’ annual spring plowing. She asks a sophisticated bunch of rats for help. The story of James centers on a boy who enters a peach, and his world changes. Both stories highlight the magic and mysticism of ecosystems and experiences with that magic.

Are you a page folder or a bookmarker?

Page folder. But I go one step further. I fold the top of the current page I am reading so I know where I am the next time I pick up the book. I fold the page’s bottom if there is something on that page I want to go back to or research later.

Can you tell us a little more about the Global Food Security Journal?

The Journal strives to publish evidence-informed strategic views of experts from a wide range of disciplinary perspectives on prospects for ensuring food security, nutrition, and health across food system issues. We wish to publish reviews, perspectives articles, and debates that synthesize, critique and extend findings from the rapidly growing body of original publications on global food security, nutrition, food systems, and related areas; and special issues on critical topics across food security, food systems, and nutrition including how these are impacted by climate and environmental dynamics.

If you could gift yourself books at age 16 and age 25 – what would they be and why?

The Omnivore’s Dilemma: A Natural History of Four Meals by Michael Pollan and The End of Food by Paul Roberts. Pollan has mastered the craft of telling compelling food stories that have political, social and environmental repercussions in such an approachable way. While the book focuses mainly on the United States, it does raise questions as to the sustainability and ethics of how we grow our food and the individual dietary choices we make every day. Pollan has his fair share of critics, but I have yet to see an academic write such a compelling narrative on the fractured global food system. Paul Roberts’s book had an even deeper impact on me. It was hard to eat after reading his book because essentially, you feel the world is doomed! As Jim Morrison of The Doors sang, “the future is certain and the end is always near.” The End of Food, as the title suggests, brings those lyrics to life…

If you could invite 5 authors (dead or alive) to a dinner party – who would they be and why?

Amartya Sen (for his incredible influence on how we view poverty, famine, and human development and his many authored books including Poverty and Famine). Mark Kurlansky (for his incredible journalistic deep dives into things like Salt, Cod and Paper). Leah Penniman (author of Farming While Back and co-owner of Soul Fire Farm. A walking the talk author and entrepreneur!). Rachel Carson (for her landmark book Silent Spring that influenced the entire environmental movement). Joseph Campbell (his vast knowledge on the human experience and author of A Hero with a Thousand Faces). I highly recommend the interviews he had done towards the end of his life with Bill Moyer. After watching that, I wanted to be better at my craft.

What was the last book you purchased, and why did you buy it?

New Climate War by Michael Mann. Michael is a climatologist at Penn State. He is a clear communicator and fantastic science whose work has helped build the evidence on global warming. His new book is all about the politics of inaction on climate. In the food world, and very much tied to climate, we face similar issues of political inertia, interference and power imbalance of powerful industry players and complex scientific messages. Hopefully, I can learn something from Mann’s experience in battling the “merchants of doubt” and how he and others have fought to keep the evidence of climate change on the top of the global agenda.

What is your favourite thing about reading?

The quiet time and the ability to reflect on other’s views, worlds, and perspectives. I also find that I like the feel, experience, and act of reading an actual book as opposed to an e-book or an audiobook.

What’s the best book you’ve read in the last 6 months?

The Fire Next Time by James Baldwin. Written in 1962 but felt like it was written in 2020.

In your Twitter bio you describe yourself as a ‘goat lover’, I have to ask you to elaborate on this…

Goats are just so cool. Resilient, smart, and independent. And did you know they can surf? My husband and I even keep a blog, named “Goat Rodeo.” Speaking of books, there is a great book about goats entitled Goat Song by Brad Kessler who leaves New York City with this partner to go raise Nubian goats in Vermont.

If you could insert yourself into any book, which would you pick and why?

This is a tough one! Maybe Rats: Observations on the History and Habitat of the City’s Most Unwanted Inhabitants by Robert Sullivan. Robert would roam the city streets of New York in the silence and darkness of night observing what rats would feast on, and how they lived their lives. I am disgusted by but fascinated with these resilient little creatures and it would have been fun to spend a year doing this sort of rodential research. Turns out their diets are a lot like humans…they like junk food.

What is the book that you feel has had the single biggest impact on your life? What impact did it have?

This is really a tough one. I want to say Ulysses by James Joyce but that is a total lie. Perhaps Silent Spring by Rachel Carson. As a trained molecular nutritionist, it upended the way I think about food, human health and environmental sustainability. I pulled my head out of the petri dish and have focused much more on their connections and the macro- long view of food systems and how and where they fit into sustainable development.

If you could only own three cookbooks, which would you pick and why?

Anything by Alice Waters but especially The Art of Simple Cooking. She lays out the necessities of cookware, ingredients and basic recipes you need to at least feel like you are cooking organic, wholesome food straight out of the 1970s Berkeley. She also just propels food and cooking to an art form. Bibi’s Kitchen because it highlights the diversity of Africa’s cuisine told through and shared by grandmothers. Salt, Fat, Acid, Heat: Mastering the Elements of Good Cooking by Samin Nosrat. She makes cooking so approachable.

Are there any books you haven’t mentioned that you feel would make your reading list?

I’d also include:

Chronicles by Bob Dylan,
Just Kids by Patti Smith (I am a big fan of music books),
Salt Sugar Fat by Michael Moss,
Blood, Bones and Butter: The Inadvertent Education of a Reluctant Chef by Gabrielle Hamilton,
Food Politics and Soda Politics by Marion Nestle (see our interview with Marion Nestle),
Mass Starvation by Alex De Waal,
One Day I will Write About this Place by Binyavanga Wainaina,
Four Fish by Paul Greenberg,
Sweetness and Power by Sidney Mintz,
The Wizard and the Prophet by Charles Mann,
and The Way we Eat Now by Bee Wilson.

Which book sat on your shelf are you most excited about reading next and why?

The Secret Life of Groceries by Benjamin Lorr. I love the premise of this book. The author takes the reader through the inner workings of the nebulous supermarket that has become the powerhouse influencer on our diets. I am sort of scared though. I have a feeling I am going to never want to set foot in a supermarket again after reading this. Much like how I felt after reading Fast Food Nation by Eric Schlosser. I have yet to eat at McDonald’s (not that I really want to) since reading that book…

In Africa, Covid-19 Threatens to Worsen Hunger

This is a cross-posted blog and originally on Bloomberg Opinion. The original can be read here.

The continent has some unique strengths, but food insecurity is a special vulnerability. 

“It is easy to see the beginnings of things and harder to see the ends,” Joan Didion wrote in “Goodbye to All That.” Her words resonate in the midst of the Covid-19 pandemic, when no one has a clue whether we’re at the beginning, in the middle or near the end. In sub-Saharan Africa, not knowing is especially worrisome because it’s difficult to tell whether the continent’s fragile food supply systems will weather the strain.

 While the continent has made great strides toward economic security over the past several decades, Covid-19 could stymie that progress. Conditions vary greatly from country to country, but many struggles to ensure that their citizens have access to basic essentials: soap to clean hands, potable water and nutritious food to keep immune systems strong. Hunger and food insecurity have not gone away. Twenty-three percent of people in sub-Saharan Africa are undernourished. Because of the global economic fallout from Covid-19, the number of people worldwide facing acute food insecurity could nearly double this year to 265 million, the United Nations World Food Programme estimates, and much of that impact will be felt in Africa.

 At the same time, obesity and noncommunicable diseases (heart disease and diabetes for example) are rising in many low-income countries, Africa included, and both are proving to be serious complications for people infected with Covid-19. Much of the continent is also still dealing with other complex infectious diseases – HIV/AIDS, tuberculosis, malaria, and other neglected tropical illnesses – that will make it more difficult to treat Covid-19 infections.

 As it expands on the continent, Covid-19 will put further stress on already strained health systems – with limited numbers of ventilators and proper beds, minimal personal protective equipment, and, in some places, too few health care workers.

At the same time, food supply chains are starting to falter. Lockdowns in 30 African countries have made it very challenging for farmers to sell their goods in markets or for workers to get to fields. Food assistance is not always making it to those most in need. Many informal markets – the infamous wet or open-air markets, where most Africans shop for food – are closed, further imperiling food insecurity and threatening malnutrition. Reports from the Global Alliance for Improved Nutrition’s offices in Nigeria and Mozambique noted that prices of food, particularly the fruits and vegetables, have increased significantly.

In many African cities, social distancing and self-isolation are a recipe for disaster. Slums and informal settlements are overcrowded and lack basic services such as running water, cooking facilities, and electricity. And even if people infected with the coronavirus had safe places to isolate, some feel they must work to keep their families fed. Commutes to work often involve overfilled buses and long traffic jams – which increase the spread of disease.

With global unemployment rising, remittances worldwide are also are expected to fall – by 20%, or nearly $110 billion, according to the World Bank. In sub-Saharan Africa, they may drop by 23%. This will push more people to go to work, increasing their exposure.

To be sure, African countries have a few things working in their favor. For one, they have experience with massive infectious diseases – HIV/AIDS, Ebola, and polio, to name a few – and public health systems have been strengthened over the last decade. The Democratic Republic of the Congo has been hard hit by Ebola, but there are signs of progress with a declining case load in early 2020.

 In the current crisis, African governments can take some early lessons from the rest of the world that has been grappling with the pandemic a month or two longer, and work to keep the food supply moving. The continent is still 60% rural, and many urban Africans have close ties to the countryside, owning land or family plots. With luck, lower population density in rural areas may slow the spread of Covid-19, allowing farmers to continue to grow food, that is if they can get access to seeds and the technologies needed to plant and harvest. Support to food producers is an absolute necessity to keep the continent food sufficient.

 Sub-Saharan Africa is also fortunate to have a relatively young population, which may make it better able to weather outbreaks of Covid-19 with less hospitalization and death.

 Still, it remains hard to see the end. Some people hypothesize, with little evidence, that Africa may not be hit as hard as other places because of its warm climate. Perhaps, they say, the spread will be slower in Africa, and that will buy extra time. Given how easily Covid-19 has spread in other warm places such as Singapore and Thailand, that’s not something to count on.

 To ensure that Africa doesn’t starve and that it can weather the Covid-19 storm, it is essential to make sure people are guaranteed access to food, water, soap, masks, and cash transfers to support their families. The poorest and most vulnerable should be the priority. World governments with their donor partners, including the World Bank and the World Food Programme, will be counted on for support over the next four months. Businesses who make food products need support as well. We must all help make sure they come through.

The COVID-19 Crisis and Food Systems: Addressing threats, creating opportunities

Lawrence Haddad, Jess Fanzo, Steve Godfrey, Corinna Hawkes, Saul Morris, and Lynnette Neufeld

With the spread of COVID-19, we find ourselves plunged into a global health crisis. By most accounts, we are only at the early stages of the pandemic so it is going to reshape economy, society, and politics, probably permanently.

Pre-COVID-19 crisis, many families the world over already spent a lot of time and energy thinking about getting access to food. During the crisis, the most vulnerable face the rapid loss of their income - spent mainly on food - and this is an immediate threat that should be prioritized. For many others, simple access to shops has also become very worrying and needs swift attention. Even the wealthy are increasingly thinking about food access at this time.

But are governments, businesses and civil society thinking enough about food access and the wider food system?

How will the crisis shape the food system if we do nothing? And what can we do in the context of the crisis to get the food system in better shape to improve the consumption of nutritious foods for all, especially the most vulnerable?

We desperately need to focus on the operation of food systems at the moment because we know that the quality and quantity of the food we eat is the number one risk factor in the prevention of general mortality and morbidity. If we forget the food system right now, the COVID-19 health crisis will unwittingly use the food system as a catapult to have an even bigger impact on the global burden of disease. If we think and act to change the food system right now, we can reposition it to be more effective at delivering affordable nutritious food during the crisis, and perhaps even after the crisis.

What are the probable effects of COVID-19 (and the efforts to control it) on the food system which shapes our access to nutritious food?

It is difficult to say for sure, but in this table we share some thoughts on the potential impacts throughout the food system of COVID-19 (and the response to it), and some ways of mitigating the impacts. We do this for high- and low-income contexts, which may well exist within the same countries. Many of our suggested actions are responses to immediate needs, but many would have positive impacts well after the crisis is under control.

What are the main threats? We are of course worried about food prices, especially for more nutritious foods, which are already more expensive than staples and unaffordable for many people, especially those on low incomes who already spend much of their money on food. More food staples will be consumed as a result of price hikes, but likely also more, unhealthy, highly processed foods that are cheaper, have longer shelf lives and may provide comfort in tough times. In addition, increased food price volatility (due in part to hoarding and cross border impediments) generates uncertainty and makes it more difficult for food system actors to take all manner of decisions.

We are also deeply worried about negative income shocks on the most vulnerable, through the loss of livelihoods as the demand for certain services collapses and certain production systems are disrupted due to affected workers. Farming, in particular, seems very vulnerable given the older age profile of farmers and the mortality pattern of COVID-19 as well as the sector’s common reliance on mobile workforces. This vulnerability, if realized, will mean less food produced and weaker non-farm rural livelihoods and higher food prices for all, wherever we live. Physical distancing will have an impact on the costs of moving food around, within countries and across borders leading to more food loss and emptier markets. Lapses in food safety, which potentially started all this in a wet food market in Wuhan, will likely exacerbate if no action is taken. 

What are the probable effects of COVID-19 (and the efforts to control it) on the food system which shapes our access to nutritious food?

But there are opportunities. Healthier foods build immune systems throughout life but especially among vulnerable ages, including early life and the elderly, and so there is a window of opportunity to make the case for safe nutritious food. Diabetes and other non-communicable diseases are risk factors for COVID19 mortality and additional attention should be given to preventing the former because of the latter. 

We expect to see food safety move strongly up the policy priority list because of the origins of COVID-19. Social protection programs should be more linked to promoting the consumption and production of nutritious food, not just preventing food insecurity. We expect the prevention of food loss, especially fresh food, during storage and transport to gain a greater profile. The aging of farming capacity will be treated more seriously, with efforts increasing to make farming more profitable and appealing to younger generations.

We can see opportunities for reshaping public sector messaging, not only about hygiene but about nutritious food consumption and preparation. Will there be new opportunities to disrupt food transport by using shared economy models capitalizing on any underutilized haulage capacity to lower costs? Will we see more financing facilities for investing in nutritious food production, processing, storage, distribution and retailing? Will civil society become more organized and active about the provenance of food and about the behavior of businesses and governments in ensuring the provision of affordable food?

Finally, will we see greater collaboration between government and the private sector during the crisis spill over into a reshaped narrative post-crisis about how the two sectors - public and private - can work better together to improve access for all to safe nutritious foods?

This is the first of a series of blogs that we will put out in the coming months. We have asked Nutrition Connect to set up a COVID-19 and food systems site and we would like to encourage our partners, colleagues, friends, and fellow travelers to post blogs, opinion pieces and research reports and papers that are relevant to this topic on the site, with full organizational recognition and lots of cross-posting. 

The COVID-19 health crisis is here. Let’s work together to stop it turning into a food crisis and further exacerbating disease burdens.

Governments, communities, and businesses around the world are showing astonishing energy and innovation to cope with COVID-19. The short-term priority is to stabilize food systems and keep trade open – all people working in food systems from the farmer to the check-out supermarket agent are critical to keep the food system moving. But it is in times of great crisis that fundamental reforms are born. The United Nations, the World Bank, the International Monetary Fund and the advance of the welfare state were developed in the darkest days of the Second World War.

So let’s stand by our neighbors, critical workers, and communities today. Let’s also work to reshape our food systems for tomorrow - to deal with the new COVID-19 crisis as well as the much bigger diet-related health crisis; one that has been with us for decades.

Food bytes: March 21st edition

Food Bytes is a weekly blog post of “nibbles” of information on all things food and nutrition science, policy and culture.

As much as we want to pretend all is normal, it is clearly not. We are in the middle of a global pandemic, with a massive amount of uncertainty, fear, and in some places, complacency. We will be posting another blog entry on the COVID crisis but for now, we will highlight, just a few emerging articles on the growing concern of food insecurity and the food supply, along with our regular updates on all things happening in the food space.

On COVID, we have never been in a situation like this before with talk of it reshaping the global order or social collapse or cohesion. So to predict how markets will continue to react to the future and the health of the global food supply is uncertain. Anyone who postulates how it will go is misleading us. Yes, of course, we can look in real-time on how households and communities are handling the crisis, and we can look to the past, on how other pandemics like the Spanish Flu, impacted food security and supplies. However, times are different. Food supplies are globalized. The population in 1918 was 1.6 billion. We are now at 7.5 billion.

Locusts in east africa (copyright: BBC News)

Rob Vos at IFPRI argues there is no major concern for food insecurity, yet. They came to this conclusion by looking at food prices of staple crops. Huh. As the Brookings Institution rightly pointed out, low-income seniors are already feeling the impacts. In the U.S., with roughly 15% of households being food insecure, some are concerned about their ability to feed themselves in the coming months. A WaPo article quoted: “If coronavirus doesn’t get us, starvation will.” Then there is Africa. Food insecurity and stark hunger could worsen in an already fragile context. East Africa is also reeling from an invasion of locusts which don’t help the already burgeoning food insecurity in the region. This video is pretty insane if you want to see the locust infestation.

The EAT-Lancet Commission report follow ons just keep coming. Did you know that the report has already been cited 790 times since its publication in January 2019? Insane! A few interesting articles are emerging that again test the validity of the Commission’s findings.

The water footprint (blue and green water) of different nut types (shelled) as well as some other food products for comparison, in litre/kg and litre per g of protein. (Vanham et al 2020)

• One article published by the LIvestock Innovation Lab at the University of Florida shows the importance of animal source foods and explains that raising livestock and eating animal source foods can be compatible with sustainable development.

• Another article questioned the recommendation in the report to increase nut consumption. The article dissects the water intensity issues in producing trees and ground nuts especially in India, China, Pakistan, the Middle East, Mediterranean, and the U.S. Check out cashews in the figure!!

• A publication in the Journal of Nutrition argued that the mortality reduction effect of the EAT-Lancet proposed diet in the USA is no greater than the impact of energy consumption changes that would prevent under-weight, over-weight, and obesity alone, calling into question its findings. Authors are funded by the National Cattlemen's Beef Association…

• Pedro Sanchez, one of the world’s experts on tropical soils and a World Food Prize winner wrote a piece about the land needed to grow the Lancet-EAT diet was oversimplified. He provided some alternative calculations. He argues that current total world food production is estimated at 9.30 billion metric tons of crops and animal-sourced foods, with crops grown in 1.27 billion hectares of land. Implementation of the EAT-Lancet diet for 10 billion people by 2050 would require a lot less, 5.39 billion metric tons of food in 1.10 billion hectares of cropland, assuming no increase in crop yields.

Pedro’s paper was part of a special issue in Food Policy in the Food Policy journal initiated by Editor in Chief Chris Barrett. The issue is about the evolution of the Consultative Group on International Agricultural Research (CGIAR), and the international agricultural research centers (IARCs) that comprise the CGIAR System. Over the past two decades, the CGIAR has undergone a series of reforms with the latest reform being termed “One CGIAR”.  Maybe they should take a lesson from the UN and find out how the One UN worked out…The special issue is out and is meant to “help inform a research strategy for the new One CGIAR.”

Robotics, AI, nano. Will these technologies transform the food system, and eliminate the “human” element from agriculture work? Yet to be seen. This article in the Economist discusses agricultural robots. And they have names: Tom, Dick, and Harry.

In the world of nutrition, meat will remain a controversial topic that is heating up. Nutrition is always accused of having serious conflicts of interest - who pays for the research? Who is biased? Who is paid off? JAMA and Scientific American highlights the controversy with meat-funded research and plant-funded research - and the “bullying” by both sides. Katz responds here. The livestock industry responds here. This debate has left consumers confused, and lacking any trust in science. A few other tidbits on meat. This NYT opinion piece by Alicia Wittmeyer argues that to stop eating meat, can alienate us from our traditions. Meanwhile, the EU is considering a tax on meat.

Speaking of diets, with 2.1 billion overweight and obese adults, and half of the U.S. facing obesity, we need some new strategies. Intermittent fasting seems to be all the rage these days as the best way to lose weight and keep it off. A review in JAMA highlights the evidence, and NYT provided some guidance. We tried it. It is not so hard. Just eat between the hours of noon and 8 pm. Thereafter, no calories should be consumed in solid or liquid forms.

Changes in purchases of high-in beverages, by education level of household head (Tallie Smith et al 2020)

Diet quality matters too. Bee Wilson, an amazing writer of food and its history, wrote a long piece in the Guardian on the contributions of ultra-processed foods on the global obesity crisis. These foods are cheap, attractive and convenient, and we eat them every day. But they are also riddled with sugar, salt, and unhealthy fats. This article is worth the read. Some countries are worried. Take Chile. They instituted a Food Labelling and Advertising which put warning labels on the front of food packages if the food was high in sugar, high in salt or high in fat. Sugary drinks, unhealthy snacks, and packaged foods must carry the front-of-pack labels. These foods are also regulated. These foods cannot be marketed or sold in schools or on TV. Has it worked? Yup. Sales of these foods are down 23%. In college-educated consumers, as you can see in the figure, purchases were done 29%!

Have you ever wondered which cuisine the world craves? Turns out, Italy. Yeah, no shit Sherlock. Italy is the largest exporter of their cuisine followed by Japan, Turkey and Mexico — Órale! Who is the largest importer, meaning, their food just sucks? You guessed it Sherlock. America. F!@#%* yah! China and Brazil don’t seem so keen on their local cuisine either. They follow the U.S. on importing other country cuisines. Funny. Brazil’s food based dietary guideline boasts harnessing its local cuisine. We guess people just don’t read those pesky guidelines…

Dari Mozaffarian and Dan Glickman wrote a timely op-ed piece in the New York Times that diets are now the number one risk factor killing Americans, costing the U.S. health care system billions each year. They provide a range of solutions and signify that governments and food and beverage industries need to be held accountable. While unhealthy diets continue to kill so many, politicians completely ignore the issue. As America moves towards what will be a contentious, decisive election year, they suggest that “every candidate should have a food platform, and every [presidential] debate should explore these positions.” Not sure this rhetoric will be high on the Trump “make American great again, for real this time” re-election campaign because the “Potus” just ain’t really that into food. Unless you consider consuming fast food a gourmand type diet.

Another op-ed piece in the New York Times by Catherine Kling urges that producers who cause “nutrient pollution,” in the form of nitrogen and phosphorus coming from agriculture fertilizer and manure run-off, should be required to pay for the cleanup. She suggests that state government regulations should be enforced to ensure that farmers reduce nutrient pollution. Wonder how livestock ranchers feel about that? Gee, take a guess.

IFAD and Bioversity just put out a great guideline on supporting nutrition-sensitive neglected and underutilized species (NUS) and wild edibles (check out Figure 2 particularly). The guideline is led by the great Stefano Padulosi at Bioversity who has some deep experience working on NUS value chains in many parts of the world. He is also the “Rocket Man.” What are NUS you ask? Here is how they define it in the guideline:

Many are the synonyms which have been used since the mid-1980s to refer to NUS, including minor, under-used, under-exploited, under-developed, orphan, promising, lost, alternative, traditional, niche crops, crops of the future, future smart food. In reality, all these terms are often context-specific and loaded with heavy cultural meanings and not easily understood in the same way by everybody. The term “Neglected and Underutilized Species” might not be the ideal expression and may not be appealing to people.

There is so much focus these days on diet and the food system footprints on climate change. It is seriously having its moment. But in the back of our mind’s eye, we hark back to an article published in 2017 in Environmental Research Letters, that indicated that largest impact an individual can make to reduce their greenhouse gas footprint is to have one less child. Check out this graphic to the right. Powerful. This action is followed by living car free. Diet is further down the list of impacts. Food for thought…

Interestingly, they didn’t model reducing food waste by individuals. The World Resources Institute (WRI) has just released a global action agenda on reducing food loss and waste by 2030. It is a really practical guide to setting targets, honing in on who should take action and what scalable interventions are available. Everything WRI puts out is pretty stellar and this is another data rich, practical guide to tackle one of the most important issues of the food system.

What if all Americans ate less meat? Not necessarily eliminating meat completely, but just much less? By the way, American are already slowly and steadily decreasing their beef consumption since the 1980s. In the Nature journal Scientific Reports, scientists tested this idea. By replacing 25% meat with plant alternatives dominated (strangely) by soy, green pepper, squash, buckwheat, and asparagus, Americans can eliminate pastureland use while saving 35–50% of their diet related needs for cropland and 330 million metric tons of greenhouse gas emissions each year, but increase their diet related irrigation needs by 15%.

These advertisements on the left for PETA Vegan guides are all over DC (note the elephant in the background just to remind you that yes, DC is the capitol of the U.S. and the district lives and breathes politics. You can’t get away from it. It will smother, suffocate and slowly destroy you). Where were we? Oh yeah. We picked up the guide and thumbed through it. Some of the recipes didn’t look so tantalizing, and much of what was recommended wasn’t all that healthy. There were lots of photos of faux meat mimicking fried chicken fingers, hotdogs, and meatballs doused in sticky sauce, as well as lots of cakes. Is it possible to promote sustainable, healthy, and animal cruelty free vegan diets for those who choose to go that route PETA? That can’t be too hard can it? While it was an A for effort, maybe version 2 of the guide will feature more healthy foods and less overly processed, junk food.

In other news, with Uber Eats and other gig economy food deliveries on the rise, so is the toll on the drivers delivering food. They are risking their lives in places like South Africa. Tragic. And just to deliver the ultimate convenience to our dinner table.

Venezuela. Talk about a free fall into despair and chaos. Because of the turmoil, food security and the deeper issues of consistent insecurity have taken a big hit. Venezuelans lost an average of twenty-four pounds in body weight. Nine out of ten live in poverty. Roughly one in ten have left the country.

A paper just published in the Lancet hits right at the heart of the trade war between the U.S. and China. The authors feel that it is time to reshape trade policies towards those that favor sustainable food and nutrition systems. They argue there are three starting points for public health actors to take up this agenda.

1. Recognize the fundamental and front-line nature of trade policy as both a barrier and potential catalyst for health.

2. Engage more effectively and with the right stakeholders to push for policy space within trade and investment agreements.

3. Reach beyond trade to promote a development discourse that makes explicit the nutrition imperative — nutrition is crucial to achieving most of the Sustainable Development Goals.

The Food Archive holds a special place in its heart for special focus issues that scientific journals put out. That is, when journals hone in on a hot topic and publish a complementary set of articles on the topic to show different facets and perspectives on the topic.

Here are some recent highlights:

• Tomorrow’s Earth by Science Magazine

• Climate Crisis and Health by New England Journal of Medicine

• Food Security and Violent Conflict by World Development

• Health in Humanitarian Crises by Lancet

• Food for Thought by British Medical Journal

In the last food bytes post, the hard to watch unfold Brazilian Amazon fires were highlighted. This piece highlights that forest fires are happening all over the world, many in biodiverse hotspots, making climate change all that much worse. Very sad not only for forests but for those who live among and depend on them. The map on the right shows fires over the last year. Look at southwest Africa and Southern Africa. Look at Madagascar (think lemurs…) and Southeast Asia. Wah!!

One place prone to massive forest fires (the 2018 fires were the most devastating in the state’s history) is California but every day it finds a way to rub its beauty in our face. Geez, okay Cali, you win.

Speaking of California, and to keep the whole Woodstock vibe going, let’s just end with a little Joni Mitchell, because she sings about omelets and stews and well, because this has to be one of the best albums ever recorded. Click below to hear her beautiful song, California.

California, Joni.

Oh the rogue, the red red rogue
He cooked good omelets and stews
And I might have stayed on with him there
But my heart cried out for you, California
Oh California, I'm coming home
Oh make me feel good rock'n roll band
I'm your biggest fan
California, I'm coming home

Food Bytes is a weekly blog post of “nibbles” of information on all things food and nutrition science, policy and culture.

Took a bit longer to get up the next Food Bytes entry due to summer holidays. So here it goes.

Summer is going out with a roar. The Inter-Panel on Climate Change (IPCC) produced their outstanding report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems. Lots of media coverage followed. Diet recommendations were made (reducing beef, taking on a more flexitarian diet etc). If we want to live in this changed climate, we need to adapt. The saber-toothed tiger had a less flexitarian diet and we know what happened to them…

Speaking of adapting, scientists found a “stature gene” among Central African hunter gatherers, also known as pygmies. This short gene gave them an advantage in Africa’s hot, humid rainforests. I was really hoping this gene hopped across the Atlantic to Italians, or even more so, short Italian American women living in DC to help explain my enduring squat-ness, but alas, no such luck. While on the topic of luck, according to the Union of Concerned Scientists, you should also stay away from cereal that has corn as the main ingredient if you want to have an environmentally friendly diet. So better forget about your Froot Loops and Trix and reach instead for your Lucky Charms.

Let’s continue with the climate onslaught shall we? This article talks about the beginning of the end of the livestock industry. But is that really so? Don’t underestimate the chicken man. And do you know how much of a carbon footprint you consume with your diet? BBC provides a calculator - do the math and you will quickly be blanketed in a quilt of guilt. It ain’t just beef that you gotta worry about…

Sam Myers of Harvard published a great piece in the WaPo on how increased CO2 in the atmosphere will “zap” nutrients from key crops. He argues that 175 million people could become zinc-deficient, 122 million would not be able to get protein, and 0.5 billion would have iron-deficiency-related disease. So now we need to worry not only about getting enough food to feed 10 billion, but the quality of those foods in fulfilling our nutrient needs. And the declines in nutritional quality are happening in real time. A study examining 43 “garden” crops in the U.S. found declines of 6 nutrients - protein, calcium, iron, phosphorous, riboflavin and vitamin C - since 1950. The food supply already can’t keep up. Mario Herrero and colleagues found that our current food supply does not produce enough fruits and vegetables, and in the course of the next 30 years, that supply will worsen. If everyone were to follow the WHO recommendation of 400 g/person/day of fruits and vegetables, 1.9 billion people would not have the access to these foods – the food supply just cannot keep up.

But a recent article in the Global Food Security Journal argues that vegetables hold a lot of economic power. Yeah sure. That is, if we can produce them. And then people want to eat them. They suggest that governments will need to increase their investment in farm productivity including improved varieties, alternatives to chemical pesticides, and the use of protected cultivation. There is also a need for better post-harvest storage of veggies, food safety and market opportunities. To tap the nutritional power of vegetables, consumers need to know how vegetables contribute to health, be able to afford them, or be able to grow them themselves. God speed to those New Yorkers living in 300 square feet of space with no windows and definitely, no outdoor space.

The recent paper by Eker and colleagues, published in Nature Sustainability, adds to the sustainable diet literature and evidence base, examining how consumer diet shifts can contribute to mitigation of climate change. Utilizing scenario assessments, the authors model the impacts of different compositional and behavioral dietary shifts among the global population on environmental footprints. Compositional dietary shifts included average meat consumption, flexitarian (more plant-based), vegetarian, and vegan dietary patterns. As other studies have shown, changes in diet composition towards more plant-based diets, have implications on the environment. However, more significant shifts, by a large swatch of the world’s population, towards vegetarianism would need to occur to see impacts on greenhouse gases and other environmental measures (such as land use). The paper is unique in that it models the behavioral dietary shifts among consumers and their impacts. The authors found that younger populations (ages 15-45) respond to social norm behaviors, that is, as the world moves towards more vegetarian type diets, the change towards those diets is more rapid.

They argue that the values a society holds among peer groups can outweigh the influence of scientific facts. This was evident in that behavior shifts in response to health or climate risks were not as significant as motivators of behavior change. Secondary education attainment (a predominant proportion of the world’s population) and self efficacy and identity among women were also important motivators of dietary behavioral change. This study argues that for us, as individuals to make an impact on the environment through our diets, significant shifts need to be made by a large segment of the world’s population. These shifts require a movement towards a vegetarian type diet to reap both environmental and health benefits. Much of this change would happen through peer influence (think social media), through women’s agency, and through those with a secondary school education. The change, would need to happen on a grand, transformative level as called for by the EAT-Lancet Commission report in early January 2019.

Fires in the Brazilian Amazon. Source: NYTIMES

Foreign Policy well articulates the findings from the EAT Lancet and the IPCC report here and argue that the global food crisis is here. Now. Live. I also was on the Bloomberg Daybreak America’s show to discuss the impacts of the food system and diets on climate change. Check out the show here (segment starts at 1:22:50). Scientists have been forecasting their warnings for 40 years - they were right and no one listened. Maybe people (and governments) will start paying more attention and take some serious action. The NOAA show that July 2019 was the hottest month on record since they started recording temperatures. Speaking of heat, the Brazilian amazon fires are getting lots of attention right now. The NY Times shows a time scale of problem. It should be noted that these human induced fires are mainly done to prepare agriculture lands. And they occur every year, around the same time in the Amazon. The article makes three points on why these fires are different. (1) There were 35 percent more fires so far this year than in the average of the last eight years. (2) There has been a rise in deforestation in recent years, after a long period of decline. (3) While a large majority of the fires were on land that had already been cleared of forests many others are burning with particular intensity that are “deforestation fires.”

While we are discussing trees, it seems a banana fungus, known as “Fusarium wilt tropical race 4 (TR4)” has been devastating plantations in Asia and now the Americas. It is supposedly impossible to eradicate and can live in soil for 30 years. The economic upheaval cannot be overstated. Speaking of loss, a study out of Santa Clara University found that one-third of edible produce (like tomatoes, sweet corn, artichokes, watermelon, cabbage, strawberries and kale) remains unharvested in the fields. Reasons? Field/harvest stability, weather, pests and plant diseases, labor availability, market prices, and buyer specifications for how produce should look and feel like.

By the time we got to Woodstock…

I just can’t keep up with all the latest food trends. Did you know McDonalds has jumped on the podcast bandwagon? Yeehaw. Virtual restaurants are on the rise, meaning that they are digital-only establishments that don’t need a dining room or waiters. They rely on people ordering their food from apps. But kickin it back to ol’ school, this article gives ode to the Waffle House, started in 1955 in Avondale Estates Georgia. You just can’t replicate that with an app. Oh, how I reminisce of those bygone days. Can you believe Woodstock happened 50 years ago? I just bought this book: Hippie Food: How Back-to-the-Landers, Longhairs, and Revolutionaries Changed the Way We Eat by Jonathan Kauffman. Bring on the tempeh. Seems all things hippie are back in style. Keep an eye out for a blog dedicated to 1968-1969 and how it influenced our food ways.

Delving further back into history, the New York Times has an excellent piece on the “barbaric history of sugar” that fueled slavery in the United States. By the mid-19th century, the U.S. had 125,000 slaves working on sugar plantations! Fast forward to today, we are now trying to figure out how to reduce, remove or tax this “white gold” in the food supply. Forty countries and 7 cities have a sugar tax. The Economist highlights a study showing how to optimize sugar taxes without regressive effects. They suggest that: “In the real world, if taxes in one place get too high shoppers will arbitrage the rules by traveling to buy soft drinks elsewhere. Taking this into account they reckon that the optimal rate for cities is 0.5 cents, although a more efficient system would be a state or national tax to control America’s sugar rush.”

Impact of climate change on crops, water and income in Timor-Leste. Source: Bonis-Profumo et al 2019.

Here is just a few cool papers, reports and books that came out in the last few weeks:

• Association Between Plant-Based Dietary Patterns and Risk of Type 2 Diabetes: A Systematic Review and Meta-analysis. There is a strong inverse dose response association between plant-based diets and risk of type 2 diabetes This association was strengthened when healthy plant-based foods, such as fruits, vegetables, whole grains, legumes, and nuts.

• Soft condensed matter physics of foods and macronutrients. This article discusses the importance of physics in understanding the texture, taste, and composition of foods. It is an atom-colliding article of food science and matter physics. Get your genius on.

• Ravaged landscapes and climate vulnerability: The challenge in achieving food security and nutrition in post-conflict Timor-Leste. This article focuses on the fascinating Timor-Leste - an agrarian society that won independence in 2002 and is struggling to achieve food security and reduce undernutrition as the country modernizes. The economy depends on fossil fuel revenues and oil reserves are dwindling. A review of climate, agricultural, and nutrition data reveals high weather vulnerability, low agricultural productivity, and slow dietary and nutritional progress. But solutions exist. Agricultural sector actions can make important contributions to poverty reduction, food security, dietary diversity, micronutrient sufficiency, and overall nutrition. Agriculture can be made to be more nutrition- and gender-sensitive with a focus on mixed farming systems, biodiversity, climate-smart practices, and access to inputs, training, and technologies for farmers to enable sustainable and healthy rural livelihoods. Ultimately, productivity levels must improve to support the availability of sufficient and nutritious foods.

• Gene-environment interplay: what do our genes say about dietary choices? Those of us who work in public health often forget about epigenetics and the way our genes play out in our diets and health status. The authors say: “Diet is not just dictated by guidelines and individual choices, but also by availability and accessibility. Therefore, future studies that investigate the relationship of gene expression and a healthy diet in individuals exposed to a similar environmental milieu—for example, in accessibility, inducements, and the socioeconomic construct—are needed to understand the gene–environment interplay at the community level. These results can leverage genetic expression analyses to provide early biological footprints of an unhealthy diet environment, in order to facilitate the investigation of social factors that influence prevalences and outcomes of disease processes, such as food deserts and food swamps.”

• Trends and Correlates of Overweight among Pre-School Age Children, Adolescent Girls, and Adult Women in South Asia: An Analysis of Data from Twelve National Surveys in Six Countries over Twenty Years. The researchers found that overweight children had significantly higher odds of having an overweight mother and were more likely to come from wealthier households, live in urban areas, and have more education.

• Modernization of African Food Retailing and (Un)healthy Food Consumption. In Zambia, two-thirds of the households use modern and traditional retailers simultaneously, but richer households are more likely than poorer ones to use supermarkets and hypermarkets. Use of modern retailers is positively associated with higher consumption of ultra-processed foods, after also controlling for income and other socioeconomic factors. However, the use of traditional stores and kiosks is also positively associated with the consumption of ultra-processed foods, suggesting that modern retailers are not the only drivers of dietary transitions. Interesting!

• The SDG of zero hunger 75 years on: Turning full circle on agriculture and nutrition. In this paper, Derek Byerlee and I look back to the pioneering 1943 UN Conference on Food and Agriculture in Hot Springs, Virginia where the first international commitment to ending hunger was made. Despite these good intentions, however, the agricultural and nutrition communities largely went their separate ways for the next 50 years. Following through on the conference’s balanced approach of “more and better food” would have resulted in better nutrition for all. Today, the SDGs have once again put nutrition and agriculture together at center stage. Despite some important gaps in knowledge, financing, and implementation capacity, we are finally in a better position to shape food systems in a way that ends hunger and all forms of malnutrition.

• Technical Brief: Economic Evaluations of Multi-sectoral Actions for Health and Nutrition. This is a fantastic brief by the AHN Academy. This is a fantastic brief by the AHN Academy to “created to advance knowledge and scientific understanding among the global research community of economic evaluation methods and metrics related to costs and benefits of agriculture, food and livelihood strategies for nutrition and health.” They examine different types of economic evaluations and move towards standardizing a set of metrics to economically assess nutrition.

• The Political Economy of Food. Jody Harris and colleagues at IDS just published this IDS Bulletin that examines the issues of power across food systems. It looks at the various active players, relationships, activities, and institutions that play a major role in shaping food systems and power inequities. This was a much needed publication and I plan to use it in my class on food policy.

Su-su-summertime sadness

Summer is coming to an end and Lana Del Ray’s song, su-su-summertime, summertime sadness keeps running through my head. Not sure if I am sad it is coming to an end, or sad that it wasn’t the summer I dreamed it would be. But is it ever? Summer always starts with such high hopes. The stretched-out days, sun-drenched bronzed skin, quality time with nature whether it be in water or atop mountains, relaxing nights in the backyard, vacations, beaches. A time when the livin’ is easy. When “laziness finds respectability.” As Charles Bowden said, “summertime is always the best of what might be.”

Summer conjures up inspiration. Just think of the vast number of songs that have eloquently articulated that summertime feeling. Sly and the Family Stone, War, Bananarama, the Isley Brothers, Childish Gambino, the Motels, Seals and Crofts, Don Henley, Death Cab for Cutie, Lana Del Ray, The Lovin’ Spoonful, to name a few.

The posted playlist is just a sampling of “summer” songs. I purposely chose songs that had “summer” in the title, but clearly there are so many songs about summer, the anticipation of it, or the experience of it. Think Alice Cooper’s “Schools out for Summer”, The Go Gos “Vacation”, The Ramones “Rockaway Beach”, and anything by the Beach Boys…

Remember when square Sandy and T-bird Danny reminisce about their summer affair “summer lovin’ had me a blast, summer lovin’ happened so fast” in Grease? Oh the fleeting moments of young, summer romance…We’ve all been there.

But my favorite summer (sad) song has to be from Jonathan Richman of the Modern Lovers.

That summer feeling
When there's things to do not because you gotta
When you run for love not because you oughtta
When you trust your friends with no reason not ta (nada)
The joy I name shall not be tamed
And that summer feeling is gonna haunt you
One day in your life.

My summers always haunt me. The could’ves, the should’ves, the would’ves. I could have done more with my summer, or I could have done less. I should have done what the Italians do and take a whole month off to celebrate Ferragosto. I would have gone to the beach this summer and worked on my tan but alas, I don’t want to look like Keith Richards, an old leather shoe with lips.

So what the hell does this post have to do with food you may be asking yourself? Indulge me for just a few minutes more.

When I got to thinking about writing a post about summer and what it means for all things food, it got me thinking about seasons. The beginning of one season, ends another season. I feel that years go by faster when a place experiences four seasons - winter, spring, summer and fall. It can be refreshing - shedding skin, birth and death, light and dark. Winter is often associated with death, old age, pain, loneliness, despair or an end. Yikes. Spring is almost always associated with rebirth, renewal, hope. Summer, well, we have already expunged that season enough, but it does symbolize fullness, joy, and dare I say, freedom. August, often means bounty, change, maturity and maybe some anticipation of decay...

Lynch’s annoying twitter feed

When you live in a place like Arizona or California in the US, or in the southern tropics, you have sort of two seasons - hot and less hot, wet and dry. Back in 2009, David Lynch would annoyingly remind us on a daily basis of the wonderful, consistent, balmy weather in Los Angeles. And he wasn’t fibbing. Way to rub salt in the wounds of us New Yorkers struggling to stay alive amidst the bleak snow-covered streets and dead plantation.

The Earth’s tilt toward the sun and its trips around the sun dictates the cycle of seasons. The longest and shortest day of the year occur when Earth's axis is either closest or farthest from the sun also known as the summer and winter solstices.

Equinoxes are another significant day during Earth's journey around the Sun. On these days, the planet's axis is pointed parallel to the Sun, rather than toward or away from it. The spring, or vernal, equinox for the northern hemisphere takes place on the same day as the south's autumnal equinox and vice versa.

Seasons are so critical for food. Seasons bring different harvests of food that contribute to the diversity and quality of our diets. There are many studies out here looking at the seasonal affects associated with access to and availability of foods. Studies in Ghana, Bangladesh, and Malawi show that seasonality is a key element to food availability in many low-income countries, what is often called “local seasonality.” Seasonality impacts food access often through food prices of even the most basic staple foods. In many high-income countries, people don’t even think about seasons. You can get anything you want, any time of the year, what is called “global seasonality.” Blackberries in January, apples in June, corn in April. All completely off-season from when they could actually be harvested in the United States. Thank you global trade (take note Potus). We have become completely disconnected from the agrarian calendar. But more on that in a minute.

Jenny MacDiarmid, a fantastic researcher in Scotland, asked whether eating seasonal foods contributes to a more sustainable diet. One could argue that demanding global seasonality in a diet would provide nutritional benefits by increasing diversity of the diets, particularly perishable foods, but it could have high environmental costs. MacDiarmid argues that greenhouse gas emissions (GHGE) of globally seasonal food are not necessarily higher than food produced locally as it depends more on the production system used than transportation. She wrote: “Adopting a global seasonality approach to food supplies may not have major consequences for GHGE but to meet demands it could create greater water stress in already water scarce countries. A similar argument could be made against increasing the global supply of fresh food year-round because of the increased land it will require, which will have knock-on effects for loss of environmental biodiversity.”

Nigerian crop calendar

The agrarian or farm calendar is essentially the same as the crop calendar which is a time tool on when to plant, sow, and harvest local crops based in specific agro-ecological zones or landscapes. FAO has a bunch of examples based on crop or country. Here is an example of Nigeria. Yams looks like a solid bet for year-round food. This calendar shows maize across a few countries. It shows how diverse the planting and harvesting seasons are across the world, with some places getting in two harvests of corn per year.

Harvest calendar of the United States

It was always thought that the United States school year calendar was based on the agrarian calendar. The idea is to keep kids at home during the summer months (June through August), the most active time to plant and harvest. I even thought that was true. Turns out, it is not. Rural and urban schools had different calendars but summer was just a logical time for teachers and students to take breaks. According to this Washington Post article, “In the early 1800s, agrarian communities generally operated public schools for a winter and a summer term of two to three months each. The spring and fall, labor-intensive times for farming, featured no school. During the summer — no less important an agricultural season — older children were typically absent from school, since families counted on their labor.” Interesting. The myth of the United States education system still rooted in ancient agrarian times is a myth after all.

And if one were to look at the seasonal calendar of the United States, it would be near impossible to line that up with the current school year calendar of the country. The sheer diversity in temperatures, what is grown, where, and when, would put a child in each region of the country in a different academic calendar year, were it to be dependent on our farm systems. The harvest calendar of the United States based on temperature is shown on the right.

Seasonality also brings challenges associated with malnutrition. Due to seasonal variability of food production, dietary intake, food security and morbidity in the developing world, many children suffer from impaired growth or acute malnutrition issues. Seasonal malnutrition is often tied to disease burden brought on by seasons - rainy seasons bring about diarrhea incidence as one example. Stephen Devereux and colleagues published a PLoS paper about seasonal hunger and showed the patterns linking severe acute malnutrition and malaria during the rainy season in Niger.

Interestingly, when one searches for reviews in PubMed on seasonality and stunting (54 articles) or wasting (4) or undernutrition (220), very little emerges with most articles involving Vitamin D specifically. It shows how little the nutrition community pays to seasonality - which impacts interpretations of research findings of timed surveys and interactions with disease burden, programming and policy interventions. Andy Prentice has been studying seasonality for a good long time in The Gambia, and he wrote a paper back in 1994 on the topic. Crazy. Action Against Hunger wrote about it as a “missing link” a few years ago, arguing that seasonality rarely get attention by governments.

But how are seasons changing with climate change and what will this mean for malnutrition and our food security? A lot. We wrote about the seasonal affects on malnutrition in the context of near-term weather events, like El Nino and La Nina in the Global Nutrition Report in 2015 with Madeleine Thomson of Wellcome Trust. The report (check out chapter 6), articulates that for the poorest groups, the seasonal cycles of food availability, infection, and time use remain a significant challenge to nutrition security and provide a stark indicator of the vulnerability of populations to climate risk. The figure below shows how stunting varies by month of birth for Indian children under the age of three.

We also wrote about the impacts of seasonality in the context of climate change on the entirety of the food system. Forecasts of the future climate— whether short-term seasonal anomalies or long-term climate change scenarios—may also impact production and consumption patterns, price hikes of food staples, and social stability. And with climate change, the length and intensity of our seasons are getting harder to predict and harder to control. Farmers are challenged and will continue to be challenged.

Seasons. They are essential for the foods we grow, the diets we consume and our overall wellbeing. Seasons fill in the gaps and pauses that the world makes. But they are shifting, shaping and changing. Much of that due to the anthropocene.

My favorite season? You guessed it. Summer. But that summer feeling haunts me. As much as I want to hold onto it and its cumulative memories, it is gone as soon as it arrives. Although I tend to get sad when summer ends, I am glad when it comes around with each passing year.

Food Bytes: July 8 - July 20

Food Bytes is a weekly blog post of “nibbles” of information on all things food and nutrition science, policy and culture.

Food environments seem to be on the tip of the tongue for everyone these days. Food environments are the “collective physical, economic, policy and sociocultural surroundings, opportunities and conditions that influence people’s food choices and nutritional status.” Or to put it more simply, it is the place where consumers go to buy or order food - a market, a restaurant, a cafeteria.

The UN Standing Committee on Nutrition, also known as UNSCN, has just published a collection of papers on the food environment. It splits up the food environment into two entry points - the food supply shaping these environments and the consumer demand side - and what it would take to make change, also known as the enabling environment. The publication is chock-full of case studies from all over the world. I like the ones on Mexico, the private sector last mile, the flathead reservation, cash transfers, and the digital influence.

In South Africa’s Soweto hood, women struggle to be healthy. Food environments are pretty dismal (fries, fries and more fries), and exercising outside can be dangerous. It is not just about supply and demand of healthy foods, which the UNSCN publication focused on, but the whole built environment, the way women are treated in our society and urban safety. At the same time, its seems many South Africans are taking food security into their own hands. One study found that 2.2 million households have recently constructed food gardens at their homes in order to avert food insecurity.

While we are on the lovely UN, the UN Committee on Food Security is rolling out a series of regional consultations on what is known as the Voluntary Guidelines on Food Systems and Nutrition. This stems from the High Level Panel of Experts on Nutrition and Food Systems report which called for these guidelines to be developed by governments collectively and collaboratively. These voluntary guidelines are meant to create a global norm of reference in the governance of food systems and nutrition/diets. The guidelines outline principles and practices that governments can refer to when making laws and administering food systems. These guidelines should be seen as an internationally negotiated soft law or a set of guidelines in which all governments have reached a common ground. So, they can be important, and quite powerful. Anyone can comment on the zero draft - far from its final - here. The regional consultations started in Africa, Ethiopia. Then, Asia, Bangkok. Then Central and South America, Panama, North Africa, Egypt, Europe, Budapest and last but not least, North America. I had the pleasure of being at the Ethiopia meeting and it was quite fantastic to have so many African countries in one room talking about African food systems. Amazing stuff.

Speaking of Africa, the diversity of cuisines and culture is what makes the continent so amazing. Take Nigeria. Reading Yewande Komolafe’s recipes made me want to jump on a plane to Lagos and eat my way through it.

But it is not always a rosy picture for Africa. The continent is still struggling with food insecurity, while at the same time, obesity is creeping up, up and up. The FAO State of Food Insecurity (SOFI) 2019 report just came out, two months early. It was reasoned that it came out to line up with the High Level Political Forum. Yeah sure. I think it was timed to be released right before the Director General, José Graziano da Silva stepped down to celebrate his 8 years as the leader of FAO. However, the report is nothing to celebrate. I digress…The major findings of the SOFI were the following:

• More than a quarter of the world’s population now struggles to eat safe, nutritious and sufficient food.

• Hunger is on the rise in most of Africa, in parts of the Middle East and in Latin America and the Caribbean. The situation is most alarming in Africa, where since 2015 undernourishment has steadily increased in almost all subregions. In Asia, undernourishment has been decreasing in most regions, reaching 11.4 percent in 2017. In Latin America and the Caribbean, rates of undernourishment have increased in recent years, largely as a consequence of the situation in South America.

• Economic shocks are contributing to prolonging and worsening the severity of food crises caused primarily by conflict and climate shocks.

• No region is exempt from the rising trends of overweight and “obesity rates are higher in those countries where moderate food insecurity is also higher.”

We see this in the United States too. I just wrote a piece for Bloomberg Opinion (I didn’t choose the photo.) showing that food insecure adults in the U.S. are 32% more likely than others to be obese — especially if they are women. Poverty and unemployment have driven the dual rise in food insecurity and obesity since the 1960s, especially in rural America. But many city dwellers subsisting with inadequate social services and support structures are also susceptible. Every time I write a piece in Bloomberg Opinion, I always get lots of interesting email comments. For this piece, most commenters feel that if you are fat, it is your fault. If healthy foods are available, affordable and easy to access, “these people” will always make the wrong choice. My reaction? WOW. It is so hard to eat healthy in our perverse food environments. Blaming and shaming is not going to make things better. But it seems, consumers are catching on in the U.S. - diet quality is improving.

But what does the latest evidence suggest for those who are overweight and want to lose weight? I will soon dedicate a longer blog to this issue because the literature is confusing. Is it a keto diet? Is it intermittent fasting? Is it low-carb? Is it putting a teaspoon of oil in your coffee every morning? New evidence suggests that cutting 300 calories per day, from any food, can lead to substantial weight loss in adults (7.5 kilos over two years) compared to the control group. Tamar Haspel of the Washington Post, argues that eating ultra-processed foods comes down to increased calorie consumption. We consume more of those foods, and they are calorically dense. She wrote:

“In a nutshell: The root of obesity is palatability and calorie density, combined with ubiquity and convenience. Satiety hormones and other metabolic machinations have much less to do with it. We’re responding to cues from without, not from within. One new study doesn’t prove it, of course, but it’s the hypothesis that best fits the preponderance of the evidence.”

I really appreciate this article that “Being Fat is Not a Moral Failure.” Damn straight. This Scientific American article argues “Individual behavior change is ineffective in the face of social and structural barriers that constrain individual choice. These barriers are uniquely relevant among racial and ethnic minorities and impoverished adults who are more likely to be obese.”

A bunch of scientific papers and media articles came out this week on diets, nutrition, and food systems. Here are some highlights.

• “Ultra-processed” foods or what I call, junk food, are in the news again. This article outlines four dangers with food reformulation - redesigning an existing processed food product with the objective of making it healthier. This article argues that reformulation just tinkers around the edges, and isn’t really fixing the root problems of the food system, and what the authors say is food and beverage industries.

• Case in point? Nearly 10,000 cases of heart disease and stroke and 1,500 cases of cancer could have been avoided in England if the government had not switched to a voluntary deal (as opposed to mandatory) with the food industry to cut salt in food. England is doing so much good stuff in the food space right now, but man, there are potential setbacks with Brexit and political shifts. This BMJ post by Annie Purdie and colleagues is concerned about Boris Johnson’s recent decision to look at “sin taxes” and creating a nanny state. The authors argue that the public health community needs to “move beyond debating the cost-effectiveness of interventions, and engage with the underlying political nature of the issue.” We need to pay more attention to the language (sin, nanny, liberties etc) used to highlight the problem and the proposed solutions like taxes on soda and regulating the levels of salt and sugar in foods. As Bob Marley sang, “don’t let ‘em fool ya.”

• There is more and more coming out that nutritional sciences is “broken.” In this article, they use the “eggs are again bad for you” study that came out in JAMA. Waah. Is it? I disagree! Of course, when we focus on specific foods and nutrients, the data is not clear, but dietary patterns show basically the same thing. Give it a rest dudes.

• While these researchers argue that more evidence is needed, they did find that snack foods and sugar‐sweetened beverages are providing a substantial proportion of energy intakes (ranges from 13 to 38%!) among children below 2 years of age in Latin American and South‐east Asian low and middle income countries.

• A study in the capitol of Nepal, Kathmandu, showed just that consumption of unhealthy snack foods and beverages contributed 47% of total energy intake among the wealthiest consumers, compared with 5% among the poorest. This pattern of junk food consumption among young children was associated with inadequate micronutrient intakes. The reason that mom’s give these foods to their children? Convenience - they are easy to prepare and easy to feed. Makes sense. Looks like even among very poor countries, we are seeing the nutrition transition play out in real time. Ever try making dal bhat from scratch? Not easy and incredibly time consuming…

• I love that the Lancet is calling on oral health researchers to review the evidence and conflicts of interest of the impacts of what we eat on our dental health and the caries that come with sugar consumption. The lead scientist argues, and this goes back to the infant studies: “A particular concern is the high levels of sugar in processed commercial baby foods and drinks which encourage babies and toddlers to develop a preference for sweetness in early life. We need tighter regulation and legislation to restrict the marketing and promotion of sugary foods and drinks if we are to tackle the root causes of oral conditions.”

• New microbiome research shows that a specialized food made up of chickpeas, soy, peanuts, bananas and a blend of oils and micronutrients substantially boost microbiome health in severely malnourished children. Yummy.

• Do cookbooks need nutrition labels? Great question but sort of takes the fun out of cookbooks no?

Derek Byerlee and I wrote a piece looking back 75 years on commitment to hunger when the first international commitment to ending hunger was made at the UN Conference on Food and Agriculture, at Hot Springs, Virginia, USA in 1943. That conference set the goal of ‘freedom from want of food, suitable and adequate for the health and strength of all peoples’ that should be achieved ‘in all lands within the shortest possible time’ (US Department of State, 1943). It is sobering and shameful that 75 years after this clarion call, as well as the dozens of similar global declarations since 1943 for ending hunger, some 800 million persons are estimated to be undernourished and over 2 billion adults and children suffer from other forms of malnutrition be it obesity or micronutrient deficiencies. We remind readers of the significance of the Hot Springs conference and briefly trace the long road that has led us back to the original vision of ending hunger that recognized the several dimensions of nutrition, from undernourishment to micronutrient deficiencies. While there has been progress, this reflection over 75 years helps appreciate the fact that today for the first time, the links of agriculture, health and nutrition outlined in 1943 are again at center stage in the global hunger challenge as embraced in SDG2. Accordingly, SDG2 offers a better foundation for accelerating progress in reducing malnutrition in its several dimensions, although we recognize major gaps in knowledge, financing, and implementation capacity for realizing SDG2 targets.

Someone else is realizing the importance of agriculture. It seems Bill Gates has woken up to the fact that the CGIAR exists. His article is titled “You’ve probably never heard of CGIAR, but they are essential to feeding our future.” Hate to spoil it Billie Boy, but we have heard of the CGIAR…and I don’t confuse it with the word “cigar,” cigarillos, ciggies, or ziggie stardust.

On the environmental and climate change front, lots going on. The World Resources Institute released a mother of a report - 564 pages - on Creating A Sustainable Food Future. You may have seen the abbreviated version released 6 months ago. But this one goes into great detail a 22-item “menu” which is divided into five “courses” that together could close the food, land and greenhouse gas gaps: (1) reduce growth in demand for food and agricultural products; (2) increase food production without expanding agricultural land; (3) protect and restore natural ecosystems; (4) increase fish supply (through improved wild fisheries management and aquaculture); and (5) reduce GHG emissions from agricultural production. Richard Waite and Janet Ranganathan are seriously my heroes in creating these action oriented solutions. Well done.

Following on the heals of that report, two Lancet Planetary Health papers came out. One paper shows that even under optimistic socioeconomic scenarios future supply of fruits and vegetables, central components of a healthy diet, will be insufficient to achieve recommended levels in many countries. Consequently, systematic public policy targeting the constraints to producing and consuming fruits and vegetables will be needed. The second paper shows climate change and increased atmospheric CO2 will impact the availability of protein, zinc and iron availability. The many countries that currently have high levels of nutrient deficiency would continue to be disproportionately affected.

This expose by the Guardian shows that Brazil’s huge beef sector, and the appetite for beef, continues to threaten health of world’s largest rainforest, the Amazon. This is just downright sad.

And while those of us in nutrition don’t really get to the larger social determinants of food insecurity and malnutrition, it is important to do so. This article in NPR’s Goats and Soda delve into the practice of trading sex for fish in Lake Chilwa in Malawi. This is driven by poverty and food insecurity and the impacts are catastrophic in this southern African country - HIV, violence and stigma - for these women.
