There is much to catch up on in this month’s Food Bytes. The fall season here in the U.S. always brings a lot of productivity. There seem to be more meetings, more papers, and more output. We just finished the UN General Assembly and Climate Week in New York. I love seeing so many friends and colleagues come to town, but it is exhausting. There are so many “side” events. We hosted a Bollinger Convening at Columbia’s Climate School that brought together some of the best people in the food systems field, including the President of Malawi, the PM of Haiti, and the First Lady of Brazil. Good times were had by all, but I deeply wonder if all the time, money, and greenhouse gases spent flying to NY actually amount to meaningful change. There were swanky events where people were nibbling on gourmet hors d'oeuvres, drinking champagne cocktails, and pontificating about solving poverty through quick tech fixes…It is a bit nauseating, to say the least. The same goes for COP, Davos, etc. As one of my colleagues said, “Just say you want to bring all your friends into town and have a big party. But don’t think you will solve the world doing so.” Point taken. Ollie Camp at GAIN did an excellent re-cap for those who couldn’t make it to Gotham. For an even briefer re-cap, all the food-focused events seem to be honing on two topics: (1) regenerative agriculture (what exactly is it?) and (2) the livestock conundrum. The UN produced a Pact for the Future with 56 actions for a global transformation protecting present and future generations. Is this the next set of Sustainable Development Goals?

Reports

The Tilt Collective, a new initiative focusing on plant-based foods, made a big splash at Climate Week. It will be interesting to see where they go. They have a report to explain their plan further, and the CEO, Sarah Lake, summarizes her modus operandi on a Tedtalk that can be found on the Tilt homepage. The Gates Foundation also released its Goalkeepers report and had a splashy event at Climate Week, focusing on nutrition. They argue that “No other global health problem requires a larger-scale solution than malnutrition.” I tend to agree…

Speaking of nutrition, the World Bank released their much anticipated Investment Framework for Nutrition. They argue that scaling up nutrition interventions to address undernutrition globally will require an additional $13 billion annually over the next ten years (2025-2034). This would mean $13 per pregnant woman and $17 per child per year under five years. This investment could avert 6.2 million deaths in children under age five and 980,000 stillbirths over the next decade.

Food systems are garnering attention from less traditional UN bodies. UNDP released a white paper on food system transformation. I'm not sure it says much more than what we already know. UNEP has a rich interactive site called the Journey of Food. The most depressing report of all is the WWF’s Living Planet Report. The average size of wildlife has decreased a staggering 73% since 1970. Most of that is driven by habitat loss (see the figure to the right showing the drivers of species loss in North America), mainly from agriculture. Read the report — it is depressing but critically important for our planet and us.

Science papers

It is getting hard to keep up with food-climate-nutrition scientific output these days because there is just so much of it. This is a good problem to have. Here are some highlights of what I have been reading over the past two weeks.

• Nature Food’s September issue is rich in sustainable diet science. I appreciated Loken and colleagues' paper on the importance of culture to diet health and sustainability.

• If you want to double down on your doomsday depression about the state of the planet, Ripple and colleagues deliver yet again! Bottomline? We are so screwed.

• Emmerling and colleagues have a fantastic paper in Nature Climate Change that examines the relationship between climate change and inequality. The scientists model that by 2100, climate impacts will increase inequality by 1.4 points of the Gini index on average. If we stay within the Paris Climate Agreement to stay below 1.5 °C, long-term inequality increases by two-thirds but increases slightly in the short term. It's so great to see this topic getting some attention.

• Last, the Lancet published the Earth Commission report. In it, they “quantify safe and just Earth-system boundaries and assess minimum access to natural resources required for human dignity and to enable escape from poverty. Collectively, these describe a safe and just corridor essential to ensuring sustainable and resilient human and planetary health and thriving in the Anthropocene.” It is a long read but worth it.

• The Food Compass, out of Tufts University, has published its second paper, improving on its nutrient profiling system that assesses the healthfulness of diverse foods, beverages, and meals. Their score, named FSC grouped foods into three categories: foods and beverages scoring ≤30 are those to be minimized, foods and beverages scoring 31–69 are those to be consumed in moderation, and foods and beverages scoring ≥70 are encouraged. They found that among all products, 23% scored FCS ≥70; 46%, FCS 31–69; and 31%, FCS ≤30. Most beverages (54%) and animal fats (92%) scored ≤30; whereas most meat, poultry, eggs and dairy scored 31–69. Most products within seafood, legumes, nuts, vegetables and fruits scored ≥70 (82%, 80%, 89%, 63% and 53%, respectively. Nothing too shocking no?

Media

Of course, our favorite media outlets are always generating some food journalism.

• This BBC piece is balanced about the ultra-processed nature of plant-based alt foods. Thanks for sending it my way Hermano Herrero!

• The FT has highlighted this notion that the US has reached peak obesity. Is it behavior change or ozempic?

• The scorching and dredging of the Amazon is happening, and the potential devastation to ecosystems and those who depend on its mighty waters is for realzzzz. Brings me back to the piece I wrote about rivers.

• The hippie-dippie Erowon-esque food crazes won’t die, and the city of Los Angeles leads the way in blisfull ridiculousness. This New Yorker article captures the insanity well.

• Love tuna? So do I but should we be eating so much of it. The NYT fishes around for the deets.

• Speaking of tuna, I started watching the series, Omnivore, curated by the chef, Rene Redzepi. Each episode focuses on a singular food or ingredient. The first is on tuna. Great watch about the importance of food across many cultures.

And that’s about all she wrote for this month. Just some final closing words. This month was not the easiest for many people. Some parts of the world are in intractable conflict. My parents lost just about everything in Hurricane Helene, and my good friend Richard Deckelbaum passed. And the U.S. election has me filled with much dread. Yesterday, I turned 53 and have much to be grateful for. My parents are alive and okay. Richard led a long, amazing life. And people are out there fighting the good fight for democracy, climate action and the world's wellness. I am filled with hope. And not the kind of hope that is a belief that everything was, is, and will be fine. It is the kind of “hope” about the possibilities and the actions for our future.

Food Bytes: Aug 2024 Edition

FOOD BYTES IS A (ALMOST) MONTHLY BLOG POST OF “NIBBLES” ON ALL THINGS CLIMATE, FOOD, NUTRITION SCIENCE, POLICY, AND CULTURE.

It’s been a while, well, the whole summer, since I have written a Food Bytes blog. This summer was full of guilt-free laziness, ice cream eating, and beach combing. Witness the delicious vanilla Mr. Softee cone. On those sticky, hot, humid dog days of summer in NYC when nothing seems to be going right, this will do me just fine. But ketchup-inspired ice cream? That’s a hard no for me. Oh, but there was plenty of consumption of this on those long summer nights and some earlier “draft”ernoons. Pizza always comes to mind when discussing NYC and food in the same breath. Did you know NYC has gone through 4 evolutions of pizza making? Forgeddaboudit. Call me crazy, but I am still focused on the first evolution, and I’m stickin’ to it.

We saw lots of good music over the summer including DIIV at the beautiful Brooklyn Paramount, Jessica Pratt, OFF! (with the legendary Keith Morris), and Horse Lords in central LA. I also found myself not reading many scientific articles over the summer. Why do that to oneself when days can be spent lollygagging on grassy knolls? Instead,…wait for it…I read books! What a concept. But this week, I did manage to catch up on some light reading, and here are some highlights.

The New York Times has a new series of op-eds, “What to Eat on a Burning Planet.” A real picker-upper on the title alone. David Wallace Wells started the series with an op-ed on how food supplies will change and how climate change threatens the ability to continue to generate the yields needed to feed a growing population. There are a host of other good op-eds worth the read.

The Economist, a British weekly news magazine, hasn’t always given nutrition and food much attention, but lately, they seem to have changed their tune. I am a big fan of the Economist — this idea that you don’t know who the writers are behind the stories, their bravery in calling things as they see them, and, of course, the fantastic writing. They have paid homage to food and nutrition in three great articles.

• They call for big food to contend with ultra-processed foods. They say, "If pressure from governments ratchets up, the food industry will have to do more than tweak its recipes or roll out new product lines. Companies would have to completely overhaul their manufacturing processes.”

• They also focused on the idea that small investments in early child nutrition can make the world smarter and that undernutrition across the world persists. This is not new to those working in international nutrition, but it is nice to see broader attention to the topic.

• At the same time, obesity is rising and seems unstoppable. The Economist argues that drugs (like the GLP-1 class) and taxes won’t be enough. The question is, why don’t we have more solutions that work, and why has no country been able to stop this trend? Don’t say it is willpower, please….

A lot is happening in the ongoing debates of livestock and meat production and consumption — one of the most juggernaut issues in food systems. Here are some highlights:

Source: Herzon et al 2024 Nature Food

• The Good Food Institute—a nonprofit organization that promotes plant- and cell-based alternatives to animal products, particularly meat, dairy, and eggs—released a report that argues if Americans replaced 50% of their animal consumption (meat and dairy) with plant-based foods, 47.3 million fewer acres of cropland would be needed to grow that plant protein. Let’s see how that goes down with the livestock sector.

• According to Vox, environmental NGOs help greenwash the livestock industry’s climate impact. They use the example of the World Wildlife Fund and their relationship with McDonalds who are part of a round table on sustainable beef (with WWF accepting millions from McDonalds to assist in the roundtable collaboration. Yikes.

• More and more studies are better articulating the impacts of red meat consumption on non-communicable disease outcomes. This meta-analysis further confirms that a higher intake of red meat and processed meat increases the risk of type 2 diabetes incidence. A microsimulation model estimated that a 30% reduction in both processed meat and unprocessed red meat intake could lead to 1,073,400 fewer occurrences of type 2 diabetes, 382,400 fewer occurrences of cardiovascular disease, 84,400 fewer occurrences of colorectal cancer, and 62,200 fewer all-cause deaths over a 10-year period among an adult US population.

• The evidence is building…maybe leading to more statements such as this. The question is, how? These authors suggest downsizing livestock herds and for those that remain in existence, ensuring they are sustainable and present a framework (see figure above) for how sustainable livestock systems fit into a safe operating space.

• And what we don’t talk about enough is animal and human welfare associated with our unlimited appetite for animal meats. Michael Holtz wrote an illuminating and devastating account about working in a Dodge City meatpacking plant during the COVID-19 pandemic in 2021. I also highlighted the issue of young immigrant teenagers working in dangerous conditions at slaughterhouses in a past Food Bytes post.

Food prices, cost, and affordability are hot topics these days. Kamala has made minimizing food price gouging part of her future economic plan if she were to become president-elect. Some disagree with her strategy. The FAO’s State of Food Insecurity Report released its latest data on food affordability. While the number has come down this year from 3.1 to 2.83 billion people who cannot afford a healthy diet, it is still shockingly high and inequitable across regions of the world. FAO says: “In 2022, the number of people unable to afford a healthy diet dropped below pre-pandemic levels in the group of upper-middle- and high-income countries as a whole, while the group of low-income countries had the highest levels since 2017.” But still, food prices continue to rise, pushing up the cost of a healthy diet year on year. In 2022, costs went up 11% in just one year. A group out of IFPRI suggests that the cost and affordability of healthy diets need more investigation into their accuracy and if assumptions of these metrics skew what is actually affordable. Their analysis argues that the EAT-Lancet diet is not affordable for 2.13 billion people, not the 3.02 originally reported. I am not an economist or a specialist in this topic, so I cannot agree or disagree with these findings. However, I am a scientist, and opening debates and discussions on metrics is a healthy pursuit to get to the truth. In another paper published in Nature Food, authors analyze per capita budget shares for food and an additional 12 raw food categories, including ultra-processed food and beverages, across 94 countries from the period 1990 to 2019. They found that food expenditures are not the same worldwide, and low-income food demand does not necessarily mirror high-income demand. Of course, budget allocations align with income levels, food trade and production, and culture. Check out this figure to see how much it diverges across low to high-income countries.

A few other Bytes: This paper on the climate-food-migration nexus by Megan Carney is a doozy but so important. Hulsen et al. published a paper on how local food environments impact children’s diets. They did this work in Malawi and found significant differences between rural and urban food environments, and that, of course, access to more variety of foods in these markets has positive impacts on children’s diets. The New York Times has highlighted a study on tipping points that may just put the fear of god in you. Die-offs! Collapses! Ghostly coral reefs! Seriously, these are scary outcomes if we do nothing about climate and the science on tipping points has momentum. Speaking of tipping points, has Italy’s marine ecosystem reached one, and the result is blue crab invasions and infestations? In the worst-case scenario, tipping points could lead to massive destruction of precious ecosystems, food insecurity for billions, and, in some cases, famines. The world has witnessed cataclysmic famines in the past. The question remains as to why Gaza and Sudan have not been declared as famine states. NPR explains. Declaring a famine is not so simple…but it doesn’t mean inaction and complacency.

And if you need some recommendations on keeping up with the latest food systems news, if you don’t read and support Civil Eats, do so. If you were a fan of The Counter and were devastated when they closed shop, have no fear. Grist has come to the rescue, and their food reporting is awesome.

And for those of you who tear up every time you hear Gillian Welch’s Time (the Revelator), she and her partner, David Rawlings, have a new album out. It may just help you laze away the last days of summer. Enjoy!

'Coz I'm the tax man

I get asked a lot about whether taxing soda is effective. There has been a lot published on taxing food and beverages that are deemed bad for us. So what gives? Does taxing soda have any impact on our health? This is my take on the science, but first, let this jig run through your head….

Should five percent appear too small
Be thankful I don't take it all
'Cause I'm the taxman
Yeah, I'm the taxman

I'll tax the street
(If you try to sit, sit) I'll tax your seat
(If you get too cold, cold) I'll tax the heat
(If you take a walk, walk) I'll tax your feet

TAXMAAAAAAAN!!!

Sugar-sweetened beverages (SSBs) are nonalcoholic beverages containing added caloric sweeteners. In addition to carbonated soft drinks or sodas, SSBs include energy and sports drinks, less-than-100-percent fruit or vegetable juices, ready-to-drink teas and coffees, sweetened waters, and milk-based drinks. SSBs are widely consumed worldwide, and the retail sales of these beverages have been increasing over the last decade. Their consumption has been associated with obesity, diabetes, heart disease, and other detrimental non-communicable diseases (NCDs). Because of their unhealthy nature, the World Health Organization has included a range of policy priorities, including SSB taxes, to help countries combat NCDs and improve the overall health of the global population.

Taxes on SSBs have been introduced in 118 countries, with 105 at the national level and 13 at the subnational level, covering 51% of the world’s population. Most SSB taxes are implemented using excise taxes (88%), with a handful of other countries implementing them through mechanisms such as import taxes, differential Value-Added Tax (VAT), Goods and Services Tax (GST), or regional sales tax (see the figure below). These excise taxes occur mainly as tax pass-throughs, in which the price increase of the taxed product falls on the consumer. In the U.S., for example, 70% of SSB taxes are passed onto consumers through higher-priced SSBs.

Types of SSB taxes being implemented around the world

In a systematic review and meta-analysis of 62 empirical studies of SSB taxes across 45 countries, the majority of SSB taxes were implemented as a tax pass-through. While the impacts were heterogeneous across the countries, the demand for SSBs was sensitive to tax-induced price increases, with a mean reduction in sales of SSBs by 15%. The sales resulted in no substitution towards healthier, untaxed beverages (e.g., bottled water). Another review argued that SSB taxes provide no substantive changes to dietary or purchasing behavior due to the lack of substitution towards healthier alternatives. Another study found that while SSB taxes modestly reduced the purchases of some taxed beverages in the taxing jurisdiction, consumers respond to the taxes by increasing cross-border shopping, in which they go outside the taxing jurisdiction and buy those same taxed beverages at a lower cost. However, taxes may spur downstream effects on other industry responses and policies, including reformulating products to reduce sugar consumption in those beverages, as was seen with the graduated sugar tax implemented in the UK.

Of the tax policies around the world, 73% are implemented in low- and middle-income countries (LMICs), with the highest in South Asia. However, LMICs face many challenges in implementing SSB taxes, including a lack of political will and resources, weak national capacity to implement policies, large informal food sectors, and substantial influence of the food and drink industry on policy development.

The question remains whether SSB taxes can result in healthier dietary patterns and reduce the health implications accompanying excess consumption of these products – particularly NCDs. Most of the evidence — particularly from  Nakhimovsky et al., 2016; Niebylski et al., 2015; Teng et al., 2019; and Thow et al., 2014 — suggests that SSB taxes have impacted the purchases of taxed products to varying degrees, but not necessarily long-term and impactful behavior change towards healthier diets and improvements in health. One potential reason may be that the SSB taxes translate to only a 5 to 22-kilocalorie reduction per capita daily. This is insufficient to have a meaningful impact on disease outcomes. Some researchers suggest that one way to deal with this is to raise the current tax rates from the current approximate 5% to 20%. This would also be aligned with the WHO’s recommendation for at least a 20% tax on SSBs. Several countries, such as Qatar and Saudi Arabia, have substantive (50-100%) excise taxes on SSBs, which are more in line with the taxation rates of tobacco.

The question is whether other foods, particularly red meat, should be taxed due to their significant implications on the environment and contributions to climate change. While consuming red meat in high amounts can contribute to NCDs, red meat is also a source of important nutrients. If a tax on red meat makes them prohibitively expensive for those who already struggle to afford these foods, it could put these nutrient-dense foods even further out of reach for the world’s poor. Thus, a “carbon tax” on red meat might be appropriate in wealthy countries with strong social protective measures and in countries with disproportionately high levels of red meat consumption.

Food Bytes: November 2023 Edition

FOOD BYTES IS A (ALMOST) MONTHLY BLOG POST OF “NIBBLES” ON ALL THINGS CLIMATE, FOOD, NUTRITION SCIENCE, POLICY, AND CULTURE.

I thought I would write up the November Food Bytes before the onslaught of publications leading up to the COP28 climate meeting takes place. Here is the roundup!

Some interesting articles and books:

The great “godfather of climate science,” Jim Hansen, also a Columbia colleague, has put out a paper with colleagues arguing the planet may be warming faster than previous estimates have indicated by measuring “climate sensitivity” – measuring the earth’s warmth via atmospheric carbon dioxide concentrations. Global CO2 levels hovered around 280 parts per million in the pre-industrial age. Now, they are above 400 ppm. Not everyone agrees with this paper, but no matter, Hansen is sending us clear warnings.

We are more and more worried about how resilient our food systems are in the face of extreme events and shocks, be they climate, environmental, or political. This paper examines the impacts of crop yields related to several agriculture input shocks – nitrogen, phosphorus, and potassium, machinery, pesticide, and fertilizer. Industrialized agriculture systems depend on these inputs, and often, they are imported from other countries. When combined, as you can see in the figure, some areas showed decreased yields for some but not all crops. The yields of barley, maize, potato, and wheat decreased heavily in the western United States. Barley, maize, millet, potato, sorghum, and soybean yields all decreased in northern Argentina, while barley, maize, potato, and wheat. To some extent, sugar beet also saw large yield decreases in Central Europe. Rice yields, in turn, decreased heavily in Thailand, Vietnam, and the southern part of India.

My friend Bill Dietz, the Director of Sumner M. Redstone Global Center for Prevention and Wellness at George Washington University, and I just published a paper on how the U.S. agri-food sector can contribute to climate change mitigation. The paper is timely for the upcoming COP28 meetings. The U.S. needs to step up!

A new book on the political economy of food system transformation co-edited by Danielle Resnick and Johan Swinnen has been jointly published by IFPRI and Oxford University Press. The summary follows: “The current structure of the global food system is increasingly recognized as unsustainable. While the need to transform food systems is widely accepted, the policy pathways for achieving such a vision often are highly contested, and the enabling conditions for implementation are frequently absent.” Check it out and download it for free here.

Some interesting reports:

Every year, the UN Food and Agriculture Organization, also known as FAO, releases two flagship reports: the SOFI and the SOFA. The SOFA just came out this past week and focuses on the “true cost of food.” That means they assess the hidden environmental, health, and social costs of producing our food. What is their final assessment? Global hidden costs of food amount to 10 trillion dollars, with low-income countries bearing the highest burden of hidden costs. Yikes.

The Global Alliance for the Future of Food released an interesting analysis in this report calling for food systems to wean off fossil fuels. Wouldn’t that be nice….They argue that food production, distribution, processing/packaging, storage, and sales consume about 15% of all fossil fuels generated annually. They argue that the fossil fuel industry holds a lot of sway with governments, making it difficult to “extract” (sorry for the pun) their influence or hold them to account.

A report by the group I-CAN, which looks at the integration of climate and nutrition, came out. It is interesting…nothing new…and much built on the long scientific publications already out there, but I supposed putting it in a layperson report gets the message out there.

Some interesting listens:

Vice did an “expose” on how the Italian mafia has taken over food systems in Italy. Having lived in Italy and interested in Italian deep food traditions, I watched it. The document is not well done, with much speculation and little evidence beyond a few interviews. If it is even true, I wasn’t convinced by this documentary.

John Oliver’s Halloween episode focused on the issues of child labor related to producing chocolate – focusing on Ghana and the Ivory Coast, where roughly 60% of it is produced. A lot of the material is borrowed from Netflix’s Rotten series. Still, the message is clear that many children (1.56 million) are engaged in cocoa production stemming from insufficient wages paid by massive confectionary companies to smallholder farming families working or owning cocoa farms, leaving them in gut wrenching poverty. Such a tragedy. I don’t think John Oliver adds much to the debate – if you want a quick watch, go to the Netflix episode.

In their usual snarky, pick-it-to-pieces style, Mike and Aubrey of the fantastic Maintenance Phase podcast sink their teeth into Ozempic, the weight loss diabetes treatment drug. It's well worth listening to the latest.

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.

Food Bytes: June 1st Edition

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

Indeed, it has been a while. One would have thought that the COVID-19 pandemic would have made me more productive—there is so much to blog about! Alas, for some of us, we’re okay going “underground” so to speak.

Speaking of underground, cicadas have emerged—the Broods (X) are back after a 17-year slumber. What does that have to do with the pandemic? Well, everything and nothing. My guest blogger and better half went hunting to cook some up. And let me tell ya, they are scrumptious. Truly. I too spoke about them on NPR and CNN.

COVID-19 has us not only experimenting with grubs but has upended our entire lifestyle. This NY Times piece argues that as we emerge from a year ++ of inactivity and less than normal eating patterns, we do not have to give in to all the diet fads that companies want you so badly to believe and buy. The video is quite thoughtful.

So many podcasts on food…but I like Point of Origin. This one, on “food apartheid” as opposed to “food desert” is particularly interesting.

Speaking of podcasts, I am pretty excited about my book that is coming out on June 22: Can Fixing Dinner Fix the Planet? I spoke to Jeremy Cherfast of Eat This Podcast about the book and fixing our food systems.

The UN Food Systems Summit is gearing up for better and for worse. There is a lot of chatter, dialoguing, planning, and writing on the peripheries. Corinna Hawkes, my go-to on all things food systems, has been keeping up her blog sharing gems of thoughts on leadership, inclusion, and what it means to truly change food systems around the world.

Some other random media nuggets that caught my eye this past week or so:

• NYT questions the measurement of Body Mass Index. It’s about time…

• Inspiring article in Mother Jones about black farmers reclaiming land that is rightfully theirs.

• Mark Bittman has written another book and this one hits hard at the U.S. food system. Always provocative, here are some of his thoughts on what needs to change. Alice Waters weighs in too.

• Should we have a scientific body that weighs the evidence on food systems? Some say no. Why? Because it already exists. Yes, it does but it needs help…

We cannot end any Food Byte edition without highlighting some of the fantastic science being generated on all things food. Here are a few gems:

• Animal source foods reduced stunting in young children in Bangladesh and Nepal. Nature Food.

• A modeling exercise looked at the cost-effectiveness of food programs on saving children’s lives. Bottom line, they make an impact. Global Food Security.

• A call to action for a one-health approach to avoid future land use-induced spillover events. Lancet Planetary Health.

• Interesting perspective of pastoralists and another piece on their resilience. One Earth and Aeon.

• You say you want a food systems data revolution? Well, think again. Sustainability.

• While food systems could address disability-adjusted life years due to chronic hunger, population pressure and climate change will make it much worse, particularly for sub-Saharan Africa. American Journal of Clinical Nutrition.

And that’s all she wrote folks. See you soon.

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…

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%!

Food Bytes: February 10th Edition

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

2020 is off and running and the world finds ways to fill in the gaps it makes.

There is lots of interesting stuff being published or planned for publishing in the food systems space.

There are new journals out there. Nature Food released its inaugural issue called “silos and systems” (with a corn silo on the cover) and it is really great so far. Highly recommend reading it - all open access articles to boot! While it has been around about two years, Nature Sustainability is high-quality and publishes a lot on food systems. Colleagues at Cornell are working with the Journal to come up with evidence-based innovations across food supply chains ready for scale-up. More on this project can be found here. The prestigious Cell Journal now has a sister journal called “One Earth.” While it focuses on climate and earth sciences, there are lots of food gems in each issue thus far.

I am also serving as the Editor in Chief of the Global Food Security Journal. We publish:

1. Strategic views of experts from a wide range of disciplinary perspectives on prospects for ensuring food security, food systems, and nutrition, based on the best available science, in a clear and readable form for a wide audience, bridging the gap between biological, social and environmental sciences.

2. Reviews, opinions, and debates that synthesize, extend and critique research approaches and findings from the rapidly growing body of original publications on global food security and food systems.

I am also serving as an Associate Editor of Food Systems and the Environment for the American Journal of Clinical Nutrition. We published our 10-year vision. In that, we highlight that the Journal will be soliciting cutting-edge papers that disentangle research that spans food system activities and actors, environmental change, and health and nutrition outcomes, taking into account the rapid socioeconomic, political, and societal transitions in the 21st century. The research space is complex and requires a convergence of new disciplines to understand the benefits and trade-offs of evidence so vital to improving diets and nutrition. We are looking for agriculture, food value chains, climate, environment, and diet themes to come together to answer the many evidence gaps that impact nutrition and human health.

The Lancet series on the double burden came out in late 2019 basically showing that there is a significant increase in low- and middle-income countries struggling with both undernutrition and overweight and obesity. The second and third papers on the etiology and actions to address the double burden stand out.

There is some controversy brewing in the nutrition world. But what else is new? JAMA published a pretty scathing article about conflicts of interest stemming from the series of articles that meat is actually not detrimental, or at least, neutral for health. JAMA argues that another group of scientists basically bullied the journal into retracting the articles, which did not happen. The JAMA called it “information terrorism.” What a mess.

A few of us from GAIN and Johns Hopkins University presented the Global Food Systems Dashboard at IFPRI last week. Check out the video and highlights here. The Dashboard brings together extant data from public and private sources to help decision-makers diagnose their food systems and identify all their levers of change and the ones that need to be pulled first.  Follow updates and announcements of the official launch on Twitter.

The co-existence of obesity and hunger in America

This is a re-posting from The Bloomberg Opinion.

The U.S. is notorious for its weight problem. With just 5% of the world’s population, it’s home to 13% of the world’s overweight and obese people. Roughly two-thirds of adults in the U.S. are overweight or obese and, even more alarming, 38% of boys and girls ages 10 to 14 are.

On first glance, these numbers seem to reflect overabundance — Americans have more food than is good for them. But the problem is more complicated than that, and worse: Many of the same people who struggle with extra weight also regularly go to bed hungry. That may sound like an impossible contradiction, but dig deeper, and it quickly becomes clear how hunger and obesity are related. Both are often rooted in poverty.

Percentage of obese adults in the U.S. (obesity = body mass index of more than 30). Source: The State of Obesity

Nearly 12% of American households are, by Agriculture Department standards, “food insecure” — meaning they have difficulty buying enough safe and nutritious food to meet their household needs. That amounts to roughly 40 million people, including some 540,000 children who experience very low food security. Food insecurity tends to be highest among Hispanic and black non-Hispanic families, and of course among unemployed and poor households.

Food insecure adults in the U.S. are 32% more likely than others to be obese — especially if they are women, one study found. Another revealed that children living in food insecure households have a greater-than-average tendency to be overweight or obese, and have poor eating habits. Other studies suggest that food insecure children also tend to display significant behavioral problems, disrupted social interactions, poor cognitive development and marginal school performance. These challenges, in turn, increase their risk of becoming obese adults.

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.

Food-insecure and low-income families face unique challenges that impair their ability to consume a healthful diet and maintain an ideal body weight. Their lifestyles tend to be sedentary because of their built environments, and their food tends to be served in large portions. The relatively inexpensive, calorie-dense food at their immediate disposal often lacks the nutrients needed for optimal health. As a result, though they may follow a nutritious diet for short periods, these are punctuated by cycles of financial and personal stress that lead to food deprivation, overeating, limited access to health care, reduced opportunities for physical activity and greater exposure to unhealthy food environments.

How can such cycles be minimized? It will take a concerted effort from many actors. The U.S. Congress, for one, should increase funding for the Supplemental Nutrition Assistance Program — food stamps — on which 50 million American families depend. And it should shift agriculture subsidies away from their heavy focus on corn, soybeans and other Big Ag crops and toward the farming of fruits, vegetables, nuts and legumes.

Local food banks, an important resource for food insecure households, deserve the support of citizens and communities, and should be encouraged to provide more fresh foods and fewer processed foods high in salt, sugar and unhealthy fats.

Employers can help, too, by providing mental and physical wellness programs, as well as discounts and subsidies for physical activity programs. These investments are inherently worthwhile, because employees who exercise tend to have better concentration and work output.

Finally, hospitals and health clinics can help working households provide healthy meals by creating what are called prescription food programs: Hospitals provide a set amount of money for each patient household, or a prescription that can be redeemed for nutrient-rich foods, including fruits and vegetables, in participating nearby markets or grocery stores.

The goal for governments, health-care providers and community groups should not be limited to building more markets in neighborhoods that now lack for healthy groceries. It’s also essential to encourage more community gardens and farmers markets, subsidize healthy foods, promote nutritious food choices, and ban  junk food advertisements to children. Fighting against obesity and hunger is a matter of fighting for basic food security — even here in the U.S.
