Food Bytes: October 2022 Edition

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

It’s been a long while since I posted a Food Bytes edition, and so much has happened in the food space in the past year. First, a UN Food Systems Summit happened, but I remain quite unclear on what was achieved or what will come of the year-long work leading up to the event. Second, a devastating conflict between two breadbasket countries trudges on, putting food security concerns back on the geopolitical agenda. Third, extreme weather events, many related to climate change, unrelentingly warn us that our ability to feed a world of 8 billion (yikes) is precarious and precious. But science is there to nudge us, generating new knowledge on why we and every other species are here, what accelerates us, what destroys us, and where we are heading. Charles Mann wrote in The Wizard and the Prophet (a stellar book about William Vogt and Norman Borlaug’s discordant visions to feed the world):

Another thing this book is not: a blueprint for tomorrow. The Wizard and the Prophet presents no plan, argues for no specific course of action. Part of this aversion reflects the opinion of the author: in our Internet era, there are entirely too many pundits shouting out advice. I believe I stand on firmer ground when I try to describe what I see around me than when I try to tell people what to do.

I resonate with these sentiments. Even though science is plagued by warts, hiccups, and flaws, catalyzing evidence and data to help describe the world matters because it helps us understand nature, people, and the planet. With that background in mind, this month’s Food Bytes is all about highlighting the science community’s observations and uncertainties of a changing world and what it means for food systems and climate change. I purposely do not highlight the work of my team and collaborators, but if you are curious about when we do, you can look here.

Let’s get the dark stuff out of the way. A paper by David Armstrong McKay and colleagues updated data showing that holding at 1.5°C will trigger multiple climate tipping points. What are these tipping points? Things like ice sheet “collapses,” forest “diebacks,” and permafrost “abrupt thaws” (see the figure to the right). These terms are downright scary but very plausible under different modeling scenarios. Okay, onto more uplifting news — KIDDING! Another study has shown that over the last 40 years, the Arctic has warmed four times faster than the rest of the world, also known as Arctic amplification. These are massive global shifts that will further warm the planet, creating all kinds of chaos. What does it mean for us wee creatures living in our humble abodes? Well, the news is not totally uplifting on that front either. We are and will be deeply impacted by climate — and no one is immune. Research by Sylvia Blom and colleagues showed that repeated, extreme heat shocks impact early child nutrition — both chronic and acute malnutrition. They show that in 5 West African countries, a 2 °C rise in temperature will increase the prevalence of stunting by 7%. As the two latest 2022 Inter-Governmental Panel on Climate Change Reports on adaptation and mitigation, also known as the IPCC, argue, we still have time to act, although when you read it, you may want to have a nice glass of scotch in hand. While the window remains open, it is closing, and fast. We need to make massive changes to the way we live, much of that involving our use of resources. A recent Nature Sustainability paper showed that no country meets basic needs—such as nutrition, sanitation, and access to electricity—for its citizens at a globally sustainable level of resource use. To meet needs, we need to use resources somewhere between 2-6 times more to meet everyone’s needs. Gulp. Just take a look at the difference between the United States (a) and Sri Lanka (b) in the figure below. Blue wedges show social performance relative to the social threshold (blue circle), whereas green wedges show resource use relative to the biophysical boundary (green circle). The blue wedges start at the center of the plot (which represents the worst score achieved by any country), whereas the green wedges start at the outer edge of the blue circle (which represents zero resource use). Wedges with a dashed edge extend beyond the chart area. Ideally, a country would have blue wedges that reach the social threshold and green wedges within the biophysical boundary. Look at the inequities comparing the two countries!

The research and science in understanding the impacts of climate change on food systems and vice versa are growing exponentially. It is hard to keep up with the literature and weed out the noise. One area that deserves more attention is the impact of food trade on global greenhouse gas emissions and the environment—particularly land-use change—a significant source of emissions coming from food and agriculture. A study showed that 27% of land-use emissions and 22% of agricultural land are related to international trade (2004-2017)—food products consumed in a different place from where they were produced. The largest land-use emission transfers come from Indonesia and Brazil to China, the U.S., and Europe. A PLoS paper examining the future of trade shows that if we keep managing and governing global trade as is, food systems will be misaligned with dietary health and sustainability outcomes.

Perhaps one solution is through changing agriculture subsidy policies. The UN Food and Agriculture Organization (FAO) published their annual SOFI report and highlighted the need to transform agriculture subsidy programs around the world towards those that generate and produce healthier food products. Marco Springmann at Oxford modeled the impacts of subsidy policies that focused on nutritious foods and found multiple benefits across both environment and health. I am really uncertain about the political appetite to change subsidies. Talk about vested interests… Speaking of priorities, Ben Davies and colleagues argue that making big transformative policy changes across food systems is wonderful, but don’t do it “on the backs of the rural poor.” Although there are 2.7 billion people engaged in small-scale food production and 1.1 billion people concomitantly living in extreme poverty while working in agriculture, they are often ignored in the “transformation” story.

Affordability of a healthy diet grouped by five different food system typologies, showing transition of food systems. Source: Ambikapathi, et al Nat Food 3, 764–779 (2022). https://doi.org/10.1038/s43016-022-00588-7

Positive transformation of food systems is not easy as history suggests. As Ramya Ambikipathi shows in a recent Nature Food paper, food systems have shifted from predominantly rural to industrialized and consolidated systems. Historically, incomes have risen faster than food prices as countries have industrialized, enabling a simultaneous increase in the supply and affordability of many nutritious foods. Evolving rural economies, urbanization, and changes in food value chains have accompanied these transitions, leading to changes in land distribution, a smaller share of agri-food system workers in the economy, and changes in diets. While the affordability of a recommended healthy diet has improved over time, food systems overall are falling short of delivering optimal nutrition and health outcomes, environmental sustainability, and inclusion and equity for all. Another fantastic paper by Jeff Waage and colleagues in Lancet Planetary Health shows the complex and risky relationship between agriculture and infectious disease, particularly in low-income and middle-income countries that are undergoing rapid food system transitions. They remind us that lessons can be drawn from COVID-19 and the rise of zoonotic spillover events within food systems should be prioritized (and minimized) on the political agenda.

Ensuring that everybody gets access to and consumes a healthy diet will remain a global challenge. The metrics, indicators, and data in understanding what people eat and why are improving. Just check out the Global Diet Quality Project, which collects dietary quality data in the adult population across countries worldwide using the Gallup poll and provides tools to monitor diet quality within countries. Wow. I hear rumblings of a global report coming out soon, so stay tuned. There has been a whole range of papers coming out on diet quality. Victoria Miller at Tufts University is on a roll. In one recent Nature Food paper, she examines diets across 185 countries from 1990 to 2018 using the Global Dietary Database (estimates and modeled). Their assessment shows that diet quality is modest at best but varies significantly depending on where you live, how old you are, and how much education you have. No surprises, but good to see more data emerging from this database. Miller and colleagues also published a more specific paper examining the consumption of animal-sourced foods worldwide showing that meat consumption is lower or higher than optimal intakes depending on the population. Another Miller paper published in JAMA examines the association of specific dietary factors with coronary heart disease, stroke, and diabetes using a systematic review. The table below summarizes the relative risks of the associations of nutrients with heart disease and diabetes events. Bottomline? Eat your fiber.

Another emerging area gaining significant traction with scientific consensus is ultra-processed foods (UPFs), a term loathed by the food industry and a handful of nutritionists. The majority of those working in nutrition epidemiology and public health largely agree that UPFs—food-like substances extracted from foods, such as fats, starches, added sugars, and hydrogenated fats that also contain additives like artificial colors and flavors or stabilizers—are detrimental to human health across a bolus of outcomes. Many people argue that these foods should be regulated, avoided, and minimized in the global food system. If you want to hear more about this ongoing debate, check out this BBC podcast and this online debate with some heavy hitters in the space like NIH’s Kevin Hall, Marion Nestle, and Mike Gibney. The next frontier for these foods is their environmental impact. While a handful of papers argue that these foods have a significant environmental and climate footprint, the evidence is scant, and much more needs to be done in this space.

The question is, are alt-meats in this category? The pace of science in this space is hard to keep up with as there is a lot coming out in the grey literature (see the IPES report and the OECD report as examples) along with peer-reviewed publications, but some of what is available often bends towards ideology and less science. Same with plastics. There is deep concern about microplastics showing up all over the place, including food, but the evidence and impact of these plastics on health outcomes need much more exploration. So while Mr. McGuire told Ben in The Graduate, that the future lay with one word, plastics, we may need to re-examine that advice in light of the fragility of our world.

Custodians of our memories

If you want to read a food book this year, read Eating to Extinction: The World's Rarest Foods and Why We Need to Save Them by BBC food journalist Dan Saladino. The book is about the rich biodiversity found around the planet and how humans have used that biodiversity to feed the world's population. Saladino illustrates how important this diversity is for our nourishment and sustaining the vast cultures and traditions that humans have passed on from one generation to the next. Not only is Saladino a wonderful storyteller, but the story he is telling is one of the most important in food systems today. He writes:

"We cannot afford to carry on growing crops and producing food in ways that are so violently in conflict with nature; we can't continue to beat the planet into submission, to control, dominate and all too often destroy ecosystems. It isn't working. How can anyone claim it is when so many humans are left either hungry or obese and when the Earth is suffering?"

Saladino structures the book across the main food groups — fruits, vegetables, grains, cheese, meat, seafood, alcohol, stimulants (coffee and tea), sweets, and wild foods. He discusses the importance of these food groups and their role in food security. He provides us with lush, visceral vignettes of particular places, exceptional people, and distinctive cultures uniquely trying to grow, raise, and nurture certain traditional varieties of these foods. You get a glimpse of how the hunter-gatherer Hadza hunts for honey in Tanzania. You learn how sheep meat, known as Skerpikjot, is preserved in the fragile ecosystem of the Faroe Islands. You feel the pressure of how Sicilians grow the vanilla orange amid the weight of the Cosa Nostra. You sympathize with the Syrians amid a protracted conflict who attempt to preserve their traditional sweet, Halawet el Jibn, made of war-threatened ingredients like pistachio. You realize that winemaking began in Georgia using traditional pots, known as Qvevri, a practice not done anywhere else in the world.

These stories are wonderful, but they are punctuated with startling and tragic statistics:

• 50% of all our seeds are in the hands of 4 companies.

• Of the roughly 6,000 different plants once consumed by humans, only nine remain major staples today.

• Three crops—rice, wheat, and corn—provide 50% of all our calories.

• 70 billion chickens (of roughly the same breed and ironically named "chicken of tomorrow") are slaughtered annually.

• 30 million bison roamed the great plains of the United States, all to be decimated at the hands of the white settlers.

• 95% of milk consumed in the United States comes from a single breed of cow.

• 90% of soybean grown in North and South America is genetically modified.

• 50% of all the world's cheese is made with bacteria or enzymes made by one company

• The giant Pacific bluefin tuna is down 97%. Yes, 97%.

• Only 2% of farmers are African American.

• We only consume 2% of barley that is grown. The rest is used to make beer or fed to animals.

• Speaking of beer, 25% of beer is produced by one brewer.

You learn about the heroes, like Vavilov, who spent and gave their lives conserving and preserving precious seeds, specific varieties, preservations, and processing of foods as a way to say, "remember us." We were here. They were and are the custodians of the biodiversity across the planet. They are also the custodians of our memories and humanity.

As Saladino escorts you around the world, I imagined these vignettes being turned into a beautiful documentary demonstrating the vast diversity that exists on the planet—as humans, as foods, and as cultures. As Saladino expressed, we must embrace diversity in all its forms: biological, cultural, dietary, and economical. Having more diversity across the range of agriculture systems and landscapes is vital. Capturing all this diversity on film, as the book does, could be a way to preserve these moments, memories, and the history of it all. So, we never forget what we once had.

While the book is inspiring, every chapter ends with a common tragic theme – and I am not giving anything away because it is in the book's title: Extinction. You realize how fast these ways of life, these foods, these cultures, and traditions are disappearing. Our world and food systems are transforming at a speed that is hard to comprehend and capture, and the loss along the way is disturbing. There are many reasons for this extinction, but the major ones are agricultural change, loss of habitats, disease, economic forces, hangovers and continuations of colonization, and conflict.

As Saladino expressed, these endangered foods will not become the mainstay of diets, nor should they. But they have essential and assorted roles to play; if we don't use them, we will lose them. In reference to a chapter on O-Higu, a soybean grown on the island of Okinawa made into unique tofu, "O-Higu might be an insignificant bean. But to many Okinawans, after colonialism and occupation, its return feels like an act of resistance and a celebration of who we are." Many traditions in holding onto these foods are worthy; they involve intimate knowledge, special skills, and lots of care and labor. It is not a simple path forward.

Our world and food systems are transforming into a homogenized vat of staleness. For many, saving these foods and the biodiversity that makes up these foods and our diets is not worth the effort as we move through the world at warped speed. Some argue that this savior complex is romantic and precious, and we should instead focus on the potential for technology and innovation. Growth, growth, growth. Call me sentimental, but I worry about solely following this path and what is lost along the way.

Last night, I watched Chris Marker's visceral Sans Soleil film. In it, the narrator said something that sticks with me:

When filming this ceremony, I knew I was present at the end of something.

Magical cultures that disappear leave traces to those who succeed them.

This one will leave none; the break in history has been too violent.

I want to witness the traces. I want to remember. What is the point of living in this world without cultures and all the food that punctuates those cultures? We must, as global citizens, decide what kind of world we want to live in and figure out what is worth saving. To me, it is the whole lot. I want to save it all—every food, every human, every animal, and every piece of culture. This is what makes our world interesting. As Saladino said, "the Hadza remind us that there are many ways to live and be in the world." I am hanging onto my hopes that the incredible array of people curating these endangered foods will remain the custodians of not only our memories but of our food traditions for the future.

The mavens

Food is everywhere. You can find it in almost every store and street corner (whether someone can afford it is for another blog entry). There are food blogs, food podcasts, food documentaries, food travel shows, food cooking shows, food apps, food zines, food mags, food porn…I could go on and on. People tweet, post, and hyperbolize about food, and are watching more cooking than actually doing cooking. Go figure.  Food in and of itself has become entertainment. It is less about people eating healthy and spending quality time on preparing and sharing food, and more about bragging rights. It has become a vehicle for snobbery and status but also, social aggression and competition. In a New York Times piece alluding to food as high art, “Nobody cares if you know about Mozart or Leonardo anymore, but you had better be able to discuss the difference between ganache and couverture.”

Much of the mainstream food system writing and pontificating is from authors who do not have traditional training in science and instead are journalists or writers, some coming from the cooking/restaurant sector. Many chefs are now TV stars in their own right and authors of famous books—and not just cookbooks. Many of these writers act as advocates and have developed celebrity status personalities. They often write about nutrition issues in a more ideological sense, taking parcels of select data to tell their story. The debates on the health of organic foods, GMOs, and industrialization have all been written about: less on the science, more on a belief system of what the food system should ideally look like, but usually only does so for the few elite. They have become the mavens of the food world.

“Nutritionism”— a reductive understanding of nutrients as the key indicators of healthy food—has created much confusion for consumers, leaving journalists, such as Michael Pollan—author of the infamous Ominovores Dilemma—to feed the public digestible answers to the most vexing global food system problems. Pollan along with many other writers (think Bittman, Waters, Petrini, Andres) have effectively opened a new dialogue about food systems, how we (un)consciously eat food, and how the individual can not only eat healthier, nutritious foods but within a healthier food system as well. It took someone like Michael Pollan to distill the complexity of nutrition science into one, simple message that resonated with the public: “Eat food. Not too much. Mostly plants.” Many of these food journalists argue that the nutrition field and nutrition scientists have largely failed the global population, leaving people utterly confused and lost in the swampy, ultra-processed junk food abyss.

Pollan, who has now moved onto the world of psychedelics, further explained:

“In the case of nutritionism, the widely shared but unexamined assumption is that the key to understanding food is indeed the nutrient. From this basic premise flow several others. Since nutrients, as compared with foods, are invisible and therefore slightly mysterious, it falls to the scientists (and to the journalists through whom the scientists speak) to explain the hidden reality of foods to us. To enter a world in which you dine on unseen nutrients, you need lots of expert help. But expert help to do what, exactly? This brings us to another unexamined assumption: that the whole point of eating is to maintain and promote bodily health. Hippocrates’s famous injunction to ”let food be thy medicine” is ritually invoked to support this notion.”

Gary Taubes, a science writer/journalist, and low carb diet advocate argues:

“The 600,000 articles — along with several tens of thousands of diet books — are the noise generated by a dysfunctional research establishment. Because the nutrition research community has failed to establish reliable, unambiguous knowledge about the environmental triggers of obesity and diabetes, it has opened the door to a diversity of opinions on the subject, of hypotheses about cause, cure, and prevention, many of which cannot be refuted by the existing evidence. Everyone has a theory. The evidence doesn’t exist to say unequivocally who’s wrong.”

Tit for tat, scientists also poo poo on these journalists and find their prose problematic. First, some scientists argue that the Pollans of the world interpretation of science is filled with individual dietary purity. Their idea is to bring food systems back into one’s control, into one’s environment. This is such a difficult prospect for so many people around the world, particularly for those who are suffering from hunger or are struggling to make ends meet and have no voice, no agency. Second, some scientists call these food journalists “agri-intellectuals” who boast more about what should be considered healthy and sustainable production systems without a lot of thought about how farms really operate, and farmer families’ daily struggles, inequities, and the difficulties in earning a living growing food. And last, some find their writing just disconnected from reality and instead, drowning in Americana-centric, navel-gazing arguments with a lack of focus on the perverse political and structural systems that underpin how our globalized food supply is governed that can’t be unraveled by growing your own herb garden.

Norman Borlaug, the agronomist who was largely responsible for the Green Revolution in Asia and Latin America said:

“Some of the environmental lobbyists of the Western nations are the salt of the earth, but many of them are elitists. They've never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels. If they lived just one month amid the misery of the developing world, as I have for fifty years, they'd be crying out for tractors and fertilizer and irrigation canals and be outraged that fashionable elitists back home were trying to deny them these things.”

Yikes. I wouldn’t go that far Norman…but I see your point. I think…While Norman wasn’t referring to journalists per se, he was referring to lobbyists/advocates/policy wonks that also take the “I know what’s best” high road. The point is, while we scientists can complain all we want about who is shaping decisions and the psyche of the general public, we too need to get better at messaging. We need to be savvier at influencing. We need to use the evidence in ways that convince others to take action and make a change.

I wish I could write as convincingly as Pollan does. I truly do. Wouldn’t it be cool if journalists and scientists got together, shared science, ideas, and information, and wrote joint articles and books? The incentive structures would need to change, but the output could be powerful. Now that would be mavenizing!

Time To Invest in Food Systems Science

President Biden’s first budget request when he came into office called for significant investment to science with increased budgets to the National Institutes of Health (NIH), the National Science Foundation, NASA and the National Oceanic and Atmospheric Administration, and the NIH office funding research on climate change and human health. The U.S. Department of Agriculture’s budget alone would increase from $647 million to $4 billion to be spent on research, education, and outreach. This is a signal that science will no longer be swept under the rug.

On February 23, 2021, the World Food Prize Foundation released a statement penned by 24 of its Laureates—considered some of the world’s experts on food security—urging the Biden Administration to focus on alleviating hunger, poverty, and malnutrition around the globe. The Laureates called for investments to improve food systems—which feed us—but also are responsible for 30% of greenhouse gas emissions and the generation of diets that are linked to 6 of the top 10 risk factors of the global burden of disease. They urged the U.S. to strengthen and leverage alliances, play a leadership role in the upcoming United Nations Food Systems Summit this September, and refresh evidence-based policymaking. Others have called for the U.S. to transform the food systems as well including the Rockefeller Foundation and renewed engagement marking the 50th anniversary of the 1969 White House Conference on Food, Nutrition, and Health. Some, including academics and former U.S. senators and the Secretary of Agriculture, has gone further to aim for a “moonshot” federal funding for nutrition research.

Can we now please stop using the word “moonshot”?

One way to do that is for the U.S. to invest more in food systems science and research. As several of us wrote in a recent Global Food Security Journal piece, research has a vital role in charting a positive and sustainable direction for global food security, nutrition, and health. At a time when facts, science, and evidence are under ever greater scrutiny, and even openly disregarded as suspect by some political and business leaders (we won’t mention any of the very obvious names), the rigors of research have never been more critical. Research can and does bring about wholesale changes in attitudes, political thought, and action.

Those of us who do research must see their role in terms of knowledge generation and the translation of this knowledge into a form that is relevant to decision-makers in government, business, and civil society.

Those who design, shape, and enact policies need to access the research they need in a digestible and accessible way. Failure to achieve this brings a very considerable risk of being ignored. Researchers must learn to sit at policy dialogue tables not set for them, but the table for the users of their research – that is, the policymakers. It is a table that many researchers are not accustomed to sitting at.

Food systems encapsulate the choices we make about which foods to consume and grow and how we transport, store, process, and market them. These choices profoundly affect outcomes we care about.  To date, the choices all stakeholders make, whether governments, foundations, businesses, civil society, or individual consumers, have relied on fragmented information on food systems, of variable quality, which is difficult to access or use. 

The Food Systems Dashboard is an open-access data platform to address these issues. Created by Johns Hopkins University, the Global Alliance for Improved Nutrition, the UN Food and Agriculture Organization, and many other collaborators, it launched in June 2020, to attempt to boost the evidence-based decision-making on food systems. The Dashboard is designed to inform decisions that have positive effects on multiple social and environmental challenges simultaneously. Different food choices have different impacts on health, the environment, and livelihoods. There are trade-offs and synergies which need to be surfaced, navigated, and mitigated. For example, different foods have different nutrition values, greenhouse emissions, and different natural resource use implications. In short, the Dashboard is the beginnings of an ambitious “Google Map” for food systems. Let’s hope we make it as navigable and useful over the next decade.

Food systems must adapt and transform to deliver sustainable, healthier diets, and durable livelihoods without decimating the planet. Yes, that is a lot to ask! To do that, we need investment in science, evidence generation, and decision-making tools, like the Food Systems Dashboard, that enable data-driven decision-making in food systems. The Biden Administration has taken a bold step forward to invigorate the various fields of science in the U.S. In turn, the research community should rise to this challenge, and we provide a platform to challenge the status quo and take food system transformation in a direction we may have imagined but are far from realizing.

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: October 1st Edition

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

Its been a while since the last Byte. What can I say, COVID and all things America has got me down, slow to move and at times, speechless. So here it goes.

The Food Systems Dashboard was officially launched on June 1st and I think thus far, it is a useful tool. It brings together 170 indicators that characterize food systems, representing just about every country and territory on the planet. There are some snazzy ways to visualize the data or if you choose, you can just download the entire data set. Have at it and send feedback. Keep checking on it, because more features, bells, and whistles are coming soon.

The Global Panel on Agriculture and Food Systems for Nutrition published its new Report, Future Food Systems: For people, our planet and prosperity a few days ago. It’s chock-full of really good data with contributions from many stellar experts and scientists working on food system transitions and transformation. Plus, the cover is pretty badass.

Speaking of world order, or the lack thereof, a new book out of John Hopkins Press entitled “COVID-19 and World Order: The Future of Conflict, Competition, and Cooperation” is out. Project Muse was gracious enough to provide it as a free download. I contributed a chapter on food security. I recommend reading the last section of the chapter, “The necessity of world order for food security.” I am a bit harsh on the UN and CGIAR systems, but the COVID-19 response has displayed the weaknesses of the multilateral system and existing institutions. Many of these organizations are totally necessary but are perhaps now out of date and in need of an overhaul.

The High-Level Panel of Experts of the UN Committee on Food Security published a great paper on COVID-19 and food security. My guess is the very thoughtful Jennifer Clapp may have been a significant contributor. They lay out some scenarios of short to long-term impacts of the pandemic on food systems. Here is a quick diagram if you don’t have time to read the report. Basically, we are all screwed.

Food policy specialist Corinna Hawkes has a new blog series out entitled the Better Food Journey. Cool stuff. Check it out.

Are you getting sad? Brace yourself, because according to the World Wildlife Fund’s Living Planet Report, “Our relationship with nature is broken.” Sounds like a Werner Herzog documentary. They argue that because humans are the biggest instigators of nature’s destruction we should be the ones to fix it. Here here. Agreed. Too bad our current administration of the ol’ US of A doesn’t feel the same. And THAT is problematic for the whole world not just as dummie Americans or Californians, although “climate change is smacking California in the face.”

Let’s change the subject to one a bit more uplifting. Childhood stunting! In all seriousness, the American Journal of Clinical Nutrition just published a series on how countries can reduce stunting. They highlight some countries that have had success, and for those of us who work in nutrition, the usual suspects - Ethiopia, Bangladesh, Peru et al. But there are some good lessons to be had. Check out the supplement here. And for those more interested in the state of acute malnutrition, there is a good website of acute malnutrition data on over 20 indicators, including prevalence, incidence and coverage.

And for any of you interested in the UN Food Systems Summit slated for next year, keep posted on the latest news here. There will be a lot of activity leading up to the Summit. The question remains, will any of it matter for those being left behind living with hunger, food insecurity, and poverty? Or will it be just another global high-level meeting of the usual suspects? The jury is out…but I will remain hopeful.

Generating knowledge, dutifully and honestly

“Maybe working on the little things as dutifully and honestly as we can is how we stay sane when the world is falling apart.”

— Haruki Murakami

This quote by Murakami really speaks to researchers and scientists: Keep focused. Crowd out the noise. Discover. Be dutiful and honest.

But as Tony Fauci, head of the National Institutes of Infectious Disease of the United States gets the cold shoulder from our dear Potus, with attempts to undermine his evidence-based warning calls of a worsening COVID-19 pandemic here in America, it is hard to ignore the last part of that quote - the falling apart bit.

As researchers, we often keep our heads down and dig deep into the details with laser sharp focus to keep generating data and evidence for the greater good of science and knowledge. But we can no longer sit quietly behind our benches and laptops and blissfully hope that someone, anyone, will read that peer reviewed paper that you just published in Journal X. We need to be attuned to the political climate.

Speaking of publications, I was asked to contribute to an exciting, upcoming Johns Hopkins University Press publication COVID19 and World Order. In my piece, I make a series of technical recommendations on what it would take to achieve resilient food systems and potential measures to address our current pandemic and avoid catastrophic future zoonotic pandemics. I bring up this publication because none of the recommendations to fix food systems I made in the paper will stand on two legs with the current fractured and sclerotic global political enabling environment. In order for food systems to function effectively, equitably, and sufficiently during the pandemic and long after, the political environment must be one that embraces global cooperation and inclusion and minimizes political polarization and geopolitical competition. And we, as scientists and researchers, cannot remain silent, disengaging from the political process, however dismal it may be.

Politics matter for the world and for science, and now more than ever. Frank Fukuyama wrote: “Countries with dysfunctional states, polarized societies, or poor leadership have done badly, leaving their citizens and economies exposed and vulnerable.” It is not surprising that states led by populist, inward-facing leaders such as the United States, Brazil, and Mexico are not sufficiently addressing the pandemic. This has led to dire consequences for the citizens living in these countries with many who are struggling with food insecurity and high COVID-related morbidity and mortality.

The COVID-19 response has also displayed the weaknesses of the multilateral system and existing institutions. Within this, the “global food architecture” is often slow, outdated and needs 21st-century support and strategic know-how. One of those entities - the World Health Organization - has tragically and sadly just lost its support from the United States during a time in what may be one of the most crucial global health issues of the century. Multi-lateral cooperation looks perilous and science and the data that it bears is being undermined.

However, cooperation can happen in times of crisis - we have seen it before. Perhaps the UN Food Summit in 2021 can be a moment to create a global strategy for food governance that is nimble, modern, and inclusive, backed by an Intergovernmental Panel on Climate Change-like body that provides evidence and science to support actions.

As the Editor-in-Chief of the Global Food Security Journal, my co-editors and I share our perspectives on the food security challenges that face humanity and lay out our vision and call for stronger food systems research and science in the 2020s. I think this piece comes at a critical moment in food policy with COVID and climate change, because the challenges and opportunities for food systems research that lay ahead are significant, requiring that high-quality science be translated into policy faster than ever before.

“Our vision is one in which research and science, and the evidence stemming from their application, not only inform food and environmental policy, but are adopted and mainstreamed into actions at the national, regional, and global levels.”

In the paper, we write: “At a time when facts, science, and evidence are under ever greater scrutiny, and even openly disregarded as suspect by some political and business leaders, the rigors of research have never been more critical. It is also important not to become disheartened by the slow speed of change in policy and practice, even when the appropriate course of action is clear ‘to us.’ Research can and does bring about wholesale changes in attitudes, political thought, and action, but change takes time.”

We argue that the food systems have transformed, but with that transformation, we are left with profound and widening gaps to address sustainability and equity. These gaps will make future food security and continuity of life on the planet difficult to say the least. As researchers, we will have to fill in those gaps to ensure we meet the demands of a growing population sustainably while co-existing in amity with the planet.

We also need to find the stitched pockets of progress and small glimmers of hope as the basis of our knowledge to move forward - dutifully and honestly.
