But I’m Over That Now

I usually don’t take a vacation in the summer because of the expense and the crowds, but I went against the grain, and we took a trip to America’s great western expanse. My partner and I spent many years growing up in the West, and it has always been a place that resonates in our genes. Our holiday started in Santa Fe and the four corners, and then onto California: Santa Barbara, Pismo Beach, Solvang, and then a long stint in Los Angeles. Compared to the east coast, you just can’t beat the nature that the West has to offer. We had our fill of hiking and oceanscapes, plenty of wildlife (Humpbacks! Coyotes! Pelicans!), and great seafood and Mexican food. We tried as much as possible to travel without relying on a car (I recommend the sleeper Amtrak from Albuquerque to Los Angeles), but it wasn’t easy.

Maybe Jim Morrison was right in that “the West is the best” back in 1965, but it hasn’t held up. My partner’s blog says it all. We always thought we might return to live on the West Coast, but our vision of what we think California should be is over, finished. It went in another, less interesting and unauthentic direction long ago. As Farhad Majoo wrote, “It’s the end of California as we know it. I don’t feel fine.” But I’m over that now. As you can surmise from some of my past blogs, I think I’ll just stay right where I am.

On the trip, I read a few books that resonated well with the Western scenery. The first, The Nutmeg’s Curse: Parables for a Planet in Crisis by Amitav Ghosh, who wrote the book during the most constraining lockdown period of the COVID-19 pandemic and the rise of the Black Lives Matter movement, will leave you spent, sad, and seething. He begins by describing how the colonial forces of the Netherlands, under the guise of the Dutch East India Company, purposefully and systematically eliminated the indigenous peoples living in the Banda islands, an Indonesian archipelago, to monopolize the nutmeg trade.

He further discusses the historic brutality of colonists on different landscapes through a process called “terraforming” and how that long history has contributed to the climate crisis we face, some disproportionately. He relates this genocide of the Banda people to other peoples, like the Western colonial forces in North America that obliterated Native American tribes and their way and essence of living. I was reading this book as we drove through the beautiful Navajo Nation. Witnessing places like Monument Valley and Canyon de Chelly leaves you awestruck, wondering, who deserves to watch over this land for all of us and future generations? They do.

Driving through their vast lands was devastating and inspiring, and I kept thinking about how this landscape is, at the same time, untouched and brutally altered. The Ken Burns’s documentary, An American Buffalo, punctuates how much has been forcibly taken from the Indigenous Peoples of this land. The Native Peoples. If you do watch the documentary, which I highly recommend, be prepared to be heartbroken over the long, dark history of “how the West was won.” As Dayton Duncan wrote in the New York Times:

“The story of what happened to the buffalo was a triple tragedy: for the animals, who were mercilessly slaughtered by the millions to feed an insatiable industrial demand for their hides; for the vitality of the Great Plains ecosystem that depended on them; and perhaps most profoundly for Native people, who were simultaneously dispossessed of their homelands, confined to reservations and deprived of the animals that had fed their bodies and nourished their spirits for untold generations.”

I also read Sea of Cortez by John Steinbeck and Rachel Carson’s The Sea Around Us. Both books were written in 1951 but still resonate with the perils of oceans today. Carson’s book was part of an ocean trilogy, and in this book, she dug into the science to help untangle the mysteries of the deep oceans. She mentions how the world was getting warmer, and sea levels were rising, but both were part of a “normal” process. Little did she know what was coming... I wouldn’t recommend them unless you like reading historically about what knowledge we knew then, as compared to what we know now.

On our holiday, I spent much time staring at the great Pacific Ocean – its vast blueness, mystery, and fierceness. While these books are a bit on the old side, it is fascinating to read how both authors were meticulously describing what we knew about oceans at that time. I still feel we know too little, and interestingly, many of us who work on food systems pay little attention to oceans. Instead, we spend a lot of time focusing on the land. This is ironic, being that land covers only 29% of the earth, whereas water covers 71%.

Yet, oceans and waterways matter a lot for food security. According to FAO, in 2022, the world produced 185 million tons of aquatic animals, and the net worth of the trading of aquatic food products was $195 billion. Even more so, 62 million are employed in the sector. This industry is nothing to sniff at!

Interestingly, in the past couple of years, aquaculture surpassed capture fisheries for the first time, contributing 51% of total fish production. But we have to figure out how to ensure both aquaculture and fisheries are managed in environmentally sustainable ways, and we must begin to care for our oceans and waterways if we want to ensure we have a rich biodiversity of blue foods in the future. My colleagues Roz Naylor, Safari Fang, and I wrote a paper reviewing six countries’ aquaculture policies and what could be learned from them. In these case studies—covering the EU, Bangladesh, Zambia, Chile, China, USA, and Norway—we highlight the need to find the right policy balance between semi-subsistence farms, small and medium enterprises, and large-scale commercial operations, particularly in low-income settings. The cases also highlight the importance of addressing aquaculture disease pressures and misuse of antimicrobials in many parts of the world and the challenges of establishing nutrition-sensitive aquaculture policies and incorporating aquaculture directly into food policy and global food system dialogues and action.

While in California, I ate plenty of blue foods, especially bivalve foods. Oysters, clams, crabs—you name it, we ate it. Did you know Pismo is the clam capital of the world? Bivalves are delicious, nutritious, and environmentally sustainable. I got my fill, and now I can go home.

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

 

It is hard to find the time to read, let alone write about what you read. One of the things about reading scientific literature is that you have to weed through many journals’ tables of contents to find the nibbles and nuggets that are worth your time. Sometimes, you get lucky and find some gems; other times, you don’t get further than the abstract. Regardless, if you don’t have LinkedIn or X, spoon-feeding your biased and “like-minded lemur” content, the never-ending search for quality papers is laborious and time-consuming.

Enter documentaries and podcasts. I find myself more and more listening to them to get a synthesis of a topic or a deep dive into an issue or scientific discovery. There is no shortage of food podcasts, but most focus on cooking and gourmandery. But a few goodies discuss the politics of food and the history of food. I try to add them to the Resource section of The Food Archive. I found this particular episode of the podcast, “What You’re Eating,” fantastic on the confusion of egg labels. The host lays out the issues and clarifies where your eggs come from and how to understand the labels on those confusing cartons better.

Two food documentaries worth the watch are Poisoned and How to Live to 100, Wherever You Are in the World. Let’s take Poisoned first, about how “unsafe” the U.S. food supply is, although often touted as being one of the most secure. The documentary starts with the contaminated burgers from Jack in the Box, which killed and sickened a slew of people. After lawsuits and regulations, getting sick from E. coli-contaminated hamburger meat is hard now. It shows that it works once governments can set their mind to something and put in strict and enforced regulations. Enter vegetables. After watching the show, I am not sure I will ever eat romaine lettuce again…much of it is grown right next to concentrated animal feed operations (where beef is raised in the U.S.). The manure runs off into waterways,  and the water from those said waterways irrigates the nearby lettuce crops. And then bingo! You’ve got severe contamination issues. It is worth watching to understand how food is produced in this country, how it is regulated, and how you can be safer with food in your kitchen.

How to Live to 100 is hosted by Dan Buettner, who wrote Secrets of the Blue Zones. He has been studying why, in some places, people live such long lives – sometimes beyond 100 years. He travels to Okinawa, Japan; Ikaria, Greece; Sardinia, Italy; Nicoya, Costa Rica; and Loma Linda, California — where more people live significantly longer than average. He summarizes some of their secrets to longevity into four basic mantras. Keep in mind these populations all get to their winter years in different, contextualized ways, and it is never that straightforward why someone lives a long life and others die too early. Dan argues these four lifestyle changes help:

  • Make movement a habit

  • Have a positive outlook

  • Eat wisely

  • Find and connect with your tribe

There are a lot of valuable lessons in this documentary (sans Dan showing himself riding his bike for 1/3 of the docuseries. Why do documentarians always have to show themselves so much? I digress…). One lesson is that no matter how long you live, you can live your best life and one of high quality. A lot of that centers around food. And wine. Yay!

The NY Times Magazine had two fantastic articles last week. David Wallace-Wells wrote a piece on the financial responsibility for climate change and how difficult it is to figure out the historical tally of damage. The price of historical emissions and removing carbon would cost $250 trillion. The U.S. alone has accrued a climate debt of $2 trillion. By 2100, $100 trillion. This shows how daunting it will be to turn around the damage we have done and will continue to do without serious action on climate change.

Another NY Times Magazine article focuses on young migrant kids from Central America who work night shifts in slaughterhouses – a dangerous, low-paying job – with very little compensation or legal status. They are often too tired when they get to school after working long, laborious hours all night, and often, they get maimed, injured, or exposed to terrible toxins that stay with them for a lifetime. It is a tragic story but so important to read to understand why younger kids and teens are trekking up to the U.S., what they face along the way and when they get here, and the fine line to ensuring their freedom. While it seems we have come a long way from the days of The Jungle, written in 1906 by Upton Sinclair of the Chicago slaughterhouses, this article makes you pause. Your heart will break for Marcos Cux.

And for some self-promotion, my team and colleagues published a few papers in the last six months that may be of interest to Food Archive readers:

  • Challenges and opportunities for increasing the effectiveness of food reformulation and fortification to improve dietary and nutrition outcomes: This article is about how reformulation and fortification face numerous technical and political hurdles for food manufacturers and will not solve the issues of increased consumption of ultra-processed foods. You can’t make junk food healthier at the end of the day…

  • Harnessing the connectivity of climate change, food systems, and diets: Taking action to improve human and planetary health: This paper presents how climate change is connected to food systems and how dietary trends and foods consumed worldwide impact human health, climate change, and environmental degradation. It also highlights how specific food policies and actions related to dietary transitions can contribute to climate adaptation and mitigation responses and, at the same time, improve human and planetary health. While there is significant urgency in acting, it is also critical to move beyond the political inertia and bridge the separatism of food systems and climate change agendas currently existing among governments and private sector actors. The window is closing and closing fast.

  • A global view of aquaculture policy: This article shows that government policies have strongly influenced the geographic distribution of aquaculture growth, as well as the types of species, technology, management practices, and infrastructure adopted in different locations. Six countries/regions are highlighted – The EU, Bangladesh, Zambia, Chile, China, USA, and Norway. These case studies shed light on aquaculture policies aimed at economic development, aquaculture disease management, siting, environmental performance, and trade protection. 

  • Riverine food environments and food security: a case study of the Mekong River, Cambodia: Rivers are critical, but often overlooked, parts of food systems. They have multiple functions supporting the surrounding communities' food security, nutrition, health, and livelihoods. However, given current unsustainable food system practices, damming, and climate change, most of the world’s largest rivers are increasingly susceptible to environmental degradation, with negative implications for the communities that rely on them. Rivers are dynamic and multifaceted food environments (i.e., the place within food systems where people obtain their food) and their role in securing food security, including improved diets and overall health.

Food Bytes: March 2023 Edition

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

So much going on in food and nutrition these days that it is hard to keep up. In looking at what has been published in the last month, three areas dominate ultra-processed foods, climate change, and blue foods. Let’s take each and highlight the latest and the greatest.

Ultra-processed foods: What are ultra-processed foods (UPFs), may you ask? Basically, junk food. But we scientists have to come up with fancy terms and categorize everything. UPFs are a very broad category of foods that generally are made from highly processed, industrialized ingredients not found in the home or in restaurant kitchens. These foods are designed to be hyper-palatable, often conveniently ready-to-eat, shelf-stable, transportable, strongly marketed, and, ultimately, highly profitable. More and more research shows that these foods are detrimental to various health outcomes (obesity, diabetes, cancer, morbidity, mental health, etc.) and could be potentially addictive and environmentally destructive. California, which always leads in food governance (blame it on the hippies), is growing worried about what exactly these foods contain. They are considering banning a number of staple ingredients found in these foods. I cannot even begin to source the sheer amount of literature coming out demonstrating the impact of these devilish foods, but here, here, and here are a few good systematic or meta-reviews. This Wired layperson article is a good summary. If you want to read two people who lead in the science of UPFs, read Carlo Montiero or Kevin Hall. Regardless of all the science coming out, their sales are increasing across almost every region of the world. Why? Well, they are cheap, have a long shelf life, are easily stored and transported for long periods of time, and are damn tasty.

IPCC AR6 Synthesis Report, 2023: Key Summary Figure

Climate and food: Hard too to keep up with everything going on. The most significant update is that the Intergovernmental Panel on Climate Change, also known as the IPCC, has come out with a synthesis report on how much time we have left before the world falls apart. They are surprisingly and cautiously optimistic, arguing that there is still time to address climate change before things start “gettin’ hot in here.” Food is heavily featured in this synthesis report, thanks to our AgMIP friends at Columbia University. They argue that food security and nutrition are and will continue to be significantly impacted, particularly in resource-constrained settings and among smallholder farmers. They also offer a range of mitigation and adaptation strategies, including agriculture, forestry, and other land use (AFOLU) options with reduced deforestation in tropical regions, shifting to sustainable healthy diets, reducing food loss/waste and intensifying sustainable agriculture (they even mention urban ag!).

When I asked Google’s new AI system, Bard, what was the latest science published in “food systems” in the last week, this is what they spit out:

Here are some recent research on food systems:

  • A new study found that the global food system is responsible for about one-third of all greenhouse gas emissions. The study, published in the journal Nature, found that the food system's emissions are mainly caused by the production of meat and dairy products, as well as the transportation of food.

  • A new study found that the global food system is also responsible for about one-third of all water use. The study, published in the journal Nature Water, found that the food system's water use is mainly caused by the irrigation of crops, as well as the production of meat and dairy products.

  • A new study found that the global food system is also responsible for about one-third of all land use. The study, published in the journal Nature Land, found that the food system's land use is mainly caused by the production of crops, as well as the grazing of livestock.

These are just a few of the recent research on the global food system's impacts on the environment. The food system is a major contributor to climate change, water pollution, and land degradation. These impacts are likely to become more severe in the coming years, as the global population continues to grow.

Not too shabby, but a bit outdated (and they don’t provide any citations). Interesting how AI is set to become such a game-changer, and yet, as an expert, asking Bard to do a bit of research, it is pretty generic and lacks scientific nuance, which can be dangerous…Here are some even more recent papers out this week on food systems and climate from a flawed human perspective:

  • Ivanovich and colleagues at Columbia University (see a pattern?) published a paper in Nature showing that if we continue on our current food consumption patterns, this will add 1 °C to an already warm planet by 2100. Most of this warming is driven by what is called high methane foods (methane is another toxic greenhouse gas) like livestock, dairy, and rice (yes, we cannot blame it all on those cute cow creatures). If we made some of the changes mentioned in the IPCC report above, we could cut 55% of that warming.

  • Another paper, again published by Columbia University peeps (they are on a roll), called for more studies to better show how the food security of households and communities is impacted by climate-related shocks. They argue that most studies only examine food production and availability, not access or utilization.

  • And last, and this is self-promotional, a few of us put together an analysis trying to understand if the EAT-Lancet planetary health diet was adequate in nutrients (we didn’t look at environmental impacts or other health impacts, and we are not suggesting to do so). This particular analysis shows that the diet is inadequate in vitamin B12, calcium, iron, and zinc. The EAT-Lancet may not be happy with these results but this is what science is all about — debating on a level playing field, DISproving one’s hypotheses, and not being wed to ideologies. I am not sure right now that everyone at the so-called proverbial table looks at science similarly and instead holds fast to their worldviews, which worries me. But a lot is at “steak.” The EAT-Lancet Commission part has been downloaded over 6,000 times in 4 years. That is pretty insane. So to go against that, dissect it, calls to do it better next time around, or at least look carefully at the data, in which multiple people analyzing the dataset, is, well, what science and the pursuit of truth is all about. But putting one’s arm out to be potentially severed. Bottom line: This paper is about the trade-offs that are par for the course with a grand food systems transformation.

Showing tradeo-offs of policy bundles: Crona et al Nature 2023.

Blue foods: More and more, and this is long overdue, blue foods, aka seafood, aka aquatic foods, are getting more attention. The Blue Foods Assessment highlighted their importance from multiple angles - important contributors to a nutritious diet, some species’ environmental sustainability, their risk of climate threats, and contributors to livelihoods. Some fantastic articles have emerged recently, including a fantastic paper by Christina Hicks and colleagues examining the injustices associated with aquatic food systems. Another paper summarized the BFA around 4 policy objectives to help realize the contributions that blue foods can make to national food systems around the world: ensuring supplies of critical nutrients, providing healthy alternatives to terrestrial meat, reducing dietary environmental footprints, and safeguarding blue food contributions to nutrition, just economies and livelihoods under a changing climate. However, trade-offs always exist, just as above. The figure shows these — the question is, what trade-offs are we willing to live with? And last, on blue foods, the great Roz Naylor at Stanford published a policy landscape paper in Food Policy (thanks, Chris Barrett!) on aquaculture. I had the pleasure of working with her on this. Through a series of case studies, she presents a state-of-play on how aquaculture is playing out globally, and again, where those policy priorities elicit trade-offs that can be detrimental to the environment or nutrition. Check it out.
