Food Bytes: January 2025 Edition

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

Here in NYC, we are settling into a deep freeze. I sort of like it. The air is a bit more electric and crisper. Clean. Silent. And when the sun shallowly crosses over the landscape and warms you up a tad, you feel so grateful. For those of you, dear readers, who know how this archiver spends her time, I eat a lot of clams (note the header change on the Food Archive). This time of the year has some of the best bivalve eating. This archiver also spends time with her better half making dark and sad music as part of the Sound Furies. It seems that with each passing year, we get less and less snow on the East Coast. It reminds me of this tune we recorded in 2019, but my better half wrote the lyrics when he was young, living in northern California., sleeping in his ‘67 mustang.

last night it snowed though it's almost summer
it hasn't snowed here for 6 yrs
maybe it was the silence, like a blanket in the night
we don't know why we had this dream

Enough pontifications about weather and clams. Let’s get into this month’s Food Bytes. I always like to start the monthly round-up with a few recommended books I have been reading. Here we go. An Immense World by Ed Yong is a fascinating view of how animals perceive the world through their specialized and adaptive senses. Douglas Brinkley’s whopping 600-page read, Silent Spring Revolution, provides a historical deep dive into the beginnings of the environmental movement in the United States in the 1960s. He articulates how presidents and scientists charted a course for protecting the environment (it is my background homework for a book I am working on that I allude to here). This was a time when presidents were presidential (yes, even Tricky Dick is looking good compared to what we are dealing with now…) and worked to preserve the planet instead of watching it all burn. Delano by John Dunne (Joan Didion’s husband) is about the California grape strike led by Cesar Chavez and his sacrifices to ensure that migrant laborers get a fair shake. Again, this book is incredibly timely with the present-day shifts in U.S. “policies” to deport immigrants—the very same people who are keeping us well fed and food secure. And last is Rachel Kurshner’s short story collection, The Hard Crowd. She just oozes cool.

Book reading by the food archiver

Food and cooking

There has been a deluge of articles and media attention on ultra-processed foods. Let’s start with that and then get into real food stories.

The change in attribution of sugar-sweetened beverages to diabetes (T2D) and heart disease (CVD) incidence across regions from 1990 to 2020.

  • Ah the lovely world of ultra-processed foods (UPFs). These foods are high in sugars, salts, or unhealthy fats and have additional ingredients such as additives, preservatives, and many other hard-to-pronounce ingredients that make them taste good and allow them to sit on shelves for decades. Many scientific articles are trying to attribute UPFs to various deleterious health outcomes, and the evidence, while varying in quality, is building. Enough so that policymakers are taking note. Research suggests that almost 60% of the American diet comprises these foods. Yum. The New Yorker put out an article trying to understand why that is. It is a good read that tries to unpack the evidence. One thing that comes up is that not all scientists agree on the impacts of UPFs on health.

  • A Nature Food article delves into how governments have responded to regulating UPFs. Most government action has been on consumer education, mainly labeling food products rather than eliminating or regulating the companies that make these foods.

  • It is not only foods we are talking about. There are also ultra-processed beverages. Using the Global Dietary Database, this Nature Medicine paper shows that in 2020, 2.2 million new diabetes cases and 1.2 million heart disease cases were attributable to sugar-sweetened beverages worldwide. Between 1990 and 2020, the most significant increased attribution of these drinks to diabetes and heart disease was in sub-Saharan Africa! However, sales of these beverages, particularly soda, are rising (see the figure to the right). Great…

  • Onto real foods. I highly recommend this New Yorker article on the secret history of risotto and the rules that govern how to make this delicious dish whose origins sit on the Po River (a river very constrained by climate change).

  • Speaking of iconic foods and their origins, those who have lived in NYC for decades likely remember this Indian restaurant enclave in the East Village. You know, the one with all the Christmas lights. Well, in typical warp-speed fashion and the brutal world of restaurant ownership in this city, the Indian restaurant hubs have moved to other parts of Manhattan and, more so, Queens. But still, this one restaurant in the village keeps shining on. Funny enough, my former college roommate lived above this place in the late ‘90s. It is (not)safe to say she had a roach problem.

  • Then we have tortillas. I wish we had a tortilleria in our hood, but alas, we have to buy the Mission brand tortillas, which taste like cardboard. As this article in the Atlantic suggests, they have lost their magic.

  • Last, but not squarely in food, the Lancet published a commission to find ways to measure obesity better. With all the kicked-up controversy regarding body mass index as a sufficient measurement tool to delineate overweight and obesity, it’s good timing. Here is a nice infographic that summarizes their recommended diagnostic.

Climate change

Let’s move on to a lighter topic: climate change! In all seriousness, we are in a scary time. This past year, 2024, was the warmest year on record, and the average global temperature was more than 1.5°C above pre-industrial levels for the first time, with 11 months of the year exceeding 1.5°C. To make matters worse, the current U.S. administration has pulled out of the climate accord and plans to “drill baby drill.” This trend and these political decisions fuel our motivation to fight the good fight and ensure the world moves towards mitigation and adaptation solutions, with or without the United States.

  • The Economist published a well-balanced article on the potential and limits of technology to mitigate climate change through the livestock sector. It is nice to see the International Livestock Research Institute’s work (based in Kenya and Ethiopia) highlighted—who partner with some of the poorest in the world who are tending to animals for their livelihoods.

  • One issue is to ensure that those countries and populations struggling with undernutrition still have options and choices to consume animal-source foods, particularly in places where access is incredibly and unfairly limited. The Netherlands Working Group on International Nutrition and Clim-Eat put out a brief on animal-source foods in low- and middle-income countries that nicely summarizes the broad evidence. My only gripe is that they should cite the original peer-reviewed publications and evidence toiled over by scientists as opposed to the reports that summarize the said evidence.

  • Grist, a fantastic climate/environment/food reporting outfit, wrote a worrisome article about how many farmers and farm workers now need to work at night due to extreme heat. conditions Farming is already hard enough, and now this.

  • Speaking of great journalism, Civil Eats has summarized a set of articles of their “best climate reporting” of 2024. Check it out.

  • I have lots of time and space for Kyle Davis’s work. In this paper in Science Advances, he and colleagues use high-resolution data on forest cover in Nigeria and find that 25 to 31% of annual forest loss is linked to climate variability. They also find that changes to forest cover have positive associations with dietary diversity, whereas cropland expansion does not. There is much to think about adaptation-wise regarding how the world manages land and forestscapes.

  • I always have to throw in a critique of the EAT-Lancet Commission. In this paper by Klapp and colleagues published in the Lancet Planetary Health, they articulate a justified framework of shortcomings (see figure below) that the Commission did not address in the first report in 2019 with the hope that these issues will be taken up by the Commission when the 2nd report comes out in the fall of 2025. What I can say at this stage, Anna-Lena, is that we cover some, but not all, of these crucial issues. It looks like a third Commission may be in order!

Food Systems and Farming

Alignment between food system transformation and degrowth

  • This paper in Nature Food by Matt Gibson and some of my favorite colleagues Constanza, Daniel, and Mario (yay, Cornell!) presents a fantastic notion that in the political momentum that we must “transform our food systems,” there is also this notion that we have also to consider downscaling of excess production and consumption among high-income countries and overconsuming individuals. The figure to the right shows the alignment (or misalignment) between the goals and objectives of degrowth and food systems transformation.

  • But some argue that big farms don’t need a lot of transformation and should stay the course of how they are being managed. This article ruffled a lot of feathers. The title, “Sorry, but this the future of farming,” is snarky and reeks of know-it-allism. Anyone who comes to the farming conversation as having THE solution is suspect. This article is the last in the NYT’s series on “What to Eat on a Burning Planet” — a mix of low and high-quality articles with some half-truths. Go to the bottom of this article to see the series.

  • Let’s get to some farming articles. This paper in Nature Communications argues for the importance of including genomics research and development of what are called underutilized crops, but also called neglected crops or opportunity crops—into breeding strategies, cutting-edge research, capacity building, and representation that some major crops like maize, rice and what get.

  • A slew of experts published this paper in Nature Food to highlight the importance of small-scale fisheries (SSF). In this mapping exercise, they estimate that SSF provides 40% of the global seafood catch worldwide. This 40% provides roughly 2 billion people with 20% of their dietary intake of six crucial micronutrients. Half of these SSF are women, and many are employed in Asia. Africa supplies the largest catch. This is a fantastic article for those interested in blue foods.

  • I love this Soil Atlas that comes out each year by the Heinrich Boil Stitlung/EU. This report is chock-full of great case studies and figures arguing for better care and management of soils worldwide to promote resilient agriculture and mitigation of climate change. Called the global silent crisis,” 1/3 of soils are degraded globally, and 40% of those soils reside in Africa.

Self-promotion (sorry!)

I always have to be a bit self-promotional. The Food Systems Countdown Initiative (FSCI) has published its third annual paper in Nature Food and Policy Report. The highlights?

The FSCI interactive tool on the Food Systems Dashboard

  • Over the past two decades, meaningful progress has been made in improving food systems. Of the 42 indicators examined, slightly fewer than half (20) changed in a desirable direction from 2000 to 2022.

  • Most of the FSCI tracked food system indicators interact with other indicators, either directly or indirectly, meaning that change in any one area of food systems is likely to affect others and that unlocking change may require coordinated action across multiple dimensions.

  • Certain indicators related to governance and resilience are key leverage points — and could be critical because of their influence and dependence on other aspects of food systems, and change in them can affect many other indicators.

One cool thing we did was put the indicators and their interactions on the Food Systems Dashboard. You can play with the FSCI data in all kinds of ways. To get yourself oriented, you can find the indicators here, all the data globally and by country, the country profiles of the FSCI data (for example, Kenya), and last, the interaction tool (which is pretty neat).

We’re screwed, but some more than others. And that is not fair…

  • The scary annual World Risk Report just came out and it just got a bit scarier this year. Gee, I wonder why…we are so screwed.

  • Reuters published a heartbreaking collection of journalism entitled “Starving World.” Just devastating but worth taking the time to read.

  • With avian flu sparking and spreading, this article in Nature Reviews Biodiversity is a warning call about pathogens and planetary change.

That banks the river for which it's named

Rivers are special. These ribbon-like bodies of water cut through topography, shaping and shifting the landscape around them.

rivers begin where they end
if 1 considers rain + jet stream winds
look deeper into grainy sands
the sublimation from the wind-swept lands ever reach sea — Jordan, Sound Furies

My partner and I have always been drawn to rivers and try to live or be near them. We currently reside quite close to the great Hudson River (~500 km long), where we can amble through Riverside Park and enjoy the views. We are so obsessed with rivers that we made a double album as the Sound Furies dedicated to rivers, entitled “Tributaries.” One of my favorite songs from the album is Columbia.

We are not alone in our obsession with all things river. There are many songs inspired by rivers in the archives of rock-n-roll. Al Green just wanted someone to take him to the river. Jimmy Cliff had many rivers to cross. Joni Mitchell longed to have a river to skate away on. Sam Cooke was born by a river. Tina fearlessly rolled on a river (thanks for the original CCR). I could go on and on, but I think you get the point. Rivers mean something to many of us.

It is not just music. There are a plethora of movies about rivers. African Queen, A River Runs Through It, and one of the best movies ever made which spends most of its time on the river, Apocalypse Now. In the movie, the French woman living on the plantation says to Willard (played by Martin Sheen), “Do you know why you can never step into the same river twice?” Willard answers, “Yeah, 'cause it's always moving.” The best scene, though, is the conversation between Willard, who has come to assassinate the unhinged Colonel Kurtz (played by Brando). They converse about the Ohio river and a gardenia plantation.

What was up with all those movies in the 90s about dead bodies being found along river banks — Short Cuts, Stand By Me, A River’s Edge, and of course, David Lynch’s Twin Peaks? We Gen Xers were so demented.

Supposedly, there are 165 major rivers around the world, but no one really knows the real number. The five longest rivers in the world are the Nile, which starts in Uganda and moves north (odd, right?) to Egypt, the Amazon-Ucayali-Apurimac in South America, the Mississippi-Missouri-Red Rock in the U.S., the Yangtze in China, and the Yenisey-Baikal-Selenga in northern Asia. The Nile is the longest, topping out at 6,650 km. The Danube in Europe flows through 10 countries. The Congo River is the deepest. Rivers serve all sorts of purposes. They provide water, food, habitats, transportation, and recreation, to name just a few purposes. Rivers are really important for food. Fish and other aquatic creatures that live in rivers are consumed. Food is traded on and transported by rivers. Food is grown in or around river banks. Water from rivers irrigates crops.

We wrote a paper on the dynamism and multifaceted nature of rivers as 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. In the figure below, we showed the elements of multidimensional riverine food environments.

The paper nicely describes why river ecosystems are so critical. “Rivers can be described as nutrient highways across the earth’s surface, transporting sediment and water, sequestering carbon from the atmosphere, and connecting and storing immense biodiversity through aquatic life. The flow and transportation of sediment create environments for cultivation (e.g. rice farming), with river deltas being one of the world’s most agriculturally productive areas. Rivers support approximately 1/3 of all global food production, and an estimated 70% of freshwater from rivers is used for agriculture.”

There are so many challenges with rivers. The first issue is environmental: climate change, environmental degradation, and pollution are vastly changing these waterscapes - altering their composition and flow. The second issue is overfishing and overallocation, meaning the building of dams for electricity, are altering the riverine ecosystems and marine life and creating water shortages and river connectivity, respectively. As for rivers that cut across multiple countries, who governs these waters and decides who can build dams and where? We see those challenges in large rivers such as the Mekong — where China is building dams upstream impacting many Cambodian and Vietnamese living downstream. We also see this with the Nile, in which Ethiopia is building damns to electrify the nation, which could have massive impacts on irrigation systems for Egyptian agriculture. The third issue is that while rivers transport and contain food, they also bring other things, like diseases and unhealthy foods deep into river communities. This New York Times article discusses how the Amazong brought the COVID-19 pandemic into the far reaches of the Amazon forest.

The spread of covid in just a few months during the pandemic along the Amazon waterways. Source: NYT

“The Amazon River is South America’s essential life source, a glittering superhighway that cuts through the continent. It is the central artery in a vast network of tributaries that sustains some 30 million people across eight countries, moving supplies, people and industry deep into forested regions often untouched by road. But once again, in a painful echo of history, it is also bringing disease.”

The Amazon also carries highly processed foods. According to this article, multinational companies like Nestle had river barges that delivered junk foods to isolated communities in the Amazon basin.

There is also the issue of rivers flooding, damaging infrastructure and harming humans and animals in their way. And now, we are experiencing rivers above us — atomospheric rivers corridors of concentrated water vapor in the atmosphere that wreak havoc. What the hell?!

World WildLife Fund’s solutions for sustainable rivers

I can’t recommend enough the documentary “A River’s Last Chance,” about the Eel River. It delves into the history of how this river has been managed, or lack thereof. The Eel River is in Northern California and has been vulnerable to overfishing of its salmon, logging, floods, droughts, and dams. While the wild salmon population is trying to recover, new cash crops—weed and wine — threaten the salmon once more. It is quite a story of a river struggling to survive.

World Wildlife Fund has a fantastic initiative, Rivers of Food, in which they propose a four-pronged solution towards a more sustainable future for rivers and food security.

Let’s hope rivers can be saved as they provide a vital lifeline for nature, animals, and humans. They are also just so romantic and atmospheric. We used to dwell right near the Tiber when we lived in Rome. It was so magical. The way the early morning light hit the surface of the water, the banks, and the bridges. During the late summer months of the year, the starlings would circle around the Tiber, before settling in for the night in the treetops along the river banks. In Paolo Sorrentino’s La Grande Belleza, the early morning light on the Tiber is captured so beautifully below.

Ran my fingers across the world

On the eve of a new year, we are meant to reflect on all that we accomplished (and didn’t) and put forward our hopes and goals for the new year. I find this hard to do as I get older because time seems so warped, and change is hard to measure. When I reflect back to 2023 to see what has changed for me, I am left with blurry memories and vague recollections, much like the three years of living during the pandemic. But there were some bright spots and standout moments.

Our last New Year’s Eve was spent crisscrossing most of Italy, ending in the heel, also known as Puglia (where my family is from), with the idea that we wouldn’t return for a long while. Not that we don’t love Italy, but we spent almost six years living there, and maybe it is time to see other places if we do decide to travel. I had just learned I was granted tenure at Columbia University and would join the new Climate School faculty in July of 2023. Exciting. Now comes the hard part – we had to sell our house and downsize our belongings to snuggly fit into a smaller Columbia-subsidized apartment in NYC. Offloading a house in the middle of a housing crisis with high interest rates is stressful and borderline nightmarish, but we managed to do it. Plus, moving just sucks. No matter how often you do it (and for us, we are at 25 times), it is just a massive hassle. So, the first half of 2023 was one significant stressball transition phase.

Things fell into place once we got to NY in June. We live in the Upper West Side, where I have worked for a long time and where we have lived before, so it all seems routine and familiar. Are we too comfortable and normalized? God forbid that we get too comfortable. It may be time to move to another borough and start another walkabout MaPhattan project. Brooklyn beckons, but the ever-evolving NYC landscape is unpredictable, and it is hard to know where to move that won’t become overly gentrified or where you are not participating in such a predictable path.

On the work front, I published, in collaboration with many stellar scientists, 18 papers, the final one being the Food Systems Countdown Initiative paper and report. I started a new job as a Professor of Climate and Food at Columbia’s Climate School and as the Interim Director of the International Research Institute of Climate and Society. It has been an interesting adjustment since leaving Hopkins, with a lot of my team going on to spread their wings in other institutions. The Food Systems Dashboard is going strong along with other various projects.

On a personal note, we, the Sound Furies, finished our fifth album, Times Edit. My favorite song is Mandelbrot’s Coastline. I traveled a hell of a lot less and will continue on that path in 2024. What I will do in 2024 is spend some time curating and sharing all the photos I have taken on my 60+ country travels. 2023 was filled with ordinary experiences — I got COVID, which sucked. I walked an average of 5.8 miles per day, up from last year, which was 5.2 miles. I tried out the Peleton (there is one in my building) and found it ridiculous but effective. I ate red meat maybe five times and tried my best only to take public transport (maybe got in a taxi/uber 4-5 times) if walking wasn’t an option. I continue to bake sourdough…I decided I like folk music (maybe it’s my age) and succulents (maybe it’s my age). We celebrated our 27th wedding anniversary. I turned 52. We ate in 55 restaurants since arriving in NYC (hey, don’t give me shit, I’m in the food business).

Looking to 2024, the new year brings the opportunity to turn over a new leaf, improve, and make a change. But change is ruthlessly tough, and we are often hard on ourselves when we don’t make those changes “successfully.” And I must admit, I am worried about the changes to come. The poem, What they did yesterday afternoon, by Warsan Shire has been running through my head:

“later that night
i held an atlas in my lap
ran my fingers across the whole world
and whispered
where does it hurt?

it answered
everywhere
everywhere
everywhere.”

Almost half of the world will be voting for new leaders in 2024, and democracy looks pretty fragile to me. I worry about the U.S. elections, as I am sure almost every American does, and the results will impact future decisions about our lives and goals. I am also profoundly concerned about the lack of action on mitigating climate change, what that will mean for everyone, particularly the poorest and most vulnerable, how much they will need to adapt, and with what resources.

But as the late Sam Cooke beautifully sang, a change is gonna come – the question is, are we ready for whatever comes? Because things don’t always change for the better, but they do change. Rebecca Solnit, author of Hope in the Dark, wrote, "Incremental change can happen quietly, and change is rarely straightforward. Victories slip by unheralded while failures are more readily detected.” I will remain hopeful in 2024 as I run my fingers across the world. I am going to remain hopeful. Not because I think everything is going to be okay. But hope for the possibility that the change that is coming pushes us forward to a more sustainable future.
