Remembering Joan Gussow

News Feed
Wednesday, March 12, 2025

Joan Dye Gussow, who died last Friday at age 96, was a fiercely independent thinker and food-system visionary whose ideas caught on and rippled outward. Starting in the 1970s, through her groundbreaking nutritional ecology class at Teachers College within Columbia University, and through books like The Feeding Web: Issues in Nutritional Ecology, she transformed our view of food from something enjoyed at the end of a fork to the entire system that created the mouthful. Photo credit: Randy Harris, courtesy of Chelsea Green Publishing Gussow helped us understand that buying locally grown, seasonal food (and raising it ourselves, if possible) connected us to the health of the land, and to our own health, too. And because of her, we began to understand the deleterious impacts of the industrialized food system—among them depleted soil, poisoned water, and metabolic disease.  She railed at politicians for setting back progress and, as she told us in an interview, “You have to keep hope alive, you have to keep moving along the way you believe in and keep telling the truth and trying to get the word out there.” In person, Gussow was formidable and funny, speaking her brilliant mind with candor, urging us to see what was going on and to never stop asking hard questions. Luckily, many of us have heeded her call, and in our work and our lives, we continue the conversation she began.  We asked some of Gussow’s many fans to celebrate and remember her with us. For those who would like to share memories or photos through this link, created by her friend Pam Koch, please do so.  Dan Barber, chef and co-owner of Family Meal at Blue Hill in Manhattan and Blue Hill at Stone Barns To Joan, the professor: You changed the way we view a single strawberry and  taught us to trust cows more than chemists. For this and many other things, Joan, we salute you. To Joan, the writer: Political or personal, your prose was always beautiful and unflinching. For this and many other things, Joan, we salute you. To Joan, the nutritionist: You proved that it is not merely safe, but sensible (and not merely sensible, but imperative) to keep slathering butter on all those potatoes. For this and many other things, Joan, we salute you. To Joan, the activist: On health food zealots, always a baffling irritation for you, you delivered a consistent message: Ignore them. Your vitality was daily proof of that simple wisdom. For this and many other things, Joan, we salute you. To Joan, the botanist: We valued your pawpaws as much as your raspberries. Your green thumb lifted our blue moods. For this and many other things, Joan, we salute you. To Joan, the cook and critic: You cooked up what you dug. For agribusiness adversaries, you cooked up trouble. For this and many other things, Joan, we salute you. To Joan, the mother: You have raised all these issues and along the way you’ve raised us, too. Here’s hoping we will do you proud. For this and many other things, Joan, we salute you. And to Joan, the hedonist: Food was your medium, but your message was a philosophy of life. You taught us something more than nutrition and agriculture—you taught us how to eat, to indulge in pleasure by way of responsibility. Thank you. Ann Cooper, chef and founder of the Chef Ann Foundation  “Joan Gussow was truly an OG of the sustainable/ organic food movement, and an amazing thinker and educator.” Joan Gussow was truly an OG of the sustainable/organic food movement, and an amazing thinker and educator. She spoke at the 1996 Chefs Collaborative Retreat and told the group that some “food” should just not be organic. “An organic gummy bear or an organic Twinkie, organic Eggo Toaster Waffles . . . they just shouldn’t be organic.”  I was so inspired by her idea that we shouldn’t have organic junk food that it shaped many of my thoughts on sustainability. Joan was instrumental in some of my thinking for my book Bitter Harvest, and when I went to the Ross School to build a healthy, nutritious, delicious school food program, Joan graciously gave of her time and energy to teach and educate our team. I will be forever grateful for all she did for food systems and sustainability.  Leslie Hatfield with Joan Gussow. Photo courtesy of Hatfield. Leslie Hatfield, Senior Partnership and Outreach Advisor at GRACE Communications Foundation Joan was brilliant, no question, but what drew me to her was her fierce honesty. Whether writing about unchecked corporate power’s impacts on diets, or her marriage and subsequent widowhood, she asked hard questions and didn’t flinch in laying out the answers. She inspired me, on both personal and professional levels, to live a more honest and authentic life.  Elizabeth Henderson, farmer and co-chair, Interstate Council policy committee of the Northeast Organic Farming Association  I came to know Joan through my work as an organic farmer and as one of the first to organize a CSA [community supported agriculture system]. I was thrilled when she agreed to write the foreword to my 2000 book Sharing the Harvest. The first edition came out in 1998, when we estimated that there were about 1,000 CSAs in the U.S. By the second edition, in 2007, that number had more than doubled, and there may be as many as 7,000 today.  As a pioneering advocate of buying from local organic farms, Joan instantly grasped the significance of CSAs. In her foreword, Joan wrote: “Across this country, a movement is spreading that acknowledges a long-ignored reality: Most of what we pay for our food goes to companies that transport, process, and market what comes off the farms, not to farmers themselves. The people who actually grow food don’t get paid enough to keep on doing it. If we hope to keep on eating, however, we need to keep farmers in business; and if we want to keep farmers in business, it’s time for all of us, ordinary citizens and policy makers alike, to begin learning how that might be done. Sharing the Harvest is a great place to start.” Joan’s words are as urgent today as when she wrote them 28 years ago. Family-scale farms continue to go out of business, and the United States Department of Agriculture just cancelled the grant that would have enabled the CSA Innovation Network, a network of CSA networks all over the country, to support more diverse farms in creating CSAs. I will be eternally grateful to Joan for her encouragement to me as a farmer and as a writer, and for transforming the discipline of nutrition from the reductionist academic analysis of the food on our plates into a training program for active participants in the international movement to wrest power over food from corporate industrial domination and return it to the people who eat, and do the hard and joyous work of growing healthy, nutritious food. Photo credit: Susan Frieman, courtesy of Chelsea Green Publishing Pamela Koch, Mary Swarz Rose associate professor of nutrition and education, Teachers College, Columbia University Joan taught her transformative course, Nutritional Ecology, in the Program in Nutrition at Teachers College, Columbia University, from 1970 to 2021. I taught with her from 2012 to 2021. Each week students received a 50–60 page packet of readings on a topic such as the “true cost (i.e., the environmental, health, and social cost) of food.” Students wrote a one-page reflection paper on the readings, which could be written as a letter to a friend. My comments are a reflection letter to you, Joan.  Dear Joan, I miss your wit, your wisdom, and how we could reflect on an old reading, such as your 1980 piece “What corporations have done to our food,” and see something totally new in today’s context. You described our industrial food system as “insane” and “absurd.” You have taught me to always speak the truth and think critically.  Case in point: The fertilizers and pesticides used on farms have to pollute our rivers, oceans, and drinking water. How could they not? The ability to ask the tough questions is what we can all do to carry your torch. This gives me hope that we can heal our ecosystem, support public health, reduce food-related chronic diseases, and treat everyone who works all along the food chain fairly and justly. Because of you, Joan, I believe we will have a better food future. We need your hope, Joan, now, more than ever. Ellie Krieger, MS RDN, Food Network and PBS show host and James Beard award-winning cookbook author I remember the feeling of having my mind blown open by Joan Dye Gussow’s teaching. It was like suddenly seeing in three dimensions when I had only been seeing in two before. Understanding that nutrition is much more than just nutrients–that [it] is agriculture, politics, the environment, and more–shaped my thinking about food and the work I do to this day. Thank you, Joan, for your brilliance, bravery, persistence, and for leading by example. I consider myself a product of the big, robust garden you cultivated. Anna Lappé, author and executive director of the Global Alliance for the Future of Food Joan was a singular, uncompromising voice for organic and local food. I’ll always appreciate her generosity of spirit as a teacher, training countless students through her courses at Columbia Teachers College and opening her door to me personally as she took the time to help me understand food systems and the power of organic practices.  I’ll never forget interviewing her at her home in upstate New York for Grub: Ideas for an Urban Organic Kitchen. While we looked out at her overflowing vegetable garden that stretched to the waters of the Hudson River, Joan shared her food philosophy, including turning me onto her seminal essay about a hypothetical organic Twinkie.  While serving on the National Organic Standards Board, she had penned, “Can an Organic Twinkie Be Certified?” Her answer was yes. One day, a Twinkie could very well be certified organic if 95 percent of its ingredients were. But, she was quick to note, it would not be healthy—nor would it reflect her vision of a food system defined by local, healthy, whole foods and not highly processed ones.  I loved the last words of her New York Times obituary, which sounded every bit like the Joan I had been inspired by for years: “The day I die, I want to have a black thumb from where I hit it with a hammer and scratches on my hands from pruning the roses.” Kate MacKenzie, Executive Director of New York City’s Mayor’s Office of Food Policy  Joan Gussow has influenced my professional life more than any other. Twenty-five years ago, I started in the public health nutrition program at Teachers College, with a BS degree in Nutritional Sciences from Cornell. I often say that at Cornell, I learned everything about food after you swallow it, and everything about food before you eat it at TC, from Joan. “Perhaps now more than ever, we have the responsibility of carrying her legacy forward, to meaningfully connect to real food for the health of our people and our environment.” It was in her classes that I was introduced to topics like the corporate consolidation of the food system (or to even consider the words “food system”), the limits to population growth, how to feed the world, agricultural inputs like pesticides and organic practices, and the concepts of sustainability and local food.  I remember one class when she was lecturing about the number of food products on grocery store shelves, and how over time, people were made to think there was just no more time to cook. Her simple response: that we have always had 24 hours in the day, and it’s the power of marketing and industry to convince us otherwise. These issues made me deeply curious and desirous to effectuate changing the food system.   I’ve been doing that ever since graduating and I have met extraordinary leaders and visionaries throughout the U.S. and beyond. Many of those people have also been students of Joan’s. Perhaps now more than ever, we have the responsibility of carrying her legacy forward, to meaningfully connect to real food for the health of our people and our environment. Marion Nestle, Paulette Goddard professor of nutrition, food studies, and public health emerita, New York University I first met Joan in the late 1970s when I heard her give a talk in the Bay Area when I was teaching at the University of California San Francisco School of Medicine. I had never heard anyone talk about the need to link agricultural production to nutrition and health—food systems, we now call that—and it felt revelatory. I am not alone in being inspired by her work. I have followed it with great admiration. Ahead of her time? Absolutely. You have discovered that the food industry influences food choices? Try Joan’s “Who Pays the Piper,” from 1980. You think food systems should be sustainable? See Joan’s “Dietary Guidelines for Sustainability,” written with Kate Clancy in 1986. Her students at Columbia were so lucky to be in her orbit. I am beyond sad at her loss.  Raj Patel, ​​author, activist, and research professor in the Lyndon B. Johnson School of Public Affairs at the University of Texas, Austin Joan was so ahead of her time, I often wondered whether she thought the food movement revival a decade or two ago was just the history of the 1970s repeating, this time as farce. But she was always gracious, ready to celebrate the wins—and hurl imprecations at those who deserved them: the food industry, their shills, and the deer who ate from her garden. Recently, I re-read her classic lecture, “Women, Food, and the Survival of the Species,” plucked from the archives by Daniel Bowman Simon, and it reminded me of the abundance of her spirit, and the depth of our debt to her.  Michael Pollan, author, journalist Joan was one of my first and most influential teachers when it came to understanding food and agriculture as a system. (The other is Marion Nestle.) Joan saw the politics in all sorts of places people had trouble spotting it, such as the field of nutrition. We first met in the 1990s at the Culinary Institute of America, at a conference about genetically modified crops. She was formidable, and though I don’t recall what she said, it galvanized the room with its penetrating clarity.  She was a master at connecting the dots, and the fact that most of us understand food and agriculture as a single system, linking policy, soil, nutrition, public health, and technology, owes in large part to the work Joan did.  But she was much more than a theorist; indeed, she walked the talk, growing much of her own food on an oft-flooded piece of land right on the Hudson–a beautiful but perilous spot I had the privilege of visiting a couple of times.  The phrase, “Eat food, not too much, mostly plants,” owes at least two words to Joan. When I was researching In Defense of Food, I asked her to sum up what she had learned about how best to eat, and she didn’t miss a beat: “Eat food.” As in, real food, whole foods, unprocessed foods. I embroidered her message a bit, with “mostly plants” and “not too much” but the basic message—which is that we don’t and shouldn’t eat nutrients–was Joan’s. She was an inspiration. Tom Philpott, senior research associate at the Center for a Livable Future, Johns Hopkins University Joan Dye Gussow has passed on, but her legacy and influence will live as long as we have ecosystems and natural resources worth defending. Like all of our best and brightest food-system intellectuals, Joan understood that humanity doesn’t exist separately from nature or ecology, but lives deeply embedded within them. We are as much a part of nature as the lion skulking the savanna, or the warbler winging it from the Adirondacks to the Caribbean islands for winter; it’s just that we exert much more influence over the ecosystems we touch.  Joan elegantly summed up this concept in the title of her 1978 book, The Feeding Web: Issues In Nutritional Ecology. “Nutritional ecology”: The idea neatly connects our sustenance with the landscapes that feed us and provide sinks for our waste. Professionally, academically, she was a nutritionist, a field that evolved over decades in tight collaboration with corporate food giants, and too often reduced nutrition to a list of essential vitamins and minerals—commodities that, once injected into highly processed food, the idea went, make a health-giving diet.  “Perhaps what I will remember most about Joan is the laughter, the caring, and the closeness we shared, sometimes verging on tears.” Today, this ideology is finally unravelling under the weight of undeniable evidence. Joan rejected it more than a half century ago, and used her perch at Columbia University to launch broadsides against it. By the time I met her in the late 2000s, Joan was a doyenne of the anti-industrial food movement, renowned for her advocacy in support of local and regional food systems, and for her legendary garden on the banks of the Hudson, not far from New York City. It meant a lot to hear her say she had read and appreciated my journalism work, and it was delightful to be able to tell her how much I had learned from her. She was a happy and inspiring warrior against the forces of industrial agriculture.  And damn it, she was right. Her vision of robust local and regional food networks, bolstered by flourishing small- and mid-scale farms and justly compensated farm labor, represents a beacon for a livable future in an increasingly dystopian age. In a 2011 Civil Eats interview, she allowed that “compared to the reception my ideas got 30 years ago, it’s quite astonishing the reception they’re getting now,” citing the extraordinary artisanal food scenes emerging in places like Brooklyn. But, she added, “whether or not there’s going to be sea change in the whole system is so hard to judge.” Hard to judge, and harder still to achieve. It’s up to us, the generations she inspired, to make it so. I never managed to take her up on the invitation to visit her Hudson Valley garden. May it flourish in her memory forever. I still hope to see it someday. Joan Dye Gussow with Urvashi Rangan. Photo courtesy of Rangan. Urvashi Rangan, founding co-chair, Funders for Regenerative Agriculture (FORA) and chief science advisor, GRACE Communications Foundation  I had the immense pleasure of sharing in Joan’s professional and personal life. As a young scientist, I remember presenting to a nutrition conference and Joan was in the front row and asked many great questions. From then, I always knew to seek her professional opinion on the harms of industrial ag practices and the benefits of organic production. She then invited me to lecture in her classes and always wanted to know the latest goings-on in food politics.    Perhaps what I will remember most about Joan is the laughter, the caring, and the closeness we shared, sometimes verging on tears. I remember one conversation about gut microbiomes and people reseeding with poop from other people. We decided that Joan’s poop would be worth more than gold since her biome had only eaten organic food forever.   Despite the 40 years between us, I found Joan to be one of my closest and dear friends and one of the youngest people I have known. I remember leaving a conference in NYC together where she gave the keynote, and while we were driving home, she looked at me and said, “My God, Urvashi, there were some really old people there.” Joan wasn’t talking about age, but mindset (and she was so right).   And while she may have been the oldest person in the room, her mind and heart were youthful, yet wise. I used to tell her that when I grew up, I wanted to be just like her. She was a teacher until the end, in the classroom and out. I will miss her immensely and will cherish all of the times we had together.  Michael Sligh, founding chair, National Organic Standards Board Joan was that rare breed of academic, activist, and farmer. She helped us bridge movements and she was always on the right side of the fight. Tough as nails and a heart of gold. She will be missed. Kerry Trueman, sustainability advocate Joan was a dear friend and mentor to me, as she was to so many people. I became a die-hard devotee of her work after reading her first memoir, This Organic Life. We became friends several decades ago when she gave a talk at The New School. After she spoke, she mingled with the attendees, and I was so excited at the prospect of meeting her that I transcended my shyness to tell her how she had inspired me to plant pawpaws in my yard. Joan, in her inimitable acerbic-yet-affectionate way, liked to say that I had “stalked” her. She once called me her “favorite beneficial pest,” which, coming from her, was a thrilling compliment. What an honor it was to collaborate with her, to be a guest at so many memorable meals in her lovely home, to work side by side with her to restore her legendary garden after the Hudson River flooded it. The second time the river rose up to swallow her garden, she rose even higher, literally, by raising the soil level to accommodate the consequences of climate change. Her refusal to throw in the trowel in the wake of such destruction was quintessential Joan.  Her perseverance was just one of Joan’s many admirable traits, another being that she was not a purist. For her, eating locally meant being a regular at her local diner, regardless of how they sourced their eggs and bacon. How grateful I am to have known her. Karen Washington with Joan Gassow. Photo courtesy of Washington. Karen Washington, farmer, activist, and co-founder of Black Urban Growers Joan was such a kind and loving person. Her first act of kindness was to invite me and my gardeners from the Bronx to come visit and have lunch. Many of them did not speak English, but were able to enjoy her company, her garden, and the food. She loved people and was willing to share her home with strangers.  We became close as board members of Just Food. Her knowledge and wisdom of the food system was incredible. She taught me to be courageous and not sit by and allow things to happen, but to challenge things that were hard. I loved her so much and will miss her, but I will carry a piece of her in my work to fight against injustice. Alice Waters, chef, author, food activist, founder of Chez Panisse and The Edible Schoolyard Joan had a HUGE influence on my life and my thinking. “Eat locally, think globally” became my motto for Chez Panisse, and now for school food purchasing everywhere.

Joan was so ahead of her time, I often wondered whether she thought the food movement revival a decade or two ago was just the history of the 1970s repeating, this time as farce. But she was always gracious, ready to celebrate the wins—and hurl imprecations at those who deserved them: the food industry, their shills, and the deer who ate from her garden. Recently, I re-read her classic lecture, “Women, Food, and the Survival of the Species,” plucked from the archives by Daniel Bowman Simon, and it reminded me of the abundance of her spirit, and the depth of our debt to her. 

Michael Pollan, author, journalist

Joan was one of my first and most influential teachers when it came to understanding food and agriculture as a system. (The other is Marion Nestle.) Joan saw the politics in all sorts of places people had trouble spotting it, such as the field of nutrition. We first met in the 1990s at the Culinary Institute of America, at a conference about genetically modified crops. She was formidable, and though I don’t recall what she said, it galvanized the room with its penetrating clarity. 

She was a master at connecting the dots, and the fact that most of us understand food and agriculture as a single system, linking policy, soil, nutrition, public health, and technology, owes in large part to the work Joan did. 

But she was much more than a theorist; indeed, she walked the talk, growing much of her own food on an oft-flooded piece of land right on the Hudson–a beautiful but perilous spot I had the privilege of visiting a couple of times. 

The phrase, “Eat food, not too much, mostly plants,” owes at least two words to Joan. When I was researching In Defense of Food, I asked her to sum up what she had learned about how best to eat, and she didn’t miss a beat: “Eat food.” As in, real food, whole foods, unprocessed foods. I embroidered her message a bit, with “mostly plants” and “not too much” but the basic message—which is that we don’t and shouldn’t eat nutrients–was Joan’s. She was an inspiration.

Joan Dye Gussow has passed on, but her legacy and influence will live as long as we have ecosystems and natural resources worth defending. Like all of our best and brightest food-system intellectuals, Joan understood that humanity doesn’t exist separately from nature or ecology, but lives deeply embedded within them. We are as much a part of nature as the lion skulking the savanna, or the warbler winging it from the Adirondacks to the Caribbean islands for winter; it’s just that we exert much more influence over the ecosystems we touch. 

Joan elegantly summed up this concept in the title of her 1978 book, The Feeding Web: Issues In Nutritional Ecology. “Nutritional ecology”: The idea neatly connects our sustenance with the landscapes that feed us and provide sinks for our waste. Professionally, academically, she was a nutritionist, a field that evolved over decades in tight collaboration with corporate food giants, and too often reduced nutrition to a list of essential vitamins and minerals—commodities that, once injected into highly processed food, the idea went, make a health-giving diet. 

“Perhaps what I will remember most about Joan is the laughter, the caring, and the closeness we shared, sometimes verging on tears.”

Today, this ideology is finally unravelling under the weight of undeniable evidence. Joan rejected it more than a half century ago, and used her perch at Columbia University to launch broadsides against it.

By the time I met her in the late 2000s, Joan was a doyenne of the anti-industrial food movement, renowned for her advocacy in support of local and regional food systems, and for her legendary garden on the banks of the Hudson, not far from New York City. It meant a lot to hear her say she had read and appreciated my journalism work, and it was delightful to be able to tell her how much I had learned from her. She was a happy and inspiring warrior against the forces of industrial agriculture. 

And damn it, she was right. Her vision of robust local and regional food networks, bolstered by flourishing small- and mid-scale farms and justly compensated farm labor, represents a beacon for a livable future in an increasingly dystopian age. In a 2011 Civil Eats interview, she allowed that “compared to the reception my ideas got 30 years ago, it’s quite astonishing the reception they’re getting now,” citing the extraordinary artisanal food scenes emerging in places like Brooklyn. But, she added, “whether or not there’s going to be sea change in the whole system is so hard to judge.”

Hard to judge, and harder still to achieve. It’s up to us, the generations she inspired, to make it so. I never managed to take her up on the invitation to visit her Hudson Valley garden. May it flourish in her memory forever. I still hope to see it someday.

I had the immense pleasure of sharing in Joan’s professional and personal life. As a young scientist, I remember presenting to a nutrition conference and Joan was in the front row and asked many great questions. From then, I always knew to seek her professional opinion on the harms of industrial ag practices and the benefits of organic production. She then invited me to lecture in her classes and always wanted to know the latest goings-on in food politics.   

Perhaps what I will remember most about Joan is the laughter, the caring, and the closeness we shared, sometimes verging on tears. I remember one conversation about gut microbiomes and people reseeding with poop from other people. We decided that Joan’s poop would be worth more than gold since her biome had only eaten organic food forever.  

Despite the 40 years between us, I found Joan to be one of my closest and dear friends and one of the youngest people I have known. I remember leaving a conference in NYC together where she gave the keynote, and while we were driving home, she looked at me and said, “My God, Urvashi, there were some really old people there.” Joan wasn’t talking about age, but mindset (and she was so right).  

And while she may have been the oldest person in the room, her mind and heart were youthful, yet wise. I used to tell her that when I grew up, I wanted to be just like her. She was a teacher until the end, in the classroom and out. I will miss her immensely and will cherish all of the times we had together.

Joan was that rare breed of academic, activist, and farmer. She helped us bridge movements and she was always on the right side of the fight. Tough as nails and a heart of gold. She will be missed.

Kerry Trueman, sustainability advocate

Joan was a dear friend and mentor to me, as she was to so many people. I became a die-hard devotee of her work after reading her first memoir, This Organic Life. We became friends several decades ago when she gave a talk at The New School. After she spoke, she mingled with the attendees, and I was so excited at the prospect of meeting her that I transcended my shyness to tell her how she had inspired me to plant pawpaws in my yard. Joan, in her inimitable acerbic-yet-affectionate way, liked to say that I had “stalked” her. She once called me her “favorite beneficial pest,” which, coming from her, was a thrilling compliment.

What an honor it was to collaborate with her, to be a guest at so many memorable meals in her lovely home, to work side by side with her to restore her legendary garden after the Hudson River flooded it. The second time the river rose up to swallow her garden, she rose even higher, literally, by raising the soil level to accommodate the consequences of climate change. Her refusal to throw in the trowel in the wake of such destruction was quintessential Joan. 

Her perseverance was just one of Joan’s many admirable traits, another being that she was not a purist. For her, eating locally meant being a regular at her local diner, regardless of how they sourced their eggs and bacon. How grateful I am to have known her.

Joan was such a kind and loving person. Her first act of kindness was to invite me and my gardeners from the Bronx to come visit and have lunch. Many of them did not speak English, but were able to enjoy her company, her garden, and the food. She loved people and was willing to share her home with strangers. 

We became close as board members of Just Food. Her knowledge and wisdom of the food system was incredible. She taught me to be courageous and not sit by and allow things to happen, but to challenge things that were hard. I loved her so much and will miss her, but I will carry a piece of her in my work to fight against injustice.

Joan had a HUGE influence on my life and my thinking. “Eat locally, think globally” became my motto for Chez Panisse, and now for school food purchasing everywhere.

Amid state inaction, California chef sues to block sales of foam food containers

The suit claims Atlanta-based WinCup continues to sell, distribute and market foam products in California despite a state law that was supposed to ban such sales starting Jan. 1.

Redwood City — Fed up with the state’s refusal to enforce a law banning the sale of polystyrene foam cups, plates and bowls, a San Diego County resident has taken matters into his own hands.Jeffrey Heavey, a chef and owner of Convivial Catering, a San Diego-area catering service, is suing WinCup, an Atlanta-based foam foodware product manufacturing company, claiming that it continues to sell, distribute and market foam products in California despite a state law that was supposed to ban such sales starting Jan. 1. He is suing on behalf of himself, not his business.The suit, filed in the San Diego County Superior Court in March, seeks class action status on behalf of all Californians. Heavey’s attorney, William Sullivan of the Sullivan & Yaeckel Law Group, said his client is seeking an injunction to stop WinCup from selling these banned products in California and to remove the products’ “chasing arrows” recycling label, which Heavey and his attorney describe as false and deceptive advertising.They are also seeking damages for every California-based customer who paid the company for these products in the last three years, and $5,000 to every senior citizen or “disabled” person who may have purchased the products during this time period.WinCup didn’t respond to requests for comments, but in a court filing described the allegations as vague, unspecific and without merit, according to the company’s attorney, Nathan Dooley. Jeffrey Heavey is suing foodware maker WinCup, claiming that it continues to sell, distribute and market foam products in California despite a state law that was supposed to ban such sales starting Jan. 1. (Luke Johnson / Los Angeles Times) At issue is a California ban on the environmentally destructive plastic material, which went into effect on Jan. 1, as well as the definition of “recyclable” and the use of such a label on products sold in the state.Senate Bill 54, signed into law by Gov. Gavin Newsom in 2021, targeted single-use plastic in the state’s waste stream. The law included a provision that banned the sale and distribution of expanded polystyrene food service ware — such as foam cups, plates and takeout containers — on Jan. 1, unless producers could show they had achieved a 25% recycling rate.“I’m glad a person in my district has taken this up and is holding these companies accountable,” said Catherine Blakespear (D-Encinitas). “But CalRecycle is the enforcement authority for this legislation, and they should be the ones doing this.”The intent of the law was to put the financial onus of responsible waste management onto the producers of these products, and away from California’s taxpayers and cities that would otherwise have to dispose of these products or deal with their waste on beaches, in rivers and on roadways.Expanded polystyrene is a particularly pernicious form of plastic pollution that does not biodegrade, has a tendency to break down into microplastics, leaches toxic chemicals and persists in the environment.There are no expanded polystyrene recycling plants in California, and recycling rates nationally for the material hover around 1%.

(Wolfgang Kaehler / LightRocket via Getty Images) However, despite CalRecycle’s delayed announcement of the ban, companies such as WinCup not only continue to sell these banned products in California, but Heavey and his lawyers allege the products are deceptively labeled as “recyclable.” In his suit, Heavey includes a March 15 receipt from a Smart & Final store in the San Diego County town of National City, indicating a purchase of “WinCup 16 oz. Foam” cups. Similar polystyrene foam products could be seen on the shelves this week at a Redwood City Smart & Final, including a 1,000-count box of 12-ounce WinCup foam cups selling for $36.99. Across the aisle, the shelves were packed with bags of Simply Value and First Street (both Smart & Final brands) foam plates and bowls.There were “chasing arrow” recycling labels on the boxes containing cup lids. The symbol included a No. 6 in the center, indicating the material is polystyrene. There were none on the cardboard boxes containing cups, and it couldn’t be determined if the individual foam products were tagged with recycling labels. They were either obstructed from view inside cardboard boxes or stacked in bags which obscured observation.Smart & Final, which is owned by Chedraui USA, a subsidiary of Mexico City-based Grupo Comercial Chedraui, didn’t respond to requests for comment.Heavey’s suit alleges the plastic product manufacturer is “greenwashing” its products by labeling them as recyclable and in so doing, trying to skirt the law.According to the suit, recycling claims are widely disseminated on products and via other written publications. The company’s website includes an “Environmental” tab, which includes a page entitled: “Foam versus Paper Disposable Cups: A closer look.”The page includes a one-sentence argument highlighting the environmental superiority of foam over paper, noting that “foam products have a reputation for environmental harm, but if we examine the scientific research, in many ways Expanded Polystyrene (EPS) foam is greener than paper.”Heavey’s suit claims that he believed he was purchasing recyclable materials based on the products’ labeling, and he would not have bought the items had they not been advertised as such. WinCup, which is owned by Atar Capital, a Los Angeles-based global private investment firm sought to have the case moved to the U.S. District Court in San Diego, but a judge there remanded the case back to the San Diego Superior Court or jurisdiction grounds. Susan Keefe, the Southern California Director of Beyond Plastics, an anti-plastic environmental group based in Bennington, Vt., said that as of June, the agency had not yet enforced the ban, despite news stories and evidence that the product was still being sold in the state.“It’s really frustrating. CalRecycle’s disregard for enforcement just permits a lack of respect for our laws. It results in these violators who think they can freely pollute in our state with no trepidation that California will exercise its right to penalize them,” she said. Melanie Turner, a spokesoman for CalRecycle, said in a statement that expanded polystyrene producers “should no longer be selling or distributing expanded polystyrene food service ware to California businesses.” “CalRecycle has been identifying and notifying businesses that may be impacted by SB 54, including expanded polystyrene requirements, and communicating their responsibilities with mailed notices, emailed announcements, public meetings, and workshops,” she said. The waste agency “is prioritizing compliance assistance for producers regulated by this law, prior to potential enforcement action,” she said.Keefe filed a public records request with the agency regarding communications with companies selling the banned material and said she found the agency had not made any attempts to warn or stop the violators from selling banned products.Blakespear said it’s concerning the law has been in effect for more than six months and CalRecycle has yet to clamp down on violators. Enforcement is critical, she said, for setting the tone as SB 54 is implemented.According to Senate Bill 54, companies that produce banned products that are then sold in California can be fined up to $50,000 per day, per violation.According to a report issued by the waste agency last week, approximately 47,000 tons of expanded polystyrene foam was disposed in California landfills last year.

Microwaves produce radiation. Is that bad for me?

A Vox reader asks: Are microwaves actually bad for you, your health, and the food you eat? I think anybody who’s ever “nuked” some leftovers or a ready-made meal has pondered the same question. Nuke? As in the same nuclear radiation that causes deformities and mutations in my favorite science fiction? What exactly am I […]

Your microwave is not going to kill you. | Santiago Barrio/Cover/Getty Images A Vox reader asks: Are microwaves actually bad for you, your health, and the food you eat? I think anybody who’s ever “nuked” some leftovers or a ready-made meal has pondered the same question. Nuke? As in the same nuclear radiation that causes deformities and mutations in my favorite science fiction? What exactly am I doing to my body? It’s an understandable concern. It seems like so much of what we eat is bad for us, and US Health and Human Services Secretary Robert F. Kennedy Jr. constantly warns Americans that modern conveniences could be allowing invisible particles into our bodies that damage our health. It made sense then, that some staffers on his presidential campaign were reportedly fearful of radiation from kitchen microwaves. But here is the good news: You are not ingesting toxic nuclear radiation. Microwaves are in fact quite safe — but there are a few precautions you should be aware of, if only to avoid that tinge of anxiety the next time you hit start on your instant oatmeal. Let’s start here: Microwaves produce a very different kind of radiation than a nuclear reaction. A nuclear bomb’s detonation will emit ionizing radiation. That stuff carries so much energy it can actually strip electrons out of individual atoms, which can damage your body at the cellular level and potentially lead to cancer and other illnesses. A microwave will not. The radiation produced by your kitchen microwave, on the other hand, is “non-ionizing.” These are electromagnetic waves that are similar to radio and light waves. Non-ionizing radiation is much, much less powerful than the other kind, which means it does not possess the necessary energy to alter your DNA at the molecular level.  While prolonged, direct and intense exposure could lead to tissue damage, we are exposed to non-ionizing electromagnetic radiation all the time with no significant health harms, according to the Centers for Disease Control and Prevention. Visible light — literally the light waves from the sun or a light bulb that our eyes pick up and our brains turn to images — is even a low-grade form of it. Plus, microwaves are appliances that the FDA strictly regulates to reduce any potential risk of radiation leakage; the agency says radiation injury from microwaves is “very rare” and associated with extremely unusual circumstances or the microwave being in poor condition. Okay, we’re not radiating ourselves when we nuke a slice of pizza. That’s good. But you may still be wondering: Am I ruining the food somehow? While I personally hate the way a piece of pizza tastes after being microwaved, when considering the nutritional value (of pizza or anything else), heating your food in the microwave isn’t going to hurt it. “The non-ionizing radiation used by a microwave does not make the food radioactive,” according to the US Environmental Protection Agency. And it won’t deplete your food of its nutritional value either:  As Harvard Medical School’s Anthony Komaroff wrote in 2019, “microwave cooking is actually one of the least likely forms of cooking to damage nutrients.” The reason is simple: time. We invented microwaves to have a quicker way to heat up food and, as it turns out, that also confers some nutritional benefits. Foods leach nutrients when they are under more heat for a longer period of time. By shortening the amount of time that your food is being heated, microwaves allow it to retain more of its vitamins and minerals. It’s unambiguously better than boiling, for example, during which the hot water removes many of the nutrients. How microwaving compares to roasting, sauteeing, or air-frying depends on the vegetable, but in general, microwaves are no worse for your food — from a nutritional point of view — than other forms of cooking. Alright, microwaves aren’t slowly poisoning you, nor are they robbing your food of its health benefits. Are there any catches? Sort of.  There are at least two precautions to take when using your microwave. First, make sure you are using a safe container. Never, ever put metal in the microwave. And don’t put plastic bowls or containers in there either: Everybody is freaking out about microplastics, BPAs, and PFAS these days — and for good reason: When it comes to microwaves, you do have some reason to worry. Studies have indicated that chemicals can leach into your food if you heat your food in them using a microwave. Once they enter your body, microplastics could damage your heart and other organs, disrupt your digestion, and affect your mental sharpness. You may be better off with glass or ceramic containers. At the very least, check that the plates or bowls you’re using in a microwave have been labeled safe for that use. You may want to consider replacing containers after a lot of microwave use because the risk of leaching harmful chemicals increases with time or if they have been damaged in some way. And then there is one other kind of harm from microwaves that health officials worry about: burns. Anybody who has grabbed a plate out of their microwave as soon as the buzzer sounds knows they can produce intense heat that can burn your body when you grab your food or your tongue and mouth when you ingest it. That is what the FDA is warning consumers to be mindful of, rather than nuclear mutations. The fear of turning into an extra from the Mad Max post-apocalypse should not dissuade you from using your kitchen’s microwave — so long as you are also using an appropriate container and you handle it with care. Instead, focus on what preparation will be the most satisfying to you, and some people may want to consider what will provide the most nutritional value.  Me? I can’t stand microwaved pizza anyway. It’s always going in the oven: 325 degrees, for 10 minutes.

Nanoplastics Make Up Most of the Ocean’s Plastic Pollution

Nanoplastics—particles smaller than a human hair—can pass through cell walls and enter the food web. New research suggest 27 million metric tons of nanoplastics are spread across just the top layer of the North Atlantic

Most Plastic in the Ocean Is Invisible—And DeadlyNanoplastics—particles smaller than a human hair—can pass through cell walls and enter the food web. New research suggest 27 million metric tons of nanoplastics are spread across just the top layer of the North AtlanticBy Katharine Sanderson & Nature magazine Sergi Escribano/Getty ImagesMarine plastic litter tends to grab headlines, with images of suffocating seabirds or bottles washing up along coastlines. Increasingly, researchers have been finding tiny microplastic fragments across all environments, from the most densely populated cities to pristine mountaintops, as well as in human tissue including the brain and placenta. A study published today reveals yet another hidden source of this deadly waste: nanometre-scale particles are literally everywhere, says co-author Dušan Materić, an environmental analytical chemist at the Helmholtz Centre for Environmental Research in Leipzig, Germany.Materić and his colleagues sampled water at three depths representative of different environments in the North Atlantic Ocean. Throughout the water column, they found three types of nanoplastic: polyethylene terephthalate (PET), polystyrene (PS) and polyvinylchloride (PVC). These were present at average concentrations of 18 milligrams per metre cubed, which translates to 27 million tonnes of nanoplastics spread across just the top layer of the temperate to subtropical North Atlantic. “Nanoplastics make up the dominant fraction of marine plastic pollution,” Materić says. In the entire world’s oceans, it is estimated that there are around 3 million tonnes of floating plastic pollution — excluding nanoplastics.What are plastic nanoparticles and how different are they from microplastics?On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.The tiniest of pieces of plastic, nanoplastics are defined by the researchers as having a diameter of less than one micrometre (one one-thousandth of a metre). Microplastics are between one micrometre and 5 millimetres across. At the smaller scale of nanoplastics, materials behave differently. Materić and his colleagues found that the particles were distributed throughout the water column, rather than settling to the bottom. The movement of the nanoplastic particles was dominated not by gravity, but by the random movement called Brownian motion, and by collisions with water molecules.How did the team find the nanoplastics?The scientists took water samples during a November 2020 cruise on research vessel Pelagia, which is owned by the Royal Netherlands Institute of Sea Research in Texel. They sampled at 12 locations: 5 in the system of circular currents called the North Atlantic subtropical gyre; 4 in the open ocean; and 3 from coastal areas on the European continental shelf. At each location, they gathered samples at depths of 10 metres and 1,000 metres below the surface, and then 30 metres off the ocean bottom.The nanoplastics were detected using a technology called thermal-desorption proton-transfer-reaction mass spectrometry. “We faced multiple challenges,” says Materić, including the need to remove contaminants other than nanoplastics. Each 10-millilitre sample was run through a filter with micrometre pores to clear out microplastics. Samples were then slowly heated, releasing any organic matter and allowing the remaining plastics to be identified.Not all was as expected. “We faced a big mystery,” says Materić. One major class of plastics, polyethylene (PE), was missing from the data, even though fragments almost certainly enter the ocean. The fragments probably transform into something else, or might fall to the sea bed, says Materić. “This suggests that PE nanoplastic cycling in the ocean environment follows some unusual pathway — either rapid chemical alteration or mineralization, or fast sinking.”Should we be surprised that nanoplastics are an overlooked source of plastics pollution? Should we be worried?“This does not come as a surprise to me, as I have been aware of the extent and magnitude of the problem for some time,” says Tony Walker, an environmental scientist at Dalhousie University in Halifax, Canada. “Nanoplastics, unlike microplastics, are able to pass through cell walls, meaning that they are already incorporated into the ocean phytoplankton which serve as the base of the marine food web and are able to be transferred through the marine food web,” he explains.The ubiquitousness of nanoplastics means they should be taken seriously, says Materić. “Given their toxicological potential, they may represent the most problematic plastic size fraction for ocean life,” he says. Walker agrees: “This should be a wake-up call to all of us,” he says. “The extent to which nanoplastics can infiltrate every ecosystem and living cell on the planet is even far worse than what we already know about microplastics and larger plastic pollution.”What can be done to mitigate the pollution?The next and likely final round of negotiations for a legally binding United Nations treaty on plastics pollution will kick off in August in Geneva, Switzerland. On the table is a limit on future plastic manufacture, but this is being resisted by some countries, including those that rely on oil and gas exports to power their economies.“One of the best strategies to mitigate future nanoplastics pollution or release into the environment is to cap plastic production,” says Walker. “Turn off the tap.”This article is reproduced with permission and was first published on July 9, 2025.

Dear Doctor: Sun exposure is the primary cause of thinning skin

"Could I take vitamin K or increase my platelets to limit this happening?"

DEAR DR. ROACH: I thought you could help with a stubborn problem. I am a healthy and active 78-year-old woman who, I admit, likes to look younger than my age. The problem is my skin, especially on my hands and arms; I get these bruises that look unsightly and take a while to resolve. I hear it is from age-related thin skin. My friends of this generation also complain about these red spots or bruises. They don’t hurt.Could I take vitamin K or increase my platelets so as to limit their happening? I’ve read not to take aspirin or any pain reliever. Is there any medicine to take to help my blood coagulate better or make my skin thicker? -- S.M.ANSWER: This common problem is called solar purpura, and it is largely the sun causing the damage to the skin, thinning it with age. Avoiding the sun and moisturizing your skin diligently can reduce the risk of this happening. Once it’s happened, these measures are still important for preventing it from getting worse.You should still avoid the sun and moisturize to prevent the condition from worsening. One study showed that bioflavinoid supplements helped reduce new bruises. These aren’t particularly expensive, but you can also get them through food, specifically citrus and other fruits.Vitamin K deficiency causes clotting problems, but taking more vitamin K doesn’t help. Aspirin does reduce the effectiveness of platelets, but if you are prescribed it (for blockages in the heart, for example), you should definitely keep taking it. Occasional ibuprofen has little effect on platelets, and acetaminophen (Tylenol) has none.DEAR DR. ROACH: For years, I have been plagued by a chronic nasal drip. It’s usually most present in the mornings, though it seems to be intermittent during the day. I frequently have to wipe or blow my nose. I thought it might be due to allergies, so I have been taking a Zyrtec tablet every morning. But it doesn’t seem to have any effect.I talked with my primary care physician about this, but he didn’t have any recommendations. I don’t know what is going on or how to stop this. Do you have any recommendations? -- R.M.ANSWER: An antihistamine like Zyrtec is a reasonable thing to try as allergic rhinitis often responds to antihistamines. (We just love our Latin and Greek names, and “rhinitis” comes from the Greek roots for “inflammation of the nose.”) Since an antihistamine didn’t work, it seems likely that you might have nonallergic rhinitis, and a nasal spray like ipratropium is usually effective for this.I also recommend azelastine nasal spray, which is now available over the counter as “Astepro.” There are some steps you can do to help your environmental risk, such as reducing dust and avoiding excess dryness.I warn people against the habitual use of nasal decongestants like Afrin, which should only be used for a day or two -- never more than three. Once the body gets used to it, nasal congestion will worsen every time a person tries to go without it.If the nasal spray doesn’t do the job, I’d recommend an evaluation by an expert, such as an otorhinolaryngologist, who may need to look for nasal polyps, laryngopharyngeal reflux, and other less-common causes.Dr. Roach regrets that he is unable to answer individual letters, but will incorporate them in the column whenever possible.

Ashland Earth Day celebrants find ways to help the planet, say ‘hang in there’

Ashland is a year-round Earth Day with "people who are creating organic, local, sustainable food, drink and music," said A Street Block Party participant Emily Simon.

Joe Bianculli participated in the first Earth Day on April 22, 1970, and 55 years later, he was handing out environmental-action information to throngs of people attending Ashland’s first Earth Day A Street Block Party. Biancelli, who lives in Ashland and volunteers for Klamath-Siskiyou Wildlands (“KS Wild”), said on Tuesday, “We had high hopes for saving the planet and we still have high hopes. It’s getting tougher and tougher every year, but we all have to hang in there.”The ecologically focused event in the historic Railroad District stretched for blocks along A Street, past the Ashland Food Co-op and Masala Bistro to the KS Wild open house, where Biancelli handed out stickers that read “Love where you live, defend what you love” in the front yard as the bluegrass band Eight Dollar Mountain performed in the backyard.About 1,000 people attended the free outdoor event organized by Karolina Lavagnino of Wild Thyme Productions.People chatted in line to order from the Tacos Libertad food truck in the parking lot used year round by customers of Get ‘N Gear second-hand outdoor equipment and clothing stores. Near an outdoor display of used kayaks and bikes for sale, volunteers of Ashland Devo explained the group’s mission: to cultivate grit, resilience and camaraderie in youth through the sport of mountain biking. Board member Moneeka Settles said Earth Day is simple: It’s a chance to “gather together and celebrate Earth.”Across A Street, in a lot next to the Ashland Yoga Center, Suzee Grilley was leading Elbow Room Taiko drummers, who captivated a large crowd with their rhythmic sound and dramatic movements around barrel-shaped drums.“We always celebrate Earth Day,” said Grilley. “We feel a lot of our music expresses a communing with nature, and the sprits that animate nature, from the trees, to the sky, to the water, to the earth itself, to human beings and animals.”She said the drums the group play reflect nature. “Every one of our drums is made of wood, skin and metal, and crafted with love and prayer by an artisan,” she said.Vince DiFrancesco of the Siskiyou Mountain Club, which works to maintain more than 400 miles of backcountry trails, welcomed people to his booth set up between the Grange Co-op and Ace Hardware.DiFrancesco sees Earth Day as a time for public service. “It’s about getting out and doing work on public lands to keep them open for recreation for everybody,” he said. Nearby, musician Gatore Mukarhinda drummed a heartbeat and sang a love song to Mother Earth. “She says, ‘take care of me,’” he said.Aubrey Laughlin of Talent, who had recently volunteered for Siskiyou Mountain Club trail work, said the idea for Earth Day was about “looking out for the next generation and connecting with each other, the place we live and our community.” Marie DeGregorio of Medford, who also attended the street party, said the day reminds people that “the planet needs help and we are stewards.”Party goer Susan Cox of Ashland agreed. To her, the day means “taking care of the planet, and each one of us doing our part as best we can and keeping it happy.” Yu Kuwabara of Ashland, who rode his bike to the event, said “Earth Day is a celebration of getting outside and enjoying the community.” Plenty of people rolled into the event on bikes, and Piccadilly Cycles provided free bike valet parking in front of its store.People gathered around booths displaying handmade jewelry and vendors selling treats like vegan- and gluten-free Plant Baked cookies, donuts, blueberry limoncello squares and cinnamon swirl loaves.Bloomsbury Books, a landmark independent bookstore on Ashland’s East Main Street, had a pop-up shop with nature-focused books. Earth Day is a day to learn about the environment, said bookstore co-owner Megan Isser. “Come read,” she said, gesturing to a table with copies of books, including “Garden Guide for the Rogue Valley,” published by the Jackson County Master Gardener Association with support from the Oregon State University Extension Service. Adults tasted small-batch wines from Circadian Cellars at the Ashland Recycled Furniture store, and mocktails by Hummingbird Heart Co. in a lot near Fourth Street.Creekside Strings fiddlers kicked off the event around 4 p.m. with traditional tunes in front of La Baguette Music Cafe, well known for its weekly jazz sessions. The event ended there too at 7:30 p.m. after a performance by folk duo Jenika Smith and Simon Chrisman.To block party participant Emily Simon, the best place to be on Earth Day was in Ashland, where she lives and supports sustainable businesses year round. “It’s such a wonderful event to be out here with our neighbors,” she said, “and celebrating the Earth with people who are creating organic, local, sustainable food, drink and music.”Upcoming Earth Day events:ScienceWorks Hands-on Museum hosts its annual Earth Day celebration 3:30-7 p.m. Friday, April 25, with activities highlighting the science of sustainability at 1500 E.
