In Hawai‘i, Restoring Kava Helps Sustain Native Food Culture

News Feed
Monday, February 24, 2025

Last fall, Ava Taesali opened Kava Queen, O‘ahu’s only brick-and-mortar kava bar, after three years of building a loyal following for this traditional beverage at farmers’ markets in Honolulu. Located in the repurposed Waialua Sugar Mill, former home of a sugar industry giant, the establishment is surrounded by a mix of local businesses that includes a yoga studio, a surf shop, and a sewing collective. The eclectic space reflects the North Shore’s laid-back, community vibe—a perfect backdrop for sipping the Polynesian brew. “Kava is meant to bring people together,” said Taesali. Earthy, bitter, and tingly on the tongue, kava—‘awa in Hawaiian—calms the body without dulling the brain. “The only thing it numbs is your mouth,” said Taesali, a Samoan American whose first name, aptly, means kava in Samoan. Kava, also known as Piper methysticum, is a perennial shrub with large, heart-shaped leaves. Its fibrous root, when crushed and steeped in water and massaged to release its essence, produces a cloudy, cool infusion traditionally served in an apu, or coconut-shell cup. Consumed in the South Pacific for at least 2,000 years for pleasure, relaxation, and in cultural and spiritual ceremonies, the drink holds deep significance in both Hawaiian mythology and Polynesian identity. “This designation helps sustain Native culture, reassure public health, and encourage state food sovereignty.” Beyond its traditional ceremonial and social importance, kava’s calming effects have sparked new research into kavalactones, the plant’s active compounds known to reduce stress, as an anti-anxiety remedy. Studies have also found that the elixir may have broader medicinal potential, from anti-cancer benefits to treatment for post-traumatic stress disorder. Despite these findings, the U.S. Food and Drug Administration (FDA) has yet to embrace these benefits. A longstanding federal advisory memorandum labels kava as an “unsafe” ingredient and classifies it as “an unapproved food additive,” citing unresolved health concerns including potential liver damage and cancer. The FDA’s Generally Recognized as Safe (GRAS) designation deems substances safe to use in foods and beverages, covering everything from staples such as salt and vinegar to certain food dyes and other controversial additives. However, the FDA has withheld GRAS status from kava, classifying it instead as a dietary supplement alongside vitamins, herbs, and probiotics, subjecting it to stricter labeling requirements and health warnings—as well as lower consumer demand. Beyond limiting kava’s mainstream acceptance, the cautious stance has also cast a shadow over its reputation, overshadowing its deep-rooted significance in Polynesian culture. Last year, however, Hawai‘i took matters into its own hands by labeling the root as GRAS. While states can’t overturn federal standards, they can set their own restrictions—California, for example, bans potassium bromate, a baking additive—or, as is the case here, make exceptions for certain substances.

It also aligns with the international Codex Alimentarius, the food safety standard of the World Health Organization (WHO), which recognized the safety of traditional kava preparations in 2020, citing their cultural significance to Native Polynesians. “This designation helps sustain Native culture, reassure public health, and encourage state food sovereignty,” said Kristen Wong, an information specialist for the Hawai‘i Department of Health (DOH). The Stigma Surrounding Kava Advocates blame the kava controversy on widespread adulteration of the ingredient. In 2002, Germany banned the substance due to reports of liver toxicity, which were later traced to extracts mixed with kratom, a Southeast Asian herb linked to liver damage and addiction. Though the national ban was eventually lifted, the stigma lingers. “There are so many misconceptions about kava,” Taesali said, adding that official recognition is key to changing the narrative. Kava has endured a long history of adversity, said Lakea Trask, a Hawaiian farmer and local activist who cultivates kava and other Native crops for Kanaka Kava, his family’s farm-to-table restaurant in Kailua-Kona, on the Big Island. The plant has weathered centuries of hardship, he notes, from missionaries suppressing its use during colonization to the shift toward large-scale monocultures that crowded out Indigenous staples. The GRAS stamp is a long-overdue validation, he said, of kava’s importance to Hawaiian agriculture and identity. As recognition grows, so have opportunities for small-scale farming initiatives and environmental restoration. By reviving Hawaiian self-sufficiency and healing the scars left by plantations, Trask said, “‘awa [presents] an opportunity to restore our sovereignty and our ancestral connection to the land.” A History of Resilience Polynesian settlers brought kava to Hawai‘i roughly 1,600 years ago, selecting it as a canoe plant—essential crops carried across the Pacific by ancestral voyagers—alongside taro (kalo), breadfruit (‘ulu), and other staples that fed, healed, and built thriving communities across the archipelago. Along with its ceremonial and medicinal role, kava was also an important social drink. Yet by the 19th century, kava was headed toward obscurity. The rise of plantation agriculture uprooted Native communities, replacing local food systems with sprawling sugarcane and pineapple fields. “It’s the same story as all of our Indigenous crops,” said Noa Kekuewa Lincoln, a University of Hawai‘i (UH) associate professor at the College of Tropical Agriculture and Human Resources and head of the Indigenous Cropping Systems Laboratory. Despite these challenges, kava’s ability to thrive in sun, shade, and diverse soils enabled it to persist, mainly in the wild. Forty years ago, Edward Johnston, a leading kava expert and co-founder of the Association for Hawaiian ‘Awa (AHA), stumbled on a hidden patch of kava deep in the Big Island’s Waipi‘o Valley. Struck by its calming properties, he began collecting and propagating different varieties in his back yard, eventually offering them for sale at the newly established Hilo Farmers Market. Since kava reproduces only through cuttings, not seeds, Johnston’s work has been vital to preserving Hawai‘i’s 13 known cultivars. Known as noble varieties, all Hawaiian strains contain balanced levels of kavalactones, the compounds responsible for kava’s calming effects. Through AHA, a non-profit promoting the cultural, educational, and sustainable use of kava, Johnston has helped safeguard these native plants and elevated their cultural significance.

(Photo credit: Edward Johnston) Johnston’s efforts helped spark a kava comeback, riding the wave of the Hawaiian Renaissance, a late-1960s cultural movement to reclaim Native traditions, language, and sovereignty. The resurgence gained further traction in the 1990s with support from the Department of Defense’s Rural Economic Transition Assistance-Hawai‘i grants, which helped farmers shift from sugarcane plantations to diversified agriculture. The late Senator Daniel Inouye (D-Hawai‘i) championed the program amid the decline of the sugarcane industry, spurring about 200 acres of kava cultivation by backyard growers and commercial farms, according to Johnston. Demand for kava soared during this time, especially in Germany, where Hawaiian strains fetched a premium. In a 1998 newsreel, AHA co-founder Jerry Konanui urged farmers to seize the moment, highlighting that the raw kava prices had doubled to $10 a pound, presenting a sustainable source of supplemental income. But when the liver toxicity reports surfaced in 2000, “everything went downhill,” Johnston said. Germany’s 2002 ban left a lasting impact: Despite inclusion in the Codex Alimentarius in 2020, kava is still illegal in Poland, the United Kingdom, and a host of other countries. And in the U.S., the FDA’s 2002 advisory, which labels kava as an unapproved food additive with potential health risks, still rules, lumping traditional preparations together with processed products. A Growing Market Amid Regulatory Ambiguity With federal oversight of kava in a gray zone that allows its use as a supplement, kava bars have popped up across the country over the last decade. Currently, about 180 establishments cater to a growing thirst for the drink as a social tonic and alcohol alternative. As kava’s allure grows, so, too, have local restrictions. In Florida, the so-called “U.S. Kava Capital” and home to 75 kava venues and a small crop of farms, one county recently imposed limits on kava bars near schools (there are no state age regulations around kava consumption). And in New York City, officials shut down a cafe serving kava and kratom, calling the combination “dangerous.” Sampling Kava SafelyThe Hawai‘i Department of Health recommends these guidelines when trying kava: Choose Noble Strains: Always look for kava harvested from noble cultivars—Hawaiian kava is inherently noble—as these are the only strains designated as GRAS. While state production still remains in the hundreds of acres, according to Edward Johnston, several producers sell kava online. Stick to Traditional Preparations: Traditional aqueous extraction methods—using water or coconut water to prepare the beverage—are considered safe and follow long-established cultural practices. Avoid Chemical Extracts: Stay away from adulterated and concentrated kava products, including those made with ethanol and other organic solvents, which can lead to elevated kavalactone levels and increase health risks. Michigan, however, greenlit kava in 2023, becoming the first state to grant it GRAS status. “Michigan relies on the FDA to provide new information on GRAS products,” said a spokesperson for the state’s Department of Agriculture and Rural Development (MDARD), which issued the designation. But in this case, “MDARD believed the WHO document provided sufficient evidence” to confirm the safety of traditionally prepared kava. Soon after, Hawai‘i followed suit, citing the FDA’s “erroneous” classification of kava. The state’s health department invoked a federal exception that grants GRAS status to substances with a proven history of safe use before 1958—a milestone in food safety marked by the Food Additives Amendment. The state ruling recognizes noble kava cultivars brewed with water or coconut water as safe, while warning against alcohol-based extracts and processed products. Although studies have linked kava to elevated liver enzyme levels, research shows that most cases of liver damage involve concentrated extracts or products made with non-root parts, like leaves or stems, rather than traditional brews. Genetics also play a role: While nearly all Pacific Islanders have an enzyme that metabolizes kava safely, upwards of a fifth of Caucasians lack it, increasing their risk of liver toxicity when consuming adulterated kava. In an email to Civil Eats, an FDA spokesperson clarified that, absent GRAS status, kava can’t be used in foods and drinks and must be sold as a dietary supplement. Even though “this determination does not apply to kava steeped in water and consumed as food,” the agency’s warning still stands; “the cultural use of kava does not influence its safety assessment,” added the spokesperson, citing “data gaps” in the WHO evaluation. Yet, as U.H.’s Lincoln notes, by the FDA’s own definition, kava—safely consumed for millennia—should qualify as GRAS. Not recognizing the historical safety of traditional preparations amounts to “[an] erasure of indigenous Hawaiian identity,” he adds, and an act of “ongoing colonial repression.” Ultimately, the regulatory ambiguity creates inconsistent approaches for other agencies, including the Drug Enforcement Administration (DEA). While the DEA doesn’t classify kava as a controlled substance, it lists the root alongside LSD and fentanyl on its Drugs of Abuse list, further muddling its legal status. Adding to the uncertainty, California echoed the FDA’s position last May by issuing its own caution in a consumer fact sheet. Harvesting ‘awa requires leaving the corm and lateral roots intact. (Photo credit: Kanaka Kava) The ambiguity is causing significant challenges for Rami Kayali, who owns two kava bars in California with plans to open a third—‘Awa Hou—in Honolulu this month. After six years of insuring his two mainland establishments, Kayali’s provider abruptly canceled coverage, citing the DEA scrutiny. Kayali has had to scramble, turning to pricey cannabis-industry insurance at nearly triple the cost. “It’s been a nightmare,” he said. Amid these challenges, Hawai‘i’s formal stance provides vital legal footing for the industry, said Trask of Kanaka Kava, at least in the islands. “To have some of those protections put on paper is important.” Yet those protections are weakly enforced. “We conduct investigations when notified,” a DOH spokesperson said, conceding that while state statutes require labeling and compliance, enforcement is largely reactive. “Blasphemous” kava extracts and adulterations are widely available, both on-island and online, said Trask, perpetuating misconceptions about “‘awa done traditionally,” prepared with just water or coconut water. Supporting Local and Sustainable Kava Production Nevertheless, the GRAS designation is opening new doors for kava entrepreneurs and farmers alike. A recent $70,000 state grant aims to boost sustainable kava production and reduce Hawai‘i’s reliance on food imports, which currently hovers at around 85 percent of the state’s total food supply. And the economic potential is clear: In Vanuatu, kava makes up 75 percent of exports, generating nearly $50 million a year for the remote South Pacific island nation. Hawai‘i’s noble kava varieties fetch premium prices—fresh “wet” kava can retail for $64 a pound—though local production remains “microscopic,” said Taesali of Kava Queen in O‘ahu. Her bar, like many in the U.S., serves mainly Fijian and Vanuatuan kava. Scaling up won’t be easy, as kava plants take a few years to establish, and the slow returns can deter farmers. Growers like Trask of the farm-to-table Kanaka Kava, however, are tackling these hurdles by creating regional hubs and kava farm networks. “We’re building a place-based community model of production,” Trask said, helping farmers grow cultivars suited to local microclimates, offering harvest support, and buying back crops in three to five years. For Trask, kava is also central to healing Hawai‘i’s post-plantation scars. Fertile rainforests were razed for sugarcane fields, then abandoned after the industry’s collapse in the 1990s. Now overrun with “acres and acres of pasture and eucalyptus,” the land faces threats from pests and wildfires. By integrating native trees such as breadfruit and morinda (noni) with kava, taro, and other canoe plants, “we’re rebuilding our agroforestry system,” he said. Doing so “restores pono,” he adds, using a Hawaiian expression for the reestablishment of balance in the soil, in biodiversity, and in cultural practices. Still, U.H,’s Lincoln is wary of kava becoming another commodity crop, where profits flow up, not down. “Hawai‘i is a state of small farms,” he said, with more than 90 percent measuring less than 50 acres. Aggregators and marketers tend to dominate supply chains, however, siphoning revenue and squeezing out small-scale growers. Kona coffee beans are a prime example: While beans retail upwards of $80 a pound, farmers, on average, earn just $2.25 per pound of cherries. Lincoln sees co-ops as a promising model. His wife, Dana Shapiro, heads the Hawaiʻi ʻUlu Cooperative, which has helped revitalize breadfruit as an island staple. Co-ops allow farmers to “increase their equity and power,” he said, through collective control over aggregation, processing, and marketing. That results in fairer prices, higher profits, and greater “‘āina”—land stewardship practices like agroforestry and crop rotation that nurture both the land and local food system. Trask echoes the sentiment. As demand for kava grows, restoring pono means honoring kava from soil to cup. “It’s about cultivating more farmers—and more [informed] consumers,” he said, to ensure that this ancient crop once again thrives.

The UK’s advertising watchdog has upheld a complaint that Britain’s biggest farm assurance scheme misled the public in a TV ad about its environmental standards.The Red Tractor scheme, used by leading supermarkets including Tesco, Asda and Morrisons to assure customers their food meets high standards for welfare, environment, traceability and safety, is the biggest and perhaps best known assurance system in Britain.About 45,000 of the UK’s farms are members of the scheme, and the advert promised that food carrying the logo had been “farmed with care”.But the Advertising Standards Authority (ASA) upheld a complaint from the clean water campaign group River Action that the scheme’s environmental standards were exaggerated in the advert, last aired in 2023.In its judgment, the ASA said the ad must not be shown again in its current form. It said in future Red Tractor should make clear exactly what standards it is referring to when it uses the phrases “farmed with care” and “all our standards are met”.River Action said it made the complaint because it was concerned environmental standards relating to pollution were not being met on Red Tractor farms, including the claim “When the Red Tractor’s there, your food’s farmed with care … from field to store all our standards are met.”The ASA considered evidence from an Environment Agency report into Red Tractor farms, which found that 62% of the most critical pollution incidents occurred on Red Tractor farms between 2014 and 2019.Charles Watson, chair and founder of River Action, said large food retailers such as Tesco and Asda should lay out credible plans as to how they would move away from what he termed a “busted flush” of a certification scheme and instead support farmers whose working practices were genuinely sustainable.“Red Tractor farms are polluting the UK’s rivers, and consumers trying to make environmentally responsible choices have been misled,” said Watson.“This ASA ruling confirms what we’ve long argued: Red Tractor’s claims aren’t just misleading – they provide cover for farms breaking the law.”Red Tractor said its standards did not cover all environmental legislation. Therefore, data on compliance with environmental regulation should not be confused with farms’ compliance with Red Tractor’s requirements.Jim Moseley, CEO of Red Tractor, said: “We believe the ASA’s final decision is fundamentally flawed and misinterprets the content of our advert.“If the advert was clearly misleading, it wouldn’t have taken so long to reach this conclusion. Accordingly, the ASA’s actions are minimal. They’ve confirmed that we can continue to use ‘farmed with care’ but simply need to provide more information on the specific standards being referred to.“The advert … made no environmental claim, and we completely disagree with the assumption that it would have been misinterpreted by consumers.”

Can you really be addicted to food? Researchers uncover convincing similarities to drug addiction

Hundreds of studies have confirmed that certain foods affect the brain similarly to other addictive substances

People often joke that their favorite snack is “like crack” or call themselves “chocoholics” in jest. But can someone really be addicted to food in the same way they could be hooked on substances such as alcohol or nicotine? As an addiction psychiatrist and researcher with experience in treating eating disorders and obesity, I have been following the research in this field for the past few decades. I have written a textbook on food addiction, obesity and overeating disorders, and, more recently, a self-help book for people who have intense cravings and obsessions for some foods. While there is still some debate among psychologists and scientists, a consensus is emerging that food addiction is a real phenomenon. Hundreds of studies have confirmed that certain foods – often those that are high in sugar and ultraprocessed – affect the brains and behavior of certain people similarly to other addictive substances such as nicotine. Still, many questions remain about which foods are addictive, which people are most susceptible to this addiction and why. There are also questions as to how this condition compares to other substance addictions and whether the same treatments could work for patients struggling with any kind of addiction. How does addiction work? The neurobiological mechanisms of addiction have been mapped out through decades of laboratory-based research using neuroimaging and cognitive neuroscience approaches. Studies show that preexisting genetic and environmental factors set the stage for developing an addiction. Regularly consuming an addictive substance then causes a rewiring of several important brain systems, leading the person to crave more and more of it. This rewiring takes place in three key brain networks that correspond to key functional domains, often referred to as the reward system, the stress response system and the system in charge of executive control. First, using an addictive substance causes the release of a chemical messenger called dopamine in the reward network, which makes the user feel good. Dopamine release also facilitates a neurobiological process called conditioning, which is basically a neural learning process that gives rise to habit formation. As a result of the conditioning process, sensory cues associated with the substance start to have increasing influence over decision-making and behavior, often leading to a craving. For instance, because of conditioning, the sight of a needle can drive a person to set aside their commitment to quit using an injectable drug and return to it. Second, continued use of an addictive substance over time affects the brain’s emotional or stress response network. The user’s body and mind build up a tolerance, meaning they need increasing amounts of the substance to feel its effect. The neurochemicals involved in this process are different than those mediating habit formation and include a chemical messenger called noradrenaline and internally produced opioids such as endorphins. If they quit using the substance, they experience symptoms of withdrawal, which can range from irritability and nausea to paranoia and seizures. At that point, negative reinforcement kicks in. This is the process by which a person keeps going back to a substance because they’ve learned that using the substance doesn’t just feel good, but it also relieves negative emotions. During withdrawal from a substance, people feel profound emotional discomfort, including sadness and irritability. Negative reinforcement is why someone who is trying to quit smoking, for instance, will be at highest risk of relapse in the week just after stopping and during times of stress, because in the past they’d normally turn to cigarettes for relief. Third, overuse of most addictive substances progressively damages the brain’s executive control network, the prefrontal cortex, and other key parts of the brain involved in impulse control and self-regulation. Over time, the damage to these areas makes it more and more difficult for the user to control their behavior around these substances. This is why it is so hard for long-term users of many addictive substances to quit. Scientists have learned more about what’s happening in a person’s brain when they become addicted to a substance. What evidence is there that food is addictive? Many studies over the past 25 years have shown that high-sugar and other highly pleasurable foods – often foods that are ultraprocessed – act on these brain networks in ways that are similar to other addictive substances. The resulting changes in the brain fuel further craving for and overuse of the substance – in this case, highly rewarding food. Clinical studies have demonstrated that people with an addictive relationship to food demonstrate the hallmark signs of a substance use disorder. Studies also indicate that for some people, cravings for highly palatable foods go well beyond just a normal hankering for a snack and are, in fact, signs of addictive behavior. One study found that cues associated with highly pleasurable foods activate the reward centers in the brain, and the degree of activation predicts weight gain. In other words, the more power the food cue has to capture a person’s attention, the more likely they are to succumb to cravings for it. Multiple studies have also found that suddenly ending a diet that’s high in sugar can cause withdrawal, similar to when people quit opioids or nicotine. Excessive exposure to high-sugar foods has also been found to reduce cognitive function and cause damage to the prefrontal cortex and hippocampus, the parts of the brain that mediate executive control and memory. In another study, when obese people were exposed to food and told to resist their craving for it by ignoring it or thinking about something else, their prefrontal cortexes were more active compared with nonobese individuals. This indicates that it was more difficult for the obese group to fight their cravings. Researchers are still working out the best methods to help patients with food addictions develop a healthy relationship with food. Viktar Sarkisian/iStock via Getty Images Plus Finding safe treatments for patients struggling with food Addiction recovery is often centered on the idea that the fastest way to get well is to abstain from the problem substance. But unlike nicotine or narcotics, food is something that all people need to survive, so quitting cold turkey isn’t an option. In addition, eating disorders such as bulimia nervosa and binge-eating disorder often occur alongside addictive eating. Most psychologists and psychiatrists believe these illnesses have their root cause in excessive dietary restriction. For this reason, many eating disorder treatment professionals balk at the idea of labeling some foods as addictive. They are concerned that encouraging abstinence from particular foods could trigger binge eating and extreme dieting to compensate. A way forward But others argue that, with care, integrating food addiction approaches into eating disorders treatment is feasible and could be lifesaving for some. The emerging consensus around this link is moving researchers and those who treat eating disorders to consider food addiction in their treatment models. One such approach might look like the one described to me by addiction psychiatrist and eating disorders specialist Dr. Kim Dennis. In line with traditional eating disorder treatment, nutritionists at her residential clinic strongly discourage their patients from restricting calories. At the same time, in line with traditional addiction treatment, they help their patients to consider significantly reducing or completely abstaining from particular foods to which they have developed an addictive relationship. Additional clinical studies are already being carried out. But going forward, more studies are needed to help clinicians find the most effective treatments for people with an addictive relationship with food. Efforts are underway by groups of psychologists, psychiatrists, neuroscientists and mental health providers to get “ultraprocessed food use disorder,” also known as food addiction, into future editions of diagnostic manuals such as the Diagnostic and Statistical Manual of Mental Disorders and the World Health Organization’s International Classification of Diseases. Beyond acknowledging what those treating food addiction are already seeing in the field, this would help researchers get funding for additional studies of treating food addiction. With more information about what treatments will work best for whom, those who have these problems will no longer have to suffer in silence, and providers will be better equipped to help them.   Claire Wilcox, Adjunct Faculty in Psychiatry, University of New Mexico This article is republished from The Conversation under a Creative Commons license.

Newsom signs first-in-nation law to ban ultraprocessed food in school lunches 

California health officials will now decide which ingredients, additives, dyes, and other forms of processing don’t belong in school meals and K-12 cafeterias.

In summary California health officials will now decide which ingredients, additives, dyes, and other forms of processing don’t belong in school meals and K-12 cafeterias. California is the first state in the country to ban ultraprocessed foods from school meals, aiming to transform how children eat on campus by 2035.  In the cafeteria of Belvedere Middle School in the Los Angeles neighborhood of Boyle Heights, Gov. Gavin Newsom signed a measure that requires K-12 schools to phase out foods with potentially harmful ultraprocessed ingredients over the next 10 years. The requirements go above and beyond existing state and federal school nutrition standards for things like fat and calorie content in school meals. California public schools serve nearly 1 billion meals to kids each year. “Our first priority is to protect kids in California schools, but we also came to realize that there is huge market power here,” said Assemblymember Jesse Gabriel, an Encino Democrat. “This bill could have impacts far beyond the classroom and far beyond the borders of our state.” The legislation builds on recent laws passed in California to eliminate synthetic food dyes from school meals and certain additives from all food sold in the state when they are associated with cancer, reproductive harm and behavioral problems in children. Dozens of other states have since replicated those laws.  The bipartisan measure also comes at a time when U.S. Health and Human Services Secretary Robert F. Kennedy, Jr.’s “Make America Healthy Again” movement has shone a spotlight on issues including chronic disease, childhood obesity and poor diet.  The term “ultra-processed food” appears more than three dozen times in the MAHA report on children’s health released in May. A subsequent MAHA strategy report tasks the federal government with defining ultraprocessed food. California’s new law beats them to the punch, outlining the first statutory definition of what makes a food ultraprocessed. It identifies ingredients that characterize ultraprocessed foods, including artificial flavors and colors, thickeners and emulsifiers, non-nutritive sweeteners, and high levels of saturated fat, sodium or sugar. Often fast food, candy and premade meals include these ingredients. Researchers say ultraprocessed foods tend to be high in calories and low in nutritional value. Studies have linked consumption of ultraprocessed foods with obesity. Today, one in five children is obese.  Ultraprocessed foods are also linked to increased cancer risk, cardiovascular disease and diabetes. Studies have found sweetened beverages and processed meats to be particularly harmful, said Tasha Stoiber, a senior scientist at the Environmental Work Group, which sponsored the legislation. Kids are particularly susceptible to the effects of ultraprocessed foods, she said. “Ultraprocessed foods are also marketed heavily to kids with bright colors, artificial flavors, hyperpalatability,” Stoiber said. “The hallmarks of ultraprocessed foods are a way to sell and market more product.” Gabriel said lawmakers and parents have become “much more aware of how what we feed our kids impacts their physical health, emotional health and overall well-being.” That has helped generate strong bipartisan support for the law, which all but one Republican in the state Legislature supported.  A coalition of business interests representing farmers, grocers, and food and beverage manufacturers opposed it. They argued the definition of ultraprocessed food was still too broad and ran the risk of stigmatizing harmless processed foods like canned fruits and vegetables that include preservatives. Vegetarian meat substitutes also generally contain things like processed soy protein and binders that may run afoul of the definition. Gabriel contends that the law bans not foods but rather harmful ingredients. The California Department of Public Health now must identify ultraprocessed ingredients that may be associated with poor health outcomes. Schools will no longer allow those ingredients in meals, and vendors could replace them with healthier options, Gabriel said.

Immune-informed brain aging research offers new treatment possibilities, speakers say

Speakers at MIT’s Aging Brain Initiative symposium described how immune system factors during aging contribute to Alzheimer’s, Parkinson’s and other conditions. The field is leveraging that knowledge to develop new therapies.

Understanding how interactions between the central nervous system and the immune system contribute to problems of aging, including Alzheimer’s disease, Parkinson’s disease, arthritis, and more, can generate new leads for therapeutic development, speakers said at MIT’s symposium “The Neuro-Immune Axis and the Aging Brain” on Sept 18.“The past decade has brought rapid progress in our understanding of how adaptive and innate immune systems impact the pathogenesis of neurodegenerative disorders,” said Picower Professor Li-Huei Tsai, director of The Picower Institute for Learning and Memory and MIT’s Aging Brain Initiative (ABI), in her introduction to the event, which more than 450 people registered to attend. “Together, today’s speakers will trace how the neuro-immune axis shapes brain health and disease … Their work converges on the promise of immunology-informed therapies to slow or prevent neurodegeneration and age-related cognitive decline.”For instance, keynote speaker Michal Schwartz of the Weizmann Institute in Israel described her decades of pioneering work to understand the neuro-immune “ecosystem.” Immune cells, she said, help the brain heal, and support many of its functions, including its “plasticity,” the ability it has to adapt to and incorporate new information. But Schwartz’s lab also found that an immune signaling cascade can arise with aging that undermines cognitive function. She has leveraged that insight to investigate and develop corrective immunotherapies that improve the brain’s immune response to Alzheimer’s both by rejuvenating the brain’s microglia immune cells and bringing in the help of peripheral immune cells called macrophages. Schwartz has brought the potential therapy to market as the chief science officer of ImmunoBrain, a company testing it in a clinical trial.In her presentation, Tsai noted recent work from her lab and that of computer science professor and fellow ABI member Manolis Kellis showing that many of the genes associated with Alzheimer’s disease are most strongly expressed in microglia, giving it an expression profile more similar to autoimmune disorders than to many psychiatric ones (where expression of disease-associated genes typically is highest in neurons). The study showed that microglia become “exhausted” over the course of disease progression, losing their cellular identity and becoming harmfully inflammatory.“Genetic risk, epigenomic instability, and microglia exhaustion really play a central role in Alzheimer’s disease,” Tsai said, adding that her lab is now also looking into how immune T cells, recruited by microglia, may also contribute to Alzheimer’s disease progression.The body and the brainThe neuro-immune “axis” connects not only the nervous and immune systems, but also extends between the whole body and the brain, with numerous implications for aging. Several speakers focused on the key conduit: the vagus nerve, which runs from the brain to the body’s major organs.For instance, Sara Prescott, an investigator in the Picower Institute and an MIT assistant professor of biology, presented evidence her lab is amassing that the brain’s communication via vagus nerve terminals in the body’s airways is crucial for managing the body’s defense of respiratory tissues. Given that we inhale about 20,000 times a day, our airways are exposed to many environmental challenges, Prescott noted, and her lab and others are finding that the nervous system interacts directly with immune pathways to mount physiological responses. But vagal reflexes decline in aging, she noted, increasing susceptibility to infection, and so her lab is now working in mouse models to study airway-to-brain neurons throughout the lifespan to better understand how they change with aging.In his talk, Caltech Professor Sarkis Mazmanian focused on work in his lab linking the gut microbiome to Parkinson’s disease (PD), for instance by promoting alpha-synuclein protein pathology and motor problems in mouse models. His lab hypothesizes that the microbiome can nucleate alpha-synuclein in the gut via a bacterial amyloid protein that may subsequently promote pathology in the brain, potentially via the vagus nerve. Based on its studies, the lab has developed two interventions. One is giving alpha-synuclein overexpressing mice a high-fiber diet to increase short-chain fatty acids in their gut, which actually modulates the activity of microglia in the brain. The high-fiber diet helps relieve motor dysfunction, corrects microglia activity, and reduces protein pathology, he showed. Another is a drug to disrupt the bacterial amyloid in the gut. It prevents alpha synuclein formation in the mouse brain and ameliorates PD-like symptoms. These results are pending publication.Meanwhile, Kevin Tracey, professor at Hofstra University and Northwell Health, took listeners on a journey up and down the vagus nerve to the spleen, describing how impulses in the nerve regulate immune system emissions of signaling molecules, or “cytokines.” Too great a surge can become harmful, for instance causing the autoimmune disorder rheumatoid arthritis. Tracey described how a newly U.S. Food and Drug Administration-approved pill-sized neck implant to stimulate the vagus nerve helps patients with severe forms of the disease without suppressing their immune system.The brain’s borderOther speakers discussed opportunities for understanding neuro-immune interactions in aging and disease at the “borders” where the brain’s and body’s immune system meet. These areas include the meninges that surround the brain, the choroid plexus (proximate to the ventricles, or open spaces, within the brain), and the interface between brain cells and the circulatory system.For instance, taking a cue from studies showing that circadian disruptions are a risk factor for Alzheimer’s disease, Harvard Medical School Professor Beth Stevens of Boston Children’s Hospital described new research in her lab that examined how brain immune cells may function differently around the day-night cycle. The project, led by newly minted PhD Helena Barr, found that “border-associated macrophages” — long-lived immune cells residing in the brain’s borders — exhibited circadian rhythms in gene expression and function. Stevens described how these cells are tuned by the circadian clock to “eat” more during the rest phase, a process that may help remove material draining from the brain, including Alzheimer’s disease-associated peptides such as amyloid-beta. So, Stevens hypothesizes, circadian disruptions, for example due to aging or night-shift work, may contribute to disease onset by disrupting the delicate balance in immune-mediated “clean-up” of the brain and its borders.Following Stevens at the podium, Washington University Professor Marco Colonna traced how various kinds of macrophages, including border macrophages and microglia, develop from the embryonic stage. He described the different gene-expression programs that guide their differentiation into one type or another. One gene he highlighted, for instance, is necessary for border macrophages along the brain’s vasculature to help regulate the waste-clearing cerebrospinal fluid (CSF) flow that Stevens also discussed. Knocking out the gene also impairs blood flow. Importantly, his lab has found that versions of the gene may be somewhat protective against Alzheimer’s, and that regulating expression of the gene could be a therapeutic strategy.Colonna’s WashU colleague Jonathan Kipnis (a former student of Schwartz) also discussed macrophages that are associated with the particular border between brain tissue and the plumbing alongside the vasculature that carries CSF. The macrophages, his lab showed in 2022, actively govern the flow of CSF. He showed that removing the macrophages let Alzheimer’s proteins accumulate in mice. His lab is continuing to investigate ways in which these specific border macrophages may play roles in disease. He’s also looking in separate studies of how the skull’s brain marrow contributes to the population of immune cells in the brain and may play a role in neurodegeneration.For all the talk of distant organs and the brain’s borders, neurons themselves were never far from the discussion. Harvard Medical School Professor Isaac Chiu gave them their direct due in a talk focusing on how they participate in their own immune defense, for instance by directly sensing pathogens and giving off inflammation signals upon cell death. He discussed a key molecule in that latter process, which is expressed among neurons all over the brain.Whether they were looking within the brain, at its border, or throughout the body, speakers showed that age-related nervous system diseases are not only better understood but also possibly better treated by accounting not only for the nerve cells, but their immune system partners. 

The hidden cost of ultra-processed foods on the environment: ‘The whole industry should pay’

Industrially made foods involve several ingredients and processes to put together, making it difficult to examine their true costIf you look at a package of M&Ms, one of the most popular candies in the US, you’ll see some familiar ingredients: sugar, skimmed milk powder, cocoa butter. But you’ll see many more that aren’t so recognizable: gum arabic, dextrin, carnauba wax, soya lecithin and E100.There are 34 ingredients in M&Ms, and, according to Mars, the company that produces the candy, at least 30 countries – from Ivory Coast to New Zealand – are involved in supplying them. Each has its own supply chain that transforms the raw materials into ingredients – cocoa into cocoa liquor, cane into sugar, petroleum into blue food dye. Continue reading...

If you look at a package of M&Ms, one of the most popular candies in the US, you’ll see some familiar ingredients: sugar, skimmed milk powder, cocoa butter. But you’ll see many more that aren’t so recognizable: gum arabic, dextrin, carnauba wax, soya lecithin and E100.There are 34 ingredients in M&Ms, and, according to Mars, the company that produces the candy, at least 30 countries – from Ivory Coast to New Zealand – are involved in supplying them. Each has its own supply chain that transforms the raw materials into ingredients – cocoa into cocoa liquor, cane into sugar, petroleum into blue food dye.These ingredients then travel across the world to a central processing facility where they are combined and transformed into tiny blue, red, yellow and green chocolate gems.It’s becoming better understood that food systems are a major driver of the climate crisis. Scientists can examine deforestation for agriculture, or the methane emissions from livestock. But the environmental impact of ultra-processed foods – like M&Ms – is less clear and is only now starting to come into focus. One reason they have been so difficult to assess is the very nature of UPFs: these industrially made foods include a huge number of ingredients and processes to put them together, making it nearly impossible to track.But it doesn’t mean it’s not important. As UPFs take over US grocery store shelves and diets– they now comprise 70% of food sold in grocery stores, and more than half of calories consumed – experts say that understanding their environmental toll is critical to build a more climate-friendly food system.What we knowWhile scientists are only starting to examine the environmental impact of UPFs, what’s already known about them is worrisome.“The more processed foods are, the more deleterious they are to human health and the environment,” said Anthony Fardet, a senior researcher at the French National Institute for Agriculture, Food and the Environment. The main reason, he explains, is that the ingredients are so energy intensive. When combined, the toll balloons.Take M&Ms. The first step in creating the candies is farming for cocoa, sugar, dairy and palm.It has been well-documented that agriculture for ingredients like cocoa drives ever increasing rates of deforestation across the globe. Since 1850, agricultural expansion has driven almost 90% of global deforestation, which has been responsible for 30% of global greenhouse gas emissions. Mars corporation has been called out in the past for the cocoa farming practices in their supply chain, and have since created sustainability plans, but these fail to address that large-scale agricultural practices like cocoa farming are, at their core, unsustainable.Then there’s sugar, milk solids and palm fat – also major greenhouse gas emitters.On top of that are the industrially made ingredients like food dyes – perhaps the signature of ultra-processing – which M&Ms contain 13 different types of. Blue M&Ms are colored with dyes E132 and E133; these dyes are mostly made in food dye manufacturing hotspots India and China, via a chemical reaction of aromatic hydrocarbons (which are petroleum products) with diazonium salt, catalyzed by the metals copper and chromium.M&Ms for sale in Orlando, Florida, in 2019. Photograph: Jeff Greenberg/Universal Images Group via Getty ImagesCreating soya lecithin, an additive made from soybean oil that’s used to change the consistency of chocolate, requires steps like degumming in a hot reactor, chemically isolating phospholipids, decolorization using hydrogen peroxide and drying under vacuum pressure. And dextrose, a sweetener, starts off as corn that gets steeped in acid before being milled, separated and dried. From there, it’s broken down into smaller molecules using enzymes and acids, and then recrystallized.Mars declined to comment for this story.While ultra-processed chocolate products are some of the worst offenders, other kinds of UPFs are taxing on the environment as well. Take for instance Doritos, which have 39 ingredients. Corn is the main ingredient, and for every acre grown, 1,000kg of carbon dioxide is emitted to the atmosphere. Like Mars, Pepsico, which makes Doritos, has developed its own sustainability promises, but many of these promises are underpinned by practices that are considered greenwashing, like “regenerative agriculture”. In reality, these sustainability promises undercut the dire need to better understand how UPFs affect our global climate.As a result, some experts have started to calculate the environmental toll of UPFs.CarbonCloud, a Sweden-based software company that calculates the emissions of food products, analyzed carbon disclosures from Mars, and estimated that M&Ms generate at least 13.2kg of carbon equivalents per kilogram of M&Ms produced. Mars produces more than 664m kg of M&Ms in the US each year, which would mean that if CarbonCloud’s calculations are accurate, the candies emit at least 3.8m tons of carbon dioxide – making up 0.1% of annual emissions in the US. (Mars does not report emissions by product, but according to their 2024 emissions report, they emitted 29m tons of carbon dioxide across the company.)But this is only an estimate based on publicly available data; the true cost is probably much higher, experts say. There’s a “black box” when it comes to carbon accounting in the processed food industry, says Patrick Callery, a professor at the University of Vermont who researches how corporations engage with the climate crisis. “There is so much uncertainty as supply chains get complex.”What we don’t knowGetting an exact measure of the environmental toll of UPFs is nearly impossible, given that, definitionally, UPFs consist of many ingredients and a high volume of opaque processes. Ingredients aren’t just mixed together like one would do to make a stew at home. Instead, these ingredients are chemically modified, some parts stripped away, and flavors, dyes or textures added in – and it’s unclear what the cost of these processes are because so many suppliers and components are involved.Another reason is that all UPFs (again, definitionally) are the creations of food companies that have little incentive to disclose their environmental footprint and may not fully understand it to begin with.For instance, Mars itself doesn’t farm cocoa, but instead relies on hundreds of farms that don’t always have accurate carbon accounting measures in place. This means that emissions from big food corporations may be underreported. David Bryngelsson, co-founder of CarbonCloud, said that corporations “don’t have actual data, so they use emissions factors, which are guesses”.Callery says that corporations provide reports on simple things like transportation, which are easier to calculate, and often omit or convolute the agricultural emissions of their product. After all, reporting high emissions goes against the interests of large food corporations, so the complex calculations needed to determine the carbon footprint of large-scale agriculture and multi-step industrial chemical processes used to make UPF ingredients remain un-researched.“The main point of ultra-processed foods is money,” said Fardet, pointing out that they’re designed to be attractive, easy and pleasurable to eat.“Most of the people in the [food industry’s] value chain don’t care about climate change from an ideological point of view, but they do care about money,” said Bryngelsson. He explains that to shift those incentives, the value of foods and ingredients would need to incorporate their impact on our shared climate. But that would require government regulations and financial penalties based on the true environmental cost of UPFs, says Bryngelsson.Why it mattersAt just under $2, the price of M&Ms at the grocery store hardly reflects their true cost on the environment. But to address these problems with ultra-processed foods, more than just a few tweaks to the ingredient list are needed.“Reducing the salt, or sugar of just one product is just greenwashing,” said Fardet. “We need to change the whole picture.” To do that, he suggested consuming more locally sourced, whole foods, which often take much less energy and transit to produce, and therefore have a much smaller carbon footprint.Specialty goods that can’t be sourced locally, like chocolate, should make up a small fraction of our diet and come from traceable and ethical supply chains.That’s not easy for all Americans, given the rising cost of food and the prevalence of food deserts and mediocre food retailers across the US.That’s why it can’t just be up to individuals to make environmentally (and health) conscious choices, experts say. Instead, large food corporations need to be held responsible for the burden they place on society – particularly as it pertains to climate change. Sustainability practices, like the “Cocoa for Generations” plan outlined by Mars, or Pepsico’s “Pep+” initiatives are Band-Aids on broken bones. Large food corporations need to be phased out to make global food systems sustainable.But perhaps more important is to change our understanding of the hidden costs of ultra-processed foods, says Fardet, whether it’s at home, in schools or through the banning the marketing of UPFs to children. Our food systems, Fardet said, “are absolutely not normal. The whole industry should pay the hidden costs.”
