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.

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.

Trump Administration Plans Ban on More Synthetic Food Dyes

TUESDAY, April 22, 2025 (HealthDay News) — The Trump administration is expected to take new steps to remove artificial food dyes from the U.S. food supply, officials say.This follows a major move by the U.S. Food and Drug Administration (FDA) in January, under former President Joe Biden, to ban red dye No. 3 in food, drinks and some drugs. That action came more than 30 years after research linked the dye to cancer in animals.Now, federal officials appear ready to go even farther. Kennedy has been an outspoken critic of petroleum-based synthetic dyes, which are used to make foods and drinks look more appealing to consumers.In March, Kennedy supported a new West Virginia law banning some of these dyes. It made West Virginia the first state to take such broad action. Studies have linked some food dyes to behavior and learning issues in children, CNN reported.More than half of U.S. states, including both Republican- and Democrat-led ones, are pushing to restrict these ingredients, according to the Environmental Working Group (EWG).In a March email to CNN, the National Confectioners Association said while states have a role to play in the nation's food system, "the FDA is the rightful national regulatory decision maker and leader in food safety." Some of the association's members sell products that contain artificial dyes.John Hewitt of the Consumer Brands Association also urged the FDA to take the lead, saying the agency should “aggressively acknowledge its responsibility as the nation’s food safety regulator.”Artificial dyes such as red No. 3, red No. 40, green No. 3 and blue No. 2 have been linked to cancer or tumors in animals. Others, like yellow No. 5 and yellow No. 6, may contain cancer-causing chemicals. Even tiny amounts of yellow No. 5 can cause restlessness or sleep problems in sensitive children, CNN reported.Marion Nestle, a well-known food policy expert, welcomed the plan.“Non-petroleum substitute dyes are available and used widely in other countries by the same companies that sell products here," she said. "Companies have been promising to get rid of the petroleum dyes for years. The time has come.”In public health terms, “this is low-hanging fruit," Nestle added. "I want to see RFK Jr. take on ultra-processed foods, a much tougher problem and a far more important one.”Most of these dyes are used in low-nutrition foods like candy and soda, but they may also appear in less colorful products, the Center for Science in the Public Interest says.People who want to avoid these dyes can check ingredient labels on food and drink packaging, CNN said.SOURCE: CNN, April 22, 2025Copyright © 2025 HealthDay.

Mission to boldly grow food in space labs blasts off

The mission will explore new ways of reducing the cost of feeding an astronaut.

Mission to boldly grow food in space labs blasts offBBC NewsArtwork: The experiment will orbit the Earth for three hours before returning to Earth and splashing down off the coast of PortugalSteak, mashed potatoes and deserts for astronauts could soon be grown from individual cells in space if an experiment launched into orbit today is successful.A European Space Agency (ESA) project is assessing the viability of growing so-called lab-grown food in the low gravity and higher radiation in orbit and on other worlds.ESA is funding the research to explore new ways of reducing the cost of feeding an astronaut, which can cost up to £20,000 per day.The team involved say the experiment is a first step to developing a small pilot food production plant on the International Space Station in two years' time.Lab-grown food will be essential if Nasa's objective of making humanity a multi-planetary species were to be realised, claims Dr Aqeel Shamsul, CEO and founder of Bedford-based Frontier Space, which is developing the concept with researchers at Imperial College, London."Our dream is to have factories in orbit and on the Moon," he told BBC News."We need to build manufacturing facilities off world if we are to provide the infrastructure to enable humans to live and work in space".NASAAstronauts enjoy eating in zero gravity, but the freeze-dried food itself is not much fun to eatLab-grown food involves growing food ingredients, such as protein, fat and carbohydrates in test tubes and vats and then processing them to make them look and taste like normal food.Lab-grown chicken is already on sale in the US and Singapore and lab grown steak is awaiting approval in the UK and Israel. On Earth, there are claimed environmental benefits for the technology over traditional agricultural food production methods, such as less land use and reduced greenhouse gas emissions. But in space the primary driver of is to reduce costs.The researchers are doing the experiment because it costs so much to send astronauts food on the ISS - up to £20,000 per astronaut per day, they estimate. Nasa, other space agencies and private sector firms plan to have a long-term presence on the Moon, in orbiting space stations and maybe one day on Mars. That will mean sending up food for tens and eventually hundreds of astronauts living and working in space – something that would be prohibitively expensive if it were sent up by rockets, according to Dr Shamsul.Growing food in space would make much more sense, he suggests."We could start off simply with protein-enhanced mashed potatoes on to more complex foods which we could put together in space," he tells me."But in the longer term we could put the lab-grown ingredients into a 3D printer and print off whatever you want on the space station, such as a steak!"Lab-grown steak can be produced on Earth, but can it be created in space?This sounds like the replicator machines on Star Trek, which are able to produce food and drink from pure energy. But it is no longer the stuff of science fiction, says Dr Shamsul.He showed me a set-up, called a bioreactor, at Imperial College's Bezos Centre for Sustainable Proteins in west London. It comprised a brick-coloured concoction bubbling away in a test tube. The process is known as precision fermentation, which is like the fermentation used to make beer, but different: "precision" is a rebranding word for genetically engineered.In this case a gene has been added to yeast to produce extra vitamins, but all sorts of ingredients can be produced in this way, according to Dr Rodrigo Ledesma-Amaro, Director of the Bezos Centre."We can make all the elements to make food," says Dr Ledesma-Amaro proudly."We can make proteins, fats, carbohydrates, fibres and they can be combined to make different dishes."The brick-coloured "food" is grown in a small biorector, a mini-version of which has been sent into space A much smaller, simpler version of the biorector has been sent into space on a SpaceX Falcon 9 rocket as part of the ESA mission. There is plenty of evidence that that foods can be successfully grown from cells on Earth, but can the process be repeated in the weightlessness and higher radiation of space?Drs Ledesma-Amaro and Shamsul have sent small amounts of the yeast concoction to orbit the Earth in a small cube satellite on board Europe's first commercial returnable spacecraft, Phoenix. If all goes to plan, it will orbit the Earth for around three hours before falling back to Earth off the coast of Portugal. The experiment will be retrieved by a recovery vessel and sent back to the lab in London to be examined.The data they gather will inform the construction of a larger, better bioreactor which the scientists will send into space next year, according to Dr Ledesma-Amaro.The problem, though, is that the brick-coloured goo, which is dried into a powder, looks distinctly unappetising – even less appetising than the freeze-dried fare that astronauts currently have to put up with.That is where Imperial College's master chef comes in. Jakub Radzikowski is the culinary education designer tasked with turning chemistry into cuisine.Kevin ChurchImperial College's master chef has the job of making lab-grown chemicals into delicious dishesHe isn't allowed to use lab grown ingredients to make dishes for people just yet, because regulatory approval is still pending. But he's getting a head start. For now, instead of lab-grown ingredients, Jakub is using starches and proteins from naturally occurring fungi to develop his recipes. He tells me all sorts of dishes will be possible, once he gets the go-ahead to use lab-grown ingredients."We want to create food that is familiar to astronauts who are from different parts of the world so that it can provide comfort."We can create anything from French, Chinese, Indian. It will be possible to replicate any kind of cuisine in space."Today, Jakub is trying out a new recipe of spicy dumplings and dipping sauce. He tells me that I am allowed to try it them out, but taster-in-chief is someone far more qualified: Helen Sharman, the UK's first astronaut, who also has a PhD in chemistry.Kevin Church/BBC NewsBritain's first astronaut, Helen Sharman and I taste test what might be the space food of the futureWe tasted the steaming dumplings together. My view: "They are absolutely gorgeous!"Dr Sharman's expert view, not dissimilar: "You get a really strong blast from the flavour. It is really delicious and very moreish," she beamed."I would love to have had something like this. When I was in space, I had really long-life stuff: tins, freeze dried packets, tubes of stuff. It was fine, but not tasty."Dr Sharman's more important observation was about the science. Lab-grown food, she said, could potentially be better for astronauts, as well as reduce costs to the levels required to make long-term off-world habitation viable.Research on the ISS has shown that the biochemistry of astronauts' bodies changes during long duration space missions: their hormone balance and iron levels alter, and they we lose calcium from their bones. Astronauts take supplements to compensate, but lab-grown food could in principle be tweaked with the extra ingredients already built in, says Dr Sharman."Astronauts tend to lose weight because they are not eating as much because they don't have the variety and interest in their diet," she told me."So, astronauts might be more open to having something that has been cooked from scratch and a feeling that you are really eating wholesome food."

Microplastics Make It into Your Food through Plant Leaves

New evidence shows plant leaves absorb airborne microplastics, a previously overlooked route for the particles to enter crops that has implications for ecology and human health

Plant Leaves Absorb Microplastics—And They End Up in Our FoodNew evidence shows plant leaves absorb airborne microplastics, a previously overlooked route for the particles to enter crops that has implications for ecology and human healthBy Willie Peijnenburg & Nature magazine Plants can absorb plastic particles directly from the air. Ruben Bonilla Gonzalo/Getty ImagesPlastic production is increasing sharply. This has raised concerns about the effects of microplastics (typically defined as plastic particles smaller than 5 millimetres in diameter) and nanoplastics (smaller plastic particles that are less than 1,000 nanometres in diameter) on human health. These concerns are partly influenced by alarming findings of the presence of microplastics in various human tissues, including the brain and placenta. Continuing research is examining pathways of human exposure to microplastics, including through food sources. Most attention is focused on soil and water as common sources of plastics that enter the food chain. However, writing in Nature, Li et al. provide strong evidence supporting the air as being a major route for plastics to enter plants.Plants can absorb plastic particles directly from the air. Particles in the air can enter leaves through various pathways, such as through structures on the leaf surface called the stomata and through the cuticle. Stomata are small openings made of cells, and the cuticle is a membrane, covered in insoluble wax, that is well suited for absorbing microplastics.Once inside the leaf (Fig. 1), microplastics move through spaces between plant cells and can also accumulate inside tiny hair-like structures, called trichomes, on the surface of leaves. Microplastics can also travel to and enter the plant’s water- and nutrient-transporting system (called the vascular bundle) and from there reach other tissues. Trichomes are ‘sinks’ for external particles and they therefore reduce the efficiency of microplastic transport from leaves to roots. Given that leaves are a key part of the food chain, microplastic particles that accumulate here can easily pass to herbivores and crop leaves, both of which can be directly consumed by humans.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

From there, microplastics can reach other tissues.Li and colleagues’ study demonstrates that the absorption and accumulation of atmospheric microplastics by plant leaves occurs widely in the environment, with the concentrations of these particles in plants being consistent with their concentrations in air at the sampling sites. The authors report that the concentrations of the microplastics polyethylene terephthalate and polystyrene were 10–100 times higher in open-air planted vegetables than in greenhouse-grown vegetables. Leaves with a longer growth duration and the outer leaves of vegetables contained higher microplastic concentrations than did younger leaves and inner leaves. Microplastic concentration in plants increased with the duration of exposure to these particles.Although the efficiency of leaf uptake of microplastics is extremely low (around 0.05%), Li and colleagues’ findings provide evidence from fieldwork of accumulation of atmospheric microplastics in leaves. The relative importance of this airborne exposure to microplastics in plants compared with that of other uptake routes is difficult to assess, because information available on microplastic uptake through soil and water is sparse. Li et al. report concentrations of polystyrene nanoplastics of about 7–10 nanograms per gram of the dry plant weight for lettuce leaves after outdoor exposure in Tianjin, China.In the case of exposure to microplastics in the water, plastic concentrations similar to those found in plants by Li and colleagues after airborne deposition could only be obtained previously by exposing lettuce roots to polystyrene nanoplastics in water, at exposure levels as high as 5 milligrams of plastic per litre of water. Another study examining plant exposure to microplastics in water reported that there was no plant uptake of these plastics from water entering a wastewater treatment site. In soil cultivation experiments reported by Li and colleagues, the root absorption of polystyrene nanoparticles that ended up in the shoot was less efficient than the absorption of airborne nanoplastics. Li and colleagues found that the level of the plastics that reached leaves from roots were well below the 7–10 nanograms per gram of dry plant weight that is associated with airborne deposition of nanoplastics. Li et al. report that levels of microplastics in air-exposed plants at highly microplastic-contaminated sites increased mostly tenfold compared with levels at non-contaminated sites.Researchers have found that microplastics in the air can enter plants, including crops, through the outer layer of cuticle and epidermal cells. They can then move through spaces between plant cells to enter tiny hair-like structures on the leaf surface called trichomes. Alternatively, after entering the leaf, microplastics can move to cells in a system called the vascular bundle that transports water and nutrients to tissues elsewhere in the plant.These findings illustrate the potential implications of airborne microplastics and nanoplastics accumulating in leaves and being transferred to herbivores and humans. This highlights a possible yet understudied pathway of plastic exposure that might have ecological and health implications. However, key gaps remain in scientists’ understanding of the various factors that influence the uptake, accumulation and biological effects of microplastics in humans. These knowledge gaps include: the composition of the average human diet and its role in determining exposure levels; the efficiency with which plastics accumulate in the gut; and the extent to which these particles reach key organs. Furthermore, there is a major lack of data on the threshold levels at which microplastics and nanoplastics might begin to exert harmful effects on human health.The combination of these uncertainties severely hinders efforts to accurately quantify the potential risks posed by airborne microplastics. Without a comprehensive and systematic approach to studying plastic fate and toxicity, our understanding remains incomplete. The current body of knowledge about the environmental and physiological effects of plastics is full of gaps, with no consistent data available on plastics of well-defined compositions, sizes, shapes or densities.A conclusion to draw from Li and co-authors’ work is that, although there is no widely supported consensus on the risks to humans from exposure to plastics, the deposition of these substances from the air into human food is an exposure pathway not to ignore. Combining these concerns with considerations of direct exposure of humans to airborne plastics might suffice to prompt the adoption of precautionary measures. Although research on the long-term health effects of plastics is still continuing, preliminary research suggests possible links to problems with breathing, inflammation and other adverse health outcomes. Given these uncertainties, integrating precautionary approaches — such as reducing plastic use and increasing public awareness — might help to lessen potential risks. Proactive measures might also encourage further scientific investigation into the extent of microplastic exposure and its health implications, ensuring better protection for individuals and for the environment.This article is reproduced with permission and was first published on April 9, 2025.
