Across Farm Country, Fertilizer Pollution Impacts Not Just Health, but Water Costs, Too

News Feed
Wednesday, May 1, 2024

When Jeff Broberg and his wife, Erica, moved to their 170-acre bean and grain farm in Winona, Minnesota in 1986, their well water measured at 8.6 ppm for nitrates. These nitrogen-based compounds, common in agricultural runoff, are linked to multiple cancers and health issues for those exposed. Each year, the measurement in their water kept creeping up. In the late 1990s, Broberg decided it was time to source from elsewhere. He began hauling eight one-gallon jugs and two five-gallon jugs from his friend Mike’s house. That was his drinking water for the week. Six years ago, Broberg said, he was “getting too old to haul that water in the middle of the winter.” So, he installed his own reverse-osmosis water filtration system. The measurement of nitrates in his well has now reached up to 22 ppm. Post-filtration, the levels are almost nonexistent. Broberg, a retired geologist, has committed what he calls his “encore career” to advocating for clean water in Minnesota. He only leases out around 40 percent of his tillable land and has retired much of the rest due to groundwater pollution concerns. Almost one year ago, a group he co-founded, the Minnesota Well Owners Organization, joined other groups to petition the U.S. Environmental Protection Agency (EPA) to address groundwater contamination in southeast Minnesota. The EPA agreed, stating that “further action is needed to protect public health” and requested that the state create a plan for testing, education and supplying alternative drinking water to those most affected. Advocates in Wisconsin filed a petition, too. Last month, 13 separate groups in Iowa did the same. This advocacy comes in light of increased regional attention on nitrate pollution and its health effects. In Nebraska, researchers have connected high birth defect rates with exposure to water contaminated with nitrates. In Wisconsin, experts warn that exposure to nitrates can increase the risk of colon cancer. Access to clean water, as defined by the United Nations, is a human right. And yet many currently don’t have that right, even in a country where potable water is taken for granted. What’s more, the cost of clean water falls more heavily on less populated areas, where fewer residents shoulder the bill. A report by the Union of Concerned Scientists concluded that the cost for rural Iowa residents—who often live in areas with smaller, more expensive water systems—could be as much as $4,960 more per person per year to filter out nitrates from their water than their counterparts in cities like Des Moines. Nitrates are affecting water utilities from California to D.C., and the reason comes down to one major source: Agricultural runoff. Where The Trouble Begins: ‘A Leaky System’ The root of water-quality issues in the Midwest starts with its cropland drainage system, a network of underground, cylindrical tiles that drain excess water and nutrients from the land and funnel it downstream. Those tiles, which were first installed in the mid-1800s and have now largely been replaced with plastic pipes, ultimately allowed farmers to grow crops on land that was once too wet to farm. Lee Tesdell is the fifth generation to own his family’s 80-acre farm in Polk County, Iowa. Tesdell explained that when his European ancestors settled in the Midwest, they plowed the prairie and switched from deeply rooted perennial plants to shallow-rooted annual crops like wheat, oats, and corn instead. “Then we had more exposed soil and less water infiltration because the roots weren’t as deep,” he said. “The annual crops and drainage tile started to create this leaky system.” This “leaky system” refers to what is not absorbed by the crops on the field, most dangerously, in this case, fertilizer. “It’s a leaky system because it’s not in sync,” said Iowa water quality expert Chris Jones, author of The Swine Republic book (and blog).  “And farmers know they’re going to lose some fertilizer. As a consequence, they apply extra as insurance.” Fertilizer as Poison The U.S. is the top corn-producing country in the world, with states like Iowa, Illinois, Nebraska, and Minnesota supplying 32 percent of corn globally. Corn produces lower yields if it is nitrogen deficient, so farmers apply nitrogen-heavy fertilizer to the crop. In fact, they must use fertilizer in order to qualify for crop insurance. The ammonia in the fertilizer oxidizes existing nitrogen in the soil, turning it into highly water-soluble nitrates that aren’t fully absorbed by the corn. Those nitrates leak into aquifers. In 1960, farmers used approximately 3 million tons of nitrogen fertilizer a year. In 2021, that number was closer to 19 million. Farmers can use a nitrogen calculator to determine how much nitrogen they need—but nearly 70 percent of farmers use more than the recommended amount. “Other people also have an American dream, and they want to be able to turn on their faucet and have clean water, or know that if they put their baby in a bath, they’re not going to end up in the hospital with major organs shutting down because they have been poisoned.” As Jones explains in his blog, even with “insurance” fertilizer use, yields can often turn out the same: “What happened to that extra 56 pounds of nitrogen that you bought? Well, some might’ve ended up sequestered in the soil, but a lot of it ran off into lakes and streams or leached down into the aquifer (hmm, do you reckon that’s why the neighbor’s well is contaminated?), and some off-gassed to the atmosphere as nitrous oxide, a substance that has 300 times more warming potential than carbon dioxide.” Commercial fertilizer is just one contributor to high nitrate levels in groundwater. The other main factor, manure, is also increasing as CAFOs become more prevalent. Nancy Utesch and her husband, Lynn, live on 150 acres of land in Kewaunee County, Wisconsin, where they rotationally graze beef cattle. In 2004, a family nearby became very ill from E. coli poisoning in their water. “I was really upset that this had happened in our county,” she said. “A lot of the support was for the polluting farmer, and you know, farming is right there with the American flag and grandma’s apple pie.” Utesch worries that the current system of industrialized agriculture has created a world where people living closest to the polluters do not have access to clean water themselves, and are afraid to speak out against the actions of their neighbors. “Other people also have an American dream, and they want to be able to turn on their faucet and have clean water, or know that if they put their baby in a bath, that they’re not going to end up in the hospital with major organs shutting down because they have been poisoned,” she said. “If they clean a scrape because their grandchild fell down in the driveway, they could be hurting them if they use the water from the tap.” The Plight of the Small Town In June 2022, fertilizer runoff pushed Des Moines Water Works, the municipal agency charged with overseeing drinking water, to restart operations of their nitrate removal system—one of the largest in the world—at a cost of up to $16,000 per day. Des Moines finances its removal system from its roughly 600,000 ratepayers. “Financially, Des Moines can spread out needed treatment over many thousands of customers, whereas a small town can’t do that,” Jones said. “If you have a small town of 1,000 people, your well gets contaminated, and you need a $2 million treatment plan to clean up the water, that’s a burden.” “Financially, Des Moines can spread out needed treatment over many thousands of customers, whereas a small town can’t do that.” While cities like Des Moines are willing to pay the cost to remove nitrates, other small communities will have a tougher time doing so. And once their aquifer is contaminated, “it doesn’t go away for a long time, in some cases, thousands of years,” Jones said. Utica, Minnesota, which has fewer than 300 residents, has two deep wells, both measuring at unsafe levels for nitrates. “[Residents are] scared to death,” Broberg, who lives in a neighboring town, said. “The city has investigated water treatment expenses at around $3 million for reverse osmosis, and they only last 10 years. A town of 85 households can’t amortize that debt by themselves.” The town has applied for a grant from the state and is waiting to hear back. Another nearby town, Lewiston, dug a new, deeper well to solve their nitrate problem. “They went down there, and the water was contaminated with radium. It’s radioactive,” Broberg said. “So they kept their nitrate-contaminated well and their radium-contaminated well and blended the water so that it doesn’t exceed the health risk limit for either nitrates or radium.” However, as Chris Rogers reported in the Winona Post, that plan didn’t quite work. Thus, Lewiston dug another well at a cost of $904,580, and is now sourcing all of their water from that new well. That well is now testing trace amounts of nitrates and has less radium than before. Many rural residents also rely on private, personal well systems, which aren’t regulated for contaminants, to source their water. Forty million people rely on well water nationwide. “Public water systems have these maximum contaminant levels that are set by the EPA. There are rules and regulations that they have to follow, but private wells aren’t covered by the Safe Drinking Water Act,” said Stacy Woods, research director of the food and environment program at the Union of Concerned Scientists. “It’s really on individual well owners to decide whether to test their wells and what contaminants to test their wells for, and these tests can be really expensive.” Broberg and his group are working to extend the protection of the Safe Drinking Water Act to well water. In southeast Minnesota, the EPA agreed to the plan, though the path forward is still uncertain as funding packages move through the legislature. “I’ve spoken with people who simply don’t want to test their well water because they can’t afford to do much about it if they find out that their nitrate levels are unsafe.” Without these protections in place, or intervention at the pollution source, rural residents often find the responsibility of clean water falling on them. “I’ve spoken with people who simply don’t want to test their well water because they can’t afford to do much about it if they find out that their nitrate levels are unsafe,” Food and Water Watch Legal Director Tarah Heinzen said. “They are basically powerless to protect their drinking water resources from sources of pollution that aren’t being adequately regulated by the state.” The solution, according to Woods, “is to protect the drinking water sources from that pollution in the first place.” Conservation on the Farm One way to do this is by using less fertilizer on the field. Another is to introduce on-the-field and edge-of-field conservation practices, like Tesdell is doing on his Iowa family farm. Tesdell’s farm is not the typical Iowa farm, which averages 359 acres. Tesdell’s is 80. He does, however, rent 50 acres to a neighbor who grows corn and soybeans, like most Iowa farmers. Where Tesdell’s farm differs is how he deals with excess nitrate. In 2012, Tesdell, who has always been drawn to conservation, became interested in adding cover cropping to his fields. Through his research, he came across other conservation practices such as wood chip bioreactors. He installed his first bioreactor that same year. “There’s a chemical and biological reaction between the wood chips and the nitrate in the tile water,” Tesdell said. “Much of the nitrate then is turned into nitrogen gas, which is a harmless gas. We don’t take out 100 percent of the nitrate, but we take out a good percentage.” According to Iowa State University, a typical bioreactor costs around $10,000 to design and install. Tesdell paid for his bioreactor partly out of pocket, but also acquired funding from the Iowa Soybean Association. For his saturated buffer, an edge-of-field practice that redirects excess nitrates through vegetation, Tesdell received funding from the USDA’s Environmental Quality Incentives Program (EQIP). To install the saturated buffer, Tesdell needed his neighbor to agree. “We put that one on a tile that actually comes from my neighbor’s farm. Because the creek is going through my farm, it’s a more direct route to come off a hill [on] his farm,” he said. “Neighbors need to work together.” Roughly 80 percent of the farmland in Iowa is owned by offsite landlords, who rent it out to farmers. Tesdell cites this as  a roadblock to conservation practices. “If the landowner doesn’t care, why would an operator care? They want to pull in with their 24-row planter, plant their corn, come in with the 12-row corn head in October and harvest, then truck it off to the ethanol plant,” he said. “I don’t blame them.” Iowa currently has a “Nutrient Reduction Strategy” plan, which outlines voluntary efforts farmers can take to reduce their pollution. There is no active legislation that limits how much fertilizer farmers use on their cropland. Heinzen, of Food and Water Watch, explained that agricultural pollution is largely unregulated, with the exception of concentrated animals feeding operations (CAFOs).  “In fact, even most CAFOs are completely unregulated, because EPA has completely failed to implement Congress’s intent to regulate this industry, which we’re suing them over,” she said, referring to a new brief filed by multiple advocacy groups in February aimed at upgrading CAFO pollution regulation. Even Des Moines Waterworks, with its state-of-the-art nitrate removal facility, is calling for change. “We cannot keep treating water quality only at the receiving end,” spokesperson Melissa Walker said. “There needs to be a plan for every acre of farmland in Iowa and how its nutrients will be managed, as well as every animal and its manure.” “You’re either going to have to change your practices, change your farming, or you’re going to have the accept the risk of preventable disease.” Some communities have sued for damages related to nitrate-contaminated groundwater. In Millsboro, Delaware, residents received a payout but still have contaminated water. In Boardman, Oregon, five residents are suing the Port of Morrow and multiple farms and CAFOs due to their well-water testing “at more than four times the safe limit established by the U.S. EPA,” Alex Baumhardt reported in the Oregon Capital Chronicle. A few weeks ago, 1,500 tons of liquid nitrogen were spilled into an Iowa river. No living fish were found nearby. Today, polluted water flows downstream into the Gulf of Mexico, where it causes “dead zones” stripped of marine life. “You’re either going to have to change your practices, change your farming, or you’re going to have the accept the risk of preventable disease,” Broberg said. “And you need to put that equation in your family budget. If you’re going to get bladder cancer, diabetes, birth defects, juvenile cancers—what are those going to cost?” When asked why protecting water is so important, Tesdell paused and looked away. His voice cracked with emotion. “It’s for the grandkids.” The post Across Farm Country, Fertilizer Pollution Impacts Not Just Health, but Water Costs, Too appeared first on Civil Eats.

Turns Out, There Are 5 Sleep Styles — And Each Affects Your Brain Differently

By I. Edwards HealthDay ReporterTHURSDAY, Oct. 9, 2025 (HealthDay News) — A new study suggests there’s more to sleep than how long you snooze each...

THURSDAY, Oct. 9, 2025 (HealthDay News) — A new study suggests there’s more to sleep than how long you snooze each night. Your overall sleep pattern could shape your mood, brain function and even long-term health.Researchers from Concordia University in Montreal identified five distinct sleep profiles that may help explain why some people feel well-rested while others struggle with fatigue, poor focus or emotional ups and downs.The findings, published Oct. 7 in PLOS Biology, show that these “sleep-biopsychosocial profiles” reflect a mix of biological, mental and environmental factors — from stress and emotions to bedroom comfort — that all affect how well you sleep.“People should treat their sleep seriously,” study co-author Valeria Kebets, a manager at Concordia’s Applied AI Institute, told NBC News. “It affects everything in their daily functioning.”The researchers identified five sleep profiles:1. Poor sleep and mental healthPeople in this group reported the worst sleep quality and higher levels of stress, fear and anger. They also had a greater risk of anxiety and depression.These individuals had poor mental health or attention issues but said their sleep felt fine, suggesting “sleep misperception,” or being unaware of underlying sleep problems, researchers said.3. Sleep aids and sociabilityThis group used sleep aids, but also reported strong social support and fewer feelings of rejection. However, they showed lower emotional awareness and weaker memory.4. Sleep duration and cognitionPeople sleeping fewer than six to seven hours a night scored lower on tests measuring problem-solving and emotional processing. They also showed higher aggression and irritability.5. Sleep disturbances and mental healthThose with issues like frequent waking, pain or temperature imbalance had higher rates of anxiety, substance use and poor cognitive performance.The study analyzed data from 770 healthy adults aged 22 to 36, using MRI scans and questionnaires about sleep, lifestyle and mood.Experts say the profiles could help doctors tailor sleep treatments in the future.“We really need to consider multiple sleep profiles in our research and clinic — the value of a multidimensional approach to data,” Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University, who was not involved in the study, told NBC News.Sleep experts also say the research reinforces the importance of good rest for both mental and physical health.“Sleep is a more complex issue than just how much time you spend in bed,” Dr. Rafael Pelayo, a sleep medicine specialist at Stanford University, said in the NBC News report. “If I can improve your sleep, it has downwind effects on your overall health — not just your mental health, but your physical health.”SOURCE: NBC News, Oct. 8, 2025Copyright © 2025 HealthDay.

Wildfire Smoke Might Damage Male Fertility

By Dennis Thompson HealthDay ReporterTHURSDAY, Oct. 9, 2025 (HealthDay News) — Wildfire smoke could be damaging men’s fertility, according to a new study.Key measures of sperm quality appeared to drop among dozens of men participating in fertility treatments, researchers recently reported in the journal Fertility and Sterility.“These results reinforce growing evidence that environmental exposures — specifically wildfire smoke — can affect reproductive health,” said senior researcher Dr. Tristan Nicholson, an assistant professor of urology in the University of Washington School of Medicine in Seattle.“As we see more frequent and intense wildfire events, understanding how smoke exposure impacts reproductive health is critical,” she added in a news release.For the study, researchers analyzed semen samples from 84 men taken as part of intrauterine insemination procedures in the Seattle area between 2018 and 2022.Major wildfire smoke events hit Seattle in 2018, 2020 and 2022, researchers noted. The team compared the men’s sperm quality during and between these events.“This study takes advantage of our institution’s location in the Puget Sound region, where wildfire smoke events create distinct pre- and post-exposure periods in a natural experiment to examine how a sudden, temporary decline in air quality influences semen parameters,” researchers wrote.Results showed consistent declines in sperm concentration, total sperm count and sperm movement during wildfire smoke exposures.Wildfire smoke contains particle pollution that can invade a person’s organs through their lungs and bloodstream, researchers said.This exposure has previously been linked to lung cancer, respiratory disease, heart attack, stroke and mental impairment, but its effect on male fertility has not been well-studied, researchers said.Overall, the pregnancy rate among the men’s partners was 11%, and the live birth rate 9% — both at the low end of the average range, researchers noted.However, the team added that the study was not designed to fully evaluate the direct impact of wildfire smoke on reproductive outcomes.Researchers next plan to see what happens after wildfire smoke has dented a man’s fertility.“We are very interested in how and when sperm counts recover after wildfire smoke exposure,” Nicholson said. “Currently we are conducting a prospective pilot study of men in the Seattle area to evaluate how wildfire smoke affects sperm quality.”SOURCE: University of Washington, news release, Oct. 1, 2025Copyright © 2025 HealthDay.

AirPods Pro 3 review: better battery, better noise cancelling, better earbuds

Top Apple buds get upgraded sound, improved fit, live translation and built-in heart rate sensors, but are still unrepairableApple’s extremely popular AirPods Pro Bluetooth earbuds are back for their third generation with a better fit, longer battery life, built-in heart rate sensors and more effective noise cancelling, and look set to be just as ubiquitous as their predecessors.It has been three years since the last model, but the earbuds still come only in white and you really have to squint at the details to spot the difference from the previous two generations.

Apple’s extremely popular AirPods Pro Bluetooth earbuds are back for their third generation with a better fit, longer battery life, built-in heart rate sensors and more effective noise cancelling, and look set to be just as ubiquitous as their predecessors.The Guardian’s journalism is independent. We will earn a commission if you buy something through an affiliate link. Learn more.It has been three years since the last model, but the earbuds still come only in white and you really have to squint at the details to spot the difference from the previous two generations.The AirPods Pro 3 cost £219 (€249/$249/A$429), making them £30 cheaper in the UK than when their predecessors launched, and sit above the AirPods 4, which cost £169 with noise cancelling for those who don’t like silicone earbud tips.The shape of the earbuds has been tweaked, changing slightly the way you put them in and making them more comfortable than their predecessors for extended listening sessions of three hours or more. Five sizes of tips are included in the box, but if you didn’t get on with silicone earbuds before these won’t make a difference.The stalks are the same length as before, but the shape of the earbud has been changed to better align the tip with your ear canal. Photograph: Samuel Gibbs/The GuardianMost of the features are fairly standard for modern earbuds. Squeeze the stalks for playback controls, swipe for volume or take them out to pause the music. They support the same new features rolled out to Apple’s older earbuds, including the ability to use them as a shutter remote for the camera app and for live translation with the Translate app on the iPhone. The latter is limited to English, French, German, Portuguese and Spanish for now and isn’t available in the EU, but it works surprisingly well for casual conversations.The biggest problem is that the other person will have to rely on reading or hearing your translated speech from your iPhone. I can see it being most useful with announcements or audio guides – the kind you get on transport or in museums where you need only to translate language one way.The most interesting added hardware feature is heart rate monitoring via sensors on the side of the earbuds, similar to Apple’s Powerbeats Pro 2 fitness buds. They can be used with more than 50 workouts started in the Fitness app or a handful of third-party apps on the iPhone and proved to be roughly in line with readings from a Garmin Forerunner 970 or an Apple Watch during walks and runs. The earbuds are water-resistant to IP57 standards, which makes them much more robust against rain and sweat than before.The battery life has been increased by a third to at least eight hours of playback with noise cancelling for each charge, which is very competitive with some of the best rivals and long enough for most listening sessions.The compact flip-top case provides two full charges for a total playback time of 24 hours – six hours short of the previous generation, but five minutes in the case is enough for an hour of listening time. Photograph: Samuel Gibbs/The GuardianSpecifications Connectivity: Bluetooth 5.3, SBC, AAC, H2 chip, UWB Battery life: eight hours ANC playback (24 hours with case) Water resistance: IP57 (buds and case) Earbud dimensions: 30.9 x 19.2 x 27.0mm Earbud weight: 5.6g each Charging case dimensions: 47.2 x 62.2 x 21.8mm Charging case weight: 44g Case charging: USB-C, Qi wireless/MagSafe, Apple Watch Bigger sound and impressive noise cancellingThe silicone earbuds are infused with foam in the tips that expands slightly for a better seal for music and noise cancelling. Photograph: Samuel Gibbs/The GuardianThe sound of the third-generation AirPods Pro takes a great listen and makes it bigger. They have a wider soundscape that makes big tracks sound more expansive, while still maintaining strong but nicely controlled bass. They are detailed, well-balanced and do justice to different genres of music, with plenty of power and punch where needed. As with Apple’s other headphones, they sometimes sound a little too clinical, lacking a bit of warmth or rawness in some tracks, and they can’t quite hit the very deepest of notes for skull-rattling bass. However, few earbuds sound better at this price and size.Apple’s implementation of spatial audio for surround sound for movies remains best in class, adding to the immersion with compatible devices and services, even if spatial audio music remains a mixed bag.The AirPods Pro are the best combination of earbuds and compact case that you can easily fit in a pocket. Photograph: Samuel Gibbs/The GuardianThe improved noise cancelling is the best upgrade. Apple says it is twice as effective as the already good AirPods Pro 2, which sounds about right. In side-by-side comparisons, the AirPods Pro 3 handle street noise, including cars, horns and engines, almost as well as the class-leading Sony WH-1000XM6, which is thoroughly impressive given they are large over-ear headphones, not little earbuds.They also do a great job of dampening the troublesome higher tones such as keyboard clicks and speech, making the commute and office work more bearable.Apple’s class-leading transparency mode is just as good on the new earbuds, sounding natural as if you weren’t actually wearing the earbuds. It makes using them as hearing aids or out on the street with some dampening of sudden loud sounds very good indeed.Call quality is first-rate, and my voice sounded clear and natural in quiet or noisy environments with only a hint of road noise from some loud streets audible on the call.SustainabilityThe case charges via USB-C, MagSafe, Qi or Apple Watch charger, and has a new feature to limit charging of the earbuds to prolong their battery health. Photograph: Samuel Gibbs/The GuardianApple does not provide an expected lifespan for the batteries. Those in similar devices typically maintain at least 80% of their original capacity for 500 full charge cycles. The earbuds are not repairable, but Apple offers a battery service for £49 per earbud or case and offers replacements for those lost or damaged costing from £79 an item. The repair specialists iFixit rated the earbuds zero out of 10 for repairability.The AirPods and case contain 40% recycled material by weight including aluminium, cobalt, copper, gold, lithium, plastic, rare earth elements and tin. Apple offers trade-in and free recycling schemes and breaks down the environmental impact of the earbuds in its report.PriceThe AirPods Pro 3 cost £219 (€249/$249/A$429).For comparison, the AirPods 4 start at £119, the Beats Powerbeats Pro 2 cost £250, the Sennheiser Momentum TW4 cost £199, the Google Pixel Buds Pro 2 cost £219, the Sony WF-1000XM5 cost £219 and the Bose QuietComfort Ultra earbuds cost £300.VerdictThe AirPods Pro 3 take what was great about the ubiquitous second-generation models and improves almost everything.Longer battery life and a better, more comfortable fit for extended listening sessions are very welcome, as is the bigger, wider sound. Proper water resistance and built-in heart rate monitoring makes them useful for workouts, particularly those such as powerlifting that make wearing a watch difficult. The live translation feature worked better than expected, but has limitations that make it less useful for real-life conversations.The best bit is very effective noise cancelling that rivals some of the greatest over-ear headphones, but in a tiny set of earbuds that are much easier to carry around.Audiophiles will find they sound a little too clinical. While they work with any Bluetooth device, including Android phones, PCs and games consoles, they require an iPhone, iPad or Mac for full functionality. But the biggest letdown remains repairability, which remains a problem for most true wireless earbuds and loses them a star. Pros: very effective noise cancelling, great sound, best-in-class transparency, water resistance, built-in HR monitoring, great controls, advanced features with Apple devices including spatial audio, very comfortable, excellent case, top class call quality. Cons: extremely difficult to repair, expensive, no hi-res audio support, lack features when connected to Android/Windows, look the same as predecessors, only available in white. The AirPods Pro 3 are some of the very best earbuds you can buy, particularly if you use an iPhone. Photograph: Samuel Gibbs/The Guardian

If You Want to Stay Healthy and Care About Humanity, Here’s What to Eat

This story was originally published by Guardian and is reproduced here as part of the Climate Desk collaboration. Adoption of a plant-rich “planetary health diet” could prevent 40,000 early deaths a day across the world, according to a landmark report. The diet—which allows moderate meat consumption—and related measures would also slash the food-related emissions driving global heating by half by 2050. Today, a third of greenhouse gas emissions come from the global food system and taming the climate crisis is impossible without changing how the world eats, the researchers said. Food production is also the biggest cause of the destruction of wildlife and forests and the pollution of water. The planetary health diet (PHD) sets out how the world can simultaneously improve the health of people and the planet, and provide enough food for an expected global population of 9.6 billion people by 2050. “This is not a deprivation diet…” It “could be delicious, aspirational and healthy.” The diet is flexible, allowing it to be adapted to local tastes, and can include some animal products or be vegetarian or vegan. However, all versions advise eating more vegetables, fruits, nuts, legumes and whole grains than most people in the world currently eat. In many places, today’s diets are unhealthy and unsustainable due to too much meat, milk and cheese, animal fats and sugar. People in the US and Canada eat more than seven times the PHD’s recommended amount of red meat, while it is five times more in Europe and Latin America, and four times more in China. However, in some regions where people’s diets are heavily reliant on starchy foods, such as sub-Saharan Africa, a small increase in chicken, dairy and eggs would be beneficial to health, the report found. North American adult diets in 2020 versus planetary health recommendation, daily per capita intake in grammesGuardian Severe inequalities in the food system must also be ended to achieve healthy and sustainable diets, the researchers said. The wealthiest 30 percent of the world’s population generates more than 70 percent of food-related environmental damage, it found. Furthermore, 2.8 billion people cannot afford a healthy diet and 1 billion are undernourished, despite enough food being produced globally. The food system is also failing the 1 billion people living with obesity, the report said. The report recommends shifting taxes to make unhealthy food more costly and healthy food cheaper, regulating the advertising of unhealthy food and using warning labels, and the shifting of today’s massive agricultural subsidies to healthier and more sustainable foods. “What we put on our plates can save millions of lives, cut billions of tonnes of emissions, halt the loss of biodiversity, and create a fairer food system,” said Prof Johan Rockström, who co-chaired the EAT-Lancet Commission that produced the report. “The evidence is undeniable: transforming food systems is not only possible, it’s essential to securing a safe, just, and sustainable future for all.” “This is not a deprivation diet,” said Prof Walter Willett of the Harvard TH Chan school of public health, and another commission co-chair. “This is something that could be delicious, aspirational and healthy. It also allows for cultural diversity and individual preferences, providing flexibility.” “Our recommendations are grounded in scientific evidence and real-world experience.” The report, published in the Lancet, was produced by 70 leading experts from 35 countries and six continents. It builds on the 2019 report that introduced the PHD, but includes new evidence of the health benefits of the diet. “We have been able to look at this diet in relation to health outcomes such as total mortality, diabetes, respiratory diseases, heart disease, stroke, etc and we found very strong inverse relationships” said Willett. The diet was also linked to reduced cancer and neurodegenerative diseases. Overall, the researchers estimated global adoption of the PHD could prevent 15m early deaths a year in adults. The estimate did not include the impact of the diet reducing obesity, meaning it is probably an underestimate. The PHD recommends plant-rich, flexible diets, including: Fruits and vegetables—at least five portions a day Whole grains—three to four portions a day Nuts—one portion per day Legumes (beans, peas, lentils)—one portion per day Dairy—one serving of milk, yoghurt or cheese portions a day Eggs —three to four a week Chicken—two portions a week Fish—two portions a week Red meat—one portion a week Marco Springmann from UCL in the UK and an author of the report said the differences between the PHD and current diets vary: “What needs to be reduced differs a lot. In low income countries, it’s the starchy foods and grains, whereas in high income countries it is animal-sourced foods, sugar, saturated fats, and dairy. It’s insane how much dairy is consumed in Europe and North America.” The data underlying the report is available online and can be used to tailor different planetary health diets for the tastes of people in specific countries and of different ages. The website also shows how much the diets reduce deaths, improve nutrition, and cut environmental impacts. “Hopefully this will lead to more science-based policymaking,” said Springmann. The PHD is better than current average diets for many nutrients, including fatty acids, fibre, folate, magnesium and zinc. Adequate iron and vitamin B12 could be provided by green leafy vegetables, fermented soy foods and algae, the researchers said. Moving diets towards the PHD could be achieved by helping consumers make better everyday choices, said Line Gordon, director of the Stockholm Resilience Centre, for example by shifting taxes to make healthy foods cheaper, and putting warning labels on unhealthy foods. “But it is not just about getting prices lower, it’s also about bringing purchasing power up so that people can afford a healthier diet” she said. “Our recommendations are grounded in scientific evidence and real-world experience,” Gordon said. “Changes are already under way, from school meal programmes to regenerative agriculture and food waste reduction initiatives.” England banned price promotions on unhealthy foods on Wednesday and will ban advertising such foods online. The report estimates that food-related ill health and environmental damage costs society about $15 trillion a year. It said investments to transform the food system would cost $200 billion to $500 billion a year, but save $5 trillion. Alongside a shift in diets, the report calls for other changes to the food system, including cutting the loss and waste of food, greener farming practices, and decent working conditions, as a third of food workers earn below living wages. The launch of the PHD in 2019 led to attacks from meat industry interests. Rockström said: “The [new report] is a landmark achievement. It is a state-of-the-art scientific assessment that quantifies healthy diets for all human beings in the world and the environmental boundaries all food systems need to meet to stay safe. So we have a really rigorous foundation for our [results]. We are ready to meet that assault.”

Seasonal Allergies Might Increase Suicide Rate, Study Says

By Dennis Thompson HealthDay ReporterMONDAY, Oct. 6, 2025 (HealthDay News) — Seasonal allergies are considered an annoyance to most, and maddening to some.Few think of seasonal sniffles and sneezes as potentially fatal — but we might be overlooking the danger they pose, a new study warns.High pollen counts are linked to a significant increase in suicide risk, according to findings published in the December issue of the Journal of Health Economics as the U.S. enters fall allergy season.Further, suicide risk increases as airborne levels of pollen rise, researchers found.The physical misery caused by seasonal allergies likely contributes to this increase, by wrecking people’s sleep and increasing mental distress, researchers speculated."During our study period, there were nearly 500,000 suicides in the U.S.," said lead researcher Joelle Abramowitz, an associate research scientist at the University of Michigan’s Institute for Social Research."Based on our incremental data, we estimate that pollen may have been a contributing factor in up to 12,000 of those deaths over the period, or roughly 900 to 1,200 deaths per year,” she said in a news release.For the study, researchers compared suicides reported between 2006 and 2018 with daily pollen counts from 186 counties in 34 metropolitan areas across the United States.Results showed an association between suicide and pollen counts that increases in strength, after the research team divided pollen levels into four tiers.Suicide risk jumped 7.4% at the worst pollen counts; 5.5% higher at the third-highest level; and 4.5% at the second level, all compared to the lowest level of airborne pollen.People with known mental health problems were more vulnerable, experiencing a nearly 9% increase in their risk of suicide on days with the highest pollen counts, results showed.“A small shock could have a big effect if you're already in a vulnerable state," Abramowitz said.The results indicate that seasonal allergies should be taken more seriously, and not seen as a mere nuisance, researchers said.More accurate pollen forecasting and better public communication on the mental health impact of seasonal allergies could save lives, by providing people the opportunity to protect themselves, researchers said.This will become even more important as climate change progresses, extending and intensifying pollen seasons, researchers said."We should be more conscious of our responsiveness to small environmental changes, such as pollen, and our mental health in general," Abramowitz said."Given our findings, I believe medical providers should be aware of a patient's allergy history, as other research has also established a connection between allergies and a higher risk for suicide,” she added. “I hope this research can lead to more tailored care and, ultimately, save lives."SOURCE: University of Michigan, news release, Sept. 29, 2025Copyright © 2025 HealthDay.
