Eating a plant-forward diet is good for your kidneys

Major reduced risk of chronic kidney disease with EAT–Lancet planetary diet

2026-01-26

(Press-News.org) Eating a plant-forward diet and limiting added sugars and fats as part of the EAT–Lancet planetary diet was associated with a reduced risk of chronic kidney disease (CKD), according to a large study published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.250457.

Chronic kidney disease affects about 10% of adults globally and is projected to become the fifth leading cause of death worldwide by 2040.

The study was based on data from the UK Biobank, a large-scale long-term study that included 179 508 eligible participants aged 40 to 69 from England, Scotland and Wales, and dietary information collected through a questionnaire. Over a median follow-up of 12 years, 4819 (2.7%) participants developed CKD.

“Greater adherence to the EAT–Lancet planetary health diet was significantly associated with a reduced risk of incident CKD. This protective association was particularly evident among individuals with low residential green space exposure and specific genetic variants,” writes Dr. Xianhui Qin, Nanfang Hospital, Southern Medical University, Guangzhou, China, with coauthors.

Although many plant-based diets are promoted, such as Dietary Approaches to Stop Hypertension (DASH), Alternate Mediterranean Diet (aMed), and others, the EAT–Lancet planetary health diet was developed to encompass human health as well as environmental sustainability. It emphasizes fruits, vegetables, legumes, and some meat and dairy and limited consumption of added sugars and fats.

“A key commonality among these dietary patterns is their emphasis on higher consumption of vegetables, fruits, and nuts, and reduced intake of red meat — components consistently associated with lower CKD risk in previous studies. A distinctive aspect of the EAT–Lancet diet is its specific limitation of added sugars and fats, which may further mitigate kidney risk through modulation of inflammation and oxidative stress pathways. These results underscore the potential of the EAT–Lancet diet as an effective dietary strategy for CKD prevention,” the authors write.

Elucidating liquid-liquid phase separation under non-equilibrium conditions

2026-01-26

Crystallization is a well-explored natural phenomenon where atoms or molecules arrange themselves into highly organized solid forms called as crystals. This phenomenon has been widely utilized across pharmaceutical and agrochemicals industries, as well as in food industries, to form, separate, and purify pure crystalline materials. The process is usually considered a solid-liquid phase transition, but it can also involve liquid-liquid phase separation (LLPS). In LLPS, the solution separates out into solute-rich and solute-poor liquid phases. Crucially, this secondary phenomenon can significantly ...

Fecal microbiome and bile acid profiles differ in preterm infants with parenteral nutrition-associated cholestasis

2026-01-24

Background and Aims Parenteral nutrition (PN)-associated cholestasis (PNAC) is frequently diagnosed in premature infants; however, not all PN-exposed infants develop PNAC. We propose that, in premature infants receiving PN and varying amounts of enteral feeds, differences in the gut microbiome and fecal bile acid content are associated with PNAC development. This study aimed to examine the fecal microbiome and bile acid content of premature infants on PN to determine if there is a relationship with the development ...

The Institute of Science and Technology Austria (ISTA) receives €5 million donation for AI research

2026-01-24

The Institute of Science and Technology Austria (ISTA) has received a donation of 5 million euros from Canadian philanthropist and entrepreneur Garrett Camp to help advance AI as a trustworthy, human-centered technology that benefits society. ISTA’s commitment to responsible AI, coupled with its focus on frontier research and interdisciplinary culture, make it perfectly placed to pursue this goal. Camp – who is the creator of the not-for-profit Camp.org research organization and co-founder of the ride-hailing Uber app – visited the ISTA campus on January 13 to sign the donation agreement with President Martin Hetzer and Managing Director Georg Schneider. “With ...

Study finds link between colorblindness and death from bladder cancer

2026-01-24

Recognizing the sight of blood in urine, the most common first sign of bladder cancer, is often the impetus that leads people to a diagnosis. But for those with colorblindness, who usually have difficulty seeing red, that warning sign is more likely to go down the toilet unnoticed. Now a study by Stanford Medicine researchers and collaborators has found that missing this early sign can have serious health consequences. In an analysis of health records, they discovered that people with bladder cancer who ...

Tailored treatment approach shows promise for reducing suicide and self-harm risk in teens and young adults

2026-01-23

A new study by UCLA and Kaiser Permanente Northwest’s Center for Health Research demonstrates a health care approach matching treatment intensity to individual risk levels can significantly reduce self-harm and depression among at-risk adolescents and young adults while improving patient satisfaction with care. The randomized clinical trial, published in the Journal of the American Academy of Child & Adolescent Psychiatry, is the largest study to date evaluating a stratified stepped-care approach for reducing suicide risk in young Americans. Suicide ...

Call for papers: AI in biochar research for sustainable land ecosystems

Scientists are invited to submit their latest research to a new special issue focusing on the intersection of artificial intelligence (AI) and biochar for sustainable land management. The special issue, titled "Artificial Intelligence in Biochar Ecological Applications: Advances for Soil Carbon and Sustainability in Agricultural, Forest, and Grassland Ecosystems," will be published in the journal Biochar. Agricultural land, forests, and grasslands cover most of the Earth's terrestrial surface, playing a central ...

Methane eating microbes turn a powerful greenhouse gas into green plastics, feed, and fuel

2026-01-23

Methane eating microbes could help turn a powerful greenhouse gas into everyday products like animal feed, green plastics, and cleaner fuels, according to a new scientific review of fast moving research on these unusual bacteria. The study highlights how methane consuming communities, known as methanotrophs, are emerging as biological “gatekeepers” that can both curb climate warming emissions and convert waste gases into valuable resources. “Our work shows that methanotrophs are ...

Hidden nitrogen in China’s rice paddies could cut fertilizer use

2026-01-23

A team of scientists has shown that rice paddies in two of China’s most important grain producing regions release soil nitrogen in strikingly different ways, and that these differences can be predicted using fast, low cost laboratory tests. The findings could help farmers tailor fertilizer doses to local soils, avoiding waste while maintaining high yields. “Our work shows that farmers in different rice regions are not starting from the same nitrogen baseline in their soils, even when their yields look similar,” said lead author Siyuan Cai of the Institute of Soil Science, Chinese Academy ...

Texas A&M researchers expose hidden risks of firefighter gear in an effort to improve safety and performance

2026-01-23

When firefighters respond to an emergency, the gear they wear to protect themselves can also create challenges that could jeopardize their performance and safety. Their gear is bulky, and it may not fit perfectly. Those challenges can include restricted movement, added weight and increased heat stress that raise the risk of injury and health problems down the road. Nearly 40% of the non-fatal injuries firefighters report involve their muscles and bones, and those injuries are often linked to the physical demands of the job and limitations that could be imposed by their personal protective equipment (PPE). Dr. ...

Wood burning in homes drives dangerous air pollution in winter

2026-01-23

Throwing another log into a crackling fireplace on a cold winter’s night might seem like a cozy, harmless tradition. But Northwestern University scientists have found residential wood burning is a major — yet often overlooked — contributor to winter air pollution across the United States. Although only 2% of U.S. homes rely on wood as their primary heating source, residential wood burning accounts for more than one-fifth of Americans’ wintertime exposure to outdoor fine particulate matter (PM2.5), the new study found. These tiny airborne particles can penetrate deep into the lungs ...
