Arizona State University researchers report that people who produce more methane in the gut tend to extract more metabolizable energy from a fiber‑rich diet, pointing to microbiome differences that could inform personalized nutrition. The work appears in The ISME Journal (2025) and was highlighted by ASU on October 24, 2025.
Vitamin D supplements slow telomere shortening in new study
A recent study suggests that daily vitamin D supplements could help preserve telomeres, the protective caps on chromosomes linked to aging. Researchers at Augusta University found that 2,000 IU doses maintained telomere length in older adults over four years. While promising, experts caution that optimal dosing remains unclear and lifestyle factors are essential for health.
Neurons use fat—not just sugar—for energy, study ties pathway to rare brain disorder
Heather Vogel Fact checked
Researchers in Australia and Finland report that neurons can fuel themselves with fat as well as sugar, challenging long‑held assumptions about brain energy. The discovery, published in Nature Metabolism, links a lipid‑processing enzyme to a rare hereditary spastic paraplegia and suggests that targeted fatty acid supplements may restore cellular energy in laboratory models.
Lancet review questions gluten as main driver of most ‘gluten sensitivity’ symptoms
Heather Vogel Fact checked
A University of Melbourne–led review published in The Lancet on October 22, 2025, argues that many symptoms attributed to non‑coeliac gluten sensitivity are more often linked to FODMAPs, other wheat components, and gut–brain interactions than to gluten itself. The authors call for better diagnostics, individualized care, and a shift away from unnecessary gluten avoidance.
Study debunks link between calcium supplements and dementia
New research from Australian universities shows that calcium supplements do not increase dementia risk in older women. The findings, based on a long-term study of over 1,400 participants, counter earlier concerns about cognitive effects. Experts say the results reassure users taking calcium for osteoporosis prevention.

Study links higher fruit and vegetable intake to better same‑day sleep

Researchers at the University of Chicago Medicine and Columbia University report that eating more fruits and vegetables during the day was associated with better sleep that night in healthy young adults. Meeting a five‑cup daily intake used to represent CDC recommendations was linked to an estimated 16% improvement in sleep quality, based on objective measures. The authors describe this as the first study to show a same‑day association between diet and objectively measured sleep.
Randomized trial finds certain processed hard fats did not worsen short-term heart risk markers
Heather Vogel Fact checked
A small randomized crossover study found no meaningful differences in cholesterol or other short‑term cardiometabolic markers when healthy adults consumed either palmitic‑rich or stearic‑rich interesterified fats for six weeks apiece.
New iron supplement treats anemia without gut irritation
Researchers have developed a three-in-one iron supplement combining iron, probiotics, and prebiotics to treat iron-deficiency anemia while preserving gut health. In studies on mice, the formula restored hemoglobin levels and balanced gut bacteria without causing inflammation. This innovation could improve anemia treatment by reducing common side effects of traditional supplements.
Study finds diet sodas raise liver disease risk as much as sugary ones
A large UK study has shown that both sugar-sweetened and low- or no-sugar soft drinks increase the risk of metabolic dysfunction-associated steatotic liver disease (MASLD). Consuming more than one can daily was linked to up to 60% higher odds of developing the condition. The findings, presented at UEG Week 2025, challenge the view of diet drinks as a healthier alternative.
Bananas may reduce flavanol absorption in smoothies, UC Davis-linked study finds
Heather Vogel Fact checked
A small UC Davis–affiliated trial reports that a banana-based smoothie markedly lowered the body’s uptake of flavan-3-ols—about 84% less at peak plasma levels than after a control capsule—an effect the researchers link to the fruit’s polyphenol oxidase enzyme.
