Are shared fryers really off-limits for people with celiac disease?

A study finds most French fries and tortilla chips from shared fryers contain low gluten levels, suggesting revised dietary advice for celiac disease is needed.

Beef can fit into healthy diets, but what about its environmental cost?

A narrative review published in Animal Frontiers highlights beef's contribution to high-quality protein and bioavailable micronutrients, while controlled trials generally found no adverse effects on selected cardiometabolic risk markers, although long-term disease outcomes remain uncertain. The authors argue that sustainable food policies should consider nutritional needs, environmental impacts, agricultural productivity, and rural livelihoods when evaluating beef's place in healthy diets.

Blocking specific proteins protects beta cells om excessive cellular stress

Researchers at Weill Cornell Medicine have identified a molecular pathway that contributes to the death of insulin-producing beta cells in the pancreas.

Study shows circadian rhythms vary across different cell types

Biological clocks coordinate the spatiotemporal organization of metabolism with diurnal time cues, and bulk-tissue RNA sequencing studies in mammals have revealed widespread circadian (about 24 h) gene expression in mice and non-human primates.

Pure cranberry juice may help protect teeth from decay

Boil them, mash them, simmer them in a sauce. Whether they’re sweetening a salad, garnishing a cocktail or brightening up home décor, cranberries are an iconic ingredient in holiday festivities.

Rice, fish and pickles: Is the traditional Japanese diet as healthy as we think?

A systematic review of 37 studies found that greater adherence to predefined Japanese-style dietary patterns was associated with lower all-cause and cardiovascular mortality, based on pooled evidence from three cohort studies. However, health associations varied according to dietary composition, suggesting that traditional Japanese diet scores alone may not adequately distinguish the potential benefits and risks of different food combinations.

Scientists found a link between Mediterranean diet blood markers and longer survival

Researchers found that a previously validated 67-metabolite blood signature of Mediterranean diet adherence was associated with lower long-term mortality across a Spanish trial population and three US cohorts. Participants with the highest signature scores had a 23% lower relative hazard of death than those with the lowest scores in both populations, although the findings do not establish a causal relationship.

Why the same healthy diet may not work the same way for everyone

A review published in Nutrients proposes a seven-pillar precision nutrition framework that combines biological, behavioral, and environmental information to tailor dietary interventions throughout life. The authors identify potential benefits for cardiovascular, respiratory, blood, and sleep health, while emphasizing the need for further clinical trials to establish effective, accessible, and personalized nutritional strategies.

Researchers investigate molecular mechanisms linking high-calorie diets to cognitive decline

The molecular mechanisms linking a high calorie diet to cognitive impairment remain unclear. Researchers at Institute of Science Tokyo, Japan, investigated this association in mice, finding that the diet reduced nuclear protein PQBP1 expression, disrupting the alternative splicing of genes involved in synaptic function.

Not all ultra-processed foods show the same cancer risk

Ultra-processed foods show varied associations with colorectal cancer, underscoring the need for precise research on diet quality and cancer risk factors.

Could eating whey protein before meals help reduce blood sugar spikes?

A narrative review of 57 randomized trials found that milk and dairy products have inconsistent effects on long-term blood sugar control in adults with type 2 diabetes or prediabetes. Whey protein consumed before meals more consistently reduced short-term blood sugar spikes, but further research is needed to establish whether these benefits persist over time.

Fruit and sugary drinks stood out in a three-year study of teenage mental health

A three-year study of 6,537 Australian adolescents found that higher fruit consumption was associated with a lower risk of elevated depression and anxiety symptoms, while greater sugar-sweetened beverage intake was associated with increased risk. Vegetable consumption showed no significant association with either outcome, and the observational findings cannot establish cause and effect.

Researchers use mitochondrial uncouplers to target breast cancer metastasis

Mitochondrial serine catabolic pathway (MSCP), also called serine, glycine, and one-carbon metabolism, is essential for cancer cells to produce amino acids, one-carbon units, and reducing equivalents.

Could ultraprocessed foods affect your brain before you notice?

Ultraprocessed food intake correlates with increased body fat and vascular brain injury in middle-aged adults, though cognitive performance remains unaffected.

Could this flowering plant help people lose body fat?

Lythrum salicaria extract supplementation led to body fat reduction in a clinical trial, suggesting a promising plant-based approach to weight management.

Your age may not tell the whole story about your health, but your blood could

Researchers analyzed plasma metabolites from 18,476 individuals aged 1 to 96 years and developed two metabolomic aging measures to assess biological aging, chronic disease, and mortality risk. Accelerated metabolomic aging was associated with greater risks of chronic disease and death, while a separate mortality-linked measure provided additional information about health status and disease burden beyond conventional clinical assessments.

A CDC survey finds 4 in 5 US teenagers fall short of high heart health scores

A CDC study of 5,192 US high school students found that approximately 80% had low or moderate cardiovascular health scores based on five measures assessed in a national survey. Diet, sleep, and physical activity received the least favorable scores, with differences observed across sex, grade, and racial and ethnic groups.

Study: First 90 days of antipsychotic treatment critical for metabolic changes

The first 90 days after starting antipsychotic treatment are crucial for changes in blood sugar and weight, finds a new study led by UCL researchers.

Scientists reviewed studies covering 1.17 million children and found a major research gap

Researchers identified 104 pregnancy and birth cohorts representing more than 1.17 million children across 41 countries, documenting the availability of data on early-life nutrition and neurodevelopment. Approximately 99% of participants in the income-stratified analysis came from high- or upper-middle-income countries, while differences in data collection and assessment methods complicate future international comparisons.

Losing weight is one thing. Keeping your muscle is another, experts say

The International Society of Sports Nutrition (ISSN) position stand concludes that sustained calorie restriction drives weight loss, while adequate protein intake and resistance training help preserve lean mass. Reviewing intermittent fasting, ketogenic diets, and other dietary approaches, the authors emphasize individualized nutrition plans, body composition, and sustainable weight management rather than rapid weight loss alone.
