Nearly three in four popular comfort foods have something in common, researchers find

A US study examining 300 distinct comfort foods identified chips, ice cream, pizza, chocolate, and cookies as the most frequently nominated choices among adults. Researchers found that nearly three-quarters of the foods met hyperpalatability criteria, while approximately 43% were entirely ultra-processed under a strict classification, with relatively small nutritional differences across demographic groups.

A study of 802 teens raises questions about school breakfast and blood sugar

A study of 802 U.S. adolescents found that school breakfast participation at least once weekly was associated with a 30% higher prevalence of prediabetes-range glucose markers, while school lunch participation showed no significant association. Higher intakes of vitamins E and B6 and fruit consumption among adolescents with obesity were associated with lower prediabetes prevalence, but none of the reported associations remained statistically significant after correction for multiple comparisons.

Unstable immune cells linked to severe cancer immunotherapy side effects

Scientists at the University of Pittsburgh uncovered the unstable immune cells that can cause up to 40% of immunotherapy patients to experience serious side effects and showed that diet and microbiome composition influence the side effect's severity.

Starting survivorship care earlier improves head and neck cancer survival

Beginning survivorship care for head and neck cancer patients earlier is linked to better survival and lower recurrence, according to a new University of Pittsburgh study published today in JAMA Otolaryngology–Head & Neck Surgery.

Review offers guidance for managing recurrent catheter-related bloodstream infections

Patients who depend on long-term intravenous catheters for chemotherapy, hemodialysis, intravenous nutrition and other essential therapies face an ongoing risk of catheter-related bloodstream infections, a potentially life-threatening complication that can be difficult to manage when the device remains necessary for care.

Study identifies blood proteins associated with aggressive prostate cancer risk

Proteins linked to the immune system, cell adhesion, blood vessel formation and known prostate cancer genes, were associated with the future risk of developing prostate cancer, including aggressive disease, in a new study led by researchers at Oxford Population Health.

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.

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.

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.
