Brief dietary changes may prime the immune system for inflammation

Scientists have long known that diet shapes the immune system. Now, a UC San Francisco team has found that even a brief dietary change can substantially change how the body responds to skin irritation, at least in mice.

New framework guides safer obesity drug prescribing in older adults

Today, the American Geriatrics Society (AGS) released a new framework to assist clinicians to safely prescribe obesity medications in older adults.

Worried nuts will cause weight gain? A large review puts that concern in perspective

A systematic review and meta-analysis of randomized trials found that eating nuts modestly reduced body fat and improved cholesterol levels without significantly changing body weight. The review did not establish that nuts rich in monounsaturated fats offered greater body-composition benefits than those rich in polyunsaturated fats.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

Circadian desynchronization: The hidden cost of daylight saving time transitions

Turning the clocks back an hour each fall can feel like a gift: an extra hour of sleep. But the tradeoff is less daylight in the evening, and the annual switch continues to earn mixed reviews.

Limited app use adds a twist to a nurse-led dementia risk trial

A cluster-randomized trial involving 403 Australian adults aged 45–65 found that a 12-month nurse-led behavioral intervention supported by a mobile app modestly improved estimated dementia risk scores compared with brief counseling and usual care. The study found no significant improvements in cognitive performance or other secondary outcomes, leaving its long-term effects on dementia prevention uncertain.

High-fat diets in mouse parents alter offspring brain development

Researchers fed breeding pairs of mice five diets with different fat and sugar contents to examine how parental nutrition affects offspring brain development. High-fat diets, alone or combined with high sugar, delayed early motor development and altered brain structure in young adult offspring, while the high-sugar-only diet produced no significant changes in individual brain regions after correction for multiple comparisons.

Ketones may change sleep patterns, but not always for the better

Researchers reviewed animal and human studies and found that ketone bodies may affect sleep stages through energy metabolism and cellular signaling, with the clearest direct evidence involving acetoacetate in mice. They reported mixed human findings and called for controlled studies to separate ketone-specific effects from changes linked to diet, disease, circadian timing, and physiological stress.

CT scans linked vitamin D levels to fat within muscles after bariatric surgery

Researchers followed 113 adults for one year after bariatric surgery and found that those with higher postoperative vitamin D concentrations had less fat infiltration within certain muscles and lower visceral adiposity. They found no significant association between increases in vitamin D and changes in body composition after correction for multiple comparisons, while preoperative vitamin D levels did not independently predict postoperative body composition.

Most adults with obesity did not meet food noise criteria in US survey

Researchers analyzed responses from 3,646 US adults not currently taking GLP-1 medications to assess persistent, unwanted food-related thoughts using a five-item questionnaire. They found that approximately 4% to 9.5% met questionnaire-based criteria for food noise, with higher scores among younger adults, women, and people in higher BMI categories, while cautioning that no clinically validated threshold exists.

Men with lower testosterone at 31 reported good health 15 years later

Researchers analyzed testosterone concentrations measured at age 31 in 2,691 Finnish men and assessed self-reported health, medical conditions, and quality of life at age 46. Men across testosterone quartiles generally reported good health and excellent quality of life, while differences in metabolic and gastrointestinal conditions lost statistical significance after adjustment for waist circumference.

Endometrial cancer rates rise sharply among younger South Texas women

An Upper-South region of Texas including San Antonio and Bexar County had the state's highest hysterectomy-corrected incidence of endometrial cancer and the largest increase over time, a study led by scientists at The University of Texas at San Antonio Health Science Center and the National Cancer Institute showed.

High intake of saturated fat can promote favorable changes in cardiovascular risk markers

New analyses from the Norwegian randomized controlled trial CARBFUNC show that more than doubling saturated fat intake over a two-year period can promote favorable changes in several cardiovascular risk markers, without increasing apoB, the main suspected risk factor.

Semaglutide changes gut bacteria in rats beyond what eating less explains

Researchers compared semaglutide-treated male and female rats with pair-fed animals receiving the same amount and type of food to distinguish drug-associated microbiome changes from those linked to reduced eating. Semaglutide altered bacterial richness and community composition, with some changes absent from the pair-fed groups and uncertain consequences for health.

New report urges unified lifecycle approach to women's heart health

A new approach to women's heart health may offer them a lifetime of opportunities. A trio of scientific papers, published today in the journal Circulation, spells out how fluctuating hormones, mental health and well-being, the heart and the brain are linked and how those connections need to be a routine part of care from a young age.

Understanding the symptoms and treatments of pelvic organ prolapse

The pelvic floor is a layer of muscles and connective tissues that supports the uterus, bladder, urethra, vagina and rectum. The pelvic floor supports the organs in your pelvis from underneath, almost like a hammock.

Taking a GLP-1 drug? Here's what the safety evidence really shows

A review on GLP-1 receptor agonists highlights risks like pancreatitis and thyroid cancer, emphasizing individual patient risk over general safety concerns.

Can happy feelings trigger eating too? Researchers explored both sides of emotional eating

Among 3,834 members of weight-management programs, greater recent weight loss was associated with less emotional eating, fewer food cravings, and better mood. Participants identified distraction, meal planning, healthier food swaps, and group support as helpful strategies, but the observational study could not establish whether these approaches caused weight loss.

Beer, wine or spirits: A large study finds different mortality patterns for each

Researchers analyzed data from 340,924 UK Biobank participants and found that high total alcohol consumption was associated with greater all-cause, cardiovascular, and cancer mortality, while moderate consumption was linked to increased cancer mortality. Beer/cider and spirits showed associations with higher mortality across several outcomes, whereas low-to-moderate wine consumption was linked to lower mortality for certain outcomes, though the observational study cannot establish causation.

Study: Cats on vegan diets show lower rates of obesity

A large-scale survey has found cats fed vegan diets had lower rates of obesity and related health problems, than those fed conventional meat-based diets.
