Fermented dairy was linked to lower mortality, but the pattern shifted at higher intakes

Analysis of 37,366 US adults found that fermented dairy consumption was associated with lower all-cause and cardiovascular mortality, with consumers showing adjusted hazards 18% and 20% lower, respectively, than non-consumers. Dose-response analyses indicated that the inverse association was concentrated at intakes below about 150 grams per day, while the observational study could not establish causality.

Finnish adults eat too little of some foods and too much of others, study finds

Analysis of dietary data from 1,655 Finnish adults found that usual food intake often differed substantially from the quantitative targets later set by the Nordic Nutrition Recommendations 2023. Plant-based foods were generally underconsumed, while red and processed meat and dairy intake frequently exceeded study targets, with adherence varying by sex, education, physical activity, age, and energy intake.

Exercise usually helps the brain. During a 15-day fast, the story was different

In a 28-day controlled study of 22 healthy adults, 15 days of complete fasting produced a glucose-to-ketone metabolic shift and selectively affected attention and implicit learning while time perception remained relatively stable. Moderate-intensity exercise during early fasting was associated with poorer performance on some learning measures, while fasting also increased sleepiness and reduced calmness at some time points.

Tirzepatide vs semaglutide for asthma: the difference was smaller than researchers expected

In a US multicenter electronic health record study, researchers compared tirzepatide with semaglutide in adults with asthma and type 2 diabetes, matching 8,176 patients in each treatment group. Asthma exacerbation risk was similar between treatments, while tirzepatide was associated with a lower likelihood of receiving a short-acting beta-agonist prescription.

An 8-hour eating window stood out for weight loss, but the full picture is more complicated

A pooled analysis of individual data from five time-restricted eating trials involving 124 adults linked shorter eating windows with modestly greater weight loss. Eight-hour TRE was associated with greater weight loss than 12-hour TRE and controls, while cardiometabolic outcomes showed no consistent relationship with eating-window duration and several weight associations weakened after adjustment.

More data, more answers? A 1.9 million-person health study shows why scale has limits

Researchers analyzed phenotypic and linked health-record data from more than 1.9 million adults in Our Future Health, comparing demographic characteristics, disease patterns, clinical associations, and rare-condition case counts with national data and other major cohorts. The cohort's size provides unusually large samples for many common and less common conditions, although its demographic composition and current data sources require careful consideration when interpreting population-level estimates.

Coffee after colorectal cancer? Decaf and caffeine show different links with mortality

In a prospective analysis of 1,098 people with colorectal cancer, researchers found no significant association between total or caffeinated coffee intake and all-cause or colorectal cancer-specific mortality in the cohort overall. Decaffeinated coffee was associated with lower all-cause mortality, while the highest quartile of caffeine intake was associated with lower all-cause and colorectal cancer-specific mortality, although the observational study cannot establish causation.

Refined starch activates immune pathways after low-carb weight loss

After substantial weight loss on a very-low-carbohydrate diet, participants who switched to a diet rich in refined starch showed greater activation of circulating immune and metabolic pathways than those who continued the low-carbohydrate diet or consumed a high-carbohydrate diet rich in added sugar. Mouse experiments suggested that activation of the complement immune pathway may help explain the inflammatory response associated with starch intake.

Women use creatine differently from men, survey reveals

A cross-sectional survey of 2,094 current or recent creatine users found that women were more concentrated in shorter-duration use groups than men and reported different supplementation goals, information sources, and knowledge patterns. Women were less likely to cite athletic performance and more likely to cite healthy aging as a goal, while researchers cautioned that the survey design cannot explain why these differences exist.

Rentosertib shifts multiple proteomic aging clocks toward younger age profiles in IPF trial

Researchers applied six proteomic aging clocks to serum samples from a phase 2a trial of rentosertib in people with idiopathic pulmonary fibrosis and found treatment-associated shifts toward younger predicted biological-age profiles, particularly with the 30 mg twice-daily regimen. Additional proteomic analyses linked treatment to changes in senescence, metabolism, growth-factor signaling, and fibrosis-related pathways, although the study could not determine whether these effects reflected genuine geroprotection rather than disease modification.

The link between fish and pregnancy hypertension may start before conception

In a nationwide Japanese cohort of more than 86,000 women, higher fish intake before pregnancy was associated with lower odds of early-onset hypertensive disorders of pregnancy, while fish intake during pregnancy showed different associations with late-onset disease, particularly among women who had not previously given birth. Total dietary omega-3 and omega-6 PUFA intake showed much less consistent associations, suggesting that the relationship with fish consumption may not be explained by total PUFA intake alone.

Why a shorter eating window may not mean better metabolic health

In a nationally representative cross-sectional study of 16,973 Korean adults, researchers identified three distinct eating patterns based on the timing and distribution of daily energy intake. Eating later within a shorter daily window was associated with higher odds of metabolic syndrome, elevated blood pressure, triglycerides, and fasting glucose, while frequent grazing showed a mixed metabolic profile.

Stevia tastes sweet, but does your body react as if sugar is coming?

In a randomized, double-blind crossover study, researchers tested stevia alone and with glucose in adults with normal weight, overweight, or type 2 diabetes to assess acute effects on blood glucose, insulin, gut hormones, appetite, and subsequent food intake. Stevia produced no significant changes in the measured glycemic or hormonal responses compared with water and did not significantly modify responses to glucose, while appetite and subsequent energy intake were also generally unchanged.

Working shifts may change more than your sleep schedule

A cross-sectional analysis of 1,814 Japanese workers found that shift work was associated with lower raw seafood intake and shorter sleep patterns in both sexes, while female shift workers also consumed less milk and dairy products. Total energy intake was similar between work groups, but male shift workers were more likely to consider preference and convenience when choosing foods, highlighting potentially important differences in dietary quality and lifestyle rather than calorie intake.

Could one amino acid help explain why men tend to live shorter lives?

A UK Biobank cohort and Mendelian randomization study involving 272,475 participants linked higher circulating tyrosine with greater all-cause mortality and genetically predicted higher tyrosine with shorter lifespan. After accounting for phenylalanine, the relationship with shorter lifespan was clearest in men, while findings in women were less consistent, suggesting a potential sex-specific role for tyrosine in longevity.

What mothers eat in pregnancy may shape a child’s weight years later

A prospective study of 252 mother-child pairs found that higher combined maternal fruit and vegetable intake during pregnancy was associated with lower odds of overweight or obesity in children at age four. Total and natural fruit juice showed no association, whereas higher commercial fruit juice intake was associated with increased odds, though the authors emphasized that this finding was exploratory.

What four pregnancy eating patterns revealed about mothers and newborns

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.
