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

In two large US prospective cohorts, consuming more than one sugar-sweetened beverage a day was associated with higher gastric cancer incidence compared with consuming less than one serving a month. Artificially sweetened beverages were not associated with gastric cancer incidence, and the authors called for further studies to confirm the findings and clarify possible biological mechanisms.

Researchers examined whether prenatal exposure to aromatic amines and cotinine was associated with attention, processing speed, and memory in 250 infants assessed at 7.5 months. The study found mixed patterns across cognitive measures, with several estimates suggesting poorer attention or memory but carrying substantial statistical uncertainty.

 Beetroot juice may make swimming feel easier without making swimmers faster
 
Beetroot juice may make swimming feel easier without making swimmers fasterA systematic review and meta-analysis of 12 studies, with nine contributing data from 120 swimmers, found no significant improvement in swimming time-trial performance or post-exercise blood lactate with beetroot juice or dietary nitrate supplementation. Supplementation produced a small reduction in perceived exertion, but the effect varied across studies, and the certainty of evidence for swimming performance was low.

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