 | | |  Beetroot supplement raises nitric oxide markers in triathletes after one week A randomized cross-over pilot study in 10 amateur male triathletes found that a beetroot-based multi-ingredient nitrate supplement increased nitric oxide-related and redox biomarkers over 7 days without evidence of lipid oxidative damage. The supplement was generally well tolerated, but the study did not measure whether these biochemical changes improved performance or recovery. | | | | |  Study shows why an apple a day may work differently for different people A 12-week single-blind trial in 38 Japanese adults found that daily Fuji apple intake did not significantly change overall host metabolic markers, but responses differed by baseline gut enterotype. Participants in the Bacteroidaceae-dominant enterotype showed significant increases in fecal short-chain fatty acids after apple consumption, suggesting that gut microbiota structure may shape functional dietary responses. | | | | |  Cola may quickly lower pH inside orthodontic clear aligners and shift oral bacteria within hours Researchers found that cola exposure quickly lowered pH and altered the microbiome on the inner surface of clear aligners, with the greatest disruption observed when aligners were removed before drinking and then reinserted. In this small 24-hour study, wearing aligners during exposure appeared less disruptive than removing them, though the authors said the mechanism still needs further study. | | | | |  Want muscle from creatine? Resistance training is the missing link A meta-analysis reveals creatine enhances high-intensity performance, with muscle gains linked to resistance training context and supplementation. | |

|  | | | | |  Dietitians report widely different strategies for FODMAP food reintroduction in IBS A national survey of 145 registered dietitians found wide variation in how the low FODMAP diet’s reintroduction phase is delivered, especially in dosing, timing, sequencing, and follow-up. The findings suggest that clearer, evidence-based protocols could improve consistency while still allowing individualized care. | |  | | | | |  When omega-3 may help mental health and when they may not Investigating omega-3 fatty acids, this review highlights their impact on mental health, inflammation, and the potential for therapeutic use in disorders. | | | | | | |  Parents’ intake of sugar substitutes may influence offspring gut biology, study finds A mouse study in Frontiers in Nutrition found that parental sucralose and stevia intake altered gut microbiota, short-chain fatty acids, and gene expression across generations, with sucralose showing the stronger and more persistent effects. The changes were transmitted to offspring not directly exposed to the sweeteners, although several effects were attenuated by the F2 generation. | |

| | | |  When you choose a diet version of your favorite fizzy drink, you consume non-nutritive sweeteners, which taste sweet but - unlike sugar - contain no calories. | | | | |  Adults with overweight or obesity taking the new generation of weight loss drugs semaglutide and tirzepatide tend to eat significantly less, leaving them vulnerable to nutritional deficiencies, according to one of the first real-world studies to examine dietary behavior in people using glucagon-like peptide-1 receptor agonists and dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) dual agonists RAs (collectively referred to as GLP-1... | | | | |  A large 23andMe-based GWAS found that common variants in GLP1R and GIPR help explain why some people lose more weight or experience more nausea and vomiting on GLP-1 drugs. The findings suggest genetics may eventually help predict who responds best to semaglutide or tirzepatide and who is more likely to develop side effects. | | | | | A new study finds that combining the current medications for Alzheimer's disease with small molecules derived from micronutrients found in grapes, berries, peanuts and turmeric is a safer and more effective way to treat the disease. | | | | | Eating a higher quality plant-based diet is associated with a lower risk of Alzheimer's disease and other related dementias compared to eating a lower quality plant-based diet, according to a study published April 8, 2026, in Neurology, the medical journal of the American Academy of Neurology. | | | | | Breastfeeding does not only affect your weight while you are breastfeeding. Women gain up to 6.5 kilos less on average later in life if they breastfeed for at least three months, according to a new study. | |
