A Healthy Diet May Still Make a Difference for People at Higher Risk of Dementia
Researchers tracked nearly 1,900 Swedish adults aged 60 and older for up to 15 years, finding that healthier dietary patterns were associated with a lower risk of developing dementia. The protective effect persisted even among participants with blood biomarkers indicating higher biological risk, especially when diets had low inflammatory potential, cutting relative risk by up to 30%. Different diet quality measures—Mediterranean, general healthy guidelines, and inflammatory potential—showed varied benefits depending on biomarker levels. The study is observational, so it cannot establish causality.
Can't Exercise? Sulforaphane From Broccoli Sprouts Reverses Frailty in Aging Mice
A recent Science Advances study showed that sulforaphane, a compound from broccoli sprouts, can reverse frailty phenotypes in aging mice when administered intraperitoneally at 2 mg/kg three times a week. Translating that exposure to humans yields an estimated systemic dose of...
Effect of Acute Dietary Nitrate Intake on Post-Activation Performance Enhancement in Male Long Jumpers
A randomized, double‑blind crossover trial examined whether acute dietary nitrate from beetroot juice (9.22 mmol nitrate) enhances the post‑activation performance enhancement (PAPE) elicited by squats performed with a 5% velocity‑loss threshold in 20 male long jumpers. All conditions produced significant improvements...
