- Fish oil supplements linked to slower brain repair in some patients, study finds
A study suggests fish oil supplements, particularly their EPA component, may slow brain repair in individuals with repeated mild head injuries by destabilizing blood vessels and blocking repair signals, while also increasing tau protein buildup linked to brain diseases. Researchers emphasize that effects are context-dependent and findings are based on mice studies.
- Natural hormone may reduce obesity without cutting calories, scientists say
Researchers at the University of Oklahoma discovered a hormone called FGF21 that may reduce obesity in mice by increasing metabolic rate without calorie restriction. The study, published in Cell Reports, shows FGF21 targets the hindbrain to regulate metabolism, similar to GLP-1 drugs, but with distinct mechanisms. However, experts caution that results in mice may not translate directly to humans due to differences in FGF21 behavior.
