COLUMBUS, Ohio – Taking enough omega-3 fatty acid supplements to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests.
The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve tiny segments of DNA in their white blood cells. (more…)
GAINESVILLE, Fla. — Blueberry wine can provide more potentially healthy compounds than white wines and many red wines, according to a new University of Florida study.
Researchers with UF’s Institute of Food and Agricultural Sciences measured antioxidant content in a Florida-produced blueberry wine and compared it to published reports of antioxidant content in white and red wines made from grapes. Antioxidants are compounds that may offer cells protection from damaging molecules called free radicals. (more…)
Obesity is growing at alarming rates worldwide, and the biggest culprit is overeating. In a study of brain circuits that control hunger and satiety, Yale School of Medicine researchers have found that molecular mechanisms controlling free radicals-molecules tied to aging and tissue damage-are at the heart of increased appetite in diet-induced obesity.
Published Aug. 28 in the advanced online issue of Nature Medicine, the study found that elevating free radical levels in the hypothalamus directly or indirectly suppresses appetite in obese mice by activating satiety-promoting melanocortin neurons. Free radicals, however, are also thought to drive the aging process. (more…)
