A naturally produced molecule called resveratrol, found in the skin of red grapes, has been shown to lower insulin levels in mice when injected directly into the brain, even when the animals ate a high-fat diet. The findings from a new UT Southwestern Medical Center study suggest that when acting directly on certain proteins in the brain, resveratrol may offer some protection against diabetes. Prior research has shown that the compound exerts anti-diabetic actions when given orally to animals...

Resveratrol, a molecule found in red grapes, has been shown to improve diabetes when delivered orally to rodents. Until now, however, little has been known about how these beneficial changes are mediated in the body. A new study accepted for publication in Endocrinology, a journal of The Endocrine Society, shows that the brain plays a key role in mediating resveratrol's anti-diabetic actions, potentially paving the way for future orally-delivered diabetes medications that target the brain....

A healthy alternative to sugary snacks -- raisins -- may actually prevent tooth damage, U.S. researchers say. In addition to the polyphenols, flavonoids and iron in raisins, U.S. researchers also found germ-fighters that may suppress tooth disease. One of the many antimicrobial phytochemicals found in raisins -- oleanolic acid -- has been shown to suppress the tooth disease-causing Streptococcus mutans biofilm. Grape seed extract, high in proanthocyanidins, has been found to positively...

Could point the way toward production of European-tasting wines from American vines One of the best known episodes in the 8000-year history of grapevine cultivation led to biological changes that have not been well understood "“ until now. Through biomolecular detective work, German researchers have uncovered new details about the heredity of Vitis varieties in cultivation today. In the process, they have opened the way to more meaningful classification, accelerated breeding, and more...

In a study of rats, polyphenols in red wine or grape juice that help prevent Alzheimer's are absorbed better after continued ingestion, U.S. researchers say. Mario Ferruzzi, Connie Weaver and Elsa Janle of Purdue University in West Lafayette, Ind., and Dr. Giulio Pasinetti of Mount Sinai School of Medicine in New York say previous studies of a single or sporadic dose found little bioactive polyphenols reaching the brain. However, the study published in the Journal of Alzheimer's Disease,...
