Writing this week in the online, open-access journal Public Library of Science (PLoS) ONE, researchers, including from the University of Florida, report that low doses of resveratrol — a natural constituent of grapes, pomegranates and red wine — can potentially boost the quality of life by improving heart health in old age. The scientists included small amounts of resveratrol in the diets of middle-aged mice and found that the compound has a widespread influence on the genetic causes of aging. Specifically, the researchers found that low doses of resveratrol mimic the heart-healthy effects of what is known as caloric restriction, diets with 20% to 30% fewer calories than a typical diet.
