The compound that makes red wine a healthful drink may also hold the secret to a longer life, scientists reported on Wednesday.
They found that resveratrol acted on fruit flies and worms in the same way as a method known to extend the life of animals including monkeys - sharply restricting how much they eat.
The finding opens the possibility that people could take a pill to achieve the same benefits as strict dieting to live longer, healthier lives, said David Sinclair of Harvard Medical School in Boston, who led the study.
