I'll admit to being skeptical on resveratrol, despite some interesting science lurking in there somewhere - the compound appears to pull some of the same biochemical triggers as calorie restriction. This EurekAlert report looks at research in short-lived fish: "Recently, a small fish species with a captive lifespan of only three months was described by Cellerino and colleagues. In the new work, the researchers used this short-lived fish to test the effects of resveratrol on aging-related physiological decay. The researchers added resveratrol to daily fish food and found that this treatment increased longevity and also retarded the onset of aging-related decays in memory and muscular performance." Of course, there's always the possibility that they failed to control for actual calorie restriction - that happens a lot.
