Scientists found that resveratrol, long considered a "healthy" ingredient in red wine, helps fight some of the negative side effects of being weightless—and possibly of being sedentary. A batch of rats fed resveratrol in a space simulation didn’t develop insulin resistance or lose bone mineral density, effects that the rats not taking resveratrol suffered, the Daily Mail reports.
