A recent study tested the health benefits of resveratrol, a compound found in red wine and chocolate, to see it affords the same health benefits for humans as had previously been found for other animals.
Unfortunately for you wine lovers out there, no association was found with inflammation markets, cardiovascular disease, cancer, or all-cause mortality. This doesn’t necessarily mean that red wine is bad for you (other beneficial elements could exist), but you probably have less cause to pat yourself on the back the next time you drink.
