We're starting to suspect that "scientists" is academic speak for "winos": after telling you to go ahead and drink a bottle of wine a day, they're now saying red wine is actually good for your memory.
Like dark chocolate, red wine has a compound called resveratrol that apparently has some great health benefits. A team at the Charité University in Berlin looked at the effects of resveratrol in overweight adults and found that the ones who got the compound daily rather than a placebo had a much easier time remembering stuff. It should be noted that this was a small study of 46 people, so researchers are definitely going to have to dip back into the wine cellar and return with more data to back this up. But at this rate, you might as well consider a glass of Malbec to count as vitamins.
