More than eight drinks a week for women and 15 drinks a week for men can get you into trouble, the CDC warned.

But that doesn't seem to jibe with other studies that found that drinking alcohol makes for better heart health, several Shots commenters noted. Shana Cuddy wrote:

"Interestingly, in another NPR article they say that moderate drinkers are healthier overall than folks who don't drink at all, and they define 'moderate drinker' as someone who has 3 or less drinks per day. This would be 21 drinks per week for women, which this story claims is well over twice the safe limit."
