Heavy drinking negates benefits of moderate drinking
Now this is an interesting article; at least I think so. In the March 2010 issue of the American Journal of Epidemiology, researchers looked into the evidence of moderate alcohol consumption mixed with episodic heavy alcohol consumption. It is known that light to moderate alcohol consumption has a protective effect on the cardiovascular system. The findings in this article suggest that this benefit is lost when people drink heavily once a month. Heavy drinking was defined as more that 60gm of pure ethanol or 5 drinks per session. This brings up an interesting point. Previous studies covering moderate alcohol consumption may have not taken heavy drinking into account, which may lead to non-protective findings. This is relevant because even moderate drinkers have reported episodes of heavy drinking.
This is more evidence to suggest that drinking in moderation is still good for you, but don't overdo it. Don't forget to get your copy of this journal, I'm sure they are flying off of bookstore shelves.
