That's no big deal--in fact, it's healthy.
That it is. Long term negative consequences of moderate drinking (a loosely defined concept, but could be considered two standard drinks a day for the average person) is only the possibility that it can lead to heavy drinking. On the other hand, health benefits include (and I'll be happy to back up any of these):
- Increased HDL count
- Reduced symptoms of diabetes
- Reduced risk for heart disease
- Reduction of plaque formation associated with LDL oxidation
The benefits of heavy drinking, however, don't exist. As a college student, I used to be a pretty heavy drinker, and even did the 21-shot challenge on my 21st birthday. Coming across this information (I wrote a term paper on beer), however, made me realize that heavy drinking isn't only incredibly unhealthy, but it ruins the benefits of what has the potential to be a very good thing.
If it weren't for the potential for addiction, drinking beer wouldn't be much different than drinking milk. If, for example, you had 21 12oz cans of milk on your 21st birthday, you would likely suffer from the many symptoms associated with calcium poisoning, including the potential for a coma. On the other hand, long term negative side effects for use of milk are rare.
