"Beer keeps you younger, but may give you cancer."
There are notable health benefits associated with a moderate level of beer consumption: it raises HDL ("good cholesterol"), helps prevent cardiovascular disease, decreases the likelihood of dementia, and in general counteracts some of the risks of aging. Of course, all of this only applies when people drink in moderation (fewer than five drinks when one indulges; one to six beverages over the course of a week). However, averaging a drink a day also increases your risk for several types of cancer, including lung, liver, stomach, and prostate cancer.
