Understanding the risks and any possible health benefits of alcohol often seems confusing; that's understandable, because the evidence for moderate alcohol use in healthy adults isn't certain.

Researchers know surprisingly little about the risks or benefits of moderate alcohol use in healthy adults. Almost all studies of lifestyle, including diet, exercise, caffeine, and alcohol, rely on patient recall and truthful reporting of one's habits over many years. These studies may indicate that two things may be associated with one another, but not necessarily that one causes the other. It may be that adults who are in good health engage in more social activities and enjoy moderate amounts of alcohol, but that the alcohol has nothing to do with making them healthier.

Any potential benefits of alcohol are relatively small and may not apply to all individuals. In fact, the latest dietary guidelines make it clear that no one should begin drinking alcohol or drink more often on the basis of potential health benefits. For many people, the possible benefits don't outweigh the risks and avoiding alcohol is the best course.

On the other hand, if you're a light to moderate drinker and you're healthy, you can probably continue to drink alcohol as long as you do so responsibly.

Here's a closer look at alcohol and your health.
