The video below is somewhat lengthy, but it contains a good discussion of the human health effects of resveratrol.  Resveratrol is a molecule  found in various red wines that is purported to have positive health effects based on research on mice.   More study is needed to understand the true effects of this molecule on humans, but what we do know is that drinking alcoholic beverages to excess is not good for your health.   As with most things in life, a balance must be achieved between drinking wine to improve health and drinking wine to degrade health.  The video does go on to recommend what red wine would best meet resveratrol intake objectives.
