DEAR DOCTOR K: I've heard that drinking red wine, or any alcoholic beverage, in moderation is "heart-healthy." Is it true, and is red wine any healthier than other alcoholic beverages?
DEAR READER: There are many studies of the two questions you ask. As for the first question, most studies have found that moderate drinkers are less likely to develop Type 2 diabetes and heart disease. That's when moderate drinkers are compared either to non-drinkers or to heavy drinkers.
