A Toast to Healthy Hearts: Wine compounds benefit blood vessels

Researchers have identified a class of compounds in red wine that might be responsible for much of the beverage's cardiovascular benefit. These compounds vary in concentration among wines grown in different areas and may explain some regional differences in wine drinkers' longevities.

Some researchers have suggested that the common practice of drinking red wine at meals could explain why life expectancy in France tops that in many countries where people eat lighter fare. Recent studies have suggested that people who consume a glass or two of red wine each day have healthier cardiovascular systems than those who don't imbibe.
