Adding to evidence that a little wine can do a heart good, a new study suggests that women who drink moderate amounts may have less inflammation in their blood vessels.
Spanish researchers found that after four weeks of drinking two glasses of wine per day, women showed lower levels of certain inflammatory substances in their blood. The findings, reported in the American Journal of Clinical Nutrition, suggest a mechanism by which wine -- particularly red wine -- may protect the heart.
Numerous studies have found that wine drinkers tend to have lower rates of heart disease than teetotalers do. Research also suggests that higher levels of "good" HDL cholesterol may be one reason, though not a full explanation of the benefit.
Figuring out exactly how wine may protect the heart is important in order to prove that the link between wine and heart health is, in fact, a direct one, according to Dr. Emilio Sacanella, the lead researcher on the new study.
