Alcohol dosing and the heart: updating clinical evidence.
Study Goal
The researchers aimed to evaluate the association between light/moderate alcohol consumption, particularly wine, and cardiovascular protection, while defining safe drinking limits.
Results Summary
The study found that light/moderate alcohol consumption, especially wine, is associated with reduced vascular and all-cause mortality, ischemic stroke, and other cardiovascular benefits. Wine, due to its antioxidant content, showed superior anti-inflammatory effects compared to other alcoholic beverages like gin.
Population
Healthy individuals and patients with cardiovascular disease, with specific considerations for men, women (including premenopausal and older women), and Mediterranean populations.
Effective Dosage
Up to 20 g/day (2 drinks) for men and 10 g/day (1 drink) for nonpregnant women; up to 2-3 drinks/day for men and 1-2 drinks/day for women with cardiovascular disease.
Duration

The consequences of heavy or irregular alcohol drinking have long been known. Recently, consistent information has been provided in support of an association between light/moderate alcohol consumption and protection from vascular and all-cause mortality, ischemic stroke, peripheral arterial disease, congestive heart failure, and recurrence of ischemic events. After reviewing the information with respect to major aspects of cardiovascular pathophysiology, to potential confounders and to underlying mechanisms, several concepts emerge. First, the recommended amounts of "safe alcohol drinking" in healthy individuals are up to two standard drinks (~20 g/d) for a man and up to one drink (10 g/d) for a nonpregnant woman. The overall balance for young premenopausal women, but not for older women, would be unfavorable for drinking. The risk of cancer would not outweigh potential benefits of alcohol on heart disease. Second, within the frame of a balanced pattern of dietary energy intake, patients with cardiovascular disease who drink alcohol should not exceed one or two standard drinks per day for women or up to two or three drinks per day for men. Third, the low rates of coronary heart disease among the Mediterranean people may be related to their pattern of drinking wine every day during meals. Regular drinking is associated with better outcomes than occasional (binge)/weekly drinking. Fourth, wine (ethanol with antioxidants) exhibits significantly higher anti-inflammatory effects than gin (ethanol without polyphenols), and thus in general wine should be preferred to liquor or beer.
