A study published in the BMJ reports a correlation between drinking patterns and risk of coronary heart disease in women and men:
Women who drank alcohol daily had a lower risk of coronary heart disease than women who drank alcohol on less than one day a week. Little difference was found, however, between drinking frequency.
For men an inverse association was found between drinking frequency and risk of coronary heart disease across the entire range of drinking frequencies. The lowest risk was observed among men who drank daily (0.59, 0.48 to 0.71).
Doctors do not recommend people who do not drink to start using alcohol to prevent or treat any disease. If you already drink alcohol, and you have no alcohol-related problems or contraindications, you can continue using it in moderation.
