What happens when alcohol non-drinkers begin to drink? Researchers at the Medical University of South Carolina wanted to learn. They did a large study to find out.
They looked at middle-aged non-drinkers who began drinking in moderation. The researchers found a much lower risk of getting cardiovascular disease (CVD). That’s compared to those who continued abstaining.
The doctors found that 6% began moderate drinking. That is, up to one drink per day for women. It was up to two drinks per day for men. That was during the follow-up period.
After four years of follow-up, new moderate drinkers had a 38% lower chance of developing CVD than did the non-drinkers. The researchers adjusted for physical activity, Body Mass Index, demographic and cardiac risk factors. Yet this difference persisted.
This study is very important. It provides more evidence that the reduced risk of cardiovascular disease is a result of the alcohol itself.

How Alcohol Helps the Heart & Brain
Also there is other evidence that alcohol reduces the risk of CVD. That is, some of the ways it does so are understood.
Alcohol reduces blood clotting. It does this in several ways. First, it reduces blood platelet clumping. Second, it reduces the blood’s clotting substance. Finally, it increases the process of dissolving clots.
Alcohol also helps in other ways. It reduces both blood pressure and insulin levels. It reduces heart artery spasms. And it improves both estrogen levels and blood flow.
Abstaining from alcohol increases the chances for both poor health and earlier death. For more, see Alcohol and Health.
