What happens when alcohol non-drinkers begin to drink? Researchers at the Medical University of South Carolina have found that middle-aged non-drinkers who began drinking in moderation experienced a 38% lower risk of developing cardiovascular disease compared to those who continued abstaining.
The investigators found that 6% began consuming alcohol in moderation. That is, up to one drink per day for women and up to two drinks per day for men. during the follow-up period.
After 4 years of follow-up, new moderate drinkers had a 38% lower chance of developing cardiovascular disease than did the non-drinkers. Even after adjusting for physical activity, Body Mass Index, demographic and cardiac risk factors, 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
In addition, there is other evidence that alcohol reduces the risk of cardiovascular disease. Specifically, some of the ways it does so are understood.
Alcohol reduces blood clotting. It does so 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.
In addition, alcohol helps in other ways. It reduces both blood pressure and insulin levels. It also 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.
