With moderate, responsible alcohol consumption, the likelihood of developing cardiovascular disease, as well as the likelihood of dying from cardiovascular disease or other reasons, can be reduced by up to 30%, especially in men over 40 and postmenopausal women, for whom the risks of heart disease and strokes are higher. However, with every drink that exceeds the limits of responsible consumption, the same odds increase enormously. The consumption of larger quantities than those mentioned in the directives has no greater advantages but entails greater risks.
Alcohol can protect against cardiovascular disease because it simply "thins the blood", and therefore helps to reduce harmful clots and narrowing of the arteries. Small amounts of alcohol also stimulate the liver to produce “good” cholesterol (HDL) which in turn dissolves the “bad” cholesterol (LDL).
This, of course, happens with a small quantity of alcohol. One drink is enough and its positive effect lasts for about 24 hours.
According to several studies, very moderate consumption by middle-aged and elderly people can have health advantages, such as a reduced risk of dementia, Alzheimer's, osteoporosis, and type 2 diabetes mellitus. However, consuming larger amounts can cause an increase in blood pressure and affect the control of diabetes, thereby increasing the risk of stroke and heart attacks.
