Heart disease is the leading cause of death in modern society.

It is a broad category of diseases, the most common of which are heart attacks and strokes.

The relationship between alcohol and heart disease is complex and depends on several factors.

Light to moderate drinking is linked to a reduced risk of heart disease, while heavy drinking appears to increase the risk (37Trusted Source, 38Trusted Source, 39Trusted Source, 40Trusted Source).

There are several possible reasons for the beneficial effects of drinking moderately.

Moderate alcohol consumption may:

Raise “good” HDL cholesterol in your bloodstream (41Trusted Source).
Decrease blood pressure, a major risk factor for heart disease (42Trusted Source).
Lower your blood concentration of fibrinogen, a substance that contributes to blood clots (43Trusted Source).
Cut the risk of diabetes, another major risk factor for heart disease (44Trusted Source).
Reduce stress and anxiety temporarily (41Trusted Source, 45Trusted Source).
SUMMARY
While moderate alcohol consumption may reduce your risk of heart disease, heavy drinking may increase it.
Type 2 Diabetes
Type 2 diabetes affects about 8% of the world’s population (46Trusted Source).

Characterized by abnormally high blood sugar, type 2 diabetes is caused by a reduced uptake of glucose, or blood sugar, by your cells — a phenomenon known as insulin resistance.

Drinking alcohol in moderation appears to reduce insulin resistance, fighting the main symptoms of diabetes (47Trusted Source, 48Trusted Source, 49Trusted Source, 50Trusted Source).

As a result, drinking alcohol with meals may cut the rise in blood sugar by 16–37% more than water. Blood sugar between meals — known as fasting blood glucose — may also decline (51Trusted Source, 52Trusted Source).

In fact, your overall diabetes risk tends to drop with moderate alcohol consumption. However, when it comes to heavy drinking and binge drinking, your risk rises (53Trusted Source, 54Trusted Source, 55Trusted Source, 56Trusted Source).
