Moderate drinking provides the best benefit for your health. Moderate drinkers live longer, have less diseases, and do better than those who don't drink or drink heavy.
If you don't drink or drink heavily, you'll likely to have shorter lifespan and more health problems than those who drink moderately.
"Moderate drinkers tend to have better health and live longer than those who are either abstainers or heavy drinkers. In addition to having fewer heart attacks and strokes, moderate consumers of alcoholic beverages (beer, wine or distilled spirits or liquor) are generally less likely to suffer hypertension or high blood pressure, peripheral artery disease, Alzheimer's disease and the common cold."
"Sensible drinking also appears to be beneficial in reducing or preventing diabetes, rheumatoid arthritis, bone fractures and osteoporosis, kidney stones, digestive ailments, stress and depression, poor cognition and memory, Parkinson's disease, hepatitis A, pancreatic cancer, macular degeneration (a major cause of blindness), angina pectoris, duodenal ulcer, erectile dysfunction, hearing loss, gallstones, liver disease and poor physical condition in elderly."
"Why drink to reduce the risk of heart disease? Wouldn't eating a good diet, exercising, and losing weight do the same thing?
No, it wouldn't. The moderate consumption of alcohol appears to be more effective than most other lifestyle changes that are used to lower the risk of heart and other diseases."
