Toxic. Drinking more than three drinks per day, on the other hand, has been shown to have a direct and negative effect on the heart. Heavy drinking, especially in the long run, can cause high blood pressure, alcoholic cardiomyopathy, congestive heart failure, and stroke. Wine contains alcohol, which can harm your health if you drink too much of it. The amount of alcohol that you consume depends on how much wine you are drinking. One glass of wine contains about 1-2% alcohol, so it doesn't take many glasses to get drunk. A standard drink is defined as one unit of alcohol - such as beer, wine, or liquor - which contains 0.5 oz of alcohol. If you drink any amount of wine every day, it's going to be toxic to your body over time. Alcoholic liver disease, breast cancer, colon cancer, diabetes, infertility, nerve damage, violence, and weight gain are all related to excessive alcohol use. The best way to avoid poisoning your body with alcohol is not to drink it at all. If you must drink wine, do so in moderation (one glass or less per day for women, two glasses or less per day for men).
