The Nutritional Benefits Of Red Wine

Cabernet Sauvignon, Merlot and Pinot Noir are red wines. Red wines get their color from the skins of a variety of red and purple grapes during the fermentation process. A 5-oz. serving of red wine provides 3.6 g of carbohydrates and 120 calories. Red wine contains antioxidants and properties that raise good cholesterol, but the American Heart Association does not recommend drinking red wine to gain these benefits.

HDLs

High-density lipoproteins, known as HDLs, are considered good cholesterol because they act as scavengers, mopping up excess cholesterol in your blood. HDLs take this excess cholesterol to your liver where it is broken down. According to the American Heart Association, the best-known effect of red wine, taken in moderation, is an increase in HDLs. It is important to note that regular physical activity is another way to raise HDL levels.

LDLs

Low-density lipoproteins, or LDLs, carry cholesterol throughout your body to tissues and organs. When you have more cholesterol than your body needs, this excess cholesterol accumulates in your blood, where over time it can clog arteries and block blood flow, leading to heart disease. According to a study published in the "American Journal of Clinical Nutrition," consumption of red wine reduces the amount of LDLs circulating in the blood.

Resveratrol

Resveratrol is a polyphenol that can prevent blood platelets from sticking together and reduce damage to blood vessels. This may reduce clot formation and reduce the risk of heart attack or stroke. Most research has been conducted on animals, not humans, but animal results are promising. In animal studies, resveratrol extended the life and improved health of mice on a high-calorie diet, according to a 2006 study published in "Nature."

Antioxidants

Red wine contains several antioxidants like the polyphenol resveratrol. Antioxidants are substances that protect the body from free radical damage. Free radicals are the natural result of oxygen usage and can damage cells, which can contribute to disease. Antioxidants act as free radical scavengers, preventing cell damage. According to the Mayo Clinic, red wine contains more antioxidants than white wine and other types of alcohol.
