Low-density lipoprotein, or LDL, is a type of cholesterol linked to heart disease. LDL cholesterol causes a fatty buildup in your arteries that can eventually block the flow of blood and oxygen to the heart, so it is important to keep your LDL levels low. Research has shown one method of lowering LDL is by consuming a small glass of red wine daily.
LDL
LDL cholesterol is a strong risk factor for heart disease. The higher the level of LDL in the blood, the higher the risk for heart attack and stroke. The average person should keep his LDL under 100 mg/dl, and those with known heart disease should keep their levels under 70 mg/dl.
Benefits of Red Wine
Recent scientific studies have looked at the effects of red wine on heart health and determined that the flavonoids in red wine can lower LDL. These antioxidants protect the cells in the walls of the arteries, preventing damage from LDL. Red wine also decreases LDL production. In addition, red wine also contains the phytochemical resveratrol, which may decrease LDL levels. This substance is still under study for its health benefits.
Types of Wine
Some types of red wine are more beneficial than others. Yale-New Haven Hospital reports wines with higher amounts of flavonoids have stronger LDL-lowering effects. These wines include cabernet sauvignon, petit syrah and pinot noir. Studies have shown merlot and red zinfandel do not contain as many flavonoids. The dryer the wine, the more flavonoids it contains.
Precautions
Consume wine in moderation. Stick to one 4-oz. serving of wine a day if you are a woman, and two servings if you are a man. Consuming large amounts of alcohol can cause liver, kidney and other organ damage. Always check with your doctor before you add wine to your diet, as it could interfere with other medications you are taking.
