A glass of red wine a day keeps the doctor away

 



Is red wine the fountain of youth or a potent poison? Is enjoying a glass of red wine with dinner each evening beneficial to your health? Current research suggests that a glass of red wine each day may be providing you with more than just a little relaxation.

What are the health benefits of drinking red wine?

For over 10 years, research has indicated that moderate intake of alcohol improves cardiovascular health. In fact, in 1992 Harvard researchers included moderate alcohol consumption as one of the "eight proven ways to reduce coronary heart disease risk." However, research has suggested that specifically red wine is the most beneficial to your heart health. The cardioprotective effect has been attributed to antioxidants present in the skin and seeds of red grapes.

Scientists believe the antioxidants, called flavonoids, reduce the risk of coronary heart disease in three ways:

•   by reducing production of low density lipoprotein (LDL) cholesterol (also know as the "bad" cholesterol)
•   by boosting high density lipoprotein (HDL) cholesterol (the good cholesterol)
•   by reducing blood clotting. Furthermore, consuming a glass of wine along with a meal may favorably influence your lipid profiles following that meal

Recently, researchers have found that moderate red wine consumption may be beneficial to more than just your heart. One study found that the antioxidant resveratrol, which is prevalent in the skin of red grapes, may inhibit tumor development in some cancers. Another study indicated that resveratrol aided in the formation of nerve cells, which experts believe may be helpful in the treatment of neurological diseases like Alzheimer's and Parkinson's.

Which wines should you consume to reap the most benefits?

Researchers at the University of California, at Davis tested a variety of wines to determine which types have the highest concentrations of flavonoids. Their results concluded that the flavonoid favorite is Cabernet Sauvignon, followed closely by Petit Syrah and Pinot Noir. Both Merlots and red zinfandels have fewer flavonoids than their more potent predecessors. White wine had significantly smaller amounts than the red wine varieties. The bottom line is the sweeter the wine, the fewer the flavonoids. Dryer red wines are your best bet for a flavonoid boost.

How much red wine should I drink?

A four-ounce glass of wine is equivalent to one serving. Men will benefit from consuming one to two servings per day. Women should consume only one serving per day to reap the maximum benefits. This is not to say that you should start drinking alcohol if you presently do not. Occasional or binge drinkers have higher mortality rates than those who drink moderately on a regular basis. In those who consume three or more drinks per day, there is an increased risk for elevated serum triglycerides (fat in the bloodstream). Long-term, excessive alcohol consumption can damage nerve cells, the liver and the pancreas. Heavy drinkers are also at risk for malnutrition, as alcohol may substitute for more nutritious foods.

What if I have other health problems?

Recommendations to consume moderate amounts of wine are limited to individuals with a clean bill of health. It is clear that people with medical and social conditions worsened by alcohol should not consume any alcohol at all. Hypertryglyceridemia, pancreatitis, liver disease, uncontrolled hypertension, depression and congestive heart failure are diseases that may be worsened by alcohol. Those individuals at risk for these conditions should consult with their physician before consuming any alcohol at all.

What about grape juice and non alcoholic red wine?

 

In 1997, researchers at the University of Wisconsin concluded that purple grape juice also reduced blood clotting. Another study by researchers at University of California at Davis, confirmed the findings that non alcoholic red wine contains the same antioxidant profile as red wine. However in a 1998 study, Japanese researchers found that while grape juice still had antioxidative benefits, it did not significantly lower LDL cholesterol levels compared to red wine.

The debate continues on whether it is the components of the wine, the way the wine is consumed, or the lifestyle traits that is the most responsible for the long healthy lives of many wine drinkers. However, the evidence seems clear that regular, moderate consumption of red wine is beneficial to your health. So here's a toast to your health! Cheers
