Doctor Oz announced recently on his popular syndicated television program, The Dr. Oz Show, that he was personally testing the benefits of resveratrol.
Many benefits, real and imagined, have been attributed to resveratrol, which is an antioxidant found in red wine.
On one hand, tests have shown increased good cholesterol, reduced blood clots and prevention of arterial damage.
In addition, resveratrol contributes to a reduction in diabetes, bad cholesterol and helps to protect the lining of blood vessels.
Strong benefits indeed!
On the other hand, the results were obtained from tests on animals, principally mice.
Thus the American Heart Association does not recommend ingesting red wine strictly for benefits attributed to resveratrol without additional testing.
Also, similar benefits have been determined from all alcohol, not just red wine.
Alcohol in moderation is generally accepted to provide health benefits including increased good cholesterol.
Moderation is defined for men as 24 ounces of beer, 10 ounces of wine at 5 oz each or 3 ounces of alcohol over 80 proof. (For women, limits are 12 ounces of beer, 5 ounces of wine and 1.5 ounces of 80 proof alcohol). In addition to generally weighing more than women, men also have more of an enzyme that metabolizes alcohol.
In addition to the potential benefits of resveratrol, wine includes:
– Iron (4% of Daily Requirement)
– Potassium (5%)
– Manganese (10%)
– 125 Calories (red wine, 5 ounces)
Specifically the benefits associated with resveratrol come from the skin of the grape. The beneficial antioxident, or flavonoid, is contained in the skin of a red grape. Red grapes are fermented longer than white grapes and the increased process time harvests the polyphenol, or powerful antioxidant, component.
Doctor Oz stated that he recognizes the potential benefits of resveratrol and will test the benefits himself. Although he did not specifically state that how he would complete the test, it could be expected that he would take a resveratrol supplement rather than drinking red wine.
Will Doctor Oz give resveratrol a ringing endorsement? If so, expect sales to take off like a rocket ship. As Vice-Chair and Professor of Surgery at Columbia university and director of the Cardiovascular Institute at New York Presbyterian Hospital, he is considered an expert on heart health.
What if Doctor Oz finds little or no benefit? In that case we may not be talking about resveratrol again until conclusive tests are completed and the American Heart Association weighs in.
