from "Rust Out" by Dr. Royce Bailey, page 176
The promotion of alcohol consumption as a preventive measure against heart disease has been a strategy of the alcohol industry for several years. But the truth lies in the grape, not the alcohol!
A recent study showed that the flavonoids (quercetin), found in the skin, stems, seeds of the grapes and in wine processing, are responsible for the reduced “stickiness” of the blood platelets and therefore, less heart attacks. Grape juice was as effective as red wine (with or without its alcohol content) in study participants’ platelet activity. The lining to their blood vessels was more stable (less sticky) and the blood vessel was seen to dilate, even after only short-term ingestion, thus protecting from clogged arteries.
Those who ingested six ounces of purple grape juice were protected from oxidation (rusting effect) of their bad cholesterol (LDL), even while taking Vitamin E.
