Grape Skin Protein Kills Cancer Cells

Resveratrol is an antioxidant found in a number of plants, including grape skins, raspberries, mulberries and peanuts. This compound is known to have a number of benefiical health effects, including fighting cancer as I wrote back in 2002. Now researchers have found how resveratrol fights cancer--it helps to starve cancer cells by inhibiting the action of a key protein that feeds them. Previous studies have also shown that resveratrol can help control atherosclerosis, heart disease, arthritis, and autoimmune disorders.

In nature, resveratrol fights fungus in plants during the rainy season, and it is especially prevalent in grapes used in making red wine. The researchers said the resveratrol in one glass of wine three or four times a week is the right amount to block the protein from feeding cancer cells, but drinking much more than that can lead to an increased risk of cancer.
