Grapes

John's Hopkins has also looked at the effect of grapes on health. Grapes have been shown to have high antioxidant value. Red grapes contain polyphenolics and green grapes contain catechins, both of which have strong antioxidant effects. The polyphenolics in red grapes is contributed to the anthocyanins in the skin. For more info on anthocyanins, see my earlier posts here.

Green grapes contain catechins. Catechins are polyphenolics which are specifically flavon-3-ols. These are very potent antioxidant that decrease plaques in the blood vessels, thereby decreasing heart disease. They also decrease cancer.

A friend asked me if this is true, then is wine good for you. The answer is yes, but in moderation. To get beneficial effects from wine, red wine is better than white. Red wine can also assist in lowering angiotensin, which in turn decreases blood pressure. It can also assist in dilating blood vessels which assists cells in getting oxygenated blood and sustaining less damage from oxidation.
