The Magical Grape And Whole Seeds
A study conducted by the University of California, Irvine, showed that patients with colon tumors who consumed 80 mg of grape powder each day which by the way equivalent of half a glass of wine or three servings of grapes had a considerable decrease in cancer activity in the tumors revealed by biopsies.
The researchers believe consuming grapes may help prevent colon cancer, which is the third most common type of cancer in the United States. Even if cancer is not a concern for you, a bunch of grapes is an easy on-the-go snack to pack in your cooler every day. The antioxidants added to your diet won't hurt either.
Although the researchers say that it is too early to draw conclusions that grape seed may reduce the risk of cancer in humans, this is because in vitro and in vivo studies conducted to date have found that grape seed extract (especially proanthocyanidins extracted from grape seeds) appeared to have anti-cancer properties.
Even in the animal tests using mice, grape seed extract is proven to provide effective protection against UV-induced photocarcinogenesis by reducing the incidence of tumors, tumor size, tumor multiplicity and by preventing UVB-induced transformation of papillomas to carcinomas are malignant.
And for this reason the effects of UV-induced photocarcinogenesis has been heavily linked with the potent antioxidant properties of proanthocyanidins from grape.
