The health benefits of resveratrol, a compound found in the skin of grapes (and thus in red wine), have long been known. Studies have indicated that it serves as an antioxidant, that it has anti-tumor properties, that it can help you live longer, and that it may be responsible for the "French paradox" (the French have a high-fat diet and yet low instances of health disease). A new study examined resveratrol's effects on melanoma, and found that it has anti-cancer properties. Cool! But, well, ignore.
First question: has resveratrol been proven to fight cancer? First answer, to that first question: Resveratrol has been studied significantly, but never in a clinical trial on humans. Yes, it's been tried on rats and mice, but only clinical trials on humans can say for sure whether a compound has a proven effect….. To get the amount of resveratrol from wine to equal the amount given to the animals in these studies, you'd be dead from alcohol poisoning a few times over. Red wine has about 160 µg of resveratrol per ounce. Assuming each glass of wine has about five ounces, that's 800 µg per glass, or 0.0008 grams…..To read More….. http://www.popsci.com/article/science/can-red-wine-really-heal-cancer-and-prolong-your-lifeEditor’s Note – µg and mcg are both symbols for 'micrograms'. The correct symbol for microgram is actually µg. However, there is no way of typing that on a keyboard, so they came up with other versions, two of which are µg and mcg.
