That fruit, vegetables and red wine good for the prevention of cardiovascular diseases is
known for years. And that vegetarian diet reduces the incidence of tumors,

Scientists have obtained the substance from the root extract of a Peruvian tree

that resveratrol dose-dependent in mice counteracts the development of skin cancer
