It had long been hypothesized that antioxidants might be able to protect against cancer because they neutralize reactive oxygen species (ROS) that can damage DNA. In laboratory and animal studies, the presence of increased levels of exogenous antioxidants has been shown to prevent the types of free radical damage that have been associated with cancer development. Most recently a 2011 trial of 35,500 men over 50 found that large doses of vitamin E increased the risk of prostate cancer by 17 per cent.

It had long been hypothesized that antioxidants might be able to protect against cancer because they neutralize reactive oxygen species (ROS) that can damage DNA. In laboratory and animal studies, the presence of increased levels of exogenous antioxidants has been shown to prevent the types of free radical damage that have been associated with cancer development. They protect the body from the damaging effects of free radicals (by-products of the body's normal chemical processes).
