Hiv Lifespan Outside The Body

A vegetarian diet helps prevent cancer. Studies of vegetarians show that death rates from cancer are only about one half to three quarters of the general population. The breast cancer rates are dramatically lower in countries where diets are typically plant-based. When people in those countries adopt a meat-based Western diet, their rates of breast cancer disparan.Los Vegetarians also have significantly less colon cancer than meat eaters. Meat consumption is more closely associated with colon cancer than any other dietary factor. Why vegetarian diets help protect against cancer? First, are lower in fat and higher in fiber than meat-based diets. But others factors are important, too. For example, vegetarians usually consume more of the plant pigment beta-carotene. This may help explain why they have less lung cancer. Moreover, at least one study has shown that natural sugars in dairy products may increase the risk of ovarian cancer in some women. Some anti-cancer aspects of a vegetarian diet can not be explained yet. For example, researchers are not quite sure why vegetarians have more of certain white blood cells called "killer cells" which are able to seek and destroy cancer cells.
