Evidence was produced indicating that a nutrient called beta-carotene is able to block the mysterious process by which a normal cell turns malignant and cancerous. Scientists theorized that beta-carotene (along with Vitamins A, C, and E and the mineral selenium) actually inhibit the formation of cancer.
Studies were made that linked diet and the risk of cancer. Scientists found that the Japanses, who adhere to a traditional diet of vegetables and fish, have a low incidence of colon cancer. But when they migrate to the United States and adopt a Western diet burdened with meat and fat, their cancer rate rises dramatically.
Nutritionists suggest that the beta-carotene in vegetables should be included in everyone's diet to reduce the cancer risk.
The National Cancer Institute says in an official report: "In general, the evidence suggests that some types of diets and some dietary components (that is, high-fat diets or the frequent consumption of salt-cured, salt-pickled and smoked foods) tends to increase the risk of cancer. But low-fat diets or frequent consumption of certain fruits and vegetables tends to decrease cancer risks.
WHERE TO FIND BETA-CAROTENE
Many yellow and dark green vegetables, eaten raw, provide you with beta-carotene. Scientists call this substance a "provitamin A". Once you eat beta-carotene, it is converted to Vitamin A by your digestive and intestinal system.
Raw carrots are the richest source of beta-carotene and some nutritionists say half a cup of raw carrots at least three times a week is an appropriate serving.
Scientists have synthesized beta-carotene into a substance called 13-cis-retinoic acid. Derived from vegetables, this retinoic appears to inhibit bladder and breast cancer. Researchers are conducting extensive tests in the hope that it will also have important benefits for humans. </145494> http://a1itsinthebag.blogspot.com,http//www.orble.com/Winning,http://lindagjehoich.blogspot.com
