Breast cancer has become a common disease among women and a serious threat to their health. According to research findings, about one-third of cancer incidence is related to diet. Food with a reasonable mix has a preventive effect on cancer, so what can be eaten to effectively prevent breast cancer? 1, mango Mango, it is commonly known for its antioxidant effect, but American scientists found that mango also has the effect of preventing or inhibiting certain types of colon cancer and breast cancer. Researchers have studied the polyphenols in mangoes, especially the bioactive component tannins (related to cancer prevention and inhibition). Tannins are polyphenols with a bitter taste, which are found in grape seeds and tea leaves. Studies have found that the cell division cycle is broken due to polyphenols. This may be a mechanism for mangoes to prevent or inhibit cancer cells. 2, kiwi The kiwi is a precious fruit, with 4-2 times the vitamin C content of oranges, 3 times that of apples and 60 times that of grapes. Research shows that the substances it contains can block the production of nitrosamines in the body, thus having a good anti-cancer effect, is a good prevention of breast cancer. 3, legumes Bean pods, lentils, peas, etc. are rich in nutrients, low in fat, high in protein, and rich in a variety of antioxidants and saponins. These foods are good for the whole body and add strength to the fight against breast cancer. Soybeans and soy products are the best alternative to animal protein. Soy foods contain soy isoflavones that prevent breast cancer and are best to start consuming them before puberty. One study pointed out that premenopausal women who ate moderate amounts of soy reduced their risk of breast cancer by 50%. Carrots are rich in carotenoids, which can be converted into vitamin A after intake. Vitamin A can maintain the normal structure and function of human epithelial tissues, making it difficult for carcinogens to invade, and can stimulate the immune system to mobilize the body’s ability to fight cancer, while affecting the metabolism of carcinogens and having a biological antagonistic effect with carcinogens. It is especially suitable for the prevention and treatment of breast cancer, and can be taken for a long time, but it is best to consume carrots fried in oil, so as to facilitate the absorption of carotenoids.
