Studies show that beans, grapes and grape juice inhibit cancer cell growth and slow tumor progression, while tomatoes and leafy vegetables, such as spinach, chicory, kale and Swiss chard, are effective for preventing cellular damage, reports Healthline. Anti-cancer properties are found in cruciferous vegetables, such as cabbage, broccoli and cauliflower.
Phytochemicals are helpful substances that fight against the development of cancer and are found in many plant foods, including berries, peppers, citrus fruits and soybeans, according to WebMD. High-fiber diets soften stools and help facilitate the rapid movement of toxic waste through the intestines, giving cancer-causing substances less chance to be absorbed by the intestinal cells. Beans, whole grain products, berries and fresh vegetables are excellent fiber and phytochemical-rich foods.
Studies show that calcium and Vitamin D may help prevent colon cancer, notes WebMD. Calcium is found in dark, leafy greens, such as mustard and collard greens, dairy products and sardines. Vitamin D-rich foods include egg yolks and salmon. Twenty minutes of natural sunlight a day is one of the best sources of Vitamin D. A low-fat diet is especially recommended for colon cancer prevention because high fat consumption produces large amounts of bile acids that encourage tumor growth in the colon. An anti-cancer diet is derived primarily from plant sources with limited high-fat animal products.
