1, tea: someone will be mixed with tea in the feed, fed to the body with cancer cells in mice, the results found that after 3 weeks the cancer cells were inhibited and reduced. It is also reported that a substance in tea can inhibit cancer cells in various parts of the body through blood circulation. 2, bran: bran can not only assist in the treatment of diabetes, blood cholesterol, high blood lipids, constipation, obesity, dental caries and other diseases, but also to prevent the occurrence of intestinal cancer. Bran is rich in cellulose, cellulose is an insoluble fiber, can dilute a variety of carcinogenic substances in the intestinal tract, speed up the speed of food through the intestines, prompting defecation, reducing the opportunity for carcinogens and intestinal contact. 3, corn: corn can prevent hypertension, arteriosclerosis, urinary stones and other diseases, and has anti-cancer effects. The American medical community pointed out that coarse ground cornmeal contains a large number of amino acids, which have a significant effect on inhibiting cancer. In addition, the glutathione in corn, with the participation of selenium to generate glutathione oxidase, can also make chemical carcinogens inactive. 4.Sour plum: Sour plum can enhance the phagocytic ability of white blood cells, improve the immune function of the body and assist in the treatment of penile cancer and cervical cancer. 5.Soybean: Soybean contains at least 5 kinds of anti-cancer substances. One of them is similar in action to a drug that is usually used to treat estrogen-dependent breast cancer, and it has now been used in large-scale clinical trials to understand its preventive effect on breast cancer. 6, onion vegetables: these vegetables include garlic, onions, shallots, etc.. Animal experiments have shown that these vegetables can prevent cancers of the colon, stomach, lungs and liver. Some components in garlic can even interfere with the spread of cancer cells. In addition, the sulfide contained in garlic can activate the body’s immune function, thus helping to defeat cancer. 7.Green vegetables: Dark green vegetables have anti-cancer effects. Such as spinach, lettuce, etc. They are rich in antioxidants, including folic acid and lutein. Accordingly, scientists suggest that the darker the color of vegetables, the higher the antioxidant content and the stronger the anti-cancer and anti-cancer effect. 8. Shiitake mushrooms: Mushrooms are a kind of food with health benefits and anti-cancer effects, the most prominent of which is shiitake mushrooms. Because shiitake mushroom polysaccharide can enhance cellular immunity and humoral immunity, it has a similar effect of tonicity. It is said that woodcutters in the deep mountains of Czech Bohemia never suffer from colds and cancer because they often eat wild shiitake mushrooms. 9, Monkey head mushroom: Monkey head mushroom has been made into monkey mushroom tablets by Chinese pharmacy for the prevention and treatment of stomach cancer and esophageal cancer, with an effective rate of 69.3% and a significant rate of 15%. 10.Apple: Recent studies have found that the vitamin C contained in apple can hinder the generation of carcinogenic substance nitrosamine in the body, destroy the enzyme activity produced by cancer cells during proliferation, and even transform the generated cancer cells into normal cells. 11.Bee milk: According to the research reports of domestic and foreign experts in recent years, a special bee lactic acid is newly found in bee milk, which has obvious effect on cancer prevention and treatment. 12.Beef: A research group directed by microbiologist Bariza of the University of Wisconsin found that beef contains a component that can inhibit the activity of carcinogenic substances, and the component can play a role in cancer prevention. Currently, this research team is conducting in-depth research on the chemical structure and function of the new substance, which is expected to be extracted from beef to prevent cancer and anti-cancer new drugs. 13.Seaweed: Modern medical research has confirmed that seaweed foods such as kelp, nori and wakame have certain anti-cancer effects. 14, jellyfish: scientists from the jellyfish extracted from the jellyfish, with a special physiological role in antibacterial, antiviral and anti-cancer have a strong pharmacological effect. 15, the fish: modern medical research has confirmed that the silvery powdered scales of the fish contain a lot of protein, inorganic salts and oils, after acid treatment can be made guanine hydrochloride, and guanine hydrochloride is the main raw material for the synthesis of anti-cancer drugs hexathioguanine, is an effective drug for the treatment of acute leukemia and other cancers.
