1, tea: some people will tea mixed in the feed, fed to the body of cancer cells in mice, the results found that 3 weeks after the cancer cells are inhibited to reduce. It is also reported that some substances in tea can inhibit cancer cells in all parts of the body through blood circulation. 2, wheat bran: bran can not only auxiliary treatment of diabetes, blood cholesterol, high blood fat, 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 carcinogens in the intestinal tract, accelerate the speed of food through the intestinal tract, prompting defecation, reducing carcinogens and intestinal contact opportunities. 3, corn: corn can prevent hypertension, atherosclerosis, urinary stones and other diseases, and anti-cancer effect. The United States medical community pointed out that the coarse grinding of cornmeal contains a large number of amino acids, a significant effect on the inhibition of cancer. In addition, corn in the glutathione, selenium participation in the generation of glutathione oxidase, can also make chemical carcinogens inactive. 4, sour plums: sour plums can enhance the phagocytosis of white blood cells, improve the body’s immune function, assist in the treatment of penile cancer, cervical cancer. 5, soybean: soybean contains at least five kinds of anti-cancer substances. One of them is similar to a drug usually used to treat estrogen-dependent breast cancer, and it has been used in large-scale clinical trials to understand its preventive effect on breast cancer. 6, onion vegetables: this type of vegetables, including garlic, onions, scallions and so on. Animal experiments have shown that these vegetables can prevent cancer of the colon, stomach, lungs and liver and other organs. 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 beat cancer. 7, green vegetables: dark green vegetables have anti-cancer effects. Such as spinach, lettuce and so on, they are rich in antioxidants, including folic acid, lutein and so on. Scientists accordingly proposed that the darker the color of vegetables, the higher the content of antioxidants, the stronger the anti-cancer and anti-cancer effects. 8, Shiitake: Mushrooms are a kind of health benefits and anti-cancer food, the most prominent of which is shiitake. Because shiitake polysaccharide can enhance cellular immunity and humoral immunity, there is a similar effect of tonic Qi. It is said that woodcutters in the mountains of Bohemia, Czech Republic, never suffered from colds and cancer because they often ate wild shiitake mushrooms. 9, monkey head mushroom: monkey head mushroom has been made by the Chinese pharmaceutical industry, monkey mushroom mushroom tablets, used for the prevention and treatment of stomach cancer, esophageal cancer, etc., the effective rate of 69.3%, the efficiency of 15%. 10.Apple: It is found in recent years that vitamin C contained in apple can impede the generation of carcinogen nitrosamine in the body, destroy a certain enzyme activity produced by the proliferation of cancer cells, and even make the generated cancer cells turn into normal cells. 11.Bee milk: According to the research reports of domestic and foreign experts in recent years, in the bee milk, a special kind of bee lactic acid has been newly discovered, which has obvious effect of preventing and controlling cancer. 12, beef: the United States of America, the University of Wisconsin microbiologist Barry Za guided the research team found that beef contains a can inhibit the activity of carcinogenic substances, the ingredients can play a role in cancer prevention. At present, this research group on the chemical structure and function of the new substances are undergoing in-depth study, it is expected to be extracted from beef cancer prevention and anti-cancer new drugs. 13, seaweed: modern medical research has confirmed that kelp, seaweed and wakame and other seaweed foods have a certain anti-cancer effect. Research has found that the blood of cancer patients is acidic, and kelp contains high calcium, can regulate and balance the pH of the blood, play a role in cancer prevention; at the same time, it contains fiber yarn is not easy to be digested, eaten to increase the amount of stool, promote the excretion of certain carcinogens in the intestines, which can help the human body cancer prevention and health care. 14, jellyfish: scientists extracted from jellyfish jellyfish, has a special physiological role in antibacterial, antiviral and anticancer have a strong pharmacological effect. 15, scallop: modern medical research has confirmed that the scallop silver powdery fine scales contain a large number of proteins, inorganic salts and oils, acid treatment can be made after guanine hydrochloride, and guanine hydrochloride is the synthesis of anticancer drugs six thioguanine the main raw material for the treatment of acute leukemia and other cancers of the effective drugs.
