1. Milk and yogurt: Milk contains calcium and vitamin D, which can combine with carcinogenic substances in the intestine and remove their harmful effects. Yogurt can inhibit the growth of tumor cells. 2.Honey and bee milk: honey can promote metabolism, enhance body resistance, improve hematopoietic function and tissue repair. In recent years, it has been found that bee milk contains special bee lactic acid, which is effective in preventing and treating malignant tumors. 3, tea contains catechins, can remove radioactive substances from the body. Radiotherapy patients often drink tea is beneficial to recovery. Tea can also prevent dental caries. 4, pollen food to improve intelligence, promote development, blood, increase endurance, delay aging, with hormone-like effect, enhance the ability to resist disease. 5, vegetables: fresh vegetables such as carrots, radishes, gourd fruit, eggplant, kale, etc., contain interferon inducers, which can stimulate cells to produce interferon. This substance can enhance the patient’s resistance to diseases and cancerous tumors. However, it is susceptible to destruction by heating, hence the above. It is better to eat the food raw. Many studies have confirmed that garlic has the ability to prevent and fight cancer. The fat-soluble volatile oil in garlic can activate macrophages and improve the body’s ability to fight cancer; it also contains a sulfur-containing compound that also has the effect of killing tumor cells. Onion can also fight cancer, probably due to the presence of glutathione as well as many vitamins. It has a defensive effect on lymphoma, bladder cancer, lung cancer and skin cancer. 6.Seafood: It can be used as therapeutic food for patients with malignant tumors. The active ingredients of seaweed are mainly polysaccharide substances and sodium alginate. Sodium alginate can combine with radioactive strontium and be excreted from the body. Regular consumption of seaweed and nori is beneficial to the body. The cartilage of shark can inhibit the growth of tumor, and shark fin has the ability to inhibit the infiltration of tumor into the surrounding area. Fish is rich in inorganic salts such as selenium, zinc, calcium and iodine, which are also beneficial to fight against cancer. 7.Fungal foods contain polysaccharide substances and interferon inducers, which can inhibit tumors. Shiitake mushroom is effective against stomach cancer, esophageal cancer, lung cancer and cervical cancer. Enoki mushroom also has the same effect and has tumor suppression. Monkey head mushroom is effective against stomach cancer, prolonging the survival of patients and improving immunity. Silver fungus has an inhibitory effect on cancer tumors. In recent years, it is found that 90% of B poria glycan in Poria can enhance immune function and have anti-cancer tumor effect. 8.Fruit: Almond can improve the immune function of the body and inhibit cell carcinogenesis. It has a relieving effect on symptoms such as dry mouth, but it is not suitable for patients with inflammation and ulcers in the mouth: cavity and nasal bleeding. Ume also has anti-cancer effects, and dates can inhibit the growth of tumor cells. Extracts of figs can treat stomach, throat, cervical and bladder cancers. Apples contain much pectin, which can combine with radioactive elements and promote their excretion. Papaya can stop the spread and development of cancer tumors. 9.Other: The steroid substance extracted from yams can inhibit the development of breast cancer. Corn flour can inhibit the growth of tumor and reduce the side effects of anti-cancer drugs. The polysaccharide body and coix fat in coix seeds can enhance the body’s immune function and inhibit the role of tumor cells.
