Elements of cancer prevention and reasonable diet First, don’t smoke or quit smoking as early as possible. In the United States, 90% of lung cancers are directly caused by smoking, and another 3% are caused by inhaling second-hand smoke. Half of the people who smoke will die from smoking-related diseases, many of which are malignant tumors. Second, develop good eating habits. It is recommended that people should eat at least five different kinds of vegetables and fruits every day, which is an effective way to help fight cancer. People who rarely eat fruits and vegetables are much more likely to develop cancer than those who eat more fruits and vegetables. Secondly, don’t eat pickled food or repeatedly heated food. Pickled or long-lasting food is prone to nitrite, which is a strong carcinogenic substance. Thirdly, proper aerobic exercise is the recommended exercise method by scientists. According to research, an hour of walking every day can reduce the possibility of colon cancer by 46%. Fourth, know the family medical history. Many cancers are associated with family history, such as breast cancer, liver cancer and gastrointestinal tumors. Many cancer patients are treated while their accompanying family members are also found to have tumors during physical examinations. The reason may be that the family has the same or similar dietary habits, and secondly, from the genetic point of view, the oncogenes in the genes of patients and family members are susceptible to activation or inactivation of oncogenes by similar external factors, thus causing the occurrence of tumors. Therefore, if you have family members who have suffered from malignant tumors (parents, siblings, children), then you may need to have a medical checkup at a relatively young age. Foods to prevent cancer 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 is 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 in the body. Radiotherapy patients often drink tea is beneficial to recovery. Tea can also prevent dental caries. 4, pollen food effect is 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 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 then 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 selenium, zinc, calcium, iodine and other inorganic salts, 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.Fruits Almond can improve the immune function of the body and inhibit cell carcinoma. 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 tumor cells. Prevent cancer and how to eat (1) Diversify food: A wide range of recipes can not only meet the various nutrients required by the body, but also inhibit harmful carcinogenic substances. (2) Drinking alcoholic beverages must be in moderation: drinking more alcohol is detrimental to health. Cancers of the mouth, throat, esophagus and liver are related to excessive drinking. Those who drink a lot of alcohol and smoke at the same time have a greater risk of developing cancer. (3) Avoid excessive cholesterol intake: A low-fat diet can reduce the risk of breast, prostate, colon and rectal cancers. (4) Consume foods that contain enough starch and fiber: You should eat more fruits, vegetables, dried beans, whole grains, legumes and their products. to increase the intake of starch and fiber, which can reduce colon and rectal cancer. (5) Maintain a balanced nutrition and ideal body weight. Avoid eating too much sugar.
