1. Dietary principles The question of cancer patients regarding life and diet is: “What do I need to pay attention to?” The general answer is: a light diet and appropriate exercise while ensuring adequate nutrition supply. Cancer patients, especially those with breast cancer, often go further and ask, “I heard from Chinese medicine practitioners that I cannot eat chicken, beef, or lamb with this disease, do you think I can eat them?” In fact, not only chicken, beef and mutton, but also snapper, duck, eggs, fish, seafood and even pumpkin and chili. The list can be long, and these types of foods that need to be “avoided” can be collectively referred to as “hairy”. Of course, it is not very meaningful to over-discuss the taboos of dietary issues. However, studies have proven that one of the causes of female breast cancer is related to estrogen, and the raw materials that make up these hormones are related to cholesterol, just like lung cancer is related to smoking, but not the only cause, as the actual lungs are closely related to the catabolism of fats, and excessive high fat intake increases the burden on the lungs, which are more sensitive to the toxic effects of smoke and pollution. All again, excessive high-fat diet is to be avoided for breast cancer and other tumor patients. The amount of fat intake will not have a major impact on the body if it is followed with reasonable nutrition. The actual explanation of high estrogen level and smoking leading to high incidence of lung cancer is only relative and not sufficient to clarify the real cause of the disease. I have never advocated that you should eat more of a certain food after surgery and radiotherapy. The principle of diet is to follow a fundamental rule, just eat when hungry, diet is to meet nutritional needs, hunger and the need for diet body and mind tend to send signals both to want to eat such things to repair tissues and cells, this signal is not appetite and greed, research proves that in the former diet after good absorption, appetite and greed over-emphasis on eating more or a certain food will aggravate the body burden. Under normal circumstances, as long as you feel comfortable after eating, you can continue to eat. If you avoid eating or favor too much food, but aggravate the nutritional or metabolic deficiencies. As for foods that are hot or cold and nutritious, they are naturally more ideal for breast cancer patients. In my experience, breast cancer patients should eat less milk and large meat products. 2. Eat regularly and quantitatively. Don’t overeat or overeat partially, but take in nutrition and calories in a planned way. Low fat, low cholesterol, high quality protein diet, such as lean meat, eggs, yogurt, less salt cured, smoked, baked, baked and caramelized food. Eat coarse grains, such as corn, beans and other grains. A diet high in fiber is good for breast cancer patients. Vegetables and fruits rich in vitamin A and C, such as apples, fresh kiwi, carrots, etc. Foods that inhibit cancer cells such as cabbage, mustard, mushrooms, etc.; dried fruits such as sesame, pumpkin seeds, peanuts, etc. are rich in many vitamins and trace elements, fiber, protein and unsaturated fatty acids. Meals are the mainstay, supplemented by supplements. Take reasonable food supplements to improve immunity. Do not eat spicy and stimulating food, quit smoking and alcohol, and forbid the consumption of moldy and spoiled food. Pay special attention to drinking water and keep the stool smooth. Constipation will make chemotherapy drugs accumulate in the body and aggravate the toxic reaction. 3, according to the body eating “Su Wen Wu Chang Zheng Da Lun” refers to “grain and rain fruits and vegetables, food nourishment exhausted, do not make too much, hurt its right.” The “Thousand Gold Recipe for Food” says: “Food can drain the evil and calm the internal organs, refresh the mind, and give blood and energy”, which clarifies the relationship between disease and diet. Postoperative patients with breast cancer need to regulate their diet to nourish their vital energy and take appropriate medicinal meals, so they should be given products to nourish the vital energy and blood, essence meat soup, to strengthen the spleen and nourish the kidney. Patients with heavy qi deficiency can enter ginseng and astragalus, cinnamon soup, shiitake mushroom, fungus and silver fungus to improve the immune function of the body. Seafood has the effect of anti-cancer and dispersion, so you can eat more jellyfish, kelp, seaweed, sea rice, etc. High-fat foods are not suitable and should be eaten as little as possible. Spicy food should be eaten sparingly. At the same time, the diet should be properly adjusted according to the changes of the four seasons, for example, in winter, we can eat warm, ginger, cinnamon, onion and garlic, ginger, etc. In summer, we can give more mung bean soup or watermelon juice to replenish the consumption of body fluids, and in autumn, we should eat silver fungus and dendrobium. It is important to emphasize the dialectical administration of food according to the yin and yang of the body’s deficiency, cold and heat. During chemotherapy, there are often bone marrow suppression and gastrointestinal reactions, etc. Reasonable dietary care can not only improve the taste and nutrition, but also strengthen the body and improve immunity. Gastrointestinal reactions are one of the most common adverse effects of chemotherapy. When the body occurs gastrointestinal discomfort, vomiting, anorexia, diarrhea, constipation, etc. will cause disruption of the internal environment, resulting in a series of damage. The appropriate dietary structure adjustment can promote the digestion and absorption of food, reduce the adverse stimulation of gastric mucosa and reduce the burden on the gastrointestinal tract. It minimizes the gastrointestinal reactions caused by chemotherapy, obtains necessary nutrients, enhances the tolerance as well as resistance of the body, reduces discomfort and improves the quality of life during chemotherapy. Nausea and vomiting directly inhibit the digestive function and make the patient’s appetite diminish. At this time, it is not necessary to eat at the right time, but to eat less and more meals and give a light liquid or semi-liquid diet, such as thin rice, clear soup, steamed eggs, etc., so as to make efforts to diversify food, which is delicious, colorful and fragrant, and play a role in promoting appetite. Chemotherapy drugs not only have a strong killing effect on tumor cells, but also on the proliferating bone marrow cells, so there will be a drop of white blood cells in the blood after chemotherapy, and the ability to resist infection is weakened. The decline in white blood cells is generally temporary, and Western medicine believes that as long as the patient’s bone marrow cells have normal hematopoietic function and strengthen nutrition, the patient will generally begin to recover 3 weeks after chemotherapy. However, the hematopoietic function of bone marrow cells can be restored better through reasonable dietary regimen and appropriate Chinese medicine dialectical treatment. There are cold, hot, deficient and real body types, and there are also cold, hot, warm and cold foods and medicines. Cold diseases are treated with warm food, while hot diseases are treated with cold products. The bias of food is used to correct the bias of disease and achieve the purpose of treatment. For example, the spleen and stomach deficiency cold symptoms, manifested as a light mouth tasteless, sometimes vomit clear saliva, like warm, fear of cold, mental discomfort, physical incompetence, should choose warm food to help Yang, such as dates, cinnamon, dry ginger, or by cooking concentrated products, do not cold food. For example, if the symptoms of Yin deficiency and internal heat are clinically seen in cancer combined with bacterial infection or after receiving radiotherapy or chemotherapy, manifesting dry mouth, red tongue or no moss, constipation, short red urine, irritability, etc., the diet should be chosen to nourish Yin, generate fluid, clear heat and cool blood, such as rice and millet porridge, mung beans, bitter melon, white radish, raw lotus root, kiwi, silver ear, etc., and avoid hot foods. Another example is that the heat evil burning lung yin syndrome caused by radiotherapy, manifested as coughing chest pain, dry cough without sputum, or sputum with blood, coughing blood, chest tightness and shortness of breath, red tongue with flowery peeling or less moss, it is appropriate to eat sweet and cool nourishing products, such as loquat fruit, white pear, umeboshi, lotus root, banana, etc. In the recovery period recipes often with some anti-cancer, anti-cancer food, such as konjac, celery, cauliflower, sweet potato, foraged vegetables, mushrooms, fungus, kelp, cabbage. Supplement the diet with anti-cancer and anti-cancer fruits, such as kiwi, banana, apple, sugar cane and strawberry. Add vitamin-rich and high-fiber foods such as soybeans, corn, mung beans, brown rice and bran to your diet as much as possible. Eat less food with food additives and food containing pesticides, such as bean sprouts, artificially raised chickens, ducks and fish. Silver fungus jujube yam soup or coix rice lotus seed porridge, to benefit the spleen and nourish the body. 4. Chinese medicine dialectical treatment After surgery plus chemotherapy patients mostly have qi deficiency, after radiotherapy mostly cause yin injury, according to different types of evidence dialectical application of Chinese medicine. 5. Comprehensive treatment Psychological strengthening training and suitable physical exercise are very important links. It is proved that if the life after surgery, radiotherapy and chemotherapy is well adjusted, everything can be completely restored to normal without affecting physiology, life and life expectancy.
