Breast cancer patients usually suffer from blood loss, post-operative loss of appetite, decreased digestive and absorption functions, and poor stool, resulting in malnutrition, which affects the recovery of the body after surgery, and reasonable regulation of post-operative breast cancer diet is important for the recovery of the disease. What to eat after breast cancer surgery? The diet after breast cancer surgery should pay attention to balanced diet, diversification, no partial food, no taboo food, meat and vegetable, coarse and fine food. Patients who have to undergo radiotherapy and chemotherapy after surgery are generally advised to eat cool food and cold drinks; however, patients who have cold sensation are advised to eat hot food. 1, due to the postoperative nausea and vomiting directly inhibit the digestive function of patients to reduce appetite, at this time do not need to force patients to eat more, can eat less and more meals, give light liquid or semi-liquid diet, such as thin rice, clear soup, steamed eggs, etc., and strive to achieve food diversity. 2, eat more vitamin-rich food, such as fresh vegetables, fruits, sesame oil, cereals, beans and animal offal. Among them, vitamin A and vitamin C have the effect of stopping the spread of cellular malignancy and stabilizing epithelial cells. Vitamin C can also prevent the common symptoms of radiation damage to a certain extent and make the level of white blood cells rise with relief; vitamin E can promote cell division and delay cell aging; vitamin B1 can promote patients’ appetite and reduce the symptoms caused by radiation treatment. 3.After breast cancer surgery, you should eat more foods with anti-cancer effects. Common anti-breast cancer foods include soy, radish, date, tomato, sweet potato, garlic, onion, cabbage, etc. 4. Breast cancer patients should eat some sugars to replenish the body’s heat after surgery, because the sugar in the patient’s body will be destroyed after chemotherapy, so that the sugar element will drop rapidly and the lactic acid in the blood will increase, which is unfavorable to the post-operative patients, so it should be moderately supplemented. 5. The post-operative diet of breast cancer should include easily digestible protein foods, such as fish, eggs, milk and soy products, among which milk and eggs can improve the protein disorder after radiotherapy. This can effectively improve the anti-cancer ability of the patient’s body. Breast cancer patients’ appetite will be greatly reduced after surgery, so the diet of patients should be diversified and pay attention to the color, aroma, taste and shape to promote patients’ appetite, but avoid eating foods that are difficult to digest, and no more drinking and smoking. Breast cancer patients should not eat raw onion and garlic, pork, pumpkin, alcoholic wine and other foods that are warm, fried, greasy, fishy, thick, stale, moldy, etc., which help fire and produce phlegm and hinder spleen transportation after surgery. In addition, excessive nutrition and obesity have a negative impact on the treatment of breast cancer. In the long-term life of breast cancer patients after treatment, they should adhere to the principle of diet in moderation but not in excess, while ensuring the nutritional needs. In the dietary arrangement, the total daily intake of calories, fats and sugars should be well known, and binge eating and drinking should be avoided. Can I eat shrimp and crab seafood after breast cancer surgery? Avoidance of food is a common problem for most cancer patients. In particular, there are some statements such as “you cannot eat chicken” and “you can eat crab”, which lead patients and their family members to be overwhelmed. Seafood mainly includes fish, shrimp, crab, shellfish and kelp, seaweed and other algae, which are rich in high-quality protein, minerals and vitamins, tasty and nutritious. However, because of its special smell, it belongs to the traditional meat and fishy food, often called “hair”, so some patients with breast enlargement and breast cancer dare not eat it because they believe that eating it will cause the recurrence of old diseases and aggravation of new ones. In fact, this is a misconception. The term “hairy food” is not found in the general Chinese medicine books, but it is mostly food that can cause allergic reactions, so as long as you are not allergic to it, you can eat it safely. Fish contains a kind of unsaturated fatty acid that can effectively inhibit the growth and proliferation of cancer cells, which can help to prevent breast cancer. Kelp contains a large amount of iodine, which can promote the reduction of estrogen levels, restore the normal function of the ovaries, correct endocrine disorders, eliminate the hidden danger of breast enlargement, and also have a certain therapeutic effect on mastopathy.
