Chemotherapy is one of the three major means of cancer treatment. About 10% of cancer patients can be cured by chemotherapy alone, and 30% of cancer patients who have received chemotherapy can be in long-term remission. Chemotherapy “does not distinguish between friend and foe”, i.e., it not only kills cancer cells, but also severely damages normal cells, especially the proliferating normal cells, and kills important organs of the human body, and also has a greater impact on important organs of the human body, such as the liver and kidney functions. Cancer patients often have serious toxic reactions during chemotherapy, such as gastrointestinal reactions, abnormal blood counts, liver and kidney functions, which bring great pain to patients and even affect the normal progress of chemotherapy. The medical experts of Beijing BeiMeiSen Oncology Pharmacy think that in addition to the necessary drug prevention, dietary treatment is a very important aspect, and the following classification lists the dietary regulation and methods of toxic reaction to chemotherapy. 1.Dietary regulation of blood image decline Chemotherapy can cause poor regeneration of bone marrow, especially the decline of white blood cells, the most obvious. In order to effectively prevent the decline of blood image, in chemotherapy patients should supplement high protein diet, such as milk, soybean, lean meat, pig’s feet, sea cucumber, fish, animal liver and red dates, peanuts, walnuts, black fungus, carrots, red beans and so on. River crabs, black fish, beef, animal boiled peptones such as donkey skin peptones (Colla Corii Asini), pig skin peptones (meat peptones), etc. also help to enhance white blood cells. Chinese medicine emphasizes the importance of replenishing the organs with the organs, so during chemotherapy you can also add animal bone marrow in moderation, such as stewed bone marrow from cows, samples, and pigs, or diets made with chicken, duck, goose, and pig’s blood. At the same time, you can also eat more five black food, such as black sesame, black rice, black beans, black dates and so on. Chinese medicine believes that “black can enter the kidney”, five black food can replenish the kidney and fill the marrow, which can help to improve the blood. 2, gastrointestinal toxicity dietary management Chemical therapy can cause oral mucositis, manifested as mucosal congestion, edema, ulceration, pain and so on. At this time, we should keep the mouth clean, brush the teeth after eating, and supplement the high nutritional fluid or office fluid diet, such as lotus seed soup, snow ear soup, milk, soybean milk, crucian carp soup and so on. Eating to avoid excessive heat, too acid and stimulating diet, acute inflammation can be oral ice fast in order to reduce inflammatory exudation, the emergence of ulcers can be used to add honey 20 ml of crushed vitamin C 0.1 grams, orally, 2 to 4 times a day. Chemotherapy damage to the gastrointestinal mucosa, nausea, vomiting, epigastric pain, nausea and so on. At this time, you can eat appetizing food, such as hawthorn, lentils, yam, white radish, mushrooms, etc., and at the same time, you should eat small meals to avoid satiety. Eating should be chewed and swallowed slowly, do not lie down for 1 hour after meal, can be scattered, do not eat water 1 hour before chemotherapy, eating such as nausea and vomiting can be taken orally 3~5 ml of fresh ginger juice. 3, dietary management and prevention of liver and kidney injury Some chemotherapeutic drugs can cause liver injury, transaminase elevation. At this time, we should eat more bitter melon, mung bean sprouts, tea, mushrooms such as shiitake mushroom, fungus, monkey head mushroom, etc., eat more vitamin-rich fruits, such as kiwifruit, peach, apple, grapes, etc., and drink more green tea, oolong tea, honey water. If the liver damage is serious, you can use 20 grams of schizandra and 20 grams of wolfberry to stew carp soup. Some chemotherapy drugs can also cause kidney injury, such as cisplatin. Clinical use of such drugs should drink more water, eat more fresh vegetables and fruits (alkaline food). Once the renal injury to limit protein intake, combined with edema to eat less salt, eat more animal kidneys, fish, spinach and red amaranth, but also can eat more water and have diuretic effect of food, such as watermelon, cucumber, winter melon, loofah.
