During chemotherapy, it is recommended to eat soft, easily digestible and light foods. Try to avoid spicy and sour, irritating or too cold and too hot food. Because chemotherapy drugs can damage the mucosa of the digestive tract, causing necrosis of the epithelial cells of the digestive tract and the formation of potential ulcers on the surface of the digestive tract. Therefore when eating some greasy, sour, spicy or hard food, it will aggravate the burden of the digestive tract. Symptoms such as intermittent diarrhea, abdominal pain, nausea and vomiting occur. Therefore, during chemotherapy, you can eat some noodle soup, egg custard, vegetables and other foods to supplement protein and vitamins, but also to minimize the damage of food to the digestive tract.
