Once a tumor patient is on chemotherapy drugs, his body will be extremely weak. In this case, he often has weakness, loss of appetite, nausea and vomiting. Chemotherapy patients usually choose light food. While choosing light food, because tumor patients are weak, they should actively supplement nutrition. It is recommended to supplement protein first, and add electrolytes, such as salt and potassium. A variety of flavors repeatedly stimulate patients’ appetite and taste sensation, so that appetite can be better maintained and facilitate the later chemotherapy. At the same time, it is recommended to drink more soups in the diet, including carp soup, pigeon soup and so on. It can replenish the patient’s energy without adding too much burden to the stomach and intestines.
