Many family members of glioma patients do not know how they should take care of them after treatment, thinking that they should not eat this or that, thus severely avoiding food for the patients. In fact, this is not correct. Avoidance of food should be decided according to the disease nature and the individual characteristics of different patients, we do not advocate too much avoidance of food. Most patients need to restrict or taboo foods such as high-temperature frying, smoking and barbecue, spicy stimulation, greasy and hard. The saying “you can’t eat hairy food, only alkaline food, etc.” lacks scientific basis and should not be listened to or believed. Food taboos should be decided according to the condition and individual characteristics of different patients. Patients in the early post-operative period should not over-emphasize nutrition and large supplements during the acute period, and then take supplements after the digestive function has basically returned to normal. The patient should pay attention to the long-term slow tonic, choose the seasonal tonic, depending on the person. The glioma patients should do the following in their usual diet: 1. Pay attention to the dietary balance Dietary balance is the basis for maintaining the body’s balance. A well-balanced diet is the best source of nutrients for the body. For patients with severe malnutrition, it is recommended that individualized nutritional treatment should be carried out by a professional clinical dietitian after assessing the overall condition of the patient. 2.Ensure food diversification and rationalization To ensure the intake of balanced and comprehensive nutrition, daily food diversification is necessary, that is, according to the proportion of the five major food groups shown in the Chinese population’s balanced diet pagoda. Cereals, vegetables and fruits, fish, poultry, meat and eggs, dairy and soy and nut foods are diversified and reasonably matched. 3.Small and multiple meals, eating light and easily digestible food For patients after radiotherapy and surgery, due to weakened digestive function, increasing the number of meals can achieve the purpose of reducing the burden on the digestive tract while increasing food intake.
