The basic dietary requirements for patients with jaw tumors are: sufficient calories, balanced nutrition, reasonable food structure, and attention to cooking methods and eating styles. 1. Sufficient calories: Due to the high protein decomposition, decreased anabolic function and unbalanced nutrition in patients with bone cancer, the demand for protein is increasing. It should be ensured that the patients' daily intake of total calories is above 10 kJ, protein is above1.5g, and high-quality protein is the main one. 2. Balanced nutrition: According to patients' needs, the nutrients should be appropriate and complete. In addition to adequate intake of high-quality protein, it should generally be low-fat and moderate in carbohydrates. Pay attention to supplement vitamins, inorganic salts and cellulose, which can be obtained from fresh vegetables and fruits. 3. Reasonable food structure: The patient's food structure should be diverse, the pattern should be new and the structure should be reasonable. When making recipes, we should try our best to combine lightness with high nutrition and high quality, softness with digestibility with rich vitamins, freshness with cold, hot, warm and light taste of food, and total supply with cold and hot viscera of patients. 4, pay attention to cooking methods and diet: try to avoid bad stimulation such as oil smoke smell before meals. In the selection, preparation and cooking of food, we should create good sensory characteristics of food, and work hard on color, fragrance, taste and shape to suit and satisfy the tastes and habits of patients as much as possible to enhance their appetite. According to the patient's digestive ability, take a small number of meals, thick and thin collocation, liquid, soft food and hard food alternately, sweet and salty exchange and other forms of eating. In addition, in addition to diet therapy, it is suggested that patients should be treated with traditional Chinese medicine to enhance their immunity, improve their quality of life, inhibit tumor growth and prolong their lives. However, Chinese medicine treatment requires a more detailed understanding of the patient's condition before symptomatic treatment. It is recommended to go to a regular hospital for regular treatment. Now a new type of Chinese medicine has entered the clinic blindly, which is ginsenoside Rh2 (life-saving factor) extracted from ginseng, which is very effective in shrinking tumors, inhibiting the spread of cancer cells and prolonging life.
