Patients with tuberculosis should be given food high in protein and caloric energy. Any symptoms of tuberculosis will cause serious depletion of tissue protein and caloric energy, so the supply of food protein and caloric energy should be higher than normal. The daily supply of protein is 1.5-2.0g/kg, with milk, eggs, animal offal, fish and shrimp, lean meat, soy products and other foods as sources of protein. Milk is rich in casein and calcium, which is the ideal nutritional food for TB patients. The amount of caloric energy supply is based on the principle of maintaining the patient’s normal body weight, and can be supplied at 40-50 kcal per kilogram of body weight, and carbohydrate staple foods can be supplied according to the diet without restriction, but fat should not be eaten more, mainly vegetable oil. Vitamins and inorganic salts have a great role in promoting recovery from tuberculosis. Among them, vitamin A has the role of enhancing the body’s ability to resist disease; vitamins B and C can improve the metabolic process in the body, enhance appetite, sound lung and blood vessel and other tissue functions; such as patients with recurrent hemoptysis, should also increase the supply of iron, eat more green leafy vegetables, fruits and grains, can supplement a variety of vitamins and minerals. Tuberculosis patients’ appetite is particularly bad, in order to increase appetite, you can make efforts in cooking, to achieve variety, color, aroma, taste and shape good. If possible, in addition to three meals a day, two additional snacks can be added. Should avoid eating irritating foods and pungent and phlegm-producing substances. Because tuberculosis is a chronic infectious disease, while using medicine and diet, we should also pay attention to adequate rest and appropriate outdoor activities, and pay attention to the hygiene of the environment and eating utensils.
