The best food for tuberculosis patients can be divided into three categories: 1, nutrient-rich calorie food or calorie-concentrated food; 2, food rich in vitamin A, vitamin C and vitamin E; 3, protein-rich food. Nutritional calorie-rich foods or calorie-concentrated foods can provide TB patients with the energy needed for metabolism, meet the growing metabolic needs of TB patients during the course of the disease, and at the same time can effectively slow down the phenomenon of sudden weight loss, such as bananas, cereal porridge, peanuts, wheat and other foods. Foods rich in vitamin A, vitamin C and vitamin E, such as oranges, mangoes, tomatoes, nuts and other fruits and vegetables, vitamins can release energy for the body to use, while helping to build up proteins and cells, which will help the patient to recover from the disease. Protein-rich foods are effective in relieving the loss of appetite experienced by TB patients. Foods such as eggs, cheese and soy are rich in protein, which provides the energy and essential nutrients needed by the body for daily metabolism.
