In patients with diabetes combined with tuberculosis, diet-assisted treatment is very important, as follows: 1. Sugar intake: Carbohydrates are the main food that provides calories. Sugar is more strictly controlled in diabetes, but tuberculosis requires sugar intake to provide sufficient calories to help treat tuberculosis. Therefore, sugar intake should be moderate. Patients’ blood sugar should be controlled at fasting blood sugar 6-7mmol/L and postprandial blood sugar <10mmol/L. It is best to avoid monosaccharide or disaccharide foods, such as cookies, chocolate and ice cream and other pastries, and it is best to choose multi-sugar foods, such as buckwheat, oats and other miscellaneous foods; 2. Protein intake: improve protein intake, such as beef, chicken and fish; 3. Fat intake: try to avoid animal fat diet Choose more vegetable fats; 4, more intake of vitamin B, etc.
