The importance of nutrition therapy in treating diabetes mellitus has been emphasized since it was first identified, being the only effective intervention then. In Type 1 diabetes, its importance is even more pronounced due to its association with the use of exogenous insulin. Appropriate caloric ingestion in order to attain normal body weight maintains anabolism, warranting growth and development and decreases insulin resistance. The correct use of micronutrients and macronutrients is vitally important. The knowledge of carbohydrate metabolism and its association with glycemic elevation, in qualitative and quantitative aspects, is emphasized since it enables good control, especially during the postprandial period. The correct use of proteins to prevent or treat nephropathies and lipids or to avoid dyslipidemia, obesity, and cardiovascular disease are also addressed. Sucrose and artificial sweeteners should be used with care. Compliance with treatment, however, is the key to reach the desired goals.
