According to the American Diabetes Association, is important to focus on glycemic control in order to prevent microvascular complications in patients with type 1 diabetes, and the adoption of a plan healthy food is crucial in treating these patients. The method of carbohydrate counting is a nutritional strategy, it is a method used by diabetic individuals, which combines the total carbohydrate intake at meals with the dose of insulin used, with the goal of maintaining blood glucose within the limits appropriate. The aim of this study was to assess whether the nutrition intervention, using the method of carbohydrate couting, influences the glycemic control of patients with diabetes mellitus type 1 (DM1). We evaluated 157 DM1, 96 constituted the intervention group with diet and the use of the method of carbohydrate counting and 61 DM1 patients formed the control group with diet and without the method of carbohydrate counting. The patients were monitored for six months. In the first visit were submitted to a questionnaire, anthropometric, biochemical, clinical and dietary evaluations. Significant difference between the food record completed for 3 days and prescribed diet, in grams of protein consumed per day 50.39 + 29.27 and 22.01 + 3.05 (p = 0.02), on the glycemic index (GI) of lunch 43.00 + 24.89 and 7.83 + 1.88 (p = 0.02), and dinner 50.09 + 35.09 and 7.56 + 2.57 (p = 0.00). For anthropometric assessment increase was not significant in both groups, the body mass index and anthropometric parameters (waist circumference, hip circumference and the waist-hip ratio). In the assessment of biochemical parameters, there is a significant decrease, only in the intervention group, the glycated hemoglobin (A1C) from 9.8 + 2.26 to 9,1 + 2.16 (p = 0.023) after 6 months. The correlations between the anthropometric data and A1C, and between different types of fatty acids in the diet proposal and biochemical parameters cholesterol, triglycerides, HDLc and LDLc plasma were of low intensity. The results concluded that intervention by the method of carbohydrate counting has provided a significant improvement in glycemic control of patients.
