Importancia da orienta？？o nutricional e do teor de fibras da dieta no controle glicêmico de pacientes diabéticos tipo 2 sob interven？？o educacional intensiva

objective: to evaluate the importance of nutritional counseling within a set of multidisciplinary interventions. subjects and methods: forty-seven patients with type 2 diabetes and hyperglycemia (a1c > 8%), treated conventionally (n = 19, gc) or intensively in six weekly visits (n = 28, gi) were analyzed. we evaluated mean weekly blood glucose (mwg) at baseline and after 6 weeks in both groups. results: gi reduced caloric (p = 0.001), carbohydrate (p = 0.004), and fat (p = 0.001) intake, and increased fiber consumption, while gc reduced fiber intake (p = 0.018). glycemic control (mwg < 150 mg/dl) occurred in 75% of gi patients and in 31.6% of cg patients (p = 0.003), with negative correlation between changes in fiber intake and mwg values (r =-0.309; p = 0.035). results were maintained after 12 weeks. conclusion: educational short-term intensive intervention was more effective than conventional treatment to achieve glycemic control. our results also indicate that a more appropriate fiber content in the diet contributes for better blood glucose control in these patients.
