RESUMO
There are specific formulas of enteral nutrition to improve glycemic control in diabetic patients containing different types of carbohydrates which glycemic response should be investigated. The consumption effect of a formula with carbohydrates with extended release was determined on the glycemic response and postprandial insulin in 21 healthy individuals (11 men and 10 women) from 17 to 25 years old, who consumed in two different time the polymeric enteral formula for diabetics and the reference food (white bread) in a quantity of 50 g of available carbohydrates. The glycemia was measured at 0, 15, 30, 45, 60, 75, 90, 105 and 120 min and the insulin concentrations in fasting and within 120 min. The area in the glycemic curve was measured being the lowest the formula 11718.20. ± 1112.38 than in white bread 13269.18 ± 1351.05 (P<0.001). The glycemic index (GI) resulted to be intermediate (63.33±5.22) and lower when compared to the GT ranks published for the reference food (80-96). A lower concentration of glycemia occurred after the consumption of the formula, without increments in the insulin requirements; thus, assuming an adequate use in diabetic and a more extended feeling of fullness. This effect and the glycated hemoglobin should be studied after the extended consumption in people with diabetes.
