Objective - To evaluate the effect of diet therapy with the inclusion of specialized food product with a modified carbohydrate profile (fruit jelly) on glycemic and metabolic parameters in patients with type 2 diabetes mellitus. The study included 45 patients (aged 35 to 69 years) with type 2 diabetes with concomitant obesity I-III degree. The study was conducted in two stages. The first phase evaluated the effect of jelly intake on postprandial glycemia with determination of blood glucose levels on an empty stomach and 30, 60, 120 and 180 minutes after consumption of fruit jelly with maltitol, pectin and sublimated raspberry juice and traditional marmalade with fructose (control), containing 25 g of digestible carbohydrates. In the second phase the effectiveness of combination therapy during 2 weeks of the inclusion of fruit jelly with a modified carbohydrate profile in a standard hypocaloric diet (1550 kcal/day) has been assessed. It has been shown that the dynamics of postprandial glycemia in patients with type 2 diabetes after the consumption of fruit jelly with a modified carbohydrate profile was comparable to the dynamics of blood glucose after eating traditional marmalade with fructose. Inclusion of fruit jelly with a modified carbohydrate profile in the standard diet therapy of patients with type 2 diabetes during 2 weeks was accompanied by positive dynamics of carbohydrate and lipid metabolism, as well as a decrease in the content of lipid peroxidation products in blood plasma: reducing the level of conjugated dienes and malondialdehyde averaged 15.2 and 17.4% from baseline (p<0.05), respectively, while content of lipid peroxidation products in blood plasma did not changed in patients from the control group.
