Determination of glycemic index of enteral formulas used in clinical practice

摘要

Glycemic Index (GI) is a measure of carbohydrate quality and is recognised as a valid and reproducible method of classifying carbohydrate foods according to its effects on postprandial glycaemia. In this randomised crossover trial (RBR-7rjx3k) we determined the GI of nine enteral formulas, following the Food and Agriculture Organisation/World Health Organisation method. Forty healthy participants were included in the study (85% female mean age 27.1 +/- 6.7 years). GI of the enteral formulas ranged from 40.5 to 85.2; four formulas had high GI (Nutrienteral 1.5 (R), Novasource GI Control (R), Diamax (R), Isosource Soya (R)), two intermediate GI (Fresubin 1.2 HP Fibre (R), Nutrison Energy Multifiber 1.5 (R)) and three low GI (Trophic 1.5 (R), Glucerna (R), Novasource GC HP (R)). The GI coefficient of variation ranged from 22.9% to 83.6%. The effect of the enteral formulas with low GI in glycemic control of patients with enteral nutrition prescription needs to be test in future studies.
