GRAPE • Glycemic Response of Amylopectin Containing Drinks

Overview

To quantify the glycemic index of the SP energy-smart-based nutrition supplement and the SP Glucose-support formula as compared to a glucose drink. We hypothesized that both the energy-smart-based nutritional supplement and the SP Glucose-support formula will have low glycemic index. The aim of the study is to quantify the glycemic index of the SP energy-smart-based nutrition supplement and the SP Glucose-support formula as compared to a glucose drink. We hypothesized that both the energy-smart-based nutritional supplement and the SP Glucose-support formula will have low glycemic index.

Subjects: 9 non-diabetic (HbA1c \< 6.5) males aged 30-55 years with body mass indices ranging from 27.5 to 35 kg∙m-2. Individuals with impaired glucose tolerance will be included as long as they are not diagnosed with diabetes and their HbA1c is less than 6.5. Preliminary Testing: Medical history, weight, height, body composition via dual x-ray absorptiometry (DXA) and glycosylated hemoglobin (HbA1c) measurement. Protocol: After a 10-hour overnight fast, subjects will complete 3 experimental visits in which they will ingest one of three beverages in a randomized order. During experimental visits subjects will either be given the following 3 experimental drinks: * Full SP-glucose balance formula (200 kcal) * Energy smart carbohydrate blend (50 g, 200 kcal) * Liquid dextrose solution in the form of TRUTOL ® Glucose Tolerance Test Beverage (50 g, 200 kcal)
