Abstract: Glycemic index (GI) describes the blood glucose response after consumption of a carbohydrate containing test food relative to a carbohydrate containing reference food, typically glucose or white bread. GI was originally designed for people with diabetes as a guide to food selection, and advice being given to select foods with a low GI. Nonetheless low GI food should not be limited to diabetes patients but healthy individuals too as more recent recommendations on the potential of low GI diets to reduce the risk of chronic diseases and to treat other metabolic syndromes. This study aims to evaluate the GI of 2 oral nutritional supplements, Metabolic Recovery and Metabolic Relievve in healthy adults. Fasted subjects consumed one of the 2 oral nutritional supplements at each visit, with a two day wash out period between visits. Every subject received both oral nutritional supplements and blood glucose at 0, 15, 30, 45, 60, 90 and 120 mins were measured after the consumption of oral nutritional supplements which all containing 50g carbohydrates per serving. The trapezium method was used to compute the area under the curve for blood glucose and GI of both oral nutritional supplements were determined with reference to glucolin. The results show that both oral nutritional supplements has low GI, with Metabolic Recovery having the GI of 46.7 ± 16.4 and Metabolic Relievve with GI of 45.2 ± 16.4. Therefore, both Metabolic Recovery and Metabolic Relievve can be the preferred option for nutritional management of diabetic patients and healthy individuals in need of nutritional support.
