2274-PUB: Glycemic Index and Response of Plant-Based Nutritional Supplement and Its Subjective Satiety in Indian Adults

Abstract

Background: The major nutritional challenges faced by individuals with diabetes in South Asia is adhering to dietary advocacy and providing optimal nutrition with adequate protein and dietary fibre as they usually consume very high carbohydrate diet. This is particularly a concern in vegetarians. Aim: The objective of the study was to assess the Glycemic Index (GI) and Glycemic Response (GR) of two different flavors of a plant based nutritional supplement specially designed with high protein and fibre. The subjective satiety was also assessed. Methods: In all, fifteen overweight/obese subjects aged 18-45 years were recruited. After overnight fasting, blood samples were drawn at -5 and 0 minutes. Test and reference food providing available carbohydrates of 25g each was consumed by the participants. The capillary blood samples were drawn at 15, 30, 45, 60, 90 and 120 minutes. Participants underwent 3 days of reference food testing and 1 day of test food test in random order with 2 days of wash out period. The GI was assessed using validated ISO, 2010 protocol. Satiety index was measured using Visual Analog Scale (VAS). The dietary intake of the subjects for previous day and the test day was measured by 24-hour dietary recall. The Incremental Area Under the Curve (IAUC) was calculated using the trapezoid rule. The study was registered in the clinical trial registry of India, CTRI/2018/04/012979. Results: The GI and GR of both flavors of the supplement was categorized as low GI. The GI and GR of Flavor 1 was 27.3±4.8 and 16.4 ±2.6 (Mean ± SEM) respectively. For Flavor 2 the GI and GR was 36.7±4.4 and 25.7 ± 2.3 (Mean ± SEM). For Flavor 1, 60% of participants reported feeling hungry only after 3 hours, showing good satiety. Conclusion: The plant based high fibre high protein supplement, along with regular meal could help in reducing the postprandial glycemic response and improve satiety. Disclosure V. Mohan: None. V.
