ABSTRACT: Background: Diet plays a vital role in
managing diabetes. Foods with a low glycemic index provide
lower postprandial glucose spikes and induce satiety. The objective of this
study was to assess the Glycemic index (GI) without milk and Glycemic response
(GR) with milk of two different flavours of a plant-based supplement which is high in protein and fibre,
along with a subjective assessment of
satiety. Methods: Fifteen overweight/obese subjects aged 18 - 45 years were recruited. After overnight fasting,
blood samples were drawn at 5 mins before food consumption (-5), 0, 15, 30, 45, 60, 90
and 120 minutes. Participants underwent 3 days of reference food testing and 1
day of test food in random order with 2 days of wash-out period. The GI was assessed using a validated protocol recognized by FAO/WHO, as well as
the guidelines by the International Dietary Carbohydrate Task Force for GI
Methodology. The
satiety index was measured
using the Visual Analog Scale (VAS).
The dietary intake of the subjects was measured by 24-hour dietary recall. The Incremental Area Under the
Curve (IAUC) was calculated using the trapezoid rule. Results: Both the
flavours of the supplement had low GI & GR. The GI and GR of Flavour 1 were 27.3 ± 4.8 & 16.4 ± 2.6 (Mean ± SEM)
respectively. For Flavour 2 the GI and GR were 36.7 ± 4.4 & 25.7 ± 2.3 (Mean ±
SEM). For Flavour 1, 60% and for flavour 2 66.7% of subjects reported feeling
hungry only after 3 hours, showing good satiety. Conclusion: The plant-based high fibre high protein supplement in both
flavours showed a low glycemic index and hence
may be useful to include in the diets to reduce the postprandial glycemic
response and could improve satiety.
