Brief Summary
Modification(s)  
Research studies have shown that lifestyle, in particular dietary aspects play an important role in
preventing / increasing the burden of the chronic diseases. Dietary habits could therefore be
modified to exert a positive impact in the prevention and treatment. It has been suggested that the
high glycemic carbohydrate foods – those foods containing carbohydrates which elicit rapid blood
glucose rise and thereby increase the insulin demand leading to hyperinsulinemia, insulin
resistance and type 2 diabetes. Hence, there is a need to understand the blood glucose raising
potential of foods in India to be of an important tool to aid in the prevention and or management of
diabetes and its complication. Thus evolved the concept of ‘Glycemic Index’ (GI) which ranks the
foods, based on the speed at which the food raises the blood glucose in a scale of 0 to 100, 100
indicating high glycemic index corresponds to oral glucose’s GI. Today, India leading the world with
the largest number of diabetic volunteers causing a heavy economic burden to the country urgently
need to look at cost effective strategies to combat this situation. A cost effective dietary approach
like estimating and understanding the role of glycemic index of various Indian foods in the lifestyle
related diseases like diabetes is urgently needed. Capillary blood glucose will be measured at 0, 15,
30, 45, 60, 90 and 120 min using Hemocue Glucose 201+ analyzer (Hemocue®Ltd, Angelholm,
Sweden). Standard glucose drink will be given for 3 different days to get average glucose response
and each test food for 1 day with a wash out period of 2 to 3 days between each test day. The GI
was calculated as IAUC of test food/IAUC of reference (Glucose) food x 100.
