Brief Summary: 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 â€˜Glycemic Indexâ€™ (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 glucoseâ€™s GI. Today, India leading the world with the largest number of adults with diabetes causing a heavy economic burden to the country urgently needs 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.

**Aim:** To measure glycemic index (GI) of boiled potato.
