<prompt> Among the following food items, which one has the highest Glycemic Index?Corn flakesBrown riceIce-creamWhole wheat bread  <response>: The increase in blood glucose after a test dose of a carbohydrate compared with that after an equivalent amount of glucose is known as the glycemic index. Glycemic Index decreasing order: Corn flakes whole wheat breadBrown riceIce cream Most varieties of legumes, pasta, fruits, and dairy products are low-GI foods 55 or less on the glucose reference scale. Breads, breakfast cereals, rice, and snack products, including whole-grain versions, are available in both high- 70 or greater and low-GI forms. Glucose and galactose have an index of 1 or 100, as do lactose, maltose, isomaltose, and trehalose, which give rise to these monosaccharides on hydrolysis. Fructose and the sugar alcohols are absorbed less rapidly and have a lower glycemic index, as does sucrose. The glycemic index of starch varies between near 1 or 100 and near 0 as a result of variable rates of hydrolysis, and that of non-starch polysaccharides is 0. Foods that have a low glycemic index are considered to be more beneficial since they cause less fluctuation in insulin secretion.
