Question

Ingestion of a food with a high glycemic index will result in which of the following as the first reaction Hyperglycemia with increased insulin secretion Hypoglycemia with increased insulin secretion Hyperglycemia with decreased insulin secretion Hypoglycemia with decreased insulin secretion

Answer 1

The glycemic index (GI) is a measure of the blood glucose-raising potential of the carbohydrate content of a food compared to a reference food (generally pure glucose). Carbohydrate-containing foods can be classified as high- (≥70), moderate- (56-69), or low-GI (≤55) relative to pure glucose (GI=100).

The consumption of high-GI foods results in higher and more rapid increases in blood glucose concentrations than the consumption of low-GI foods. Rapid increases in blood glucose (resulting in hyperglycemia) are potent signals to the β-cells of the pancreas to increase insulin secretion. Over the next few hours, the increase in blood insulin concentration (hyperinsulinemia) induced by the consumption of high-GI foods may cause a sharp decrease in the concentration of glucose in blood (resulting in hypoglycemia).

Hence, first option i.e, Hyperglycemia with increased insulin secretion is the correct answer.
