Which statement best defines glycemic index?

Explanation:
Glycemic index shows how fast the carbohydrates in a food raise blood glucose after you eat, using a standard reference food set at a value of 100. A high GI means a quick, larger spike in blood glucose, while a low GI means a slower, more gradual rise. This measure applies specifically to carbohydrate-containing foods, not vitamins, fats, or protein quality. Using GI helps you choose foods that promote steadier energy and better blood sugar control.
