What does the term "glycemic index" measure?

The term "glycemic index" refers specifically to how quickly foods increase blood glucose levels after they are consumed. It is a ranking system that classifies carbohydrates based on their immediate effect on blood sugar levels. Foods with a high glycemic index (GI) are rapidly digested and absorbed, leading to a swift increase in blood glucose, while those with a low GI are digested more slowly, resulting in a more gradual rise in blood sugar.

Understanding glycemic index is particularly important for managing blood sugar levels, especially for individuals with diabetes or those looking to maintain stable energy levels throughout the day. Therefore, the statement accurately reflects the role of glycemic index in nutrition, highlighting its significance in dietary choices and overall health management.
