What does the term "Glycemic Index" refer to?

The term "Glycemic Index" refers specifically to a measure of how quickly carbohydrate-containing foods raise blood glucose levels after consumption. Foods are ranked based on this effect, with higher glycemic index values indicating a more rapid increase in blood sugar. This is particularly important for individuals managing diabetes or those interested in maintaining stable energy levels.

Understanding the glycemic index helps in making informed dietary choices, as foods with a low glycemic index tend to promote better blood sugar control and can enhance satiety and overall health. In contrast, the other options do not accurately define the glycemic index: It does not pertain to food portion size, protein content, or a general ranking of foods based on healthiness.
