What does the term "glycemic index" refer to?

The term "glycemic index" refers specifically to a ranking of carbohydrates based on their effect on blood sugar levels. This ranking indicates how quickly and significantly a particular carbohydrate food can raise blood glucose levels after being consumed. Foods with a high glycemic index are rapidly digested and absorbed, causing a swift increase in blood sugar, whereas those with a low glycemic index result in a slower, more gradual increase in blood glucose.

By understanding the glycemic index, individuals can make informed dietary choices, especially for managing energy levels and blood sugar, which is particularly important for people with diabetes or those aiming to maintain optimal health. This concept helps distinguish between different carbohydrate sources and their impact on the body, allowing for better nutritional planning.
