What does the glycemic index measure?

The glycemic index is a ranking system for carbohydrates based on their immediate effect on blood sugar levels after consuming them. Foods with a high glycemic index cause a rapid increase in blood glucose levels, while those with a low glycemic index result in a slower, more gradual rise. This measurement is particularly important for individuals managing conditions such as diabetes, as it helps to inform choices that can lead to better blood sugar control.

Understanding the glycemic index aids in selecting foods that stabilize blood sugar levels, making it a critical concept in nutrition and dietary planning. The focus on how quickly foods raise blood glucose levels is essential for promoting overall health and managing energy levels effectively throughout the day.
