Which tool estimates how quickly and how high a food raises blood glucose?

The glycemic index is a valuable tool used to estimate how quickly and how high a particular food raises blood glucose levels. It ranks carbohydrates on a scale from 0 to 100 based on how they affect blood sugar levels after consumption. Foods with a high glycemic index are rapidly digested and absorbed, leading to swift spikes in blood glucose. In contrast, foods with a low glycemic index release glucose more slowly and steadily, contributing to more stable blood sugar levels.

This distinction is important for those managing blood sugar, including individuals with diabetes, as well as for athletes looking to optimize performance and recovery through dietary choices. Understanding the glycemic index enables individuals to select foods that better support their energy needs while maintaining healthy blood glucose levels.
