What does the glycemic index measure?

The glycemic index is a measure of how quickly a particular food raises blood glucose levels after consumption. It ranks foods on a scale based on their impact on blood sugar compared to a reference food, usually glucose or white bread. Foods with a high glycemic index can lead to rapid spikes in blood sugar, while those with a lower index result in more gradual increases.

This concept is crucial for individuals managing blood sugar levels, such as those with diabetes or those interested in improving their overall metabolic health. Understanding the glycemic index can help individuals make informed dietary choices that promote stable blood sugar levels and better overall health. While fiber content, caloric content, and fat content are important aspects of nutrition, they are not what the glycemic index assesses.
