glycemic index

The glycemic index (GI) measures how quickly carbohydrate-containing foods raise blood sugar levels after eating. Foods with a high GI are digested and absorbed quickly, causing rapid increases in blood sugar, while low GI foods are absorbed more slowly, leading to steadier blood sugar levels. For example, white bread has a high GI, whereas whole oats have a low GI. Understanding GI helps people choose foods that promote balanced blood sugar, which is especially useful for managing diabetes and maintaining energy levels. It's important to consider GI alongside portion size and overall diet for optimal health.
