The glycemic index (GI) is a rating system for foods that contain carbohydrate. It helps you know how quickly these foods raise blood sugar.
Carbohydrate raises blood sugar more quickly than other nutrients, like proteins and fats. Some carbohydrate foods raise blood sugar faster than others.
Foods in the index are ranked by number.
Some people who have diabetes use the glycemic index to help them plan meals and manage blood sugar.
