What is the Glycemic Index?
The glycemic index (GI) is a ranking of carbohydrate-containing foods based on their effect on blood glucose levels. It ranges from 0 to 100, with higher numbers indicating foods that spike blood sugar rapidly.
Foods are ranked based on how much they raise blood sugar compared to a reference food, usually glucose or white bread:
- Low GI foods = 55 or less
- Medium GI foods = 56 to 69
- High GI foods = 70 or more
It's important for diabetics to focus on low GI foods, which get absorbed slowly and prevent drastic rises in blood sugar.
Benefits of a Low Glycemic Diet
Here are some of the key benefits of following a low glycemic diet for diabetics:
