How does the Glycaemic Index classify foods?
Foods are given a GI ‘score’ to show how fast your blood sugar levels rise in response to an intake of carbohydrates. The higher the score, the faster the blood sugar level rises. A GI value of 70 or more is considered high, one of 56-69 is medium, and one of 55 or less is low. The lower the score, the slower the rate of carbohydrate absorption, and the lower the rise in blood sugar level.
