The glycaemic index (or GI for short) ranks carbohydrate containing foods on a scale from one to 100 based on how quickly and how much they raise blood glucose after eating.

Foods that cause the most rapid rise in blood glucose are given higher GI values, while those that cause more gradual rise in blood glucose are given lower GI values.

The table below groups common carbohydrate foods according to their GI value. Choose those with a lower GI for your meals.
