Low-glycemic index diet: What's behind the claims?

Diet details

If you follow a low-GI diet, your foods with carbs are mostly limited to choices with low values. You usually will avoid foods with high values. Examples of foods with low, middle and high GI values are:

  • Low GI: Green vegetables, most fruits, raw carrots, kidney beans, chickpeas and lentils.
  • Medium GI: Sweet corn, bananas, raw pineapple, raisins, cherries, oat breakfast cereals, and multigrain, whole-grain wheat or rye bread
  • High GI: White rice, white bread and potatoes

Commercial low-GI diets may refer to foods as having slow carbs or fast carbs. This is because foods with a low GI value are digested and absorbed over a longer time. Foods with high values are absorbed over a shorter time.
