It is very important for people with diabetes to manage their glucose intake carefully.
Low GI and GL diets may be helpful to people with diabetes because low GI and GL foods may release glucose into the bloodstream slowly and more evenly than high GI and GL foods, making glucose levels easier to regulate.
Jennie Brand-Miller is Professor of Human Nutrition at the University of Sydney and a leading researcher in the development of the GI. She says that "choosing low GI sources of carbohydrate is a natural way of keeping blood glucose levels on an even keel, which helps people avoid marked fluctuations." However, the GI or GL should clearly not be the only point of reference in managing carbohydrate intake; instead they should be used as tools.
