What is the Glycemic Index?

The Glycemic Index -- sometimes known as "GI" -- is a scale that ranks the way different foods affects your blood glucose. Choosing foods with a low GI rating can help lower your blood glucose levels and moderate your appetite. Foods with a low GI index tend to be very healthy, with plenty of fibre and nutrients. Eating low GI foods--more often than medium or high foods -- is a great way to moderate your blood glucose levels.
