The Glycemic Index (GI) is a great way to look at what you eat and determine if what you are eating is any better than eating plain sugar. The GI is not on most labels but can be found easily on most foods on various Internet sites. The GI is a scale that compares other foods to sugar. Foods with a lower GI (less than 55) are easier to digest and provide a lower and slower rise in your blood sugar level and release of insulin. As an example, vegetables have a low GI, but candy has a very high GI.
