                                The Glycemic Index (GI) was first introduced in 1981 by David J. Jenkins and his co-workers to provide a new way to classify carbohydrates based on their physiological effects on blood glucose. To truly understand its impact on your health, it's essential to know how to calculate GI formula, or more accurately, how the values are determined and applied to your diet.
