WHAT IS GLYCEMIC INDEX (GI)?
GI indicates how rapidly the body digests a particular type of food and converts it into blood sugar (glucose). Foods with high GI values contain rapidly digested carbohydrates which produce large and rapid increases (spikes) in our levels of blood glucose.
Scientific studies suggest that low-GI diets (ie, GI value of less than 55) may offer important health benefits because slowly digested carbohydrates produce gradual, relatively low increases in our levels of blood glucose.
