Glycemic Index or GI is a measure of the effects of carbohydrates on blood sugar levels.
Carbohydrates that break down more slowly, releasing glucose more gradually into the bloodstream, have a low Glycemic Index.
Carbohydrates that break down quickly during digestion and release glucose rapidly into the bloodstream have a high Glycemic Index.
Whole grains typically have a lower-GI value than refined grains and have a higher nutritional content with more fiber, vitamins, minerals and phytochemicals.
