Glycemic Index

This terms refers to the rise in blood sugar (glucose) from any given food as compared to pure glucose. For example, the GI of a bagel is 72; this means that the bagel causes blood glucose to rise 72% as much as pure glucose. Processed foods increase the GI whereas high fructose content foods and the co-ingestion of fat, fiber, and protein decrease the GI.
