All about Glycemic Index and Glycemic Load

I discuss the concepts of glycemic index and glycemic load extensively in my book, The Paleovedic Diet. If you would like to delve more into the science behind these concepts, the Linus Pauling Institute at Oregon State University has a high quality review of the literature available at:

If you are interested in looking at the glycemic index and glycemic load of over 2400 foods, the website of freelance writer and diabetes consultant David Mendosa is quite helpful. This site makes it easy to look over a large number of different types of foods to get a sense of where the glycemic index and load falls for each food:

If you have a specific food in mind that you would like to determine the glycemic index and glycemic load for, the best resource is the University of Sidney’s free online searchable database available at:
