This was very easy to read because it's written at about the 6th grade level and is very repetitive, so you'll get the same info over and over again. That's helpful for those who are forgetful, but annoying to those who remember. It could have been half its length if carefully edited. Its extensive list of sources belies the simplicity of the prose, however, so while it is simple and easy to understand, apparently it is backed up with research. I wish that research were integrated into the book to enhance its credibility and to show where studies were being cited. If you're completely new to the world of glycemic load, this is a good start. If you are better informed, skip this book.
