First of all, I am fascinated by nutrition. It's a pretty cool thing to know how food contributes to our everyday existence. With that in mind, this book is a fantastic nutrition resource and reference. I've read a lot of extracurricular nutrition guides over the years and was under the impression I had a pretty good handle on the concepts. Nope. I felt like an amateur once I got into this book. There is so much more to learn and this book lays it out into a very "digestible" format.
