I recently used this book for class and found it so easy to use, straight forward and accurate. The version I received also had an accompanying CD which may or may not come with this version from Amazon.
This book covers the basics from the different types of nutrients to in depth details of vitamins, minerals, weight loss, child nutrition, and exercise.
Be sure that your professor wants the 7th edition, otherwise buy the one they are requesting. My professor was working off of the 6th edition and said that the 7th was fine but it is not! They moved some things around so you are working on different page numbers and there is not alcohol section in this book like there is in the 6th edition.
Other than that, I love this book and it is one of the few that I am not reselling. Good for a student, or anyone trying to learn more about nutrition and becoming healthy, active and a proper weight.
