- In this edition, the questions in the "Nutrition Portfolio" feature are now correlated to Diet Analysis Plus and require users to use the dietary tracking information to evaluate and compare their personal dietary choices with dietary goals introduced in the text, exploring how their knowledge and behaviors have changed as their understanding of nutrition science progresses.
- The "Pop-up Tutor" lecture videos developed by Dr. Jessica Coppola at Sacramento City College reinforce key concepts and provide users with further instruction and practice on particularly difficult topics such as metabolism, digestion, and absorption. Users can access the Pop-up Tutors via CengageNOW and WebTutor for BlackBoard and WebCT and through links embedded in the CL eBook and Personalized Learning Plans.

- At the end of each chapter, "Nutrition Portfolio" sections invite users to evaluate and compare their personal dietary choices with dietary goals introduced in the text. The "Nutrition Portfolio" questions are now correlated to Diet Analysis Plus.

This was a required textbook for a Nutrition class. It is very informative but not written in such a way that it's difficult to grasp. The layout of the book is great as well. There are definitions in the margins as well as charts and graphs. NICE BOOK!!

Buyer beware. Purchasing this book through Amazon might save you a few bucks but you aren't purchasing the same version of the book you would get in a university bookstore. The Amazon version does not contain an access code to connect to the supplemental web support referenced multiple times in this textbook. When I called customer support I was told that since Amazon doesn't specifically say the book contains the access code, I shouldn't have expected it to. Thanks, Amazon.

I rented this book through Chegg last year for my nutrition class. If I had known ahead of time how helpful this book was going to be, I would've purchased it instead of just renting it. I got an A+ in my nutrition class and it's partly because of this book. I'm a nursing major so I definitely recommend this book for all future nurses. It's also a book that you will want to keep, rather than sell it back to a bookstore because it's great reference material.

Did not care for this book
I am not sure what to say, I have nothing good to say about this book. I do know that the year after I took this course, my college changed to a different nutrition book.

No New Nutrition
This book has very little new information in it, just like all of the other older editions. Unfortunately, knowledge about nutrition doesn't seem to have changed much.

Price is right.
Price wasn't too bad, considering the price you would pay for it at the college. I'm still in my semester for this class so I can't rate the whole book. Read more

Textbook not required
My professor doesn't require a textbook so for the most part this book is collecting dust. I have used the nutrition charts in the back and read some of the chapters. Read more
