Understanding Nutrition Textbook and Study Guide

Whitney/ Rolfes 13th edition- 2012. For basic nutrition classes.Book is in good condition. Not really a textbook- more like papers with holes but none are missing and in good shape. Goes into a binder. Study guide is decent and mostly filled up with answers, which should be helpful ;-) paid at least $150 at the bookstore for both, can't get money back since there's a newer edition so selling on here for cheap.
