If you want to read a book that will, without a doubt, change your life then you must read The Food Revolution by John Robbins.
I believe the most important thing for people is to be educated about their food choices. It is important to fully understand why we eat particular foods and where that food is coming from.
The Food Revolution is the first book that truly jump started my new way of living. Even before I finished the book, I stopped eating meat...cold turkey, no looking back. It changed my life and I am so much healthier, happier, and stronger.
