W and i listened to "In Defense of Food" by michael pollan on our cross country journey. i think it's safe to say it was an eye opener for both of us. if you have not read this book, i highly recommend you get your hands on a copy. or, listen to it on CD. listening to it was probably the best way for my to digest the information since there is so much of it and it does tend to get a little repetitive and scientific.
it confirmed a lot of the "clean eating" ways of thinking i have adapted but changed some things in my mind. i will be sticking more firmly to this rule: if it has more than 5 ingredients on the ingredients list or i cannot pronounce some of the ingredients, i will not be buying it.
you can get it on amazon and i encourage you to do so.
