My friend Kathy Freston has written a great book called "Veganist." You may have seen her talking about it last week on "Oprah." Kathy shares stories about people who have gotten healthier by switching to a plant-based diet, and gives a step-by-step guide for making an easy switch. Portia just finished it and she loved it. If you want to get healthier and have a positive effect on your body and the world, then this is the book for you.
