Query: Reading just the first fourth of the book turned me into a vegetarian.

All my life I scoffed at vegetarianism, even though both my brilliant adult children have been on it for decades. Stupid of me. But THE CHINA STUDY opened my eyes. Late in life all right, I'm 85, but for about 20 years since my triple bypass I've steered clear of red meat. Ate lots of fish, fruits, veggies and nuts. My numbers were pretty good and at least I haven't had any more heart procedures, but I still noticed a sharp rise in energy within 72 hours of going vegan. As a result, I've gone off of several of my medications and continue to feel fine without pumping so many toxic pills into my body.Unless you're part of the food or medical community, THE CHINA STUDY will blow your mind. You owe it to yourself to read it--right away.----Warren Jamison
