The China Study is the biggest, most comprehensive nutritional study ever conducted. The study spans over twenty years and compare the standard American diet, or SAD (do you know how much I love that, haha) with the diets of those living in 65 counties in China (where they consume very little animal protein). Coronary heart disease, diabetes, leukemia, and cancers of the colon, lung, breast, brain, stomach and liver are actually considered Western diseases. Yikes! It's an amazing book and has absolutely nothing to do with animal rights. They just want people to stop dying from something so preventable. That some people eat crap and live to be 90 is amazing. Some people may smoke 2 packs of cigarettes a day and die of something completely unrelated, but we would never, ever, advocate for smoking. It's the same with food. Just because some dodged a bullet doesn't mean we should be placing others in the firing line.
