I agree with a lot of the reviews, specifically the ones who mentioned the shows being pro vegan. What did the mayor of NYC have to do with this study? Nothing. The whole sexual thing and checking the heat of peoples genitals was just SO out there and really didn't need to be in the shows. The education about the cow/pig/chicken farming was interesting. I don't eat those things but was still interesting. I've also never seen salmon like what they showed in the shows, that was the nastiest piece of fish I've ever seen. I'd like to have known more about their blood test results, I don't think we ever know what their good cholesterol # was. I wanted to know if their iron levels changed, that kind of info. Did their blood pressure change much, and other vitamin levels. All the men seemed pretty fit too, should have had chubby guys since it would be nice to see if the vegan diet helped the guys.
