Ok, I'm currently watching Forks Over Knives... I am only about halfway through it and will definitely give the whole thing a chance, but it doesn't strike up the same passion and determination that Fed Up did. I just don't fully agree with the "plant based diets are the only way to go and they will make us healthy and cancer free". That's the takeaway I have so far - maybe I'm missing something? I think plants are an essential part of a healthy, well-balanced diet, but I just think that animal-proteins are equally important. It's just obvious (in my opinion) that we were designed to consume animal-proteins. There are nutrients in animal-proteins that your body needs. THAT BEING SAID, I do think that we need to be eating the RIGHT animal-proteins. Fatty proteins, high-processed proteins, those aren't doing your body any good. Taco Bell ground beef is NOT a good example of an animal-protein. KFC fried chicken isn't either. I'm not saying plant-based diets don't work. I have a friend who is in amazing shape who is vegan, and she supplements her lack of animal-protein with protein powders and vitamin supplements, and she spends a lot of time in the gym and lifting weights and running marathons. But she does have to supplement a lot of her diet because she made the choice to cut out animal products. The fact that she has to supplement means that her plant based diet is not enough on it's own. I have another friend who is a vegan, but she is as overweight as I am. I don't think she supplements to the extreme that my other friend does, if at all, and I KNOW she isn't working out.
I think the bigger issue isn't necessarily animal proteins, but what is done to the animal proteins between the animal and your plate.
Edit: Case in point - further into the documentary, they have an older Chinese man (I didn't catch his name) and they talk about how healthy he was in China, but when he came to America and started eating "what Americans eat", he became unhealthy and his arteries clogged and he had a 5-bypass. They say it's because he started eating animal-protein, BUT what they're showing is him eating McDonald's, Burger King, and KFC. It's just kind of common sense that you won't be healthy if that's the majority of your diet, ESPECIALLY if you've always eaten the plants you grew yourself and then suddenly start eating pure junk.
