raw foods: i'm already vegetarian (almost 2 years now). i used to be vegan and i've realized that ever since i stopped being vegan and started eating a lot of junk food, my immune system has weakened. is it such a bad idea to not eat dairy at all and live on a predominately raw foods diet? (i know i could never be 100% raw foodist)|||Dairy is bad for you. Humans are not supposed to drink cow's milk - it's absurd. But the dairy companies have got the entire country thinking you need three glasses a day. What a crock. Logically, it makes NO sense. Raw food is the best you could do for your body. It's very hard though.
