well, yes we do have meat eating teeth. they're there for a reason. although ive done some reading on cancer patients healing themselves through cycles of fasting and consuming raw fruits and veggies. organic would be the way to go to be more healthy (factory processed is obviously unhealthy). personally i believe, a great deal of the worlds cancers and disease originate with the consumption of factory processed foods, with all the chemicals they add to preserve etc.

back to the point: if you can find a way to quit smoking, im sure quitting meat would be a breeze.
