Shawin, I hate to break it to you, but T Colin Campbell's The China Study has been well and truly debunked. Our livers are not at all small, and our intestines are not made for a vegetarian diet, but for an omnivorous one, hence our teeth structure. Our front teeth are made for tearing flesh, which vegetarians like to conveniently forget.

Anyway, you can eat whichever way you prefer, but I still implore you to try some magnesium for the sake if your bowel comfort.

Re The China Study, here are a couple of rebuttals for you. There are many more. :
