none of them are "against" nutrition, they are just ignorant of it, and how it can heal and how it can cure. they just are not educated on the subject, thats all. they are educated on chemical based pharmacueticals, and thats the only thing they prescribe to cure and treat diseases. and they are so so so so wrong about that.
they do have broad general advice about diet and excercise, but not specific advice about how to treat this specific disease with a specific nutritional regimen.
