I think you need a new doctor.
In all seriousness, of course it is true that nutritionists know more about nutrition than do doctors. Perhaps there is some set of foods that could prevent MMR (if there is, please let me know) about which doctors are ignorant. What does this have to do with the contention that vaccines cause autism?
I think it is reprehensible and slanderous to assert that the many thousands of doctors who strongly encourage their patients to get vaccinated (including, by the way, ???? ?????? ???? ????, as you know better than I do) are all willing to toss their own souls, along with the lives of their patients, to burn on the altar of the dollar god. This is not like recommending brand name Advil over store brand ibuprofen!
My pediatrician as a child, and nearly all of the many pediatricians I have used for my own children, are frum Yidden whose value for human life renders any dollar amount inconsequential. Are they, too, motivated by money or politics? Or perhaps they are too stupid to figure this all out? Many of them have the highest pedigree you could want a physician to have; do they not understand the issues?
