Many, and probably most doctors will try to dismiss this question quickly if you ask them. They have divorced themselves from diet (saying "I'm not a dietician") and other factors.
Sadly, they have become puppets of the drug companies and they sling prescription pads like men in the old west slinged guns. They would probably consider you a bother or even a troublemaker for asking this. Their allegiance to the drug companies (and pleasing their drug overlords) is of paramount importance.
As you may guess, I don't think a lot of most doctors.
