Doctor admits that most MDs know nothing about nutrition, health

This article reminds me about a DO I visited once and whom I asked about fasting, and if she had any information about the subject.  Her reply was simply, "Oh, you should always get three square meals every day..." and words to the effect that she knew nothing about nutritional fasting (or nutrition, for that matter.)  I think I've only once in my life met a doctor who showed any interest in what I ate - and that was the doctor who helped me cure my hives (the other doctor I saw wanted me to be on Zyrtec for the rest of my life, without making any mention at all about diet or nutrition.)
