For the most part, no. Medical schools don't really teach nutrition as a science. Hospitals have dietitians who are specially trained in nutrition. The thinking is that dietitians should handle that specialty and it would be unnecessary overlap to teach docs the same thing. That's why you get generic advice from MDs to lower your fat intake, increase fiber, exercise more, etc. but not much more than platitudes. Just as a physical therapist is the specialty you need for rehabilitating after an injury (rather than an orthopedic surgeon) a dietician is best suited to give nutritional advice rather than a GP medical doctor. Obviously exceptions exist and specialist MDs know more than dietitians, but the General rule holds true generally.
