Public health degrees used to require a nutrition course or it could be an actual specialty and many doctors that both practice and conduct research have a combined MD/MPH degree. This has been in place for a while, but not all doctors go into research. Doctors are also required to take continuing education credits but nutrition may not be a requirement. This gap makes me wonder if the nutrition courses were not prioritized because all of our food was going to be redesigned anyway with all these new medical technologies that were planned to go along with the "food as medicine" plan and precision medicine.
