It’s unfortunate that neither Stanford nor MIT have any free online nutrition courses (because they have other courses that are top-notch). Still, there are a few nutrition courses out there to help with your basic nutrition knowledge.

If you are trying to learn how to be a better coach, I highly recommend the Precision Nutrition course.
