Well, if you find the proper real life dietician, then that would be the best choice. Information on the internet can be confusing because people have different viewpoints that are not based on accurate, reliable, and repeatable studies. If your doctor(s) do not respond to your questions, then try a pharmacist(for side effects of meds) and a dietician(for your diet).

Myself, I just can repeat what I read in newspapers and the internet sources that sound the most realistic. So take what you like and leave the rest behind. Every person's body is different in terms of processing food and medications.
