It's quite a task! And making it all-organic adds to the challenge. But today of all times, with google and all the information available, it's a better time than ever to be able to plan meals that you know are going to be nutritious. When I said 'amateur,' I meant that I'M not a professional in a medical field.
I know some doctors refer patients to a professional for help planning meals when there is diabetes or some other metabolic challenge. Have you thought of checking in with your doctor and seeing if that kind of consultation is available to you?
