I emailed Dr Katz Sand and here is her reply.
Thank you for your interest in our work! Of course I am quite familiar with Dr. Jelinek. The problem is that to really determine something has benefit in MS, it needs to be studied in a formal, scientifically rigorous fashion. This is why we are working hard to accomplish this goal. Hopefully we will be able to show that dietary changes can really benefit MS patients and help all of those living with this disease.

I bolded the "formal scientifically rigorous fashion", as it's both the good and bad news IMO. Unless covered by double blind, rigorous scientific fashion, and peer review, and further scientific rigorous research to confirm, (or rebutt), the findings of the initial research, then more peer review etc, all of which takes time, effort and money, very few things change.
My hope is, that those subjects of the research, find the site, and get their own information base to continue on the OMS path.
