It has taken me some time to find full text documents regarding clinical trials on diet and omega3/omega6 suppliments mentioned here and in the book. Most of google search returnes only abstract's and not full text. I'm not sure why this is so, but i think we deserve to have access to this documents. So here is a link to ZIP file download that i have put together.
Just click on lower right side, where it writes "Save file to your PC".
I hope you find this interesting as much as i did, and that it gives you new motivation in fighting MS. Best health to all.
