Query: The Multiple Sclerosis Diet Book

This is a very informative book for MS patients, as it explains how and why certain foods are either good or not-so-good pertaining to a person with MS. I was quite surprised and how many delicious recipes are included in this book. If put to use, I believe this knowledge can be especially helpful in prolonging periods of remission.
