I have read it over and over, I know the science behind it, but I never really felt it til recently, red meat is just bad for MS. Among the many reasons for this, it is a major inflammatory substance which can worsen MS symptoms. Some people say they feel the effects within an hour of ingestion, but me? Usually takes a day or so. I had a steak last night, it was good, but I regret it now. Where I was once not so sensitive to dietary factors I now seem to be noticing some ill effects with certain foods.
