We don't know if dairy affects MS, but some people have theorized that it MS is caused by "leaky gut", and suggest we stay away from dairy.

I am allergic (or maybe just sensitive) to either a protein or the calcium (can't remember) in dairy. I had several health issues that pointed directly at the necessity to avoid dairy, so I mostly cut it out about 30 yrs ago. The only time I consumed a significant amount of dairy after that was when I lived on a farm in New Zealand . . . and within a month of arriving back home, I had my first serious MS attack.

If dairy does have anything to do with MS, it may be the reason that I am still relatively ok after 18 definite years (possibly 30+) with MS.

There is more information about dairy and MS in the theory behind the "Swank Diet", which some people try to follow to manage this disease.
