Multiple sclerosis is a disease of unknown cause characterized by demyelination (loss of the protective coating around nerves) in the brain.
From The Journal of Nutrition:
A Mediterranean diet, including unprocessed red meat, was associated with reduced risk of [first clinical diagnosis of brain demyelination] in this Australian adult population. The addition of unprocessed red meat to a Mediterranean diet may be beneficial for those at high risk of [multiple sclerosis].

So this has nothing to do with diabetes; just more support for the general healthfulness of the Mediterranean diet.
