Does eating fish daily help MS patients?
There is some data that suggests an association between regular consumption of fatty fish and reduced incidence of MS. However, these studies do not establish a "cause and effect" relationship between the two (only a randomized clinical trial can do that). The hypothesis is that fatty fish have large amounts of vitamin D (which also has demonstrated an association with lower MS incidence and disease activity). I typically suggest to my patients that supplementing their diet with vitamin D3 is advisable as doing so may help MS (although we don't know this or sure) and it can also help with bone health (which we do know). Hope this helps.
