My brother and I have high iron levels, though are pale-faced, and don't eat a lot of iron-rich foods. Ancestry is irish/scottish (predominantly Scottish). These regions have long been known to have a high incidence of MS:
According to the UK MS website:
'In Scotland, there is 137 per cent more MS than in England and Wales'.
In particular, Shetland and Orkney districts have four times the incidence of MS as mainland Scotland (1 in every 250 people from Shetland/Orkney have MS)
