The following is the portion of the 2008 text concerning MS and vitamin D

The incidence of multiple sclerosis (MS) varies with latitude. Ebers has co-ordinated a study 46 that examined more than 40,000 Canadian, British, Danish and Swedish patients with multiple sclerosis. The results show that in the Northern hemisphere, significantly fewer (8.5%) people with MS were born in November and significantly more (9.1%) were born in May. In the Southern hemisphere, the situation is reversed and November is the peak month and May the lowest. There are several clues as to the cause. An important study 47 compared the risk of two or more siblings having multiple sclerosis to the risk of its occurrence in both twins in a non-identical pair. There should be no difference, but non-identical twins do have a significantly higher risk of both having MS than non-twin siblings. This suggests that the pre-natal and post-natal environment affects the overall risk. Pinpointing the actual environmental factor has been problematic.

Correlations have been made between the incidence of MS, the availability of dietary vitamin D, and the availability of sunlight to drive vitamin D3 synthesis. In Japanese populations, who consume plenty of fish rich in vitamin D (90% of the Japanese vitamin D requirement comes from fish, 3% from eggs and 3% from milk), the MS prevalence is three per 100,000 population. MS has a very low frequency in equatorial regions where, it is argued, there is plenty of sunlight to drive vitamin D3 synthesis in the skin, whilst the incidence of MS increases dramatically with latitude in both hemispheres. In Scotland (in the north) and Tasmania (in the south), the prevalence is 250 per 100,000 population. Such arguments have also been used to explain two peculiar geographic anomalies on MS frequency, one in Switzerland with high MS rates at low altitudes and low MS rates at high altitudes, and one in Norway with a high MS prevalence inland and a lower MS prevalence along the coast. Ultraviolet light intensity is higher at high altitudes, resulting in a greater vitamin D3 synthetic rate, thereby accounting for low MS rates at higher altitudes. On the Norwegian coast, fish is consumed at high rates and fish oils are rich in vitamin D3 48.
