Low levels of vitamin D appear to increase the risk of conditions such as Alzheimer’s disease, according to a major study by the University of Exeter.
The new study – the largest of its kind – found that a severe lack of vitamin D among the over 65s appears to more than double the risk of the condition.
Scientists were surprised by the dramatic findings, which suggest that increasing your intake of vitamin D, which comes from sun exposure as well as oily fish and eggs, could delay or prevent conditions such as Alzheimer’s disease. However, winter sun in the UK can be too weak to generate adequate vitamin levels and older people’s skin is less efficient at doing so.
NHS advice suggests all those over 65 should consider taking a daily 10 microgram supplement. Vitamin D can also be found in fatty fish such as salmon, tuna and mackerel, as well as in eggs and fortified foods.
Dr Simon Ridley, head of science at the charity Alzheimer’s Research UK, said: “Everyone should ensure they are getting enough vitamin D, but those thinking of taking supplements should speak to their GP.”
