Vitamin D levels linked to memory
Tuesday, 23 September 2014 00:00
People who do not get enough vitamin D could double their risk of developing dementia, say researchers, in what is considered to be the first large population-based study of its kind. For the study, published in Neurology, the researchers tested 1,658 dementia-free people over 65 years of age who had participated in the US population-based Cardiovascular Health Study. Their vitamin D levels were tested, with follow-ups for an average of 5.6 years. During this period, researchers found participants with low levels were 53 per cent more likely to develop dementia, while this rose to 125 percent for those severely deficient in vitamin D, when compared with participants with regular levels. So runners, as winter approaches, top up your vitamin D by eating plenty of fresh leafy greens, oily fish, and catch some sun when you can.
