Vitamin D enhances cognitive function
Thu, 21 May 2009 06:41:20 GMT
A British study has revealed that higher levels of vitamin D are associated with increased brain power among middle-aged men.

According to the report, the link between increased vitamin D and faster information processing "was more significant in men aged over 60 years old, although the biological reasons for this remain unclear."

The study revealed that men with higher levels of vitamin D "performed consistently better in a simple and sensitive neuropsychological test that assesses an individual's attention and speed of information processing."

Researchers "observed a significant, independent association between a slower information processing speed and lower levels of vitamin D," said lead author David Lee at Manchester's School of Translational Medicine.

The cognitive performance of more than 3,000 men between the ages of 40 and 79 years were studied and compared by researchers from the University of Manchester, in collaboration with other European specialists.

The results of the study have been published in the latest issue of the Journal of Neurology, Neurosurgery and Psychiatry.

Fatty fish and daily exposure to sunlight are considered excellent sources of vitamin D which also helps cells absorb calcium and is important for bone health.

A previous study in Amsterdam in 2008 suggested that a lack of vitamin D could increase the risk of depression or other psychiatric issues among older individuals.
