Eat oily fish to keep brain healthyMay 27th, 2009 - 5:36 pm ICT by IANS
London, May 27 (IANS) Eating oily fish, rich in vitamin D, may be vital in keeping your brain healthy as you age, according to a new study.
University of Manchester scientists and other researchers have found that higher levels of vitamin D, synthesised in the skin following sun exposure, is also found in oily fish.
The study assessed the cognitive performance of more than 3,000 men aged 40 to 79 years at eight test centres in Europe.
It was found that men with higher levels of vitamin D performed consistently better in a simple and sensitive neuro-psychological test that assesses an individual’s attention and speed of information processing.
“Previous studies exploring the relationship between vitamin D and cognitive performance in adults have produced inconsistent findings. But we observed a significant, independent association between a slower information processing speed and lower levels of vitamin D,” said study author David Lee of Manchester’s School of Translational Medicine.
“The main strengths of our study are that it is based on a large population sample and took into account potential interfering factors, such as depression, season and levels of physical activity,” Lee said.
“Interestingly, the association between increased vitamin D and faster information processing was more significant in men aged over 60 years, although the biological reasons for this remain unclear,” he added.
These findings were published in the Journal of Neurology, Neurosurgery and Psychiatry.
