New research suggests that fish is good for the old grey matter. Fish was always considered as ‘brain food’ by generation of housewives.
University of Manchester scientists have proved that vitamin-D is usually synthesized naturally when the skin is exposed to the ultraviolet rays of the sun.  This is also found in oily fish. Consumption of this fish can improve the brain functioning in middle aged and older men.
Results of the research were published in the Journal of Neurology, Neurosurgery and Psychiatry.
The study included compared the cognitive performance of more than 3,000 men. All men were aged 40 to 79 years at eight test centres across Europe.
Lead author Dr David Lee, in Manchester’s School of Translational Medicine, said, “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.”
“The main strengths of our study are that it is based on a large population sample and took into account potential influences, such as depression and levels of physical activity.” He adds, “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.
“The positive effects vitamin D appears to have on the brain need to be explored further but certainly raise questions about its potential benefit for those with or susceptible to dementia.”
Vitamin D also helps delay the mental decline that can affect people in old age.
Dr Iain Lang, of the Peninsula Medical School in Exeter, carried out the earlier research.
So now there is mounting evidence which suggests vitamin D was good for the brain.
