Vitamin D boosts

brain power in

middle-aged men

A new study says increased 

levels of vitimin D–found in 

certain foods such as oily fish–

are linked to higher cognitive 

power among middle-aged 

men.

A report of the British study, 

which will appear in the Journal

of Neurology, Neurosurgery 

and Psychiatry, 

found 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.” 

Researchers from the University

of Manchester, in collaboration 

with other European specialists,

compared the cognitive 

performance of more than 3,000

men aged 40 to 79 years at 

eight test centres across Europe.

They found 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.”

Resarchers “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 study is based on a large 

population sample and took into

account other possible factors, 

such as depression, season and 

levels of physical activity.

The excellent sources of 

vitamin D fatty fish and 10 

to 15 minutes daily exposure

to sunlight.
