Vitamin D found in fish boosts brain power
May 21, 2009Eating fish - long considered 'brain food' - may really be good for the old grey matter, as is a healthy dose of sunshine, new research suggests.
University of Manchester scientists in collaboration with colleagues from other European centres have shown that higher levels of vitamin D - primarily synthesised in the skin following sun exposure but also found in certain foods such as oily fish - are associated with improved cognitive function in middle-aged and older men.
The study, published in the Journal of Neurology, Neurosurgery and Psychiatry, compared the cognitive performance of more than 3,000 men aged 40 to 79 years at eight test centres across Europe.
The researchers 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.
"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 lead author Dr David Lee, in 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.
"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 minimising ageing-related declines in cognitive performance."

Life Extension - Vitamin D3 (1000iu), 1000IU, 250 capsules by Life Extension Vitamin D is necessary for utilization of calcium and phosphorus and in many ways acts as a hormone.78-80 The two most important forms of vitamin D are cholecalciferol (D3), which is derived from our own cholesterol and ergocalciferol (D2), a plant analogue derived from the diet. The cholecalciferol supplied by the Life Extension Buyers Club is synthetic, but its form is identical to that which is derived from cholesterol and synthesized by sunlight on the skin. Cholecalciferol Vitamin D is essential for bone growth and maintenance of bone density. A dietary deficiency of vitamin D inhibits the production of the protein that binds calcium in the intestines, so that calcium cannot be absorbed, even if there is adequate intake. Deficiencies of vitamin D are often found in the elderly and... | ||||||

The Vitamin D Revolution: How the Power of This Amazing Vitamin Can Change Your Life by Dr. Soram Khalsa M.D. (Author) Recent, groundbreaking medical research has made a connection between Vitamin D deficiency and 17 types of cancers, including breast, colon, and prostate. Illnesses such as influenza, diabetes, multiple sclerosis, and coronary heart disease have also been connected to a lack of this vitamin. Until not too long ago, not getting enough Vitamin D (the sunshine vitamin) was only associated with rickets, the childhood bone disease.
