A recent study found that vitamin D is essential for better learning and cognitive function especially for elderly.
The study, supported by the National Institution of Health, linked vitamin D availability in brain and cognitive abilities. Cognitive function is measured by the level at which the brain is able to manage and use available information for activities of daily life. Alzheimer’s disease, the most common form of age-related dementia, affects about 47 percent of adults aged 85 years or older in the United States. Identifying nutritional factors that lower cognitive dysfunction and help preserve independent living provides economic and public health benefits, according to authors.
Researchers evaluated 1,000 participants receiving home care. They measured vitamin D blood concentrations and neuropsychological tests for each of the participants. After analyzing the data, the researchers found that only 35% of the study subjects had sufficient vitamin D in their blood. Furthermore, this group of individuals had better cognitive performance on the tests than those who were vitamin D deficient.

Vitamin D is found in many dietary sources such as fish, eggs, fortified milk, and cod liver oil. The sun also contributes significantly to the daily production of vitamin D, and as little as 10 minutes of exposure is thought to be enough to prevent deficiencies.
