More scientific and medical proof on the high importance of Vitamin D
A recent study published online in the journal Neurology on August 6, shows that elderly participants with extremely low levels of vitamin D were more than twice as likely to develop dementia and Alzheimer’s disease, as opposite to seniors with sufficient levels of the sunshine vitamin.
This study is considered to be the largest and most robust of its kind to find an association between low levels of vitamin D and Alzheimer’s & dementia. The international team that conducted the study was led by Dr. David Llewellyn at the University of Exeter Medical School.
The research was based on 1,658 adults aged 65 and over, able to walk unaided and free from dementia, cardiovascular disease and stroke at the start of the study. They were then followed for six years to investigate who went on to develop Alzheimer’s disease and other forms of dementia.
“We expected to find an association between low Vitamin D levels and the risk of dementia and Alzheimer’s disease, but the results were surprising – we actually found that the association was twice as strong as we anticipated” –Dr. David Llewellyn said.
The study also found that vitamin D levels above 50 nmol/L (nanomoles per liter) are most strongly associated with good brain health, and the risk of dementia and Alzheimer’s disease increases with levels below that mark. However, clinical trials are now needed in order to determine whether eating foods such as oily fish or taking vitamin D supplements can delay or even prevent the onset of Alzheimer’s disease and dementia, but these results are a great start.
How to keep good blood levels of Vitamin D?
Vitamin D is essential for your body to absorb calcium and maintain bone health. It is also thought to moderate cell growth and help control immune functions and inflammation. It can be obtained through food, through the skin after exposure to sunlight and from supplements.
