Vitamin D(ementia)

According to a study carried out with the help of 850 older people over a period of 8 years by researchers at the Peninsula Medical School, the onset of dementia can be linked with low levels of Vitamin D. The tests revealed that those participants whose blood samples contained 70 % less Vitamin D than normal were by 60 % more likely to develop dementia. A good source of Vitamin D is fish, however, it is important to make sure that it comes from a reliable source, due to possible high levels of toxins in some kinds of fish (for further info, here is an interesting link: http://www.sciencedaily.com/releases/2003/02/030210080251.htm )
Our bodies are able to produce Vitamin D, but to do so it is essential to get as much natural light as possible. Therefore, it is important to get as much daylight as possible and to eat a balanced diet. A good Vitamin-D supplement can help, too.
