Studies have shown that lack of Vitamin D can actually bring serious health problems to the human body. Considering the fact that it affects about 85% of Americans, it is safe to say that the effects that come with Vitamin D deficiency are under-recognized.
Vitamin D has been known to be the root of many health conditions from autoimmune complications to depression and heart diseases. The fact that Vitamin D directly affects up to 30,000 genes in human bodies should be enough reason for anyone to make sure he/she is on the know about it.
Vitamin D play a major role in the balancing of Th-1 and Th-2 immune system responses. It achieves this by controlling cells known as Treg (T- regulatory) that create the differentiation and expression of Th-1 and Th-2 immune system responses. Any imbalance between these cells is bound to lead to autoimmunity.
Studies done by the medical community and researchers have shown a direct link between Vitamin D deficiency and human life expectancy. The researchers found out that low levels of Vitamin D will negatively affect one’s life expectancy while healthy levels of the same will not only increase their life expectancy, but will also come with a number of health benefits. According to Dr. Grant, a vitamin D expert, Vitamin D is capable of reducing the number of cancer deaths annually by up to 30%.
Another study in Turkey showed that about 92% of Hashimoto’s patients had Vitamin D deficiency. The same study suggested that the levels of Vitamin D that define normal need to be increased from the recommended Daily Allowance of 400IU.
The levels of Vitamin D required in the human body for proper immune functioning is between 60 and 80 ng/L. Therefore, it is advisable to keep track of Vitamin D on a regular basis, especially during the winter. Campaigns such as skin cancer awareness and prevention of sunscreen have hindered the people from getting enough Vitamin D from the sun during summer.
