Vitamin D helps regulate the amount of calcium and phosphate in the body which are known to keep bones, teeth and muscles healthy.
The most important and cheapest source of Vitamin D source is sunlight. Vitamin D is also found in a small number of foods like oily fish like salmon, red meat, egg yolks. Sources of vitamin are mentioned in this post.
These days we see more cases of deficiency of Vitamin D because people go out less in sun or use sunscreen to prevent suntanning, wrinkles and all but they miss out one of the most important vitamin.
Health benefits of vitamin D
We are in need of vitamin D to absorb calcium from the intestines and to reclaim calcium that could otherwise be excreted via the kidneys. Vitamin D is necessary for the growth of bone, its correct mineralization and remodeling by the action of osteoblasts and osteoclasts.
That is why it is not surprising that getting enough vitamin D is essential for warding off bone disorders, such as rickets in children, osteomalacia in adults, and osteoporosis in the elderly patients.
Studies conducted in adults have shown that Vitamin D supplementation improves insulin sensitivity. Studies have shown that Vitamin D and calcium influence pancreatic B cell function, insulin sensitization and systemic inflammation.
It has also been found that patients with Type II Diabetes Mellitus have decreased serum Vitamin D levels compared to non-diabetic control groups.
Epidemiological studies have shown an increase in the incidence of the disease with Vitamin D deficiency in the first month of the child’s life.
In Cardiovascular Disease:
The presence of Vitamin D receptors in cardiac muscle cells has been associated with Vitamin D against the development of several cardiovascular problems.
A study conducted in men, showed that the risk of suffering a myocardial infarction in those individuals who were deficient in Vitamin D, was double, compared with those who had levels within the normal range.
Vitamin D is really essential for regulating cell growth and also for cell-to-cell communication. A number of studies have indicated that calcitriol (the hormonally active form of vitamin D) may decrease cancer progression by slowing the growth and growth of new blood vessels in cancerous tissue, increasing cancer cell death, and reducing cell proliferation and metastases.
There are vitamin D receptors in brain tissue, which suggests that the vitamin may play a role in cognitive function and, possibly, the risk for dementia. Vitamin D may help clear amyloid plaque, the hallmark of Alzheimer’s disease (the most common type of dementia).
