According to recent research, seniors who have insufficient levels of vitamin D have a higher risk of dying from heart disease than individuals with adequate levels of the vitamin.
The study, which analyzed the link between levels of the vitamin in the bloodstream and the death rates of those 65 and older, was published in the Journal of the American Geriatric Society.
It found that seniors with a vitamin D deficiency were three times more likely to die from cardiovascular diseases and two and a half times more likely to die from any cause, compared to those who maintained optimum levels of the vitamin.
The study’s lead author Dr. Adit Ginde, who works at the University of Colorado Denver School of Medicine’s Division of Emergency Medicine, explains that considering the aging U.S. population and the easiness with which vitamin D levels can be increased, "a small improvement in death rates could have a substantial impact on public health."
Vitamin D is found in milk, fish and eggs as well as cod liver oil and nutritional supplements. It is also produced in the body after exposure to the sun.
