Vitamin D deficiency is one of the most prevalent deficiencies in the world and one of the most dangerous. It can lead to poor bone density, increased chances of developing cancer and higher blood pressure. A deficiency can also lead to calcium deposits in your arteries, which will cause atherosclerosis over time. By getting your vitamin D levels checked, you can ensure that you do not have a deficiency and avoid the side effects that come along with it.
What Causes Deficiency?
The leading causes of vitamin D deficiency are old age, genetics and lack of sunlight. As you age, your body loses its ability to generate as much vitamin D from sunlight. The high levels of melatonin in dark-skinned people block proper functioning of the vitamin D precursors that create vitamin D.
Calcium Deposits in Arteries
Vitamin D increases the amount of calcium that is absorbed as blood is filtered through the kidneys. In vitamin D deficient individuals, higher levels of calcium are left flowing through the blood stream. The higher levels of calcium create calcium deposits within arteries, which can lead to cardiovascular problems.
Dangers of Calcium Deposits
Calcium deposits in the blood stream can lead to higher blood pressure because more pressure is put on the artery walls when it has to pass through clogged arteries. The calcium deposits stiffen the blood vessels as well, which can lead to increased blood vessel breakages that will cause scarring that further clogs the vessel passageways. One study found that men with low vitamin D levels were twice as likely to develop heart disease.
Sources of Vitamin D
The average person can avoid vitamin D deficiency simply by going out into the sunlight for a few hours each week. As sun shines on your skin, it is converted into vitamin D-3 at a rapid rate. If you have dark skin or are elderly, it will take significantly longer to develop the necessary amount of vitamin D through sunlight exposure. Even if you have trouble getting out into the sunlight enough to meet your vitamin D requirements, it is possible to get the necessary amount from food. Many freshwater fish have high levels of vitamin D. Milk, orange juice and other dairy products are also often fortified with vitamin D.
