Vitamin That May Protect One Against Heart Attack!

If one’s body is deficient of certain type of vitamin, he or she may face a high risk of having heart attack. In January 2008, researchers from Harvard Medical School reported that people with low level of Vitamin D might have a higher risk for heart attack, heart failure and stroke. The study was published in June 2008 in the journal Archives of Internal Medicine.
In their study of identifying possible health benefits from Vitamin D, researchers from the Harvard School of Public Health and Brigham and Women's Hospital in Boston found that men with low levels of Vitamin D have a higher risk of getting heart attack.
The study involved 454 health professionals ages between 40 and 75 who had suffered a nonfatal heart attack or died of heart disease, and 900 other men with no history of cardiovascular disease. These subjects were followed for 10 years after providing blood samples to measure their Vitamin D levels.
The researchers compared participants who were deficient in Vitamin D (no more than 15 nanogrammes per milliliter of blood) with participants who were in the lower end of the normal range (at least 30 nanogrammes per milliliter of blood).
Men classified as deficient in vitamin D were about 2 and a half times more likely to have a heart attack than those with higher levels of the vitamin. In fact, those with low Vitamin D, besides being at higher risk for heart attack, were at particularly high risk to have a fatal heart attack.
Vitamin D is also known as “sunshine vitamin” because body makes Vitamin D when the skin is exposed to sunlight. It can be found in milk and fatty fish like salmon. Vitamin D helps our body to adsorb calcium and benefits bone health. Vitamin D deficiency can lead to osteoporosis for adults, rickets for children.
Several recent studies have also indicated that Vitamin D may offer a variety of other health benefits. This includes protecting against colon cancer, breast cancer, peripheral artery disease and tuberculosis.
Vitamin D may protect against heart attack in a number of ways. It might lower blood pressure, regulate inflammation, reduce calcification of coronary arteries, affect the heart muscle or reduce respiratory infections in winter.
To find out whether one’s Vitamin D level is normal, just visit the family doctor and take a blood test. Those with very low levels can take Vitamin D supplements.
