Heart Disease and Vitamin D

There’s an interesting finding relating a lack of Vitamin D to the risk of heart attack and stroke:

MONDAY, Dec. 1 (HealthDay News) — A lack of vitamin D, which is absorbed primarily through exposure to sunlight, helps boost the risk of heart attacks and strokes, new research finds.

“There are a whole array of studies linking increased cardiovascular risk with vitamin D deficiency,” noted Dr. James H. O’Keefe, director of preventive cardiology at the Mid America Heart Institute in Kansas City. “It is associated with major risk factors such as high blood pressure, diabetes and stiffening of the left ventricle of the heart and blood vessels. Inflammation is really important for heart disease, and people with vitamin D deficiency have increased inflammation.”

O’Keefe is the lead author of a review of such studies to be published in the Dec. 9 issue of the Journal of the American College of Cardiology. Experts estimate that up to half of adults and 30 percent of children and teenagers in the United States are vitamin D-deficient, according to the report.

Recent data from the long-running Framingham Heart Study indicated that someone with vitamin D levels below 15 nanograms per milliliter of blood is twice as likely to suffer a heart attack, stroke or other cardiovascular problem within two years as someone with the recommended 20 nanograms per milliliter, the report said.

I wonder if this might not help to explain the observed phenomenon that the traditional Inuit diet despite being high in fat actually seems to be correlated with reduced levels of cardio-vascular disease. It contains non-sunshine quality sources of Vitamin D.
