This got me interested in the data that exists with Vit D and heart disease.
There is a growing body of evidence that patients with Vit D deficiency have higher rates of heart disease.
Vit D defiency is common and appears to affect as many as one-third to one-half of otherwise-healthy middle-aged to elderly adult world-wide. Increasing age, female gender, nonwhite race/ethnicity, diabetes, current smoking, and higher body-mass index (BMI) have all been shown to have higher rates of Vit D deficiency.
It is NOT known yet if Vit D defiency causes heart disease or does the heart disease cause Vit D deficiency. There do appear to be biological reasons for why Vit D defiency may cause heart disease, including anti-inflammatory properties.
It is NOT yet known if patients with low levels of Vit D can dreduce their risk by taking viVit D supplementation.
The ARE some possible dangers in getting TOO MUCH Vit D.
The only way to know for sure if you are Vit D deficient is to test your blood levels.
In the mean time, it appears that the best way to ensure that you have enough Vit D is to get at least 10-15 minutes of sun every day and consume vitamin D rich foods like drinking fortified milk and eating oily fish (salmon, mackeral, herring, sardines).
