Vitamin D is important in cardiovascular health
February 14th, 2008
Although the negative effects of vitamin D deficiency on bone health are well documented, there is emerging evidence that vitamin D is important in cardiovascular health. Vitamin D may decrease blood pressure, as well as regulate the growth and proliferation of vascular smooth muscle cells. It is thought that Vitamin D deficiency may be present in up to one half of older adults, and inadequate sun exposure, skin pigmentation, and dietary deficiency can all contribute to reduced body stores of vitamin D.
A study including 1,739 participants, published in Circulation (online) in January, concluded that individuals classified as having Vitamin D deficiency were at increased risk of cardiovascular events. The higher risk associated with deficiency was particularly evident among individuals with hypertension, in whom deficiency was associated with a two-fold risk.
So how can you increase your vitamin D levels? The easiest way is to increase your daily sun exposure but unfortunately, in many parts of the world, this is not always possible and, for some susceptible individuals, may be unwise. You can increase your intake of vitamin D rich foods which include butter, egg yolk, mackerel, oysters and salmon; butter and egg yolk are not recommended for patients with heart disease or high cholesterol. Vitamin D supplements can be taken orally and this can be discussed with your consultant at London Medical.
