Vitamin D reduces the risk of certain cancers
|
A study published in the American Journal of
Public Health, has found that vitamin D deficiency may account for several thousand
premature deaths annually.

The researchers reviewed 63 studies on the relationship between vitamin D and certain types of cancer worldwide
between 1966 and 2004. The majority of studies found a protective relationship between sufficient vitamin D status
and lower risk of cancer, especially in cancers of the colon, breast, prostate and ovary.
Vitamin D is acquired either through the diet or through exposure to sunlight. Food sources include milk, yogurt,
cheese, and fortified orange juice. A typical serving provides approximately 100 international units (IU).
Researchers suggested that people might want to consider a vitamin supplement to raise their overall intake to
1,000 IU's per day. Supplementing with additional vitamin D could be especially important for people living in
northern areas, which receive less vitamin D from sunlight.
The evidence suggests that improving vitamin D status through diet and supplements could reduce cancer incidence
and mortality at low cost, with few or no adverse effects.
