"Revealed: the pill that prevents cancer

A daily dose of vitamin D could cut the risk of cancers of the breast, colon and ovary by up to a half, a 40-year review of research has found. The evidence for the protective effect of the 'sunshine vitamin' is so overwhelming that urgent action must be taken by public health authorities to boost blood levels, say cancer specialists.
A growing body of evidence in recent years has shown that lack of vitamin D may have lethal effects. Heart disease, lung disease, cancer, diabetes, high blood pressure, schizophrenia and multiple sclerosis are among the conditions in which it is believed to play a vital role. The vitamin is also essential for bone health and protects against rickets in children and osteoporosis in the elderly.
Vitamin D is made by the action of sunlight on the skin, which accounts for 90 per cent of the body's supply. But the increasing use of sunscreens and the reduced time spent outdoors, especially by children, has contributed to what many scientists believe is an increasing problem of vitamin D deficiency.
After assessing almost every scientific paper published on the link between vitamin D and cancer since the 1960s, US scientists say that a daily dose of 1,000 international units (25 micrograms) is needed to maintain health. ' The high prevalence of vitamin D deficiency combined with the discovery of increased risks of certain types of cancer in those who are deficient, suggest that vitamin D deficiency may account for several thousand premature deaths from colon, breast, ovarian and other cancers annually,' they say in the online version of the American Journal of Public Health."
Good news!
