The 6ยข pill that prevents cancer

From The Independent, online edition, December 28, 2005


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...

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. "

Countries around the world have begun to modify their warnings about the dangers of sunbathing, as a result of the growing research on vitamin D. The Association of Cancer Councils of Australia acknowledged this year for the first time that some exposure to the sun was healthy.

In the latest study, cancer specialists from the University of San Diego, California, led by Professor Cedric Garland, reviewed 63 scientific papers on the link between vitamin D and cancer published between 1966 and 2004...

Professor Garland said: "A preponderance of evidence from the best observational studies... has led to the conclusion that public health action is needed. Primary prevention of these cancers has been largely neglected, but we now have proof that the incidence of colon, breast and ovarian cancer can be reduced dramatically by increasing the public's intake of vitamin D."
In addition to its impact on cancer, a lack of vitamin D can mean increased risk of multiple sclerosis, osteoporosis, insulin resistance, and through its impact on insulin resistance, heart disease.

A 1000 I.U. supplement of vitamin D costs about 6 cents per tablet from online stores like
