Vitamin D may cut colorectal cancer risk by 40 per cent

Vitamin D may cut colorectal cancer risk by 40 per cent: "Increased blood levels of vitamin D may reduce the risk of colorectal cancer by as much as 40 per cent, says a study with people from 10 European countries.
The study, published in the British Medical Journal, is said to be the largest of its kind to date and adds to the science supporting the apparent health benefits from increased vitamin D. Indeed, a meta-analysis published in the American Journal of Preventive Medicine in 2007 reported that higher blood levels of vitamin D were associated with a lower risk of colon cancer.

The link between vitamin D intake and protection from cancer dates from the 1940s when Frank Apperly demonstrated a link between latitude and deaths from cancer, and suggested that sunlight gave 'a relative cancer immunity'."
