Ten minutes of sun 'could stop 30,000 cases of cancer', researchers say: The researchers believe vitamin D deficiency may be to blame for 600,000 cancer cases worldwide each year, particularly in northern European countries where sun exposure levels are relatively low.
...In the latest study, scientists at the Moores Cancer Centre at the University of California, San Diego, estimate that 250,000 cases of colorectal cancer and 350,000 cases of breast cancer could be prevented worldwide by increasing the intake of vitamin D3.
...The study combined data from surveys of blood levels of vitamin D during winter from 15 countries, along with satellite measurements of sunshine and cloud cover.
...Dr Cedric Garland, the cancer prevention specialist who led the study, said: "This could be best achieved with a combination of diet, supplements and short intervals - ten or 15 minutes a day - in the sun."
