Regularly spending even relatively short intervals of only 10 to 15 minutes in the sunlight allows your body to produce vitamin D, and having adequate vitamin D3 levels can drastically reduce your risk of colon and breast cancer.
The researchers, from the Moore’s Cancer Center at the University of California, San Diego (UCSD), estimated that by increasing vitamin D3 levels, particularly in countries north of the equator, 250,000 cases of colorectal cancer, and 350,000 cases of breast cancer could be prevented worldwide.
In all, that amounts to 600,000 cases of breast and colorectal cancer prevented, including close to 150,000 in the U.S. alone.
This is an unprecedented study because it’s the first to take satellite measurements of sunshine and cloud cover in the same countries where blood serum levels of vitamin D3 had also been taken. In all, surveys of serum vitamin D levels from 15 countries were evaluated for the study during the winter when sunlight is at a minimum. continue reading:
Experts have warned the highly acclaimed “Slip Slop Slap” campaign may have been taken too far by a nation terrified of skin cancer.
Melbourne Pathology director Ken Sikaris, who oversees 1500 vitamin D tests a week, said the rate of deficiencies was “mind-boggling”.
Dr Sikaris said people had become overly protective when it came to sunshine, pointing out that Slip Slop Slap “is a pendulum and it’s gone a bit too far”.
“There’s a balance” you need sunlight but don’t go out in the middle of the day for an hour when the UV is most harmful,” he said.
Sydney endocrinologist Terry Diamond said under current recommendations 20 to 30 per cent of the population had deficient or insufficient levels of vitamin D. continue reading:
