A walk in the sun may be beneficial - Vitamin D may help prevent cancer
A recent article in the Journal of the National Cancer Institute demonstrates a correlation between low levels of vitamin D in men, and enhanced risk for cancer. It suggests that maintaining a high level of vitamin D (equivalent to taking 1500 IU a day) may reduce cancer risk by about 20%, and cancer mortality by about 30%. We note that this is only a correlation - there is no proof that taking vitamin D will actually impact one's cancer risk. However, subsequent research published in the Journal of the National Cancer Institute (online, Nov 2008) shows that vitamin D supplements have no effect on the incidence of breast cancer, and that there is no correlation between vitamin D levels in the blood and breast cancer.
