Vitamin D Supplements along with sunlight offer protection against breast cancer

Jan 03, 2011

     Numerous studies have linked sufficient blood levels of Vitamin D to a decreased incidence of cancers including breast cancer. Researchers from INSERM led by Dr Pierre Engel collated data from 67,721 women who were followed for up to ten-years.
     The French researchers documented 2,871 cases of breast cancer in these women over the decade long study. If the women lived in what the French referred to as a sunny region (generally below latitude 46º N; this would pass through Lake Como in Northern Italy and the Oregon-Washington border in the USA) and they had a high dietary intake of Vitamin D the risk of having breast cancer dropped by 32%. If they had a good deal of daily UV exposure and they took high doses of Vitamin D as a supplement their risk dropped by 45%.  The study is published online ahead of print in the journal Cancer Epidemiology, Biomarkers and Prevention.
