Vitamin D & Calcium Reduce Breast Cancer Risk

Posted Nov 04 2009 12:00am
Vitamin D has been one of the most, if not the most, talked about vitamin in 2009.  Clinical and pre-clinical research continues to be published on the importance of appropriate vitamin D levels for protection against a variety of chronic conditions.  In fact in an earlier blog, I discussed some new vitamin D and breast cancer research that examined vitamin D levels in breast cancer patients. 

A new meta-analysis published online ahead of print in the journal Breast Cancer Research and Treatment provides more support for vitamin D, as well as calcium, for breast cancer protection.  For their analysis, researchers examined data from 21 studies on vitamin D (intake and blood levels) and breast cancer risk and 15 studies on calcium intake and breast cancer risk.  The results of their vitamin D analysis showed that as vitamin D intake increased, breast cancer risk decreased slightly.  Furthermore, examination of blood levels of vitamin D showed that the highest blood levels of 25-hydroxy vitamin D were associated with a 45% reduction in breast cancer risk compared to the lowest levels.  Analysis of the calcium data showed that the highest level of calcium intake was associated with a 19% decrease in breast cancer risk.

These data provide excellent support for the concept that diet and nutrition can have an important and beneficial impact on breast cancer risk.  To learn more about the importance of vitamin D and to find out my top 10 foods to fight against breast cancer, read my book Fight Now: Eat & Live Proactively Against Breast Cancer (
