Calcium and Vitamin Intake Might Reduce Breast Cancer Risk

Posted Apr 20 2010 6:47am
Vitamins and minerals are essential parts of human nutrition and a lack of adequate amounts can lead to various chronic health conditions.  Research over the years has reported that taking additional vitamins and minerals might or might not help reduce the risk of cancers, including breast cancer.  A new breast cancer research study reports that regular intake of calcium and vitamins might substantially reduce breast cancer risk.

In this new breast cancer study , presented at the 101st Annual Meeting of the American Association for Cancer Research , researchers explored the relationship between breast cancer risk and consumption of vitamins and calcium and attempted to examine the mechanism by which calcium and vitamins might be beneficial.  For this breast cancer study, the researchers compared dietary supplement use, DNA repair functions, and other information between 268 breast cancer cases and 457 non-cancer control subjects.  Analysis of various possible associations showed that
  • Vitamin intake was associated with 30% lower risk of having breast cancer
  • Calcium intake reduced breast cancer risk by 40%
  • Higher levels of calcium and vitamin intake were related with a greater ability of DNA to repair itself
  • Calcium's relationship with a reduced breast cancer risk appeared to be dependent on the DNA's ability to repair itself, while this was not true for vitamins.
This new breast cancer research highlights the potential importance of vitamins and calcium for reducing breast cancer risk.  While the study summary did not indicate how much calcium or vitamins were being consumed, the study author indicated in a press release that the subjects were not taking 'mega-doses' of these supplements.  The U.S. National Library of Medicine is an excellent resource if you want to learn more about vitamins and other supplements

In many cases, we can get all the vitamins and minerals we need from the food we consume.  Read about my favorite cancer fighting foods in my book Fight Now: Eat & Live Proactively Against Breast Cancer at .
