Selenium-Enriched Milk May Decrease Breast Cancer Tumor Growth

19 Jan 2015 --- A recent University of Guelph study has found that dairy cows fed diets including selenium produce milk that may help reduce the progression of human breast cancer tumors.

While milk has often been coined with the tagline, ‘it does a body good,’ University of Guelph researchers have discovered another reason that statement holds true through selenium supplementation. In a recent study, scientists revealed that dairy cows fed diets including selenium produce milk that may help reduce the progression of human breast cancer tumors.

Selenium, an essential nutrient for animals and people, is a powerful antioxidant and plays a critical role in metabolism, reproductive health, DNA synthesis and the body’s natural defense system. Dietary selenium has also shown the potential to reduce the growth of mammary tumors. The organic selenium used in the study was Sel-Plex, from Alltech, a natural source of selenium enriched yeast with higher bioavailability than inorganic sources.
