Sunday House Call has focused on the promising research and a greater understanding on the effects of Vitamin D. We have had principle investigators discuss its effects on reducing the rate of falls in the elderly, reducing the risk of colon and breast cancer recurrence, reduction of stress fractures in young women and its effects on retarding progression of macular degeneration. In each instance, these areas of research continue to support through evidence-based findings that vitamin D does more than help maintain bone strength and density.

According to a recent study conducted by Creighton University School of Medicine and reported in the June 8 online edition of the American Journal of Clinical Nutrition, people with inadequate levels of Vitamin D may be at risk for developing cancer.
