Unfortunately, this has resulted in a dramatic decrease in the amount of Vitamin D that our bodies produce. Now, we don’t need to have vitamin D just to eliminate rickets, it turns out that vitamin D is used by the body for lots of other critical functions.
Studies have produced evidence that low levels of vitamin D make:
- Men more likely to have heart attacks.
- Breast and colon cancer victims less likely to survive.
- Kidney disease victims more likely to die.
- Children more likely to develop diabetes.
Two other studies suggested that higher vitamin D levels reduce the risk of dying prematurely from any cause.
What to do? We’ll discuss how to address this problem effectively in a day or so.
