The Saltshaker Thief
Before reaching for the saltshaker, consider that excessive dietary salt not only burdens the kidneys and increases the risk of hypertension; it may also deplete vital calcium. Research by Canadian medical researchers at the University of Alberta recently discovered an important link between sodium and calcium, which appear to be regulated by the same molecule in the body. When sodium intake becomes too high, the body excretes it via urine, taking calcium with it and creating a risk for developing kidney stones and osteoporosis. So, pass the pepper instead.
