Diets High in Salt Could Deplete Calcium in the Body

Date: 25.7.2012 

When sodium leaves a body, it takes calcium along with it, creating risk for kidney stones and osteoporosis.

Principal investigator Todd Alexander and his team recently discovered an important link between sodium and calcium. These both appear to be regulated by the same molecule in the body. When sodium intake becomes too high, the body gets rid of sodium via the urine, taking calcium with it, which depletes calcium stores in the body. High levels of calcium in the urine lead to the development of kidney stones, while inadequate levels of calcium in the body lead to thin bones and osteoporosis.

"When the body tries to get rid of sodium via the urine, our findings suggest the body also gets rid of calcium at the same time," says Alexander, a Faculty of Medicine & Dentistry researcher whose findings were recently published in the peer-reviewed journal American Journal of Physiology -- Renal Physiology.
