High salt diet increases osteoporosis risk

It is well known that a high salt diet may lead to high blood pressure which is a major risk factor for stroke, heart diseases and kidney diseases. Recently, medical researchers at the University of Alberta discovered an important link between sodium and calcium. These two minerals appear to be regulated by the same molecule in the body. When sodium intake becomes too high, the body will get rid of  the sodium via the urine, taking calcium with it, which depletes calcium stores in the body. This finding is very significant since the consumption of high sodium food is nowadays very high. In fact, it is estimated that Canadians one year of age and older eat an average of about 3400 mg/day of sodium. This number is more than twice the recommended  Adequate Intake (AI) of 1500 mg/day for individuals from 9 to 70 years.

High levels of calcium in the urine lead to the development of kidney stones, and deficient levels of calcium in the body lead to thin bones and osteoporosis. This fact, reinforce that people should watch their daily sodium intake.
