Reducing sodium may benefit bone health
We’ve known for years that excessive sodium intake contributes to hypertension, and substantial evidence links high sodium intake to increased risk of stroke and overall cardiovascular disease. Salt consumption is also associated with an increase in calcium loss, and there is evidence that suggests that reducing sodium intake could benefit bone health.
Western diets, generally high in animal protein, produce an acid load in the body, forcing the body to buffer this acid in part by the release of calcium-containing salts from bone; this is associated with urinary calcium loss and is thought to contribute to osteoporosis. Fruits, vegetables, and legumes have favorable effects on acid-base balance, since the acid-forming effect of their protein content, which is lower than that of animal products anyway, are balanced by their rich mineral content.For the complete article see the 05-15-2013 issue.
