High Salt Intake Appears to Increase Bone Resorption in Postmenopausal Women but High Potassium Intake Ameliorates this Adverse Effect

A high-salt diet increases urinary calcium excretion. Its effect on bone, however, is less clear. Recent research suggests that a high-salt diet increases the rate of bone resorption in postmenopausal women over a 4-week period, but increased potassium intake (as potassium citrate) ameliorates this adverse effect. These findings may have implications for the development of dietary guidelines for osteoporosis prevention.
