Potassium-rich foods can help offset high salt diet contribution to osteoporosis.

Eating potassium-richfoods such as bananas tomatoes and orange juice can help preventosteoporosis for postmenopausal women by decreasing calcium losses, accordingto a UCSF study. In postmenopausal women the consumption of excessive salt hasbeen shown to increase the level of bone minerals excreted through urine,although salt does not seem to effect younger women or men in a similarfashion, said study author Deborah Sellmeyer, MD, UCSF assistant adjunctprofessor of endocrinology and metabolism. While the benefits of dietarycalcium and vitamin D for preserving bone density have long been established,the UCSF study is the first to examine the role of potassium in preventing bonedensity loss exacerbated by a high-salt diet.
Nsteoporosis affects anestimated 44 million Americans, mostly women. Although no studies have directlymeasured the level of dietary salt necessary to adversely affect bone mineralexcretion, Americans eat twice as much salt (sodium chloride) as they should,according to the National Institutes of Health (NIH). The NIH recommendsconsumption
In the UCSF study, 60healthy postmenopausal women were placed on a low salt diet (two grams / day)for an initial three weeks while their level of excreted calcium was measured. Thelevel of excreted NTX, a bone protein, was also measured. A higher NTX levelindicates that more bone is being broken down, or reabsorbed, leaving women atincreased risk for fractures.
