I recently learned that a high salt consumption interferes with calcium. In a study in Alberta it was discovered that when sodium leaves the body in the urine, it takes calcium with it. I was a salt-aholic, and have the beginning stage of osteoporosis, rapidly getting worse, despite a healthy diet, mineral supplements and anti-osteoporosis meds. It took a little while to get used to not adding salt, but I enjoy my food more now without it. My last DEXA scan showed no worsening, which can also be credited to the meds. But if I didn't need so much salt, it won't hurt to cut way back and may be really helpful if not preventative for younger people.
