Bad to the Bones: What to Avoid for Bone Health
1. Too Much Salt
The more salt you eat, the more calcium your body gets rid of, which means it’s not there to help your bones. Foods like breads, cheeses, chips, and cold cuts have some of the highest counts.
You don’t have to cut salt out entirely, but aim for less than 2,300 milligrams of sodium a day.
