Roman says that the risk of osteoporosis can be reduced by making certain lifestyle choices. which lifestyle choice could roman be referring to?

According to what Roman says about the risk of osteoporosis, I think that those certain lifestyle choises which would reduce the risk should include increasing calcium intake. While curing disease such as osteoporosis calcium intake is probably the main point of curing course. Also lowering salt intake could help in some measure, but not that much, so I think my first answer is the only correct.
