The truth is that there's more to bone health than density, as we know, and all of the drugs for osteoporosis have side effects that need to be considered carefully until safer drugs become available. And, in the meantime, we can try to do anything we can to stave off, or even reverse, osteoporosis wherever possible. One study I read looked at the anomaly of bone fractures and questioned what factors other than density come into play and can be improved, e.g, 'tensile strength of bone' v density. The analogy was to comparing the real strength of bamboo scaffolding (having the ability withstand shock and movement) versus the iron and concrete that cannot. To me, conceptually, the issue that bone density is only part of the story makes sense and might suggest other, future avenues for treatment beyond the current drugs.
