Nutrition & Bone Health: Selective Literature Review

"A generalization from the literature, without a formal metaanalysis, may be that we need adequate supplies of both vitamin D and calcium to obtain significant reductions in nonvertebral fractures (especially hip fractures), and that those effects may be seen only in those persons who have insufficient vitamin D or calcium (or both). In addition, persons need to consume an overall healthful diet that meets all nutrient requirements. Protein for fracture prevention and healing and plenty of fruit and vegetables for overall health are of particular importance. A well-rounded diet is important, and evaluation of one element or vitamin does not give the whole story. [emphasis added.]

So where does that leave clinicians? The best public health recommendation would be that people should consume an overall healthful diet including adequate consumption of both calcium and vitamin D. This meta-analysis highlights the importance of not  segmenting nutrition into heterogeneous populations and isolated nutrients. Bone is not just calcium, and calcium does not function in isolation.

Because of my practice area (neuroscience), I've been focused on brains and neglecting bones -- at least in terms of the evidence for best practice. Collecting these resources wasn't too difficult (thank you, OVIDSP databases and Google Scholar) and reading them has been very interesting, informative and even surprising. I hope you find some of these resources helpful, too.

In my next post (currently in draft stage) I'll be sharing evidence and practical guidelines on how a plant-based diet can build and maintain healthy bones.
