Describe what is known about the relationship between protein intakes (both low and high) and bone health
The mineral crystals of bone form on a protein matrix—collagen. Restoring protein sources to a low-protein diet can often improve bone status and reduce the incidence of hip fractures even in the elderly. However, a diet lacking protein no doubt also lacks energy and other critical bone nutrients, so restoring a nutritious diet overall may be of highest importance. An opposite possibility, that a high-protein diet causes bone loss, has also been explored, but study results are inconsistent. Excess dietary protein causes urinary calcium losses, but a diet also high in fruits and vegetables may oppose this effect, producing no net calcium loss from bone.
