The Influence of Protein on the Prevention of Fragility Fractures Among Senior Adults Abstract. The aim of this review article is to discuss protein intake in senior adults at risk for fragility fractures as a modifiable factor for fracture prevention. Proteins are building blocks of the bone matrix and the muscles. This dual function fits in with the concept of prevention of fragility fractures in senior adults aimed at reducing both bone loss and falls. In older adults, a protein-rich diet could be another simple and effective way to promote bone and muscle health, in addition to the established recommendations for adequate vitamin D and calcium intake.
