[What to do to prevent osteoporosis ? Between myths and scientific reality].

Abstract

Osteoporosis is a skeletal disease characterized by low bone density and altered microarchitecture, exposing to bone fragility and an increased risk of fracture. Several therapeutic modalities can effectively reduce the risk of fractures both vertebral and non-vertebral. While a significant part of bone strength and structure is genetically determined, it should be recalled that the environment also plays a significant role in these parameters and the risk of fracture, thus offering preventive opportunities thanks to lifestyle. In this article, we review the common misconceptions and myths about the influence of diet and physical activity on bone mineral density and fracture risk.
