Similar to the rest of the world, Taiwan has inevitably entered into an era of aging society. The contemporary trends of physical therapy practice are independent private practice and being engaged in community health promotion services. As such, physical therapists are in the front line facing challenges of providing health consultation to people dwelling in the community and providing holistic health care to the aging population. Osteoporosis is a major health problem in the aging population. Bone health and exercise are most important topics for community physical therapists when delivering community health education programs. Bone health is influenced by genetic and environmental factors; the latter includes physical activity and nutrition. Having basic knowledge of nutrition related to bone health could enhance the ability of physical therapists to provide holistic care and health promotion to the aging population. This paper reviews the topics of nutrients related to bone health. Protein, polyunsaturated fatty acids, complex carbohydrates, calcium, phosphorus, fluorine, manganese, copper, vitamin B complex, vitamin C, vitamin D, vitamin E and vitamin K have positive influences on bone health. Fat, glucose, sucrose and sodium have negative influences on bone health. Excessive vitamin A, as well as insufficient vitamin A, may be associated with compromised bone health. Many nutrients, not just vitamin D and calcium, are associated with bone health. Adequate and balanced nutritional status is critical to the development and maintenance of a healthy skeletal system. In addition to having the expertise in exercises, having knowledge about nutrition for bone health could enhance the competency of physical therapies to provide holistic health care to the community.
