Promoting Healthy Bones
Sorting Out the Science
According to the International Osteoporosis Foundation, the incidence of hip fractures increased nearly 25% worldwide between 1990 and 2000. By 2050, the worldwide incidence of hip fracture is projected to increase by an alarming 240% in women and 310% in men. In addition, in women over 45 years of age, osteoporosis accounts for more days spent in the hospital than many other diseases including diabetes, myocardial infarction and breast cancer.
What’s causing these declines in bone health and what can be done? It's well-known that meeting recommendations for calcium and vitamin D is critical for bone health—but is this enough? Are supplements necessary? What is the role of other nutrients such as protein or beverage ingredients such as caffeine and phosphoric acid?
In this program, Dr. Robert P. Heaney, noted bone health expert and Creighton University Professor of Medicine, reviews the research related to lifestyle factors that impact bone health, including diet, supplement use and physical activity. Learn why taking a “mono-nutrient” approach when addressing bone health issues is usually wrong, as well as how clinical studies on the impact of caffeine, phosphoric acid and carbonation on calcium balance shape discussions on beverage and bone health concerns.
Cite two major factors contributing to poor bone health.
Discuss the synergy between nutrition and exercise in promoting bone health.
Explain the inadequacy of taking a "mono-nutrient" approach to bone health, using the impact of protein intake on calcium balance as an example.
Discuss clinical research findings related to the impact of caffeine, phosphoric acid and carbonation on calcium balance and bone health.
