ARGUMENT
7" Typically, as people age, their bone mass decreases, making them
more vulnerable to bone fractures. A recent study concludes that the most
effective way to reduce the risk of fractures in later life is to take twice
the recommended dose of vitamin D and calcium daily. The three-year study
followed a group of French women in their eighties who were nursing-home
residents. The women were given daily supplements of twice the recommended
dose of vitamin D and calcium. In addition, the women participated in a light
weightlifting program. After three years, these women showed a much lower
rate of hip fractures than is average for their age.
