                    As women age, a common problem they face is thinning of the 
                    bones - also called osteoporosis. Bone mineral density, or 
                    BMD, is a measure of bone strength related to fracture risk 
                    and the weight-bearing capacity of the skeleton. Eating calcium 
                    is recommended to maintain bone strength; are there other 
                    nutrients women need for strong bones?  
                                    
 
To determine the association between total, animal, and vegetable 
                    protein consumption in those 55 years or older, the authors 
                    of a recent study in the American Journal of Epidemiology 
                     administered a diet questionnaire to almost 600 women 
                    and 400 men. These individuals, all residents of the Rancho 
                    Bernardo senior living community in California, were also 
                    examined to determine bone density initially and four years 
                    later.  
                   For 
                    women, eating higher amounts of animal protein (e.g., meat, 
                    fish, eggs, and dairy products) was related to increased bone 
                    density. The added bone strength from consuming more animal 
                    protein was more dramatic in women who had less calcium in 
                    their diets. In both men and women, eating more vegetable 
                    protein (e.g., soy or beans and rice) was linked to lower 
                    bone density, however.  
                  This information does not imply that you shouldn't be a vegetarian 
                    or eat soy products. The study does suggest, however, that 
                    if you don't regularly eat meat, be sure to eat enough protein 
                    and include additional calcium in your diet. Protein is by 
                    itself a critical component of bones, making up a quarter 
                    of their total mass and roughly half of their volume.
