Calcium, body mass affect bone health
Researchers at the University of Tennessee report that adequate calcium intake, lean body mass and physical activity are the three most important factors in maintaining healthy bone mineral density (BMD) and bone mineral content (BMC)—both factors in determining...
Seniors need calcium for bones and heart
