High-Protein Meat Diet Puts Older Women At Greater Risk For Osteoporosis

July 6, 2010: 03:50 PM EST

Overweight, postmenopausal women whose diet program includes meat-based protein may lose weight, but they also lose bone mineral density faster than women who consume normal protein diets that do not contain any meats, according to a new U.S. study. The finding is important because the age group studied is especially susceptible to osteoporosis. Two controlled diet studies were conducted. In each study, women limited their caloric intake each day and obtained their protein either from a variety of lean meats or solely from vegetarian, dairy and egg sources. All groups in both studies lost weight. But those who ate the higher-protein meat-containing diets lost significant amounts of bone mineral density compared to the control group.
