Animal Protein Bad for Bones

March 3, 2010

Animal protein is associated with decreased bone health, according to a study in this month's British Journal of Nutrition. In Beijing, China, 757 girls with an average age of 10 years were randomly assigned to a group consuming cow's milk fortified with calcium, one consuming cow’s milk fortified with calcium and vitamin D, or a third group that served as controls and made no changes. Bone mass was measured at the beginning of the study and at 12, 24, 48, and 60 months. While calcium intake was positively associated with bone health, animal protein, especially from meat and eggs, was negatively associated with bone mineral density and content.
