Purdue study finds dairy better for bones than calcium carbonate |
|
WEST LAFAYETTE, Ind. - A Purdue University study shows dairy has an advantage over calcium carbonate in promoting bone growth and strength. |
Connie Weaver, distinguished
professor and head of the food and nutrition department, found that the bones of
rats fed nonfat dry milk were longer, wider, more dense and stronger than those
of rats fed a diet with calcium carbonate. Calcium carbonate is the most common
form of calcium used in calcium-fortified foods and supplements. Weaver said the study,
funded by the National Dairy Council, is the first direct comparison of bone
properties between calcium from supplements and milk. It will be published in
the August print issue of the Journal of Bone and Mineral Research and
