Trabecular architecture is altered, cortical thickness (Cortical Th.) de-
creases, and bone strength is compromised (27,30). To deter-
mine whether the loss of bone with aging can be prevented and
whether bone that has already been lost in aged mice can be
replaced, we fed adult and old male mice either a normal diet or
diets supplemented with DP for 6 mo. Bone mass and structure
were examined before, during, and after dietary supplementation.
