Effect of dietary phosphorus on calcium metabolism in intact and parathyroidectomized adult rats
GH Anderson, HH Draper - The Journal of Nutrition, 1972 - Elsevier
Two levels of dietary phosphorus, 0.6% and 1.2%, were compared with respect to their effect
on bone resorption and calcium metabolism in intact and parathyroidectomized (PTX) rats
fed a diet containing 1.2% Ca. Intact rats fed the 1.2% P diet for 34 weeks experienced a
greater loss of 45 Ca from the skeleton and of calcium, phosphorus and organic matter from
the femurs. These effects were not seen in PTX animals. There was no difference in the
absorption of calcium from the two diets. This study indicates that excess dietary phosphorus …
