Unexpected observations were a prominent reduction
in urinary calcium excretion from the run - in to the intervention phase with the fruits - and - vegetables diet and no increase in calcium excretion with the combination diet.
(6) Again, evidence on this topic is mixed, but it has been demonstrated that excess sodium intake is associated with increased urinary excretion of sodium and calcium, and subjects who consumed the highest levels of sodium tended to have the

The effects of a two - year randomised controlled trial of whey protein supplementation on bone structure, IGF - I and
urinary calcium excretion in older postmenopausal women.
Calcitonin inhibits PTH secretion, decreases both bone resorption and intestinal calcium absorption, and increases
urinary calcium excretion (Figure 1).
