Protein and sodium are the two major sources of calcium loss and
about 8000 mg of calcium pass through the kidney on average,
daily--of which 98% is reabsorbed.

We assess whether our bodies are in “calcium balance” by looking
at the diet as a whole and the acidity and composition of the
urine, which establishes how much calcium is lost. You might be
referencing a British Journal report that looked at calcium sulphur
rich mineral water and cow's milk.

The calcium derived from plant products is well absorbed by the
body, and researchers have found that all-vegetable diets may
actually protect against bone loss and osteoporosis.

Tofu prepared with calcium sulphate contains more than four
times the calcium of whole cow's milk. Green leafy vegetables,
seeds and nuts are good sources, and the calcium in green
vegetables such as kale, is absorbed as well or better than the
calcium from cow's milk.

Animal protein leaches calcium from the bones, and the high
protein western diet, based largely on animal products, which
contain high sulphur amino acids and actually causes
demineralization of the bones. The very high 1100 mg. RDA for
calcium in this country, is meant to offset the urinary calcium loss
caused by the typical meaty, high protein American diet.
Researchers have also reported that adults on a low-protein diet
were in calcium balance regardless of whether calcium intake was
500mg, 800mg or 1400mg a day.
