absorption, retention and excretion is likewise governed
by complex feedback mechanisms involving other nutrients and hormonal signals.

Then they have another figure on the right that shows that as you increase protein
by that same amount, there's a corresponding increase in the amount of

intestinal calcium absorption compensates for any loss of
calcium that might happen in the urine, and the overall
calcium balance either doesn't change or it actually even goes up with higher - protein diets.

absorption of vitamin B12 [91 - 93], possibly through alterations in
