That isn't to discount calcium and vitamin D. Calcium plays a role in strong bones (as your body's most abundant mineral, 99 percent exists in your bones and teeth), and vitamin D helps your small
intestine absorb that calcium.

Even though plant foods, especially green leafy vegetables, are high in oxalates, in a normal person the oxalates are poorly
absorbed, because in the
intestine almost all of this substance is in the insoluble form of
calcium oxalate.67 Fats from meat or any other source will assist the absorption of oxalates by forming so - called «soap complexes» with the
calcium found in the
calcium oxalate present in foods.
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
calcium that's
absorbed in the
intestine into the bloodstream, and that increase in 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.
If you, by chance, also take hormone D supplements, those cause more
calcium to be

absorbing calcium thus causing an increase in PTH, would it also cause hypercalcemia?
It turns out that absorption of magnesium from our
intestine depends not only on the amount of magnesium that is present but also on the amount of
calcium that is present, because the cells lining our
intestine have a single spot (called the CaSR receptor) for
absorbing these minerals.
As a result, the
calcium and phosphorus are
absorbed quickly into the
intestine.
Dr Billinghurst also says that adult dogs need less
calcium and, as long as you're feeding a raw diet with raw meaty bones, the adult dog's body will

intestines.
