High phosphorus consumption has been linked to osteoporosis because it promotes the
excretion of calcium from the bones.

calcium retention was measured in 14 women by using an isotope to measure the
excretion of 41Ca to measure bone loss.

The results suggest that the SNP may be contributing to increased
calcium excretion in urine, a major risk factor for kidney stones and also a sign
of bone loss.

Oral supplementation with
calcium - D - glucarate has been shown to inhibit beta - glucuronidase, an enzyme produced by colonic microflora (e.g., E.coli) that is capable
of hydrolyzing glucuronide conjugates, thus returning estrogen readied for
excretion back into circulation.
It causes urinary
excretion of calcium, magnesium and potassium and thus affects brain metabolism.
The fallacy
of most other studies linking sulfur - rich animal foods to high
calcium excretion is equally easy to find.

excretion of common, mild environmental exposures
of mercury, arsenic, cadmium, lead and tin without altering
excretion of other minerals, including
calcium, magnesium, iron, copper and selenium.
But no, even though the acid load was neutralized, there was still [this] excess urinary
calcium, consistent with the radioactive isotope study, «challenging the long - standing dogma that animal protein consumption results in an acidosis that promotes the [excess]
excretion of calcium...»
It has been shown that small amounts
of aluminum - containing antacids increase the urinary and fecal
excretion of calcium, inhibit absorption
of fluoride, and inhibit absorption
of phosphorus, creating a negative
calcium balance.
The third claim, however, is addressed at length in the scientific literature, and if you just do a cursory search, you can find studies that support this idea that consuming acid - forming foods will lead to excess
calcium excretion in the urine, and it's easy to come to the conclusion that acid - forming foods — which would be animal products, among other things — are negative for bone health because
of that.
Her professors or instructors are saying that high dietary protein increases urinary
calcium excretion, and then they make the assumption that, therefore, it's bad for bone health, but that's only part
of the puzzle, and they're not understanding the increase in intestinal absorption
of calcium that animal protein and protein in general leads to.
A study published in the British Journal
of Nutrition found that when women drank 1/2 to 1 liter
of grapefruit, apple or orange juice daily, their urinary pH value and citric acid
excretion increased, significantly dropping their risk
of forming
calcium oxalate stones.
A reduction in animal protein reduces the production
of acids within the body and appears to limit the
excretion of urate — uric acid crystals that can act as seeds to form
calcium stones or create entire stones themselves.
Effect
of short - term high dietary
calcium intake on 24 - h energy expenditure, fat oxidation, and fecal fat
excretion
The old thinking would predict that then there would be no
calcium loss since there is no excess acid to buffer, but no, even though the acid load was neutralized there was still the excess urinary
calcium, consistent with the radioactive isotope study, «challenging the long - standing dogma that animal protein consumption results in an acidosis that promotes the increased
excretion of calcium....
A reduction in animal protein should also limit the
excretion of urate — uric acid crystals that can act as a seed to form
calcium stones, or can create entire stones themselves.
An observation linking phytate consumption with good bone health is much more likely to be a result
of the participants adapting to their high - phytate diet via lessening their
calcium excretion — just because phytates chelate some
of the nutrients doesn't mean that a high - phytate diet can't be better for bone health than a terrible low - phytate diet (think refined grains, poor fats, low
calcium, low vitamin D, and so on).
Vitamin K — This essential vitamin is particularly important to bone health and the prevention
of osteoporosis, as it limits the body's
excretion of calcium and increases
calcium absorption.
This pattern
of findings can potentially be explained by the high fiber content
of these two diets, which may have impeded
calcium absorption.22 Nonetheless, the substantial increase in urinary phosphorus
excretion with the combination diet suggests that the subjects in this group did consume more dairy products than the other participants.
It was initially thought that high - protein diets may result in a negative
calcium balance (when the sum
of urinary and fecal
calcium excretion becomes greater than
calcium intake) and thus increase bone loss (11).
Do the mechanisms for absorption
of zinc
calcium copper and iron (which all show increased
excretion compared for high PUFA than sat fat - see last link) and magnesium share common ground, and would you expect any degree
of synergy in absorption.
In the kidneys, PTH stimulates the conversion
of vitamin D into its active form (1,25 - dihydroxyvitamin D; calcitriol), which rapidly decreases urinary
excretion of calcium but increases urinary
excretion of phosphorus.

of the increased
