This hormone increases
calcium excretion in urine.
Feeding protein to subjects resulted in increased
calcium excretion in the urine.
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.
In addition, caffeine causes an increase in
calcium excretion in the urine.
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.
Not exact matches

in urinary
calcium excretion.

excretion following uptake of excess amounts of monophosphates
in the form of
calcium and potassium monophosphates, respectively.
Excess caffeine, dietary fat, dietary fibre and high - protein diets can lead to
in high
calcium excretion.
In the WHO model to calculate
calcium requirements,
calcium excretion increases with higher animal protein and / or higher salt intake.
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...»
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.
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....
Well, it's uncontroversial that protein results
in greater
calcium excretion, but we've just been assuming it's coming from the bone — I mean where else could the extra
calcium dumped
in our urine be coming from but from our bones?
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.
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.
Urinary
calcium excretion decreased
in the control and fruits - and - vegetables groups.
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.
When this is detected the body not only is there an increase
in bone building cells, but there also an increase
in calcium uptake accompanied by a decrease
in calcium excretion.;
Lowering dietary protein to U.S. Recommended dietary allowance levels reduces urinary
calcium excretion and bone resorption
in young women.
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.
Because of the increased
calcium excretion brought on by furosemide (i.e. an increase
in urinary
calcium levels), there could be a problem using this medication
in patients with a history of
calcium oxalate bladder stone formation.
The largest coral reef
in the Western Hemisphere, the Belize Barrier Reef is home to half a dozen of coral species, tiny creatures whose
calcium excretions form the backbone of this unique biosphere.
