Re: Try to take only whole food Vitamin C-- very important

The body does not need to rob calcium [or other alkaline minerals] from the bones to keep itself at the correct PH [balance]. The following is excerpted from http://en.wikipedia.org/wiki/Kidney:

"Homeostasis

Acid-Base Balance

The kidneys regulate the pH, mineral ion concentration, and water composition of the blood.

By exchanging hydronium ions and hydroxyl ions, the blood plasma is maintained by the kidney at pH 7.4. Urine, on the other hand, becomes either acidic at pH 5 or alkaline at pH 8.

The pH is maintained through four main protein transporters: NHE3 (a sodium-hydrogen exchanger), V-type H-ATPase (an isoform of the hydrogen ATPase), NBC1 (a sodium-bicarbonate cotransporter) and AE1 (an anion exchanger which exchanges chloride for bicarbonate). Due to the polar alignment of cells in the renal epithelia NHE3 and the H-ATPase are exposed to the lumen (which is essentially outside the body), on the apical side of the cells, and are responsible for excreting hydrogen ions (or protons). Conversely, NBC1 and AE1 are on the basolateral side of the cells, and allow bicarbonate ions to move back into the extracellular fluid and thus are returned to the blood plasma."

Just my view,

David
