Acid/Alkaline Diet?
From Respectful
Insolence:
"The bottom line is that, in the absence of renal and lung
disease, the homeostatic mechanisms controlling the pH of your blood
are incredibly robust and tightly regulated.
(One reason dialysis
patients become acidotic is because their kidneys can no longer
regulate bicarbonate concentration in the blood.) It's very hard to
alter your blood pH by very much for very long, although you can
change it briefly (for example, hyperventilation will cause a
transient and sometimes quite impressive alkalosis).
Indeed, when
these homeostatic mechanisms fail, the resulting acidosis or alkalosis
is caused by this failure. Trying to reverse an acid-base disturbance
is not usually possible without reversing the underlying cause. It
won't matter how much alkali you administer; without reversing the
underlying cause, the acidosis will return as soon as you stop giving
it. In fact, if a patient receives an intravenous bicarbonate infusion
to alkalinize the urine, blood pH will change little, unless you
infuse a dangerously high amount.
The kidney excretes the extra
bicarbonate (the intended effect), and hypoventilation shifts the
balance from bicarbonate to carbonic acid. Funny that alties, who so
decry "conventional medicine" for treating the symptoms,
rather than the "underlying causes" of disease would fall
prey to such the same mistake they accuse us conventional doctors of.
(No it isn't.)
Oh, there are a few indications for alkalinization of
the urine, like the treatment of certain kinds of kidney
stones, but these indications are pretty few."
