Can you explain how taking an acid makes your blood less acidic?
I don't know exactly. I shouldn't have been so confident in saying lime juice or citric acid makes the blood less acidic.
My reason for stating this, is anecdotal.
Maybe it's something to do with the idea that two negatives can make a positive. And, that a positive and negative can cancel themselves. The stomach acid with citric acid, maybe, has a positive outcome.
It's interesting when a bit too much chlorine is added to a hot tub it will make the water acidic, yet it seems difficult to make the water alkaline without adding very much sodium carbonate. Even acid rain is a thing but seemingly not alkaline rain. And, average soil PH seems to be acidic more than alkaline.
If the blood cannot fluctuate in PH much without deadly effects, and the body must do all it can, to keep this PH within a small margin. Maybe like other things, the blood has a natural tendency to go slightly acidic, than slightly alkaline.
So, the body is more often doing what it can to bring up the PH, and consuming anything with a less acidifying effect, takes less toll on the body's resources. As if in situations where the blood is too acidic, it dissolves calcium from the bones, to neutralize itself.
As one of the articles links Serf Life posted here, had mentioned proponents of the alkaline diet say, osteoporosis being caused by loss of calcium in the urine.
