pH Balance Acidity / Alkalinity
The weight of the evidence is clear: the acid-load of the diet has no effect on bone health in healthy people. The body’s pH is maintained in a narrow range, regardless of the food you eat.

If there is a problem with acid load, it’s only in people with renal insufficiency. Outright kidney failure can obviously cause metabolic acidosis, and it’s possible that gradually declining kidney function results in problematic low-level acidity. Kidney function certainly tends to decline with age, while the risk of fractures increases. Despite that weak connection between old age and renal insufficiency, seniors who eat more protein still have better bone calcium retention and absorption.
How it Works
basic respiration – breathing. The lungs monitor the pH of our blood, prompting faster breathing when acidity needs to drop and slower, deeper breathing when acidity needs to rise. By exhaling carbon dioxide, we expel excess acidity. This is the primary way we compensate for fluctuations in pH.
When acidity is high, the kidneys excrete more acids and produce bicarbonate, which returns to the blood as a buffering agent. Buffering agents combine with acids in the blood to neutralize them for easier excretion.
As long as your kidneys and lungs are working, the foods you eat will neither lower nor raise the acidity of your blood. What about those urine sticks that measure pH? Altering urinary pH with the food you eat is easy enough, but it doesn’t reflect blood pH. In fact, “acidifying” one’s urine by eating “too much” meat is proof that your kidneys are doing their job and excreting excess acid from the blood.
studies consistently show that eating protein also increases the amount of calcium we absorb. This is at least partially due to specific amino acids within the protein. At any rate, with more calcium available to the body, more will be excreted.
Studies consistently show that eating protein has no effect on bone resorption (calcium leaching),
By providing ammonia substrates, protein actually increases the kidney’s capacity to do its job and excrete acids.
In truth, dairy is good for bone health. Maybe it’s the phosphate, which has been shown to reduce calcium excretion in the urine and improve calcium balance in the body. Or it could be the vitamin K2, a vital bone nutrient
a diet high in meat and other acid-forming foods increases calcium absorption and excretion while lowering parathyroid hormone (a hormone usually elevated in osteoporosis).
from comments: Otto Heinrich Warburg.He showed that cancer causes acidity, not the other way around.

Warburg Effect
Good summary: (in comments section of semi-related site)
Nescio January 2, 2010 at 12:49 amAs I understand this, tumors are often encapsulated and have a poor blood supply. This can lead to low levels of oxygen, which lead to anaerobic respiration, this and the poor blood supply lead to a relatively acidic environment within the tumor (though intracellular and extracellular pH may be different). But this is not only a characteristic of cancer cells, normal cells that are starved of oxygen behave in the same way (as in the acidosis seen after strenuous exercise), though some cancer cells will not return to aerobic respiration even when supplied with adequate oxygen (the Warburg Effect). Recent research suggests that cancer cells may prefer anaerobic repiration due to changes in their mitocondria. Neither normal nor cancer cells like extremes of pH, and alkaline conditions that will kill cancer cells will also kill normal cells.
When cancer has started interfering with essential functions of the body, as with any serious illness, systemic acidosis is quite common, because the mechanisms that normally control pH have started to fail and sometimes because more acid than these mechanisms can cope with is being produced.
I like to use the analogy of a car engine, with heat representing acid. Overheating in a car engine can result from a failure in the cooling mechanisms, such as a leak in the radiator, or the fan belt breaking, or by the engine producing more heat than the cooling mechanisms can cope with, such as an oil leak. Similarly acidosis can occur when the mechanisms that get rid of excess acidity fail, for example kidney disease where hydrogen ions cannot be effectively excreted, or emphysema where carbon dioxide cannot be effectively exhaled, or when the body produces more acidity than these mechanisms can cope with, for example diabetic ketoacidosis or salicylate overdose. Trying to treat cancer with sodium bicarbonate seems to me to be analogous to trying to deal with an oil leak by putting ice in the car radiator.
What I am trying to say is that acid conditions inside a tumor, and systemic acidosis in cancer are results of the cancer, not causes. A misunderstanding of this seems to be what is behind the beliefs that acidity causes cancer (and other diseases), and alkalinity can cure it.
As I understand this, tumors are often encapsulated and have a poor blood supply.
They are not encapsulated, but it is true that the blood supply is somewhat poor.
….(though intracellular and extracellular pH may be different)
They are. Intracellular pH is similar to that in normal cells, whereas extracellular pH is slightly lower. The cancer cells need to maintain a normal intracellular pH to avoid cellular death.This is acomplished through transport systems in the cancer cell membranes, that assist in extrusion of excess intracellular acid. So you are absolutely correct in your statement that the lower extracellular pH is a result of the cancer.
Tumors are never encapsulated?
One should always be cautious about saying never, but infiltrative growth is a very important characteristic of cancer. This powerpoint-presentation: http://www.medicalschoolpathology.com/powerpoints/Ch7-Neoplasm.pptillustrates it nicely. Try to scroll down to slides 33 and 34. They show two breast tumors, one encapsulated which is benign, and one non-encapsulated infiltrative growing which is malignant. Also slide 40 summarizes some of the characteristics of benign and malignant tumors.
the Warburg effect is misunderstood by many alt medders. To recapitulate: The warburg effect is the phenomenon that cells can degrade glucose by glycolysis only – even when oxygen is available for carrying the products of glycolysis through citric acid cycle and oxidative phosphorylation. This is prominent in many cancers. The slightly acidic microenvironment of the tumours is a result of this – Not a prerequisite for survival of the cancers. We have discussed glucose metabolism in cancers in further details here.
