Animal Protein is Acidic But NOT Harmful – Part 1 (Bone Loss)

The acid-ash hypothesis tells us that whatever we eat leaves behind an acid or alkaline ash that contributes to our overall pH.


When we eat a diet that’s predominantly acid-forming our body must add a ‘base’ to neutralize the environment. It’s often thought that this neutralizer is calcium, and suggested that bone is used to fulfill the requirement.

This theory holds true in the sense that there are remnants (acid/ash) left behind after the metabolism of food, but many fail to recognize the important role that kidney’s play in regulating pH. Bicarbonate ions, found in the blood, are perfectly capable of buffering the acid left behind from the metabolism of an acidic food.  Meaning, our body is perfectly capable of maintaining a pH balance without using calcium.

Calcium metabolism remains unaffected by higher acid levels in the diet. 

Although grains and beans are just as acidic, animal protein seems to be the only food scrutinized for its acidity and accused of causing bone loss. Which is surprising, as meat is the only acidic food that improves calcium absorption, and decreases our risk of fracture and osteoporosis. Protein is an acid-forming food, but it increases the body’s ability to excrete acid, and absorb calcium.

There may be additional calcium in the urine while eating a higher protein diet, but it’s not from bone.

Perhaps if the majority of the population knew how uncommon acidosis was in healthy individuals, they would stop assuming that eating 1 extra piece of meat per day will send them into full blown acid-overload and strip their bones of calcium…
