That's one means of the body to get rid of it.

I've read something different (but similar).
What increases acidity is meat, dairy, nuts, grains.
Virtually the only acidity lowering food items were
fruit (bu
t ripe)
and vegetables with few exceptions.
Even sour lemon reduces in the end-effect the acidity load.

I didn't read anything that decomposition of purines or fat could
reduce the blood acidity- do you have references on this?

I may again quote my only net-available reference here:

Additionally, bone mass is also dependent upon the relative
acid/alkaline dietary load (2,3).   Acid generated by the diet is
excreted in the urine and can cause calciuresis.   Meat and fish have a
high potential renal acid load (PRAL) whereas fruits and vegetables have
a negative PRAL, meaning they reduce acid excretion.   The human kidney
