How about in the food that we eat?

Explanation:

Most of the things that we eat that taste good, are slightly acidic. For instance, wine, cheese, butter, lemon juice, vinegar, egg yolk, are all slightly acidic.....#pH=5-7#. The most basic thing that we eat is quite probably egg white, #pH~=8.9-9.1#. (Note that interestingly, when an hen's egg is freshly laid it has a #pH# of #7.8-8.0#; I am told that on storage it loses (the acidic oxide) #CO_2# and #pH# rises.....the shell must be permeable to #CO_2(g)#) The soapiness and bitterness of egg-white is quite characteristic of a base.
