This is pretty standard, BUT we don't want stomach acid, it is the main thing that dissolves our bones and causes death, so the true goal is eat no food that causes stomach acid.
Few to none do this, so the Jimmys Spices Method has you drink 3 glasses of water after each meal, based on a Japanese doctors findings many years ago that was known as a stomach cure.
I personally drink less than a gallon of water a year, I only consume fruit juices or juises made with distilled water, but rarely will you ever catch me drink plain water. I don't believe we humans were designed to drink water.
