Acidic food is based on the popular theory of acidic constitution, rather than the classification of foods directly tested for pH value. That is, after food is digested, nitrogen, carbon, sulfur, chlorine, salt, etc. are finally formed, and acid radicals are left in the body, which is called acidic food. Such as: cattle, sheep, pigs, chickens, ducks, fish, grains and so on.
