What are acidic food and alkaline food?

Acidic food is classified according to the popular theory of acidic constitution, rather than directly detecting pH value. That is, after food is digested, nitrogen, carbon, sulfur, chlorine, salt and so on. Eventually, acidic free radicals remain in the body, which is called acidic food. Such as: cattle, sheep, pigs, chickens, ducks, fish, grains and so on.

Acidic foods usually refer to foods rich in protein, fat and sugar. Because of its high content of sulfur (S), phosphorus (P) and chlorine (Cl), it is metabolized in human body to produce sulfuric acid, hydrochloric acid, phosphoric acid, lactic acid and other substances.

Alkaline food refers to the chemical composition of ash obtained after food combustion, which mainly contains elements such as potassium, sodium, calcium and magnesium. Dissolve in water to form alkaline solution. This kind of food includes all kinds of vegetables, fruits, beans, almonds and chestnuts in milk and hard fruits.
