Is liquor acidic or alkaline? As we all know, food can be divided into two categories: alkaline food and acidic food. People must eat acid and alkali food to maintain the balance of blood acidity and alkalinity in the body, that is, PH value. The so-called acidic and alkaline foods are not identified by taste or taste, but mainly by the chemical elements contained in the food after being absorbed and oxidized by the body as the basis for identification.
