The correct classification of acid-alkaline foods is: Any food containing more metal elements potassium, sodium, calcium, and magnesium is called "alkaline food" (or alkaline food) because it oxidizes in the body to form cationic alkaline oxides, so it is called "alkaline food" (or alkaline food). Most fruits, vegetables, soybeans, etc. are alkaline foods. Fruits are acidic in taste, but after entering the human body, they are completely oxidized into carbon dioxide and water. The remaining alkaline elements require the acidic substances in the body to neutralize, so the fruit is acidic in the body and alkaline in the body.
Any food containing metal elements phosphorus, sulfur, and chlorine can generate anionic acid roots such as phosphate, sulfate, chloride ions, etc. after oxidation in the body, which requires alkaline substances in the body to be removed, so it is called "acid food" (or acid food), such as meat, fish, poultry, eggs and grains.
Some foods meet the above two conditions, but do not affect the acidity and alkalinity of the food, and are also "acid-forming foods", such as pure sugar and fat.
The pH of food can affect the pH of the human body. The pH of the human body should be kept between 7.35-7.45. If the pH is lower than 7.35 or higher than 7.45, blood poisoning will occur. The former is called acidosis and the latter is called alkali poisoning.
Therefore, in daily diet, we should maintain a balance between meat and vegetables. We should not eat too much fish and meat to make sour foods, nor should we eat too much vegetarian food. The proportion of meat and vegetables should not be too much.
It is 4:6 or 3:7. It has become acidic and should be cleaned up intestinal garbage. It is recommended to use fruit and vegetable juice once a week, and you can drink one glass of juice every day.
