How can we maintain the balance between acid and alkali in the intestinal tract in terms of diet?

The correct classification of acid and alkaline food is: Any food containing more metal elements, such as potassium, sodium, calcium, and magnesium, Which is oxidized in the body to generate an alkaline oxide with cationic, therefore, it is called "alkali food" (or alkaline food). Most fruits, vegetables, and soybeans are alkaline foods, and fruits are acidic in taste, however, after entering the human body, it is completely oxidized to carbon dioxide and water. The remaining alkaline elements need to be replaced by acidic substances in the body. Therefore, the fruit is acidic in vitro and alkaline in the body.
Any food containing metal element phosphorus, sulfur, and chlorine can generate an anionic acid root such as phosphate, sulfate, chloride and other alkaline substances in the body after oxidation in the body, therefore, it is called "sour food" (or acidic food), such as meat, fish, poultry, eggs and cereals.
Some foods have the above two conditions, but do not affect the acid and alkaline properties of the food. They also belong to "sour food", such as pure sugar and fat.

The pH of food can affect the pH of human blood. The pH of human blood should be kept between 7.35 and 7.45. If the pH is low, 7.35 or higher, blood poisoning may occur, the latter is known as alkali poisoning.
Therefore, in daily diet, we should maintain a balance between the vegetarian diet and should not eat too much sour food such as big fish and meat, nor should we eat too much food or the proportion of the vegetarian diet.
For example, if it is 4: 6 or 3: 7 And has become acidic, the intestinal garbage should be cleared. It is recommended that you use fruit and vegetable juice once a week and drink a cup of fruit juice every day.
