Extended information: Nutritional value of sour soup: It is understood that Miao sour soup is rich in calcium, phosphorus, iron, etc., which plays an important role in maintaining the excitability of nerves and muscles and maintaining the acid-base balance of the body.

No wonder the local people say, "If you don't eat sour food for a day, you will have a lot of fun walking around (which means staggering)", which has certain scientific basis.

Not all foods with sour taste are acidic foods. Miao sour soup dishes are foods with a relatively balanced acidity and alkalinity.

First of all, the lactic acid in the Miao sour soup is produced by self-fermentation, and the lactic acid turns into water and carbon dioxide after being burned in the body. Based on this, the Miao sour soup can be considered a neutral food.

Second, sour soup is rich in calcium, iron and other alkaline components, while fish in sour soup is rich in acidic components (such as phosphorus and protein, etc.), which form acidic substances in the body and can lower the Ph value of the blood.

Third, the vegetables in the Miao sour soup food contain calcium, magnesium and other elements, which produce alkaline substances after metabolism in the body, which can prevent the blood from changing to acidity.

Therefore, Guizhou sour soup is a neutral food.
