In China's dietary tradition, there has always been a saying that "the original soup turns into the original food". The old man wants some original soup with jiaozi after eating noodles. Li Peiwen, chief physician of Chinese medicine oncology department of China-Japan Friendship Hospital of the Ministry of Health, and Li Changping, deputy director of nutrition department of the Third Hospital of Beijing Medical University, said in an interview with the reporter of Life Times that the statement that "the original soup becomes the original grain" is reasonable from the perspective of nutrition.

"Hua" has two meanings.

First of all, "transformation" means "digestion". Director Li Peiwen said that when cooking starchy food, the starch on its surface will be dispersed into the soup. When heated to 100℃, starch particles will be decomposed into dextrin, which can help digest food. Moreover, the noodle soup also contains digestive enzymes, which will not be destroyed during cooking and can help digest food. Therefore, drinking the original soup helps to reduce food accumulation. The short story mentioned above is actually because Lamian Noodles in the northwest is hard and difficult to digest, which leads to intestinal obstruction. After drinking the soup, the original soup helps the noodles digest, so the intestines wriggle again.

Secondly, drinking the original soup has a certain supplementary effect. Director Li Changping said that flour is rich in water-soluble B vitamins, but in the cooking process, B vitamins will be lost to the soup. It is reported that the water-soluble vitamins dissolved in soup can account for 50% of the original food, so drinking soup can make up for the vitamins lost in pasta cooking to some extent. Similarly, some areas are used to cooking with "fishing rice", which will also cause the loss of water-soluble vitamins, especially B vitamins. So we advocate "steamed rice". If we cook with fishing rice, we should drink rice soup.

Water-soluble vitamins in food are easily lost during processing and cooking. The principle advocated at ordinary times is not to use hot water for rice washing, not to wash rice excessively, to control the number of rice washing within two times, and not to add too much water for cooking, in order to avoid the loss of water-soluble vitamins, especially B vitamins. The reason is exactly the same as the original soup.

What kind of soup can melt the original food?

Director Li Peiwen said that "original dish" refers to starchy food, and "original soup" refers to the water used to cook these foods. For example, cooking jiaozi, noodles, wonton, dumpling soup and rice soup. Hot pot soup can't be compared, because there will be a lot of oil dissolved when you rinse meat, which leads to high oil content in hot pot soup, which is harmful to your health if you drink it for a long time.

Also, we must pay attention to the "original soup" to melt the original food. Li Peiwen, the director, said that Xi's famous mutton steamed buns used stewed mutton soup, and then steamed buns were soaked in it. This soup is not the original soup of steamed stuffed bun, so it has no above effect.

Drink soup before meals to lose weight, and your stomach is not good after meals.

The original soup has so many benefits, so when is the best time to drink it? Li Changping said that in theory, most people drink porridge after meals, just like everyone likes to drink porridge after meals, and there is no strict limit on the amount. Director Li Peiwen said that it is not easy to feel full when eating pasta, so it is easy to eat more and more. Therefore, obese people should drink it before meals, which can make people feel full to a certain extent, slow down the eating speed and avoid overeating. This is also the reason why the proverb "drink soup before meals, slim and healthy" is popular among the people. However, patients with chronic atrophic gastritis have less gastric acid secretion. Drinking soup before meals will dilute gastric juice and further affect the digestion of food, so don't drink too much soup before meals.
