It is said that during the reign of Emperor Kangxi, there was a Shi Jing family on the edge of Zhili Shandong, who opened a noodle restaurant next to Guandao. Bad age, lack of available time. However, this place is surrounded by mountains and rivers, and the edible materials are quite miscellaneous. In addition to whole grains, there are many Shan Ye fern roots that can be ground into flour. Although the taste is not very good, it is also delicious in those years of recession, and the business of the small shop is also good. This is normal, but there are also strange places. It is the porter who stays in the shop. If he eats noodles in a small shop without noodle soup, his stomach will fall, which is quite uncomfortable. Drink a bowl of noodle soup after a meal and you will have no symptoms at all. In contrast, if all kinds of materials are cooked together in one pot, although noodles are sold, the essence of herbs will fall into the noodle soup. If the guests only eat noodles, they will be depressed and unable to digest the food. Every time Hou Jing's boss entertains guests, he tells him "to eat my noodles, you must have noodle soup". When people asked him why, they chased after "the original soup is fine and can be melted into food." Since then, tourists have also regarded this as one of the local anecdotes and spread it. Over time, it became "original soup and original food" and became the rule of pasta in northern Zhili Shandong. After that, it spread more and more widely and became a well-known phrase in China.

Nutrition viewpoint

From the point of view of nutrition, this way of eating is reasonable.

You know, the nutrients in the general food ingredient list refer to the content of raw food, and the nutrients that really enter the human body are lower than this amount, because food always loses some nutrients during storage and processing. For rice, flour and its products, water-soluble vitamins such as B vitamins, especially vitamins B 1 and B2 are mainly lost during cooking. Experiments show that 50% of water-soluble vitamins, a small amount of minerals and coenzyme helpful to digestion in boiled noodles and jiaozi will be dissolved in soup due to diffusion, so drinking soup can make up for the lost nutrients in noodles or jiaozi to some extent.

The same is true of cooking and washing rice too frequently.
