Noodles are a kind of health food with simple preparation, convenient eating and rich nutrition, which can be used as both staple food and fast food. Noodles are easy to digest and absorb. Noodles are rich in carbohydrates, which can provide enough heat and absorb a lot of water during cooking. 100 grams of noodles will become about 400 grams after cooking, so it can produce a strong feeling of fullness. Noodles have a long history in China. Boiled cakes in the Eastern Han Dynasty and soup cakes in the Wei and Jin Dynasties were the original names of noodles. Noodles are not only the staple food for economic satiety, but also the best food for elegance. Generally speaking, noodles with good taste contain more protein, which can supplement the nutrition needed by human body. Noodles can be eaten cold or hot, but remind everyone that too hot noodles will damage the esophagus, and too cold is not conducive to digestion and absorption, so eating a bowl of warm noodles is most conducive to nutrient absorption. In the traditional diet, there is a saying that the original soup becomes the original dish. People should drink some original soup after eating noodles, jiaozi or Yuanxiao. From the point of view of nutrition, this makes sense. When cooking starchy food, the starch on its surface will be scattered in the soup. When heated to 100℃, starch particles will be decomposed into dextrin, which can help digest food.
