On the one hand, soaking rice in soup reduces the frequency of chewing, and in the process of chewing, certain enzymes (that is, part of digestive juice) are secreted to digest food. Soaking rice in soup will reduce the digestion of food by this enzyme, which will be directly digested by the stomach, increase the burden on the stomach and make it difficult to digest things completely.

On the other hand, soaking rice in soup will increase food intake. If it is just rice, it may be reduced to half of its original weight after chewing, but it is still so much after adding soup, which invisibly increases the weight and increases the extrusion on the stomach wall. Therefore, it is generally not recommended to eat soaked rice.
