Studies have shown that when people eat, they will first digest it in their mouths. Hard teeth are like a clever "crusher", which cuts large pieces of food into small particles, while salivary glands keep secreting saliva and tongue keeps stirring, so that food and saliva are fully mixed. Amylase in saliva can decompose starch into sweet and refreshing maltose, which is convenient for further digestion and absorption in gastrointestinal tract. At the same time, food will stimulate the taste nerve of the tongue and transmit it to the brain reflexively, so that the brain sends out a message to "inform" the stomach, intestine, pancreas and other parts to be ready to accept food. After receiving the "command", the stomach, intestine and pancreatic juice are secreted one after another, and the gastrointestinal peristalsis is enhanced, thus accelerating the digestion and absorption of food nutrition by the gastrointestinal tract.
As the saying goes, porridge nourishes the stomach, and porridge cannot be overheated. If overheating will affect the gastric mucosa, it will hurt the stomach after being stimulated, so everyone must pay attention to drinking porridge. Qualified stomach-nourishing porridge is sticky, and rice grains will not sink under water, but will be evenly dispersed by water. Moreover, some porridge is not strictly porridge, rice is rice, and water is water. The two have not yet merged, so they can only be called soaked rice. Porridge nourishes the stomach, and soaking in rice hurts the stomach.
We can learn some common sense about porridge and soup from the above. In fact, porridge is easier to digest, basically does not need to chew, and can be easily absorbed without too much work in the stomach. Moreover, soaking rice in water is easy to produce gastric acid, and rice grains are not easy to digest, so it will cause certain damage to the function of the stomach. It is better to choose porridge to soak rice.
