"Many people know that porridge can nourish the stomach, and they often hear that soaking in rice hurts the stomach, but many people think that how big is the difference between soaking in rice and porridge, will it hurt the stomach? In fact, if we want to say the definition of porridge, we should say Yuan Mei, a great genius and gourmet in the Qing Dynasty. He knows how to cook porridge, and he describes it very well: "rice is not porridge when you see water;" "See rice but not water is not porridge. It will make water and rice harmonious and soft, and then it will be called porridge. " This explains the difference between soaked rice and porridge: in soaked rice, water is water and rice is rice. The two are not integrated, and the rice grains are not loose, just like rice. The rice grains of porridge completely disintegrate and disperse, and are completely compatible with water. When it comes to the digestibility of starch, we should start with starch granules. In fact, natural starch exists in the form of starch granules. Starch is not scattered, but tightly squeezed together with an outer film. After cooking with water, the rice grains swell and become sticky, but the starch grains only swell and do not disintegrate. Only after full boiling, starch particles can completely disintegrate, starch molecules run out, making water sticky and rice grains blend with water. This is porridge. Therefore, from the difficulty of digestion, porridge and rice are different. Basically, porridge does not need to be crushed by the stomach, but can be directly turned into chyme. Amylase can fully act on it, so it is easy to digest without chewing. Soaking rice is different. It has not reached the state of porridge, and it needs teeth to chew before the stomach can turn it into chyme. However, the feeling of soaking rice is similar to porridge, and it basically goes into the stomach without chewing. It is good for people with strong stomach function, but it becomes a heavy burden for people with weak stomach. Not crushed rice grains will bring more tasks to the digestive juice in the small intestine. Therefore, porridge has the function of nourishing the stomach, but soaking rice does not.
