For example, people say that they drink porridge when their digestive function is not good. Isn't that porridge with water? Foods with more water are easier to digest and absorb. Part of the principle is as follows:

The digestive organs of the human body can secrete various digestive juices. Eating more water (water or soup) will dilute the digestive juice. So, is it necessarily bad that the digestive juice is diluted? Not exactly. Besides chemical digestion of digestive juice, digestive tract also has important mechanical digestion. I will tell you step by step ~

In the mouth, it is saliva, the main components are water and salivary amylase, which is used to hydrolyze a small amount of starch into glucose. We can taste food because the taste buds on the tongue are stimulated by dissolved food. Note that it is dissolved food. Insoluble things are tasteless. We need water here. In addition, food needs the help of water to be cut, ground and mixed into moist and soft food balls in the mouth. Saliva alone is not enough.

The digestive juice in the stomach is gastric juice, and its main components are water, hydrochloric acid, pepsinogen, alkaline mucus and endogenous factors. It is said that water dilutes stomach acid, which leads to indigestion. In fact, if you don't drink a lot of water or alkaline water, the impact is not great. Because the PH value of gastric acid in digestive period is about 0.5, it can effectively assist the digestion of food without such a low PH value. For example, pepsin has the strongest effect when the PH value is 1.8~2.4, which means that gastric acid will be weaker if it is not diluted.

Small intestine is the most important place for digestion and absorption. It's more complicated in the small intestine. Digestive juice includes bile, pancreatic juice and small intestine juice. However, the water you eat and drink will not dilute them. Why? Because the stomach can absorb water. In other words, if a meal is too dry, it is not conducive to the digestion and absorption of the small intestine. Because too much water is lost in the stomach, in the small intestine, the chyme mass is not moist enough and the osmotic pressure is too high, which is not conducive to digestion and absorption. Enzymes in digestive juice can only work in humid environment, and intestinal mucosal cells can only absorb dissolved substances. It needs water.

Not to mention the large intestine. However, as long as the contents have not been discharged, the large intestine will absorb water indefinitely, which will eventually lead to constipation. This is beside the point.

Also talked about osmotic pressure, osmotic pressure has an important impact on all aspects of the human body. Take the digestive system as an example. If there is too little water in food, the osmotic pressure will be high. What effect will high osmotic pressure bring? It will absorb water. In other words, foods with high osmotic pressure are difficult to be digested and absorbed well, but it is possible to take water out of the body.

After talking for so long, there is only one conclusion: drink a proper amount of drinks (such as milk for breakfast, juice for any meal, boiled water, etc. ) or eating soup is good for digestion and absorption. However, drinking too much is not good.

After typing so many words, if I can help you find out the truth, I'm not typing in vain ~ haha
