Why do you always have diarrhea when drinking pure milk recently?

Reason: That's because some people lack enough lactase to break down lactose in milk. Milk is the first choice of nutritious food, but some people will have bowel sounds, abdominal pain and even diarrhea after drinking milk, mainly because milk contains lactose. The catabolism of lactose in the body needs the participation of lactase. Some people are unable to digest lactose in the intestines due to the lack of lactase in the body, which causes bowel sounds, abdominal pain and even diarrhea, which is called "lactose intolerance" in medicine.

Solution:

1. First, limit the intake of lactose in one day. Experiments show that lactose intolerance will only occur when the intake of lactose reaches a certain level, so drinking a small amount of milk many times can avoid lactose intolerance to some extent.

2. People who are lactose intolerant can use yogurt instead of fresh milk, because the lactose in yogurt has been decomposed, but it still retains the nutrients in milk, so yogurt is a good substitute for fresh milk; In addition, adding lactase to milk before drinking fresh milk will decompose lactose in fresh milk before drinking, and lactose intolerance will not occur. In order to alleviate the symptoms of lactose intolerance, you can also drink a small amount of milk many times to reduce the amount of lactose you enter at one time and relieve gastrointestinal discomfort. You can also drink milk after meals to prolong the residence time of milk in the gastrointestinal tract, so that lactase can fully react with milk in the intestine and decompose lactose.

3. Diarrhea after drinking milk can be changed to yogurt, because in the processing of yogurt, lactic acid bacteria have decomposed lactose into lactic acid that can be directly absorbed.
