Why drink milk to have diarrhea
summary
In our adults, there is such a part of the population who drink pure milk will have diarrhea. What causes us to have diarrhea? How should we deal with this diarrhea? Now let's crack it one by one.
Why drink milk to have diarrhea
One reason: "lactose intolerance" is the main culprit of diarrhea: lactose intolerance is also called "lactose indigestion". Lactose in milk is a kind of disaccharide, because the molecule is too large to be absorbed in the intestinal wall, it needs to be digested into smaller glucose and galactose in the small intestine. However, due to the lack of lactase in the body, adults can not convert lactose in milk into glucose and galactose, which leads to flatulence, abdominal pain, diarrhea and other phenomena. It's called lactose intolerance.
The second reason: "lactose intolerance" is how to produce: after the baby is born, it completely depends on the milk to maintain life and growth, and has the instinct to digest lactose. However, with the age and the gradual growth of the body, especially after stopping drinking milk, physiological changes have taken place, the lactose activity of intestinal mucosa is reduced, and even the lactase in the body will disappear. With the increase of time, the growth of our age, long-term no milk drinking habits, lactase will gradually disappear. If there is no lactase in the body after drinking milk, there will be "lactose intolerance" symptoms.
Reason 3: survey on the proportion of lactose intolerance: the incidence of lactose intolerance is related to race. For example, about 20% of Americans, 80% to 90% of Africans and Asians.
matters needing attention
It is suggested that people with severe lactose intolerance (diarrhea after drinking milk) should not drink milk on an empty stomach. They can eat bread and steamed bread before drinking milk. In this way, lactose and other foods will dilute the concentration of lactose, reduce the stimulation of lactose on the intestinal tract, and gradually the intestinal tract will adapt.
