Lactose intolerance refers to: because there is not enough lactase in the body to completely digest the lactose in milk, lactose will accumulate in the intestines and be used by bacteria, resulting in more lactose intolerant gas, prone to diarrhea, Fart and other symptoms.We should test for lactose intolerance before drinking milk.
About 70% of the world's people have lactose intolerance, except the Nordic lineage. The reason why this genetic feature is mainly because in ancient times, humans used hunting and collecting for a living, and later agricultural life introduced milk-producing livestock. It has only been about 8,000 years since it was steadily drunk.
The cause of lactose intolerance in adults is generally the lack of primary lactose, also known as the lack of adult lactose, which is caused by human dietary habits, and the incidence is related to age and race. Besides, large doses of cephalosporins, lactone amine antibiotics can also cause secondary lactose intolerance.
There is a certain correlation between drinking habits and lactose deficiency.
Due to factors such as heredity, eating habits, etc., some people have low lactase activity or lack of lactose in the small intestine.
The degree of the scene is the life of people. Lactitol deficiency not only causes gastrointestinal discomfort but also affects protein, calcium, iron and other camps.
The absorption of nutrients, increasing the incidence of malnutrition, osteoporosis, and other diseases, can also cause children's growth retardation.
Studies have pointed out that the incidence of lactose deficiency in the Chinese Han population is 75% -95%, and the incidence of lactose deficiency in ethnic minorities is 76%-95.5%.
According to the 2005 survey, the per capita milk consumption in China is only 217 kg, which is only 15 of the world average.
The average amount of milk consumed by people has increased year by year, but it is far from the standard of intake of dietary guidelines for Chinese residents. Chinese have not yet developed the habit of drinking milk for all. Many children will no longer consume any milk and dairy products after weaning. Recently, our hospital study on the improvement of lactose intolerance by exogenous lactose was carried out. The results showed that 61 people usually had milk-drinking habits.
There are 25 lactose-deficient people, accounting for 41%, and 20 of the 29 people who usually have no drinking habits have lactose deficiency, accounted for 69.0%.
The experiment suggests that there is a certain relationship between drinking habits and lactose deficiency, and human milk without the habit of drinking milk.The incidence of glucose deficiency is significantly higher than that of people who have a drinking habit.
Lactose deficiency is a decrease in the activity or amount of lactose in the body so that the ability to break down lactose is reduced. Affected by daily eating habits, the number of people with lactose intolerance is high, so we should pay attention to daily habits.
