Lactose Intolerance Test At Home For Baby

You may not know that you have lactose intolerance

Posted on December 23, 2019 by Rebecca

Occasionally I will see someone in the community ask: The gene report said that my lactose metabolism is low, but I have not reacted lactose intolerance. Usually, milk is all right when drinking water. Why?


This is strange. The data show that more than 90% of East Asian populations are genotypes of infant lactose intolerance.

According to the data, if there are so many people who can't drink milk, how can we explain the growing milk market in these years? Many people may not be familiar with lactose and lactose intolerance. Let's briefly introduce the concept of these two nouns.

In nature, lactose is only found in mammalian dairy products (so soy milk does not contain lactose). Whether it is a puppy or a piglet, as long as it is a mammal, it grows up through the absorption of nutrients in the early years, and lactose is an important nutrient in the milk.

What is lactose intolerance? It sounds very powerful. It is meaning, can not stand lactose, drink milk and dairy products will be uncomfortable in the stomach, mainly for abdominal distension, diarrhea baby, and abdominal pain, severe cases may vomit.


The reason is also very simple. There is no lactase in the intestine that can break down lactose. The lactose that has not been decomposed is continuously fermented and fermented by the bacteria in the intestines, causing bloating and venting - that is, farting.

Lactose, which cannot be decomposed in the intestine, also causes an increase in osmotic pressure in the intestine. As a result, water in the large intestine cannot be absorbed, and excessive water is accumulated in the large intestine, resulting in osmotic diarrhea,abdominal pain and bloating , etc. Razor.

Do you think it is very strange to see this, human beings are also mammals, and when they are young, they also want to drink breast milk. Why is there lactose intolerance? Is lactose intolerance sick? Can it be cured?

Humans are indeed mammals and the only animal on earth that will drink milk from other mammals in adulthood. Lactose intolerance is not a disease, but a physiological mechanism for weaning mammals.

Then why do Europeans and Americans have little lactose intolerance, and the proportion of Asians is so high?

First, starting from the study of eating habits, 90% of Asians are not born with lactose intolerance but are affected by the living environment. Asians do not drink milk often and cause later intolerance to milk.

The climate in many parts of Asia is extremely extreme for the livestock industry (such as southern China and South-East Asia in Southeast Asia), too hot and too humid, and naturally, there is no way to widely consume dairy products. For Westerners, dairy products are an important way to consume protein for the body. Cheese is a long-term way to store milk and is more convenient to carry. Asians have developed soy product processing, which is also effective in protein intake.

Today we mainly want to discuss the problem of drinking milk in people with lactose intolerance. Since the East Asian population is almost all genotypes of lactose intolerance, why do people drink in real life, and even some people can drink it every day. Summarizing the discussion, it can be divided into three perspectives:

One: long-term drinking of cattle, your love of living environment has changed the performance of biological performance

Since there are many types of dairy products, people have more choices. Many people have developed the habit of drinking milk since childhood. Nowadays, milk is also very popular. It can be bought at a supermarket or convenience store, although it is lactose intolerant. Gene, but because of the long-term drinking habits of drinking milk, the body has been stimulated to produce lactase to break down, and gradually changed from lactose intolerance to lactose tolerance.

Two: the individual's lactose intolerance is different, each person does not exceed a certain amount of lactose does not have adverse reactions

 Most of the milk on the market today is below 300ml, and in fact, most Chinese people do not drink so much milk every day, and they do not reach the level of lactose intolerance every day, so many people will not have lactose. Tolerance symptoms.

Three: Nothing to drink when you are on an empty stomach

Some people say that because the gastrointestinal motility is faster on an empty stomach, it is not absorbed in the gastrointestinal tract and goes to the large intestine, so it is more likely to cause diarrhea. However, Lily is more convinced that because there is already some content in the intestine when it is not fasting, lactose has less effect on the osmotic pressure of the large intestine, so it is less likely to cause diarrhea. Also, drinking milk on an empty stomach (especially cold) may also cause intestinal irritation in some people with gastrointestinal sensitivities, resulting in diarrhea.
