Lactose Intolerance Test At Home For Baby

Is it poisoned milk or lactose intolerance?

Posted on December 20, 2019 by Rebecca

What kind of food safety situation is most worried about the people? I am afraid I have to count dairy products. On April 22, primary school students from Yuhe Central Primary School in Yulin City, Shanxi Province, experienced collective discomfort after drinking “Student drinking milk”. sixteen students had symptoms such as sudden abdominal pain and diarrhea. A total of 251 students were sent to hospital treatment.

 The China Milk Association explained that "drinking milk on an empty stomach causes lactose intolerance to cause diarrhea" and "does not rule out an emotional transmission." Regardless of whether this statement is the conclusion, what exactly is “lactose intolerance”?

Is lactose intolerance a common phenomenon?

In the media reports related to this matter, some details deserve our attention:

(1) According to the information released by Mengniu Company, diarrhea only occurs in the first group of students who drink pure milk collectively. Althought walnut milk benefits for us.No matter whether they have been drinking juice or milk, they are not able to drink walnut milk or yogurt.

(2) According to Pang Guohuai and Mengniu, the headmaster of Yuhe Town Center, there are many poor students in the school. Students generally do not have the habit of eating breakfast. The milk is drink on an empty stomach in the morning without heating.

(3)According to the report of China Dairy Association and China Academy of Inspection and Quarantine, no pathogens were detected in related products and student stool samples. Only 16 students had adverse reactions and their physical condition was restored on the same day.

From these details, lactose intolerance seems to make sense.We should test for lactose intolerance.

The so-called lactose intolerance is that the human body cannot tolerate lactose. The milk that people drink contains about 4.5% of lactose, and as a macromolecular disaccharide, it needs to be broken down into two kinds of monosaccharides, glucose, and galactose, in the small intestine to be absorbed by the intestinal wall.

The body needs the help of lactose to break down lactose, but many people cannot effectively decompose lactose in milk or other foods due to lack of lactose in the intestine. Lactose that has not been decomposed may be fermented by bacteria at the end of the ileum and the colon, thereby producing gas, causing bloating and venting.

Many people think that lactose intolerance has nothing to do with themselves. The opposite is true  lactase deficiency  accounts for the majority of adults worldwide. But the difference is also very large, only 5%-30% of European white people in different regions will have lactose intolerance, while more than 90% of Asian yellows have lactose deficiency. In China, the rate of lactose malabsorption in healthy adults is as high as 92%! Was it shocked by this number?

Lactose deficiency can be clinically divided into three types. The first type is congenital and rare. Followed by hairstyle, the last and most common one is the lack of primary lactose. In many remote areas that are not often exposed to dairy products, or families who are not used to drinking milk, once the child is weaned, they will no longer feed the milk. Because of the lack of exposure to lactose, the lactose in the intestines is “ laid off”. The ability to digest lactose is also decreasing year by year. Once the child suddenly drinks a lot of milk, it is prone to lactose intolerance.

According to a survey conducted by the Institute of Nutrition and Food Hygiene of the Chinese Center for Disease Control and Prevention on 1168 children aged 3-13 in four major cities, the northern cities (Beijing, Harbin) are 3-5 years old, 7-8 years old, 11-13 years old. The incidence of lactose intolerance in children of three age groups was 13.95%, 45.5%, and 43.8%, respectively, and that in southern cities (Shanghai and Guangzhou) was 10.5%, 21.2%, and 17.4%.

According to reports, the incident occurred in Yulin City, the northernmost part of Shanxi Province. It was the first time that poorer primary school students drank pure milk and honey (the milk content of milk drinks before drinking was lower), and cold milk + fasting made milk in the stomach. The residence time is short, and a large amount of lactose is quickly collected in the small intestine, stimulating the intestinal wall, which may naturally cause diarrhea. Considering that the event is targeted at young children, the possibility of suggesting a group snoring also exists.

So, are the children's symptoms considered food poisoning? Food poisoning should be consistent with a range of epidemiological characteristics that can trigger a range of acute gastroenteritis symptoms. such as. Most food poisoning is bacterial and should be able to detect the corresponding pathogens in food, vomit, and feces. According to the authoritative department, no pathogens were detected in the relevant products and the stool samples of the students.

In daily life, it is easy to confuse food allergies with food intolerance. The same is not suitable for milk, some people may be lactose intolerant, and some people may be allergic to milk protein, which is different in a mechanism. Food allergy refers to an abnormal immune response caused by food, and food intolerance does not trigger our immune response.

There are three main symptoms of milk protein allergy

The first one is the gastrointestinal symptoms. Children may have unexplained vomiting, bloating, constipation, and even blood in the stool.

The second type is skin symptoms. Children may develop acute urticaria, or It is chronic eczema;

The third is respiratory symptoms, children often have unexplained coughing, sneezing and other cold-like symptoms, and severe asthma.

For the detection of lactose intolerance, you can go to the hospital for related tests on lactose intolerance. There is galactose determination. The technique is mainly to measure the lactose tolerance of the human body and guide the public to drink milk. This new technology is testing. When human lactose intolerance is more accurate, and it is supported by everyone, many patients use this diagnostic method to diagnose.

Many diseases are based on clinical symptoms to determine what disease. The symptoms of the human body, such as sugar intolerance, are mainly diarrhea and uncomfortable stomach. Some children may be greatly affected during normal times, and habitual gastroenteritis may occur.


Milk is the best source of dietary calcium and has the nutritional value that is difficult to replace with other common foods. According to a recent national nutrition survey, the average daily milk intake per person in the country is the only 26.4g, and the average city residents do not reach 100g per day, not to mention the recommended value of 300g milk per day in the Chinese Dietary Guidelines. The current general problem is that milk is too little, which is why the country began to promote the “student milk” program since 2000.

Even if you lack lactose, there is nothing to be afraid of under scientific guidance. Determine the cause, choose the correct intolerance product for dietary adjustment, and self-heal after some time.
