1. What is lactose intolerance

Lactose intolerance, also known as lactose indigestion or lactose malabsorption, refers to a state in which no lactase that breaks down lactose is produced in the human body. It is a congenital hereditary expression that occurs frequently in Asia.

Lactose is a kind of sugar in mammalian dairy products (human milk, milk, goat milk, etc.), which is a disaccharide. It needs to be decomposed into glucose and galactose by the action of lactase to be absorbed by the body. Since the intestines of the patient cannot secrete enzymes that break down lactose, the lactose is digested and absorbed and is used by the human body. Lactose is broken down by bacteria into lactic acid in the intestine, thereby destroying the alkaline environment of the intestine, and causing the intestinal tract to secrete a large amount of alkaline digestive juice to neutralize lactic acid. Therefore, mild diarrhea is easy to occur.

The main symptom is the symptoms of diarrhea and bloating after ingesting a large amount of lactose. Whether the symptom is genetically determined or not is contagious. Some people's symptoms will decrease or worsen over time. Besides, there are still more people with lactase deficiency, but without the above performance, lactose metabolism in the body is still abnormal, called lactose malabsorption.

Fresh milk is the main food for young children before weaning. Lactose intolerance during this period should promptly consult a doctor to avoid malnutrition. Lactose intolerance that occurs after weaning is common among people other than white races.

People with lactose intolerance do not develop symptoms such as diarrhea in babies immediately after taking a small amount of lactose, but only when the intake exceeds a certain amount. Therefore, most people with lactose intolerance can still drink milk, but not excessive. For example, although more than 90% of Japanese people have lactose intolerance, most people can drink 200 ml of milk a day without any discomfort.

If ordinary people do not drink milk regularly, there will be diarrhea, which is also a manifestation of lactose intolerance. Lactase will disappear in the human body if it is not used for a long time. With long-term drinking milk, lactase will regenerate, so diarrhea begins. People should insist on drinking milk for a while, and then there will be no diarrhea.

However, yogurt is fermented to ferment the lactose in milk into lactic acid, so it does not cause symptoms of human diarrhea. The value of milk and yogurt is the same.

There is no consistent conclusion on the timing and location of this mutation. Some people think that it was independent in Sweden and the Arabian Peninsula in the first 4,000 years and gradually merged in the expansion. Some people think that it was extended to other places after the emergence of the Middle East in the last 4,500 years. Others believe that the mutation appeared independently in the Tutsi of East Africa at a later date. The current situation is that most of the ancestors of Western Europe have the mutation in their genes (meaning they can digest lactose for life), while East Asians, sub-Saharan Africans, and Native American and Oceanic aborigines do not. It means that they will develop lactose intolerance in adulthood). On average, 75% of the world's people develop symptoms in adulthood, so it is better to call it a disease than to call it a natural condition.

In the absence of lactase, lactose ingested by humans cannot be digested and absorbed into the blood but is retained in the intestines. A large amount of gas is generated during the process of intestinal bacterial fermentation to break down lactose. Causes bloating and farting. Excess lactose also increases the osmotic pressure inside the intestine, preventing the absorption of water and causing diarrhea.

Mammalian larvae begin to gradually reduce lactase synthesis after weaning. Human children usually lose 90% of their lactose digestive capacity when they are 4 years old, but the difference between them is g2reat. In some races, mutations occur on chromosome 2, which can stop the reduction of lactase, so these people can digest lactose for life.

2. Classification of lactose intolerance

The lactose that the human body eats when it enters the colon, can be fermented by bacteria to form short-chain organic acids (such as acetic acid, propionic acid, and butyric acid), as well as gases such as methane and carbon dioxide. In the human body, the process of lactose fermentation can also cause a series of symptoms such as abdominal pain, bowel, diarrhea, which is medically known as lactose intolerance.

In medicine, lactase deficiency can be divided into the following three types:

1. Congenital lactase deficiency. This is due to the recessive genes on the chromosomes of some people. In general, this type is relatively rare in the clinic.

2. Secondary lactase deficiency. This condition refers to the damage of the intestinal mucosal epithelium caused by some reasons, resulting in a temporary decrease in lactase activity. There are many reasons for this, including infectious diarrhea, celiac disease, Crohn's disease, malnutrition, and immunoglobulin deficiency.

3, primary lactase deficiency (also known as adult lactase deficiency), which is caused by the gradual decline of lactase activity as people age, and is the most common type in clinical. Its timing varies from person to person, and some people begin to appear after the baby is weaned. In China, it is more common in people aged 7-8.

3. Lactose intolerance affects the human body

Lactose intolerance means that some people lack lactose due to the intestinal tract and cannot digest the lactose in the milk. This causes gastrointestinal symptoms such as bloating, abdominal pain and nausea after eating milk and dairy products.

Among the populations with lactose intolerance, the black and yellow populations are the most frequently seen because the two populations rarely touch dairy foods during infancy.

In China, more than 10% of infants and young children in lactation will have congenital lactase deficiency symptoms, and this proportion will become higher and higher with age.

The study shows that the incidence rate of children aged 3-5 years is 38.5%, the incidence rate of children aged 7-8 years is 87.6%, and the incidence rate of children aged 11-13 years is 87.8%, while the rate of lactose malabsorption in healthy adults is as high as 92%.

The main manifestations of lactose intolerance are some gastrointestinal symptoms, such as abdominal tension, bowel, abdominal pain, exhaust, and diarrhea. If these symptoms are one of the manifestations of lactose intolerance, the symptoms of individuals with lactose intolerance vary widely, while severe lactose intolerance occurs more than 30 minutes to several hours after ingesting a certain amount of lactose.

Lactose intolerance has a great impact on infants and young children and is accompanied by diaper rash, vomiting, growth retardation, etc. Adults sometimes have nausea reactions. The number and severity of intolerance symptoms are related to a variety of factors, such as lactase activity in the small intestine, the amount of lactose ingested, and whether other foods are ingested at the same time.

Lactose intolerance affects various minerals in milk, such as calcium, iron, phosphorus absorption, resulting in calcium deficiency, zinc deficiency and iron deficiency and pelvic blood symptoms; lactose intolerance can also cause vitamins, protein and other infants in milk The essential materials for growth and development of young children are difficult to be digested and absorbed by children, causing problems such as low body weight and slow growth and development.

Because lactose is intolerant, when drinking milk, milk can not be completely decomposed, digested and absorbed in infants and young children, and stays in the intestinal cavity. Under the action of bacteria, various harmful substances are formed, causing intestinal flora imbalance and causing gastrointestinal problems. Long-term lactose intolerance can lead to diarrhea in children with chronic diarrhea and diarrhea that are difficult to cure in children.

If your baby is lactose intolerant, you may experience diarrhea, abdominal cramps, bloating or farting between 30 minutes and two hours after drinking breastfeeding diet or eating other dairy products (such as cheese or yogurt that you start after eating complementary foods). It should be noted that the baby should not drink fresh milk until the age of one.

Lactose intolerance occurs less frequently in infants and is more common in adults. According to reports, the proportion of Chinese with lactose intolerance is as high as 93%. Most people have symptoms of intolerance only when a certain amount of lactose is ingested, and only a very small number of people take a small amount of lactose to have a serious condition. Infants usually synthesize lactose normally, so they can digest and absorb lactose in breast milk. After weaning, the synthesis of lactose in the body will gradually decrease. Lack of lactose intolerance can result in lactose intolerance in the small intestine due to various reasons.

Although lactose intolerance has a great impact on the human body, there are many effective ways to deal with it, and the right product should be chosen.

4.Measures and methods for reducing or eliminating lactose intolerance

The lack of lactase can pose a hazard to the population of all ages and is related to the nutritional and health problems of the world's population. How to solve this problem has been increasingly valued by many scholars at home and abroad. Currently, a variety of measures have been taken to improve lactose intolerance.

Improve eating habits

lactase
lactase

Studies have shown that the strength of lactose intolerance is related to the amount of lactose intake, gastric emptying time, intestinal transit time and colonic flora. Studies have shown that the daily intake of a certain amount of lactose can reduce bloating, diarrhea, and can make lactose malabsorbers tolerate large doses of regular lactose.

He believes that there are three reasons for this. One is that the sensitivity of different individuals to lactose intolerance is different. Second, the high-dose lactose in the test is divided into three small doses and taken together with other foods. The absorption of lactose has a great influence; thirdly, the yield of hydrogen in the test group is significantly lower than that of the control group, indicating that the lactose adaptability of the colonic flora can be gradually enhanced. People with lactose intolerance are more resistant to lactose ingestion with other foods than lactose, which is usually able to tolerate 6 g of lactose.

Therefore, people with lactose intolerance can take a certain amount of lactose daily, gradually increase the amount of lactose intake and consume other foods (especially meat or solid foods) while eating high lactose foods. It is also possible to replace dairy products with high lactose content with yogurt and fermented cheese. By improving these eating habits, the symptoms of lactose intolerance will gradually diminish.

Production of low lactose dairy products

diary

To eliminate the effects of lactose on patients with lactose intolerance and increase the intake of dairy products, researchers at home and abroad have done a lot of work on lactose in cow's milk for many years, including treating milk, removing or destroying it. lactose. Mainly include ultrafiltration concentrated milk, enzymatic hydrolysis of lactose milk, fermented milk, production of low lactose milk by bioreactor.

Ultrafiltration concentrated milk

Ultrafiltration is a new separation technology that emerged in the 1970s. It is easy to operate and low in cost. It is filtered from milk, lactose and other small molecules that can be concentrated through a semi-permeable ultrafiltration membrane with a molecular weight of about 10,000. And the protein is concentrated. Concentrated milk preserves other nutrients in the milk and has little lactose. It is suitable for adults who are lactose intolerant, but not suitable for infants who are breast-based. This method also removes a variety of minerals and vitamins.

Fermented milk

This method is an effective measure to solve the problem of social lactase deficiency. Yogurt is produced by fermenting lactic acid bacteria. The bacterium contained in the yogurt has β-galactoside sugar, which can decompose lactose and facilitate the absorption of the body. However, yogurt cannot solve the body's lactase deficiency from the roots and can only be used as a substitute for dairy products such as milk. Yogurt is not like everyone, and it is not easy for infants to feed.

Nowadays, the problem of absorption and utilization of lactose is gradually attracting people's attention. Consumers reduce and avoid lactose intolerance through changes in their eating habits. Dairy manufacturers are exploring new products and introducing new technologies to reduce lactose content in dairy products while maximizing the protection of other nutrients... There are many types and methods for producing low-lactose products in the dairy industry today, including ultrafiltration concentrated milk, fermented milk, enzymatic decomposition of lactose milk, and the use of bioreactors to produce low lactose milk.

In Aisa, a high incidence area of ​​lactose intolerance, the incidence of lactase deficiency in children is also high. Therefore, research on the solution to lactose intolerance is of great practical significance for solving the health problems of Asia people.

5. Lactose intolerance vs milk allergy

Lactose intolerance stemming from the digestive system

Lactose is a disaccharide that is widely found in mammalian milk. About 4.5 grams of lactose is contained per 100 milliliters of milk. Lactose can be absorbed after it is broken down into glucose and galactose by lactase in the human small intestine. Infants usually synthesize lactase normally, so they can digest and absorb lactose in breast milk. After weaning, the synthesis of lactase in the body will gradually decrease. If the lactase is lacking in the small intestine due to various reasons, a large amount of undigested lactose can reach the large intestine smoothly. Some bacteria in the large intestine use lactose to ferment, which produces a lot of gas, which can cause bloating, diarrhea, and fart. This is lactose intolerance.

lactose intolerance-milk allergy
lactose intolerance-milk allergy

Milk allergy from the immune system

Milk allergies, or rather, allergies to proteins in milk. It contains about 3 grams of protein per 100 milliliters of milk, including casein and whey protein. Both proteins can cause allergies. When the immune system mistakes the normally ingested milk protein as an invading enemy, it triggers a series of immune responses against the "enemy." As a result, it may cause symptoms such as vomiting, diarrhea, redness of the skin, and asthma. When the immune response is too strong, the rescue is not timely and may even lead to death.

Because the baby's immune system is not yet mature, infants are more susceptible to milk protein than adults. About 3% of babies are allergic to milk protein. Moreover, babies who are allergic to milk proteins are often allergic to proteins from other animal milk and even to proteins in breast milk. Besides, in addition to milk protein, proteins in eggs and peanuts are often allergens in infants. In most cases, this allergy problem will disappear on its own after a few years. Of course, there are also a few people who are allergic to certain proteins even after adulthood, such as Howard, who is severely allergic to peanuts in TBBT.

6. The role of lactase

Milk and dairy products are natural foods with rich nutrients. The nutritional value has long been recognized by the world. However, the fly in the ointment is the lactose intolerance caused by the lack of lactase in some people, which affects their normal intake of dairy products. In, this has largely restricted the popularity of dairy products in people's daily lives and the digestion and absorption of nutrients in dairy products. With the development of modern biological science and technology, people use lactase to direct the hydrolysis of a large amount of lactose in milk, which makes it possible to solve the problem of lactose intolerance, which has been a difficult problem for many years.

(1) Biological functions of lactase

Lactase can decompose lactose in the human body into glucose and galactose. Glucose is a source of energy for metabolism in various parts of the body, and galactose is an increase in resistance. These techniques have been applied to the production of human proteins in the pharmaceutical industry. The use of transgenic technology in the cow's body to improve the internal anti-bacterial mechanism to protect against cow mastitis or to produce new anti-bacterial proteins or peptides through the mammary gland can also increase its resistance.

(2) The significance of pretreatment of milk with lactase

About 30% of calories in whole milk and 60% of skim milk are provided by lactose. For people with lactose intolerance, this energy cannot be fully utilized once the body's energy needs are not met (nutrition Children), protein is only used to meet energy needs, not as a unit of human protein. Lactose is different from other sugar substances. It is a carrier of mineral components and promotes the absorption of mineral elements.

Therefore, if lactose is not absorbed, it will be discharged into the intestine and fermented by intestinal microbes to produce acid and produce gas, which leads to gastrointestinal dysfunction and loss of valuable protein and minerals such as iron, zinc, and calcium. Loss of quality, which is related to rickets in children and osteoporosis in adults.

Experts' research results show that patients with lactase deficiency have poorer bone structure than normal people, and more seriously if lactase is absent in the body, lactose will not be hydrolyzed into monosaccharides (glucose and a half). Lactose is used for absorption and utilization by the human body, and galactose can promote the synthesis of cerebroside and mucopolysaccharide, thereby promoting the mental development of young children.

Lactose absorption disorder is not only accompanied by signs of lactose intolerance, but also accompanied by decreased appetite, resulting in reduced diet, diarrhea, and loss of a certain amount of food that has been digested. These digested foods can be absorbed but not absorbed. (including valuable protein, microbes, minerals and some sugar in milk), making the use of milk very low, also wasting the precious dietary resources of milk.

(3) The significance of lactase on the hydrolysis of milk in milk:

①can provide high-quality protein and special sugar source for children with malnutrition and frail patients;

②The lactose intolerant and the cattle intolerant camps relieve the pain of not drinking milk;

③can generally improve people's digestion, absorption and utilization of various protein, vitamins, minerals and sugars in dairy products, promote the growth of beneficial bacteria in the intestinal tract, and promote the majority of the population

A variety of nutrients in the product are more comprehensive and more direct absorption, which is good for your health.

Xiao Li saw a question and answer questions on the Internet a few days ago. The title is "What is the thing that the British driver from the heir to the taxi driver had eaten when he was a child?" At that time, Xiao Li thought it would be a popular British snack, but The result turned out to be lactase. After seeing the answer, Xiao Li was somewhat skeptical. In Europe, which has the lowest probability of lactose indigestion, how could there be a country where all people eat lactase? So curious, Xiao Li checked the efficacy of lactase, but did not expect to have a lot of benefits to eat lactase, Xiao Li this letter, then let us see what are the benefits?

prevention of lactose indigestion

We all know that the biggest effect of lactase is that it can help the body to break down and absorb lactose, and avoid breastfeeding diarrhea after breastfeeding. In China, 80.6% of babies will have a lack of natural lactase and cannot decompose and digest lactose. Therefore, parents should take lactase for others after birth, to prevent lactose indigestion.

shorten diarrhea time

Infancy is the time when lactase is most abundant in our body, because as the body grows, the activity of lactase will gradually weaken and become less and less, but the amount of lactase in the body is closely related to diarrhea, and if In the case of diarrhea, timely lactase supplementation can also alleviate the symptoms of our diarrhea and shorten the time of our diarrhea. Therefore, parents should deliberately add lactase to their baby from an early age to ensure their intestinal activity and prevent frequent diarrhea in their baby...

to avoid affecting the development

Lactose is an indispensable source of energy in the baby's body. It plays a vital role in growth and development. The reason why the baby can absorb lactose is that the lactase in the body helps them to decompose and digest lactose before they can be absorbed smoothly. Therefore, for the healthy growth of the baby, it is really necessary to start lactase from the beginning of their birth.

treatment of gastrointestinal dysfunction

Baby is not perfect due to organ development, the body is relatively fragile, so it is often easy to get sick, especially the baby's gastrointestinal function, it is more vulnerable, but if you do not pay attention, the baby is likely to have diarrhea, in fact, this It is irrelevant to the digestive and absorbing function of the baby's small intestine. However, to alleviate this situation, in addition to taking medicine, parents need to take lactase for the baby, which can play a role in adjuvant therapy.

Therefore, lactase has a certain effect on lactose intolerance. Lactase can prevent lactose intolerance. Lactase is appropriately supplemented to hydrolyze lactose to glucose and galactose. Thereby avoiding the symptoms of lactose intolerance. Lactose is an indispensable source of energy in children. It is a kind of carbohydrate that plays a vital role in children's growth and development.

7.Factors associated with lactose deficiency

     The most serious threat to the human body caused by lactose deficiency is the impact on nutritional status, especially for young children and the elderly. The investigation found that lactose deficiency, the height and weight of young children are significantly lower than normal children, and the prevalence of rickets and anemia is significantly higher than normal children. In addition, lactase deficiency can not or less take calcium from milk, lower bone density, and increase the prevalence of osteoporosis. Therefore, in order to understand the cause of lactase deficiency, it is of great significance to pay attention to its correct diagnosis. The relevant research is summarized as follows.

(1)Lactose deficiency and classification

Lactose, also known as B-galactosidase, is present on the surface of the small intestinal mucosa. It is encoded by the lactose gene of about 50b on the long arm of chromosome 2 and has two enzyme activities: lactose and phloridzin. The expression of lactose is restricted by the intestinal epithelial cells or absorptive cells to the distal end of the duodenum and the jejunum, and the duodenum proximal and ileum has the lowest activity.

(2)Factors associated with lactose deficiency

Racial factors

It is reported that the incidence of lactase deficiency is highest in African American and Asian ethnic groups, close to 10%; blacks and Nordic Jews are 60%-80%; Mexico, Spain and South Africa are 50%-80%, while whites People are only 2%-15%. The incidence of LD in Han Chinese adults is 75%-95%, and 76.4%-95.5% in ethnic minorities.

Genetic factors

Studies have found that adult lactase deficiency is associated with single nucleotide polymorphisms C/T13910 and C/A22018 located at the 14M and 22b positions upstream of the lactose gene, respectively. Among them, LCr13910c/ is closely related to lactase deficiency. The study also found that genotype C/C13910 was negatively correlated with lactase activity and genotypes CT3910 and Tr13910 were positively correlated with lactose activity.

Trench factors

The closer the geographical location in Europe to the south and east, the higher the incidence of lactose deficiency from 2% in Scandinavia to 70% in Sicily. India also has an increase in the incidence from north to south. However, the incidence of lactase deficiency in residents in the same area is higher than that of herders. Whether this difference is related to the eating habits of herders remains to be studied.

Age factors

Relevant data show that lactose activity continues to decline with age, with 90%-95% of people losing their original lactose activity in early childhood. The activity of lactose in the body is increased from the late gestation period to the mid-neonatal level and begins to decline at the age of 2-15 years. So far, the body begins to express lactose into lactose intolerance. However, 45% of lactose-intolerant women will be able to recover lactose deficiency in children aged 0-6 years in Shanghai during the pregnancy to the ability to recapture lactose and found that the incidence of lactase deficiency was 74%, as the age increases and rises.

A survey of children in four cities in Beijing, Shanghai, Guangzhou and Harbin showed that the incidence of lactase deficiency in children aged 3-5 years and 7-8 was 38.5% and 82.6%. The specific age at which the activity begins to decline depends to a large extent on the ethnic, cultural background, especially the development of the dairy industry. The decline in lactase activity in China begins with 3-5 years old. But some scholars believe that it started at 7-8 years old.

With the increasing consumption of milk and dairy products, the high incidence of lactose deficiency in the population has gradually increased the problems associated with lactose absorption. The research on lactose deficiency has also received increasing attention, and new diagnostics and treatments are constantly being made. The method came out. With the deepening of the research on the level of lactose gene, the method of genetic testing is gradually improved, and the method of improving lactose deficiency is also expected to increase. At present, no matter which kind of detection or treatment method has its drawbacks, it is believed that with the joint efforts of many scholars, there will be new breakthroughs in the detection and treatment of lactose.

8. The effect of lactase deficiency on milk absorption

milk
milk

Milk contains lactose. After lactose enters the human body, it needs the participation of lactase to be digested and absorbed into nutrients that we can use. A molecule of lactose can be broken down into a molecule of glucose and a molecule of galactose by the action of lactase. Lactase is present in our small intestine. If lactase is deficient, or lactase activity is low, we can't digest lactose very well in the small intestine, and lactose will pass through the small intestine and reach the large intestine. There are many bacteria in the human large intestine. The bacteria break down lactose to produce a lot of gas and organic acids, which causes symptoms such as abdominal bloating and diarrhea. This is the process by which lactose intolerance occurs.

When we were young, we were able to drink milk and digest lactose. However, as we grew older, our body no longer produced lactase or decreased lactase activity. Drinking milk would be uncomfortable. Adults who still maintain lactase activity in the gut are partly due to genetic mutations in their ancestors. By analyzing 1611 DNA samples from 37 populations, the scientists found that the -13910T/-22018A chromosomal haplotype was associated with lactose tolerance, suggesting that lactose tolerance may be derived from different mutations in Europe and Africa. These data demonstrate that mutations in the LCT (lactose intolerance) gene are a distinct adaptive evolution and are the result of a common cultural feature - the strong selection pressure caused by animal domestication and adult milk consumption.

Lactose deficiency

Milk is rich in nutrients and is a good source of protein and a source of calcium. The Chinese Nutrition Society recommends that adults should consume 300 grams of dairy or liquid milk a day, and the results of Chinese residents' nutrition and health monitoring from 2010 to 2012 show: Chinese urban and rural residents The average daily milk consumption is only 24.7 grams, which has not reached one-tenth of the recommended amount of 300 grams.

Chinese people are so cautious about dairy products, and they can't get rid of the high incidence of lactose intolerance. If you deliberately drink less milk because of lactose intolerance, resulting in a low intake of dairy products, long-term accumulation may affect the body's nutritional status.

Some people give up drinking milk because of lactose intolerance, which is a very unwise act. First of all, milk is indeed a very good food, even set to "white blood". In fact, the nutritional value and nutrient ratio of milk are quite reasonable. You only need to drink milk to grow. Various nutrition.

Milk is rich in minerals and milk is the best source of the human body. If long-term absorption of protein and calcium is insufficient, it is loose for children and short for children: for adults, it is osteoporosis and easy to fracture.

The 2016 China Food Guide recommends that 300 grams of liquid milk per day. This 300 grams of milk can provide us with 300mg of calcium, 9 grams of high-quality protein, which can achieve 37.5% of calcium intake, 30% of high-quality protein, which means that a cup of milk basically meets 1/3 of calcium per day. Protein requirements. If you don't drink milk, you can get these proteins by eating meat, but avoid excessive fat.

9. Infants and young children lack the harm of lactase

Lactose intolerance, also known as lactose indigestion or lactose malabsorption, refers to lactose deficiency in the human body, which causes the lactose in milk to be converted into galactose and glucose which are easily absorbed by the adult body, thus affecting the digestion and absorption of lactose.

Lactose deficiency, the lactose ingested by humans can not be digested into the blood, but left in the intestines. A large amount of gas is generated during the process of intestinal bacterial fermentation to break down lactose. Causes bloating, venting, and bowel. Excess lactose also increases the osmotic pressure inside the intestine, preventing the absorption of water and causing diarrhea and colic.

The harm of lactase deficiency:

Infants with early lactose intolerance will have problems such as spitting milk, diarrhea, constipation, bowel, bloating, abdominal pain, venting, etc. Easy to cry. When the baby is 4 to 6 months old, there will be occasional three or two days. The amount of milk consumed is reduced, and it has a bad appetite. I don't want to eat. This is the baby's unique anti-milk phenomenon. He Mingjiao said that the period of babies may appear in the baby 3-4 months, and may also appear in about 6-10 months. There are many reasons for causing the baby to be tired of milk, but it can be divided into physiological anorexia and pathological anorexia.

Physiological anorexia has a short duration, most of which is two or three days. At this time, the baby's mental state is normal, and there will be no abnormalities such as fever, crying, etc. Parents do not have to worry.

Pathological anorexia is caused by the disease that the baby is unwilling to eat milk, some lactose intolerance and vomiting, diarrhea caused by the phenomenon of malnutrition. The other is an acute infection. For example, thrush can cause oral pain. When children drink milk, they will feel pain and refuse to eat. Therefore, in addition to tired of breasts, there will be other abnormal performances, such as poor sleep, lack of energy, easy to cry, and even bloating, vomiting, fever or shortness of breath. Parents should pay attention to it and go to the hospital for medical treatment. The phenomenon, lactose intolerance can not be treated in time will cause infants and young children to be tired of milk, affecting their growth and development.

The consequences of calcium deficiency in newborns are relatively large, especially severe calcium deficiency, which can easily lead to neonatal rickets, new teeth, late teeth, irregular teeth, and anorexia eclipse, etc. Conducive to the growth of children.

Milk contains trace elements essential for the growth and development of human bones, muscles, organs, brains, etc. Because lactose intolerance can not absorb the nutrients in milk, infants and young children with malnutrition generally have various symptoms of malnutrition.

The galactose formed by milk under the action of lactase is an essential substance for the development of the baby's brain, and the long-term lactose intolerance affects the brain development of infants and young children.

At the same time, dry lactose is intolerant. After drinking milk, milk can not be completely decomposed, digested and absorbed in the intestines of infants and young children, and various harmful substances are formed under the action of bacteria. It causes intestinal flora imbalance. Causes gastrointestinal problems, long-term lactose intolerance can lead to chronic diarrhea that is difficult to cure in children; some children will induce diaper rash.

Osteoporosis
Osteoporosis

Lactose intolerance affects various minerals in milk. Such as the absorption of calcium, iron and phosphorus. Causes the baby to be deficient in calcium, zinc deficiency, iron deficiency and anemia.

   Lactose intolerance can also cause the growth and development of vitamins, proteins and other infants in milk, which are difficult to be digested and absorbed by children. It is suitable for children with low body weight and growth retardation. In severe cases, the complications induced by lactose intolerance may endanger the life of the child.

10. Lactose intolerance and infant health

Lactose intolerance refers to the lack of lactase in the intestines of the human body, which does not digest the lactose in the milk, resulting in bloating, abdominal pain, nausea and other gastrointestinal symptoms after consumption of milk and dairy products.

Lactose intolerance is very common in the black and yellow population. Lactose intolerance can occur in infancy due to congenital or acquired conditions.

Lactose is the main sugar in milk. The lactose content in human milk, milk and goat milk is different, and human milk contains 7% lactose. Milk contains 4.2% lactose, goat milk contains 4.6% lactose, and lactose content in cattle and goat milk is lower than human milk. Lactose has no sugar cane sweetness, and its sweetness is one-sixth of that of cane sugar.

(1) The effect of lactose intolerance on nutrition

Lactose not only provides energy to our body, but also its own decomposed galactose is the most important nutrient for brain cells and nerve cells. Long-term lack of galactose can cause mental retardation and stunting in infants and young children. And the key to infant brain development before the age of one year, even after this critical period, even adding more lactase to infants and young children does not help, because this process is "irreversible", so this will greatly hurt the baby. Young children.

(2) Structure and metabolism of lactose

Lactose is a kind of disaccharide, the molecular formula is C12H22O11, which is a disaccharide in mammalian milk, hence the name. Its molecular structure is formed by the condensation of a molecule of glucose and molecular galactose.

The main function of lactose is to supply heat to the body. Lactose is the most abundant sugar in milk, and the sugar contained in milk.

9.8% is lactose, growth and development of children and adults, metabolism, tissue synthesis, maintenance of normal body temperature and physical exercise

Labor work requires a lot of heat, especially in children, the decomposition, digestion, absorption and utilization of sugar are more vigorous than adults. Lactose is the driving force for the development and activity of organs, nerves, limbs and muscles in children.

   Metabolism of glucose and galactose. Glucose is absorbed into the blood and metabolized to produce energy. Galactose is absorbed into the blood and enters the liver and is converted into hepatic glycogen into the blood when needed.

Children's brain cells and the entire nervous system all require a large amount of lactose. Children under one year of age need about 13 grams of sugar per kilogram of body weight per day.

At the same time, lactose can maintain the balance of water in the body, provide galactose related to the composition of the brain and vital organs, and is also necessary for the storage of starch. Galactose is particularly important for children's brain development, which promotes the production of glycosides and mucopolysaccharides. Lack of lactose can cause children to lose weight, reduce body weight, slow growth, and even children who consume protein in the body may develop protein deficiency.

Galactose can constitute cerebroside, which is a component of cerebrosides in the cranial nervous system and is closely related to the rapid growth of the brain after birth.

Lactose can promote intestinal probiotics and inhibit intestinal pathogenic bacteria. Another important role of lactose is to promote the intestinal tract of children

The lactic acid bacteria in the intestines grow and grow. In the intestine, lactose produces lactic acid under the action of lactic acid bacteria, various enzymes and certain microorganisms. The lactic acid has a protective effect on the gastrointestinal tract of children, which can inhibit the toxin produced by abnormal fermentation in the intestine. The poisoning caused by it can also inhibit the reproduction of harmful bacteria in the intestines.

Lactic acid promotes probiotics and inhibits the growth and reproduction of pathogenic bacteria. There are 100 trillion bacteria in the human body, 500-1000 kinds, and the fineness in the intestine is about 1-15 kg. Most probiotics are necessary to maintain the body's immunity and physiological functions.

(3) The role of probiotics

1.promote digestion

Probiotics can ferment lactose to produce lactic acid that is easier for the body to digest and absorb. Hydrolyzed indigestible proteins. Increase the content of soluble calcium, phosphorus and B vitamins in the intestine. Probiotics can also promote the secretion of digestive enzymes, further promoting digestion and absorption. Promote bowel movements and prevent constipation.

Lactose intolerance, after drinking milk, milk in the infant can not be completely decomposed, digested, absorbed and retained in the intestinal lumen, under the action of bacteria to form a variety of harmful substances. It causes intestinal flora imbalance. Causes gastrointestinal problems, chronic lactose intolerance causes chronic diarrhea that is difficult to treat in children, and some children may induce diaper rash.

2. activation of intestinal mucosa related rabbit disease system

Probiotics can activate intestinal submucosal lymphoid tissue and promote the secretion of slgA by B cells. It stimulates macrophage and T lymphocytes to secrete cytokines. The systemic immune system is activated by lymphocyte recirculation, thereby improving the body's immune function.

(4) Decomposition of lactose into lactic acid to promote calcium absorption

Another role of lactose is to promote calcium absorption in children during the metabolism of calcium. Lactose decomposes to produce lactic acid, which promotes calcium absorption

The use of calcium lactate, calcium lactate has the characteristics of high solubility, fast dissolution rate and high bioavailability. It can prevent and treat calcium deficiency, such as rickets, refractory diarrhea and other diseases can affect the absorption of vitamin D, calcium and phosphorus and suffer from rickets.

(5) Therapeutic significance of lactose intolerance

  The intestine is not only the largest digestive and absorbing organ in the body, but also the largest immune system in the body. The submucosal lymphoid tissue is widely distributed under the intestinal mucosa, which constitutes the first barrier to prevent the invasion of pathogens. The function of the intestinal barrier function is closely related to the health status and disease resistance of the human body.

  In general, lactose is a very important nutrient in the early nutrition of infants and young children and has an irreplaceable effect on the growth and development of infants and young children. Lactose intolerance can affect the growth and development of infants and young children and even affect mental development. Lactase supplementation is an effective measure to address lactose intolerance and can better promote breastfeeding diet.

9. Infants and young children lack the harm of lactase

Lactose intolerance, also known as lactose indigestion or lactose malabsorption, refers to lactose deficiency in the human body, which causes the lactose in milk to be converted into galactose and glucose which are easily absorbed by the adult body, thus affecting the digestion and absorption of lactose.

If having lactose deficiency, the lactose ingested by humans can not be digested into the blood but left in the intestines. A large amount of gas is generated during the process of intestinal bacterial fermentation to break down lactose. Causes bloating, venting, and bowel. Excess lactose also increases the osmotic pressure inside the intestine, preventing the absorption of water and causing diarrhea and colic.

The harm of lactase deficiency:

Infants with early lactose intolerance will have problems such as spitting milk, diarrhea, constipation, bowel, bloating, abdominal pain, venting, etc. Easy to cry. When the baby is 4 to 6 months old, there will be occasional three or two days. The amount of milk consumed is reduced, and it was a bad appetite. I don't want to eat. This is the baby's unique anti-milk phenomenon. He Mingjiao said that the period of babies may appear in the baby 3-4 months, and may also appear in about 6-10 months. There are many reasons for causing the baby to be tired of milk, but it can be divided into physiological anorexia and pathological anorexia.

Physiological anorexia has a short duration, most of which is two or three days. At this time, the baby's mental state is normal, and there will be no abnormalities such as fever, crying, etc. Parents do not have to worry.

Pathological anorexia is caused by the disease that the baby is unwilling to eat milk, some lactose intolerance, and vomiting, diarrhea caused by the phenomenon of malnutrition. The other is an acute infection. For example, thrush can cause oral pain. When children drink milk, they will feel pain and refuse to eat. Therefore, in addition to tired of breasts, there will be other abnormal performances, such as poor sleep, lack of energy, easy to cry, and even bloating, vomiting, fever or shortness of breath. Parents should pay attention to it and go to the hospital for medical treatment. The phenomenon, lactose intolerance can not be treated in time will cause infants and young children to be tired of milk, affecting their growth and development.

The consequences of calcium deficiency in newborns are relatively large, especially severe calcium deficiency, which can easily lead to neonatal rickets, new teeth, late teeth, irregular teeth, and anorexia eclipse, etc. Conducive to the growth of children.

Milk contains trace elements essential for the growth and development of human bones, muscles, organs, brains, etc. Because lactose intolerance can not absorb the nutrients in milk, infants and young children with malnutrition generally have various symptoms of malnutrition.

The galactose formed by milk under the action of lactase is an essential substance for the development of the baby's brain, and the long-term lactose intolerance affects the brain development of infants and young children.

At the same time, dry lactose is intolerant. After drinking milk, milk can not be completely decomposed, digested and absorbed in the intestines of infants and young children, and various harmful substances are formed under the action of bacteria. It causes intestinal flora imbalance. Causes gastrointestinal problems, long-term lactose intolerance can lead to chronic diarrhea that is difficult to cure in children; some children will induce diaper rash.

Lactose intolerance affects various minerals in milk. Such as the absorption of calcium, iron, and phosphorus. It causes the baby to be deficient in calcium, zinc deficiency, iron deficiency, and anemia.

   Lactose intolerance can also cause the growth and development of vitamins, proteins and other infants in milk, which are difficult to be digested and absorbed by children. It is suitable for children with low body weight and growth retardation. In severe cases, the complications induced by lactose intolerance may endanger the life of the child.

10. Lactose intolerance and infant health

Lactose intolerance refers to the lack of lactase in the intestines of the human body, which does not digest the lactose in the milk, resulting in bloating, abdominal pain, nausea, and other gastrointestinal symptoms after consumption of milk and dairy products.

11. Symptoms of lactose intolerance in breast milk

During the baby's feeding process, the mother often encounters various problems.  The experienced moms know that different situations will be dealt with in different situations, but for those who have just become treasure moms, they are often panicked during the baby's care. Especially when the baby has diarrhea, bloating and so on. Under normal circumstances, when the baby has vomiting, diarrhea, bloating and other adverse conditions, it is mostly caused by the baby's diet. Many mothers think that the baby is always breastfeeding. Breast milk is the safest food for the baby, so most mothers will not consider the baby's diet, but breast milk can also cause lactose intolerance. What is the performance of lactose intolerance?

 (1) Symptoms

The so-called lactose intolerance is that the nutrients in breast milk can not be completely absorbed by the baby's body. Many nutrients, such as glucose, cannot be decomposed by the baby's stomach. Such substances do not pass through the baby's small intestine but directly Enter the baby's large intestine, and then directly ferment by the action of the large intestine, resulting in a large number of acidic substances and gas production. In the face of such a situation, the baby will have abdominal pain, diarrhea, bloating and other conditions. In this case, we call it lactose intolerance.

Many newborns will develop lactose intolerance, which is due to the imperfect gastrointestinal function of the newborn, and the baby's stomach has not yet developed to maturity. At this time, if the lactose of the mother's breast milk is for the baby's stomach If it is not easy to absorb, it is easy to cause lactose intolerance. 3. When the baby is lactose intolerance, it usually shows abdominal pain, bloating, diarrhea, vomiting, odor, snoring, etc. In severe cases, the baby will be dehydrated. In normal times, the mother needs to observe whether the baby has such symptoms.

When the baby develops lactose intolerance, it will have a huge impact. Lactose intolerance will make the baby's body uncomfortable. At this time, the baby will often become dry and uneasy; it will also cause damage to the baby's stomach; Lactose intolerance, so the baby's diet will be affected, which will cause malnutrition in the baby; it will also affect the development of the baby's brain. Therefore, the mother must take appropriate measures when lactose intolerance occurs. The baby is relieved. Usually, the doctor will recommend the baby and the milk without lactose, but this will cause the baby to be malnourished, so the mother needs to adjust under the guidance of the doctor.

(2) The main symptoms and effects of lactose intolerance

The common symptom of infants and young children is diarrhea. The typical stool is yellow loose stool with foam and sour taste. Older children with abdominal discomfort, abdominal distension is more common. The symptoms of diarrhea disappeared several days after the lactose diet.

Secondary lactose intolerance causes diarrhea. If a child with breast milk or milk powder is main diarrhea, it will not be good for a long time. It is often necessary to switch to lactose-free milk powder before diarrhea can slowly improve.

(3) lactose intolerance symptoms:

When your baby has symptoms of lactose intolerance, small intestine spasms, abdominal pain, bloating, belching, and diarrhea may occur between 30 minutes and 2 hours of eating lactose-containing foods (such as breast milk or other dairy products). And other manifestations, of which diarrhea is the most obvious symptom.

Diarrhea caused by lactose intolerance has certain characteristics: daily diarrhea several times to more than 10 times, the stool is mostly yellow or blue-green, or egg-flower soup, foam, and milk. Because most of the children have more intestinal gas, they will have more fat, and often bring a small number of feces on the diaper, often a bowel movement.

Strange to say, some people with lactose intolerance can eat a small number of dairy products, while others will feel uncomfortable after eating even a little bit of lactose. You may think that lactose intolerance is similar to milk allergy. Milk allergy is a reaction of the body's immune system, and lactose intolerance is a problem of the digestive system. However, the symptoms of the two are very similar. For example, milk allergy or lactose intolerance may cause abdominal pain or diarrhea after eating dairy products.

Lactose is very important for your baby's growth and development. Because lactose enters the body, it can be broken down into glucose and galactose by the action of lactase in the small intestinal mucosa. Glucose supplies energy to your baby and galactose is an essential energy source for the development of your baby's brain. Besides, lactose produced by lactose fermentation can promote the absorption and utilization of trace elements such as calcium, phosphorus, iron, zinc, and phosphorus in food.

the-risks-factors-of-lactose-intolerance

Once the long-term lack of lactose absorption and utilization, the baby is prone to malnutrition such as weight loss, fatigue and the decline of immunity, which is not conducive to its growth and development. Therefore, once the baby is found to have lactose intolerance, it should be treated aggressively.

Studies have found that even patients with severe lactose intolerance, taking less than 6.5-12.5 mg of lactose per day, equivalent to no more than 125 to 250 ml of milk, and often do not cause symptoms when eating with other things.

Lactose intolerance is often related to the amount of lactose eaten. The intestine has a normal ability to digest a certain amount of lactose. When lactose exceeds this amount, it shows symptoms.

12. Teach you a scientific understanding of baby diarrhea caused by lactose intolerance

how-can-i-tell-baby-diarrhea

Lactose intolerance is due to less lactase secretion, also known as lactase deficiency. Lactase deficiency is a widespread worldwide problem. The incidence of the Far East population is high, and most people do not have symptoms. However, diarrhea and other symptoms often occur in neonates and infants with milk as the main diet.

The peak ages of lactose intolerance in different countries are different. Japan is 7-8 years old, Africa is 3~5 years old, and 1168 healthy children aged 3-13 years in Beijing, Shanghai, Guangzhou, and Harbin have investigated lactase. The incidence of deficiency is high, and 87% of children with lactose intolerance occur between 7 and 8 years of age.

The main symptom is diarrhea several times a day to more than 10 times, most of the children have more intestinal gas, often bring a small number of feces on the diaper. Most of the stools are yellow or blue-green, or egg-flower soup, foamy, with milk, and a few children have milk or vomiting. Because the effect of lactase is low, the child will be accompanied by bloating and varying degrees of uneasiness, easy to cry, defecation or improved diarrhea after treatment. Intestinal colic is rare and often occurs in the course of the disease, but it can also occur before diarrhea. In severe cases, dehydration, acidosis, growth retardation, etc. can occur, and there is no fever.

Pediatric diarrhea is a group of digestive tract syndromes characterized by multiple causes and multiple factors, which are characterized by increased frequency of stools and shape changes. It is a common disease in infants and young children in China. The high incidence period within 1-year-old is the main cause of malnutrition, anemia, and growth and development disorders in children.

In daily care, many babies will have diarrhea. There is a saying that lactose intolerance can cause diarrhea in the baby. But is this the case? Today, let us uncover the true causal relationship between “lactose intolerance” and “diarrhea”.

First of all, there are many reasons for baby diarrhea. For example, sudden changes in climate, disorders of the baby's gastrointestinal function, and infection with viral bacteria may be the cause of diarrhea. Diarrhea is prone to damage the baby's small intestine epithelial microvilli, resulting in a lack of secondary lactase. Lactose deficiency causes lactose to enter the large intestine and produce a large amount of gas, which causes the baby's intestinal tract and flatulence. At the same time, the unabsorbed sugar and fermentation products form a highly permeable environment, forming osmotic diarrhea, which causes the symptoms of diarrhea to increase. If the symptoms of diarrhea in the baby are aggravated, it will continue to aggravate intestinal mucosal damage and aggravate lactase deficiency.

Look at the so-called lactose, which is a kind of sugar contained in dairy products. It must be hydrolyzed by lactase to become two monosaccharides in the small intestine, namely glucose and galactose. Lactose-deficient people, after eating milk or dairy products, lactose in milk can not be completely digested and absorbed in the intestinal lumen, so that the osmotic pressure of the intestinal contents is increased, the intestinal emptying is accelerated, so that lactose is quickly discharged. The large intestine is fermented by the action of bacteria. Mild symptoms are not obvious, and heavier people may have symptoms such as abdominal distension, bowel, exhaust, abdominal pain, and diarrhea. Doctors call it lactose intolerance.

It can be seen that after diarrhea occurs, the small intestinal epithelium is damaged and the lactase is greatly reduced, resulting in the lack of secondary lactase, which leads to lactose intolerance. However, lactose intolerance caused by diarrhea will further aggravate the symptoms of diarrhea.

Therefore, when your baby has a condition that is difficult to improve with diarrhea, parents should pay attention to whether the baby is lactose intolerant.

When your baby has diarrhea, start removing lactose from the food, such as ordinary milk powder for your baby, to prevent the increase in lactose intolerance and prolong the course of your baby's diarrhea. At this time, the most simple and effective way is to replace the diarrhea milk powder with the lactose-free formula for targeted conditioning, and after the diarrhea is improved, adhere to the diarrhea milk powder for 2-3 weeks to consolidate the effect.

In the choice of diarrhea milk powder, pay special attention to the lactose content in the formula table. The national standard regulates the so-called lactose-free formula, that is, only lactose content below 0.5 g / 100 g of milk powder can claim "lactose-free formula."

  Pay attention to the difference between the lactose-free formula and low-lactose formula when choosing diarrhea milk powder. There are also some claims that the so-called "lowering lactose", in fact, the lactose content far exceeds the standard of 0.5 g / 100 g of milk powder, so should pay attention to choose to indicate "lactose-free formula" when buying milk powder.

13. Baby inexplicably crying may come from lactose intolerance

cry
baby cry

The genetics of lactose intolerance is located in the second pair of chromosomes of the human body. These genes cause a lack of lactase in the stomach, which prevents lactose from being completely digested in the stomach and produces too much hydrogen, which in turn causes flatulence.

Dr. Liu Mingfa explained that under normal circumstances, pregnant mothers are 32 to 38 weeks pregnant, the amount of lactase in the gastrointestinal tract of the fetus can be increased to 70% of the adult population. Postpartum feeding will continue to stimulate the development of lactase in the baby, at 4 months of age. Left and right, can develop mature. However, if the baby has lactose intolerance, feeding after birth can not stimulate the continuous production of lactase, 1 to 2 weeks after delivery, as the number of milk increases, you can find that the baby's milk is not smooth, symptoms include reduced food intake, flatulence Milk can not be fed, easy to overflow milk, diarrhea, slow weight gain, easy to cry during feeding.

If you can drink 90ml of milk in the previous 20 minutes, but after the symptoms appear, 90ml of milk needs to be fed for more than an hour, or it is very hungry, but the milk does not drink much, refuses to drink again, the number of bowel movements per day exceeds 10 times, etc. Must be suspected of lactose intolerance or allergy to milk protein. The symptoms of milk protein allergy are similar to those of lactose intolerance, but bloodshot is more likely to occur during defecation, and may also be accompanied by symptoms of vomiting and skin irritation.

Many babies with lactose intolerance symptoms in the early stage, because no real-time diagnosis and treatment, the side effects of lactase deficiency affect the digestive function (such as poor villi development, intestinal inflammation, etc.), but expand the child's gastrointestinal problems or affect the stomach Development, long-term may cause children persistent malnutrition, slow growth, colic or emotional problems (often crying because of discomfort).

(1) Breastfeeding with probiotics

For infants and young children, to meet the developmental needs, on the one hand, we must consider balanced nutrition, on the other hand, we must give enough calories. Take breast milk tailored to your baby as an example. The average 100ml of breast milk contains 7 grams of lactose, which is specially used for the growth and development of your baby. Besides, the lactose in breast milk is accompanied by sialic acid, oil, and other substances that are beneficial to brain development, so that the baby can help the brain to develop while supplementing energy.

On the whole, breastfeeding has a great health benefit for the baby, so even if the baby has symptoms of lactose intolerance, most of the doctors will encourage the mother to continue breastfeeding, with probiotics and anti-flatulence drugs, or directly The addition of lactase to breast milk allows mothers to continue breastfeeding before the child is 1 year old (in the stage of milk-based diet). If the baby's diet contains formula in addition to breast milk, the formula should be changed to lactose-free milk powder, and the ratio of breast milk to formula should be adjusted according to the degree of lactose tolerance and improvement of the child.

(2) Pay attention to the diet and seek medical treatment at the right time

If the symptoms of baby lactose intolerance persist and are not treated, the villus tissue may be underdeveloped, which may lead to allergies to milk proteins or skin problems such as eczema or skin irritation. At this time, it is necessary to choose a mixed formula of lactose-free and hydrolyzed protein to replace the milk powder, to help solve the baby's gastrointestinal problems.

The lactose-free formula usually uses maltodextrin or corn syrup instead of lactose to supply the calories your baby needs. This formula does not replace the benefits of other active substances in breast milk, but it allows the child to Relieve symptoms and restore gastrointestinal function with adequate calorie supply. Clinically, about 80% of lactose intolerant babies can return to a normal diet after changing the lactose-free formula.

The gastrointestinal tract is an important part of the body's immune system. A healthy gastrointestinal tract is responsible for the healthy development of the immune system. It may even solve the baby's skin allergies, colic, and difficulty in sleeping and emotional restlessness. Therefore, it is recommended that if a newborn has a dietary problem, it is necessary to seek the diagnosis of a pediatric gastroenterologist early, find an appropriate method to prescribe the right medicine and avoid delaying treatment due to subjective judgment.

And for lactose intolerance, let's learn about it today.

I wonder if you have uncomfortable after drinking milk? For example, stomach swelling, diarrhea, etc., this is what we call lactose intolerance, due to insufficient lactase secretion, can not completely digest the decomposition of lactose in milk. Breast milk and dairy products are the main source of food and energy for infants and young children. Lactose is an important nutrient in mammalian milk. Lactose enters the human body and is decomposed by the action of lactase to be absorbed and utilized by the body. Loss of lactase or decreased activity can lead to lactose malabsorption, which causes a series of manifestations of the bowel, bloating, abdominal pain, and diarrhea called lactose intolerance.

Premature babies are more prone to lactose intolerance, and their intestinal system is not fully developed, called "developmental lactase deficiency." However, this condition usually only lasts for a short time, and most premature babies can drink lactose-containing formula and breast milk after they grow up.

There is also a situation in which the baby has "congenital lactase deficiency", which is a very rare genetic disease. The baby can't break down the lactose in the breast milk or the formula, so they can only be lactose-free. Infant formula, otherwise severe diarrhea, dehydration, and weight loss will occur.

14. An effective shortcut to supplement lactase to prevent lactose intolerance

Lactase is a digestive enzyme secreted by small intestinal cells and functions to digest lactose. Lactase deficiency causes lactose digestion and absorption disorders, and a series of clinical symptoms such as bloating, abdominal pain and diarrhea are called lactose intolerance.

 Lactose intolerance - not only affects life but also causes nutrient deficiency. Lactose is mainly found in milk and its products. The lactose content in milk is about 5%, and the lactose content in breast milk is 7%, except for breast-fed infants. The lactose ingested by humans is all derived from milk and its products. Therefore, lactose intolerance refers to milk lactose intolerance. Lactose intolerance not only affects the absorption of lactose in milk and its products but also causes gastrointestinal discomfort. It can reduce the absorption and utilization of protein, calcium, iron, vitamin B12 and other nutrients in milk and other foods that are ingested at the same time as milk, resulting in a lack of nutrition.

Therefore, finding a simple, safe and effective method to prevent lactose intolerance is of great significance for improving the nutritional status and health of these people. Add lactase - easy to drink milk, improve symptoms.

Recently, we added lactase to 41 lactose intolerant volunteers to understand and observe the therapeutic effect on lactose intolerance. The subjects were 19-79 years old, including 15 males and 26 females. The test method was as follows. Under different conditions, the subjects were given milk 2 times and the results were observed. For the first time, 300 ml of whole milk was given on an empty stomach. Lactase was not added. After one week, the same amount and brand of milk were consumed for the second time. A lactase tablet was taken orally 5 minutes before drinking milk. Lactase 60 mg). The effect of lactase was evaluated using the urinary galactose test method and the lactose intolerance symptom scoring method.

The results showed that all subjects who did not receive lactase before drinking milk were positive or weakly positive for the galactose test, and 28 (68.3%) had symptoms of lactose intolerance, and the severity of symptoms was different. Most of them appear within two hours after drinking milk, which is manifested as abdominal distension, diarrhea, hernia, bowel, and anal exhaust. Among them, 14 (33%) had increased stool frequency and diarrhea. Symptoms slowly relieve themselves after some time. The longest-lasting until the morning of the second day has a certain impact on life and health. Then, before the second drinking after one week, 41 lactose intolerants were supplemented with 1 piece of lactase. After that, 36 people had urinary galactosidase from positive to negative, and 4 were urinary galactosidase. From positive to weak positive. The total effective rate was 97.6%.

The experiment showed that after lactase supplementation, all people had complete disappearance of lactose intolerance within 2 hours, but 3 people still had mild symptoms of lactose intolerance within 2-24 hours. The reason may be that these people are seriously deficient in lactase, and lactase 60 mg is not enough to completely decompose lactose in 300 ml of whole milk. It is concluded that if lactose intolerance is severe, oral lactase should be appropriately increased. The dose, or reduce the amount of milk (about 200 ml each time). In the trial, no lactase was found to be caused by any side effects. Lactose intolerant can take lactase preparation before or during drinking, which can directly help lactose digestion and absorption, prevent lactose intolerance, and improve the absorption of protein, calcium, phosphorus and other nutrients in milk. Utilization is a simple, effective and safe method of prevention and control.

15. Human beings cannot wean for life

Children grow up to be weaned off, which is our traditional eating habits, in fact, this practice is not scientific. Studies have found that weaning affects calcium uptake to a certain extent and bone development in the near future.

A six-month follow-up survey of 474 7-year-old and 9-year-old pupils in Shenyang was conducted by the School of Health of China Medical University. It was found that the height of students who drank 400 ml milk per day increased by 0.72 cm and 0.46 cm, respectively, compared with those of the control group who did not drink milk. In addition, the weight and bone mineral density of the children who drank the milk also increased significantly.

The main terrain of Europe is plain, with a small population and a large area. The climate is mainly temperate marine climate, which is suitable for forage growth and animal husbandry development. In the areas where animal husbandry develops relatively fast, cheese production develops relatively fast. (Typically cheese-rich Western European countries: France, Italy and the Netherlands)

European latitude is higher, dairy meat food is high in protein and calorie, which can quickly provide energy for the body to withstand the cold. Animal husbandry produces a large amount of fresh milk, which can not be consumed, making cheese for a longer time to preserve. The more you do, the bigger you get, and eventually, it becomes indispensable to the whole people from the Royal family. As a result, Europeans rely on dairy meat.

Genetically speaking, we can basically say that the Chinese around you are lactose intolerant.

Both in Europe and Asia, primitive humans were lactose intolerant genotypes. High lactose tolerance is a characteristic that has evolved gradually in human milk-drinking history, which is not very long.

About 11,000 years ago, herdsmen in West Asia domesticated dairy animals (sheep) and began using dairy products. But the genes for lactose tolerance did not appear in Hungary's vast, fertile plains until about 7,500 years ago. In order to reduce the problem of lactose intolerance, the ancient nomadic people invented various fermented dairy products, such as yogurt, cheese, through lactic acid bacteria fermentation, part of lactose into lactic acid.

After several thousand years of evolution, lactose tolerance has reached over 80% in Europe, North America and Central Asia. In Poland, this evolution from 0 to 80 percent took only 130 generations. The explanations given by evolutionary biologists are:

People with lactose tolerance genes are more likely to consume nutrients, and their offspring are 19% higher than those with lactose intolerance. Lactose tolerance genes have thus become "the most powerful genes found in the genome so far".

So why don't the Chinese have this gene? Because we don't drink milk. So there is no such powerful natural selection.

In the Neolithic Age about 10,000 years ago, the ancestors of different parts of Eurasia began to produce agricultural products and domesticate livestock. The purpose of domesticating livestock is to obtain a stable and reliable source of food. Apart from dogs, most domesticated livestock is used for food.

The climate in West Asia is dry and hot, and the terrain is mainly plateau and mountainous areas, which is suitable for the development of animal husbandry. Cattle and sheep have become the main livestock in West Asia. The Chinese civilization originated from the alluvial plain of the Yangtze River Basin in the Yellow River, suitable for grain cultivation, and the pig with the wider diet became the first choice. Compared with cattle and sheep, pigs produce little milk, have short lactation period, and have difficulty in collecting (nipple). They are not qualified dairy animals.Killing meat is more cost-effective. Buffalo and buffalo, which helped farm, did not appear on a large scale until the Bronze Age, four or five thousand years later than in Western Asia.

Because of the differences in dietary habits, it also leads to differences in body shape. Europeans are indeed much stronger than Asians in eating meat and drinking milk. This also explains the low-carbon and high-protein diet mode advocated by the fitness circle at present, that is, the way foreigners eat, so the form of fitness meals is also the majority of Western food.

The human skeleton is the "warehouse" of calcium storage, which is rich in stock and benefits all one's life. In the past, experts generally believed that before the age of 30 is a good time to supplement calcium, but now they emphasize that childhood is the most important! Nowadays, many young women do not pay attention to drinking milk at ordinary times. When they enter pregnancy or lactation, they drink milk in large quantities. They think that this can meet the growing needs of fetuses or infants, and also reduce the excessive loss of calcium from mothers.

However, the study of "Nutrition of milk to breast-feeding mother's bone" in Tongji Medical College of Huazhong University of Science and Technology reveals that this is not helpful, because the bone quality of those who increase milk consumption is not better than those who do not drink milk, and women who have milk-drinking habits have the least bone calcium loss. The study further confirmed that the effect of drinking milk on improving calcium nutrition is long-term, and can not be a quick success and instant benefit.

Relevant experts stressed that in the future, we should not publicize "weaning" unilaterally, but cultivate the habit of drinking milk for life. From the point of view of nutrition and health improvement, "drinking milk every day, benefiting for life, health for generations, national prosperity" is our goal.
