School is about to start, many mothers are worried that their children are easy to be cross-infected after going to school, what should I do? Is there any way to improve resistance?
When it comes to this topic, lactoferrin, bovine colostrum, probiotics, vitamins, and prescription drugs - immunomodulators (spleen aminopeptide, bacterial lysate, etc.).
Every time we see mothers saying that it is useful, we can't help but be moved in our hearts, thinking about whether to give ourselves a little baby. But looking at the price, it is not cheap.
So, are they really useful? Is it an IQ tax? Today, let's have a good chat~
Lactoferrin
May be useful, but it is not recommended to buy it separately
Lactoferrin has biological health implications, and some countries approve the addition of this substance to infant formula. However, lactoferrin itself has biological health significance, and does not mean that eating lactoferrin directly can bring health gains or enhance immunity.
On the market and in TV commercials, there are always products that claim to improve or strengthen your child's immunity or resistance. In fact, no food or dietary supplement has been found, and healthy people eat it, and their resistance is enhanced.
In addition, the human immune system is very complex, not that the stronger the immunity, the less you will get sick. For example, allergic diseases are caused by the wrong immune response of the human immune system to some non-pathogens, which is commonly understood to be that the human immunity is too strong and excessive, which leads to the problem.
The "working principle" of the human immune system is complex, and it is not as easy as adjusting the balance, which can be easily manipulated by humans, so there is no "shortcut" to change the human immune system at will according to your own wishes.
So, if you want your child to get sick less, we can't expect to eat "resistance-enhancing supplements", what we can do is:
1. Breastfeeding;
2. Vaccination according to the procedure;
3. Healthy and balanced diet, moderate exercise, adequate sleep;
4. Wash your hands frequently.
Bovine colostrum
Useful for calves, uncertain for children
Let's start with the conclusion:
- Bovine colostrum is the best and very critical food for calves after birth, not people.
- Bovine colostrum has great benefits in theory, as well as for people.
- However, in the current practical application, bovine colostrum has no clear benefits for digestive tract infections, which may prevent and alleviate respiratory infections, and no evidence has been found to enhance immunity.
- Colostrum products are not recommended for children.
- But the function of bovine colostrum will definitely have, but we have not studied clearly, and when the research is understood later, the prospect of bovine colostrum should be great.
As early as 2012, the Ministry of Health made it clear that "bovine colostrum and dairy products made from bovine colostrum must not be added to infant formula." ”
This rule was once known as the "cow colostrum ban", and the king of immunity, "bovine colostrum", has since walked down the altar. But I have to say that this word "forbidden" is actually not very accurate.
The state only "prohibits the addition in infant formula (that is, infant milk powder)", not "prohibits the addition in food". Some milk shells, milk tablets, milk sticks with some colostrum, it is still okay, as snacks occasionally eat is okay (children under 1 year old do not eat).
Can improve immunity? Don't take that risk!
Bovine colostrum has complex ingredients, is it safe to consume for a long time? This has to be a big question mark~
Probiotics
It can be eaten when diarrhea
At present, probiotics have only been confirmed to have a clear effect -
Prevention or relief of acute diarrhea, as well as diarrhea caused by antibiotics.
Some products will advertise that with the addition of probiotics, the baby will eat less sick.
This is a bit metaphysical. In fact, the added probiotics, whether in type or quantity, are too small compared to what exists in our bodies! It is not easy to survive the intestines and improve diarrhea, but also play a health role elsewhere? It's a little hard to be "bacteria"~
vitamin C
Food supplement is enough, high-priced vitamin C eat carefully
Many families will stock up on vitamin C supplements and effervescent tablets in their medicine boxes, and even people in pharmacies say that eating these can improve immunity.
We also do not deny that moderate vitamin C supplementation is beneficial to the body, but it is not enough.
For 1~6-year-old children, the recommended daily intake of vitamin C is 40~50mg.
Eating 1 winter date or 1 kiwi is basically enough, plus other vegetables and fruits, most of them have surplus~
Immunomodulators
Useful, but not necessarily needed by your child
If your baby always has respiratory infections (colds, rhinitis, inflammation of the tonsils, etc.) more than 6 or 7 times a year (more than 2 pneumonias), the doctor may recommend that you try - immunomodulators.
The immunomodulators commonly used by pediatricians are mainly bacterial lysate, spleen aminopeptide, and pidotimod. Among them, the recommended level of bacterial lysate is the highest.
▲The "Expert Consensus on the Clinical Diagnosis and Treatment Management of Recurrent Upper Respiratory Tract Infections in Children" pointed out that bacterial lysates can effectively prevent recurrent upper respiratory tract infections in children.
Bacterial lysates are actually oral lyophilized powder after the dissolution of several common respiratory bacteria, and the principle is a bit like vaccination.
▲Drug instructions
Professor Wang Huiying, deputy director of the Department of Allergy of the Second Affiliated Hospital of Zhejiang University School of Medicine, also vividly compared bacterial lysates to "playing with mud":
Just like before, many children will play with mud, microorganisms are exposed, and the immune system is trained to mature and develop rapidly. In modern life, everyone's microbial exposure has decreased, because there are fewer microorganisms in contact, and immune maturation will progress slowly, which is actually one of the reasons for the increase in allergies, asthma and other diseases.
By inactivating pathogenic microorganisms, bacterial lysates expose the immune system to more pathogens, promote immune system maturation, significantly increase immunoglobulin levels, and reduce the chance of infection.
However, the controversy of immunomodulators is also relatively large, such as it is oral, why can it act on the respiratory tract after entering the digestive tract? Will it cause immune disorders, increase the risk of allergies... More strong, high-quality evidence is needed.
Babies often get sick, is it because of weak immunity?
Yes, babies are always sick, that is, "weak immunity", but this weakness is normal relative to their age.
After the child's immune system is born, its development is mature, that is, the immune organs and immune cells are quite mature.
However, because it has no experience, although it should have everything, its function is still not enough. For example, it is the difference between recruit eggs and elite soldiers in a hundred battles, although there are also guns, but the combat effectiveness is not comparable at all.
After most children are 6 months old, the antibodies transmitted from the mother to the child through the placenta will gradually be consumed, their own "immunity is weak", and the child's range of activity expands, and begins to face the external environment (viruses and bacteria) independently, of course, various infectious diseases will gradually appear.
Current research has found that healthy children under the age of 6 will catch a cold 6-8 times a year on average, and children who have just entered kindergarten or have older siblings who have attended school at home will have 10-12 times a year. From September to April, the infection is high, reaching 1 time in January, and each time may last for 2 weeks.
In this way, a healthy child, may be sick for half a year of the year, but this is not abnormal Oh, does not indicate that the child has low immunity or defects.
What are the circumstances that indicate an immunodeficiency in your child?
Immune deficiency, in layman's terms, is a problem with the immune system, the main features are:
- It cannot defeat various pathogens, such as bacteria or viruses, and once infected, it is difficult to recover.
- Failure to identify problematic cells in the body, and if these cells cannot be destroyed, abnormal replication will occur, leading to problems such as cancer.
- Failure to recognize normal tissues can attack body tissues, leading to autoimmune diseases such as lupus erythematosus and rheumatoid arthritis.
Therefore, there are 3 characteristics of immunodeficiency diseases: infection is always bad, tumor is high, and autoimmune diseases are susceptible.
If the child has 2 or more of the following clinical manifestations, be alert to immunodeficiency disease:
- 1-year middle ear infection order >4 Next
- Severe sinus infections > 2 times within 1 year
- Antibiotic therapy for 2 months does not respond well. Note: Haha, few of this can achieve it, don't babble with antibiotics for a few days
- Pneumonia > 2 times in 1 year. Note: Must be real pneumonia, now in some places the diagnosis of pneumonia is too broad, take a film to suggest that the lung texture is thick to say pneumonia, some too much
- Infants and young children do not gain weight or are extremely stunted with growth and development
- Recurrent deep skin or organ abscesses
- Persistent thrush or fungal infection of the skin. Note: thrush within one year old, recurrence after irregular treatment is not counted, how to standardize the treatment of thrush, please see the article: The family is disinfected every day, and the baby has white hair in his mouth! (Thrush)
- Intravenous antibiotics are required to clear the focus of infection. Note: Oral administration for a few days is fine, not counted
- Intractable infection at ≥2 (including sepsis)
- Family history of primary immunodeficiency disease. Note: For example, there are relatives in the family who died in infancy or diagnosed defective diseases
In addition to the above manifestations, if the child has the following problems, it is also necessary to consider:
- Serious complications occur after receiving live vaccines (e.g., chickenpox, BCG, etc.).
- Persistent lymphopenia (lymphocyte count < 1500/microliter in patients over 5 years of age, < 2500/microliter in young children)
- Unexplained fever
If you don't have the above performance, don't think about immune deficiency.
Children continue to grow, the immune system continues to undergo the baptism of various viruses and bacteria, and constantly produces corresponding antibodies, about 10 years old, reaching the immunity of adults.
Therefore, don't be anxious, if the child is sick at home if you are not sure about the situation, seek medical attention in time, follow the doctor's advice, do not give the child "medicine" casually, the "miracle medicine" that can immediately improve immunity does not exist.
