Could the absence of good bacteria lead to an increase in allergies? ③ [Excerpt from Lecture & Consultation Session]
This article is an excerpt and edited version of the lecture "Ask Wahaha Sensei: Thoughts and Approaches to Children's Illnesses" held in 2018.

We are made of bacteria and viruses!
It is said that if we trace our ancestors back far enough, they originally came from bacteria.
Not only that, but our bodies also contain many remnants of what were once bacteria and viruses.
Now, in high school biology textbooks,Endosymbiotic TheoryThis has been reported.
In simple terms, each of our 37 trillion cells has a nucleus, and around the nucleus are organelles.
There are various things, and one of them is mitochondria.
Mitochondria are the factories that produce the energy sources we need to function.
ThisMitochondria were originally bacteriaThis is known as the endosymbiotic theory.
Bacteria enter our bodies, and what was originally bacteria gradually becomes human.
Bacteria and viruses from outside can enter our bodies and continuously evolve to survive within us.
It has finally become a part of our bodies.That's what it means.
Antibiotics kill gut bacteria
One of the reasons for the increasing number of allergic diseases today is
It is said that this may be due to the overuse of antibiotics during childhood..
Antibiotics are taken to fight bacteria, but they also end up in your gut.
Reduces the beneficial bacteria in our bodies that are known to protect us.It is.
It has been suggested that the decrease in Helicobacter pylori may be due to the overuse of antibiotics.
For this reason, do not use antibiotics for colds in young children.
has become something thatis now being said.
We have begun to reconsider children's medications, including antibiotics.
ThenMost of the medications said to treat colds are unnecessary.
It has become clear that the harm outweighs any benefits..
This shows that even if we reduce the medication, the healing process remains the same.
Children have an incredible natural healing ability.I realized that it is something.
The Case for Unconventional Parenting
Have you heard of the term 'hygiene hypothesis'?
The history of post-war medicine is primarily a battle against infectious diseases, including those caused by bacteria and viruses.
There, bacteria and viruses are seen as harmful, and the goal is to defeat and conquer them.
I have worked towards my goals.
Thus, we use two weapons against infections and bacteria: antibiotics and vaccinations against viruses.
While it is said that we have largely conquered it, various exceptions have emerged, and now we are in the process of reevaluating that.
The 'hygiene hypothesis' suggests that being overly clean in childhood can increase the likelihood of infections and allergic diseases.
That's what it is.
For example, soil is a treasure trove of bacteria.
Mr. Shinya Yamanaka received the Nobel Prize in Physiology or Medicine for discovering a bacterium found in the soil.
There must be so much about soil that we still don't understand, yet it is incredibly beneficial to us.
Recently, there has been a trend promoting unsanitary parenting practices.
I sometimes get asked how dirty I should be.
There is no need to be deliberately unclean; essentially, it means not to constantly emphasize "cleanliness."
I believe that so-called sterilization is harmful and unnecessary.
It's better to address foreign objects early on.
Our bodies have the ability to distinguish between foreign substances and those that are not foreign, as well as what should not be considered foreign.
Everything that enters the body immediately after birth is considered a foreign substance, but it is uncommon to reject breast milk.
The intestines assess what comes in, absorbing what is necessary for nutrition.
We make the judgment not to absorb what we perceive as foreign objects,
It is likely that we have something like a computer within our bodies that holds an immense amount of data.
I think this is about giving orders like 'put this in' or 'take that out.'
The acceptance of foreign substances is referred to as immune tolerance.
We have come to understand that this power is more active when we are younger.
Until now, I had been delaying the introduction of allergy-prone foods, but it's actually better to start incorporating them early on.
This means that you need to start with just a small amount, but the sooner you begin, the easier it will be to be accepted.
For example, comparing children who have pets at home since birth to those who do not,
It is almost certain that children who had pets are less likely to develop animal allergies as adults.
It's important to get accustomed to it from a young age.
In that sense,It's best to come into contact with soil, which is a treasure trove of bacteria, as much as possible.
Playing outside and being active boosts your immune system.
Even when you're sick, if it's a mild illness, it's usually better to stay active as it can boost your immune system.
I believe that not overly restricting or coddling them, and allowing children to do what they want, ultimately leads to better outcomes.
