    ?

    However, Chu Lihua must not go on like this all the time.

    Therefore, Liu Xingting thought for a while, and then said, "Aging, which everyone will encounter, is even more difficult. On the surface, aging is the gradual loss of vitality and elasticity, and the body's self-repair ability declines.

    But in the end why people age, there are about 300 different hypotheses.  To sum up, there are generally three types of views. Some people think that aging is due to genetic mutations, some people think that the body is gradually depleted, and some people think that cells accumulate toxic byproducts.

    But no one knows what the reason is.  Perhaps all three factors worked together, or it was possible that any two of them were side effects of a third remaining factor.

    Our bodies are a mass of mysteries, and often when we think we have solved one, we discover ten new ones.

    We still have no way to understand our own brains, how memory and perception are produced.  There is no way we can create artificial blood, even if blood looks simple.

    We know that our liver can grow back after being cut in half, but how exactly this process works, we have no clue.

    We've learned a lot about the human immune system, but we still haven't been able to explain why some people develop allergies.  For some diseases, we don't even understand it.

    For example, Huntington's disease, which is a rare genetic disease, causes people to develop the disease in middle age and die in agony after suffering for more than ten years.

    We know it's because of a mutation in a gene that makes a protein called huntingtin.  This protein is the largest and most complex of its kind in the human body, but what it does is still a mystery.

    As we explore our own bodies, the mystery will always be solved one day.  And these solved puzzles often subvert our past cognition.

    For example, this is the relationship between us and microbes.

    Our bodies, in addition to containing ourselves, are home to trillions of tiny living beings.

    In the past, we didn't know much about the microbes inside and outside the body, and we often studied the germs and viruses that cause disease.  However, there are not many types of pathogenic microorganisms.

    There may be 40,000 kinds of microorganisms inside and outside our body, about 36,000 kinds in the gastrointestinal tract alone, more than 1,000 kinds in the mouth, and nearly 1,000 kinds in the nostrils.

    As the research progresses, this number is still increasing, and the types of microbes are not exactly the same for everyone.  Age, where you live, and even whether you're lean or obese can mean completely different microbial combinations.

    The total weight of microorganisms carried by each person is about the same as that of the brain, and the number is about 30 trillion to 50 trillion, which is about the same as the total number of cells in our body.

    Some have even started describing the microbiome as an organ of ours.  "

    These knowledge, which is common sense to medical staff, is indeed extraordinarily creepy to Chu Lihua, "Is that much?"

    Liu Xingting nodded, "It's actually nothing. It's like the probiotics, yogurt, stinky tofu, and sweet liquor you like to drink. There are many microorganisms.

    These tiny lives have brought us a lot of benefits.

    Microorganisms help us decompose food that we cannot directly use, providing about 10% of calories; they also extract beneficial nutrients, such as vitamin b2, b12 and folic acid.

    We can produce 20 kinds of digestive enzymes in our body, but the number of enzymes produced by bacteria is 500 to 1000 times that of ours.  Without all kinds of microbes in our bodies, our nutrition would be greatly reduced.

    Although we don't realize it, the body is primed for microbes.  This work has been going on since we were born.

    We can probably assume that a baby leaves the womb sterile, but as it passes through the birth canal, it is exposed to the microbes in the mother's body that become the baby's first inhabitants.

    And babies born by caesarean section do not go through this process, which may have a profound impact on the health of newborns.

    Many studies have shown that people born by caesarean section have a greatly increased risk of type 1 diabetes, asthma, celiac disease, and even obesity, and even an eight-fold increased risk of allergies.

    We don't yet know why babies get such long-term differences in whether they acquire their mother's microbes.  "

    This actually surprised Chu Lihua, "So there is such a big difference between a caesarean section and a natural delivery?"

    For Chu Lihua, the beginning andAfter communicating with himself, Liu Xingting became more and more satisfied, "Yes, many of them are gifts from nature to life, but we haven't fully understood the principle yet.

    What we do know, though, is that mothers are primed not only to nurture their babies, but also to take care of their babies' microbes.

    There are more than 200 kinds of sugar substances in the mother's vagina that the baby cannot digest, and these are completely prepared for the microorganisms in the baby's intestinal tract.

    When these microorganisms live happily, the baby's body will be good.

    So you see, although there are still many unsolved mysteries for us, our bodies know how to take care of themselves.  "

    Chu Lihua was stunned, "Xiao Qi grew up drinking milk powder, so could it be because of"

    ¡ª¡ª"It can only be said that the resistance will be weaker. As for Xiaoqi's condition, let's talk about it after a careful examination in Beijing.

    Chuchu, what you did to her was really good.  "

    Chu Lihua shook her head, "It's all my fault, if I"

    Liu Xingting quickly interrupted her, "Chuchu, you can't think like this anymore, you treat Xiaoqi better than the twins."

    No matter how much it is, it is hard to say here.

    Chu Lihua was silent, and Liu Xingting hated himself for talking about something he was familiar with.

    For this, he was very annoyed, it was really a waste of previous efforts.

    Let's stop talking, the atmosphere is awkward; let's talk, I'm afraid that there will be something that will make Chu Lihua blame herself again.

    Unexpectedly, when Liu Xingting was struggling, Chu Lihua took the initiative to speak: "Xingting, tell me more about your body."

    ¡ª¡ª"Okay, then let me talk about how we should live a healthy life.

    The first thing we need to know is that because of the advancement of medicine and medical technology, we may be living in the best of times today.

    Over the past eight decades, life expectancy for men has increased from 48.1 years to 70.5 years today; for women, it has increased from 52.9 years to 75.6 years.

    At present, there are more than 20 countries and regions in the world with a per capita life expectancy higher than 80 years old, and the Hong Kong region of China tops the list at 84.3 years old.  "(Remember this site URL: www.hlnovel.com
