Seafood, skewers, barbecues, crayfish, snack stalls...
Speaking of this, I believe that everyone has unconsciously left saliva.
But what you don't know is that although the stomach and mood are cool, they will also cause a variety of strange and strange pathogenic parasites to enter the human body.
Not long ago, there was a news report that a 4-year-old boy took out more than 1,000 milliliters of parasite-containing liquid in his stomach, and it was chilling after watching it.
It's just a meal, how can there be worms in the stomach?
What exactly are the bugs that stir up trouble in the human body? How does it enter the human body? Today, let's take a look at it with Xiaobian.
<h1 class="pgc-h-arrow-right" data-track="17" >", "pests" in pork, crayfish, and seafood</h1>
The phrase "roundworm in the stomach" is believed to be heard by everyone, and this is used as a metaphor for knowing the mental activities of others very clearly.
But in life, roundworm parasitism in people's stomachs is not a good thing.
The harm of roundworms should be deeply appreciated by people who grew up in the countryside.
I don't know what the reason is, many people often have loss of appetite, nausea and vomiting, malnutrition, and some people even have abdominal pain, blood in the stool, and urticaria.
In this case, most of them are infected with roundworms, and they need to go to the epidemic prevention station regularly to eat insect repellent drugs in order to completely eliminate roundworms in the body.
Roundworms are just a parasite.
It is estimated that more than 50% of the 7.7 million known animal species on Earth are of the same kind as this pathogenic organism that inhabits the human body.
Humans are the breeding ground and host of more than 100 species of parasites.
Depending on the environment in which these parasites parasitize, we can roughly divide them into:
Digestive parasites, intra-cavity parasites, intrahepatic parasites, etc.
In daily life, there are four main types of common parasites: roundworms, tapeworms, pinworms and hookworms.
How do creatures as obvious as bugs enter our bodies?
As the saying goes, disease comes from the mouth, and the biggest reason why parasites are fortunate enough to survive in our bodies is that they don't keep their mouths shut.
Because most parasites are eaten by us...
Shrimp and crab are probably the most popular foods for us.
Freshly baked crayfish and hairy crabs are roasted and fried on the table by the teacher, and spicy, spicy, spicy and sour flavors take turns in the mouth.
I believe that no matter who it is, it is impossible to resist the temptation of not eating crayfish and hairy crabs for a year!
But did you know that unhygienic shrimp and crabs may contain the parasite lung trematodes!
Ordinary cleaning, or soaking in wine, vinegar, or boiling water, does not necessarily kill them.
Lung flukes mainly reside in the lungs, and symptoms such as cough, chest pain, and dyspnea occur after infection, and some patients may have complications such as pleural effusion, pleural thickening, and empyema.
Therefore, when eating crayfish and hairy crabs, we must not go to places with dirty and messy sanitary environments!!!
Most people have a habit of eating food stalls, and there is one dish that everyone has ordered: field snails.
Because of its unique taste, in small restaurants, on the ground stalls and even on the dining table, there are always some people holding toothpicks and eating snails.
But this food, which everyone loves, is also inhabited by a parasite called Guangzhou Tube Roundworm. And the trouble is that because of the hard shell, the parasites inside the snails are more difficult to kill.
Tubeworm mainly parasitizes the body's central nervous system and can invade human nerves.
If infected with Guangzhou Tube Strongiasis, mild cases cause headache, dizziness, fever, neck stiffness, facial nerve paralysis and other symptoms, and severe can cause disability and death.
Therefore, eat the snails as much as possible to buy themselves, soak in salt water for 2 to 3 days after cleaning, to ensure health and safety.
In recent years, Japanese cuisine has become popular, and Japanese restaurants selling sashimi and sushi in many Chinese cities have become more common.
Sashimi is an indispensable dish in Japanese cuisine and is loved by many people. But what you don't know is that sashimi may also carry a parasite called liver flukes.
This insect will live in the liver to cause liver damage, mainly manifested as liver area pain, liver enlargement, indigestion, loss of appetite, abdominal pain and other symptoms, severe infection may occur cirrhosis or even death.
Adults of liver flukes can parasitize in the bile ducts for up to 20 to 25 years. When there are too many insect bodies, dead insect bodies, eggs and mucin block the bile ducts for a long time, and can also cause biliary cirrhosis and bacterial infections.
Studies have shown that the risk of cholangiocarcinoma in patients with liver fluke infection is 4.5 to 6.1 times that of non-infected people.
So listen to the editor's advice: eating sashimi is like opening a blind box, you never know whether there is a squirming parasite in the next bite.
There is also a food that has parasites, that is, pork that we eat every day.
Pork may contain pork tapeworms, and the "rice pork" that has been reported in the news refers to pork containing cysticercosis (the larvae of the pork tapeworm).
Pork tapeworm has a long lifespan, up to more than 20 years, perennial hermitage in the human body can cause indigestion, abdominal pain, diarrhea, blindness, fatigue and other dangers, but also affect the normal development of children, suffering from tapeworm disease.
Therefore, when choosing pork, be sure to go to a regular supermarket, and don't be greedy and cheap to buy those low-priced pork!
If you find something similar to a white grain of rice on the surface of the pork, don't buy it, and directly complain to the police!
Now it seems that although there are many delicacies, we are not paying attention to it a little, and we are taken advantage of by "parasites"!
<h1 class="pgc-h-arrow-right" data-track="246" > two, the arduous road of "soft rice"</h1>
As the saying goes, happiness is the result of struggle, and as a new youth of socialist thought, we should be proud of our struggle.
But the soft bones of the parasite are proud of "eating soft rice" and are ashamed of their struggle!
According to research, parasites, the behavior of living in other people's bodies to eat and drink, have been going on for hundreds of millions of years!
Zhang Zhifei's team from Northwestern University once found a special fossil in Yunnan, 512 million years ago, in which some tubular structures were attached to the shell of the brachiopod fossil.
Through research and speculation, the team found that these tubular structures were not the animals themselves, but an unknown parasite.
The days of opening the mouth and the clothes coming out are good, but this is also the consequence of the desperate efforts of generations of parasites.
We humans are exposed to a large number of microorganisms and parasites in various ways every day, such as unclean food, water and so on.
When they enter the human body, they need to go through a full 4 difficulties to live a worry-free life.
The first challenge the parasite encounters is the body temperature of the host.
The body temperature of the thermostatic animal is a big challenge for the parasite, not to mention the poor adaptability of the eggs.
Parasites that can live a soft meal life must adapt to the high temperature living environment in advance.
The second challenge is the activity of the gastrointestinal tract of the host.
Our stomach and intestines secrete digestive juices and digestive enzymes depending on how much we eat, and some parasites will be destroyed in the process.
The constant peristalsis of the intestine will also excrete some parasites from the body.
Therefore, the parasite also needs to evolve strong athletic ability or suction cups, small hooks and other equipment to prevent themselves from being driven out.
For example, the tapeworm is attached to the host's intestine through suction cups and small hooks, making its position stable and worry-free!
The third challenge is the hypoxic or anaerobic environment in the host.
Oxygen levels in the intestines are low, and parasites need anaerobic breathing to survive, and once they can't adapt, they will be suffocated alive.
The fourth challenge is the host immune system of hellish difficulty.
As an alien, staying in the host's body will inevitably cause a strong immune response, which can be killed directly or expelled by means of physical warning.
However, some parasites can secrete substances that interfere with the host's immune recognition, disguising themselves as part of the host's body, and the rest is doing whatever they want.
There are many ways to parasite parasitism, and the above is only parasitism in the body.
There is also a method called fecal-oral transmission, which does not mean that humans directly contact feces and then contact the mouth.
It means that after the parasitic feces come into contact with food or water, these contaminated foods and water sources will cause humans to be infected with parasites when they enter the human body.
In the past, living conditions in rural areas were poor, and many people would use manure as fertilizer, causing agricultural products to be contaminated with parasites.
These contaminated foods, if eaten without thorough cleaning, can lead to roundworm infection.
However, now that the conditions are better, this phenomenon rarely occurs in agricultural products, but because the ingredients are not fresh, the probability of our infection with parasites has increased sharply.
<h1 class="pgc-h-arrow-right" data-track="247" >3. Can we eliminate parasites? </h1>
Parasites bring a series of diseases to humans and animals.
What's more, just thinking about a bug burrowing through our stomachs is hard to accept.
But shockingly, some people think that the disappearance of the parasite is a bad thing!
One study showed that only 4% of parasites actually infect humans, and most parasites play an unknown but vital role in ecosystems.
A 2012 study, for example, found that wolves in Yellowstone National Park in the United States were more susceptible to the virus than wild coyotes and foxes in the same area without parasites.
Some people boldly asked for confirmation, believing that parasites can also cure diseases.
In 1989, David Strohn, an epidemiologist from the United Kingdom, first proposed a new medical concept , the "hygiene hypothesis".
David believes that if you are exposed to a variety of viruses and parasites, the human immune system will be exercised, and the probability of getting sick will be reduced.
However, when the epidemic broke out, the British also held the idea of universal immunization, now look at the number of confirmed cases and deaths every day, or listen to it.
David Strohn
So, can the parasite cure the disease?
In the United States, a man named Moises tried such a therapy in order to treat his hair loss.
He drove thousands of kilometers and paid 15,000 yuan just to get a special "drug" – 30 Hookworms of america.
Moises
Did he succeed? Moises said that after inoculating 30 American hookworms, only a little fluffy hair grew.
"If the fluff on the surface of a peach were represented by 0 to 10 for the process from baldness to thickness, I would have been 0.05."
Even more unfortunately, the American hookworm triggered a strong reaction in his body:
In the third week after vaccination, he began to have colic in his abdomen, accompanied by slight dizziness; later the abdominal pain became more and more severe, accompanied by severe diarrhea, and the churning of the intestines made him almost collapse.
In the end, Moises chose to take antiparasitic drugs to say goodbye to these good medicines that he had spent a lot of money on.
However, the proof of parasite cures does have some scientific proof.
Since 2003, 19 phase I/II trials of parasitic diseases have been conducted worldwide.
The scope of treatment includes a variety of allergic and autoimmune diseases, including enteritis, asthma, allergic rhinitis, rheumatoid arthritis, etc.
The parasites selected in these studies were mainly pig whipworm and American hookworm or American plate-mouth nematode.
Unfortunately, in early clinical trials alone, the parasite's therapeutic effect was significantly improved compared to the drug's.
In a series of subsequent controlled trials, there was no strong evidence to confirm the effectiveness of the parasite in curing the disease.
Will people's "fantasies" of parasite cures come to an end? I believe that there will still be some scientists who will tirelessly explore.
As ordinary people, we only need to do: when eating food, we must ensure hygiene, cleanliness, and no infection with parasites.
Xiaobian summarized a few precautions, I hope that everyone will keep these points in mind when eating and drinking:
There is a saying that delicious food is likely to be a "wormhole".
But Xiaobian also wants to say: there are so many delicacies, isn't it a pity to waste food because of choking?
