Solar term health preservation | Heavy snow: a suitable supplement for a quiet winter

Today is the heavy snow festival. There is a saying in Jiangnan that "after the heavy snow winter solstice, the baskets will not leak water." This is to the effect that after the heavy snow festivals, the gaps in the outdoor bamboo baskets are prone to freezing and the water will not leak.

The arrival of the heavy snow festival indicates that the coldest time of winter has officially entered. From the perspective of health preservation, “planting in spring, growing in summer, harvesting in autumn, and storing in winter”, doing a good job of heavy snow health can improve human immunity and resistance, and make good reserves for good physical functions in the coming year.

Nourishment and nourishment

Chinese medicine believes that December has reached a good time for tonic. When it comes to tonics, many people understand that they need to eat valuable supplements with high nutritional value. In fact, tonic is exquisite, and the purpose of health preservation can only be achieved by tonic "depending on the person, time and place".

First of all, it is necessary to maintain a proper regimen, which means that the regimen cannot be adjusted too much, nor too late. You should carefully study your physical condition and choose food tonic and medicine tonic. For example, people with weak physique and poor digestive function should choose "slow tonic", eat more "angelica mutton soup", etc., and eat more vegetables, avoid excessive tonic or emergency tonic. People with good physique should "supplement" and avoid eating greasy products to prevent internal heat from causing diseases. You can use "chicken stew with mushrooms" and "ginkgo stewed black chicken".

In the usual diet, eat more foods high in protein, vitamins, and fiber, and eat less foods high in fat and sugar. You can eat more lamb, beef, celery, white radish, potatoes, Chinese cabbage, spinach, apples, longans, etc. Avoid cold foods such as seafood and cold drinks.

In winter, the human body rarely sweats, so it is recommended to reduce the intake of salt to reduce the burden on the kidneys. It can appropriately increase the bitter food to strengthen the kidneys and nourish the heart. In addition, you can eat more black foods to nourish the kidneys, such as black rice, black dates, black wolfberry, black beans, black fungus, black buckwheat and so on.

The temperature is lower during heavy snow, but the colder the weather, the more water you need to drink. Drinking plenty of water is conducive to the supply of oxygen, breathing smoothly, and maintaining good physical condition. Drink warm and hot water in winter, and drink a glass of plain water after getting up and before going to bed.

Health coup to survive the winter

The climate is cold in winter, and the human body's metabolism is also at a relatively slow level at this time. Therefore, the winter regimen should focus on the word "Tibet".

In order to ensure that the physiological laws of the winter sun qi terminus are not disturbed, it is first required to be quiet and learn to control emotional activities. Don't be overwhelmed with sadness and joy, and recharge your energy.

In terms of daily life, it is advisable to "sleep early and wake up late" during heavy snowfall, go to bed early to nourish yang, and wake up late to consolidate yin. The best time for people to work and rest should be from 10 pm to 6 am the next morning. sleeping time. Dress modestly, too little or too thin can easily catch a cold. When dressing, pay attention to keeping the joints warm. Since the joints are mostly tissues with fewer blood vessels, such as tendons and ligaments, and the outdoor temperature is lower, it is easier to lose temperature, making the joints stiff and poor blood circulation, which can cause pain. Therefore, patients with arthritis must keep warm in the cold winter.

The temperature difference between morning and evening is huge, and the elderly should be cautious in their daily lives and exercise appropriately to enhance their ability to adapt to climate change. Exercise should fully warm up, choose jogging, brisk walking is the most suitable. Do not exercise too early in the morning, avoid strong wind, cold, heavy snow, fog and dew, and not sweat heavily.

Indoors should be ventilated frequently, and doors and windows should be opened during the day to allow air to flow outside. In addition, the room should be moisturized. If the room temperature is too high and the humidity is too low, it will cause physical discomfort and disease. In winter indoor moisturizing, apart from sprinkling some water on the ground every day, or mopping the floor with a wet mop to increase humidity, you can also put a basin of water near the heat dissipation facility to let the water evaporate slowly to keep the indoor air moist.

 Without sex, can't you get cervical cancer? Can I avoid wearing a condom?

It is said that things have two sides, and sex is no exception.

While it brings people enjoyment, it also brings some risks, such as unwanted pregnancy, contracting STDs...

In addition, there is another kind of cancer, as long as you have sex, it will focus on you-cervical cancer.

Cervical cancer is the second largest tumor "killer" of Chinese women. According to statistics, there are about 130,000 new cases each year and 30,000 deaths due to it.

Human papillomavirus (HPV) is the biggest culprit of cervical cancer. 99% of cervical cancers are related to high-risk HPV persistent infection.

The virus is mainly infected and spread through sexual contact. Both men and women may be infected as long as they have sex.

Therefore, I would like to remind everyone that once you have sex, you must beware of this cancer.

Some people may wonder: If you don't have sex, don't you need to worry about infection?

In the background, some readers also mentioned related issues↓

Although we have done a lot of cervical cancer related science, there are still many people who are as ignorant and doubtful as this reader:

I'm still very young, shouldn't worry about cervical cancer?

As long as you pay attention to hygiene and wear a good cover, you will not get infected, right?

I only have sex with the subject, shouldn't I get HPV?

......

Today I will give you a good science wave~

Without sex, can't you get cervical cancer?

There is a huge family of HPV viruses, and more than 130 types have been isolated.

Different types can cause different diseases, such as common warts, flat warts, and condyloma acuminata, including vulvar cancer, penile cancer, anal cancer, oral cancer and so on.

Among them, HPV16 and HPV18 are two viruses that cause 84.5% of cervical cancers.

The main route of transmission is sexual contact. According to statistics, 70% to 80% of women will be infected with HPV at least once in their lives.

In addition to sexual life, HPV infection can also be transmitted indirectly, that is, through contact with body fluids containing a certain amount of active virus, such as sharing bathtubs and bath towels with the infected person.

However, this "indirect transmission" has restrictions:

The part you touch is mucous membrane or wound

There must be a virus in the body fluids, it must be alive, and enough

Only when these conditions are met at the same time can they be indirectly infected.

Therefore, if you don't have sex, you may be infected with HPV and cervical cancer, but the probability is extremely low.

Don't worry about cervical cancer when you are young?

When it comes to cervical cancer, many people think that only older people will get it, and young people don't have to worry about it.

If you think the same way, you are wrong.

Although the high incidence of cervical cancer is 40 to 50 years old, there are many young people in their 20s who are diagnosed.

People of this age are more likely to be infected with HPV because of their active sex life.

It's just that because of being young and having strong immunity, it is easy to clear HPV through the immune system.

Those with weaker immunity will develop malignant lesions if they are continuously and repeatedly infected with high-risk HPV.

Therefore, even if you are young, you should not take it lightly, especially those who have sex too early.

Because the younger the first sex, the greater the chance of cervical cancer in the future.

Especially women who have sex for the first time earlier than 16 years old are at high risk of cervical cancer.

Because the cervical tissue cells of underage women have not matured, the immune system is not perfect, the resistance is low, and they are more sensitive to the stimulation of carcinogens.

Don’t worry about cervical cancer if you talk about hygiene and wear condoms?

Although condoms can block the spread of most sexual diseases, they are not 100% safe.

Even if you wear a condom, there is a risk of HPV infection.

Because the HPV virus can survive in any area around the anus and genitals, these areas are not covered by condoms.

During sex, if you touch these parts, you will be easily infected.

However, "hygiene, wearing condoms" are indeed two very important things in sexual life, so they should be taken seriously.

Especially for male compatriots, you must clean the tintin before sex to prevent the foreskin from hiding dirt.

Because smegma may carry the herpes virus, and the cholesterol in the smegma can be transformed into carcinogens through the action of bacteria, leading to men suffering from penile cancer, and the risk of their wives suffering from cervical cancer is also significantly increased.

Only have sex with the subject, will not be infected with HPV?

Some female compatriots believe that only those who have a disorderly private life are susceptible to HPV infection. I only have one sexual partner, so I am safe.

wrong!

Although you only have one sexual partner, can you guarantee that the man is only you?

If the man has multiple sexual partners at the same time, the higher the chance of contracting sexually transmitted diseases, the higher the chance of you being infected.

In addition, if the man’s ex-girlfriend has been infected, you are more likely to be infected.

According to investigations and studies, if the husband’s ex-wife has cervical cancer, the probability of the second wife suffering from cervical cancer is 3.5 to 4 times higher.

All in all, don’t take a chance. If you have the conditions, it is best to get HPV vaccine, which can effectively prevent cervical cancer.

HPV vaccine-the first vaccine to prevent cancer, the sooner the better

Vaccination of HPV vaccine is an effective means to prevent cervical cancer.

You can get HPV vaccination at the community hospital and community health service center in your place of residence. Due to the large vaccine gap, you generally need to make an appointment in advance.

At present, there are 4 types of HPV vaccines on the market worldwide, namely:

The 4-valent and 9-valent vaccines produced by Merck & Co. (trade name: Jiadaxiu);

The bivalent vaccine produced by GlaxoSmithKline in the United Kingdom (trade name: Xiruci);

The domestically produced bivalent vaccine (E. coli) (trade name: Xinkening) that was launched recently.

The approximate difference between these 4 vaccines is shown in the figure below↓

You can decide which one to play according to your age and financial situation.

Generally speaking, the sooner the vaccination is, the better, and 9-14 years old is the best vaccination age.

It is best to take it before having sex, because the HPV vaccine works best for people with asexual life history.

Here are a few HPV vaccination issues that everyone is more concerned about:

1. Can I still fight if I am infected with HPV?

can

Even if you are infected with HPV, the vaccine can prevent uninfected HPV types, so vaccination is still recommended.

2. Can I fight during pregnancy and breastfeeding?

not recommend

It is currently uncertain whether the vaccine will have an adverse effect on the fetus, so women who are breastfeeding and preparing for pregnancy (plan to become pregnant within one year) are not recommended to receive the vaccine.

In case of pregnancy during the vaccination period, it is recommended to suspend the vaccination and wait until the birth is over before continuing.

3. Can you play if you have sex?

can

The HPV vaccine is best for women who have no sex life history, but even if they have sex, it is still recommended to be given, and it can also play a certain preventive effect.

4. After giving birth, is it still necessary to fight?

necessary

 After the superstar's death, the private doctor was convicted of manslaughter: Why did celebrity doctors "overturn the car repeatedly"?

Being a man is difficult, being a woman is even more difficult, being an old woman is even more difficult.

This is a classic line left by Zhao Benshan and Song Dandan in the Spring Festival Gala sketch.

Similar ridicule on doctors does not seem absurd.

Being a doctor is difficult, being a famous doctor is difficult, and being a famous doctor next to a celebrity is not as fame and fortune as imagined.

On November 25, Maradona died at his home in recuperation due to cardiac arrest at the age of 60. Just five days after his death, the residence and office of Maradona's personal doctor were searched by the police.

The police stated that they would conduct related investigations against the doctor on the charge of "manslaughter" to find out whether there was medical negligence and negligence in the course of recovery after Maradona's operation, which led to Marado. Na's death.

In this regard, the doctor cried at the press conference: he has done his best in the treatment process, but Maradona is not an obedient patient.

"The operation was really successful. I advised him to go to the rehabilitation center after leaving the hospital, but he doesn't want to do that! If he doesn't want to, you can't do anything."

Maradona and his personal doctor (Source: YouTube video screenshot)

Currently, the results of the survey have not been announced. But the outside world is still talking about it, because the grievances between celebrities and doctors really have too many lessons.

Distorted medical treatment: from earning one million a year to going to jail

The most famous precedent is the sudden death of a generation of superstar Michael Jackson.

On June 25, 2009, a press announcement stated that pop star Michael Jackson died at the UCLA Medical Center due to a heart attack.

But the coroner said his sudden death was not simple.

The subsequent autopsy report stated that Jackson was in good health, his heart was well structured, and he did not have atherosclerosis. There was no substantial disease in any other organs except for the inflammation in the lungs. It seemed doubtful that he had a heart attack.

The truth comes from toxicological analysis-the singer has an alarming overdose of various anesthetics and tranquilizers in his body.

Soon after, the court announced that Jackson’s death was due to the anesthetic propofol and other sedatives such as lorazepam and midazolam injected by his private doctor. The police defined the case as a homicide and immediately filed a lawsuit against his personal doctor, cardiologist Murray.

Michael Jackson's personal doctor Murray (Source: YouTube video screenshot)

According to Morrie's confession and the police's recovery on the day of the incident, it is certain that Michael Jackson's personal doctor did have long-term illegal injections of anesthetics and tranquilizers for him:

Due to many factors such as stress, Jackson's sleep quality is extremely low. He has taken sedative and analgesic drugs for a long time to seek sleep effect, which has resulted in severe drug dependence and tolerance.

On the night of his death, he had insomnia again and sought medicine from a private doctor. Morrie gave Valium tablets, and then injected lorazepam half an hour later, but there was no effect.

According to Morrie's confession, after that, he injected midazolam into the singer at 3, 5, and 7:30 in the morning, but it was still a sleepless night for Jackson.

"He kept begging me to give him propofol injections," Morrie said. In the end, he added 25 mg of propofol to Jackson's drip (the amount is in doubt).

Propofol is also nicknamed "little milk" in the industry (Source: Figure Chong Creative)

This action is extremely dangerous. There are no safety measures and strict monitoring during the injection of propofol: there is no monitoring equipment in his home to monitor the patient's vital signs. Obviously, the cardiologist was not prepared to provide the conditions and measures for oxygen inhalation and emergency resuscitation. He even went to the toilet after giving the medicine.

In less than ten minutes, a generation of music legends stopped breathing and passed away. In 2011, the highly-paid doctor Morrie, who was said to have an annual salary of one million, settled the accusation of "manslaughter" and went to jail.

Celebrities and private doctors have always been uncalculated bad debts. Another music legend "Elvis" died suddenly from a heart attack. The police found 14 different prescription drugs including amphetamine, anesthetics, barbiturates, tranquilizers and sleeping pills in the medical record system of his personal doctor. The prescribed doses have reached the level of abuse.

At the same time, the private doctor prescribed a large number of drugs that exceeded the standard for several other celebrities in charge of him. Because there is no evidence of direct death by Elvis, the doctor was not involved in criminal responsibility. However, the Medical Council suspended his medical license for misuse of prescription drugs.

Celebrities hire private doctors with the intention of getting better treatment and health management. However, in practice, it often evolves into the above-mentioned compliance and palliative treatment of well-known patients, which becomes a lose-lose outcome.

Not a stubborn illness, VIP syndrome

For the special phenomenon in the diagnosis and treatment of celebrities, in fact, the academic circles have already put forward the corresponding term, which is called VIP syndrome or VIP syndrome.

In 1964, psychiatrist Walter Weintraub described this abnormal doctor-patient treatment for the first time.

Source: Reference 1

He pointed out that VIP syndrome is not a real disease, but refers to when doctors face VIP figures such as celebrities, rich people, leaders, etc., they may not strictly abide by professional principles or even deviate from standard diagnosis and treatment methods due to various concerns and pressures. , Leading to undesirable consequences.

More than 50 years later, this kind of chronic disease that is not a disease still plagues the doctors.

On October 6, a commentary article published on Medscape pointed out that the treatment of Trump’s new crown is likely to be a bad decision made by the doctors’ group under VIP syndrome.

Facing ordinary patients, doctors know that standard diagnosis and treatment are the best and effective, but when facing VIPs, they may forget these basic principles. For example, because Trump is the president, he uses an antibody cocktail therapy that is not within the scope of standard treatment and can only be used with sympathetic administration.

Trump's physician team (Source: YouTube video screenshot)

Although we all know that Trump will heal soon, not every US president is so lucky under this "special care". In fact, Washington, the first US president, may have been a victim.

After George Washington contracted some kind of bacterial epiglottitis, he underwent the most advanced treatment at the time, bloodletting, four times within 12 hours. According to historical records, he was bled a total of 2.5 liters. In the end, the president passed away on December 14.

VIP syndrome is not only limited to the diagnosis and treatment of celebrity groups, but also makes hospital staff feel uneasy during the VIP hospitalization.

In 2014, the "Boston Globe" reported that a Middle Eastern prince had VIP syndrome at Brigham and Women's Hospital in the United States.

The prince was infected with drug-resistant bacteria. According to the procedures of this top American hospital, he needs to wear protective clothing. But the dignitaries believed that wearing protective clothing was a kind of "dirty" performance, so doctors had to succumb to this unreasonable request. At the same time, the prince’s private team also took over all routine medications in the hospital and even cleaned the IV catheters by themselves.

This hospital is also an affiliated hospital of Harvard (Source: Wikipedia)

Various conflicts between the celebrity's privacy requirements and clinical treatment have made the treatment efficiency very low. The attending doctor said that the prince’s recovery time was much slower than they expected, but fortunately, the "big Buddha" was sent away without any risk in the end.

An anonymous doctor said in an interview: "If something goes wrong, it is definitely not the royal attendant who washes the catheters who will be accountable, but we who can't speak."

In 2017, a survey on the VIP hospitalization environment showed that most of the doctors in the study had been pressured by VIP patients or related personnel to request medically unnecessary examinations or treatments. Even 36% of doctors have been pressured by their own hospitals and forced to comply with the needs of celebrities.

In recent years, a narrative review stated that due to the lack of correct guidelines for VIP syndrome, this phenomenon is no longer a cheerful play on TV and news or anecdotal rumors, and even appears in ordinary people’s daily lives. .

Warning: VIP may be by your side

In this document, the author described a "VIP syndrome" that happened to him.

A colleague from the dermatology department asked the author of the neurology department to see her father. But at the beginning, this colleague listed a long list of "self-considered differences" to the author, and made a diagnosis by himself, and even made two appointments for brain CT, magnetic resonance imaging, coronary CT and otolaryngology.

Fortunately, the author did not let him go. He insisted on listening to the patient's own medical statement, completing an independent diagnosis, and clearly pointed out that the colleague had excessive finger-pointing—if the colleague's wishes, her father would even have to use a pacemaker.

Source: Reference 2

After this incident, the author went to search for other similar cases. He found that for most medical groups, the "special ward" in the hospital is often empty: but patients with special characteristics such as acquaintances, colleagues, friends and family members will also blur the professional boundaries of doctors.

Accidents caused by the deformation of diagnosis and treatment have occurred frequently, and these treatments may have been out of good intentions and favors.

He warned against this: VIP syndrome is not a far-flung term, and it may even have appeared in your working life-but there has been no accident.

At the end of the article, the author gave his own suggestions:

With firm stance and effective communication, no matter how big the opponent is, you can't mess up your position first. If the doctors start to compromise, then this treatment has become a gamble.

 It sells tens of billions every year, and addicts are addicted! The carcinogenic mystery of "Magic Fruit" was revealed for the first time

People who are addicted to betel nut say that after eating betel nut, they are like drinking "Erguotou", their face flushed and the spirit is excited. These states are not psychological effects, but actual alkaloid effects.

Areca nut contains a variety of alkaloids, arecoline and hypo arecoline are the most important ingredients. These substances, like other alkaloids, have an impact on human functions. Among them, arecoline can stimulate the secretion of endogenous ACTH. As a result, the pituitary gland releases more ACTH, which then allows the adrenal glands to produce more ACTH.

It doesn't matter if you have been stunned by this process. Let's put the result of chewing betel nut simple, that is: an excitement process occurs in the human body.

However, betel nut offends "public anger", it is no longer a matter of overnight.

As early as 2003, betel nut was recognized by the International Cancer Research Center as a category 1 carcinogen (representing a clear carcinogenicity to humans), and it is the highest level of carcinogens. In the same category, there are formaldehyde, arsenic, asbestos...

In the list of category 1 carcinogens updated in 2012, the number of carcinogens related to betel nut increased to three.

Betel nut is a complex mixture, and it has not been confirmed which ingredient is carcinogenic. However, a recent academic paper published in "The Lancet-Oncology" revealed the mystery of the "magic fruit" causing cancer.

Betel nut carcinogenic ingredients confirmed for the first time

Including China's Hunan, Yunnan, Hainan and China Taiwan...

According to the assessment of the International Agency for Research on Cancer (IARC) under the World Health Organization, 10%-20% of the world’s population chew betel nut due to refreshing and addiction, mainly in Southeast Asia and South Asia, including China’s Hunan, Yunnan, Hainan and Taiwan. area.

Recently, IARC published a major assessment conclusion on the carcinogenicity of arecoline, the main active ingredient of betel nut, in The Lancet-Oncology. Based on strong mechanism research evidence, arecoline is classified as a category 2B carcinogen-possibly carcinogenic to humans (animal test evidence or limited human carcinogenic evidence).

IARC pointed out that although betel nut has been classified by IARC as a category 1 carcinogen (it is determined to cause cancer in humans), the exact carcinogenic component has not been confirmed. This is the first time that the IARC working group has evaluated arecoline. It is very important and has promoted people's understanding of how areca nut is carcinogenic.

Source: The Lancet Oncology

It is confirmed that betel nut is carcinogenic, why choose arecoline for evaluation?

Arecoline is the main active ingredient of betel nut, which is easily absorbed and can be detected in saliva, blood, urine, hair and breast milk of betel nut eaters. In addition, arecoline is directly used in some traditional medicines.

In terms of compositional properties, arecoline is also an alkaloid like nicotine, and it also acts on nicotinic acetylcholine receptors. At the same time, arecoline is also responsible for other receptors (including muscarinic acetylcholine receptors). Partial agonist.

The reaction of arecoline with sodium nitrite can also form N-nitrosamines, which is also a type of carcinogen and has also been found in the saliva of people who chew betel nuts.

Assess evidence of carcinogenicity of arecoline

The IARC working group evaluated the research evidence on the mechanism of betel nut from academic institutions around the world, including Southeast Asia where betel nut chewing is very common.

1. There is strong evidence that arecoline has a variety of key carcinogenic properties. These evidences come from studies conducted in human primary cells and under various experimental conditions.

Arecoline is electrophilic.

It is genetically toxic. It can induce DNA strand breaks, formation of micronuclei (abnormal structure, a phenomenon of chromosome aberration), chromosome aberrations and sister chromatid exchange in human primary and cultured cells.

Can alter DNA repair or cause genome instability. Arecoline can cause chromosome damage in vitro and in vivo experiments, and can induce gene mutations in mammalian cells in vitro experiments and bacteria. In transgenic mice, arecoline can change the mutation spectrum of mice. In in vitro experiments on human cell lines, arecoline alters DNA repair.

Can cause oxidative stress.

The metabolites of arecoline arecaidine (arecaidine) and arecoline-N-oxide are also genetically toxic.

2. In laboratory animals, limited evidence shows that arecoline is carcinogenic. In two mouse feeding studies, arecoline increased the overall tumor incidence. In multiple carcinogenic studies, arecoline induced malignant esophageal tumors in mice and benign esophageal and tongue tumors in rats.

3. In humans, there is still a lack of sufficient evidence on the carcinogenicity of arecoline.

Based on the above-mentioned main evidence, the IARC expert group designated arecoline as a category 2B carcinogen.

In recent years, the close relationship between betel nut and oral cancer has also received attention for many times. The IARC update of the carcinogenic information of the specific ingredients of betel nut undoubtedly emphasizes the health hazards of betel nut again.

Betel nut has been favored in ancient China

Two Persian handmade Hetian jade jars used to hold betel nuts are Qianlong's lifelong love...

The so-called near the water to the terrace, the Chinese people have a long history of chewing betel nuts.

There is such a record in Yang Fu's "Foreign Objects" in the Eastern Han Dynasty, "Betel nut, like bamboo shoots and bamboo shoots, is hard and hard, with stems straight up, without branches and leaves, and its shape is like pillars... The ears are fruitless without flowers, and are as big as peaches and plums... Take the vines and ancient beech ashes to eat together, lower the breath and eat, and eliminate the insects and grains." At present, this is the earliest record of betel nuts.

Several messages are revealed in this record. First, the appearance of betel nut is similar to that of bamboo poles. The "one mind" grows upwards and leaves on the top of the head. Needless to say, this is actually a major feature of palm plants, whether it is king palm, coconut, or Iraqi dates (dates).

In the above description, another important point is that eating betel nut has special effects, including digestion and deworming. It can be seen that the betel nut was still a medicine at this time, and it was chewed for health. Before the Song Dynasty, medicine has always been the main identity of betel nut.

In Tao Hongjing's "Famous Doctors" in the Jin Dynasty, Liu Xun's "Ling Biao Lu Yi" in the Tang Dynasty, and Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty, there are descriptions of the medicinal value of betel nut. For a long time, people It is even believed that this kind of fruit can get rid of the miasma in southern China, so it is listed as the four major southern medicines along with "Yizhiren, Amomum villosum, and Morinda officinalis". This is enough to explain the status of betel nut in medicine.

The medicinal value of betel nut has been prominent since the Qin and Han Dynasties. According to the records of the "Historical Records" and "Sanfu Huangtu", when Emperor Wu of the Han Dynasty led troops out of South Vietnam, he used betel nuts to resolve the miasma in the army. After the victory of the war, he built the Fuli Palace in Xi'an and built it inside. A large number of southern trees have been planted, including betel nut; in the Tang Dynasty's "Medicinal Herbal Medicine", it is stated that "betel nut is sweet in taste and cold in nature.

After the Song Dynasty, the use of betel nuts began to change. They are not just simple medicines, but more often they play the role of hobbies. Everyone came to chew betel nuts for pleasure, especially in the Lingnan areas such as Hainan and Guangdong, and this habit has continued, and once became a leisure way for princes and nobles. It wasn't until opium and tobacco were introduced into our country that betel nut slowly walked off the altar of the king of hobbies.

During the Northern and Southern Dynasties, the Kingdom of Kantoli (present-day Sumatra) paid tribute to betel nuts, and the court gave them to the ministers. The poems of the courtiers' thanks are mostly recorded in the "Liang History".

Li Yu, the post-master of the Southern Tang Dynasty, wrote about his Great Zhou Dynasty, there are words and phrases like "chewing red velvet, laughing to Tanlang", betel nuts, beauties, and lovers are vivid and vivid.

Qianlong is a good betel nut. There are two Persian handmade Hetian jade jars used to hold betel nuts, which is the long-lived Qianlong love. The two things are kept in the Palace Museum in Beijing.

Jiaqing's imperial approval on the zhezi: "I often take betel nut, you can take it at any time", "only betel nut is one item, I often take it, and every time I present it with the tribute, no mistake." Two folds are now stored in China's first historical archive.

How to pretend to vomit blood? Chewing betel nuts!

"Urban psoriasis" spit on the street-betel nut juice is extremely annoying

The betel nut on the market in my country today is mainly produced in Guangdong, Yunnan, Taiwan, Guangxi and Fujian. In other countries, Indonesia, India, Sri Lanka, and the Philippines have the most output.

In Hainan, many public places write unceremoniously-"It is forbidden to chew betel nuts!"

People who arrive in Hainan for the first time will be very surprised. There are often many red blood stains on the streets. People have to wonder, "How come so many people come to the street to vomit blood?" In fact, these red substances are not blood at all. It's the juice vomited by people who chew betel nuts.

Picture: travel-badger

If you simply chew betel nuts, even if you chew them and then crush them, there will be no bright red juice. If red juice really appears at this time, it is probably because the gums and oral mucosa have been punctured. If you want to get red fruit, you must chew betel nut, shell ash (if shell ash is not available, you can also use lime instead), and burberry leaf (a plant of the Piper family with a special aroma).

Spread shell powder or lime on the leaves, wrap betel nut and chew together.

Picture: TIM SANDLE / digitaljournal

With the assistance of the shell powder and the leaves of the betel nut, the betel nut red pigment (a phenolic substance) in the betel nut will change significantly, showing a bleeding-like color. Worse still, this red pigment of betel nut is not easy to be removed, so betel nut juice spit on the street is very annoying. At this point, betel nut is a bit like chewing gum, and accidentally becomes urban psoriasis.

Therefore, it is not surprising that chewing betel nuts is forbidden in public.

The addition of shell ash and tuber leaf makes the appearance of betel nuts diversified.

Betel nut has long been questioned in China

Why do many people still don't know the harm?

Selling tens of billions every year, addicts are addicted

Betel nut is native to Hainan, but it is popular in Hunan.

Public information shows that the total value of the betel nut industry in Hunan Province last year exceeded 30 billion yuan, accounting for 3/4 of the country's total betel nut output value, and it is still growing rapidly. In Hainan, nearly 2.3 million farmers grow betel nut, and betel nut has become an important local economic crop.

It can be said that the betel nut industry has formed a complete industrial chain. In this huge business empire of betel nuts, it is difficult for the public to know about the dangers of betel nuts.

Prior to this, 13 sets of CCTV's "News 30 Minutes" had extensively reported on the strong carcinogenicity of betel nuts. After the show was broadcast, the price of betel nuts in Hainan plummeted and the income of local farmers dropped sharply.

In September of the same year, two sets of CCTV's "Economic Information Network" "refuted the rumors": the claim that "betel nuts cause cancer" had no scientific basis.

Professor Jian Xinchun, president of the Hunan Stomatological Association, is the first dentist in China who discovered that long-term chewing of betel nut can cause oral mucosal lesions. He and his colleagues have long promoted that "betel nuts cause cancer" and were threatened with "800,000 people buying your head."

In response, he said, "I understand it very well, after all, I moved such a big piece of cake."

Capital makes people "silence" and makes people speak out.

There are even many young betel nut brands frequently appearing on local TV’s Lantern Festival and being implanted in popular web dramas.

However, can the betel nut, which seems harmless to humans and animals but contains carcinogens, really be linked to health?

Because of the addictive nature of betel nuts, the United States forbids the transportation of betel nuts between states as early as 1976, and the sale of betel nut products nationwide in Canada and Australia.

Signs of "No Smoking" and "No Betel Nuts"

In India, another big consumer of betel nuts, the government also requires that the outer packaging of betel nuts be added with pictures of oral cancer to serve as a warning.

Betel nut packaging with warning pictures

my country's Xiamen City issued a policy in 1996 to strictly prohibit the production, sale and consumption of betel nuts. This ban has lasted for 24 years. There have been almost no cases of oral cancer caused by long-term chewing of betel nuts in the two local hospitals.

In stark contrast, in April last year, the expert research team counted 45 oral cancer patients in the ward of Xiangya Hospital in Hunan Province, of which 44 had a long-term history of betel nut chewing.

In February 2019, the National Health Commission issued the "Healthy Oral Action Plan (2019-2025)". Article 3 of the "Specific Actions" in the second part of the plan mentioned:

In areas with the habit of chewing betel nuts, focusing on the hazards of long-term chewing betel nuts to oral health, targeted publicity and education and oral health inspections are carried out to promote early diagnosis and treatment of diseases such as periodontal and oral mucosal diseases.

If you are curious and want to try fresh, in view of the dangers of betel nut, it is recommended not to touch it.

If someone around you is addicted to betel nut chewing, please let him see this article.

 It is the first place in the ranking of liver-damaging fruits! It’s the season now, don’t want to take a bite of bad liver

When it comes to fruit, many people’s first reactions are: natural, healthy, nutritious...

Indeed, fruits are one of the few foods that are both delicious and nutritious: sweet and sour, and rich in nutrients such as vitamins, dietary fiber and minerals.

However, some fruits are not as healthy as we think, and some ways of eating are even more fatal.

Just say that the following fruits are not very friendly to the liver. People with poor liver should pay special attention to keeping their mouths shut.

On the liver-injury fruit rankings, the number one is actually...

1. Grapefruit

How did the delicious grapefruit become a "liver injury fruit"?

Grapefruit itself is a good fruit, but after encountering certain drugs, it will change from "angel" to "devil"!

It is the compound "furocoumarin" contained in grapefruit that is causing trouble, which inhibits the activity of liver drug enzymes in the human body and affects the liver's detoxification function.

As a result, the human body cannot metabolize and decompose certain drugs in time, resulting in an increase in the concentration of the drug in the blood, which not only enhances the pharmacological effects, but may also enhance adverse reactions.

Last year, Mr. Liu from Wuhan had muscle dissolution because he ate grapefruit after taking the lipid-lowering drug atorvastatin▽

In addition, after taking antihypertensive drugs and eating grapefruit, the effects of antihypertensive drugs will be superimposed several times to several tens of times, and even serious side effects such as sudden drop in blood pressure will occur.

Drugs such as antihypertensive drugs and lipid-lowering drugs are too common. If you don't know the contraindications, you will be particularly vulnerable.

Precisely because these medicines are common, in addition to reminding people who are taking medicine, we must also look after children!

Not long ago, there was a tragedy in Guangdong where a girl accidentally took antihypertensive drugs and died ▽

Healthy eating grapefruit tips▽

When taking these drugs, do not eat grapefruit: some antihypertensive drugs (such as nifedipine), some hypolipidemic drugs (such as statins), cisapride commonly used in the digestive system, and antipyretic and analgesic drugs containing caffeine.

After taking the above drugs, eat grapefruit at least 3 days later: Generally, after eating grapefruit for 3 days, the effect of furocoumarin on the human body gradually disappears.

Beware of the "close relatives" of grapefruit: such as grapefruit, oranges, tangerines, and lemons. Take this medicine with caution.

2. Avocado

In recent years, avocado is particularly popular in the weight-loss industry, and it is indispensable in various fat-reducing meals.

However, let me tell everyone a heartbreaking fact: avocado is fatter than meat!

Not much to say, look at the data: the fat content of avocado is about 15%, which is much higher than the average lean meat and fish (fat content is about 3% to 5%).

It is not an exaggeration to say that by eating a larger avocado, your daily fat intake will exceed the limit.

In 200 grams of avocado pulp, there are about 30 grams of fat, and we cannot eat more than 25 to 30 grams of oil a day.

As we all know, the liver is afraid of being "fat". If you eat too much high-fat food, fat will accumulate in the liver, forming fatty liver and eventually causing liver damage.

Therefore, if you don't want to "fat" the liver, it is better to eat less avocados, just eat 1/4 avocados each time.

3. Durian

Durian is on the list because of its high sugar content: in 100 grams of pulp, the sugar content is as high as 27 grams.

And sugar is also a veritable liver "killer"——

Sugar is metabolized in the liver, and the liver converts sugar into fat, which increases triglycerides and causes insulin resistance, leading to metabolic syndrome and possibly damaging the liver.

Moreover, the fat content of durian is not low (more than 5%), although it is inferior to avocado, but it can also be comparable to ordinary meat.

Recommendations: Healthy people should not consume more than 2 petals of durian a day (the edible portion does not exceed 100g); patients with obesity, fatty liver, diabetes, and hyperlipidemia should try not to eat it. If you are really greedy, the daily amount should be controlled within 1 small.

After reading this list of liver-damaging fruits, is it quite unexpected?

Although we have been eating fruit for many years, we don’t understand fruit as much as we thought~

Next, please accept the challenge and take a look at the "6 Fruit Cold Knowledge" below, is it cold enough for you——

6 fruit cold knowledge, which one are you so cold?

1. These fruits make your skin darker as you eat

Mangoes, pineapples, lemons, citrus, figs, etc. are all "photosensitive fruits".

This kind of fruit contains a kind of photosensitive substance, after eating, the photosensitive substance will enter the skin.

If exposed to the sun at this time, the skin will absorb more ultraviolet rays, which will be easy to be tanned, sunburned, and even photosensitive dermatitis.

Recommendation: After eating these fruits, do not expose them to the sun for a long time; and patients with skin diseases such as dermatitis, eczema, solar dermatitis, etc., it is best not to eat these fruits before going out.

2. Eating these 3 kinds of fruits will be detected as "drunk driving"

After eating lychee, durian, and jackfruit, take an alcohol blow test immediately, the alcohol content will exceed the standard!

Because these three kinds of fruits have high sugar content, the sugar will be fermented and decomposed after a long time to produce alcohol.

Generally speaking, 5 or 6 lychees may be "drunk driving", while durian and jackfruit have higher sugar content and are more likely to be recruited~

Recommendation: In order to avoid unnecessary misunderstandings, it is best not to eat these fruits when driving, or wait 10 minutes after eating before driving.

3. The hoarfrost on the grapes is harmless to the human body

The hoar frost on the glucose is actually the wax secreted by the grape itself, which will not harm human health.

Moreover, glucose with hoarfrost is often fresher~

4. The pomegranate seeds eaten in the belly will remain intact...

Since pomegranate seeds are harder and difficult to digest in the stomach, they will often see you tomorrow in the toilet after eating them.

5. Apples can float in water

When you "plop" the apple in the water, the apple will slowly float up~

This is because the apple fruit contains 25% air.

6. You are eating pineapple, pineapple is also eating you

Have you noticed that when you eat pineapple, your mouth will become astringent, and you may even feel that your tongue and mouth are "bitten", itching and numb~

This is actually the bromelain in the pineapple is "making a ghost"!

This enzyme has the ability to "break down protein", which is equivalent to the ability to "eat meat".

So, you are eating pineapple, and pineapple is also eating you!

Suggestion: Let the pineapple soak in a salt water bath! Salt water can inhibit the activity of proteases and reduce irritation to the tongue and mouth.

 A Singaporean newborn has a new crown antibody, and the mother was infected with the new crown during pregnancy

China-Japan Friendship Hospital Cao Bin: New coronary pneumonia may cause long-term effects on patients

Recently, the 2020 Lancet-Chinese Academy of Medical Sciences Conference on Medicine and Health was held online. Cao Bin delivered a speech at the meeting, calling on the medical community to pay attention to the long-term follow-up study of patients with new coronary pneumonia.

Cao Bin and others conducted a follow-up study on the long-term consequences of patients with new coronary pneumonia after discharge at Wuhan Jinyintan Hospital. The follow-up results showed that more than 70% of discharged patients reported at least one symptom including fatigue, muscle weakness, sleep disturbance, joint pain, lack of appetite, anxiety, depression, and difficulty walking. The first three are the most common; there are 29 % Of patients cannot successfully complete the 6-minute walking test; more than 20% of patients report psychological complications. By observing the patient’s lung CT images, Cao Bin’s team found that six months after the onset of new coronary pneumonia symptoms, half of the patients still had at least one CT abnormality, but most of the patients had reduced CT abnormalities.

In addition, Cao Bin’s team study also investigated the time changes in the seropositivity and titer of the new coronavirus antibody: Compared with the acute phase, the seropositivity and titer of neutralizing antibodies were significantly reduced; N, RBD and S during follow-up The seroprevalence rate of -lgG still exceeds 90%, but the seroprevalence rate and titer of N, RBD and S-lgM and N, RBD and S-lgA are significantly reduced. That is, the seropositivity rate of IgG antibodies that specifically bind to the three proteins is still over 90%, but the seropositivity rate and titer of IgM and IgA are significantly reduced. Therefore, Cao Bin believes that patients whose antibody levels drop faster may be at greater risk of re-infection. These patients should become at-risk groups. When observing vaccine effectiveness, they should be observed as risk groups.

At present, the study has not been officially published. Cao Bin said that a one-year follow-up study will be planned for the recovery of new crown patients. (Source: Caixin)

A Singaporean newborn has a new crown antibody, and the mother was infected with the new crown during pregnancy

In March this year, a pregnant woman in Singapore was diagnosed with new coronary pneumonia; in early November, she gave birth to a baby boy. As a result, the newborn was not infected with the new crown virus, but also had antibodies. This woman is one of the few people in Singapore who contracted the new crown during pregnancy and gave birth. Whether the antibodies in the baby's body come from the mother or the baby's own production remains to be studied.

A paper published in October by the journal Emerging Infectious Diseases showed that the levels of IgG antibodies in the bodies of 11 pregnant women with COVID-19 in Wuhan were detectable at birth, and the levels of IgM antibodies were detectable in 5 of the babies.

It is understood that IgM is the initial antibody that responds to infection. However, due to the large size of the antibody, it is usually not transferred from the mother to the fetus through the placenta. Smaller IgG antibodies can be transferred from mother to fetus through the placenta. The duration of immunity of maternal IgG antibodies is not known.

Associate Professor Tan Hak Koon, chair of the Department of Obstetrics and Gynecology of KK Women's and Children's Hospital, said that it is still unclear whether the antibodies in the newborn baby can prevent the new crown infection to a certain extent, let alone the duration of this protection.

115 new cases were confirmed in a single day in Hong Kong, and kindergartens, primary and secondary schools suspended face-to-face teaching

On November 29, the Health Protection Center of the Department of Health of the Hong Kong Special Administrative Region Government announced that as of 0:00 that day, there were 115 new confirmed cases of new coronary pneumonia in Hong Kong. Since the beginning of August, the number of confirmed infections once again exceeded 100 in a single day. A total of 6,238 confirmed cases of new coronary pneumonia have been reported in Hong Kong.

The SAR government announced that from December 2nd, face-to-face classes and school activities in all kindergartens, primary and secondary schools in Hong Kong will be suspended until the beginning of the school’s Christmas holiday, and tutorial schools will suspend face-to-face classes for two weeks.

According to Zhang Zhujun, director of the Infectious Diseases Division of the Center for Health Protection, 109 of the newly confirmed cases are local cases, of which 24 cases are of unknown origin, and most of the rest are related to the previous dancing infection group. In addition, there are 6 imported cases. (Source: Xinhua News Agency)

UNAIDS releases 2020 World AIDS Day report

On November 30, the UNAIDS released the 2020 World AIDS Day report "People-centered, we will eventually defeat the epidemic", calling on all countries to increase investment, support the response to various pandemics, and develop a set of bold, Ambitious and feasible new stage HIV prevention and control goals.

The report shows that before the outbreak of the new crown epidemic, the global response to AIDS has deviated from the established track, and the rapid spread of the new crown virus has made the situation worse.

According to the model of the long-term impact of the new crown epidemic on AIDS prevention and control, the new crown pandemic will result in an additional 123,000 to 293,000 new HIV infection cases and 69,000 to 148,000 AIDS-related deaths globally between 2020 and 2022.

In 2025, UNAIDS’ new HIV prevention and control goals will be “people-oriented”, focusing on the highest-risk groups and marginalized groups, including young women and girls, adolescents, sex workers, transgender people, injecting drug users and men. Homosexuality and other men who have sex with men.

The focus of the 2025 target includes providing HIV services to more than 95% of the sub-populations of HIV-infected and high-risk groups; reducing countries with punitive laws and policies to less than 10%; and reducing stigmatization and Reduce the discrimination of HIV-infected or affected people to less than 10%; reduce the number of people who suffer from gender inequality and violence to less than 10%.

Mobile phone explosion caused serious injury to husband and wife and death of both children! Don’t make 4 mistakes with your mobile phone. Everyone must know the 4 signals before the explosion

There was a street interview and asked: Would you like to give you 10,000 yuan and let you not use mobile phones for a month?

A passerby replied: You can have no money or a wife, but you must have a mobile phone!

To be honest, the editor's answer is the same. But a piece of news that I recently saw made the editor, who was inseparable, very scared...

The mobile phone exploded, causing serious injuries to parents and the death of a pair of children

Like many young people nowadays, a young couple in Changde, Hunan is used to charging their mobile phones in the bed before going to bed at night.

I thought that using the time to recharge while sleeping would save you the trouble of bringing a power bank the next day. But the accident happened like this.

Video source/network

In the early morning, the mobile phone suddenly exploded, igniting flammable materials such as bed sheets and bedding. The sleeping family had no time to react, and was ruthlessly swallowed by the fire in just a few minutes!

That night, a family of four was rushed to the hospital. Unfortunately, the 3-year-old son and the 1-year-old daughter who had just turned 1 year old died of organ failure due to excessive injuries!

Although my mother was not life-threatening, her head and upper limbs were also severely burned; my father suffered burns to his hands.

Image source/network

A pair of children who were originally lively and healthy were separated by yin and yang overnight, which was really devastating.

It is hard to imagine how this couple can get out of the shadow of the accident.

In fact, accidents involving mobile phone explosions and spontaneous combustion have occurred every now and then.

Image source/network

After reading it, I feel that what I am holding is not a mobile phone, but whether there is a time bomb!

So, what caused the explosion of the mobile phone?

The mobile phone exploded and spontaneously ignited, mostly because...

1. There is a problem with the battery itself

If the battery is defective, it may explode even when it is not charged.

Therefore, everyone must buy mobile phones and replace original batteries through formal channels, and don't buy some low-quality products for cheap.

2. The phone is placed in a place where the temperature is too high

The battery is not resistant to high temperatures. If the phone is placed next to high temperature or flammable materials, it may cause an explosion.

Earlier, when Ms. Jiang was driving, her mobile phone suddenly exploded and caught fire. It was later proved that the high temperature in the car caused the spontaneous combustion of the mobile phone battery.

Video source/network

3. Mixed use of chargers and charging cables

Many mobile phone explosions and electric shocks are caused by the use of non-original chargers.

The battery capacity of different brands of mobile phones is different, and the charging power of different chargers is also different, so it is most suitable to match each other.

If you use a high-power charger to charge a small-capacity mobile phone battery, there is a certain safety risk.

Therefore, it is best to use original accessories when charging. Don't mix it with others, and don't buy cheap chargers and charging cables from street vendors. This is not saving money, but gambling!

There are 4 signs on the phone, beware of the explosion, so stop playing!

1. The phone is too hot

Charging for a long time, making a phone call, or playing with the phone while charging, etc., will cause the phone to overheat. Generally speaking, it is a normal phenomenon. Just take a while to cool down.

However, if the phone suddenly becomes hot during normal use, the operation should be stopped immediately.

2. Not charging

If the phone cannot be charged, either the charger has a problem or the battery has a problem.

If the cause of the charger is ruled out, it is likely that the battery is broken and must be repaired in time.

3. Frequent automatic restart

Frequent restarting will keep the phone running at a high speed, and it may explode when it heats up to a certain level.

So, don't use it anymore in this situation, and send it for maintenance.

4. The battery is obviously aging

For example, the surface of the battery bulges, liquid is flowing out, etc., indicating that the battery has a problem and must not be used again.

Don't make 4 mistakes when playing mobile phones, all of them are terrible!

1. Charge your phone on the bedside

The charging process is the time when lithium batteries are most likely to have safety accidents. Many battery explosions and spontaneous combustion accidents occur at this time.

Therefore, when you go to bed at night, it is best not to charge your phone by the bedside. Otherwise, once an accident occurs, it is difficult for people to respond in time.

Moreover, when the bedding encounters an open flame, it is easy to be ignited and cause a fire. The accident mentioned at the beginning of the article is such a situation.

2. Play while charging

In most cases, charging while playing with your phone will not cause safety accidents such as explosions.

But not afraid of ten thousand, just in case. After all, playing with the phone while charging may indirectly lead to some potential dangers, causing the phone to explode or ignite spontaneously.

For example, charging a mobile phone while playing will generate more heat than when it is simply charging. Insufficient heat dissipation for a long time may result in battery and circuit aging.

If you still use non-original batteries, charging cables, and chargers, the risk is even greater.

Moreover, there is a risk of electric shock when playing with a mobile phone while charging.

On August 16, 2019, when Xiao Liu, a 13-year-old boy in Nanchang, Jiangxi, was charging and playing with his mobile phone in a fast food restaurant, he suddenly stiffened and collapsed on his seat. Two hours after being sent to the doctor, Xiao Liu still died.

Image source/network

Although explosions and electric shocks are small probability events, we cannot bet on fate. If something happens, no one can bear the consequences!

Therefore, try to play as little as possible while the phone is charging. If you must play, you have to use original accessories.

Also, once the phone gets hot, stop and let it dissipate heat.

3. Walk and play

Not long ago, in Anhui Hefei subway station, a woman was playing with a mobile phone while walking down the stairs. She stepped on the empty foot and fell to the ground with her head down and was seriously injured.

Image source/network

Don't play with your mobile phone while walking, everyone knows the truth, but in reality, many people still can't control themselves.

Image source/network

After reading these, would you still dare to walk and play with your phone?

4. Use low-quality power banks

Unqualified power banks are more prone to short circuits, especially when they are hit by heavy objects, they can burn the phone, or cause explosions and fires.

Before, there was a fire incident in the Lijiao station of Guangzhou Metro Line 3 where a passenger power bank caught fire.

Video source/network

Therefore, don't be greedy to buy low-quality power banks at a small price, and be sure to choose products with safety certification (usually you can find the logo on the shell). 

 The fruit that can reduce the incidence of cancer is the best to eat this season. The key is to eat it!

There is a kind of fruit, it is good in quality and cheap, you can eat it all year round, and you can buy it all over the world. Recently, it is the best season (November to December).

There is a kind of fruit, which is a healthy food recommended by doctors and nutritionists.

Even a number of epidemiological studies, eat it every day:

Can reduce the risk of lung cancer by 11%;

Reduce the risk of colon cancer by 34%;

Reduce the risk of breast cancer by 21%;

Reduce the risk of cancer of the digestive tract by 50%...

There is a kind of fruit that is good for our brain, lungs, skin, bones, eyes, heart, teeth, intestines, kidneys, bladder, liver, etc. It is a well-deserved "general practitioner" in the fruit industry!

Did you guess it?

It's apple

Apple: Nutritional value is almost perfect

Why is Apple a "general practitioner"

"An apple a day keeps the doctor away." Is this saying really scientific?

The answer is: really!

Anti-cancer research findings

Regularly eating apples is good for reducing the risk of lung cancer, colon cancer, oral cancer, throat cancer, esophageal cancer, liver cancer and other cancers, and you only need to eat a big apple every day to get this benefit.

Cardiovascular research findings

Eating apples for a long time can help balance cholesterol levels and reduce the risk of coronary heart disease.

An Oxford University study found that prescribing an "Apple Prescription" to people over the age of 50 would prevent or delay about 8,500 British people from having a heart attack or stroke each year.

Another study also showed that people who eat apples are 40% less likely to have a myocardial infarction than those who do not.

Osteoporosis research findings

Compared with eating sugar water with the same sweetness, eating 311 grams of apples or canned apples per day can effectively reduce the acidity of urine, reduce the loss of urine calcium, and prevent osteoporosis. The phlorizin in apple skin is particularly helpful for preventing osteoporosis in ovariectomized animals (menopausal aging model).

Diabetes research found

Regularly eating apples will not only not increase the risk of diabetes, but slightly decrease it. At the same time, apple is a kind of low glycemic index fruit, which raises blood sugar very slowly. It is also suitable for diabetics.

Dental research findings

Chewing apples helps to clean your mouth and protect your teeth. Although it contains sugar, it does not increase the risk of dental caries.

Respiratory study found

Eating apples can improve bronchial function and help prevent chronic obstructive pulmonary disease.

Intestinal flora study found

High-fat, high-sugar and obese experimental animal mice ate 0.2% of the dietary apple proanthocyanidin extract for 20 weeks, reduced obesity (apples are also good for weight loss), decreased insulin resistance, reduced inflammation, and healthy intestinal flora The direction is back.

Obstetrics and Gynecology research findings

Pregnant mothers eating more than 4 apples a week can reduce the risk of breathing difficulties and asthma in future babies by 50%.

Apple, do you really know how to eat it?

Apples have good nutrition, but there are still many disputes on the choice of varieties and eating methods, such as:

Controversy 1: Should I peel it?

Refer to the speech by Professor Zhang Wen of the College of Agriculture and Biotechnology of China Agricultural University in the media:

The nutrient content in apple peel is very rich, but people are worried about pesticide residues.

In fact, the currently formally grown apples basically meet the pollution-free standards, and the apples have been bagged "when they were young," and they are basically inaccessible to pesticides. They can be washed with water and eaten directly.

Generally speaking, those with neat fruit shape, smooth surface, lighter color, and small difference between different fruits are often produced by bagging.

However, Professor Jiang Weiwei from the School of Food Science and Technology of China Agricultural University also suggests that if you buy cheap apples from mobile vendors, or if you have fallen apples mixed with inferior apple products, it is safer to eat them after peeling them.

Controversy 2: Are golden apples in the morning and rotten apples in the evening real?

Yu Weihua, a national second-level public nutritionist, said that no matter when you eat apples, the nutritional value does not change. The food intake is reasonable and a balanced diet is the most important thing.

However, people with gastrointestinal discomfort are not recommended to eat apples on an empty stomach.

Controversy 3: Which apple is the most nutritious?

From Red Fuji, Huang Marshal, Guoguang to Granny Smith, etc., although the appearance of these apples is very different, but the content of sugar and organic acid is different, and the nutrition is almost the same.

In terms of taste and taste, you can choose from Golden Delicious soft, Fuji hard, granny acid and Guoguang sweet.

Controversy 4: Do I have to eat one a day?

Not necessarily.

Jinru Fu, chairman of the Tianjin Nutrition Society, said that the "Dietary Guidelines for Chinese Residents" recommends eating 200-400 grams of fruit per day, which is basically enough for a large Fuji apple.

However, Fu Jinru also pointed out that there is no need to stick to the "one apple a day", just 3 to 4 a week, and you can eat other seasonal fruits.

In addition, due to the hard texture of apples, it is best to chew slowly when eating to avoid gorging, so as not to damage the intestines and stomach.

The best time to eat apples is between meals. Pay Jinru said that as a snack, apples can provide the water and nutrients needed by the body and brain, and can also bring a feeling of fullness and reduce the amount of food for dinner.

Before eating,

Let the effects of apples be maximized!

Baked apple

Double the effect of lowering lipid and cholesterol

The three ingredients contained in apples amazed doctors.

First, pectin. This soluble fiber can help lower blood pressure and blood sugar, it can also help lower the level of "bad cholesterol" in the body, and like other fiber, it helps the digestive system maintain a healthy state.

Second, boron. The nutrients contained in this apple can strengthen bones and brain.

Third, quercetin. A flavonoid contained in apples. This nutrient can reduce the risk of various cancers including lung cancer and breast cancer. It can also reduce the damage of free radicals to the body and delay the occurrence of various degenerative diseases including Alzheimer's. .

If the apple is baked in a microwave oven, the molecular weight of pectin will be reduced, and its activity will be 9 times higher than that of raw apples. The effect of pectin in inhibiting cholesterol and neutral fat and the effect of inhibiting the rise of blood sugar will increase.

Baked apples can lower cholesterol, prevent high blood pressure, diabetes, asthma, constipation, edema, and eliminate wrinkles.

Baked apple

Method: Take 1 apple, wash and cut the skin into 4 pieces, remove the core. Place the apples on a plate and heat them in the microwave for 5 minutes. Eat them with a meal or by themselves. Eat one apple a day.

Tips: The baked apple is fragrant and soft, very delicious, but remember, you can only eat one. It's best to put it for dinner, eat a baked apple before the meal, and then eat some vegetables and lean meat.

Cook and eat

Double the antioxidant effect

Of course, the method of heating apples is not only baking. If you don’t have a microwave oven at home, you can also cook apples. This is the simplest and most suitable for middle-aged and elderly friends.

Studies have shown that when apples are heated, the content of polyphenols natural antioxidants will increase significantly, which helps to reduce blood lipids, remove excess free radicals in the body, and delay aging.

Apple contains special substances such as tannic acid, pectin, and dietary fiber, so it has the dual effects of antidiarrheal and laxative.

●Unheated pectin can soften stools and play a laxative effect together with dietary fiber. The cooked pectin not only absorbs bacteria and toxins, but also has astringent and antidiarrheal effects.

Therefore, it is recommended that patients with constipation eat more fresh apples (1 apple on an empty stomach every morning and evening), and patients with diarrhea may wish to cook apples to eat.

●In addition, the iodine in ripe apples is 8 times that of bananas and 13 times that of oranges. Therefore, ripe apples are also one of the best fruits for preventing and treating big neck disease.

●Ripe apples can also prevent internal heat such as heat sores on lips, gum inflammation, and cracked tongue.

Boiled apple

Ingredients: apples, raisins, water

practice:

1. Cut the apple with skin into six to eight pieces, put it into a pot of cold water and cook;

2. After the water is boiled, take out the apple and eat it with the skin;

3. Add a few raisins after the apples are ripe.

Apples are best eaten with the skin when they are cooked. This is because foreign studies have shown that apple peel has stronger antioxidant properties than pulp, and can better assist in reducing blood lipids.

Apple with pork

Reduce blood pressure and blood lipids

Many people are accustomed to putting some hawthorn in stew, which can reduce blood lipids, but because hawthorn stimulates gastric acid secretion, it is not suitable for patients with gastric ulcers. You might as well put some apples in the stew, which can increase nutrition and inhibit the rise of cholesterol, and even people with a bad stomach can eat with confidence.

why?

●First, apples can inhibit the increase in cholesterol. Because apples are rich in malic acid, dietary fiber, pectin and other substances, these substances promote the conversion of blood cholesterol to bile acid, which has the effect of lowering cholesterol, so that people can avoid absorbing excessive cholesterol when eating meat.

●Secondly, the fruity aroma of apple can eliminate the peculiar smell of pork.

● Third, Apple can lower blood pressure and protect cardiovascular and cerebrovascular health.

Apples are rich in potassium salts.

A total of 30,000 subjects were recruited for this trial. The main efficacy analysis of 196 symptomatic COVID-19 cases showed that the vaccine's effective rate of protecting symptomatic COVID-19 was 94.1%. All 30 severe COVID-19 cases appeared in the control group, which means that this vaccine is 100% effective in preventing severe COVID-19 cases.

In terms of age, race and ethnicity, and gender demographics, the effects are consistent. The 196 COVID-19 cases included 33 elderly (65 years and older) and 42 participants from different ethnic groups (including 29 Hispanic or Latino, 6 Black or African American, and 4 Asian American And 3 multi-ethnic participants).

The safety of the phase 3 study of mRNA-1273 is under continuous review, and no new serious safety issues have been found. According to previous analysis, the most common adverse reactions include pain at the injection site, fatigue, myalgia, arthralgia, headache, and erythema/redness at the injection site. After the second administration, the frequency and severity of spontaneous adverse reactions in the mRNA-1273 group increased. (Source: Moderna)

The American Red Cross collected 7389 routine blood donations archived samples collected from December 13 to January 2019 in 9 states (California, Connecticut, Iowa, Massachusetts, Michigan, Oregon) , Rhode Island, Washington and Wisconsin) residents were tested for anti-CDS-CoV-2 antibodies. It was found that 106 blood samples contained antibodies to the new coronavirus.

These findings indicate that SARS-CoV-2 may have been introduced into the United States before January 19, 2020, earlier than the first reported case.

The author said that as the world continues to fight the new crown, this study will help expand health officials' understanding of the epidemic.
