If you don t finish drinking too much tea, will drinking overnight tea cause cancer?

Strictly speaking, drinking overnight tea will not cause cancerSo the reason why drinking overnight tea will cause cancer, this statement is because overnight tea will be detected, there are trace amounts of ammonium nitrite, and nitrite amine is one of the main carcinogenic substances, but we need to note that ammonium nitrite will only cause cancer after reaching a certain dose, and the nitrite amine contained in overnight tea is extremely small, in this case, even if we drink it for a long time, it is difficult for us to develop cancer, for example, many foods in life contain nitrite amines, such as pickled foods, Overnight dishes, specially processed bacon, etc. all contain nitrite amines, but they are also trace elements, so it is too superficial to judge whether we will have cancer based on this indicator alone. But for the sake of health, we still try to stay away from this ammonium nitrite. In fact, the real causes of cancer in life may be the following:

1. Aflatoxin

According to the World Health Organization, aflatoxin is listed as a class of carcinogens recognized by the World Health Organization, this substance only needs one gram to produce 100% of us liver cancer, so we must pay attention to aflatoxin, which generally occurs in some moldy and spoiled foods.

2. Overnight dishes

Although we said above, overnight dishes will contain trace amounts of nitrite, but we need to note that some families often eat overnight dishes, almost every day, so it is more dangerous, because occasionally eating some nitrite may not be harmful to our body, but every day only means that a large amount of nitrite will be ingested.

3. Oil smoke

According to the report released by the World Health Organization, more than half of all lung cancer patients are women, which is a state caused by frequent inhalation of these kitchen fumes.

Overnight tea is not allowed to drink, because overnight tea contains a large number of carcinogens, and if you eat it regularly, it is likely to lead to cancer, so you must contraindicate it.

Overnight tea will definitely cause cancer, because after brewing overnight, the tea has become invalid, and then a special chemical reaction is produced, so in this case do not drink it again.

There is no scientific basis for drinking tea overnight tea will cause cancer, overnight tea refers to tea soaked for more than 12 hours or tea that has been put on hold overnight, but its nutrients and hygiene are reduced.

Drinking too much tea overnight can cause cancer is fake. Because the overnight tea is because of the excessive oxidation of tea polyphenols, which makes the color of the tea darker, he is not toxic***, but because it contains very trace amounts of nitrosamines, although long-term large amounts of ingestion will cause cancer, because the content in the tea is very small, so there is no need to worry.

No. Although overnight tea is left out for a long time, it has a very low nitrite content and is not toxic. Therefore, overnight tea can be drunk, but the color of the tea leaves will become dark and cloudy after being left overnight, and the taste will not be good.

However, tea over 65% can cause cancer, and long-term consumption of hot tea will increase the risk of stomach cancer and esophageal cancer.

It's true, this is because the overnight tea has been left for a long time, so there are many nutrients that have deteriorated, and after drinking it to the body, it will produce a certain amount of *** to the body.

In our country, tea culture has a history of thousands of years, so there are more and more friends, are in love with drinking tea, and tea is not just a drink, it contains rich connotations, but with the more and more abundant tea more and more popular, there are more and more topics about tea and health, a lot of tea can be healthy, a lot of tea can strengthen the body, however, there is a saying that everyone has been holding different suggestions, that is, overnight tea is harmful to health, and overnight tea is an exaggeration of the fact.

1. Usually, overnight tea mainly refers to the tea we brewed the day before yesterday to stay for the next day, in life, there are many friends who believe that the reason why overnight tea can not be drunk is that most of the vitamins have been lost, and the protein, sugar, etc. in the tea soup have become nutrients for bacteria and mold reproduction, and they are easy to deteriorate, so they can not be drunk.

2. Regarding the rumors on Weibo that "after the tea is left overnight, nitrosamines will be produced, and nitrosamines are carcinogens", Tu Youying said: "Even if the overnight tea contains nitrosamines, it is insignificant, compared with the bread, fish products, meat products, pickled vegetables and pickled products we often eat, this amount is very small."

3. Only when it coexists with nitrate and can undergo chemical reactions, secondary amines can form nitrosamines, and when nitrosamines accumulate to a certain amount, they can produce carcinogenic effects; Tea polyphenols and vitamin C ingested from tea can prevent the synthesis of nitrosamines, so drinking overnight tea will not cause cancer.

4. Although most of the vitamins may have been lost due to the long time of overnight tea, overnight tea still has many functions. It can help us fix our teeth and clean our teeth, and after calcifying the fluoride in the tea and the enamel of the teeth, it will enhance the resistance to acidic substances and reduce the occurrence of tooth decay; Fluoride can also eliminate plaque, and it is best to rinse your mouth with tea two or three minutes after eating.

The above is to explain some knowledge for you, you need my support to help you, now there are many people, he often drinks a kind of tea, now due to the different weather and climate, so we should adjust their tea in moderation. Sometimes we can drink some flower tea in the spring.

It is indeed true, because there are a lot of toxic substances in overnight tea, and these toxic substances accumulate in the body all year round, which can lead to cancer.

It's true, drinking too much can indeed lead to problems in the body, overnight tea is not allowed to drink, and drinking too much can indeed induce cancer.

It's fake, drinking too much tea overnight will make the body uncomfortable, but the carcinogenicity is very small, it's just nonsense.

Fake. People should drink tea that has not been brewed for a long time, try to drink overnight tea as much as possible, and it is best not to drink it.

This is true, because after leaving it overnight, there are a lot of toxins in the tea, which cannot be absorbed after entering the human body, and eventually lead to cancer.

It's true. Because overnight tea contains a lot of bacteria and viruses, drinking too much may produce carcinogens.

It is true that tea will produce a lot of harmful toxins after being left overnight, and if you drink it for a long time, it will cause cancer in the body.

Many people are very fond of drinking tea, and we feel happy when we drink tea. But it was found that many people said that drinking too much tea overnight may lead to cancer, so is this really the case? <>

There are many experts who have investigated this problem and found that overnight tea does not actually lead to carcinogenic phenomena, if we do not drink the tea that day, then it is indeed likely to lead to the loss of nutrients in the tea. But when it comes to carcinogenic defense, there is some exaggeration, so we don't have to worry, we just need to drink less overnight tea, overnight tea is not as high as freshly brewed tea, and the nutritional content is so high, but it will not be carcinogenic. In fact, there are too many carcinogenic substances in life, if we don't touch these things for a long time, it will not have a certain impact on our body, and we don't have to worry about it.

Drinking tea has a history of thousands of years in our country, and many people will make their bodies healthier by drinking tea, for example, tea contains tea polyphenols, tea polysaccharides and caffeine, which can effectively help us improve our spirits. And it also has the effect of reducing the fire of the eyes, in addition, like some people who drink tea for a long time, they will feel that their hearts are quiet. And proper intake of tea polyphenols can also effectively help us block some bacteria and make our body healthier.

But we need to pay attention to the fact that we can't drink tea before going to bed, don't always drink overnight tea in normal times, you can drink it once in a while, but if you always drink overnight tea, there are no nutrients, and it is very likely that we will get angry. Overnight tea can be drunk, but not too much, and it will not cause carcinogenicity. It is usually best to drink freshly brewed tea, which is also helpful to wish good health.

There is a scientific basis for this sentence, because it is likely to affect physical health, and there are carcinogenic factors in overnight tea, so drinking too much will cause cancer.

There is a scientific basis for this statement. Because there are a lot of bacteria growing in overnight tea, drinking overnight tea often will cause cancer.

Drinking too much tea overnight can cause cancer, this sentence has no scientific basis, but it is easy to lose sleep.

"Drinking too much tea overnight will cause cancer", this statement actually has no scientific basis。For "overnight tea", most of us define it as tea that has been left out for more than 12 hours. The reason why people think that drinking too much overnight tea can cause cancer is because they believe that overnight tea will produce a carcinogen - nitrosamines when left for a long time.

However, according to scientific investigations, the nitrosamine content of overnight tea is much lower than that of staple foods such as rice, fish and flour in people's daily life. It can be seen from this that "drinking too much tea overnight will cause cancer" is completely alarmist.

Although the nitrosamine content in the overnight tea is not very high, the nutrients in the overnight tea have been greatly lost。Especially in the high temperature environment, free tannic acid substances will be continuously produced in overnight tea, which has a certain negative impact on the human stomach. If the tea is stored in a good environment, the tea can still be drunk even overnight.

It can be seen that whether overnight tea can be drunk depends on whether the tea contains impurities, and this reason also applies to whether overnight water can be drunk.

However, in daily life, people do not deliberately store tea in a good environment. Tea that is left overnight tends to spoil, in which case it is best not to drink the water, but it is also best not to pour it out, because the water has other uses besides not drinking。For example, gargling with overnight tea can effectively reduce oral inflammation and bleeding gums, while using hot overnight tea to wipe the body can effectively relieve itching and remove eczema.

To sum up, drinking overnight tea is not carcinogenic. But from a hygienic point of view, it is best for people not to drink overnight tea, because overnight tea will inevitably deteriorate, resulting in substances that are not good for people's health。For drinking tea, it is best to brew and drink it freshly, which can not only make people drink the best tasting tea, but also reduce unnecessary hygiene problems to a certain extent.

I believe everyone knows the problem of overnight tea, and it is estimated that the most heard is that overnight tea cannot be drunk, and drinking it will cause cancer, but is there a scientific basis for this statement? Then let's talk to you today.

In human food, there are many substances containing nitrates or nitrites, if humans eat them, they can synthesize nitrosamines with secondary amines in the human body, and nitrosamines have a tendency to cause cancer under the unique environmental metabolism in the body. Because of the discovery of nitrite in overnight tea, some people panicked, thinking that they would get cancer after drinking overnight tea. This worry is unfounded.

In fact, nitrite itself is not carcinogenic, it needs certain conditions to have a carcinogenic effect, that is, secondary amines exist in the body and synthesize with them to form nitrosamines. However, the polyphenolic compounds and vitamin C contained in tea have an inhibitory effect on the synthesis of nitrosamines, and not all overnight teas contain nitrites, and even if there are any, the content of some overnight teas is very small. Therefore, the scientific basis for the claim that drinking overnight tea can cause cancer is not sufficient.

There is nitrite in tea, but it is nothing compared to the amount found in other foods such as fish, meat, and vegetables. If drinking overnight tea can cause cancer, then eating overnight fish, meat, and vegetables will cause cancer. However, no such cases have been seen so far.

Professor Zhang, a famous tea expert in China, is a professor of tea science of Zhejiang Agricultural University, who specializes in making a cup of tea at night and drinking it the next morning. From this point of view, the argument that drinking overnight tea causes cancer cannot be established from theory to practice. This is not to encourage people to drink overnight tea.

Any food is best made fresh by the fresh, and tea is no exception. Tea is brewed and drunk as you go, which not only has a strong aroma, but also retains nutrients, and can also reduce the chance of bacterial contamination. Especially in the season of high incidence of intestinal infectious diseases, drinking tea soup overnight will create convenient conditions for the spread of pathogenic bacteria.

Therefore, it is best to brew and drink tea freshly, not overnight tea.

Recent studies have found that overnight tea, when used properly, can also have a number of benefits.

1. Hemostasis. Overnight tea can stop capillary bleeding, such as stomatitis, tongue pain, eczema, bleeding gums, etc.

2. Eye-catching. If the eye is congested with conjunctival hyperemia or frequent tearing, it can be effective to wash the eyes with overnight tea several times a day.

3. Fresh breath. Before brushing your teeth in the morning or after meals, rinse a few sips of overnight tea to freshen your breath and fix your teeth.

4. Protect your hair. Overnight tea can be used to wash your hair as it has anti-itching, hair growth, and dandruff removal effects.
