It is certain that cooked tea causes cancer. Pu 'er tea is one of the favorite teas of female compatriots. You can get greasy and lose weight. In fact, Pu 'er tea has a good effect on our health, but some people say it will cause cancer. Let's take a look at the related contents of cancer caused by cooked tea.
It is certain that cooked tea causes cancer. People have been arguing endlessly about the claim that cooked tea causes cancer. Some people think that ripe Pu 'er tea should be drunk with caution, otherwise it will cause cancer. Some people think that cooked Pu 'er tea has certain efficacy and can play a good role in the body.
Cooked Pu 'er tea does not necessarily cause cancer.
Cooked tea does not necessarily cause cancer, because well-preserved Pu 'er tea does not cause cancer, and only cooked tea containing aflatoxin and other substances will cause cancer. The reason why cooked tea contains aflatoxin is mostly caused by improper preservation.
Aflatoxin is a secondary metabolite produced by Aspergillus flavus and other parasitic aspergillus under certain conditions, which can only be produced if it meets both material requirements and environmental requirements. Therefore, it is recommended to seal the cooked tea when it is stored.
Generally speaking, if cooked tea is wet and not dried in time, aflatoxin will be produced. Cooked Pu 'er tea containing aflatoxin generally has a kind of moisture and smells sour, which is the key to distinguish cooked Pu 'er tea.
When choosing ripe tea, it is suggested to choose ripe tea with rich fragrance and crisp pinch first. This kind of Pu 'er tea is well-preserved, has high drinking and collection value, and has the functions of promoting fluid production to quench thirst, disinfection and sterilization.
Is Pu 'er tea carcinogenic?
Pu 'er tea or any food, as long as carcinogens, such as aflatoxin, are detected, then this product must be contaminated and must not be taken. No matter how much it contains, be alert. Aflatoxin detected in Pu 'er tea is generally moldy and deteriorated, which belongs to unqualified products.
Pu 'er tea itself does not produce aflatoxin, as long as it is in a qualified storage environment. Avoiding secondary pollution is what we should pay attention to, such as the storage environment after buying it back. And the processing and production of Pu 'er tea must be carried out in strict accordance with the comprehensive standards of Pu 'er tea.
Aflatoxin is a secondary metabolite produced by Aspergillus flavus and other parasitic Aspergillus under certain conditions. It must meet the material and environmental conditions. Pu 'er tea itself is impossible to produce aflatoxin, and it also lacks the material conditions to transform aflatoxin.

In fact, aflatoxin is nothing new. If all grains are not dried in time or stored in a hot and humid environment, they are often easily contaminated with such toxins, such as common peanuts, corn, rice and some nuts. Exceeding the standard is common. You will appear in Pu 'er tea, which is highly related to its storage environment. However, it cannot be considered that aged Pu 'er tea contains yellow koji toxin, which is extremely imprecise.
Tea mountain
As we said above, Pu 'er tea itself does not produce aflatoxin, so where is the problem easy to appear? After artificial post-fermentation of environmental Pu 'er tea, workers do not pay attention to the cleanliness of the environment, and some related impurities appear, which is easy to cause secondary pollution. The wet warehouse has not been recognized by everyone, and I think this is also one of the reasons. Therefore, there must be a correct value judgment when buying.
tea
Every time someone says that Pu 'er tea is carcinogenic, it will lead to a crazy discussion. That's understandable. After all, food safety is the most concerned point now. However, you have seen a product, and it can still be recognized after several low tides. This is definitely not an accident, but has its own value. Don't just say that Pu 'er tea is carcinogenic. I still don't think tea is necessary. You can drink it if you like. You don't have to drink if you don't like it. Nobody forced you. Don't be ugly if you don't drink it.
It is certain that cooked tea causes cancer. Is it certain that Pu 'er tea causes cancer?
Since Pu 'er tea came into our sight, many people who want fire have also come into our sight. They made irresponsible remarks such as "Pu 'er tea is fermented in pigsty", "Pu 'er tea causes calcium loss" and "Pu 'er tea causes cancer", which made many consumers believe it for a while, especially the incident of "Pu 'er tea causes cancer". Li Jianjun, a professor of ergonomics, first proposed in Weibo that drinking Pu 'er tea is the fastest way to get cancer. The second time, Fang wrote that drinking Pu 'er tea will cause cancer because of aflatoxin, which led many people to generalize that all Pu 'er tea is easy to cause cancer as long as it goes through the later period of Chen Fang.
How to distinguish the quality of Pu 'er tea?
The first point is to smell the aroma, mainly the purity of the aroma, because the old aroma of Pu 'er tea is always misled into musty taste, which is an uncomfortable taste. Old aroma is the comprehensive aroma of Pu 'er tea in the post-fermentation process, which will make people feel happy.
Longan fragrance, red date fragrance, betel nut fragrance, etc. They are all good-smelling Pu 'er tea, and good Pu 'er tea has an old rhyme in it, so the old taste must be separated from the musty taste. If there is musty, sour or other peculiar smell, fragrance, etc. It's all bad tea.
The second point is to look at the soup color of Pu 'er. The most distinctive feature of Pu 'er is "red". In terms of quality, the best is ruby red, followed by agate red and amber red. Tea soup will be as light as water when it becomes Huang Shi, and the aging period is not enough. If the soup is brown and black, turbid and has suspended matter, it means that Pu 'er tea has gone bad.
Is it certain that Pu 'er tea causes cancer? What is the truth?
The third and most important point is the taste. When tasting Pu 'er, it's best to drink a little bigger, make a detour in your mouth, let the tea smell fill your mouth, and then swallow it, so that you can feel the viscosity of the tea soup, distinguish the quality of the tea, and also feel the thick and full tea soup, and the taste is smooth.
A good cup of Pu 'er tea will make you feel cool and warm in your throat, and then it will be sweet and fragrant. This charm will be brought into your mouth with your breath when you breathe. At this time, you will feel that your forehead and throat also have a sweet fragrance. Some people think that tea is bitter, in fact, it is bitter because of the problems of tea itself, but Pu 'er after cooling will also be bitter, but slowly taste the tea fragrance, return to sweetness, produce saliva and be sweet.
The taste of ordinary tea leaves will be weakened after six times of brewing, but the ancient Pu 'er tea leaves are basically maintained at about 10, and a small amount of sustainable 12 brewing is above. What can brew for more than 20 times may be that the brewing method is not standardized, just like a tea shop only needs to put tea leaves for a long time. After the water is boiled, stop heating and brew for a longer time.
It is certain that cooked tea causes cancer. 3. The efficacy and taboo of Pu 'er tea.
efficacy
Traditional Chinese medicine believes that Pu 'er tea has the functions of clearing away heat and relieving summer heat, detoxicating and promoting digestion, relieving fatigue, promoting diuresis and relaxing bowels, eliminating phlegm and expelling wind, relieving exterior syndrome and relieving cough, promoting fluid production and benefiting qi, and prolonging life.
These statements are ridiculous. After all, it takes some processing to use tea as medicine.
The research on the efficacy of Pu 'er tea in modern medicine is even more exaggerated, that is, Pu 'er tea has the effects of warming stomach, losing weight, lowering blood fat, preventing arteriosclerosis, preventing coronary heart disease, lowering blood pressure, resisting aging, anticancer, lowering blood sugar, inhibiting bacteria and diminishing inflammation.
It has more than 20 functions, such as reducing tobacco poison, reducing heavy metal poison, resisting radiation, preventing dental caries, improving eyesight, helping digestion, resisting poison, preventing constipation and relieving alcoholism.
Among them, the effects of warming stomach, losing weight, reducing blood fat, preventing arteriosclerosis, preventing coronary heart disease, lowering blood pressure, anti-aging, anticancer and lowering blood sugar are particularly prominent.
Reduce blood fat, lose weight, lower blood pressure and prevent arteriosclerosis.
Anticancer, anticancer
Nourish and protect the stomach at an appropriate concentration.
To protect teeth, Pu 'er tea contains a variety of physiologically active ingredients.
Anti-inflammatory, sterilization and treatment of dysentery.
Anti-aging: Catechin in tea has anti-aging effect.
In addition, the fermented Pu 'er cooked tea is rich in probiotics and has high nutritional value. Most of the probiotics in Pu 'er tea are formed during the fermentation of cooked tea.
Through fermentation, under the action of microorganisms, the aroma components, tea polyphenols and other chemicals in tea have undergone structural transformation, which will show unique tea characteristics and health care effects.
Pigments and dyes: Pu 'er tea is rich in pigments, which are widely used. It can be used not only to mix wine, but also to make food.
If you prepare a little Pu 'er tea juice in the kitchen, it is much better than ordinary chemical pigment seasoning dishes, and it can also be used to dye cloth, which can be dyed in various colors.
Organic fertilizer: the brewed Pu 'er tea still contains inorganic salts, carbohydrates and other nutrients. If it is buried in flower beds or flowerpots, it will help the development and reproduction of flowers and plants.
Friends who like potted plants generally know this purpose, which is much more convenient than garbage disposal.
Detergent: Tea leaves can remove dirt and fatigue, so washing your hair with tea leaves can make your hair black, soft and shiny.
After a few times, the average lady will feel much better than some shampoo or something.
Because tea contains no chemicals, it will not harm hair and skin. Taking a bath with Pu 'er tea in boiling water can not only remove body odor and dirt, but also maintain the skin.
Bathing with tea can reduce the occurrence of skin diseases and make the skin shiny, smooth, soft and fat-free.
taboo
1, avoid drinking new tea: because new tea has a short storage time, it contains more unoxidized polyphenols, aldehydes and alcohols, which has a strong stimulating effect on human gastrointestinal mucosa and is easy to induce stomach diseases.
Therefore, drink less new tea and avoid new tea that has been stored for less than half a month.
2, drinking tea on an empty stomach: drinking tea on an empty stomach will dilute the gastric juice, reduce the digestive function, and the water absorption rate is high, resulting in a large number of bad ingredients in tea entering the blood, causing dizziness, palpitation, weakness and other symptoms.
3, have a fever to drink tea: tea contains theophylline, which has the effect of raising body temperature. Drinking tea with a fever is tantamount to "adding fuel to the fire."
4, drinking tea during menstruation: drinking tea during menstruation, especially drinking strong tea, will induce or aggravate menstrual syndrome.
Medical experts have found that compared with people who don't drink tea, people who have tea habits are 2 or 4 times more likely to have menstrual tension than those who don't drink tea, and those who drink more than 4 cups a day are 3 times as likely as those who don't drink tea.
5. Avoid drinking tea for patients with liver disease: most substances such as caffeine in tea are metabolized by the liver. If the liver is sick, drinking too much tea will exceed the metabolic capacity of the liver and damage the liver tissue.
6, pregnant women avoid drinking tea, especially not strong tea: tea contains a lot of tea polyphenols, caffeine and so on. This has many unfavorable factors for the growth of the fetus in the mother's womb.
In order to make the fetus' intelligence develop normally and avoid excessive stimulation of caffeine to the fetus, pregnant women should drink less or not drink tea.
