In other words, Pu'er tea has really been pushed to the forefront in recent years. Our Chinese tea culture is so long, and there are various types of tea, but Pu'er tea seems to have become the target of public criticism.
Let's just say that a few days ago, the editor posted an article about drinking tea, and the comment area really exploded.
Some netizen Lin Xingkong said: "Pu'er tea is a decoration in my home, and I haven't touched it, I still think that green tea is more suitable for my taste and feels healthier." ”
He Jing also left a message: "The older the wine, the more fragrant it is, but the tea is not like that." Pu'er tea has been left for a long time, and I don't dare to drink it, no matter how those merchants blow. ”
Uncle Li Jun was more direct: "Pu'er tea is pressed like that, I can't tell if it's good or bad, if it's moldy, what can I do?"
There are even rumors that "there is mold in Pu'er tea, and 500 million mold will enter the stomach after drinking it", and some people even say that it can cause cancer.
Oh, this has come and gone, and the status of Pu'er tea in everyone's hearts has plummeted. Now many people are asking, can this Pu'er tea still be drunk, and are those rumors true or false?
Hey, speaking of which, I also feel quite helpless. In fact, Pu'er tea is a good thing, but it was hurt by these rumors.
Let's drink tea just to be healthy and happy, why is it making people panic now. I hope everyone can distinguish between right and wrong, and don't be blinded by these false rumors.

The term ripe tea is often misunderstood as boiled tea leaves, or as opposed to raw tea, it refers to unprocessed tea leaves.
However, this is not the case. The definition of ripe tea originates from Yunnan Province, which is a special type of tea, which is made from Yunnan large-leaf sun-dried green hair tea as raw material and processed by artificial Wudui fermentation and other processes.
The key lies in artificial fermentation. This process is one of the most significant differences between cooked and raw tea.
The raw material of Pu'er tea is dried green hair tea, which becomes Pu'er raw tea after being picked, dried, finished, rolled and dried. Ripe tea, on the other hand, needs to go through the process of fermentation in Wudui, which is one of the unique processes.
In the process of fermentation, the tea leaves are stacked, moistened, and stirred to promote the growth of microorganisms and fermentation.
This fermentation process simulates the effects of natural aging, accelerating the aging process of the tea leaves. As a result, ripe teas tend to be milder and mellower in taste and smell.
In terms of appearance, there is also a clear difference between ripe tea and raw tea. Ripe teas generally have a darker maroon color, while raw teas often have a green or light yellow color.
This difference in color is mainly due to the chemical reaction during the fermentation process of the wolf, as well as the formation of the characteristic smell of the aged tea leaves.
In addition to pu-erh tea, the category of ripe tea also includes a number of other types of tea, such as black tea and black tea. These teas have undergone a similar artificial fermentation process as Pu'er tea, so they also have a certain aging effect and a special taste.

In recent years, rumors that Pu'er tea contains mold and causes cancer have spread widely, causing public concern and questioning.
To resolve the controversy, the Guangdong Provincial Center for Disease Control and Prevention conducted random tests and experiments on a number of Pu'er teas on the market to detect the presence of excessive mold and the possibility of containing the carcinogen aflatoxin.
In this sampling, 40 brands and 148 samples were involved, covering Pu'er tea products of different years and prices.
Strict testing methods were used in the experiment, including the detection standards of aflatoxin B1.
The results showed that aflatoxin B1 was detected in only a very small number of samples in all samples, and the detection value was very low, well below the national standard limit.
Specifically, aflatoxin B1 was detected in only 3 of the 148 samples, and the detected values were 0.26 μg/kg, 0.407 μg/kg, and 0.56 μg/kg, respectively.
Although these values are slightly above zero, they are still negligible compared to the limits set by national standards. Other mycotoxins were not detected to exceed the limit.
It should be emphasized that the maximum detection value of aflatoxin B1 is close to the minimum limit for infant formula in the national standard, but far lower than other food standards, such as rice and peanut oil.
This indicates that the content of aflatoxin B1 in Pu'er tea is within the food safety range and does not pose an obvious threat to human health.
With the exception of aflatoxin B1, no other mycotoxins were detected. This means that the mold content in Pu'er tea does not exceed the national standard, and the risk to human health is low.

Recently, a research team from the Sixth People's Hospital affiliated to Shanghai Jiao Tong University published a study on Pu'er tea in the internationally renowned academic journal Nature Communications. This study shows that Pu-erh tea may have a positive effect on the regulation of blood lipids.
Studies have shown that Pu-erh tea contains an active substance known as theabrownin. This ingredient is found in relatively high levels in Pu-erh tea and has the ability to regulate the body's intestinal flora and bile acid metabolism. This finding provides a new scientific basis for Pu-erh tea to reduce hypercholesterolemia.
The results showed that theabrownin was able to adjust the structure of the intestinal microbiota, especially to significantly reduce the abundance of bacteria related to the activity of bile salt hydrolase (BSH).
The decrease in BSH activity can promote the production of bile acids and fecal excretion in the liver, thereby reducing the synthesis and accumulation of fat.
This study further deepens the understanding of the health benefits of Pu-erh tea. Although more experimental evidence and clinical studies are still needed to further validate its effect, this finding provides a new idea for the potential application of Pu-erh tea in lipid lowering.
It is important to note that although this study found a possible effect of Pu-erh tea on blood lipid regulation, drinking tea does not completely replace medication or other healthy lifestyles.
Therefore, if you have dyslipidemia or other health problems, you still need to follow your doctor's instructions for comprehensive treatment and management.

Drinking tea is a daily habit for many people, but the right way to drink tea is essential for good health. Here are five things you need to know about drinking tea:
01Don't drink hot tea
Some people tend to brew tea leaves with freshly boiled water and then drink them immediately, especially gongfu tea.
However, overheated tea leaves may burn the esophageal mucosa, increasing the risk of esophageal and stomach cancer.
The best temperature to drink tea is around 50°C, you can use boiling water to make tea, but please wait a while before drinking.
02 Drink less strong tea
Strong tea contains a higher content of tannic acid, which may hinder iron absorption, and excessive caffeine intake may cause discomforts such as rapid heartbeat, heart palpitations, etc.
Therefore, when brewing tea, it is necessary to pay attention to controlling the number of tea leaves and avoid overly strong tea.
03Don't drink tea on an empty stomach
Drinking tea on an empty stomach may increase the stimulation of caffeine and tannic acid to the stomach, while some active substances in tea may combine with the protein in the stomach to promote gastric acid secretion, which is not conducive to the health of the stomach. Therefore, it is best to drink tea after eating.
04 Don't drink tea to cure hangover
Some people like to drink strong tea after being drunk to cure hangovers, however this is not the right thing to do.
When drunk, heart rate and respiratory rate increase, while theophylline and caffeine in tea may further accelerate the heart rate and increase the burden on the heart rather than relieve the discomfort after drinking.
05Drink less sweetened tea drinks
When buying tea drinks, it is advisable to choose sugar-free or low-sugar products, and it is best to brew your own tea.
Although some tea drinks are in the name of tea, they contain a lot of sugar, which not only makes the tea lose its original flavor, but also increases the intake of sugar, which is not good for health.
