Tea drinking is an important part of China's diet and health regimen. It has been thousands of years since guests came to respect tea, replaced tea with tea, and used tea as a gift.
With the deepening of scientific research, in recent years, knowledge about the nutritional composition, pharmacological properties, and health value of tea has gradually become popular. Tea drinking and love for the whole people have become common practice. The traditional tea culture of the Chinese nation has also entered a new historical development. stage.
At present, health issues and food safety are highly valued, and a number of scientific experiments have shown that drinking Pu'er tea is also essential for health.
Following the previous issue of tea food safety knowledge-Healthy Pu'er Tea, this issue continues to introduce the introduction of Pu'er tea's health and health functions to the majority of tea friends.

\
01 Mitigation of Harm of Smoke
\
Scientific research shows that Pu'er tea can slow the harm of tobacco poison to human body. Researchers at the Yunnan Key Laboratory of Animal Nutrition and Feed have found that Pu'er tea can reduce the blood nicotine concentration, and the longer the drinking time, the more significant the effect. This not only directly reduces the harm of nicotine inhalation, but also has a potential to alleviate the "smoking addiction". efficacy.
\
\
Pu'er tea can also reduce the concentration of carbon monoxide in the blood of passive smokers, improve the oxygen-carrying function of the body, and alleviate the harm of tobacco poisoning. It has been proven that Pu'er tea has a direct effect on alleviating the harm of tobacco poisoning. Smokers or people who have been exposed to smoking for a long time can reduce the harm caused by smoking by drinking Pu'er tea for a long time.
02 Helps lower blood sugar
\
Scientific research shows that both Pu'er tea (raw tea) and Pu'er tea (cooked tea) can help lower blood sugar. Scientists have tested animal models of diabetes and found that Pu'er tea can improve the insulin receptor sensitivity of type 2 diabetes, thereby reducing blood sugar, but has no effect on blood sugar in normal organisms. The principle of its hypoglycemic effect is not to increase the body's insulin level, but to interfere with the insulin receptor to achieve its beneficial effects.
\
\
The hypoglycemic effect of Pu'er tea on type 1 diabetes is to increase the body's insulin level, and at the same time, it can alleviate the symptoms of "drink more" and "eat more" caused by diabetes. At present, further research on the role of Pu'er tea in lowering blood sugar is still underway.
03 Cancer Prevention
\
Scientific research shows that Pu'er tea has an auxiliary inhibitory effect on tumors, and its effect in preventing tumors is more prominent. After more than ten years of research, experts from the institute found that Pu'er tea has a variety of rich anti-cancer vitamins (such as β-carotene, vitamins B1, B2, C, E, etc.) and many extremely important anti-cancer trace elements (chromium , Manganese, selenium, zinc), its tumor prevention effect is the result of the interaction of multiple active ingredients.
\
\
After the action of Pu'er tea , lethal mutations in the morphology of cancer cells have occurred. These changes prove that under the action of tea, cancer cells change from degeneration to death.
04 Sterilization and anti-inflammatory
\
According to research, Pu'er tea extract has anti-HIV activity, which can inhibit HIV-induced cells to form syncytia and effectively protect MT-4 cells. It is a natural source of anti-HIV activity products with great potential and has good development and application. prospect.
In addition to HIV, Hepatitis B virus (HBV) is also a worldwide infectious virus. Extracts of Pu'er tea can effectively reduce the secretion of hepatitis B virus e antigen and inhibit HBV mRNA expression.
Some scholars have studied the effects of Puer tea (raw tea), Puer tea (cooked tea), and decaffeinated tea extracts on E. coli. Compared with the control group, E. coli in the three experimental groups were inhibited, and Pu'er tea (Cooked tea) has better antibacterial effect than Puer tea (raw tea). Puer tea extract can significantly inhibit Listeria monocytogenes, Salmonella typhimurium, Bacillus anthracis, Streptococcus, and Staphylococcus aureus.
