In today's society, tea drinking has become an indispensable part of many people's lives. Tea culture has a long history, not only carrying a profound historical heritage, but also containing a rich concept of health. However, in the process of tasting tea, many people often fall into some misunderstandings, which leads to the backfire of tea drinking. Today, let's explore the four major misunderstandings of tea drinking and reveal the scientific truth.

1. Can strong tea really anti-aging?

Lao Zhao, a retired old man, likes to make tea in the yard to entertain friends. He is particularly fond of strong green tea, and he brews two packets each time. His friend Lao Li expressed concern about this, believing that long-term consumption of strong tea may be bad for health. So, does strong tea really anti-aging?

Recently, a study was published in the journal The Lancet, conducted by the West China School of Public Health, Sichuan University. The researchers surveyed participants from the UK Biobank panel and the South West Regional Population Nature Row study, and found that the signs of aging were significantly slowed in those who drank tea consistently. Specifically, people who drink about 8 cups or 0 to 0 grams of tea per day have the best anti-aging effect.

Tea contains a variety of bioactive compounds such as polyphenols, purine alkaloids, theanine, and caffeine, which have antioxidant, radiation, and anti-aging effects. In particular, tea polyphenols can effectively remove free radicals in the body and delay the aging process. However, despite the higher content of these beneficial components in strong tea, it does not mean that the stronger the tea, the better.

Long-term consumption of strong tea can lead to excessive intake of substances such as oxalic acid, caffeine, and theophylline, which can lead to a range of health problems. For example, the caffeine and theophylline in strong tea may irritate the central nervous system, leading to insomnia; Oxalic acid, on the other hand, may increase the risk of kidney stones. Therefore, it is wise to drink weak tea in moderation.

2. Is drinking tea cancer-preventing or carcinogenic?

It has been widely said that drinking tea causes cancer. Some people claim that Pu'er tea contains a lot of mold and xanthromycin, which can cause cancer when consumed regularly. However, this is not the case.

Pu'er tea is artificially fermented, mainly using microorganisms such as Aspergillus niger and Rhizopus. These microorganisms are harmless to humans. In fact, normally fermented Pu-erh tea is safe to drink under reasonable storage conditions. In addition, overnight tea is not too much to worry about. Studies have shown that the nitrite content in overnight Pu'er tea, chrysanthemum tea and Longjing tea is lower than the national standard.

On the other hand, drinking tea is also believed to have certain anti-cancer effects. A study published in Advances in Nutrition found that drinking tea has a positive effect on the prevention of cancers such as oral cancer. Chen Zongmao, an academician of the Chinese Academy of Engineering, has introduced a Japanese study that showed that women who drink 2 small cups of tea (0 ml per cup) per day can delay the onset of cancer by an average of 0.0 years, and men can delay it by 0.0 years.

However, drinking tea is not a substitute for formal medical treatment. Although tea contains a variety of beneficial substances, daily tea consumption cannot be used as a cure for cancer. Blindly relying on tea to treat diseases will only delay the best time for treatment.

3. The four major misunderstandings of reverse tea drinking

Tea drinking is good, but the wrong way to drink tea can be counterproductive. Here are four common myths:

Aged tea is not washed

Black tea and oolong tea are mostly aged teas, and it is best to wash them with boiling water for 20 to 0 seconds before brewing, and then pour them out to make tea. Doing so not only removes possible microorganisms, but also promotes the volatilization of the tea aroma.

Brew green tea with boiling water

Green tea should not be brewed with boiling water, it is recommended to use water from 85 to 0 degrees Celsius. Boiling water may destroy the vitamin C and amino acids in green tea, affecting the taste and nutritional value.

Drink tea and sober up

Although drinking tea can accelerate the decomposition and excretion of alcohol, it may increase the burden on the liver and kidneys, especially for people with poor liver and kidney function, it is not suitable to drink tea after drinking.

Chewing tea residues to maintain health

It is not recommended to chew and swallow tea grounds because tea grounds may contain trace amounts of heavy metals and insoluble pesticides, which are not good for human health.

In conclusion, drinking tea is a healthy lifestyle, but you need to pay attention to the correct way to drink tea. Avoid falling into pitfalls in order to better enjoy the health benefits of tea. Let us pay more attention to scientific tea drinking while tasting tea, and let the fragrance of tea accompany us through every good time.
