While new tea is good, it can easily trigger various diseases
If the tea has been stored for a short time, the content of unoxidized polyphenols is high, and they have a strong stimulating effect on the human gastrointestinal mucosa. Fresh tea also contains more caffeine and theophylline, which can easily lead to high excitement of the nervous system, causing symptoms such as insomnia, headache, fatigue, sweating, and frequent urination.
During the Spring Festival, Professor Wang's students came to pay a New Year's visit and brought a potted green tea all the way from the south. The students told Professor Wang that this type of potted green tea had just become popular in places like Fujian, claiming it could absorb computer screen radiation and improve indoor air quality. When purchasing it, the merchant also recommended that brewing fresh tea leaves in water could improve the body's microcirculation and prolong life.
A few days ago, seeing the potted green tea had lush branches and leaves, Professor Wang picked a few tender leaves to brew into tea. That evening, Professor Wang began to experience symptoms such as stomach pain, dizziness, fatigue, and night sweats, and rushed to a nearby hospital for emergency treatment. After an examination, Professor Wang was diagnosed with theophylline poisoning, and the cause was traced to the potted green tea at his home.
Tea also comes in different varieties, and not all teas are better the fresher they are. Pu-erh tea and dark tea are better when aged, while green tea is prized for being fresh. It's the season for spring tea to hit the market, and when people enjoy tea, they often prefer new tea for its fresh and tender quality. Mingqian tea, picked before the Qingming Festival, and Yuqian tea, picked before the Rain Water solar term, are often highly sought after by consumers. But even green tea is not meant to be consumed immediately after picking.
If the tea has been stored for a short time, the content of unoxidized polyphenols is high, and they have a strong stimulating effect on the human gastrointestinal mucosa. For those with weaker gastrointestinal function, especially patients with chronic gastritis and ulcers, drinking new tea can cause stomach pain, bloating, and other issues. Fresh tea also contains active tannic acid, which can solidify proteins and iron in food, affecting digestion and absorption.
In addition, fresh tea also contains more caffeine and theophylline, which can easily lead to high excitement of the nervous system, causing symptoms such as insomnia, headache, fatigue, sweating, and frequent urination. Therefore, new tea should also be stored for a period of time, allowing substances like polyphenols in the tea to oxidize naturally, reducing the stimulation to the stomach and intestines before it can be brewed and consumed.
