What are the taboos of drinking green tea?
1. The green tea that has just come on the market will take a while to drink
Although early spring green tea is as expensive as gold. I just want to take a sip of the green tea I just bought. However, old tea farmers say, because green tea is usually roasted and roasted. Freshly processed green tea will inevitably have anger, and drinking too much too early will cause anger. Therefore, it is only necessary to store the processed tea leaves for about half a month, and when the anger dissipates, it can be used with confidence.
2. Do not take cold medicine and metal supplements with tea
There are a lot of tannins (tannic acid or tea tannins) in tea leaves. Cold medicine contains alkaline substances. Neutralization of the two will greatly reduce the medicinal properties of the drug. In addition, caffeine and theophylline in tea have the effect of strengthening the heart and diuresis, and refreshing the brain. Excessive consumption during a cold can cause the human heart to beat fast, and being too excited is not good for the heart.
Secondly, because tea polyphenols in tea will chemically react with metal ions. (complexation reaction), reducing the efficacy of the drug. Therefore, such as calcium tablets (calcium lactate, calcium gluconate), iron-containing (iron-containing blood, ferrous sulfate, ferrous carbonate), aluminum-containing ("aluminum hydroxide" for treating hyperacidity, Weishuping "compound") Aluminium hydroxide", analgesic "aspirin", etc.) and cobalt-containing drugs cannot be taken with tea.
3. Do not drink tea immediately after meals
The aromatic compounds in green tea can dissolve fat; caffeine, vitamin B1, etc. can promote gastric acid secretion and achieve digestion. Therefore, green tea can promote gastrointestinal motility and help digestion. However, green tea is cold in nature, and taking it immediately after meals will cause damage to the stomach. Therefore, it should be more appropriate to drink tea at least 30 minutes after a meal.
4. Do not drink tea on an empty stomach
Green tea is cold in nature, and drinking green tea directly on an empty stomach will stimulate the stomach. At the same time, tea will dilute gastric juice and reduce digestive function.
5. It is not advisable to drink tea before going to bed
Tea contains a lot of caffeine theophylline. Drinking tea before going to bed can easily excite nerves and cause insomnia. Especially freshly picked green tea, the stimulating effect is more obvious.
When is it good to drink green tea?
Drink green tea one hour after meals and two hours before going to bed. At this point, green tea can help with digestion and hydration. Do not drink tea immediately before and after meals, because drinking tea immediately after meals, tannic acid in tea can combine with iron in food to form insoluble iron salts, reducing iron absorption, and it is easy to induce anemia after a long time. After hours, the iron in the food has basically been absorbed, and drinking tea at this time will not affect the absorption of iron. Do not drink tea before going to bed, it will affect sleep.
It is not suitable to drink green tea on an empty stomach. Drinking tea on an empty stomach will meet Changwei Shang, especially for people who do not drink tea often. If you drink tea on an empty stomach, it will easily inhibit the secretion of gastric juice, hinder digestion, and even cause palpitations, headaches and other "tea drunk" phenomena.
How to drink green tea?
1. The upper pouring method: first pour enough hot water into the teacup (tea bowl) at one time, and then put the tea leaves when the water temperature is moderate. This method is mostly suitable for tender fried greens (such as super Longjing, super Biluochun, super Xinyang Maojian, Lu'an melon slices, Laozhu Dafang, etc.), tender roasted greens (such as Zhuxi Longfeng, Tingxi Lanxiang, Huangshan Maofeng, etc.) Taiping Houkui, Jingting Luxue, etc.) and other green teas with excellent delicacy. In this method, the water temperature should be controlled very accurately. The more tender the tea leaves, the lower the water temperature requirements. Some tea leaves can be placed at 70°C. Therefore, the usual drinking operation is difficult and not very convenient.

This method is suitable for green tea that is tender but very loose or firm (such as Yingshan Yunwu, Zhuyeqing, Wuyuan Mingmei)
3. Lower pouring method: put the tea leaves first, and then pour enough hot water into the teacup (tea bowl) at one time. This method is suitable for general green tea with poor tenderness.
