1, avoid drinking green tea for the first time.
Because green tea is polluted by harmful substances such as pesticides in the process of planting and processing, there are always some residues on the surface of green tea. Therefore, the first kind of green tea has a washing function and should be abandoned.
2. Avoid drinking green tea on an empty stomach
Drinking green tea on an empty stomach will dilute gastric juice, reduce digestive function, and the absorption rate of water is high, which will lead to a large number of bad ingredients in green tea entering the blood, which will not only lead to dizziness, but also cause palpitations sometimes, so it is best not to drink green tea on an empty stomach.
3. Drink less new tea.
Because of the short storage time of new green tea, it contains more unoxidized polyphenols, aldehydes and alcohols, which has a strong stimulating effect on human gastrointestinal mucosa and is easy to induce stomach diseases. Therefore, drink less new green tea and avoid new green tea stored for less than half a month.
4, people with cold stomach should not drink more.
Attention, everyone. Friends with stomach cold should never drink too much green tea in their lives, otherwise it will cause gastrointestinal discomfort. People with neurasthenia and insomnia should not drink green tea before going to bed, and lactating women should also drink less green tea, because green tea has a astringent effect on milk.
5, avoid using green tea to take medicine, avoid drinking green tea overnight.
Tannic acid in green tea will combine with many drugs to produce precipitation, which will hinder absorption and affect the efficacy. As the saying goes, "green tea water can detoxify", vitamins have been lost after green tea is left overnight, and nutrients in green tea will become nutrients for bacteria and mold reproduction.
What are the taboos and precautions for drinking green tea? I believe everyone has an understanding of this problem through the above introduction, and should pay more attention to it in life. In addition, it is best not to drink green tea on an empty stomach, otherwise it will be harmful to your health.
