It is ok to drink too much tea occasionally to relieve boredom, but it is unrealistic to hope to lose weight by drinking tea. What we should do more is to pay attention to the balance of diet intake and proper exercise.

Drink tea in moderation, but don't drink a lot of strong tea at night. And if you drink tea immediately after a meal, it will cause indigestion because of excessive stimulation to the gastrointestinal tract, and it will increase the risk of stones because of tannic acid and theophylline. So, drink tea half an hour after dinner.

Unpleasant tea

1, deteriorated tea

Tea is not easy to keep properly, and it is easy to absorb moisture and mold. Deteriorated tea contains a lot of substances and germs harmful to human body and cannot be drunk. If high-quality tea leaves are left for too long after soaking, the tea soup will also deteriorate due to oxidation and microbial reproduction, and such tea can no longer be drunk.

2, the first tea

Because tea is inevitably polluted by pesticides, fertilizers, dust and other substances in the process of planting, processing and packaging. The first sip of tea is actually the water for washing tea, so it is necessary to rush into boiling water as soon as possible, so that the brewed tea is the most hygienic tea.

3. Leng Cha

Drink tea when it is hot and humid. Herbal tea has the disadvantage of cold stagnation and phlegm accumulation. In other words, warm tea and hot tea can make people think clearly and keep their ears clear; Herbal tea has the side effect of cold coagulation and phlegm accumulation.

4. Hot tea

Tea is usually brewed with high-temperature water, and you can't drink it if the water temperature is too hot. Too hot tea irritates throat, esophagus and stomach. If you drink too hot tea for a long time, it may cause pathological changes in these organs.

5. Make tea for a long time

If the brewing time is too long, tea polyphenols, lipids and aromatic substances in tea will automatically oxidize, which will not only make the tea soup darker in color, worse in taste and lower in aroma, but also lose its taste value; Moreover, because vitamin C, vitamin P and amino acids in tea are reduced due to oxidation, the nutritional value of tea soup is also greatly reduced. At the same time, because the tea soup has been put on hold for a long time and is polluted by the surrounding environment, there are many microorganisms (bacteria and actinomycetes) in the tea soup, which is very unsanitary.
