Some notes when drinking tea
Tea is very good for health, but in addition to those good effects, if you drink tea incorrectly, it will be harmful, so when drinking tea, you should avoid the following:
- Boil or steep tea at high temperatures: At that time, the substance The tannin in tea is dissolved in water, the aromatic oil evaporates, and vitamin C and other nutrients are decomposed, causing harm to health. The water for making tea should only be about 80 degrees Celsius. Many people like to drink a cup of hot tea, not knowing that the temperature of the tea is too high, which is related to the risk of esophageal cancer. On the contrary, you should not let the tea cool down before drinking, it can easily cause a cold stomach.
- Drinking strong tea: Strong tea means a very high amount of tannin. Regularly consuming large amounts of tannin will lead to vitamin B deficiency, constrict the stomach lining, cause protein precipitation, and affect digestive function. Strong tea also reduces the ability to absorb iron in food, leading to anemia over time. Strong tea rich in caffeine also causes headaches and insomnia.
