Why you should try to avoid oolong tea as much as possible
The main reason to avoid oolong tea as much as possible is that it can irritate the stomach, affect nutrient absorption, worsen constipation, affect the efficacy of medication, and cause anaemia.
First, the oolong tea’s stimulation of the stomach is not to be ignored. Oolong tea is a semi-fermented tea, which is relatively more stimulating to the stomach. Drinking a lot of it for a long time may cause damage to the stomach and induce diseases such as gastritis. Tannic acid in tea can easily irritate the gastric mucosa, causing symptoms such as acid reflux, belching, and nausea. In the long term, it may also affect digestion and even cause constipation.
Another important reason is that oolong tea may affect nutrient absorption. Oolong tea contains a lot of tannic acid, which, when combined with nutrients such as iron and zinc in food, may affect the body’s absorption of these nutrients. Therefore, it is best to avoid drinking oolong tea immediately before or after a meal to avoid affecting nutrient intake.
In addition, oolong tea may cause constipation to worsen, which is also a concern. The polyphenols in oolong tea have a certain astringent effect on the gastrointestinal mucosa, and patients with frequent constipation may experience worsening constipation symptoms when drinking oolong tea.
In addition, oolong tea’s effect on drug efficacy is also an aspect that requires attention. The theophylline in oolong tea can increase body temperature, weakening or counteracting the cooling effect of drugs. Therefore, you should avoid drinking oolong tea while taking drugs.
Finally, oolong tea may cause anemia, which is also a concern. The tannins in oolong tea can cause iron in food to form a precipitate that is not absorbed by the body. Frequent consumption of oolong tea may lead to worsening of anemia symptoms.
In summary, although oolong tea has certain health benefits, in order to avoid the above discomforts and potential health risks, it is recommended to drink it in moderation, avoid drinking on an empty stomach and avoid excessive consumption, especially in certain populations.
