But tea contains substances such as alkali.
Drinking too much will affect the stomach.
Eating too much is harmful and may also lead to stomachache.
People with stomachache are advised not to drink green tea.
It should be reminded that tea contains a lot of polyphenols, which are easily condensed with protein, iron and other substances, and are not easily absorbed by intestinal mucosa, which affects the digestion and absorption of protein and iron. Therefore, it is not advisable to drink tea immediately after eating high-protein foods such as seafood and bean products.
If the tea polyphenols in tea are attenuated (converted into other substances) for various reasons, the irritation of tea to the stomach will be reduced. For example, natural oxidation (such as aged white tea), enzymatic oxidation (such as black tea) and microbial fermentation (such as Pu 'er cooked tea or aged Pu 'er raw tea). Therefore, if the stomach is not strong enough, you can drink more fermented tea or old tea, such as black tea, black tea or old white tea.
