So, what are the disadvantages of drinking too much tea?
1, which hinders the absorption of iron by human body.
Tea contains tannic acid, black tea contains about 5%, and green tea contains about 10%.
When people drink a lot of strong tea, the combination of tannic acid and iron will be more active, which will hinder and affect the absorption of iron, often manifested as iron deficiency anemia.
2, leading to elevated blood pressure and heart failure.
Caffeine in strong tea will excite people's brains, make their hearts beat faster, and thus raise blood pressure.
At the same time, a large amount of strong tea liquid enters the blood vessels, which will increase the burden on the heart, produce discomfort symptoms such as chest tightness and palpitation, and aggravate the degree of heart failure.
3, affecting normal digestion
The normal gastric juice secreted by a person every day is 1.5-2.5 liters, which can reasonably digest the food that a person takes in every day.
Drinking a lot of tea will dilute the gastric juice, reduce the concentration of gastric juice, make the gastric juice unable to digest food normally, cause indigestion, abdominal distension, abdominal pain and other symptoms, and even cause duodenal ulcer.
4, leading to constipation
Tannic acid in tea can not only combine with iron, but also with protein in food, forming a large amount of tannic acid protein, which is difficult to digest and absorb, thus leading to constipation.
5, increase the burden on the kidneys.
Drinking too much tea will increase water in the body. Frequent urination in the kidney will increase the burden on the kidney and hurt the kidney.
