Frequent drinking of tea is harmful to the body, as follows:

1. Causes stomach discomfort: Regular drinking of large amounts of strong tea can easily cause some discomfort to the body, which can easily lead to stomach discomfort. The dilution of gastric juice causes food to not be digested well after entering the intestines, leading to a series of gastrointestinal diseases, such as indigestion, bloating and other symptoms.

2. Constipation is prone to occur: Long-term tea drinking will cause the tannic acid in the tea leaves to combine with the iron in the body, and also combine with the protein in the food to form pieces of tannic acid that are not easy to digest. Protein, this substance can cause poor gastrointestinal motility and cause constipation in the body.

3. Affect the body's absorption of iron: Because tea contains tannic acid, and this substance will combine with iron after entering the body, it will have an impact on the body's absorption of iron, which will greatly affect the body's absorption of iron. Most people who drink tea for a long time will develop iron deficiency anemia.
