“The more tea leaves we put, the more purines penetrate into the drink,” Arzamastsev specified.
The doctor emphasized that people with gout can only afford very weakly brewed tea, or they should do without it.
In addition, the doctor added, , insomnia, acute diseases of the stomach.
Arzamastsev recalled that tea is a source of caffeine – high vines of this substance can affect blood pressure fluctuations, which are associated with extremely unpleasant symptoms. In case of gastric disorders, drinking strongly brewed tea can exacerbate painful conditions, in healthy people it can cause heartburn due to irritation of the digestive tract mucosa. Those who are prone to heartburn should drink tea with caution.
