2. The period when girls are not suitable for drinking tea
1, when the physiological period comes
At this time, menstrual blood will consume a lot of iron in the body. Therefore, female friends should add more vegetables and fruits rich in iron, such as spinach, grapes and apples.
However, if you are used to drinking tea when you are full at this time, this tea contains as much as 50% tannic acid, which will hinder the absorption of iron by our intestinal mucosa and greatly reduce the absorption of iron, so it is easy to precipitate with iron in chyme or iron stones in blood tonic drugs in the intestine.
2. Pregnant women are pregnant.
Generally, the concentration of caffeine in strong tea is as high as 10%, which will increase the number and frequency of urine and heartbeat of pregnant women, and increase the load of heart and kidney of pregnant women, which is more likely to lead to pregnancy poisoning, so it is better to drink less tea.
3. Before the pregnant woman is about to give birth
If you drink too much strong tea before delivery, the caffeine in the tea will have an exciting effect and cause insomnia. If pregnant women don't get enough sleep before delivery, it may lead to exhaustion during delivery and even dystocia, which is serious.
4. Mothers who want to breastfeed themselves just after giving birth
Because if you drink a lot of tea during this period, the high concentration of tannic acid in tea will be absorbed by the mucosa, which will affect the blood circulation of the breast and inhibit the secretion of milk, resulting in insufficient milk secretion.
After the mother drinks the tea, the caffeine in the tea can penetrate into the milk and indirectly affect the baby, which is not good for the baby's health.
5. Women in menopause

If you drink too much tea, these symptoms will be aggravated, so if people who like tea are at these special stages, it is best to stop, so as not to damage their health!
