Women should not drink green tea during menstruation

For women during menstruation, drinking green tea is not only not good for health, but may also cause certain troubles to the body.

Women face a large amount of blood loss during menstruation, and iron, an important element for the body to synthesize hemoglobin, is also lost along with the blood. In addition to the body's iron loss, women lose an additional 18 to 21 mg of iron during each menstrual period. Therefore, it is recommended that women supplement more iron-rich foods at this time, such as black fungus, pork liver, etc., to avoid iron deficiency anemia.

However, these efforts will be wasted if you drink green tea during your menstrual period. Because green tea contains more tannic acid, it will combine with the iron molecules in food to form a large amount of precipitate, which hinders the absorption of iron molecules by the intestinal mucosa. The stronger the green tea, the greater the inhibitory effect on iron absorption, especially when drinking tea after a meal. Therefore, women and people with anemia should drink less strong tea even in normal times.

Secondly, women often experience constipation during their menstrual period. This is related to the secretion of progesterone. The higher amount of tannic acid in green tea can also aggravate constipation symptoms because tannic acid has an astringent effect that can slow down intestinal motility and cause stool to remain in the intestines.

Third, during menstruation, women often experience varying degrees of mental tension, headaches, breast pain, and other reactions due to changes in neuroendocrine regulation functions. To avoid these reactions, you should control your emotions and not let yourself become overly excited. However, substances such as caffeine and theobromine in tea have a stimulating effect and can aggravate menstrual reactions such as dysmenorrhea, headaches, and back pain.
