Drinking strong tea and coffee refreshes 20-year-old girls with anemia

Coffee and strong tea is a refreshing recipe for many people.

However, during the final exam season, a 20-year-old female college student became lethargic.

What happened?

"as soon as I walked down the stairs, I was out of breath and felt lethargic all day." The age of 20 should be the most vibrant and beautiful age. On the other hand, Dan Dan, a 20-year-old sophomore, felt that she was always listless and could not lift her spirits when she did anything.

Dan Dan has been preparing for the TOEFL exam nervously these days. "is it possible that you are sick if you are always out of shape like this?" She decided to go to the hospital for an examination.

A check for hemoglobin, the doctor and she were startled: Dan Dan's hemoglobin is only 5 grams, while the normal person's hemoglobin is 11 grams, severe anemia.

"before the examination is normal, how can you be anemic?" Dan Dan was puzzled.

Zhou Ping, director of the department of internal medicine at Hangzhou Hospital of traditional Chinese Medicine, inquired in detail about Dan Dan's daily habits and found that in the past six months, Dan Dan had memorized words to do exercises from morning to evening, and in order to refresh himself, he drank five or six cups of coffee and strong tea every day. Coffee and tea are the "culprits".

Excessive drinking of coffee and tea may lead to iron deficiency anemia. This is because tannic acid in tea and polyphenols in coffee can form insoluble salts with iron and inhibit iron absorption; drinking strong tea after meals is even more harmful, because iron, vitamins and other substances necessary for the human body are usually ingested in the daily diet, and the food is still in the stomach after a good meal, when drinking strong tea, tannic acid is easier to combine with iron and hinder the absorption of iron.

Zhou Ping said that if you suffer from iron deficiency anemia, you should first pay attention to your diet and balance your intake of iron-rich foods such as animal liver, egg yolk and cereals. If the iron intake in the diet is insufficient or the iron deficiency is serious, iron supplements should be taken immediately. (reporter Lin Dan, correspondent Xu Youjia)
