In recent years, matcha drinks have become popular all over the world and are regarded as "anti-oxidant sacred products". A young American woman was fascinated by matcha and ended up in the hospital. She shared cases on social websites, reminding that even healthy foods may bring unexpected risks if they ignore their own quality and drinking methods. According to

Newsweek, Lynn Shazeen, 28, of Maryland, United States, began to take on matcha in May this year and quickly fell in love with this drink. In addition to liking its taste, she also appreciates that matcha is rich in antioxidants, can promote health, and has a lower caffeine content than coffee. She usually drinks matcha twice a week to get iron.

Shasin usually uses various health tracking tools to record his physical condition. In July, she suddenly realized that her body was not in acclimatized, always tired, accompanied by skin development and cold fear. When the symptoms continued, she immediately went to the hospital for a health check.

The blood test result shocked her. The cause was that she loved to drink Matcha. She had a chronic blood loss problem, and Matcha made her blood loss serious. She later received a drop-to-dip treatment for iron and still needs to take a vitamin C-dip every day.

After it was found that the iron quality value had dropped sharply, Shaxin completely stopped matcha and drank other tea drinks, giving his body a period of time. Now his body condition has improved significantly. Shaxin said that he knew matcha would have an impact, so he was self-disciplined to drink it only once or twice a week, but he didn't expect that it would still be too much.

Shasin shared her experience on TikTok account, which caused great revelation. She was very excited to educate the public and raise her awareness, but she emphasized that she was not going to quit matcha altogether, but reminded matcha not to be at all risk: "Although matcha has evil my blood, I still want to remind girls with blood that they can still enjoy matcha, as long as they are careful."

Matcha can block iron absorption. The doctor recommends that you use it differently for meals

According to the Clifflan Medical Center in the United States, blood is a blood disease that can cause insufficient healthy red blood cells and the inability to deliver oxygen throughout the body. The most obvious symptoms are fatigue, and others include chest pain, head pain, susceptibility to infection, headache, shortness of breath and palpitations. Some cases of puerpers are derived from the history of the disease, while others are related to lifestyle, such as iron-deficient puerpers.

Home medical specialist Dr. Parth Bhavsar said that matcha may play the role of "iron quality stompist" to prevent iron quality from entering the bloodstream. If you drink a lot at a meal, the impact will be particularly significant.

He explained: "Matcha is a powdery green tea, which contains polyphenols. This substance will combine with iron in the kidneys and prevent absorption. If you drink matcha during meals, it will further reduce iron absorption. The simplest solution is to arrange matcha for two meals, or use vitamin C with plant-based foods rich in iron to increase absorption and reduce the adverse effects of matcha."
