Can die if drinking green tea indiscriminately

Green tea is a healthy drink, however the "healing" properties in this drink can become a "killer" if you drink it indiscriminately.

Drinking green tea after or during meals, drinking green tea with medicine, drinking green tea that is too strong or too much… are all ways you are inviting illness into your body. Drinking green tea indiscriminately like that can cause you to suffer from some of the following dangerous diseases:

Malnutrition

A bad habit that many people have is drinking green tea right after a meal, or even during a meal. Drinking green tea this way will prevent the body from absorbing the nutrients in its daily diet, especially folic acid, protein, iron, etc.

According to nutritionists, green tea contains tannic acid. If you drink green tea during or immediately after a meal, the protein in the food will become hard and the body cannot absorb it. Tannic acid and caffeine in green tea also inhibit the absorption of iron (folic acid).

Therefore, if you regularly drink green tea in this way, even though you eat well, your body can still lack nutrients, leading to physical weakness. In particular, the risk of anemia is very likely to occur, especially for pregnant and lactating women.

To avoid the risk of malnutrition and to maximize the special benefits of green tea for the body, you should only drink it 30 minutes after a meal, and at least wait 15 minutes after a meal before drinking.

Because of the special properties that inhibit the body's absorption of iron in green tea, for those who are addicted to this drink, it is best to eat foods rich in iron and vitamin C regularly during the day.

Drinking green tea indiscriminately right after meals will cause anemia.

Hand tremors and some dangerous diseases

For people with normal health, drinking tea is a healthy habit if used in moderation. However, drinking too much or too strong tea can make the body sick, even leading to death.

The reason is that the caffeine content in green tea is quite high (only less than that of coffee). If you drink too much (over 5 cups/day), or too strong, it can cause tremors, especially hand tremors.

In addition, the high caffeine content in green tea can treat many diseases such as: diabetes, diarrhea, constipation, insomnia, irritable bowel syndrome (IBS), increased heart rate...

Therefore, healthy people are also advised to drink only 3-4 cups/day. Pregnant and lactating women should only drink 1 cup/day. Drinking more than 1 cup/day can increase the risk of miscarriage.

Each 240ml cup of green tea contains about 47mg of caffeine, of course the caffeine content will vary depending on how strong or weak the tea is brewed. Using green tea in very high doses, about 10 - 14g, can reduce the absorption of iron from food and can even cause death (according to the National Institutes of Health).

Stomach ulcer

It is quite common to like to drink tea that is too hot, and to blow on it while drinking it to make it taste better. However, according to experts, this way of drinking can cause stomach problems. When drinking green tea that is too hot (over 600C), it will damage the inner wall of the stomach, leading to stomach ulcers.

Although a good pot of green tea must be brewed from boiling water, the ideal temperature for drinking green tea is around 45 - 50 degrees Celsius.

Dizziness

This is just a temporary symptom but it makes your body extremely uncomfortable. The reason you feel dizzy and nauseous (also known as green tea intoxication) is because you drink green tea on an empty stomach.

Drinking green tea on an empty stomach will cause the astringent substances in the tea to enter the lungs and cool the spleen and stomach. When the spleen and stomach are cold, the body will show signs of “tea intoxication” as above.

Digestive disorders

Drinking green tea on an empty stomach can also cause indigestion. Because green tea has the ability to stimulate the stomach to secrete more acid (sour). This sour taste will make you lose your appetite, your body will absorb food less well and can cause indigestion.

Increased heart rate and blood pressure

According to MedlinePlus, dangerous drug interactions have been reported when green tea is combined with stimulants such as narcotics or ephedrine. Stimulants work together with the caffeine in green tea to increase heart rate and blood pressure.

Drinking green tea while eating oranges can also increase heart rate and blood pressure.

Brain hemorrhage can lead to death if green tea is not drunk properly.

Cerebral hemorrhage

Drinking green tea while taking medications containing phenylpropanolamine, an ingredient in weight loss products and cold medications, can cause a spike in blood pressure and increase the risk of a brain hemorrhage.

Because green tea puts stress on the liver, it is dangerous to take green tea along with medications that have unwanted liver-damaging effects such as acetaminophen, phenytoin, methotrexate, and others.

Green tea can slow blood clotting, so it should not be taken in combination with anticoagulants such as warfarin, ibuprofen or aspirin. Similarly, patients who are scheduled for surgery should stop drinking tea before undergoing surgery to prevent bleeding.

Any liquid other than water is not recommended for taking medication, including green tea. If you take medication with green tea or drink green tea at the same time as taking medication, it may cause hormonal and antibiotic stimulation in the body. This not only reduces the effectiveness of the medication but can also be life-threatening.
