“Seven things to open the door, firewood, rice, oil, salt, sauce and vinegar tea.” Many health experts love to drink tea. Tea can digest food, relieve tiredness, diuresis, and improve eyesight. There are many benefits.
But if you drink it incorrectly, this cup of tea may also become “disease tea” and “deadly tea”!
These two kinds of tea damage the kidneys, hurt the stomach and cause cancer!
Loving strong tea, it hurts the kidneys and stomach and the whole body
Some “old tea drinkers” like to put a lot of tea leaves when they make tea, and they always feel that this is enough. Many people also drink a cup of strong tea to refresh themselves when they are working and studying.
However, strong tea can harm the body in more than one or two places.
Kidney damage
Tea contains a lot of oxalic acid, which can easily lead to kidney stones. It is also high in fluorine, which accumulates in the kidneys and can damage it.
Stomach injury
A large amount of caffeine and theophylline in strong tea will stimulate the secretion of gastric acid. Regular drinking can easily damage the gastric mucosa, and even cause gastritis and gastric ulcers.
Destroys sleep, damages blood vessels
Caffeine can excite the brain, cause insomnia, and also make the heart beat faster and blood flow faster, resulting in arrhythmia, tachycardia, and palpitations.
Destroyed bones
Drinking strong tea regularly will not only inhibit the absorption of calcium, but also accelerate the excretion of calcium, resulting in the loss of bone calcium and osteoporosis.
In addition to calcium, strong tea can also hinder the body’s absorption of iron, cause iron deficiency anemia, and easily cause the loss of other nutrients.
In short, drinking it once or twice is fine, but drinking strong tea regularly will cause these damages to accumulate.
Especially patients with gastric ulcers, cardiovascular and cerebrovascular diseases, hyperthyroidism, kidney stones, insomnia, and women who are menstruating, pregnant, and breastfeeding should not drink it.
How about strong tea? It is generally recommended to put 3 grams of tea leaves per 150 ml of water. If this amount is greatly exceeded, it is strong tea. If you feel that you are not sure, you can judge this way: strong tea is astringent to drink, the color is thick and a little cloudy, and after the tea is cool, there will be a layer of tea oil floating on it.
Drinking hot tea often, esophageal cancer is eyeing you
How hot does this “hot” refer to? The answer is: Over 65℃.
The International Agency for Research on Cancer has classified hot drinks above 65°C as Class 2A carcinogens, and boiled water, tea, coffee and soup above this temperature are all included in this list.
Many Hokkien and Chaoshan people drink kung fu tea while it’s hot. The high incidence of esophageal cancer in these areas may be related to this habit.
The mucous membrane on the surface of the esophagus is delicate and fragile, and it can be scalded when it exceeds 65°C. Some people like to drink freshly brewed tea, and the temperature even reaches 80°C.
Occasional burns can also repair themselves, but if they are too frequent, abnormal “atypical” cells will increase and eventually become cancerous.
Even if there is no cancer, the oral cavity, esophagus, stomach and other parts will inevitably be damaged.
Tips: Just brewed tea, be sure to let it sit, let it cool and drink it, sip it with your lips, and it doesn’t feel hot.
