Old man Jiang loves tea very much, collected all kinds of tea and put it at home, one day he took out a tea cake, which looked a little strange, but Old Man Jiang didn't think much about it, so he directly boiled water and brewed this tea.
Not long after drinking, he felt a little sick to his stomach and went straight to the clinic downstairs.
The doctor asked him what he ate and what he drank, and the old man replied that he had drunk a cup of tea, and the tea cake had been for so long.
The doctor immediately reminded him: "There are several types of tea, you must not drink it, some of them are more harmful to the kidneys than tobacco and alcohol!" ”
Why does Old Man Jiang have a stomachache?
Old Man Jiang was taken aback when he heard this, what kind of tea will hurt his kidneys more than tobacco and alcohol? This is alarmist.
The doctor explained to Mr. Zhang in detail: "Did you make Pu'er tea yesterday to drink?" That tea cake has been sitting for a long time. ”
Old Man Jiang said, "Yes, how do you know? Are you monitoring in my house? ”
The doctor laughed: "I didn't set up a monitor at your house, because you said that you had a stomach ache after drinking tea, and I guessed that it was Pu'er tea." ”
Pu'er tea has to go through a long period of multi-strain fermentation, which constitutes the fragrance of Pu'er tea, this tea has a certain amount of mold, and we are returning to Nantian here, and the tea will become moldy if it is not stored properly.
"You must not have looked carefully, the tea may have been moldy, this kind of moldy tea is best not to drink, there may be mold in it, some may be poisonous, of course there may be stomach pain after drinking, and it may also hurt the kidneys."
Old man Jiang said: "Why does it hurt your kidneys? ”
The doctor smiled: "The kidneys and liver will both detoxify, and if you drink something with mold, it will naturally hurt the liver and kidneys." ”
Old Man Jiang said: "Then apart from moldy tea cakes, don't make tea and drink, what kind of tea can't be drunk?"
What kind of tea hurts the kidneys? Don't drink it for the elderly!
The doctor said earnestly, "There are several kinds of tea that we recommend not drinking. ”
1. Strong tea
The content of theophylline, oxalic acid and other substances in strong tea will be more than that of weak tea.
Long-term consumption of strong tea in large quantities in the elderly may increase the excretion burden of the kidneys, especially the elderly with kidney problems can not drink it.
2. Moldy tea
Mouldy tea leaves are caused by improper storage and mold growth after being damp.
These molds not only destroy the original nutrients of tea, but also may produce toxins that are harmful to the human body, and long-term intake will increase the risk of disease.
Older people have relatively weak immunity and are more susceptible to toxins, so you should never drink moldy tea.
3. Drink tea on an empty stomach
Drinking tea on an empty stomach is more irritating to the stomach.
The theophylline in tea can stimulate gastric acid secretion, and drinking it on an empty stomach is easy to damage the gastric mucosa, causing stomach pain, gastritis and other symptoms.
Many elderly people do not have a good stomach health, so try to eat something before drinking tea.
The doctor added, "I know you like to drink green tea, uncle. But uncle, you belong to a cold physique, it is better to drink less green tea and more black tea. ”
"I see that you usually drink tea, and it is recommended to put less salt, chicken essence, and oyster sauce when cooking, because the kidneys have a greater burden when metabolizing tea, and if you eat more salt, then the burden will be greater."
"Don't sit often, walk around more, it's good for the metabolism of the kidneys."
brief summary
Tea is good, but not all teas can be drunk.
Older people should remember that strong tea should be drunk sparingly, and moldy tea should not be drunk. Usually, when making tea, you should see if there is mold on the tea cake. Try not to drink tea on an empty stomach.
The elderly can drink tea according to their own physique, if the stomach is hot, it is recommended to drink green tea; If you have a cold stomach, it is recommended to drink oolong tea and black tea.
