Drinking tea is an indispensable way of life for modern people. However, tea cannot be drunk casually. If you don’t pay attention to some methods of drinking tea, not only will it not bring any benefits, but it will also have adverse consequences for our health.
Let's take a look at what's so important about drinking tea!
1. Do not drink too much
Strong tea will increase the "excitability" of the human body excessively, which will adversely affect the cardiovascular system and nervous system. People with cardiovascular disease may experience tachycardia and arrhythmia after drinking strong tea, which is easy to cause repeated illness.
2. Do not drink before going to bed
This is especially important for early tea drinkers. After many people drink tea before going to bed, it will become very difficult to fall asleep and even seriously affect the mental state of the next day. People with neurasthenia or insomnia should pay special attention.
3. Do not drink before meals
Drinking a small amount of tea before meals or during meals is not a big problem, but if you drink a lot of tea or drink too strong tea, it will affect the absorption of many macroelements (such as calcium, etc.) and trace elements (such as iron, zinc, etc.).
It is important to note that when drinking milk or other dairy products, do not drink tea at the same time. Because theophylline and tannins in the tea will combine with calcium in dairy products to form calcium salts that are insoluble in water and excreted from the body, the nutritional value of dairy products is greatly reduced.
4. Don't drink after drinking
After drinking, the ethanol in the wine enters the blood through the gastrointestinal tract and is converted into acetaldehyde in the liver, which is then converted into acetic acid, and the acetic acid is decomposed into carbon dioxide and water for discharge. Drinking tea after drinking, theophylline in tea can quickly play a diuretic effect on the kidneys, thereby promoting the premature entry of acetaldehyde that has not been decomposed into the kidneys.
Acetaldehyde has a greater stimulating effect on the kidneys and will affect kidney function. Therefore, people who often drink strong tea after drinking are prone to kidney disease. Not only that, the ethanol in wine is very stimulating to the cardiovascular system, and the tea also has the effect of stimulating the heart. The combination of the two enhances the stimulation of the heart. Therefore, drinking tea after drinking alcohol in patients with heart disease is more harmful.
5. Do not drink new tea
The so-called new tea refers to tea leaves that have been picked for less than a month. Because these teas have not been placed for some time, some substances have adverse effects on health, such as polyphenols, alcohols, aldehydes, and other substances, and they have not been completely oxidized. , If you drink new tea for a long time, you may experience uncomfortable reactions such as diarrhea and abdominal distension.
The new tea will irritate the gastric mucosa, cause gastrointestinal discomfort, and even aggravate the condition. Therefore, from a nutritional point of view, the nutritional content of tea leaves that are too fresh may not be the best.
6. Avoid taking medicine with tea
Some people who love to drink tea will choose to use tea to deliver medicine, but they do not know that the tannin in tea can be combined with the medicine to precipitate, which will change the medicinal properties, hinder the absorption, and affect the efficacy of the medicine. Therefore, the medicine should be taken with boiled water. This is also known as the "tea antidote".
7. Do not drink tea overnight
Overnight tea is easy to be contaminated by pathogenic organisms because it is shelved for too long, and the complex components in the tea are also prone to change. Drinking overnight tea can lead to gastrointestinal diseases. When I was a child, I was always taught that "tea overnight, diarrhea" seems justified.
8. The four seasons are different
Drink scented tea in spring, China green tea in summer, green tea in autumn, and black tea in winter.
Drinking scented tea in spring can disperse the cold evil that has accumulated in the human body in winter, and promote the occurrence of yang qi in the human body.
China green tea is bitter and cold. It is better to drink China green tea in summer. It can clear away heat, relieve summer heat, detoxify, quench thirst and strengthen the heart.
Green tea is neither cold nor hot. Drinking green tea in autumn can eliminate the residual heat in the body and restore body fluids.
It is ideal to drink black tea in winter. Black tea is sweet and warm. It is rich in protein, which can help digestion, replenish the body, and make the human body strong.
9. Drink plenty of tea
Although tea contains a variety of vitamins and amino acids, it has a certain effect on clearing oil and relieving greasy, enhancing nerve excitement, digestion, and diuresis, but it is not that the more you drink, the better, and not everyone is suitable for drinking tea.
Generally speaking, it is appropriate to drink tea once or twice a day, with 2 to 3 grams of tea each time. People suffering from neurasthenia, insomnia, hyperthyroidism, tuberculosis, heart disease, stomach disease, and intestinal ulcer are not suitable for drinking tea, nor are lactating and pregnant women and infants.
