Today, let's simply understand these points about tea drinking. How should we drink tea healthily? The following content is for reference only:

1. How much tea should a normal person drink in a day?

The amount of tea one drinks depends on factors such as their tea-drinking habits, age, health condition, living environment, and local customs. Generally, healthy adults who are accustomed to drinking tea can consume about 12 grams of tea per day, divided into 3-4 brews, which is appropriate. For those who do heavy physical labor, consume more food, or are in high-temperature environments and exposed to more harmful substances, drinking around 20 grams of tea per day is suitable. People who eat more greasy foods or smoke and drink alcohol heavily can also appropriately increase their tea intake. Pregnant women, children, people with neurasthenia, and those with tachycardia should reduce their tea consumption.

2. Why should you drink more tea after eating salted vegetables and cured meat products?

Salted vegetables like pickles and preserved vegetables, and cured meat products like preserved meats, cured hams, and sausages, often contain higher levels of nitrate. When secondary amines are present in food, nitrate and secondary amines can react chemically to produce nitrosamines, which are dangerous carcinogens that can easily cause cellular mutations leading to cancer. The catechins in tea have the ability to block the synthesis of nitrosamines. Therefore, after consuming salted vegetables and cured meat products, it is advisable to drink more high-grade green teas rich in catechins, which can inhibit the formation of carcinogens and enhance immune function, benefiting overall health.

3. Why should smokers drink more tea?

From a health perspective, quitting smoking is imperative. However, for those who cannot quit immediately, drinking tea is an excellent way to mitigate the harmful effects of smoking. The polyphenols and vitamin C in tea have detoxifying effects against the various harmful substances in cigarettes. Drinking tea while smoking helps continuously eliminate toxins through urination, which are then expelled from the body through feces. Smoking individuals who regularly drink tea primarily gain four benefits:

First, it reduces the risk of cancer induced by smoking. Second, it aids in reducing radiation exposure caused by smoking.

Third, it helps prevent cataracts triggered by smoking. Fourth, it replenishes vitamin C lost due to smoking.

4. Drink tea frequently in front of screens

Tea contains β-carotene, molybdenum, calcium, lipopolysaccharides, and tea polyphenols, which all help alleviate visual fatigue and protect against radiation.

The harm caused by screen emissions goes beyond just vision, affecting the nervous system, immunity, and cardiovascular health, although these effects may not be as directly observable as changes in vision. Drinking tea significantly helps mitigate the harm from screen emissions, most directly by increasing urination, allowing toxins to be expelled, thus “purifying” the body.

So, when watching TV or sitting in front of a computer, sipping a cup of clear tea is both enjoyable and health-promoting. Tea, a treasure in its entirety, should always be on hand and used regularly.

5. Why shouldn't tea be used to sober up from alcohol?

Alcohol accelerates blood circulation and dilates blood vessels, having a significant stimulating effect on the heart, causing an increased heartbeat. The Caffeine in tea also has a stimulating effect on the heart. When combined, this places a heavier burden on the heart.

When drinking tea after alcohol, the caffeine in tea quickly reaches the kidneys, causing diuresis. At this point, alcohol has been converted into acetaldehyde but not yet into acetic acid, carbon dioxide, or water, and is excreted through the kidneys. Since acetaldehyde has a strong stimulatory effect on the kidneys, this can be detrimental to health. Clearly, drinking tea after alcohol is not advisable. Instead, one can drink some vinegar, fruit juice, sugar water, or eat fruits.

6. How should patients with gastric problems drink tea?

There are many types of gastric problems, including superficial gastritis, atrophic gastritis, gastric ulcers, and gastric bleeding. Patients with gastric problems generally should not drink tea while taking medication. Two hours after taking medication, they can drink light tea, sugared Black Tea, or milk black tea, which can help with inflammation and protect the gastric mucosa, aiding in ulcer healing. Drinking tea can also prevent the synthesis of N-nitroso compounds, preventing precancerous changes.

7. Which type of tea is more beneficial for health?

It is difficult to provide a simple answer to which type of tea is best for health. In other words, different types of tea have varying nutritional and medicinal components, making them suitable for people with different health conditions. For example, people with weaker constitutions can drink some black tea, adding sugar and milk, which increases energy and provides nutrition. Young people in their vigorous growth phase should drink Green Tea.

Women before and after menstruation and during menopause, who may experience irritability, can benefit from drinking scented tea, which has liver-soothing and qi-regulating effects.

People who are overweight and wish to lose weight can drink more Oolong tea and tuocha.

Those who regularly consume large amounts of beef and mutton can drink more brick tea and Compressed tea, which aids in the digestion of fatty foods.

Workers regularly exposed to toxic substances can choose green tea as a protective beverage. Intellectual workers, military personnel, drivers, athletes, singers, announcers, actors, etc., to improve mental agility, maintain clarity and fullness of mind, and enhance cognitive, judgment, and memory abilities, can drink green teas.

8. How many times should a cup of tea be brewed?

From a nutritional standpoint, 80% of the vitamin C and amino acids in tea are extracted in the first brew, with over 95% extracted by the second brew. Other effective components, such as tea polyphenols and caffeine, are mostly extracted in the first brew, with three brews typically achieving almost complete extraction. It can be seen that for most red, green, and scented teas, brewing three times is usually sufficient. Oolong tea, due to the larger quantity of leaves used, can be brewed more times. Bagged tea made from black tea, being easy to extract, is generally suitable for a single brewing.
