What tea is more beneficial to health cannot be answered in a single sentence. In other words, different teas have varying nutritional and medicinal components, making them suitable for people with different physical conditions. For example, people with weaker constitutions can drink some black tea, adding sugar and milk to increase energy and supplement nutrition. Young people in their developmental years are better off drinking green tea. Women during menstruation, menopause, or experiencing emotional irritability can benefit from jasmine tea, which helps soothe the liver, relieve depression, regulate qi, and regulate menstruation. Those who are overweight or wish to lose weight can drink more oolong tea, tuo tea, and the like. People who consume a lot of beef and mutton throughout the year can drink more brick tea, cake tea, and other post-fermented compressed teas, which aid in digesting fatty foods. Workers often exposed to toxic or harmful substances can choose green tea as a labor protection beverage. Mental workers, military personnel, drivers, athletes, singers, broadcasters, actors, etc., can drink high-grade green teas, including various famous green teas, to improve mental agility, keep the mind clear and energetic, and enhance thinking, judgment, and memory.

If we compare the nutritional and medicinal content of various teas, high-grade green tea is superior to other tea types. For instance, the content of vitamin C, B1, B2, minerals such as phosphorus, potassium, zinc, and tea polyphenols is usually higher in high-grade green tea than in other teas. Therefore, from a nutritional and health perspective, drinking high-grade green tea is more conducive to health.

How much tea should be drunk per day?

The amount of tea consumed depends on factors such as drinking habits, age, health status, living environment, and customs. Generally, for healthy adults with regular tea-drinking habits, drinking about 12 grams of tea per day, brewed in 3-4 infusions, is suitable. For those with heavy physical labor, high energy consumption, and large food intake, especially those in high-temperature environments or frequently exposed to toxic substances, about 20 grams of tea per day is appropriate. People who consume a lot of greasy food or smoke and drink heavily can also increase their tea intake appropriately. Pregnant women, children, those with neurasthenia, and those with tachycardia should reduce their tea consumption.

Is drinking strong tea good?

Strong tea refers to tea brewed with an excessive amount of leaves (more than the usual 3-4 grams per cup). Strong tea is unsuitable for many people. For example, drinking strong tea at night can easily cause insomnia. It is also not recommended for those with heart disease (tachycardia), gastric ulcers, neurasthenia, or weak, cold constitutions, as it may worsen symptoms. Drinking strong tea on an empty stomach can cause stomach discomfort, palpitations, nausea, or even "tea intoxication." To relieve tea intoxication, eating one or two candies and drinking some plain water can help. However, strong tea is not entirely without benefits. At certain concentrations, it can clear heat, detoxify, moisten the lungs, resolve phlegm, strengthen the heart, promote diuresis, sober up, and aid digestion. Therefore, for those with damp-heat conditions or those who smoke or drink excessively, strong tea can help clear heat and detoxify, and aid in sobering up. After eating large amounts of meat or greasy food, strong tea can help digest and remove grease. For mouth inflammation or sore throat, strong tea has anti-inflammatory and antibacterial effects.

Can overnight tea be drunk?

There was once a belief that overnight tea should not be drunk because it causes cancer, supposedly due to secondary amines that can convert into carcinogenic nitrosamines. This claim is unscientific. Secondary amines are widely present in many foods, especially preserved meats, with the highest content. For example, bread typically contains 2mg/kg of secondary amines. If bread is a staple, daily intake from bread is 1-1.5mg. The secondary amine intake from tea is only about 40% of that from bread, which is negligible. Moreover, secondary amines themselves are not carcinogenic; they require the presence of nitrates to form nitrosamines at a certain level to be carcinogenic. Drinking tea provides tea polyphenols and vitamin C, which effectively inhibit nitrosamine synthesis in the body and are natural inhibitors. Therefore, drinking overnight tea does not cause cancer.

However, from a nutritional and hygienic perspective, tea left exposed to air for a long time can breed spoilage microorganisms, causing it to sour and spoil. Additionally, nutrients like tea polyphenols and vitamin C oxidize and decrease over time. Therefore, although overnight tea is harmless, it is generally best to brew and drink it fresh.

Canned tea beverages on the market are made with added antioxidants and undergo strict sterilization, making them safe to drink like other cold beverages.

How many times should a cup of tea be brewed?

The number of infusions varies by tea type. In daily life, people often notice that very fine, high-grade teas are not very耐受泡 (resistant to multiple brews) and usually lose their flavor after two infusions. Ordinary black and green teas can typically be brewed 3-4 times. The耐泡度 (brewing tolerance) of tea is related to leaf tenderness, but more importantly, it depends on the integrity of the processed leaves.

The more finely processed the tea, the easier it is to extract the liquor. Coarser, whole-leaf teas extract more slowly. Regardless of the tea type, the first infusion extracts over 50% of the soluble solids. For ordinary teas, the second infusion extracts about 30%, the third about 10%, and the fourth only 1-3%. From a nutritional perspective, 80% of vitamin C and amino acids are extracted in the first infusion, and over 95% are extracted by the second. Other active components like tea polyphenols and caffeine are also mostly extracted in the first infusion, with nearly full extraction by the third infusion. Therefore, for ordinary black, green, and jasmine teas, three infusions are generally sufficient. Oolong tea, due to its larger leaf volume used per brew, can be infused more times. Bagged tea made from broken black tea is suitable for a single infusion due to its ease of extraction.

How to arrange drinking if you have multiple teas at home?

Some people drink different teas at different times of the day. In the early morning, they drink a light cup of high-grade green tea to refresh the mind and clear the head. In the morning, they drink a cup of jasmine tea, which is fragrant and pleasant, to improve work efficiency. In the afternoon, they drink a cup of black tea to relieve fatigue and stay alert. During a break in the afternoon, they might have a cup of milk black tea or a cup of high-grade green tea with some snacks and fruit to supplement nutrition. In the evening, they gather with friends or family, brew a pot of oolong tea, and chat while drinking, creating a unique atmosphere. If you are interested, you can also try this clever daily tea arrangement.

Why do some people add goji berries, American ginseng, white chrysanthemum, tangerine peel, mint, etc., to their tea?

What are the benefits of drinking more tea for those frequently exposed to radiation?

If you are a radiologist, a patient undergoing radiation therapy, or a researcher frequently exposed to radiation, a certain dose of radiation can be harmful to the human body, often causing a decrease in white blood cells and weakened immunity. Scientific research shows that components like tea polyphenols in tea can enhance the body's non-specific immune function and increase white blood cell counts. Therefore, drinking tea is an ideal and simple method for anti-radiation damage. It is certainly beneficial for those who work with radiation or are patients to drink more green tea before and after exposure. Although the radiation from watching TV is minimal, drinking a cup of tea while watching TV is also beneficial from a preventive perspective.

In most cases, it is not recommended to take medicine with tea, especially for certain iron supplements (such as ferrous sulfate, ferrous carbonate, ferric ammonium citrate), aluminum supplements (like aluminum hydroxide), and enzyme preparations (such as protease, amylase). These can combine with polyphenols in tea and form precipitates, affecting the medicine's efficacy. Some Chinese herbal medicines like ephedra, coptis, and uncaria should generally not be taken with tea. Additionally, tea contains caffeine, which has a stimulant effect. Therefore, it is not advisable to take sedatives, hypnotics, or cough suppressants with tea to avoid conflicts and reduced efficacy. It is generally believed that tea should not be drunk within 2 hours after taking medication.

However, when taking vitamins, stimulants, diuretics, lipid-lowering, blood sugar-lowering, or white blood cell-boosting medications, tea can generally be used to take the medicine. For example, after taking vitamin C with tea, the catechins in tea can help the absorption and accumulation of vitamin C in the body. Tea itself has stimulant, diuretic, lipid-lowering, blood sugar-lowering, and white blood cell-boosting effects, so drinking tea can enhance the efficacy of these medications.

Why should you drink more tea after eating pickled vegetables and cured meats?

Pickled vegetables like kimchi and salted vegetables, and cured meats like bacon, ham, and sausage, often contain higher levels of nitrates. In the presence of secondary amines, nitrates and secondary amines can undergo chemical reactions to produce nitrosamines, a dangerous carcinogen that can easily cause cell mutations and cancer. Catechin substances in tea have the effect of blocking nitrosamine synthesis. Therefore, after consuming pickled vegetables and cured meats, one should drink more high-grade green tea with high catechin content to inhibit the formation of carcinogens, enhance immune function, and benefit health.
