How to drink tea is healthy?

How many cups of tea do you drink every day? As the saying goes, everything without beauty or evil is a disaster. Tea is good, but drinking too much is still bad for your health! Especially the healthy way of drinking tea, especially not advocating drinking strong tea! Under normal circumstances, 2-3 cups of light tea a day, female friends can also add dried flowers, lemon slices or kumquat according to their own preferences. The unique fragrance of dried flowers and plants can enrich the taste of tea, and lemon or kumquat is rich in vitamin C, which can improve the absorption rate of tea polyphenols. For friends who are sensitive to caffeine, it is best to drink tea before 10 in the morning to avoid affecting the quality of sleep at night. At the same time, drink some boiled water between tea drinks to prevent the diuretic effect of caffeine and let the human body exclude more water when drinking tea. How many times can a cup of tea be brewed? 85% of the beneficial components in tea will precipitate in the first soaking, and there is little left after the second and third soaking. So a cup of tea, soaked for 3-4 times, can be changed. At the same time, remind friends who have the habit of "washing tea" that what you pour out in the first cup is the essence of most of this cup of tea. It's a pity to discard the tea brewed for the first time. What is the best water for making tea? Lu Yu of Cha Sheng pointed out in Tea Classic: "Its water is used for mountains, rivers and wells". It can be seen that making tea and choosing water is very particular. The purer the water quality, the better the color and fragrance of tea can be brought into play. Therefore, pure water and high-quality mineral water are most suitable for making tea, and the aroma of the brewed tea soup is bright and pure. However, our tap water generally stays in the pipeline for a long time and contains more iron and chlorine. These "impurities" will affect the taste of tea soup and make it turbid. Install a purifier in tap water, and the filtered water can also get better tea-making effect. Do tea stains need to be cleaned regularly? It is widely rumored on the Internet that tea scale contains heavy metals, and irregular cleaning is extremely harmful to the health. Is the truth really as terrible as online rumors? First of all, we must understand how tea dirt is produced! Scaling is caused by the concentration, precipitation and oxidation of polyphenols and some metal elements (calcium, magnesium, lead, mercury, etc.) in tea. ) In the tea-making water, brown precipitate is formed and attached to the cup wall. These metal-containing deposits mainly come from drinking water for making tea rather than tea itself. So: (1) Even if you don't drink tea, as long as you drink tea water, you will still consume these metal substances; (2) As the water-insoluble precipitate has been formed and adsorbed on the wall of the teacup, it is naturally more difficult to absorb than the original water-soluble state. Therefore, tea scale is not as terrible as rumored on the Internet. However, tea stains are not beneficial after all, and sticking to the cup wall will also affect the appearance. Soak the cup in baking soda and clean it with a soft brush. It is easy to wash off. When choosing tea, choosing pure water can also reduce the generation of tea scale. Overnight tea is poisonous. Did you drink it? Can't you drink? People's anxiety about overnight tea stems from their anxiety about overnight dishes. Because tea belongs to leaves and has a high nitrate content, many people are worried that nitrate in tea will be transformed into nitrite under the action of bacteria overnight, which is harmful to human health. We use about 2g of tea to make tea, which is converted into fresh leaves 10g. According to the maximum allowable nitrate content of pollution-free vegetables-leafy vegetables, the nitrate content of a cup of tea is 30mg. Even if all of them were converted into nitrite, they did not reach the toxic dose (200mg). What's more, the above calculation is based on the maximum amount. The nitrate content in tea is far from as high as 3000mg/kg, and some nitrate is indeed converted into nitrite. It may be that tea itself has antibacterial effect, which leads to poor conversion rate. It has been found in domestic experiments that the nitrate concentration of green tea rises slowly at first, then rises linearly, and finally falls slowly at different storage times, and the change trend of nitrite concentration is unknown. So the nitrite content of a cup of overnight tea is not terrible! Who should not drink tea? Generally speaking, tea is suitable for most people. But here I have to remind patients with gastric ulcer and duodenal ulcer, anemic people and pregnant women to use strong tea with caution! Occasionally, you can drink some light tea, and friends with peptic ulcer can mix some milk when drinking tea, which can reduce the irritation of tea to the stomach. How to choose tea We are not professional tea people. It is difficult to distinguish the quality of tea with some skills that require special training. In fact, it is important to choose legal tea products and avoid buying unknown bulk tea. If conditions permit, it is best to choose organic tea, so much the better! Several kinds of "good tea ceremony" suitable for drinking in four seasons-jasmine green tea: just sprinkle a few jasmine flowers in green tea. Scented tea is warm and has a soft smell. Paired with green tea, it can not only neutralize the "green" taste of green tea, but also inspire people and eliminate spring sleep. Very suitable for office white-collar workers and mental workers. Summer-mint green tea: buy a small pot of mint and put it at home. Every time you drink tea, pick a mint leaf and put it in. The refreshing mint will fall into your mouth and stomach with the fragrance of green tea. Bring a little coolness to the summer heat, and slowly expand from the stomach! Autumn-kumquat green tea: Vitamin C can promote the absorption of tea polyphenols. Kumquat is a kind of fruit rich in vitamin C, which is richer than lemon. Putting half a kumquat in tea can not only improve the health care effect of tea, but also increase the taste of tea. Winter-ginger juice black tea: both ginger and black tea have the effect of generating heat and warming the stomach. In winter, the two are combined to make a warm drink, which warms the stomach, warms the heart and warms the body!
