喝隔夜茶（Drink overnight tea）

喝隔夜茶（Drink overnight tea） 喝隔夜茶(Drink overnight tea) Why is it so bad to drink overnight tea? Say so, do not know what the reason is. If I put the tea down, the tea leaves, over hot water, brew again, can not drink? Most drink a few days? What are? Said 4 hours after a cold to cancer material, according to have? Why? First of all, it is difficult to distinguish between the concept of overnight tea. Morning and afternoon tea bubble drink is very common, the night bubble tea, get up early in the morning after drinking tea, changes occur in the not larger than in daytime, I had to say, what is different, but the high daytime temperatures, changes may be more tea. Secondly, tea placed for a long time, the most important change is the further oxidation of tea polyphenols, color deepened. A cup of clear green tea, especially when placed in a higher temperature, loses its green color and increases its yellowness. This is the tea polyphenols in the oxidation of the formation of Huang Hong, red brown oxidation products, mainly theaflavins, tea red pigment, tea brown pigment and so on. These products are non-toxic and will not cause harm to humans. There has been speculation that tea and let the night, will produce nitrosamines carcinogens. This should be affirmed in tea even with nitrosamines, is not worth mentioning, many of our daily consumption of food, such as bread, vegetables, pickles, salted fish, bacon all contain nitrosamines, and the amount of water a lot of tea. But I don't see everyone eating dinner anymore. Nitrosamine content per kilogram of meat products in 4 to 50 micrograms, is not terrible, in fact, no, because the human body itself has the function of volatile nitrosamines. Besides, nitrosamines per kg body weight to achieve the absorption of 100 ~ 2000 mg can be carcinogenic, and taking large doses of persistent perennial the. The normal amount of normal food intake does not produce such great harm, and the quantity of tea is insignificant compared to the quantity of food consumed. Therefore, the fear of drinking tea will bring nitrosamines carcinogenic harm, there is no reason. In addition, tea contains a wealth of polyphenols and vitamin C, are nitrosamines natural inhibitors. As a result, tea can also eliminate the dangers of other foods containing nitrosamines. Tea is rich in tea polyphenols, by scavenging oxygen free radicals, inhibit lipid peroxidation, the inhibition of other carcinogens is also quite obvious. Vitamin C and vitamin E in tea also have the effect of supporting cancer. Overnight tea because time is too long, most of the vitamins have been lost, and the tea in the protein, sugar and other bacteria and fungi will become the breeding of nutrients, so people usually think that overnight tea can not drink. In fact, there is no deterioration of overnight tea, not only to drink, but also the following health care role: Cancer fighting and antioxidant: tea will be placed over a long time to become reddish brown, this is due to the oxidation of tea polyphenols into red brown tea pigment. Studies have shown that tea polyphenols and tea pigments have a strong anti-cancer and antioxidant effects, although the content of vitamin C in overnight tea is greatly reduced, but it still has a disease resistance. Hemostasis: overnight tea contains rich acid, which can prevent capillary bleeding. If suffering from stomatitis, tongue carbuncle, eczema, bleeding gums, are available overnight tea mouthwash treatment. The pus, bleeding in the skin can also use the bath. Bright eyesight: the tea polyphenols in the overnight tea have antibacterial and anti-inflammatory effects. If the eyes appear red silk, you can wash them several times a day with overnight tea.

Sun: skin sunburn by the sun, you can use a towel dipped in overnight tea, gently wipe. Because tannic acid has a astringent effect on the skin, flavonoids in tea also have an anti radiation effect. Fishy greasy food: overnight tea and strong smell and greasy effect except in addition to eat crabs, to wash refreshing. The use of overnight tea, should be in the same degree as bad (metamorphic). The summer temperature is high, easy to rancidity tea taste, if used more than 24 hours, it is best not to drink, otherwise it will cause diarrhea. Overnight tea: especially the taste of tea, but you can't even out of taste, and most of the breeding and breeding a large number of bacteria. Tea contains a large amount of protein, most of which are insoluble in hot water, and remain in the tea leaves. When the water temperature is high, the protein on the tea will rot. After one night, there will be an enzyme producing bacteria, A large amount of tannin is also retained in the tea. After oxidation, these tannins can turn into a strong, stimulating oxide that can irritate the stomach and cause inflammation. Therefore, overnight tea is not suitable for drinking. People usually don't think overnight tea can be drunk. When tea is placed for a long time, it turns to reddish brown.
