Winter overnight tea is OK. Overnight tea has lost most of its vitamins due to too much time, and the proteins and sugars in the tea soup will become nutrients for bacteria and molds to multiply, and many people will think that overnight tea contains a lot of nitrite, so people usually think that overnight tea cannot be drunk.

Studies have shown that even overnight tea, as long as it is properly preserved, such as not affected by dust, the nitrite content in it should be far less than 1mg l, if there is really a danger to health, it must be a nitrite content of more than 100mg, there will be a risk of carcinogenicity.

Therefore, overnight tea without deterioration can be drunk, but in fact, the nutritional value of overnight tea and ordinary tea has not improved, before drinking, it is still necessary to pay attention to whether the overnight tea is stored properly, whether it has deteriorated and so on, and then decide whether to drink, then again, it is very cold in winter, and people with spleen and stomach deficiency are still recommended not to drink overnight tea.

You can drink overnight tea in winter, but it is best to drink it sparingly. There is no scientific basis for the claim that overnight tea causes cancer, even if the tea contains carcinogens nitrosamines, it is also a small amount, and nitrosamines need to be taken in large doses all year round to be carcinogenic, and drinking tea can obtain more tea polyphenols and vitamin C from tea, which can prevent the synthesis of nitrosamines in the body, soOvernight tea does not cause cancer.

However, when tea is exposed to the air for a long time, the vitamins, tea and other beneficial ingredients contained in it will be oxidized and reduced, losing its original nutritional value, and then producing all kinds of bacteria and molds, making the tea soup rancid and spoiled.

Therefore, it is best to brew and drink tea freshly, and try to drink less tea overnight.

[In the south] overnight tea in winter can not be drunk, there are many types of tea, but most of the tea needs to be boiled to drink, in order to taste the true taste of tea, but also conducive to the intake of influence, and overnight tea after placement, the degree of oxidation of the substances in the tea is higher, its flavor and taste are poor, the soup is dull, and secondly, after a long time of placement, the tea is easy to be infected with bacteria and particles, so the overnight tea in winter can not be drunk.

1. What is overnight tea?

The tea made today is "overnight" tomorrow, so the tea brewed at 8 o'clock in the morning is not overnight tea at 20 o'clock in the afternoon!

Secondly, after the overnight tea is placed for a long time, the substances in the tea have been basically oxidized, so that the tea leaves lose their original flavor and aroma, thus becoming boring and cold, and the soup will be greatly deepened or dull, so will you still drink such a tea soup, anyway, you will not drink it.

Therefore, no matter from the perspective of health and drinking, overnight tea cannot be drunk.

After a long period of storage, the tea polyphenols in the tea will gradually oxidize and turn red, and the color of the tea water will become darker. Even brewed green tea will turn yellow or red after being left for a long time. This is because after a long period of storage, the tea produces oxides in it, but these oxides are basically not harmful to the human body.

Therefore, we often say that overnight tea can not be drunk, this is because after a long time of storage, the secondary amines in the tea will be converted into nitrosamines, nitrosamines are carcinogenic to the human body.

Tea contains tea polyphenols, vitamins, catechins, amino acids and other components, antioxidant is one of the important effects of tea, tea exposed to the air for a long time, vitamin C, etc. are oxidized, tea polyphenols are oxidized into tea pigments, and the antioxidant effect will be weakened, especially green tea and white tea.

2. After the tea is left for a long time, tannic acid will be produced, and the tannic acid will be completely dissolved in the tea. After drinking in the morning, and then eating breakfast, tannic acid will interact with food to produce oxalic acid, and tannic acid and oxalic acid combine to cause chemical changes, which is easy to produce stones. At the same time, tannic acid also makes other nutrients more difficult to digest.

3. If the overnight tea is left for more than 24 hours, because the tea itself contains sugar and a small amount of protein, it will become moldy under suitable temperature and humidity conditions, produce bacteria and mold, and cause diarrhea. Therefore, tea that has been more than 24 hours old should not be drunk, especially in the summer when the temperature is high.

In fact, overnight tea that has not deteriorated can not only be drunk, but also has the following health effects: anti-cancer, anti-oxidation:

Tea will turn reddish-brown after being left for a long time, which is due to the oxidation of tea polyphenols into reddish-brown tea pigments. Studies have shown that tea polyphenols and tea pigments have strong anti-cancer and antioxidant effects, although the content of vitamin C in overnight tea is greatly reduced, but it still has anti-disease effects.
