Can you drink tea overnight? Please, thank you

From the perspective of nutrition and hygiene, if the tea soup is left for a long time, the vitamin C and other nutrients in the tea soup will be reduced due to gradual oxidation, and the taste will become bland. In addition, especially in summer, when placed at high temperatures for a long time, the proteins and sugars in the tea are the medium for bacteria and molds, which are easy to breed molds and bacteria, resulting in the deterioration and corruption of the tea soup.

1. It is recommended not to drink tea overnight.

2. Tea contains a large amount of catechins, creatine, folic acid, pantothenic acid, etc., these substances can produce a variety of biological activities on the human body, first of all, there is a certain protective effect on the cardiovascular system, tea polyphenols in tea can improve the microcirculation of the human body, have a certain role in promoting fat metabolism, and can reduce the occurrence of hyperlipidemia.

3. However, it is not recommended to drink tea overnight, and tea leaves will breed a lot of bacteria overnight. Moreover, the nutrients in tea have long been lost, and contain a lot of oxides, which may affect the health of the body and intestines, and then cause people to have diarrhea.

1. Tea leaves should not be drunk overnight;

2. The tea polyphenols in the tea soup have been oxidized after being exposed to the air for too long, and the vitamins have also been destroyed, leaving behind mostly harmful substances that are difficult to dissolve. Tea soup is exposed to the air, easy to be infected by microorganisms, tea contains proteins and sugars, is the nourishment of bacteria and mold, left for too long, the tea will deteriorate, if in the summer, may also produce a rancid taste.

3. Overnight tea may have a certain degree of impact on the body, for health reasons, it is better to drink tea with brewing.

1. Tea can be drunk overnight, but it is best not to drink it.

2. After the tea is left overnight, the nutrients are destroyed, and bacteria are easy to breed, resulting in the deterioration of nutrients such as proteins. After the tea is spoiled and drunk, it may hinder the absorption and digestion of nutrients by the human body, and may also cause gastrointestinal discomfort, and in severe cases, cause diarrhea and other adverse symptoms. Therefore, it is better to drink tea or brew it freshly, and it is best not to drink tea overnight, so as not to cause harm to the body.

1. Tea leaves that have been left overnight cannot be drunk.

2. Overnight tea can theoretically be drunk without deterioration, but overnight tea soaking for a long time may lose more vitamins, and the tea taste will become lighter, and it is worthless to continue brewing. In addition, after the tea is left overnight, due to the long-term exposure in the air, spoilage bacteria and other bacteria are easy to breed, making the tea easy to spoil and rancid.

3. On the other hand, if the overnight tea is not drunk for a long time, it is easy to be polluted by dust and mosquitoes, and bacteria and molds can multiply, which is easy to cause adverse effects on the body and is easy to deteriorate and cause diarrhea.

Hello, overnight tea water is not allowed to drink.

Due to the long time of overnight tea water, a large number of vitamins, amino acids and other components may have been lost, and it cannot play the original effect of tea water after drinking.

The proteins and sugars contained in tea have become nutrients for the reproduction of bacteria and molds, and tea water is prone to rancidity and taste, and diarrhea or abdominal pain may occur after drinking.

The tea polyphenols contained in the overnight tea water are basically oxidized, and after the oxidized substances enter the body, they may induce inflammation, ulcers, necrosis and other phenomena in the kidneys, liver, stomach and other organs.

The concept of overnight tea is difficult to distinguish Tea brewed in the morning is very common to drink in the afternoon, tea brewed in the middle of the night, drunk after getting up early in the morning, the changes that occur in the tea will not be greater than during the day, if you have to say that there is any difference, but the temperature during the day is high, and the change in tea may be greater. What will happen to the tea after it has been left for a long time Studies have shown that the most important change is the further oxidation of tea polyphenols and the deepening of color. A cup of clear and turquoise tea, especially if left for a long time in high temperatures, will lose its green color and increase the degree of yellowness.

This is the oxidation product of the oxidation of tea polyphenols in tea to form yellow-red and reddish-brown, mainly theaflavin, thearubigin, theabrownin, etc. These products are non-toxic and do not cause harm to the human body. Therefore, overnight tea or tea that has been brewed for too long has no toxic effect as long as it has not deteriorated.

It's not that you can't drink tea overnight, but you can't drink tea for more than 12 hours. Because after more than 12 hours, many harmful bacteria will be generated in the tea, but it can be used to rinse the mouth, which can remove bad breath, clean teeth, and have a strong and protective effect on the gums. Applying it to the eyes can also eliminate dark circles, especially with overnight chrysanthemum tea.

This method should also be suitable for people, in fact, tea has more or less the effect of **, but for the personal physical quality is not the same, the absorption of tea is definitely different, Pu'er tea has a benefit, after artificial fermentation, so that the damage of theophylline to the stomach has been reduced a lot, and drinking Pu'er tea on an empty stomach can be **.

1. Overnight tea can be drunk as long as it has not deteriorated. "Overnight tea" refers to a tea soup that is brewed the day before and left overnight. After a long period of time in the tea soup, the main change is that the tea polyphenols contained in it are oxidized to gradually form yellow-red and red-brown oxidation products, resulting in the continuous deepening of the color of the tea soup.

2. If a cup of clear and turquoise tea soup is left for a long time, especially in the case of high temperature, it will lose its original green color, and the degree of yellow and red will continue to increase, and the clarity of the tea soup will also decrease, and it will become more and more turbid. However, these oxidation products are non-toxic and do not cause harm to the human body.

3. However, at the same time, it should also be recognized that due to the long time of tea soup, the protein, sugar and other substances in the tea soup are effective nutrients for the reproduction of bacteria and molds, therefore, there is the possibility of breeding harmful microorganisms in the tea soup when it is placed for a long time, which may lead to the deterioration of the tea soup.

4. Therefore, from the scientific point of view of drinking tea, it is still necessary to advocate brewing and drinking, and try to avoid drinking tea soup that has been placed for too long such as "overnight tea", so as to give full play to the value of tea and provide the best nutrition and health ingredients for people's health.
