Why do I always drink cold tea? Why is cold tea hurtful?

Drinking herbal tea is not good, first, it is a personal habit. The reason for the formation of this habit is explained in conjunction with yourself.

Because when I was young, there was no running water in the countryside at home. I ate snow when I was in a hurry since I was a child. Or ice, that's how life was in the 80s.

Thus such a habit was formed. Drinking boiled or hot water always feels delicious. No cold water tastes good.

This is one of a kind.

Don't worry about drinking cold water for a long time. Thus pouring to the stomach cold. If the stomach is cold for a long time, the body will be weak, so the body will be more hot, and it will feel dry and hot whenever it is, so it likes to drink cold.

I'm not used to drinking hot. If this is not good, it is recommended to drink warm water. Or boiling water to make tea.

I've been drinking it for a few months now. Slowly, I got used to it. Drink it with jujube tea to regulate the body.

Now it's obvious that there is no big fire in the body, and there are no beans on the face, and I am drinking some mung bean soup when I have time. Exercise more. After a few months, my body will slowly adjust, but now I don't feel as good as before when I drink cold water :)

Drinking herbal tea is not good for your health, it is recommended that you get rid of this habit, you can pour hot water when you drink it, and you can pour it out if it is cold.

Is it an herbal tea drink or a cold tea? If it's a drink, drink less until it's nothing, but if it's a tea that's cold, don't drink it anymore, I don't know what's wrong, but all people are not good at drinking herbal tea, so it means that it's definitely not good, or don't drink it anymore.

Drinking herbal tea is not good, it's just your personal habit, it's better to get rid of it.

Cold tea has a stagnation of cold and phlegm accumulation on the body, especially for women with cold bodies, it is not suitable to drink cold tea. After brewing the tea, drink it in time, if you can't finish it, you should pour it out, and you can't put it in the refrigerator and drink it overnight.

In addition, you need to pay attention to the following two points when drinking tea:

Avoid drinking tea on an empty stomach. Drinking tea on an empty stomach will dilute gastric juice, reduce digestive function, and also cause "tea drunkenness", which is manifested as palpitation, dizziness, headache, fatigue, unsteady standing, etc. Do not drink tea immediately after eating.

It is not advisable to drink tea immediately after eating. Drinking tea immediately after meals will dilute gastric juice and affect food digestion, while the tannic acid in tea can make coagulant substances in food, increase the burden on the stomach, and affect the absorption of protein.

There was a legend that because overnight tea contains secondary amines, which can be converted into carcinogens nitrosamines, it is easy to get cancer if you drink it, so it is believed that "overnight tea cannot be drunk". In fact, there is no scientific basis for this claim. Because secondary amine itself is an unstable compound, it is widely found in many foods, especially in preserved products.

From the most common edible bread, it usually also contains 2 mg kg of secondary amines, such as bread as the staple food, the daily intake of secondary amines from bread up to 1 mg of milligrams. And people drink tea, and the secondary amine that enters from tea is only 1 40 of the staple bread, which is insignificant.

Road. Moreover, secondary amines themselves are not carcinogenic, but must be formed under the condition of nitrate, and only when a certain amount is reached can it have a carcinogenic effect. Drinking tea can obtain more tea polyphenols and vitamin C from tea, and experiments have proved that these two substances can effectively prevent the synthesis of nitrosamines in the human body and become natural nitrosamine inhibitors.

Therefore, drinking overnight tea will not cause cancer. However, from a nutritional and hygiene point of view, after the tea is brewed, over time, the vitamin C and other nutrients in the tea soup will be reduced due to gradual oxidation. In addition, the proteins and sugars in the tea are the medium of bacteria and molds, and the tea soup is not strictly sterilized, which is easy to breed mold and bacteria, resulting in the deterioration and corruption of the tea soup, and the spoiled tea soup is of course not suitable for drinking.

There are many people who have the habit of drinking cold tea, which can be drunk if it has not gone bad. But be careful, you can't leave a part of the tea soup for a long time before drinking, which is very unhygienic.

Cold tea beverages produced through strict sterilization measures are also drinkable. At present, most of the canned tea in the domestic and foreign markets belongs to this kind of cold tea, which is added with antioxidants and strictly sterilized, and the shelf life is more than half a year to more than one year, which is an ideal tourism and table drink.

There used to be a saying that because overnight tea contains secondary amines, which can be converted into carcinogens nitrosamines, it is easy to get cancer if you drink it, so it is believed that overnight tea cannot be drunk In fact, this statement has no scientific reason

Secondary amines are unstable compounds that are widely found in many foods, even the most ordinary bread contains The secondary amines that people ingest through drinking tea are insignificant and drinking tea can also obtain more tea polyphenols and vitamin C from it, both of which can prevent the synthesis of nitrosamines in the human body and become natural nitrosamine inhibitors So drinking overnight tea is not carcinogenic

Overnight tea has lost most of its vitamins due to a long time, and the proteins and sugars in the tea soup will become nutrients for bacteria and molds to multiply, so people usually think that overnight tea cannot be drunk. In fact, overnight tea that has not deteriorated can not only be drunk, but also has the following health benefits:

Anti-cancer and 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.

Hemostasis: Overnight tea is rich in acids, which can stop capillary bleeding. If you suffer from stomatitis, tongue carbuncles, eczema, bleeding gums, etc., you can rinse your mouth with overnight tea**. Sores and abscesses, **bleeding can also be bathed.

Eye-catching: The tea polyphenols in overnight tea have antibacterial and anti-inflammatory effects, and if red threads appear in the eyes, you can wash them with overnight tea several times a day.

Anti-itching: Wash your hair or wipe your body with warm overnight tea, the fluoride in the tea can quickly relieve itching, and can also prevent eczema.

Hair growth: Wash your hair with overnight tea, which also has the effect of hair growth and dandruff. If you think your eyebrows are thin, you can use a brush dipped in overnight tea every day to brush your eyebrows, and after a long time, your eyebrows will naturally become thick and shiny.

Solid teeth cleaning: After the fluoride in the tea and the enamel of the teeth are calcified, it will enhance the resistance to acidic substances and reduce the occurrence of tooth decay; Fluoride can also eliminate plaque, and it is best to rinse your mouth with tea two or three minutes after eating.

In addition to bad breath: tea contains essential oils, the smell is fragrant, before and after brushing teeth in the morning or after meals, gargle a few mouthfuls of overnight tea, which can make the breath fresh, and often rinse your mouth with tea can eliminate bad breath.

Sunscreen: **If you are sunburned by the sun, you can gently wipe it with a towel dipped in overnight tea. Because tannic acid has an astringent effect on **, the flavonoid compounds in tea also have an anti-radiation effect.

Remove smell and oiliness: Overnight tea also has a strong effect of removing fishy gas and oiliness, and it feels refreshing to wash your hands after eating shrimp and crabs.

When using overnight tea, it should be done in a way that does not spoil (spoils). The temperature is high in summer, and the tea is easy to rancidity, if it is left for more than 24 hours, it is best not to drink it, otherwise it will cause diarrhea.

The environment we live in is changing all the time, so with the continuous development of social economy and the continuous progress of science and technology. There are also a variety of new things in people's lives, including a variety of dietary products, but with the popularization of education, people are paying more and more attention to their physical health. For iced tea, many people are no stranger, because iced tea is very good in all aspects, so it has been welcomed by many people, so for this herbal tea, is it possible for many people to drink it?

For this problem, we should analyze it comprehensively and concretely according to specific things. <

First of all, the answer is definitely that not everyone can drink herbal tea, there are many periods and all kinds of special people who are not able to drink herbal tea. One of the most typical is the women's menstrual period, not suitable for drinking herbal tea, this is because women during menstruation, his blood loss is more, and think about the content of human nutrients is more, at this time, the human body's various skills in the room are relatively weak physical deviation, at this time, we should supplement a variety of nutrients. Including supplementing nutritious grapes, fruits, etc., and you can eat some foods with more content, more iron, such as peanuts and so on, but drinking herbal tea can not play such a role, and will also increase the corresponding burden on the digestive system and kidneys, and can also damage the spleen and stomach, and appear a variety of digestive symptoms, so this is very, unnecessary.

Another situation is that the mother during pregnancy is not suitable for drinking herbal tea, because drinking herbal tea will affect the heart rate and the number of heartbeats of pregnant women to a certain extent, and like the above, it will also increase the burden on the kidneys. So it means that pregnant mothers should not drink herbal tea. <

Of course not. Pregnant women should not drink it, because if pregnant women drink herbal tea, it will cause diarrhea, especially easy to cause uterine cold, and even miscarriage. People with diarrhea can't drink it, drinking herbal tea regularly will make diarrhea worse, and people with a bad stomach can't drink it.

It is certainly not something that everyone can drink, because there are some people who have a bad stomach, and if they drink herbal tea, it may make the stomach problem worse.

No, because some physiques are relatively cold, they can't drink herbal tea, but it will aggravate the cold of their body, which is not conducive to the health of the body.

But be careful, you can't leave the tea soup that has been drunk for a long time before drinking, which is very unhygienic. Cold tea beverages produced through strict sterilization measures are drinkable.

In fact, drinking tea can obtain more tea polyphenols and vitamin C from tea, but from the perspective of nutrition and hygiene, after tea brewing, after a long time, the vitamin C and other nutrients in the tea soup will be reduced due to gradual oxidation. In addition, the proteins and sugars in the tea are the medium of bacteria and molds, and the tea soup is not strictly sterilized, which is easy to breed mold and bacteria, resulting in the deterioration of the tea soup*, and the spoiled tea soup is not suitable for drinking. It is recommended that everyone drink more hot tea, because the various active ingredients in tea have high solubility in hot water.

Therefore, drinking hot tea can give full play to the color, aroma, taste of tea and the quality of Tieguanyin tea. In addition, after hot tea enters the stomach, it can soften food, strengthen the contraction of the stomach wall, promote the secretion of gastric juice, and help the digestion of food.
