What teas should not be drunk in daily life?

First course tea. Because in ancient times, tea was inevitably purified by pesticides, fertilizers, dust and other materials in the process of planting, processing and packaging. The first tea is actually the water for washing the tea, and it should be rushed into the boiling water as soon as possible, so that the tea brewed is the most hygienic tea.

Burnt tea, this kind of tea is in the process of frying, the stir-fry time is too long, resulting in the loss of all its nutrients, and the taste becomes poor.

In daily life, we must pay attention to selectivity when drinking tea, moldy tea leaves, overnight tea, and tea that has been brewed more than 4 times can not be drunk.

I feel that there is a lot of tea that can be drunk in life, and there is nothing that cannot be drunk.

Don't drink overnight tea, because the tea that has been left overnight no longer has the taste it had at that time, and it will produce many other substances.

Tea made overnight, tea brewed in water that has been boiled repeatedly, and tea made from moldy tea leaves cannot be drunk.

Overnight tea can not be drunk, the tiny particles in the tea will condense and precipitate some changes, if you drink strong overnight tea for a long time, it will increase the chance of stones in the body.

In daily life, the last tea that can be drunk is overnight tea. There will be a lot of nitrites, which are harmful to the body.

Raw water has a wide variety of bacteria, viruses, and zoonotic parasites that are harmful to humans. Aging water: commonly known as "stagnant water", that is, water that has been stored for a long time, thousands of boiling water:

A thousand boiling water is water that has been boiled on a stove overnight or for a long time, and water that has been boiled repeatedly in an electric water heater. Steamer water: Steamer water is leftover pot water such as steamed steamed buns, especially steamer water that has been used repeatedly and repeatedly, and the nitrite concentration is very watery.

Unboiled water: The tap water that people drink is treated by chlorination and sterilization. 13 kinds of harmful substances can be separated from chlorine-treated water, among which halogenated hydrocarbons and chloroform are also carcinogenic and teratogenic.

Moldy tea, tea with peculiar smell, overnight tea, these teas are harmful to health, never drink these teas.

If the brewing time is too long, the tea polyphenols, lipids, aromatic substances, etc. in the tea can be automatically oxidized, not only the tea soup is dark in color, poor in taste, low in aroma, and loses its taste value; Because the vitamin C, vitamin P, amino acids and other nutrients in tea are reduced due to oxidation, the nutritional value of tea soup is greatly reduced; At the same time, because the tea soup has been left for too long and polluted by the surrounding environment, the number of microorganisms (bacteria and straight bacteria) in the tea soup is large, which is very unhygienic.

Overnight tea is not drinkable, and it is very bad for the body to have carcinogens in overnight tea.

Although the mother-in-law Ding tea is very good, it is said that if the spleen and stomach are naturally cold, people are not a box of this tea.

The first tea is the first brew of tea, this tea is to wake up the tea, so that the tea leaves can play the best taste in the next few bubbles, so it is recommended not to drink the first tea.

Because the tea is not properly kept, it is easy to absorb moisture and mildew, and some tea lovers are reluctant to discard the mildewed tea out of tea conservation. Spoiled tea contains a large number of substances and germs that are harmful to the human body, and it should never be drunk. If high-quality tea is left for too long after brewing, the tea soup will also deteriorate due to oxidation and microbial multiplication, so you should not drink such tea again.

Cold tea, tea is suitable for warm drinking, cold tea has the disadvantages of stagnation and phlegm. Warm tea makes people feel refreshed, deaf and clear; Cold tea has a stagnation of cold and phlegm accumulation on the body.

When drinking tea daily, you must not drink strong tea for a long time, because strong tea can increase blood pressure, cause palpitations, shortness of breath, and you can not drink overnight tea, or because there are harmful substances in the overnight tea, it will damage the internal organs of the human body, and you can't drink tea made in cold water, and it is very easy to have diarrhea when you drink such tea.

Don't drink Zheng Jing tea before going to bed at night, and also pay attention to the appropriate amount, and don't drink tea on an empty stomach, and don't drink tea immediately after meals, which will cause the slow nutrients in the food to not be fully absorbed, and it will also affect the absorption of nutrients. And don't drink the tea after it's cooled, and people with stomach problems shouldn't drink tea to disturb Cong Finger.

Don't drink strong tea after getting drunk, generally you can't drink strong tea when taking medicine, don't drink tea with you on an empty stomach, it's best not to drink tea before going to bed, don't drink overnight tea, don't drink the first tea, it's best not to drink some inferior reed or quality tea or bent tea, and generally don't drink a lot of tea before meals.

Do not drink tea on an empty stomach, do not drink tea before going to bed, etc. Do not drink tea on an empty stomach, it will cause stomach discomfort; Do not drink tea before going to bed, it will excite the nerves and make it impossible to sleep.

Don't drink tea before going to bed, there will be some problems on the body, and insomnia is likely to occur, and in general, you should drink tea at dinner, which can also have a good fat scraping effect.

Tea contains nearly 400 chemical components. Drinking tea has the functions of refreshing the mind, preventing and treating diseases, relieving hangover, and removing tobacco poisons. However, some of the following people should not drink tea.

1.Children's tea contains tannic acid, which can precipitate iron in food, and can oxidize ferric iron to ferric, so that iron cannot be utilized, resulting in iron deficiency in the body. If you develop the habit of drinking tea for a long time in childhood, it is easy to cause iron deficiency and lead to anemia, which will affect children's intellectual development and reduce their intelligence (including comprehension, memory, and reaction ability).

Therefore, children should not drink tea, let alone drink tea for a long time.

2.Drinking tea in malnourished people can affect the body's absorption of protein. After the tannic acid in tea is combined with protein to form tannic acid protein, the gastrointestinal tract cannot digest and absorb it. Malnourished people who drink tea will have worse nutrition.

3.The tannic acid in tea in patients with anemia and pregnant and lactating women will affect the absorption and utilization of iron, aggravating the degree of anemia. Pregnant and lactating women should not drink tea, otherwise, it is easy to cause anemia and other diseases in adults or fetuses and infants.

4.Tea for cerebral arteriosclerosis patients contains caffeine, theobromine and other substances, which have obvious excitatory effects on the central nervous system. Therefore, such patients should not drink tea.

5.The caffeine in tea for patients with high blood pressure and heart disease has a stimulant effect, which will increase blood pressure and increase heartbeat, so patients with high blood pressure and heart disease should not drink strong tea.

6.The caffeine in tea for patients with chronic diseases such as neurasthenia, insomnia, hyperthyroidism, tuberculosis and so on is exciting, which can cause an increase in basal metabolic rate, thus preventing these patients who need to be quiet from getting good rest and sleep.

7.The tannic acid in the tea for constipation has an astringent effect and can lead to aggravation of constipation.

Although it is good to drink tea, these 3 types of people are not suitable for drinking, so be careful that the more you drink, the more you will get on your body.

Do you still remember an ancient text "Bian Que Meets Cai Huangong" that I studied in a Chinese textbook? In the end, Bian Que shook his head and said: "The disease is in **, and it can be cured with a hot compress; The disease is in the muscles, and acupuncture can go to the disease; If the disease is in the stomach and intestines, it can also be rescued with a fire-clearing agent; Sick to the bone marrow, that is doomed to death, irretrievable.

Now that Huan Gong has repeatedly refused to be treated, he has become ill to the bone marrow, and there is nothing I can do! ”

This story confirms the "Yellow Emperor's Neijing" in the "Yellow Emperor's Inner Canon" that "the upper treatment cures the disease, the Chinese medicine cures the desire to disease, and the lower medicine treats the disease". And this practitioner is precisely the one who always pays attention to himself - only himself. Why do you want to bring up this topic with you today?

Because only when you have the correct thinking and cognition, can you avoid detours in action. Today, I will talk to you about the following three types of people's ideological awareness that need to be cautious when drinking tea.

1. People with iron deficiency anemia need to be cautious when drinking tea.

The tannic acid in tea will undergo a complexation reaction with iron, forming insoluble iron tannin in the digestive tract, which will inhibit the absorption of our non-heme iron. If iron is not absorbed well, it will lead to anemia, so patients with anemia need to be careful when drinking tea;

This is also one of the main reasons why female tea lovers should pay attention to drinking tea cautiously before and after menstruation and during menstruation. Because during women's menstruation, if they are anemic, then the abdomen will be painful and unbearable, which is definitely not something that a bowl of brown sugar ginger water can do. Sometimes it hurts to the point of breaking out in a cold sweat.

2. People with neurasthenia and heart disease should be cautious when drinking tea.

The caffeine in tea can make people excited, make the heart beat faster, cause the basal metabolism to increase, and increase the burden on insomnia and the heart.

3. People with gastric ulcers and duodenal ulcers need to be cautious when drinking tea.

Let's listen to Professor Dai Guangqiang's opinion, gastric ulcers, including duodenal ulcers, are due to excessive gastric acid, which may cause gastric mucosa ulcers, and drinking strong tea is one of the causes of gastric ulcers. After drinking strong tea, the central nervous system is excited, and the central nervous system stimulation will strengthen the activity of the stomach, and at the same time, the peristalsis of gastric acid will also increase. Especially in the case of an acute attack, you should pay more attention to drinking tea, do not drink strong tea, you can drink a little weak tea.

We know that among the causes of gastric ulcers and duodenum, there is also a factor that is Helicobacter pylori, Helicobacter pylori is sensitive to tea, if we drink some weak tea (does not affect the secretion of gastric acid, or has little effect) The relevant components in the tea can inhibit or even kill Helicobacter pylori. If it is not an acute attack, it is still beneficial to duodenal ulcer and gastric ulcer.

Do you remember these three types of people? Next, look at yourself from the perspective of being a doctor, whether you belong to the type of tea that needs to be cautious, if not, then congratulations, you can drink tea with confidence. If yes, then congratulations, you have learned the relevant knowledge and successfully avoided becoming the next Cai Henggong.

Learn to drink tea. The days can continue to be busy and ordinary.

But the heart will be slowly refined.

Make drinking tea a habit.

Delicacy will also become the norm of the day.
