What is the harm of drinking tea to the body!

Whatever coffee is good for the body, tea is good for the body.

Traditional Chinese medicine has said that if anything is excessive, it is not good, and drinking tea in moderation is good for the body, because tea contains tea polyphenols and other beneficial ingredients, and water is also necessary for the human body, and the effect is also very large, so you can drink tea and water in moderation every day, and you can't drink too much.

Benefits of drinking tea.

1. Tea can be drunk**.

Tea contains catechins, cholesteenone, caffeine, inositol, folic acid, pantothenic acid and other components, under the comprehensive action, has the effect of preventing and inhibiting obesity.

2. Drinking tea can prevent tooth decay.

Drinking tea or rinsing your mouth and brushing your teeth with tea can not only remove bad breath, but also prevent tooth decay. Since the 70s, he has been studying the efficacy of tea in preventing tooth decay, drinking tea, rinsing his mouth with tea soup, brushing his teeth, or using toothpaste containing tea, but brushing his teeth with tea soup is the best.

This is because tea contains fluorine, which has a great affinity for calcium in the teeth and can become a kind of "neon apatite" that is difficult to dissolve in acid.

3. Tea can prevent cardiovascular diseases.

Drinking tea also reduces cardiovascular diseases such as high blood pressure and cholesterol.

4. Tea is a good medicine for intestinal diseases.

The polyphenols in tea can make proteins coagulate and precipitate. Tea polyphenols bind to single-celled bacteria, which can coagulate the egg and kill the bacteria together with the therapeutic net.

For example, if the serious cholera bacteria, typhoid bacillus, and E. coli are soaked in strong tea soup for a few minutes, most of them will lose their mobility, which is good for preventing intestinal infectious diseases.

Disadvantages of drinking tea.

1. Affect normal digestion.

A person's normal daily secretion of gastric juice is liters, and these gastric juices are able to properly digest the food that a person consumes every day. When a large amount of strong tea is drunk, it will dilute the gastric juice and reduce the concentration of gastric juice, so that the gastric juice cannot digest food normally, resulting in indigestion, bloating, abdominal pain and other symptoms, and some even cause duodenal ulcers.

2. Tea hinders the body's absorption of iron.

Tea contains tannic acid, black tea contains about 5%, and green tea contains about 10%. When the human body drinks a large amount of strong tea, the combination of tannic acid and iron will be more active, which will bring obstacles and affect the absorption of iron by the human body, making the human body manifest as iron deficiency anemia.

3. Drinking strong tea is easy to produce constipation.

The tannic acid in tea can not only combine with iron, but also combine with the protein in food to form a lumpy, indigestible and indigestible tannin protein, which leads to constipation. Constipation can be exacerbated by older people who suffer from constipation.

4. Strong tea causes increased blood pressure and heart failure.

The caffeine in strong tea can cause the human heart to beat faster, which can increase blood pressure; At the same time, a large amount of strong tea liquid enters the blood vessels, which can increase the burden on the heart, produce uncomfortable symptoms such as chest tightness and palpitations, and aggravate the degree of heart failure. There is a limit to everything. Drinking weak tea can be healthy, while drinking strong tea is harmful to health.

You can drink it for a long time, but I don't recommend that you drink green tea for a long time, usually drink black tea, black tea, and remember not to drink green tea for a long time.

Not good. Pure water is the easiest to be absorbed by the human body, and people need a lot of water a day, and if you completely replace it with tea, you will drink too much tea.

Drinking tea for a long time is good for the body. Tea contains tea polyphenols and many trace elements that the human body needs. But instead of the water you usually drink, it's not good.

Excessive tea consumption not only increases the occurrence of diseases such as plaque and bone spurs, but also makes the color of the teeth too yellow, affecting personal image. Therefore, it is not advisable to replace daily drinking water with tea.

It's not good, anything in this world will be bad for the body in the long run!

"Tea culture" has a history of thousands of years in China, and from ancient times to the present, people have always had a preference for tea. In the process of tasting tea, you can cultivate your self-cultivation and gradually calm down your impetuous mood. On top of that, tea is rich in nutrients and is very beneficial to the body.

It is not denied that tea polyphenols, amino acids and other substances in tea can indeed supplement nutrients for the body. At the same time, it can also play a role in health preservation, remove free radicals in the body, and lower blood lipids and blood pressure. Even, different teas have different effects.

It is precisely in this way that tea is endowed with a veil of mystery. Many people think that if they want to live a long life and be healthy, they must develop the habit of drinking tea. In fact, this kind of thinking is wrong, because everything is too much, and once it is excessive, it will have a bad effect.

In a nutshell:Although tea is good, it cannot replace plain water.

Although tea is rich in nutrients, it is not boiled water after all, and it still cannot meet the body's need for water.

There is one thing to keep in mind about drinking tea:Do not drink in large quantities so as not to harm your health .

Drinking tea scientifically can achieve the expected health effect

1. Don't drink strong tea

At any time, do not drink strong tea to avoid the consequences of increased "excitement" and affect the nervous system. Tea is known to contain a banned ingredient, and the higher the concentration, the higher its content. Therefore, after drinking high-strength tea, the body will be particularly excited, seriously disrupting the biological clock.

2. Tea time

Between three and five p.m., it's the best time to drink tea.

3. Don't drink tea after drinking

After drinking, remember not to drink tea again, otherwise you will suffer from endless problems. Many people have the impression that drinking tea after drinking alcohol can relieve hangover and drive away the discomfort of drunkenness, but in fact, there is no scientific basis for this idea. The study found that:

Drinking tea after drinking alcohol is not conducive to the metabolism of alcohol, and even increases the burden on the kidneys.

4. Control the amount of drinking

Dizziness, gastrointestinal upset. So, just drink 5g of tea every day.

If you want to achieve the purpose of health preservation through tea, there is another important point:That is to choose the right tea for yourself. You must know that there are many varieties of tea on the market, and each tea has different effects, so you should pay special attention when choosing.

If you are worried that you will not be able to choose, you can ask a friend who understands tea or the owner of a tea shop to help you when buying tea. Because I know enough about the characteristics of tea, I can recommend tea that is more suitable for me. Of course, you need to be honest with them about your needs and situation.
