Can drinking too much green tea cause poisoning? Is drinking too much green tea harmful?

Natural tea drinks, probably not, when it is hot, I often drink three or four bottles a day, but choose well-known brands, such as Uni-President, Master Kong, etc.!

Yes. It's not good to have too much of anything.

Not good for health.

Hehe, in moderation, in moderation.

Probably not, beware of tartar.

Green tea should be drunk sparingly.

Our science teacher said that drinking too much green tea will make you stupid, maybe there is something in it.

As the saying goes, anything extra is bad. The same goes for green tea. Due to its many beneficial properties, it has become very popular among other varieties of tea. The most popular is that it is a very good antioxidant with the ability to increase metabolism and lose weight.

But we should not forget that it is made from tea tree (Camellia sinensis), just like other varieties of regular tea. Green tea differs only in the way the tea leaves are processed. Therefore, the caffeine it contains, like other teas, gives us a refreshing sensation after drinking.

But to reap all the benefits of green tea, we should limit our use to a maximum of five cups of green tea per day to reduce caffeine intake. Otherwise, in the long run, excessive caffeine. Even people with a low tolerance to caffeine may suffer *** even if they increase the amount of tea to five cups.

Excessive amounts of green tea have many *** that can lead to the following health problems

Anxiety, nervous tension and insomnia

No matter how much caffeine green tea contains, it is not a drink to drink before bed. Caffeine itself blocks sleep-inducing chemicals in the brain. Caffeine has a noticeable effect on anxiety and sleep, which varies depending on the person's sensitivity.

Stomach problems -

The tannic acid present in green tea increases stomach acidity, which may cause stomach pain, nausea, or constipation. Therefore, green tea should not be consumed on an empty stomach.

Irregular or accelerated heartbeat

The caffeine in green tea may cause arrhythmias and heart.

High blood pressure-

The caffeine in green tea may raise blood pressure in people with a predisposition to high blood pressure. However, this does not appear to have happened in people who regularly drink green tea or other caffeinated products.

Headaches

Caffeine is a risk factor for chronic daily headache attacks, and although green tea contains much less caffeine than coffee or other kinds of tea, it's best to avoid excessive amounts.

Iron deficiency and anemia-

Green tea reduces the body's absorption of iron. As a result, overdose can lead to iron deficiency and anemia.

Liver disease-

Green tea extract supplements have been linked to several cases of liver damage. Green tea extract may exacerbate liver disease because caffeine in the blood may accumulate and last longer.

Weak bones or osteoporosis -

Too much green tea can lead to frequent urination and can lead to the depletion of calcium in the body. Calcium deficiency can lead to osteoporosis or osteoporosis.

I think drinking too much green tea is harmful to the human body, because the daily intake of water in the human body is limited, if excessive tea consumption will cause too much pressure on our kidneys, which will have some damage to kidney function, so don't drink too much green tea.

It is very harmful, because drinking too much green tea can easily lead to being too energetic, so you can't sleep at night, so it will lead to poor sleep quality.

It is also harmful, for example, it will put you into a state of insomnia, and it will also make your teeth yellow, and even grow some stains.

Personally, I don't think it's true. Tea is the national drink of the Chinese nation, tea has the effect of fitness, thirst quenching, healing diseases, and is full of appreciation and can cultivate sentiment. Most experts say that drinking tea can also prevent cancer, diabetes, and heart disease.

Tea contains a variety of chemical components, and more than 700 known organic and inorganic compounds have been isolated and identified, including primary metabolites proteins, sugars, fats and secondary metabolites polyphenols, pigments, theanine, alkaloids, aromatic substances, saponins, etc. Studies have shown that tea has a preventive effect on cancer.

Tea drinking can inhibit the occurrence of oral tumors in golden gosters induced by carcinogen dimethylbenzanthracene; Green tea, black tea, Tieguanyin, flower tea and large-leaf green tea can all inhibit the occurrence of esophageal tumors by blocking the synthesis of carcinogen methylbenzylnitrosamine precursors in rats. No matter what kind of tea, it has different degrees of preventive effect on chemical carcinogenic or transplanted tumors in animals.

Experts also screened the 18 main components of tea, and found that tea polyphenols and catechin monomers have a preventive effect on the occurrence and development of cancer, tea polysaccharides and caffeine also have a certain effect, and the oxidation products of tea polyphenols, tea pigments and tea polyphenols are also effective. Tea pigment is the main ingredient in black tea and oolong tea.

Epidemiological studies have shown that smoking is associated with human tumors and lung cancer in particular. The results showed that tea drinking had a significant protective effect on oxidative damage and DNA damage caused by smoking.

This news is fake, but drinking green tea is still good for your health.

This news is certainly not true, because drinking too much green tea is good for the human body.

Green tea invigorates people's spirits and enhances their thinking and memory skills.

Green tea has some anti-cancer effects because it is rich in a polyphenol called catechin.

False, this news is deceitful and cannot be believed, drinking properly is good for the body.

This one is fake, there is no scientific basis, and it is still okay to drink some tea once in a while.

This should also be possible, and you can't eat or drink anything in excess.

If you drink green tea, it will have some anti-cancer effects and will not cause cancer.

This claim is false because there is no scientific basis for it.

As a matter of common sense! No! If you're allergic to green tea, you'll spit out...

Whether you vomit or not, it depends on your physical condition, whether you are allergic to green tea, etc., to understand what kind of physique you have, whether it is cold or hot.

It is not poisonous, and there is science that shows that long-term chewing of tea leaves can help freshen breath.

Chewing tea residues after drinking tea can protect your teeth. However, it should be noted that the time for chewing tea leaves is 1 2 minutes. Because tea pomace is also rich in tannic acid, it is easy to combine with food to form tannin protein, forming a precipitate, which affects the absorption of nutrients such as protein, iron and vitamins in the mucosa of the digestive tract.

In addition, too much tannin can also cause constipation, so "just chew but not swallow" is the best way.

Drinking tea depends on the physique, chewing tea residues is the same, green tea tea residues have a good heat-clearing and detoxification effect, suitable for people with hot constitution. Such people are often accompanied by constipation, bad breath, red tongue, yellow tongue and other manifestations of stomach heat. The medicinal properties of black tea are relatively warm, which is suitable for people with cold constitution who are afraid of cold, cold hands, cold hands and feet, and white tongue.

There is absolutely no poison. But why eat the tea leaves? It doesn't taste good.

It's not just green tea. Whatever is in moderation.

When the tea is strong, the phenomenon of tea drunkenness will occur. Drinking strong tea before and after meals for a long time can cause adverse consequences such as indigestion, constipation, nutritional disorders and anemia, so it is not advisable to drink tea within half an hour before and within an hour after meals.

The so-called strong tea refers to the tea soup in which the amount of tea used exceeds the constant amount (3-4 grams of tea per cup). Strong tea is not suitable for many people, such as drinking strong tea at night, which is easy to cause insomnia. People with tachycardia, heart disease, gastric ulcer, neurasthenia, weak body and cold stomach should not drink strong tea, otherwise the disease will be aggravated.

It is also not advisable to drink strong tea on an empty stomach, otherwise it will often cause stomach discomfort, and sometimes even heart palpitations, nausea and other uncomfortable symptoms, and "tea drunkenness" will occur. After the appearance of "tea drunkenness", you can eat it.

One or two candies, drink some boiling water to relieve it.

Moderate tea consumption has a certain health care effect on the human body. It can improve the spirit, remove fatigue, help digestion, reduce inflammation and sterilization, prevent and treat intestinal infectious diseases, prevent heatstroke and cool down, and quench thirst.
