This drink is not so harmful to give it up completely, but in such cases it is recommended to drink it only in the first half of the day. But drinking tea with milk at night with such diseases would be very helpful.
Hypertension, diabetes. If there are problems with the heart and blood vessels, as well as frequent pressure surges, drinks such as tea should be used with caution, as they are caffeine-containing.

If you, after drinking a couple of cups of green tea, notice increased irritability, sleep problems, trembling hands, increased heartbeat, upset stomach, become irritable, notice loss of appetite, rash or "goose bumps", frequent urination, nausea - then you are one of those people who have caffeine sensitivity.

For the normal operation of the human body, such minerals are necessary in small doses, with increasing doses and when they are received in large quantities, they can cause intoxication.
Michael white — Dr. Washington University, in 2005 raised the question about the dangerous content of an element such as fluoride in tea. He was able to diagnose such a rare disease in a middle-aged patient as fluorosis, which is characterized by the presence of elevated fluoride levels in the bone. It turned out that this woman had a habit of drinking about seventeen cups of tea a day!

Green tea has a high concentration of polyphenols, in other words, tannins. In essence, they are antioxidants, and in small quantities are useful, but if you allow an overdose, you can cause a severe blow to the liver.

3. Harm of green tea - its side effects
The Chinese use green tea for more than two thousand years. But somewhere in the six hundredth year of our era in China, green tea was not used as a drink, but only as a remedy.

If you were looking for manufacturing

Such a drink in some cases is even considered an excellent medicinal and prophylactic agent, but this does not mean that it can be consumed in any quantities. If you drink too much green tea, it can lead to unpleasant consequences. As a rule, the nervous system suffers first. The person feels over-excited or even irritable.

An adult is recommended to drink no more than 6 cups of not too strong green tea per day. If you have already neglected this advice, drink sweetened water and eat sweet fruits. This will help to deal with the symptoms.

The negative impact of green tea on the body

It is important to remember that drinking green tea leads to a decrease in pressure. If it is too high, this drink will help to gently correct the situation.

In particular, there is a risk that symptoms such as nausea, cold sweat, dizziness, blackening of the eyes, weakness will appear.

The effects of green tea on the body may vary. This is especially the case when it comes to tea with special additives that can not be transferred by any person.

There are even representatives of special "risk groups" who should not consume green tea in large quantities.

Pay attention: representatives of risk groups should consult with your doctor about the amount of tea you can drink during the day. The fact is that the optimal dose for them may not be 5-6, but, for example, 3-4 cups.

According to research results, green tea drunk on an empty stomach strongly irritates the mucous membrane. If you drink it on an empty stomach too often, you can get gastritis or an ulcer. That is why it is strongly recommended not to use green tea in the morning half an hour before breakfast, as described in some diets. Drinking it just before a meal is also not worth it, because it will worsen the absorption of protein by the body.

Green tea combined with alcohol

By itself, green tea in small quantities has a beneficial effect on the kidneys and liver, and can even improve their performance. This, however, does not apply to cases where such a drink is used together with alcohol, as well as shortly before or after it. The fact is that green tea, combining with wine, vodka, champagne and any other alcoholic beverages, releases toxic substances that can cause very serious damage to the liver and kidneys.

Even in ancient China, people noticed that drinking green tea soon after wine caused puffiness, back pain, deterioration of the kidneys, discomfort in the bladder, and the appearance of heaviness in the body and sputum. Moreover, according to doctors and scientists, such a drink can cause very serious harm to the body, even if it is consumed several hours after drinking alcohol. In a word, even in the morning after a stormy night, it is better to give preference to other drinks.

Poor green tea

Low quality green tea is one of the most harmful drinks. The use of poor-quality raw materials or non-compliance with the terms and conditions of storage can lead to the deterioration of the drink. Of course, you can’t drink it after that.

Green tea of dubious quality can contain a lot of toxins that poison the human body. Regularly consuming such a drink, you may even notice significant deterioration in well-being.

In order not to purchase low-quality goods, give preference to tea from well-known companies, check the expiration date and use the services of well-known stores with a good reputation. Also note that it is not recommended to choose a drink with flavors or big amount additional ingredients, especially if you are prone to allergies.
