Harm green tea

Another legitimate question. And what are the harmful properties of green tea? In fact - in addition to a huge plus green tea has a number of drawbacks. While it would be correct to say - a number of contraindications. In that case, if you have the following diseases, from your green tea is better to refuse. Or, at least, to reduce its consumption to the minimum possible. So:

  • Hypertension

Some people believe that green tea increases the pressure is absolutely not. However, this is not so - because it contains considerable amounts of caffeine. And so people who are prone to high blood pressure, you can not get involved in green tea. Especially if hypertension occurs in an acute form. The most that can afford such people - it is one - two cups of weak tea. In this case, damage to the green tea will be minimal.

  • Hyperthermia

As mentioned above, in no case should not drink green tea at high temperature of the body. Otherwise there is a risk disruption of the urinary system.

  • Gastrointestinal disease

Green tea stimulates increase in gastric acidity. Therefore, it is not recommended to drink for people suffering from gastritis with high acidity, gastric ulcer and duodenal ulcer.

Try to completely eliminate the green tea. But in the case of the low acidity of the stomach green tea can be very useful. But do not forget that pre-need to consult with your doctor. In the end, only after some research you can find out the level of acidity of gastric juice. And they can spend only a doctor.

  • Problems with the central nervous system

Since the composition of green tea contains a large quantity of such irritants as theophylline, theobromine, and caffeine, which act on the central nervous system stimulant, it is not recommended to use for people who suffer from insomnia and hyperexcitability. Otherwise, the situation will only grow worse - damage of green tea in this case, there is no doubt.

Also, remember that green tea in any case you can not drink in the day, when you drink alcohol - even if it is very low-alcohol drinks. But very often people try to get rid of the feeling of intoxication in this way, knowing nothing about the harm of green tea in a given situation.

Certain substances contained in green tea, are reacted with molecules of ethyl alcohol, resulting in a large number of aldehydes. And these aldehydes have the most negative impact on the work of the urinary system. As a result, the most harmless, what can turn such an attempt to improve the state of health - is the development of a strong swelling. In the worst case - and at renal failure.

And finally I would like to draw attention to the tea itself - the use of green tea in tea bags is highly questionable. Try to choose and acquire elite varieties of green tea. It costs not too expensive, and the benefits - are far higher. Drink green tea with pleasure and be always healthy!
