Side effects or why keep up
Scientists have identified a number of side effects that occur more often with overdose of green tea, which is harmful for both women and men.
Changes the acidity of the stomach
Green tea changes the acidity of gastric juice, increasing it above the norm, which causes irritation of the stomach walls and can cause heartburn. This is the conclusion reached by scientists, studies have shown that tea stimulates the production of gastric acid.
What we can not do immediately after a meal. NO: Walk Many of us believe that eating after meals is good for walking, but it’s not. Walking after eating can cause acid reflux and dyspepsia. Walking is a great way to burn calories. NO: Fruits It is believed that fruits should be used as a dessert after a meal. But actually it is not. Fruits, eaten after the main food comes in contact with it and begins to ferment and soak. This disrupts the normal digestion process.
It is better to eat them an hour before meals or at least 2 hours after that. NO: tea doctors advise not to drink tea after meals, because it contains acids that bind to iron in the body and thus prevent its absorption. When we drink this drink, we do not get the desired amount of iron from food.
To neutralize its effect on the stomach wall, you can add sugar to tea, which again is not welcomed by everyone. It is better to drink the drink after meals or between meals, when the stomach is not yet freed from food.
People with high acidity of the stomach and peptic ulcer need to be more careful in the use of this drink.
That is why the best time for tea is at least one hour after meals. NO: Dream. Most of us like to lie down right after eating, but this habit is bad. In the supine position, a small amount of digestive juices from the stomach merges into the esophagus.
This is why some people have heartburn and go to bed immediately after eating. To avoid this problem, lie down at least two hours after eating. NO: Relaxing bath. Swimming in warm water increases blood flow to the extremities and the entire surface of the body. Accordingly, the blood flow to the stomach decreases. Take a bath or take a bath at least half an hour after eating.
Reduces iron absorption
Since tea is drunk only after a meal, it interacts with substances contained in food. It is established that caffeine, or rather, theine (this is the same caffeine that is contained in tea, differs from caffeine in that it is absorbed only in the intestine), reduces the absorption of iron by 25%. This refers more to the non-haem gland contained in eggs, dairy products and vegetable products.
NO: Smoking Smoking after eating causes irritable bowel syndrome. It also adversely affects the functioning of the large intestine muscles responsible for the final stage of the digestive process. What to do immediately after a meal. YES: Hot water For proper digestion of food in the first hour after eating, the body needs energy and heat. Therefore, it is recommended not to eat cold foods, such as ice cream, immediately after a meal. It is best to drink a few sips of warm water.

Promotes chronic headaches
If a person constantly consumes drinks containing caffeine, the body gradually gets used to it. And with a lack of this "doping" it responds with a long headache. This is a kind of caffeine addiction, causing a kind of breaking with insufficient intake.
§ Chilled tea is also not useful. While warm tea gives vitality, relieves fatigue and brightens the mind, cold tea has unpleasant side effects - it causes an accumulation of mucus and sputum in the body. Avoid too strong teas.

An additional intake of drinks solves this problem in 25-30 minutes, but is it worth it to accustom your body to such an addiction? If there are headaches with a lack of caffeine doping, it is better to completely abandon these drinks. After all, these symptoms will gradually intensify.

Medical experts recognize the fact that caffeine-containing beverages can cause heartburn. This is explained by the fact that during irritation of the mucous membrane by caffeine derivatives, the production of hydrochloric acid increases.
And since the active substances still have vasoconstrictor abilities, this in some measure disrupts the functioning of the sphincter, which does not work in time and passes hydrochloric acid into the esophagus.
Do not drink the drink hot, because it irritates the gastric mucosa more strongly and do not work in the slope after drinking a cup of tea.
Overdose of tea sometimes causes nausea, turning into vomiting, which is rare. This is also associated with a change in the acidity of the stomach and the irritating effect of the active substances on the emetic center of the brain.

Drink tea wisely and be healthy!
It is not a secret for anyone that high-quality leaf tea is a well of useful substances for our body. In fact, the more often we drink tea, the more it is able to strengthen our health.One of the most powerful components of tea are polyphenols, which can slow down the aging process, while strengthening the immune system.
Lipopolysaccharides contained in tea reduce the harm caused by radiation and other toxins. And the caffeine content in this drink can help maintain a clear mind and relieve fatigue.However, the illiterate use of tea can not only level all its benefits, but also harm the body. In today's review, we have collected 9 common misconceptions, having studied which, you will understand how to make friends with the culture to drink tea better.
1. Drink tea on an empty stomach
Drinking tea suppresses the secretion of gastric juice and can reduce the total acid and bile in the stomach. Tea can also affect the body's absorption of proteins and other nutrients. Eating tea on an empty stomach will stimulate the gastric mucosa, resulting in a loss of appetite.
2. Drink too hot tea
A drink with too high a temperature will irritate and burn the throat, esophagus and gastric mucosa. Abuse of too hot tea can lead to scarring. Experts note that the temperature of tea should not exceed 56 degrees.
3. Drink strong tea
Replacing tea can increase its caffeine content, which may further affect our health. Headaches, insomnia, dehydration, problems with digestion - all this can be done by the hands of caffeine. Therefore, try to observe the recommended dosage of tea on the teapot, as well as to monitor its brewing.
4. Make tea too long
If the tea is brewed for too long, then regardless of the water temperature, it will be too strong, sometimes even with bitterness. Experts consider such tea unsuitable for drinking, because vitamins, antioxidants and amino acids are destroyed in it, and the result is not only not very tasty, but not very useful drink.
5. Brew tea too many times.
Most good leafy teas can be brewed only 3 or 4 times, otherwise we risk getting a tasteless and non-flavored drink. Flavored teas should be brewed only 1 or 2 times. The exception is highly fermented Pu-erh and "stable" oolong tea - they can be brewed 5-6 times.
6. Drink plenty of tea before meals.
Excessive consumption of tea before meals can not only affect our ability to distinguish between tastes, making food tasteless, but also hinder the absorption of protein in the body. So try next time to pause for 20-30 minutes before eating, and your digestion will be grateful to you.
7. Drink tea immediately after meals.
All the same tannins of tea are associated with protein and iron contained in food, preventing their absorption by the body. In order to avoid these negative consequences, it is recommended to switch to tea no earlier than half an hour after a meal.
