It is widely believed that breakfast can be limited to a cup of sweet tea. But the fact is that tea infusion inhibits the secretion of gastric juice and bile, suppresses appetite. But there is a feeling of hunger in an unusual time, the daily diet is broken.
You start snacking on the go, more often with sweets, and as a result you risk acquiring a bunch of diseases. The same cautions apply to tea drinkers just before eating. In addition, by reducing gastric secretion, digestion is disturbed, the tannins contained in it block proteins and prevent their absorption. In addition, the aftertaste of tea distorts the taste of many products and does not give the opportunity to enjoy the food. Therefore, it is recommended to use a tea drink no less than 30 minutes before a meal.
By the way, for the same reasons it is not recommended to drink tea in the process of eating and immediately after. Both food and tea lose a significant part of their beneficial properties. It is better to postpone this ceremony for 30 minutes.
Many people like piping hot. Regular consumption of this drink can lead to burns of the mucous membranes of the mouth, esophagus and stomach, and this, in turn, to inflammatory processes and even the formation of scars.
The most serious mistake is made by lovers of too strong tea. This tea contains an excessive concentration of caffeine, theophylline, which in large doses cause our body to work under stress. This can cause rapid breathing and heartbeat, increased blood pressure, overexcitement of the nervous system, insomnia, mood swings, headaches.
The astringent property of tea can lead to constipation. Excess tannin disrupts protein and iron absorption. Therefore, people with anemia need to be very careful about this drink. Fluorine contained in tea in small amounts is necessary and useful, but in excess concentration destroys calcium compounds and, thus, damages the health of teeth and bones.
In addition, it is proved that strong black tea increases intraocular pressure, so it is generally not recommended to use in glaucoma. Excessive diuretic effect of the drink can lead to severe thirst and loss of important trace elements by the body.
Do not insist on tea for a long time, especially for the future. It is recommended to drink tea freshly, insist 1-3 minutes, use a maximum of 20 to 30 minutes. After this time, the drink becomes too strong, the concentration of substances capable of causing harm increases sharply, and the vitamins and organic acids, on the contrary, are destroyed.
The drink, which stayed all night, is completely devoid of useful substances, and if it was also sweetened, then this is a favorable nutrient medium for the reproduction of pathogenic microorganisms.
And, finally, it is completely unacceptable to drink medicine with tea. After all, the infusion of tea is a mass concentrate of biologically active substances, many of which are simply incompatible with medicines. Taking the drug along with tea, you risk getting a weakening or, conversely, an uncontrolled increase in the effect, thereby causing harm to health.
