The tradition of tea drinking has become so firmly established in everyday life that some people can no longer imagine their day without a cup of this tonic drink. There are also opponents of this habit, tirelessly reminding tea lovers of what harmful substances it contains and how it adversely affects the body in general and the nervous system in particular. So who's right? Does tea bring warmth and comfort, or does it pose a serious health problem?
Tea is a strong antioxidant, because it is based on tannins. Interacting with metals, proteins and other elements that enter the bloodstream from the outside, alien to the body, they successfully neutralize potential danger. Unfortunately, this also applies to medicines: the tannins contained in tea will "disarm" them too.
Have you ever noticed that hot tea burns your mouth much less than hot water? This is due to pectins, another type of active substances that make up the tea "bouquet". Pectins instantly envelop the mucous membranes, thus protecting them from possible damage, but nevertheless, you should not drink tea on an empty stomach.
But what about the notorious caffeine, which opponents of the popular drink refer to? Indeed, there is more of it in tea than in coffee. But it is bound by the already mentioned tannins, and therefore does not have a critical effect on the nervous system and is quickly excreted along with toxins.
British scientists have calculated that from 5 kg of custard tea (average annual consumption per person), only 100 grams of caffeine enters the bloodstream, the rest of the volume dissolves in hot water. IT turns out that the daily dose of this substance received by the body along with tea does not exceed a third of a gram, which is completely harmless. But avoid old and overexposed brews, they contain guanine, which is very poisonous indeed. It is not recommended to drink tea after alcohol in order to avoid an increased load on the liver.
Among other treasures that a cup of tea is fraught with, there are key chemical elements for health, such as phosphorus, fluorine, zinc. A few cups of tea a day will replenish the supply of manganese and copper, and a sufficient amount of the latter in the body helps to prevent inflammation.
Speaking of tea, it is impossible not to mention vitamins. Vitamins of groups B and P, which are abundant in tea, will take care of your nerves, liver and blood vessels. When freshly plucked from a tea bush, the leaves are four times richer in vitamin C than lemon. When processing black varieties, it partially disintegrates, but green teas retain almost all of their initial supply.
So, if there are no special medical contraindications, moderate consumption of tea will not harm you, and even be beneficial. To protect yourself from its "overdose" with negative consequences, just make sure that the infusion in your kettle is always fresh and not too strong, and the temperature of the drink in the cup is not too high.
