Tea is a delicious drink with a huge number of useful qualities. However, do not forget that excessive consumption of tea can lead to undesirable effects. Much also depends on what kind of tea a person prefers to drink.
Contraindications to drinking tea
Even high-quality tea of elite varieties can cause deterioration in health, since it contains caffeine, a substance that has a stimulating and aphrodisiac effect. In small quantities, it is good for the body.
However, in Russia it is not customary to limit tea drinking to one cup, so tea drinkers have a high risk of developing cardiovascular diseases and disorders in the functioning of the nervous system. Green tea is believed to be more beneficial. On the contrary, it is in it that the most caffeine is contained.
Theophylline, a substance essential for the good functioning of the blood vessels, kidneys and respiratory organs, is also present in tea. With its overdose, increased production of stomach acid begins. Therefore, tea is not recommended to be consumed on an empty stomach. Contraindications to strong tea are diseases of the digestive tract and the presence of increased acidity of gastric juice.
There is an assumption that an excessive love of tea leads to the destruction of calcium, as a result of which bone tissue becomes thinner. This circumstance can provoke osteochondrosis and osteoporosis. Green tea has a negative effect on tooth enamel, causing the progression of tooth decay.
The harm of tea for pregnant women has been practically proven, since the presence of caffeine negatively affects the development of the fetus. In addition, green tea interferes with the full absorption of folic acid, which plays an important role in the early months of pregnancy, providing immune protection for the mother and baby.
Difference between cheap and elite teas
If moderate consumption of properly brewed elite tea does not lead to pronounced negative effects, cheap tea varieties cause great harm to health. The use of common sachets is especially dangerous.
Most often, these types of tea are generously flavored with dyes and flavors. An honest manufacturer warns the buyer about the presence of these ingredients. However, the addition of flavors to 100% natural teas is not excluded, to ensure the imaginary freshness of an expired product. Usually, such a surprise can be expected when buying tea bags, which consists of finely chopped leaves of not the highest quality.
Is tea harmful and how much is an endless dispute between adherents of the tea tradition and its opponents. Meanwhile, connoisseurs of the delicate tart taste of freshly brewed tea continue to drink this pleasant drink. However, you should be more careful about your health and use only high-quality varieties in a moderate amount.
