Chinese scientists say that 15 minutes after brewing, harmful substances begin to appear in black tea.
Scientists say that the more toxic the tea, the more it contains. Well-known nutritionist Yelena Solomatina explained the disadvantages of the old tea.
"Tea contains various essential oils, and when hot water is poured on them, some of these oils come out of the tea leaves and spread on the surface of the water in the form of a thin layer. We can't see it immediately while drinking tea, as the glass is emptied, a black stain appears on the walls of the cup. Organic compounds, tannins, etc. are added to this layer. includes. Upon contact with air, these substances oxidize, and pathogenic microflora begins to form in the glass. "Especially if you drink tea with sugar, you create a warm, moist and sweet food environment that is necessary for the formation of germs," the expert said.
According to Yelena Solomatina, this is when the fungus begins to grow there, entering the body and poisoning it with mycotoxins. In addition, even if fresh hot water is poured on yesterday's tea leaves, the toxic effects do not disappear. Mycotoxins re-enter our body.
"Of course, you will not be poisoned by tea leaves. However, our body will begin to fight against this pathogenic microflora, spending its energy and resources on it. As a result, the resistance system weakens. As a result of interaction with oxidation products, allergies and intestinal disorders can occur. As the bloodstream carries toxins secreted by microorganisms throughout the body, a significant blow is dealt to the liver. The heart can also be affected. However, this does not happen immediately, but after a while it affects.
The nutritionist added that the situation with tea bags is also ambiguous. Colors and additives are added to them.
