Бактерии и плесень: чем опасен неправильный чай

Brewed with enough hot water, the tea can be hazardous to health, warn German experts. All because of bacteria, mold and other pathogens that may be contained. Boiling water can kill most of them.

Tea can be dangerous for health, if it is to brew with boiling water. About it reports the edition Focus Online, citing data from the German Federal Institute for risk assessment.

Tea is a natural product and may contain bacteria (e.g., Salmonella), yeast and mold. Therefore, in the preparation of the drink should strictly follow the instructions from the manufacturer: pour the tea leaves with boiling water and leave to brew for five minutes.

“Only if you brew tea with boiling water and infuse it enough time, you can ensure that the selected pathogens will die”, — the experts of the Institute.

They add that drinking tea, which has stood for more than a few hours is not worth it — if some pathogens were able to survive during this time they will multiply and can harm your health.

However, drinking too hot tea should not be: it may increase the risk of developing cancer of the esophagus.

This is because too hot tea damages the esophageal mucosa, leading to its inflammation. Also possibly impaired barrier function of the esophagus leads to a more pronounced exposure to carcinogens.

“Many people like to drink tea, coffee and other hot drinks — said the oncologist Farhad Islami. — However, to our knowledge, the use of too hot tea can increase the risk of developing esophageal cancer, so it is advisable to wait for hot drinks to cool before drinking”.

The optimum temperature of tea — not more than 60°C. This does not mean that every time before a Cup of tea you put in a Cup thermometer — most people drink tea temperature to 50°C. But piping hot drinks should abandon the habit to pour a boiling water.

Also it is necessary to abandon tea bags — he generously “enriched” body microplastics. Earlier tea bags were made mainly from paper, but now many manufacturers began to switch to plastic mesh. Data about how the microplastics affect human health, yet not very much. The who notes that the unambiguous harm to the.

However, animal studies show that microplastics may cause damage to the intestines and liver.

As found by canadian researchers, immersed in water with a temperature of 95°C plastic tea bag almost instantly allocates about 11.6 billion particles of micro-plastic and 3.1 billion particles neoplastika. In this case the earlier calculations showed that during the year a person consumes only about 74 thousand particles of micro-plastic.

Particles less than 150 microns can pass through the intestinal wall and penetrate into the blood cells and organs. In addition, many plastic components have a negative impact on the endocrine system, and their permanent presence in the body is fraught with serious consequences.

Scientists immersed in the water, visited the tea bags, Daphnia. The results were disappointing — the higher was the concentration of plastic, the more violations in the development and behavior of the crustaceans, the body of which he fell, was observed by the researchers.

Experts noted that it is first necessary to carefully examine the packaging. It should be on the product name, composition, address of manufacturer, shelf life, storage conditions and method of preparation.

It is also important to dry the tea leaves were of equal size, density and twist. You need to pay attention so that the content was not present stems, tea-crumbs and broken leaves.

In addition, according to experts, after brewing a quality tea should have high transparency, rich dark color and tart flavor. If this burning smell, mould and damp can talk about the danger of the product for health.
