"Thermos cup tea into poisonous tea, toxic and carcinogenic?"
35-year-old Chu Sheng (not his real name) likes to use his work breaks to make a cup of tea to soothe his tired body and mind. He uses a beautiful-looking stainless steel thermos cup, and habitually pours a spoonful of high-quality green tea into it every day.
Chu Sheng, who had been busy all morning, urgently needed a cup of tea to refresh himself. He couldn't hold back his inner craving, hurriedly brewed a cup of green tea, and took a sip, only to find that the taste was unusually bitter, accompanied by a pungent smell.
Chu Sheng felt that something was wrong, but he thought that it might be a problem with the quality of the tea, so he took out the tea leaves and prepared to pour them out.
However, he suddenly felt a sharp pain in his stomach, and a feeling of dizziness followed. He struggled to call the emergency services.
01Why did you drink tea to yourself and go to the hospital?
That's because we overlooked the most important point: the material of the inner tank of the thermos cup.
Some thermos cup liner materials may contain harmful substances, such as chromium and manganese in stainless steel, which may be released at high temperatures for a long time.
When the nutrients in tea react chemically with these harmful substances, some compounds that are harmful to the human body will be produced, resulting in discomfort and even poisoning symptoms for drinkers.
The choice of tea and the method of brewing also affect the safety of tea.
If you choose unqualified tea, or use improper tea brewing methods, pesticide residues, heavy metals and other harmful substances in the tea may dissolve into the tea, causing harm to human health.
The long-term sealing and insulation of the thermos cup is also easy to cause tea fermentation, especially some easy-to-ferment ingredients such as red dates, wolfberries, etc., which are easy to produce gas at high temperatures, resulting in an increase in pressure in the thermos cup and even an explosion.
The paramedics quickly arrived and found that Chu Sheng had fallen into a coma. The doctors immediately conducted a comprehensive examination of him and found out the source of the problem - the inner liner of the thermos cup he used was not made of standard material and contained harmful substances.
Under the high temperature for a long time, the harmful substances in the thermos cup react with the nutrients in the tea leaves, forming a toxic substance, which poses a serious threat to human health.
Chu Sheng was rushed to the hospital for treatment, but his condition deteriorated day by day. After further examination, the doctors were shocked to announce the astonishing result - Chu Sheng was suffering from a serious cancer, which was caused by drinking contaminated tea for a long time.
02Choose the right material to be healthy
The material of the inner liner of the thermos cup is very important for our health. At present, the main materials of the thermos cup liner on the market are stainless steel, glass and plastic. Among them, stainless steel vacuum cups are usually divided into three codes: 201, 304 and 316.
201 stainless steel: It is a non-food grade material, which is easy to release harmful substances, and long-term use may affect physical health, so it is not recommended to choose.
304 stainless steel: It is a food-grade stainless steel, which is acid-resistant, corrosion-resistant, relatively safe and reliable. However, pitting corrosion can occur when encountering chloride-containing substances such as salt solutions, so care should be taken to avoid them.
316 stainless steel: Molybdenum metal is added on the basis of 304 stainless steel, which is more corrosion resistant, but the price is relatively high.
Chu Sheng's relatives and friends were devastated when they heard the news. They were all saddened by Chu Sheng's dismal death. This once sunny and lively 35-year-old man left in a hurry because of a cup of bitter tea, leaving endless sadness and regret.
03 Do you know these common senses?
Beverages suitable for thermos include tea, coffee, milk, juice, etc.
Some drinks can effectively maintain the temperature in the thermos cup, which can not only keep warm, but also maintain the taste and nutrition of the drink, bringing us a comfortable drinking experience.
Some light and easy-to-digest drinks are also suitable for thermos cups, such as clear soup, porridge, soy milk, etc. These drinks are nutritious, easy to digest and absorb, and a convenient and nutritious choice.
Not all drinks fit into a thermos!
Some carbonated drinks, fruit vinegar drinks and other drinks containing a large amount of gas are not suitable for loading into the thermos cup, because the high temperature environment will increase the pressure inside the drink, resulting in the danger of explosion of the thermos cup.
Similarly, some perishable beverages, such as drinks containing dairy products and fresh fruit juices, are not suitable for insulated cups, because the high temperature environment is easy to breed bacteria, resulting in spoilage of the drink and causing harm to health.
The doctor reminds that. However, tea leaves tend to lose their original aroma when exposed to high temperatures for a long time, the taste becomes more bitter, and the nutritional value is also impaired.
[Important Notice]: The above article focuses on the safety issues of thermos cup tea, including choosing the right thermos cup material, avoiding the loading of easy-to-ferment ingredients, and the impact of long-term high-temperature bubbles of tea, etc., to help readers use the thermos cup correctly and protect their health.
