Early in the morning, when you are in a hurry to go out, you can casually put the freshly brewed hot tea or a few red dates into the thermos cup, hoping to enjoy the warmth and nourishment at any time during the day. This convenient Xi has become a part of many people's daily lives. However, hidden behind this Xi may be a series of health risks that we know little about.
The topic of "making tea or jujube in a thermos cup may be harmful to health" has sparked a heated discussion on social media. Some experts point out that brewing tea leaves or red dates in a thermos cup for a long time may lead to some unexpected health problems. These problems involve not only the changes in the beverage itself, but also the chemical reaction of the thermos cup material under high temperatures.
In this article, we'll delve into the science behind this everyday Xi. We will answer some key questions: Is it really harmful to make tea in a thermos cup? What will be the effect on our body if we do this for a long time? Is the material of the thermos cup also a factor we need to consider? Through scientific analysis and expert advice, we hope to provide you with a healthier and wiser life choice. Let's uncover the truth behind this daily Xi and ensure that every day is off to a healthy, energetic start.
Thermos cup tea: convenience or hidden danger?
In today's society, thermos mugs are popular due to their convenience, especially when brewing tea. However, this Xi may hide hidden risks.
Changes in the chemical composition of tea leaves at high temperatures
A thermos mug can keep the water warm for a long time, but that's not always a good thing. Tea contains a variety of chemical components such as catechins, caffeine, and tannic acid. These components can change under constant high temperatures. For example, catechins may be converted to other compounds at high temperatures, and the health benefits of these compounds are not yet fully understood. Additionally, persistent high temperatures may increase the concentration of certain components in tea, such as caffeine, which is not good for heart health, especially for people with heart disease.
The possibility of heavy metal release
Another problem is the thermos cup material itself. Some stainless steel thermos cups may release trace amounts of heavy metal elements, such as nickel and chromium, at sustained high temperatures. These elements are usually harmless in everyday life, but if ingested for a long time, they can have adverse health effects. Heavy metal accumulation can lead to a variety of health problems, including kidney and nervous system damage.
Practical case studies
Practical cases show that the incidence of certain health problems in people who use thermos cups to make tea for a long time is slightly higher than that of regular tea drinkers. Although these cases cannot directly prove the causal relationship, they are enough to attract our attention and further research.
How to use a thermos cup to make tea safely
Choose a reliable quality thermos cup to ensure that the material is safe and harmless
Avoid using a thermos cup for a long time to make tea, especially if you don't need to keep it warm for a long time.
Replace the tea leaves regularly to avoid over-steeping the tea leaves in a high-temperature environment.
In summary, although the thermos cup brings convenience to our lives, we need to be aware of the above potential risks when using them. By taking proper precautions, we can minimize these risks and enjoy a healthy tea drinking experience.
The hidden dangers of soaking jujube in a thermos cup are revealed
Red dates, as an ingredient that is generally believed to be good for health, are often used to soak in water. However, when jujube meets thermos cup, things may not be so simple. This section will explore in detail the health problems that may arise from soaking jujubes in thermos cups.
Nutrient changes at high temperatures
In a prolonged period of high temperature, some beneficial components in jujubes, such as vitamins, may be degraded. In particular, vitamin C is easily destroyed under high temperature and water immersion conditions, thus reducing the nutritional value of jujubes.
Prolonged high temperatures may also cause structural changes in certain components, resulting in the formation of some substances that are not good for health. For example, the natural sugars in jujubes may produce trace amounts of harmful substances at high temperatures.
The jujube interacts with the thermos cup material
Vacuum cups of different materials may release harmful substances to the human body in a long-term high temperature environment. For example, some plastic products may release harmful substances such as bisphenol A at high temperatures, while stainless steel cups may release trace metal ions.
The acidic components of jujube may react with the cup material, accelerating the release of this harmful substance.
Microbial problems with prolonged soaking
Soaking jujubes in a thermos cup for a long time, especially if the water is not changed frequently, may provide a suitable environment for the growth of microorganisms. This can lead to the growth of bacteria or mold, which in turn can affect the safety of drinking water.
Practical advice
Consider soaking jujube in room temperature water, or choose the right temperature and time to soak it, and avoid soaking it at high temperature for a long time.
Choose high-quality, safe material thermos cups, check and replace them regularly.
Ensure good hygiene Xi and clean the thermos cup regularly to avoid microbial growth.
Be wary of hidden risks: the material of the thermos cup and your health
When discussing the health effects of thermos cup materials, we first need to understand the two materials commonly used in thermos cups: stainless steel and plastic. The purpose of this section is to reveal the potential health risks that these materials can pose in everyday use.
Potential problems with stainless steel thermos mugs
Stainless steel is a common material used to make thermos cups. It has the advantage of being strong and durable, but at high temperatures, stainless steel may release trace amounts of metallic elements. While most of the time these metals are not enough to cause significant health problems, long-term accumulation can have an impact on the body. In particular, stainless steels containing nickel may have increased dissolution when exposed to hot liquids for extended periods of time, which can lead to allergic reactions in people who are sensitive to nickel.
Chemical dissolution from plastic thermos cups
Another common material is plastic. The main problem with plastic thermos cups is that some types of plastics can release bisphenol A (BPA) or other harmful chemicals at high temperatures. BPA has been shown to interfere with the endocrine system in humans, especially when exposed to high temperatures for long periods of time. Therefore, it is important to choose BPA-free plastics.
Expert advice and selection tips
In view of the above risks, experts recommend that when choosing a thermos cup, give preference to products with high quality standards and good safety performance. For stainless steel thermos cups, it is recommended to choose food-grade materials and avoid storing acidic or alkaline liquids for a long time. For plastic thermos cups, you should choose a product with a "BPA-free" label. In addition, no matter what material you use, you should replace it regularly to avoid long-term use of worn or damaged cups.
