Category I: milk and dairy products
Whether it is heated milk, yogurt or blended milk powder, everything is put in a thermos bottle, which will keep these dairy products in a high temperature state for a long time because of the thermal insulation effect of the thermos bottle. If the temperature is in the high temperature range for a long time, it is easy to deteriorate and bacteria multiply. Light, just some taste changes, serious, will make us food poisoning, diarrhea. Therefore, milk and dairy products must not be put in thermos cups, which is more conducive to our health and the absorption of the nutritional value of milk.
The second category: acidic drinks.
It is not recommended to make small series of lemonade and sour plum soup, as well as strong acidic drinks such as apple vinegar. Everyone uses thermos cups. Because in order to get the best insulation effect, the material of the thermos cup is mostly stainless steel. Although the heat insulation effect of stainless steel is very good, stainless steel is extremely afraid of acidic substances. When holding acidic drinks in thermos cups, it is easy to dissolve some metal components into acidic solutions, which will cause serious harm to our health. So try not to put these acidic drinks in thermos cups. If possible, try to use glass and plastic bottles, which is good for our health.
The third category: carbonated drinks
Speaking of carbonated drinks, many young people love to drink them. However, we all know that carbonated drinks are corrosive to some extent, so if carbonated drinks are filled in thermos cups, it is easy to cause metal corrosion in the cups. Moreover, some harmful metals are easy to appear and dissolve and precipitate in carbonated drinks. How can you be healthy after drinking this poisonous drink? Therefore, for the sake of our health, I hope that everyone will not use thermos cups to hold carbonated drinks, and at the same time try to drink less carbonated drinks, which is more conducive to our health.
The fourth category: Chinese medicine
In order to keep the temperature of traditional Chinese medicine at a suitable temperature, many people use thermos cups to hold traditional Chinese medicine. In fact, this is a very incorrect practice, because in the process of boiling Chinese medicine, many medicinal materials are mixed together, which will dissolve some acidic substances. This will cause some damage and destruction to the inner container of our thermos cup, and will also reduce our efficacy to a certain extent. Yes, it even reacts with the liner, which is harmful to our health. So in order to avoid this situation, try not to put Chinese medicine in a thermos cup.
