Disposable lunch boxes are foamed plastic tableware. If the food is more than 65 degrees, it will precipitate its own toxins and invade the food, just like plastic bags can't withstand high temperatures. Moreover, if the process control is not good during the processing, the toxicity will be even greater. Eating with such a lunch box is equivalent to chronic poisoning. Although the toxicity is weak, long-term use will still cause harm to liver and kidney.

1. Use disposable lunch boxes sparingly at ordinary times. It is better to bring your own lunch box, which is both sanitary and economical.

2. The lunch box made of pure PP is best not to be heated in the microwave oven.

3. The styrofoam lunch boxes used by vendors should be rejected.

4. Some bad manufacturers add plasticizers to facilitate processing. Generally speaking, this plasticizer is soluble in oil. If it is hot oil, it will dissolve more. Therefore, if there is oil in food, a small amount of plasticizer will be dissolved in the oil and then transferred to food. If long-term or excessive exposure to plasticizers, it will have a certain impact on the body. Use disposable lunch boxes to distinguish the advantages and disadvantages, and qualified lunch boxes can be used with confidence. Try to avoid using disposable lunch boxes to contain high-temperature food, fried food, vinegar and cooking wine.

5. How to choose a qualified disposable lunch box: The so-called plastic is a small molecule that constitutes a compound, just like wearing beads. The more times you wear it, the longer it takes, the stronger it is, so there is less plasticizer. If it is transparent or heavy, like that kind of glass, it is translucent when it is flat, but not translucent when it is uneven. Transparency only represents its flatness. Sinking is only the density it presses, and its density has nothing to do with the amount of plasticizer it adds. Therefore, disposable lunch boxes should be strong. Pure PP lunch box floats on the water! Because the density of PP is less than 1, it is lighter than water!

6. The impact of fast food boxes on men will lead to a decrease in sperm count, and long-term exposure of men to plasticizers will lead to a decrease in sperm count. Therefore, men of childbearing age had better not use it.

7. People who often use disposable lunch boxes should eat more fruits and coarse grains: all toxic components in the body can be eliminated in three ways. One is to reduce absorption, the other is to increase elimination, and the third is to reduce harm. Crude fiber food can help the human body absorb harmful substances and excrete them with feces. This way, after the toxin enters the body, it will not enter the blood. There is vitamin C in fruit, which can enhance metabolic function and help to detoxify. Coarse grains are corn, bread, millet and some soybeans.
