Don’t choose brightly colored plastic tableware. According to inspections, the release of heavy metal elements such as lead and cadmium in the color patterns of some plastic tableware exceeded the standard. Therefore, try to choose colorless and odorless plastic tableware without decorative patterns. In addition, when purchasing instant noodles, pay attention to the logo on the bottom of the bowl. The logo is “PS” (polystyrene) or “PP” (polypropylene) and you can use it with confidence. The foamed plastic bowl contains foaming agent. After being soaked in hot water, harmful substances in the foaming agent will dissolve out and enter the human body with the food. In addition to being non-degradable, disposable foam plastic lunch boxes also have the above-mentioned problems, so their use is prohibited.
Don’t choose paint chopsticks. Although painted chopsticks are very decorative, they are not desirable from a health point of view. Because paint contains many toxic substances such as lead and cadmium. It is best to choose unpainted bamboo or wooden chopsticks that are in compliance with hygiene standards.
Non-stick pans, rice cookers, etc. are not suitable for dry cooking. On the inner wall of non-stick pans and rice cookers, there is a plastic coating made of polytetrafluoroethylene. When heated to above 400°C, this coating may release the toxic gas tetrafluoroethylene. Therefore, people must not let non-stick pans and rice cookers empty.
Iron and aluminum tableware should not be used together. Although iron tableware is safe, if it is used with aluminum tableware, it will bring greater harm to the human body. Since aluminum and iron are two metals with different chemical activities, when water is present, aluminum and iron can form a chemical battery, and the result is that more aluminum ions enter the food. Therefore, tableware such as aluminum spoons, aluminum shovel, and iron pans are not suitable for use together.
