Everyone knows that we should eat clean food. Many people think it’s important and good for health to wash the food before cooking it. However, for some food like eggs, washing can do more harm (害处).
People like to wash the shell (壳) before they cook the egg. They want to make sure there’s no dirt or germs (细菌) on the egg. But they don’t need to do this.
There is a coating (涂层) on the shell of the egg. The coating can help keep the egg away from germs. When factories do the cleaning work, they wash away the coating and put a kind of special thing on the egg shell. It is there to keep germs from coming inside the egg.
“Of course, there are germs on the egg but by washing it you make it worse. The egg shell is porous (可渗透的) , ” says health expert Amy Leigh Mercree. “And this can happen more easily when you use cold water or running water. ”
“So don’t wash eggs—save yourself some time and keep the germs where they are. ” Mercree says.
