1, soup can be put in stainless steel pot, but it is best not to put the soup in a stainless steel container for a long time.

2. Stainless steel contains heavy metals harmful to human body, such as chromium and nickel. But it will not be used up. Qualified stainless steel products are tested according to national standards to confirm that harmful substances in them will not escape, or the amount of escape is not enough to cause harm to people.

3. However, there is always a difference between the test conditions and the actual conditions, and the amount of harmful substances running out is related to the contact time. So try not to let food contact stainless steel for a long time.
