1, wok is the safest, cooking is the healthiest, so you can eat it safely. It is recommended to use an iron pot at home.

2. Healthy cooking choices: iron pot > non-stick pot > stainless steel pot > aluminum pot. Wok deserved champion! Remind everyone that after each use, the iron pan should be cleaned and dried immediately, and hung in a cool and ventilated place to dry it to avoid sunlight. If you don't use it for a long time, you'd better coat it with cooking oil to prevent rust.
