Does the popcorn machine have lead?

This is a rumor that I have long wanted to crush. This statement mainly corresponds to the guy who once put the cast iron utensils on the trolley and deflated with a bang. The whole device is actually a horizontal pressure cooker. The reason for lead is that cast iron contains lead, which will volatilize during popcorn, and popcorn will absorb lead, and so on. Regardless of whether trace lead in cast iron can evaporate at that temperature. Let's just say that the popcorn machine imported from the United States with stainless steel plates or the popcorn made directly from the glass bowl in the microwave oven does not exist at all, but the rumors are still endless, which shows that it is difficult to dispel the rumors.

PS。 In the United States, people have always regarded popcorn as junk food, but now nutritionists who use antioxidant content to measure food health have found that popcorn has high antioxidant content and turned it into healthy food, which is really confusing.
