Can you eat popcorn in pregnancy?

I think what you're referring to here is about store-bought microwaveable popcorn. Microwaveable bags used to microwave ready-made poocorn are coated with fluorotelomers which break down into a substance called PFOA under high heat. It may be directly transmitted to the foetus and cause developmental problems. http://learn.eartheasy.com/2014/12/11-common-foods-to-avoid-during-pregnancy/ If you worried about that you can make your own popcorn using just butter and putting your corn cob wrapped with a paper bag in a microwave.
