15. Microwave Popcorn
Multiple scientific studies have shown that flavorings such as diacetyl, and other chemicals found in microwave popcorn bags, are unsafe due to the risk of irreversible lung damage.
Between 2002 and 2015, microwave popcorn packaging and diacetyl were eliminated. However, some chemicals are still in use.
Perfluorochemicals are also used in microwave popcorn. They act as nonstick coatings on popcorn bags to keep oil and grease from leaking out. Each microwave popcorn paper bag can contain perfluorochemicals up to 300 microg/kg.
While the popcorn is heating, this chemical will inevitably meld with it. This chemical has been linked to both prostate cancer and pancreatic caancer.
