3. Microwave popcorn
There’s a triple whammy here – the butter flavoring used in many microwave popcorn brands releases diacetyl, a known toxin, when cooked. Next, the perfluorooctanoic acid that lines the bags themselves is carcinogenic. And finally, popcorn producers are not required to report whether or not their kernels are GMO.
Alternatives – Buy organic kernels and pop them in an air popper or on your stove.
