Microwave Popcorn Bags
Moderate burden — Microwave Popcorn Bags adds a moderate, reducible exposure.
The grease-proof lining of microwave popcorn bags.
The breakdown
Each driver rated 0 (none) to 10 (worst)
Evidence strength: strong · Detox Score = 100 − hazard×4.6 − exposure×3.4 − persistence×2.6, clamped 1–100.
What this means for you
A Detox Score of 46 places microwave popcorn bags in the Moderate band. The persistence rating is the standout concern here — these compounds linger in the body and environment for years. The non-stick lining has historically used PFAS 'forever chemicals' that can migrate into the oil and popcorn when heated. Loose kernels cost less and skip the coating entirely.
