Don't Microwave Your Leftovers in Plastic
Heat is exactly when plastic is most likely to migrate into food.
Reheating last night's dinner in its plastic takeout container is a small habit worth breaking.
Heat drives migration
Plastics can leach chemicals into food, and heat speeds that up — so the microwave is the worst time to use them. Even some "microwave-safe" containers are only rated to not warp, not to be chemically inert. Fatty and acidic foods pull more out of the plastic.
The usual suspects
Chemicals like BPA and certain plasticizers can mimic hormones in the body, which is why this gets attention — especially for repeated, everyday exposure.
The move
Transfer food to glass or ceramic before microwaving, and don't reuse flimsy takeout tubs or yogurt cups for heating. Keep plastic wrap off the food too. It's a five-second swap that sidesteps the whole question.
