Microwaving food in plastic moves chemicals such as BPA and phthalates into the food.

Short answer
No, because heat can move BPA, phthalates and other chemicals from plastic into food. Andrew Huberman says to avoid microwaving plastic, while Peter Attia cautions against overstating the wider microplastic scare. Use glass or ceramic. A microwave-safe label means the container keeps its shape, not that no chemicals migrate.
positive partly neutral negative Each researcher and each study counts once per claim, however often they come up.

Microwaving food in plastic moves chemicals such as BPA and phthalates into the food, so don't do it.
Andrew Huberman, on his own show, is the bluntest. His point is mechanical. The BPA, phthalates and plasticizers added to make plastic hard or flexible are not chemically bound to it.
Add heat and they migrate out of the plastic into whatever touches it, your food or water. A microwave does it fast, and a plastic bottle baking in a hot car does the same thing more slowly. "Microwave-safe" is a structural label: it means the container won't melt or warp, not that no chemicals leach.
Mark Hyman classifies BPA, its substitute BPS, and phthalates as endocrine disruptors, chemicals that mimic estrogen, disrupt hormones and promote fat storage. His advice is to limit exposure, especially heating food in plastic. Peter Attia, in a dedicated AMA on microplastics, PFAS and phthalates, confirms the same leaching chemistry, and that heat and fatty or acidic foods increase it.
Attia also calibrates the fear. The widely shared "you eat a credit card of plastic a week" claim is largely debunked, and most swallowed microplastic leaves in stool within a few days. The open concern is the smallest nanoparticles and the hormone-disrupting additives, not a headline number.
The sensible move is the cheap one. Microwave and store hot or acidic food in glass or ceramic, don't leave plastic bottles in a hot car, and stop worrying about what you can't control. Precis sells nothing.
