I understood that article as there being many bad studies on how much plastics are in our body. But I find it highly unlikely there isn't any plastic in my body, from my toothbrush or chewing gum or water bottle or that old black plastic spatula I fry my eggs with or the air that pushes all kinds of particles into me etc. etc. And studies like your parent comment's https://pmc.ncbi.nlm.nih.gov/articles/PMC12692081/ make it seem likely that they could have some negative effect. So I'm not worried about it, but I also find it a good idea to be cautious (maybe I'll avoid heating food in plastic containers) and for there to be more research into it.
