Most of the plant-based protein on the market is sourced from China and seems to be contaminated with high levels of lead - probably due to poor processing controls, and far in excess of natural plant or animal sources.
If it follows the chocolate heavy metal contaminants across brands, it’s likely the machinery used to grind things.
Unfortunately Chinese manufacturers have a long history of using harmful fillers in consumables, even for the non-export market so it's hard to tell how much is accidental and how much intentional.
I dunno if I would consider that to be the norm…those people got the death penalty for what they did, after all.
They got the death penalty more for being dumb enough to get caught. Chinese goods - from aircraft parts and concrete to food and clothing have repeatedly been found to have dangerously cut corners and/or inadequately ensured product safety.
The study says they sourced their proteins from “Not Company LTDA”, which seems to be Chilean.
Oh, it's so much worse than that - NotCo (the sponsor of the study, not just the source of the protein) is using an LLM to create plant-based alternatives to animal-based foods, such as milk, burgers, and mayonnaise. And just because they're based in Chile, I wouldn't take that to mean that's where the plant protein is coming from, as they're just the "designers" of these foods, not the manufacturers.
