History is full of huge disasters where absence of proof of negative effects was seen as proof of absence of negative effects. PFAS are such an example. There are already proven negative effects, many correlations are probable causations because we have good explanations like endocrine disruption for them, and worst of all bioaccumulation means that we cannot turn the clock backwards and all the more reason to use the precautionary principle.
All chemicals should be considered dangerous without any other knowledge. Coevolution of humans with chemicals (which has a big overlap with “natural” in contrast to synthetic chemicals) is just a prior that makes danger less likely.
Yeah... I'd love to see a "reset" to foods that were generally available 150 years ago. Before industrialized foods were broadly available. Meat, Eggs, common veg, and pre-gmo grains and legumes. And kind of start over. I understand modern farming allows the world as it is to be fed... but there's plenty of room for states/countries that are able to financially to try to do much better.
