Many thanks for the links, was interesting.

Just by the existence of food standards laws, we know that there must have been food standards problems. Stuff like mayonnaise composition being put into law, must mean that there had been a mayonnaise quality problem or worries at a certain point in time, I just can’t find any specific info on when or what. Those scandals were probably recorded just as well in the news papers of my small country, but if no one writes a new article or paper about the scandal 50+ years after it happened, then that info won’t turn up in an internet search query.

Redheads are probably less genetically diverse than the rest of the population, iirc it’s mostly caused by a recessive gene. So if someone is a redhead, then the chances are high that they share other special genes with other redheads.

Africans on the other hand are more genetically diverse than people from other continents. It’s possible that some African population groups require different levels of medications, but you won’t be able to tell those population groups apart by the color of their skin.

Do you have examples of this stuff happening in continental European countries? I’d love to jump down that rabbit hole.

In the past I’ve read descriptions of systematic bad practices in the industrialized Uk, but I can’t recall reading about similar things happening in other western European countries. Nothing systematic anyhow. I’d image that the french would have had a(nother) revolution if anyone had tried that stuff with their food.
