[citation needed]. It seems unlikely that fermented foods are not consumed in urban areas at all. I’ve also no idea if other primates consume any fermented foods, but I’d guess probably not.

Do any other primates drink milk after infancy? If not, that’s not really a valid concern in the context of the article.
No. In fact, almost all mammals stop producing lactase once they stop nursing from a mother. Humans are quite rare in that there's a significant population with the mutant "lactose tolerant adult" gene.
I would be curious to see if you took, say, South Korean cities, what the results would be. (Seoul is one of the largest megacities in the world, and kimchi is an extremely common fermented food.)
