> Because filter bubbles and liking Europe[1] is very fashionable in filter bubbles that are demographically similar to HN and most of HN has a social circle full of similar demographics that they get their food opinions from.
I don't think that's the case. Demographics for cooking and pop nutritionist shows are not comparable to the demographics of HN. The audience of the former is dominated by married, middle-aged women in metro-suburban areas across the United States while the audience of the latter is dominated by unmarried, late-20s, bicoastal, urban-dwelling men. Outside of family relations or significant others, I see little overlap between the two at the individual or social level.
> There are plenty of people who hold middle America in high culinary regard. The rest of the things those people tend to have to say are generally not welcome around here so those people don't hang out here and don't hang out with the kind of people who hang out here so there's little discussion going on between these groups of people.
My complaint is not about a lack of high regard, but lack of objective assessment. Sure, association or lack thereof might have something to do with a lack of commentary on American diets. But it has nothing to do with unqualified undermining of those diets. Such an opinion must have first come out of someone's mouth before becoming an oft-repeated factoid.
If you know of any, what middle American diets are associated with height, longevity, increased musculature, or better overall health and by what standard is this proven?
