Hmm, thats a sad read. But I am not buying 'its the industry' in 2026, this is caused by folks who should and could do better but couldn't be bothered. Its also indicated in the article, young people know its junkfood and know long term effects but simply don't care. If wanting to point fingers aim them at society as a whole, junkfood was well recognized problem 10-15 years ago when these kids were being born.
Mine was a quip, but if we want to go deeper: like any phenomenon, it's obviously a combination of cultural, economic, and social factors; but it's hard not to take the marxist view that it's all about the economy when we get bombarded every second by advertising for food, the composition of which is largely dictated by considerations about profit margins. Even pasta is not produced in the same way as 80 years ago, not even from the same ingredients (half the wheat used in Italian pasta now comes from Canada and other places).
