I've seen a bunch of sides of it in the US. In the midwest where I grew up parts of my family
required children to drink a glass of milk because the milk-industry propaganda at the time said it was important for kids to drink a bunch of milk for bones and growth and other stuff that was never true and was known to never be true.
But we didn't have the internet yet, so how do you fact check it? The TV said so.
I do see fewer people interested in milk as you go younger here, I think that once it was more broadly understood that milk is marginal the pressure to drink it was gone but there was still some cultural kind of urban legend nonsense that is really hard to get rid of in a society that doesn't trust experts. Which I can't blame anyone for if we're talking about nutritional experts because anyone alive for more than twenty years has seen them flip their opinion on at least a quarter of food types.
It is notable that in that part of my family, half the kids ended up lactose intolerant and still are frustrated about their parents for making them sick all the time as kids by requiring them to drink something they didn't want to drink anyway.
I liked chocolate milk because who doesn't, but after someone for the first time pointed out that it's kinda weird for humans to drink milk intended for calves (maybe I was 13 or 14?) I pretty much just stopped drinking it because it just wasn't that good anyway and now I had an excuse. My brother and mother are both lactose intolerant, it turns out.
I think a lot of people have felt low grade sick their entire lives in the US because they've never gone for long enough without dairy to notice.
