Ref what I wrote on https://news.ycombinator.com/item?id=17017920 :
"As a Norwegian, when I visited Boston in 1999 for an Allaire dev conference I saw more grossly fat / obese people in the _hour_ spent switching flights at Newark airport than I had in my (then) home country in the preceding year. I was really taken aback."
I never got my now 7y son into juices etc and Coke products are generally banned in our home. He has a very healthy body weight, so that's one fewer thing he has to worry about whilst growing up.
