I’m more amazed at the toxic (no pun intended) comments in this post. It seems HN isn’t a place to voice health theories.
In addition a lot of the speculation assumes something specific to the US where this is a trend in multiple countries, predominantly high income ones[0][1], but this speculation that it might be 'chemicals' is fairly dull to read and adds nothing. Why this cohort specifically? What commonalities are there between countries with an observed increase? If it's diet why would it only impact the younger cohort?

I work with health research doctors and I've too much respect for them to humour "health theories". And they don't tell me how to do my job either.
