60k kids have avoided peanut allergies due to 2015 advice, study finds

There was a period of a few decades (I guess still ongoing, really) where parents sheltered their kids from everything. Playing in the dirt, peanuts, other allergens. It seems like all it's done is make people more vulnerable as adults. People assume babies are super fragile and delicate, and in many ways they are, but they also bounce back quickly.

Maybe part of it is a consequence of the risks of honey, which can actually spawn camp infants with botulism. But it seems that fear spread to everything.

Sheltering kids from lead paint flakes is certainly beneficial

There's a pretty clear nuance in my post where I was addressing things the immune system can handle. Not poison that accumulates in the body.

Also not true for things the immune system can handle. Many pathogens damage your immune system, not help it, even if you recover.
