    before i knee-jerk react to this, i need to know:

    • source? give me a link at minimum, preferably a scientific journal since you’re citing “the science” - much else isn’t gonna make the cut here.

    • if this is the case, why did i and my peers have crippling allergies for the entirety of my childhood? we spent tons of time around manure, thousands of hours literally walking in it. we still couldn’t breathe outdoors without getting allergy symptoms.

    edit: also, what does alleged lower incidence of allergies and “other autoimmune issues” have to do with the relation between playing around manure or drinking raw milk, and getting E.Coli infections/dying? those two are quite closely correlated, the “science” also shows that.

      I can’t get deep into the search right now, but you can check the big overviews. It’s called the ‘Hygiene Hypothesis’ and it’s been a topic for quite a while. Some interesting articles that will get you in the general area are about some specific allergens, microbiome influence on allergens, and this one I can’t find a link for right now, but look up the research on Finnish children who became politically separated from their close relatives by a political border (when the USSR and the ‘western world’ became contentious and the flow of people became stymied). That one is particularly interesting because you have three populations: the USSR folks at the border (a rural area), the Finnish folks at the border (a rural area), and the Finnish folks away from the border in the urban areas. If I remember correctly, the Finnish word for autoimmune disorders has literal translation of ‘clean house disease’ or something similar.

      What makes the border research interesting is you have two ‘western medicine’ groups split by the rural/urban divide and a rural ‘other’ category to compare to. I can’t remember if they had issues and couldn’t include the USSR urban group, or if it was too great of a divide genetically/diversity-wise to include to accurately compare without adding a third condition.

        Yeah. Calling bullshit on this.

        I’m the 2nd oldest of 7 kids. That house was never clean. We had all kinds of pets. I would play in the woods, make mud pies, catch weird bugs, eat wild berries and onion grass. I pretty much had the “go outside and play in the dirt to build character” childhood. I’ve got a couple of food allergies and pet dander allergies. My oldest sibling has an auto-immune issue, the ones just after me are pretty healthy, just some minor lactose intolerance, and the two youngest (from my step dad) have a bunch of weird allergies, like potatoes and milk.

        It’s a genetic roll of the dice. The reason why allergies seem more common is because more kids are able to survive anaphylaxis at a young age thanks to modern medicine and quick emergency response times… Like I went through when I spontaneosly developed a severe fish allergy at 4 years old.
