I'm talking about research, but in particular research testing potential interventions.
There has been a fair amount of research (but no solid consensus) on why allergy rates are increasing.
But AFAIK there have been fairly few attempts to try to use any of those competing hypotheses to devise preventive treatments whose effectiveness could be tested experimentally.
There is actually pretty compelling evidence. Enough so that the AAP reversed its guidelines in 2017: https://publications.aap.org/aapnews/news/12250/New-guidelin....
Where I live it's advised to introduce peanuts early to kids (before 8 months) because of this research
