I would take a lot of science with a grain of salt too. Looking at the recent peanut butter allergy studies for example. Original 2016 study used 10 jewish children in Britain vs. 10 jewish Children in Israel. This study caused policy change around the world. Australia went from under 25% to over 80% of people feeding their children peanut butter under the age of 1. It had no discernible effect on allergies to peanut butter at all. They've followed it up with a larger study, 100 jewish kids in Britain vs. 100 jewish kids in Israel to prove out their original theory.

“That trial, involving hundreds of babies under a year old at high risk for developing peanut allergy, established that kids could be protected by regularly eating a popular peanut butter-flavored Israeli snack called Bamba. A follow-up study later showed those kids remained allergy-free even after avoiding peanuts for a year.

Under the new recommendations, published simultaneously in six journals including the Journal of Allergy and Clinical Immunology, all infants who don’t already test positive for a peanut allergy are encouraged to eat peanut-enriched foods soon after they’ve tried a few other solid foods.”

Early exposure seems to be the recommended path.

I get that it's the recommended path, it's been recommended since that first study in Australia and has had zero effect on peanut allergy rates even though # of people feeding peanut butter to their children under 1 has increased significantly.

Honest Q, Is that true? I mean, A) that since this study in 2015 or so, there’s been no decline in the prevalence of peanut allergies in the relevant populations? B) people are in fact submitting their children to disciplined exposure in a significant (enough) quantity?

Huh? I thought very recently that link was established as being real?

Please post a link to the study.

May I ask why you've included the study participants religion even though it doesn't appear in the studies you've cited? (afaik)

From the study[1]: "Several years ago, we found that the risk of the development of peanut allergy was 10 times as high among Jewish children in the United Kingdom as it was in Israeli children of similar ancestry. This observation correlated with a striking difference in the time at which peanuts are introduced in the diet in these countries: in the United Kingdom infants typically do not consume peanut-based foods in the first year of life, whereas in Israel, peanut-based foods are usually introduced in the diet when infants are approximately 7 months of age"

So, the difference in real-world outcomes amongst Jewish populations in different countries inspired this study.
