Don’t take our word for it. Here’s every fact on this site, with its evidence grade, its caveats, and a link to the source, so you can check us.
We start you on the strong ones: findings that have been replicated or come from one large, well-controlled study. Moderate and weak facts are here too, labeled for what they are. Use “Link to this fact” to share a single card.
Children and pregnancy / Review of other studies
US dermatology guidance recommends including aluminum in baseline allergy patch testing for children, given a high prevalence of aluminum allergy in children and early-life exposure to aluminum through childhood vaccines.
Weak evidence: A single-sentence guidance recommendation in a narrative review, not new pediatric data; the review does not report a pediatric aluminum-allergy prevalence figure itself.

Children and pregnancy / Other evidence
Skin tape-strip tests at about 2 months of age picked up differences before eczema appeared: in one Korean birth cohort, lower protein-bound ceramide plus higher TSLP, IL-13 and 26:1 sphingomyelin gave an odds ratio above 50 for later eczema, and a different marker set reached up to 101 for later food allergy.
Weak evidence: One cohort; a Danish finding (low phytosphingosine) was not replicated by two others; no confidence intervals given; the author says verification across ethnicities is needed.
