Timing of complementary food introduction is not associated with inflammatory bowel disease risk: A prospective birth cohort study.

New evidenceepidemiologypediatricmicrobiome
Clinical takeawayNo clinical action yet: this study confirms that timing of complementary food introduction does not influence IBD risk, so no change to current feeding recommendations is needed.
What it foundTiming of complementary food introduction (<4, 4-5, or ≥6 months) was not associated with IBD risk (aHRs 1.04, 0.83, and 1.00, respectively).
ContextThis study refutes prior hypotheses that early complementary feeding might increase IBD risk, aligning with current guidelines that do not link feeding timing to IBD prevention.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
