Abstract
Similar dietary isoflavone intakes need not generate similar metabolite exposures. Gut microbiota-dependent conversion of daidzein to S-equol offers a plausible, incompletely characterized modifier of pediatric endocrine responses. Pediatric observational data suggest that urinary equol may modify associations between soy intake and pubertal timing, although causality and a fixed producer phenotype have not been established. We propose treating equol-producing capacity as a developmentally dynamic metabotype and testing it through repeated functional phenotyping. Receptor-selective effects on pubertal signaling and interactions with iodine-dependent thyroid physiology remain hypotheses with unknown clinical direction. Prospective studies should integrate diet, functional metabolism, developmental stage, iodine assessment and endocrine outcomes. Current evidence does not justify equol-based dietary restriction or routine clinical testing in healthy children.
