Overview
This study aims to conduct a randomized clinical trial to measure the effects of a 3-month daily mixed-soy food intervention vs. a control group receiving isocaloric foods on reproductive hormones, body composition, metabolic risk, fecal microbiota, and cognition among 8-11-year-old children. Additionally, this study will assess soy food intake immediately following participation in the clinical trial to determine changes in soy food acceptance in children.
Description
The central hypothesis is that greater soy isoflavone consumption does not alter sex steroid levels but is associated with beneficial clinical outcomes of body composition, metabolic health, and gut-brain axis among pre- and early adolescents.
