Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose is to assess feasibility of rice bran consumption in weaning children and collect pilot data on gut microbiome and metabolome modulation with rice bran intake for diarrheal prevention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Rice bran is a globally accessible, underutilized food ingredient with an array of beneficial nutrients (e.g. phytochemicals and prebiotics) that promote health and potentially prevent diseases. The investigators will determine if dietary rice bran intake can modulate the infant gut microbiome and metabolome to promote gut immunity for the benefit of preventing diarrheal diseases that increase risk for malnutrition and stunting.

The investigators hope to learn about the feasibility of dietary supplementation of heat-stabilized rice bran in weaning children living in regions with increased susceptibility to diarrhea and malnutrition, and whether or not rice bran consumption can modulate the stool microbiome and metabolome.
