Pilot Feasibility of Rice Bran Supplementation in Children

Not Applicable

Completed

• Conditions: Dietary Rice Bran Supplementation
• Interventions: Dietary Supplement: Vitamin A; Dietary Supplement: Rice Bran + Vitamin A

• Registration Number: NCT02557373
• Lead Sponsor: Colorado State University

Brief Summary

The purpose of this study is to assess feasibility of rice bran consumption in weaning children and to identify dietary rice bran mediated changes to the stool microbiome and stool metabolome.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Vitamin A	Vitamin A	Randomized participants will receive a one-dose of vitamin A supplementation (100,000 IU) at the beginning of the trial.
Rice Bran + Vitamin A	Rice Bran + Vitamin A	Randomized participants will receive a one-dose of vitamin A supplementation (100,000 IU) at the beginning of the trial plus consume a measured dose of rice bran daily.

Primary Outcome Measures

Name	Time	Method
Number of participants who are compliant to consuming rice bran daily and in amounts provided.	3 months	Record daily rice bran consumption and track compliance to diet intervention by regular visits from local community health workers.

Secondary Outcome Measures

Name	Time	Method
Number of participants with microbial modulations in stool as detected by microbiome sequencing	3 months	Measure the stool microbiome modulation with rice bran consumption for gut health and diarrhea prevention compared to a Vitamin A supplementation alone.
Number of participants with metabolite modulations in stool as detected by Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS)	3 months	Measure the stool metabolome modulation with rice bran consumption for gut health and diarrheal prevention compared to a Vitamin A supplementation alone.
