Completed

• Conditions: Infant Development
• Interventions: Other: Placebo Powder; Other: Blueberry Powder

• Registration Number: NCT05006989
• Lead Sponsor: University of Colorado, Denver

Brief Summary

The objective of this project is to investigate the effects of blueberries on gut microbiota, inflammation and innate immunity in breastfed infants during early complementary feeding (\~5 to 12 months of age).

Arm && Interventions

Group	Intervention	Description
Placebo Group	Placebo Powder	Participants will be provided placebo powder to be consumed.
Intervention Group	Blueberry Powder	Participants will be provided pre-made whole blueberry freeze-dried powder to be consumed.

Primary Outcome Measures

Name	Time	Method
Infant Growth (Length)	Over 7 months	Measured in cm
Infant Growth (Weight)	Over 7 months	Measured in kg
Gut Microbiome Composition Analyzed using 16S rRNA Amplicon Sequencing	Over 7 months	16S rRNA amplicon sequencing is used to profile taxonomic makeup of fecal specimens. Within the gut microbiome composition, microbial diversity will be summarized using common ecological measures (Good's coverage, Sobs, and Shannon alpha diversity).
Dietary Intake	Over 7 months	3 day dietary recall with results generated by NDSR software

Secondary Outcome Measures

Name	Time	Method
Blueberry-Specific Food Signatures (Compounds) as Assessed by Metabolomics Analysis	Over 7 months	Metabolomics analysis (nutri-metabolomics) is used to identify and validate food-derived biomarkers that may be classified as biomarkers of intake and/or biomarkers of effect, both of which can be linked to health indicators.
