Comparing gut bacteria in infants fed different formulas and breast milk

The Role of Milk Fat Globule Membrane and 2'-Fucosyllactose in the Infant Gut Microbiota

Not applicable Interventional University of Arizona · NCT06059209

This study looks at how different feeding methods, like standard formula, a new formula that mimics breast milk, and breastfeeding, affect the gut bacteria of healthy infants from birth to 4 months old.

What this trial studies

This study compares the gut bacteria of healthy infants fed either a standard infant formula, Enfamil Infant, a new formula designed to mimic breast milk, Enfamil NeuroPro, or breastfed infants. It is a randomized, double-blind, parallel-group study that will analyze fecal samples collected from birth to 4 months of age to assess the impact of these feeding methods on the microbiome. The study aims to determine if the addition of specific components in the Enfamil NeuroPro formula influences gut health similarly to breast milk. Investigators will also evaluate growth parameters and indicators of inflammation and intestinal barrier function.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy term infants whose parents can provide informed consent and complete weekly digital questionnaires.

Not a fit: Patients who may not benefit from this study include premature infants, those born via c-section, or infants with health issues identified at postpartum screening.

Why it matters

Potential benefit: If successful, this study could provide insights into how infant formula can be improved to better support healthy gut development in infants.

How similar studies have performed: Other studies have shown promising results in understanding the impact of infant feeding methods on gut microbiota, making this approach both relevant and potentially beneficial.
