Brief summary

This study evaluates the effect of different complementary foods on the gastrointestinal microbiota of exclusively human milk fed infants.

Detailed description

The introduction of solid foods plays a role in shaping the microbial communities of the gastrointestinal microbiota. This randomized, controlled, single-blinded trial will evaluate the effect of four infant foods (oatmeal cereal, carrot puree, prune puree, beef and gravy puree) on the gastrointestinal microbiota of exclusively human milk fed infants that have not previously consumed solid foods and who are developmentally ready for the introduction of solid foods.

Interventions

Infants will be fed prune puree

OTHERInfant vegetable
