Brief Summary

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

The objective is to investigate the effect of walnuts on gut microbiota, inflammatory markers, atopic dermatitis status, and indices of allergy outcomes in breastfed infants during early complementary feeding.

The three primary aims include:

Aim 1: Evaluate the effect of walnut consumption on gut microbiota structure and function, inflammation, atopic dermatitis, and allergy outcomes.

Aim 2: Evaluate the impact of walnut consumption on infant growth trajectories and risk of overweight.

Aim 3 (exploratory): Identify walnut-specific food signatures that are associated with gut microbiota and immunity biomarkers using a novel nutri-metabolomics technique.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

The walnut group

The intervention group will provide 10g of walnuts daily to their infant for 7 months.

Group Type EXPERIMENTAL

Infant walnut intake

Intervention Type OTHER

The intervention group will receive walnuts at 10 g/day, and the control group will be advised to avoid walnuts/tree nuts during the intervention. The purpose of this research is to learn more about how walnuts as a first food in infants impact immunity and the development of bacteria living in your baby's gut.

Control Group

The control group will be asked to limit walnuts and tree nuts.

Group Type NO_INTERVENTION

No interventions assigned to this group
