Brief Summary

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

The goal of this is parallel arm, randomized clinical trial is to learn and understand the effect of daily smooth peanut butter consumption on gut and metabolic health of children age 6-13. The main objectives are:

Primary Objective: To determine the prebiotic effect of daily smooth peanut butter consumption for eight weeks on gut health, including microbiome-metabolome arrays, gut epithelial/barrier function, and gut transit time, in school-aged children.

Secondary Objective(s)

1. To determine the effect of daily smooth peanut butter consumption for eight weeks on metabolic and inflammatory health markers, and measures of sleep quality in school-aged children.
2. To determine the potential mechanisms and feasibility of incorporating peanut butter into the diets of school-aged children as part of healthy, personalized nutrition.

Research Intervention(s): Researchers compare two groups to see if there really is an effect of daily smooth peanut butter intake on gut and metabolic health. The two groups are:

1. The 1st condition (PB) includes a normal diet supplemented daily with personalized portion of smooth PB, sandwiched between two plain unsalted saltine crackers.
2. The 2nd condition (CTL) includes a normal diet supplemented daily with an isocaloric amount of a nut-free, vegetable oil-based chocolate spread, sandwiched between two plain unsalted saltine crackers.

Study Groups

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

Peanut Butter Condition

Peanut Butter (PB) Group: This condition involves a normal diet supplemented daily with a personalized portion of smooth peanut butter (Creamy Richards 100% Peanuts! Creamy Natural Peanut Butter) sandwiched between two plain unsalted saltine crackers (Unsalted Tops Premium Saltine Crackers). There is a limit of 16g of peanut butter per two crackers. The quantity of peanut butter provided daily will be equivalent to 20% of each participant's individual daily caloric intake. These caloric needs will be established using Dietary Guidelines for Americans (DGA) based on the participant's age and gender.

Group Type EXPERIMENTAL

Creamy Richards 100% Peanuts! Creamy Natural Peanut Butter

Intervention Type OTHER

Peanut Butter (PB) Group: Participants in this group will receive a daily snack consisting of a personalized portion of smooth peanut butter ("Creamy Richards 100% Peanuts! Creamy Natural Peanut Butter") spread between two plain unsalted saltine crackers ("Unsalted Tops Premium Saltine Crackers"). The amount of peanut butter will be limited to 16g per two crackers, but additional crackers will be provided if the personalized portion exceeds this limit

Control Snack Condition

Control (CTL) Group: This condition includes a normal diet supplemented daily with an isocaloric amount of a nut-free, vegetable oil-based chocolate spread (Cadbury Milk Chocolate) also sandwiched between two plain unsalted saltine crackers (Unsalted Tops Premium Saltine Crackers), with the same 16g limit per two crackers. The quantity of chocolate spread provided daily will be equivalent to 20% of each participant's individual daily caloric intake. These caloric needs will be established using Dietary Guidelines for Americans (DGA) based on the participant's age and gender

Group Type ACTIVE_COMPARATOR

Cadbury Milk Chocolate Spread

Intervention Type OTHER

Control (CTL) Group: Participants in this group will receive a daily snack consisting of an isocaloric amount of a nut-free, vegetable oil-based chocolate spread ("Cadbury Milk Chocolate") spread between two plain unsalted saltine crackers ("Unsalted Tops Premium Saltine Crackers"). Similar to the peanut butter group, the chocolate spread will be limited to 16g per two crackers, with additional crackers provided if needed.
