Almonds, Gut Microbiome and Kids
Nutritional Impact of Almond Butter on Gut Microbiome and Cardiometabolic Health in School-Aged Children: A Novel and Timely Pilot Randomized Controlled Trial
This 8-week parallel-arm randomized controlled trial (N=70; ages 6-13) will determine the impact of daily almond butter consumption on gut microbiome composition and function, intestinal barrier integrity, and cardiometabolic health in school-aged children. Participants will be randomized to either a once-daily snack of personalized-portion almond butter (ALB; 16g, Creamy Natural Almond Butter) or an isocaloric nut-free chocolate spread control (CTL; 16g, Cadbury Milk Chocolate), each served on two plain unsalted saltine crackers, added to their habitual diet. The primary outcomes include oro-gut microbial composition and diversity, gut microbial functional capacity and metabolomics (SCFAs, bile acids, amino acid metabolites), and intestinal barrier integrity. Secondary outcomes include fasting cardiometabolic markers, systemic inflammation, appetite-regulatory and metabolic hormones, and sleep-related biomarkers. Feasibility, adherence (weekly logs; serum α-tocopherol), and precision nutrition potential will also be assessed, with stratified analyses by age, sex, BMI, ethnicity, and pubertal stage.
This pilot trial will generate the first multi-omics characterization of almond butter's effects on the gut-immune-metabolic axis in children.

Aktivní komparátor: Ovládat stav svačinu
Skupina kontroly (CTL): Tato podmínka zahrnuje normální dietu doplněnou denně s isocalorickým množstvím bez ořechů, čokoládového rozpětí na bázi rostlinného oleje (Cadbury mléčná čokoláda) také vložená mezi dva obyčejné nesolené slané sušenky (nesolené prvotřídní prémiové saltinské sušenky), se stejným limitem 16G na dva crackery.
Množství čokoládové šíření poskytované denně bude ekvivalentní 20% jednotlivého denního kalorického příjmu každého účastníka.
Tyto kalorické potřeby budou stanoveny pomocí stravovacích pokynů pro Američany (DGA) na základě věku a pohlaví účastníka účastníka

Skupina Control (CTL): Účastníci této skupiny obdrží denní občerstvení sestávající z isocalorického množství bez ořechových, čokoládových rozpětí na bázi rostlinného oleje („Cadbury mléčná čokoláda“), která se šíří mezi dvěma prostými nesolenými sušenky („nesolené prvotřídní spatky“)).
Podobně jako ve skupině arašídového másla bude čokoládová rozpětí omezena na 16 g na dva sušenky, přičemž v případě potřeby jsou poskytnuty další sušenky.

Experimentální: Almond Butter Condition
Participants in the ALB group will maintain their habitual diet supplemented with a once-daily snack of smooth natural almond butter (Creamy Richards 100% Almonds!
Creamy Natural Almond Butter) spread between two plain unsalted saltine crackers (Unsalted Tops Premium Saltine Crackers), with a maximum of 16g of almond butter per two crackers.
The daily portion of almond butter will be individualized to provide 20% of each participant's estimated daily caloric needs, calculated using Dietary Guidelines for Americans (DGA) age- and sex-specific energy requirements.

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