Outcome Measures

Primary Outcomes (1)

Dietary Fiber Intake
The primary outcome measures the change in participants' daily dietary fiber intake (grams/day) after using the nutrition education mobile app for 6 weeks, compared to baseline and control group levels, using 24-hour dietary recalls and food frequency questionnaires.
Baseline (T0), after three-weeks (T1), after six-weeks (T2), after twelve-weeks (T3)

Secondary Outcomes (7)

Planetary Diet Adherence
Baseline (T0), after twelve-weeks (T3)
Mediterranean Diet Adherence
Baseline (T0), after twelve-weeks (T3)

Intervention

EXPERIMENTAL

Intervention: Participants use the UNIPLATE mobile app, a tailored educational tool designed to promote healthy and sustainable eating. Features: Daily nutrition/sustainability tips, meal planning, recipe suggestions (prioritizing plant-based foods), gamified challenges, and progress tracking. Delivery: 6-week active phase with daily app notifications, followed by 6-week follow-up (no notifications). Tailoring: Content adapts to baseline food-related psychobehavioral profiles (assessed via questionnaire). Support: Developed with input from nutritionists, psychologists, and computer scientists (University of Parma).

Behavioral: Digital Nutrition Education Mobile App for Healthy and Sustainable Eating

Control

NO INTERVENTION

Intervention: No app or active intervention; participants maintain habitual dietary behaviors. Monitoring: Completes identical assessments (dietary recalls, biomarkers, anthropometrics) as the intervention group.

Interventions

Digital Nutrition Education Mobile App for Healthy and Sustainable EatingBehavioral

This intervention is uniquely characterized by: Dual Health-Sustainability Focus - Unlike most nutrition apps targeting weight loss, this integrates planetary health metrics (e.g., carbon/water footprints) alongside dietary guidance. Psychobehavioral Personalization - Content is tailored to four predefined user profiles (e.g., "Convenience-Seeker," "Health-Conscious") identified through baseline questionnaires, adapting messaging strategies (e.g., time-saving tips vs. environmental appeals). Biomarker-Validated Outcomes - Unlike apps relying solely on self-reports, efficacy is assessed via objective measures (urinary LC-MS metabolomics, fecal microbiota analysis). Academic Development - Designed by nutrition scientists + AI engineers (University of Parma), with recipes aligned to Mediterranean/Planetary Diet standards

Intervention Model

PARALLEL

Model Details: This is a randomized, parallel-group controlled trial with a 12-week duration (6-week active intervention + 6-week follow-up). Participants (n=60) are university students with low baseline fiber intake, randomly assigned to: Intervention group (n=30): Uses a tailored mobile app (MAPHealthS) with nutrition education, meal planning, and sustainability tips. Control group (n=30): No intervention. Key features: Blinding: Single-blind (outcome assessors may be blinded; participants are aware of group allocation). Data collection: Dietary intake (24h recalls, FFQs), biomarkers (urine/fecal), anthropometrics, and actigraphy (subgroup). Primary outcome: Change in daily fiber intake (g/day). Secondary outcomes: Diet sustainability scores, physical activity, body composition, and environmental impact.
