Study Overview
Brief Summary
The goal of this clinical trial is to learn if Front-of-Pack labels, namely Nutri-Score and NutrInform Battery, work to improve adherence to the Mediterranean diet among healthy Italian adult participants. It will also learn about the label's ability to increase nutritional knowledge and participant's response in terms of orthorexic behaviour. The main questions it aims to answer are:
- Does FOP nutritional labels work to guide participants' food choices towards healthier diets?
- Do they increase participants' nutritional knowledge?
- To what extent are they related to obsessive focus on healthy eating, such as orthorexia nervosa? Researchers will compare the labels to a no label condition (in which participants were only given a conventional nutrition education flyer) to see if labels work to improve healthiness in individual diets.
Participants will:
- Complete an initial questionnaire's battery
- Use the assigned FOP label every day for 1 month to orient their food choices
- Answer to final questionnaires

Outcomes
Primary Outcomes
Adherence to the Mediterranean diet
Time Frame: 30 days
The adherence is measured with the PREDIMED (PREvención con DIeta MEDiterránea) PLUS questionnaire adapted for the Italian population. The questionnaire asks about the frequency of consumption of traditional Mediterranean food (daily or weekly) by defining the portion size, or asking about the use of food with "yes or no" options, or identifying preferences between different food options. Possible values range from 0 to 17. Higher values correspond to a higher adherence.
Secondary Outcomes
- Nutrition Knowledge(30 days)
- Orthorexic behaviour(30 days)
