Registered User: Arda (A health-conscious university student looking for affordable, nutritious food)

User Persona

• Name: Arda

2. The system contains at least 500 food items with nutritional details. (Requirement 1.1.1)
3. Content Administrators or Community Moderators are available to review food item submissions. (Requirement 1.8.4)

5. Arda sorts the food database results by protein content (highest to lowest) to compare quinoa with other high-protein grain options.
6. Arda browses the sorted results and evaluates different grains based on their protein content and nutrition scores.
7. Arda searches for "Teff" (a nutrient-dense Ethiopian grain he learned about) but does not find it in the database.
8. Arda decides to propose Teff as a new food item to help expand the platform's offerings.
9. Arda selects "Propose New Food Item" and accesses the submission form.

16. The moderator verifies the nutritional data against reliable sources (USDA database, academic publications).
17. The moderator approves the submission, adding Teff to the food database. (Requirement 1.8.4)
18. The system automatically calculates the nutrition score for Teff using the formula:
    • FoodScore = 0.30 * ProteinZ + 0.30 * CarbQuality + 0.40 * NutrientBalance
