What It Does

Nutri-Score is a feature that grades the nutritional quality of a dish or food item using a five-letter color-coded scale from A (healthiest) to E (least healthy). It evaluates the balance between positive components (fiber, protein, fruits, vegetables) and negative components (saturated fats, sugars, sodium, energy density). This provides an intuitive, single-score indicator for users and organizations to compare the nutritional healthiness of meals.

When to Use It / Outcomes

You want to evaluate the nutritional quality of a dish or product using an established European scoring model adapted on the LogMeal database.
You want to compare meals based on their nutrient profiles.
You want to offer visual nutrition feedback to users within your app or reports.
Output: JSON with:
- nutri_score_letter → A–E
- nutri_score_value → numerical score (−15 to +40)
- positive_points → contribution from healthy nutrients
- negative_points → contribution from less healthy nutrients
- detailed_components → breakdown of scoring factors (energy, sugar, fat, sodium, etc.)

Feature-Specific Details

Scoring method: Based on the official Nutri-Score algorithm used across the EU and WHO recommendations.
Input data: Derived from the nutritional composition of an intake, dish, or recipe.
Scale:
- A (dark green): Excellent nutritional quality
- B (light green): Good quality
- C (yellow): Moderate balance
- D (orange): Low quality
- E (red): Poor quality
Automatic computation: Included in Nutritional Analysis outputs for both image-based and manual intakes.
Use cases: Can be applied per-dish or per-meal for complete nutritional assessments.

Related Endpoints

Use the following endpoints to retrieve or compute Nutri-Score data dynamically:

GET /score/{imageId}/nutriScore → 🔴 Retrieve Nutri-Score for a recognized dish or image.
GET /score/{date}/meal/{occasion}/nutriScore → 🔴 Retrieve Nutri-Score for a meal on a specific date and occasion (e.g., breakfast, lunch, dinner).
GET /score/{date}/meal/nutriScore → 🔴 Retrieve overall Nutri-Score for a given date (aggregated daily score).

Typical Workflow

Analyze meal or dish: Perform nutritional analysis by uploading any intake based on image, manual input or with any other method.
Retrieve Nutri-Score: Use GET /score/{imageId}/nutriScore for an image or GET /score/{date}/meal/{occasion}/nutriScore for a meal.
Display grade: Present the Nutri-Score visually (A–E color badge) in your UI.
Compare and store: Compare scores over time or between meals; store results with intake data.
Aggregate reports: Use results in nutritional reports and progress dashboards.
