NutriScoreCalculator

The goal of this project is to provide a simple package that can calculate the Nutri-Score based on the formula of 2024.

What is the Nutri-Score?

The Nutri-Score is a nutrition label that converts the nutritional value of products into a simple code consisting of 5 letters, each with its own color. Each product is awarded a score based on a scientific algorithm. This formula takes into account the nutrients to avoid (energy value and the amount of sugars, saturated fats, and salt) and the positive ones (the amount of fiber, protein, fruit, vegetables, and nuts). You can therefore see at a glance which products are recommended and which should be avoided.

The formulars are sourced from: https://www.bmel.de/SharedDocs/Downloads/DE/_Ernaehrung/Lebensmittel-Kennzeichnung/nutri-score-dt-excel-berechnungstabelle.html
