NutriData - Product Nutrition Analyzer for REWE, Amazon & Mercadona

Description

Analyzes nutrition information for products on supported online shops. (REWE, Amazon & Mercadona) NutriData adds nutrition metrics to grocery products on REWE, Mercadona and Amazon, so you can compare products by protein per euro, protein per calorie and overall nutritional value while you shop. SUPPORTED SHOPS • REWE (rewe.de): product pages, search results and category pages • Mercadona (tienda.mercadona.es): product pages, search results and category pages • Amazon.de and Amazon.co.uk: product pages and search results, wherever Amazon lists the product's nutrition facts ON PRODUCT PAGES • NutriScore, a protein-focused score (see below) • Protein per € (or £) • Protein per 100 calories • Protein to carb ratio • Nutrients per 100 g: calories, protein, carbs, fat, saturated fat, sugar, fiber • Color-coded values, from red to green ON SEARCH AND CATEGORY PAGES • The same metrics on every product card • Sort the list by NutriScore, protein per €, protein per 100 calories, protein to carb ratio, protein or fiber (high to low), or by carbs, fat, saturated fat, calories or sugar (low to high). Sorting works on REWE and Mercadona. SETTINGS Turn each shop on or off, sort search results by NutriScore automatically, or hide the metric cards on search pages. WHAT IS NUTRISCORE HERE? It is not the official Nutri-Score (A–E). NutriData's NutriScore ranks food by protein density and value: it combines protein per 100 calories (weighted more) with protein per euro, adds up to 15% for fiber, and takes off up to 50% for saturated fat and up to 40% for sugar beyond the first 5 g per 100 g. When a label leaves fiber out, NutriData estimates it from the energy the other nutrients don't account for. Higher is better. ABOUT THE DATA • Mercadona nutrition comes from a dataset bundled with the extension (about 2,400 products), so some Mercadona products show no metrics. • On REWE product pages, NutriData sends the product's public details (name, brand, price, nutrition values, category) to protein-index.mohamed3on.com to keep its public protein index up to date. No personal data or identifiers are sent. NutriData is open source: https://github.com/Mohamed3on/NutriData
