Frequently Asked Questions
How is the Processing Level Index calculated?
The Processing Level Index (PLI) is calculated based on multiple factors including the NOVA classification, number and types of additives, presence of highly processed ingredients, nutrient profile outliers, and processing techniques. Visit our Processing Levels page for detailed information about our methodology.
How can I suggest a product to add?
We welcome product suggestions from our community. You can contribute directly to the Open Food Facts database, which is our primary data source. Simply visit their contributor page to add new products or update existing ones. Include as much detail as possible, including the product name, brand, ingredients list, barcode, and any other relevant information. Our system regularly syncs with Open Food Facts to incorporate new products.
Where does your data come from?
Our data is primarily sourced from Open Food Facts, a collaborative, free and open database of food products from around the world. We supplement this data with our own research and analysis to provide the most accurate information possible. Visit our Data Attribution page for more information.
What makes a food "ultra-processed"?
Ultra-processed foods are industrial formulations typically made with five or more ingredients, including substances not commonly used in home cooking (such as hydrogenated oils, modified starches, and protein isolates), flavor enhancers, and cosmetic additives. These foods often undergo multiple processing steps and contain little to no whole foods. On our scale, foods with a Processing Level Index of 7-10 are considered ultra-processed.
How can I find healthier alternatives to ultra-processed foods?
Our Alternative Finder tool allows you to search for any product and discover healthier, less processed alternatives. Simply enter a product name, select it from the results, and browse through the suggested alternatives with lower processing levels. You can filter alternatives by category and maximum processing level to find options that best suit your needs.
How often is the database updated?
We update our database regularly with new products, brands, and ingredients. Major updates occur monthly, with smaller updates and corrections happening more frequently. We also update our processing level calculations as new research and methodologies become available. If you notice any outdated or incorrect information, please let us know through our contact form.
