HFSS Calculator
This is a guide that will show you how to access and use the Erudus HFSS Calculator in your Erudus Manufacturer account.
What is the HFSS Calculator?
The HFSS Score Calculator is an essential tool for assessing whether a food or drink product is classified as High in Fat, Sugar, or Salt (HFSS) according to the UK government's Nutrient Profiling Model (NPM). This model is used to identify products considered "less healthy" and thus subject to restrictions on promotions and placement in certain physical and online marketplaces.
The calculator automates the complex scoring system developed by the Department of Health to give a single numerical score, based on the product's nutritional composition per 100g/ml.
