The High Fat, Salt and Sugar (HFSS) nutrient profiling model is central to UK regulations governing the promotion and placement of less healthy food and drink products. Brands, retailers, and food manufacturers must understand and accurately calculate HFSS scores to comply with restrictions on advertising and promotions.
In this detailed guide, we’ll break down the whole process of HFSS calculation, what it means, how it’s done, and which products are affected. By the end, you’ll have a precise understanding of how to use an HFSS calculator, interpret results, and optimize recipes accordingly.
Key Takeaways
- The HFSS score determines if a product is classified as “less healthy” under UK regulations.
- It’s calculated by subtracting positive nutrient points (fruit/veg/nuts, fibre, protein) from negative points (energy, saturated fat, sugar, sodium).
- A score of 4+ for foods or 1+ for drinks means the product is HFSS.
- Applies to categories like soft drinks, snacks, ready meals, and desserts.
- Use an HFSS calculator for accuracy and easier reformulation.
What is the HFSS Nutrient Profiling Model?
The HFSS nutrient profiling model, developed by the UK’s Department of Health, assigns a score to food and drink products based on their nutritional composition per 100g. This score determines whether a product is classified as “less healthy” and therefore subject to marketing restrictions.
The model works by awarding points for both negative nutrients (energy, saturated fat, total sugar, and sodium) and positive nutrients (fruit, vegetables and nuts, fibre, and protein). The final HFSS score is the balance of these, indicating the overall healthfulness of the product.
How to Calculate HFSS Score
To calculate your HFSS score, you’ll need a thorough nutritional breakdown of your product. The HFSS model assigns A points for less healthy nutrients and C points for beneficial nutrients. The overall score is calculated by subtracting C points from A points.
Use the calculator below to estimate whether your product is classed as “less healthy” (HFSS) under the UK Nutrient Profiling Model. Choose Food or Drink, then select NPM 2004/05, NPM 2018, or Both to compare results side‑by‑side. All inputs must be per 100g (or per 100ml converted to per 100g for drinks), and the tool will automatically handle common unit swaps like kcal ↔ kJ and salt ↔ sodium. If you’re using the 2018 model, note that it requires free sugars (not total sugars from the label), which typically needs a recipe-based calculation, so treat that score as an estimate unless you have verified manufacturer/recipe data.
