Nearly **35%** of the calories consumed in France come from ultra-processed foods. However, their consumption is linked to an increased risk of obesity, diabetes, cancer, and cardiovascular disease. ![part food upf](https://ewo-upf.org/hubfs/part%20food%20upf.webp "part food upf")   Ultra-processed foods are sometimes not easily identifiable today because they may benefit from “healthy” marketing or even a positive Nutriscore A or B rating. For example, many cereal bars for athletes, vegetable “steaks,” and gluten-free cookies are ultra-processed products. ## “Our mission is to bring transparency and education on the level of ultra-processing in food products.” ## How does ewö work?   The ewö calculator is free. It allows you to calculate the level of ultra-processing in your recipes and products yourself.   [Accès to ewö](https://calculate.ewo-upf.org/en) [Discover ewö methodology](https://ewo-upf.org/hubfs/ew%C3%B6%20-%20page%20A%20propos%20%26%20m%C3%A9thodo%20EN_v202511.pdf?hsLang=en) ![image ewo](https://ewo-upf.org/hubfs/image%20ewo.webp "image ewo") ![Frame 2499](https://ewo-upf.org/hs-fs/hubfs/Frame%202499.webp?width=491&height=369&name=Frame%202499.webp) #### 1. Enter your recip Add the simple or compound ingredients, the processes used (fermentation, extrusion), and the amounts of sugar.  ![Group 2506-3](https://ewo-upf.org/hs-fs/hubfs/Group%202506-3.webp?width=161&height=189&name=Group%202506-3.webp) #### 2. Find out your score The algorithm automatically calculates a score from 1 (very good) to 4 (very poor) based on ultra-processed food criteria.    ![Frame 2501](https://ewo-upf.org/hs-fs/hubfs/Frame%202501.webp?width=491&height=369&name=Frame%202501.webp) #### 3. Improve your recipes Identify areas for improvement (processes, reformulation, substitution) and instantly update the results. ### Explore our examples  No recipe? Concrete examples of formulations allow you to explore the tool.  The calculation rules are explained in the methodology **[available here](https://ewo-upf.org/hubfs/ew%C3%B6%20-%20page%20A%20propos%20%26%20m%C3%A9thodo%20EN_v202511.pdf?hsLang=en)**. #### An independent assessment tool, designed with leading scientists The method used in this simulator is based on a rigorous scientific approach, **independent of any industrial interests**. It was **co-developed with a committee of recognized experts** committed to healthier and more transparent food.  ![Anthony Berthou](https://ewo-upf.org/hs-fs/hubfs/unnamed%20(1).webp?width=400&height=400&name=unnamed%20(1).webp) ### Anthony Berthou Nutritionist, Author, Lecturer, and Teacher for healthcare professionals— Expert in integrative approaches to nutrition for health ![Sabine Bonnot (1)](https://ewo-upf.org/hs-fs/hubfs/Sabine%20Bonnot%20(1).webp?width=432&height=432&name=Sabine%20Bonnot%20(1).webp) ### Sabine Bonnot Expert in sustainable food systems – Member of international One Health networks – President of Planet-Score ![AF DV](https://ewo-upf.org/hs-fs/hubfs/AF%20DV.png?width=608&height=614&name=AF%20DV.png) ### Anthony Fardet Researcher in Preventive Nutrition,  Expert in Human Nutrition - Pioneer in the study of ultra-processed foods  ## Contact-us!
