Assess the degree of ultra-processing of your products

A tool developed with nutrition experts to help professionals (and anyone concerned about food quality) evaluate and reformulate their products and recipes.

Discover the calculation method

Why measure ultra-processing?

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.

A need for transparency and education

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.

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.

The algorithm automatically calculates a score from 1 (very good) to 4 (very poor) based on ultra-processed food criteria.
