When it comes to eating healthy, navigating the nutrition labels on food packaging can be overwhelming. With so many details to consider, how can we easily identify which foods are better for us? Enter the Nutri-Score, a straightforward nutritional rating system that simplifies the process of choosing healthier options.
What is the Nutri-Score?
The Nutri-Score, also known as the 5-Colour Nutrition Label or 5-CNL, is a color-coded system designed to provide a clear and simple indication of the nutritional quality of food products. It rates foods on a scale from A to E, with corresponding colors from green to red:
A (Green): Indicates the healthiest options.
E (Red): Indicates the least healthy options.
This system aims to help consumers make more informed and healthier food choices at a glance.
How Was the Nutri-Score Developed?
The Nutri-Score was introduced by the French government in March 2017, following a comparison with several other proposed labels. It was developed by Santé Publique France, the French public health agency, based on the work of Serge Hercberg from Sorbonne Paris North University. The development process also involved the Agency for Food, Environmental and Occupational Health and Safety (ANSES) and the High Council for Public Health (HCSP).
The Nutri-Score is based on a nutrient profiling system originally derived from the United Kingdom Food Standards Agency’s nutrient profiling system (FSA score). This system, sometimes referred to as “model WXYfm,” was evaluated by Professor Mike Rayner in 2005. Since its inception, the Nutri-Score has been recommended by several European Union countries, the European Commission, and even the World Health Organization.
How Does the Nutri-Score Work?
The Nutri-Score calculation is based on the nutritional contents of a food product. The system evaluates both positive and negative nutritional components to determine the overall score. Here’s a breakdown of the scoring process:
Negative Points (N): These are based on the content of nutrients considered problematic when consumed in excess. These include:
High energy density (calories) per 100 g or per 100 ml
High sugar content
High content of saturated fatty acids
High salt content
Positive Points (P): These are based on the content of beneficial nutrients and ingredients, such as:
Fruits, vegetables, nuts, and legumes
Fiber content
Protein content
Healthy oils (rapeseed, walnut, and olive oil)
Total Score Calculation: The Nutri-Score is determined by subtracting the negative points (N) from the positive points (P). In most cases, this simple calculation (N-P) is sufficient, but there are special cases where additional rules apply.
Based on the total score, the food is assigned a Nutri-Score ranging from A to E, which is then displayed on the product packaging in a color-coded label.
Why is the Nutri-Score Controversial?
Despite its growing popularity and recommendations by various health organizations, the Nutri-Score has sparked some controversy, particularly in certain European Union countries. The debate mainly revolves around the methodology used to compute the scores, which some argue may oversimplify the nutritional value of foods or fail to adequately consider cultural dietary practices.
For example, foods traditionally considered healthy in some regions, like certain cheeses or olive oils, might receive lower Nutri-Scores due to their fat content, despite having other health benefits. Critics also argue that the system does not account for portion sizes or the context in which foods are consumed.
Conclusion
The Nutri-Score is a step toward making healthier food choices easier for consumers. By providing a simple and intuitive way to understand the nutritional quality of foods, it aims to help people make better dietary decisions. However, like any system, it is not without its flaws and continues to be refined and debated within the global health community.
As the Nutri-Score becomes more widely adopted, it is important to use it as one of several tools for guiding healthier eating habits, always considering the broader context of overall diet and lifestyle.
