Understanding the Updated Nutri-Score Algorithm: An Insight into Nutritional Ranking Systems

A New Chapter in Nutri-Score's Journey

In 2023, the Nutri-Score front-of-pack label algorithm underwent a significant update to ensure better alignment with food-based dietary guidelines (FBDGs) across different countries. The revision aimed to improve the system's ability to accurately categorize and discriminate between products based on their nutritional value. The updated algorithm is a result of a comprehensive comparison of FBDGs and literature reviews against the current Nutri-Score classification. It takes a stricter approach towards products high in components of concern like sugar, salt, and low in favorable dietary components. With these changes, the Nutri-Score continues to strengthen its potential as a complementary public health tool on an international scale.

What Does the Nutri-Score Update Mean?

The Nutri-Score serves as a nutritional indicator, providing consumers with an easy way to compare the nutritional values of products. The system uses a color-coded system to indicate the nutritional value of products, calculated per 100g. In early 2024, the Nutri-Score algorithm was revised to better reflect the actual nutritional value of products, with changes including a greater consideration of sweeteners, sugar, salt, fiber, and unsaturated fats. Producers have been given a timeline until the end of 2025 to update the Nutri-Score on their packaging. The Nutri-Score can be readily found on the packaging of Boni Selection, Okay, and Spar products, and on their websites and apps.

Controversy Surrounding Nutri-Score

Despite the positive developments, the Nutri-Score system has faced criticism. A comprehensive review of studies examining the Nutri-Score pointed out that many of the studies drawing positive conclusions about the system were conducted by its developers or associates. This has led to calls for the system to be evaluated by independent scientific food authorities and real-life evidence of its benefits. Furthermore, it has been noted that Nutri-Score does not function well for some product groups like cheese, potatoes, nuts, and seeds among others. This has led to the suggestion that studies need to be conducted in a complete supermarket range to demonstrate the usefulness of the Nutri-Score.

Are Other Nutritional Ranking Systems Any Better?

While the Nutri-Score has been subjected to criticism, it's essential to note that competing scoring systems also face similar issues. These systems should all be considered as experimental and need to undergo rigorous testing and evaluation by independent bodies. Consumers are, therefore, advised to rely on food-based dietary guidelines rather than front-of-pack logos. In conclusion, while the Nutri-Score and other nutritional ranking systems can be helpful, they are not a substitute for a balanced diet and should be used as a complementary tool to make informed food choices.
