What is the nutritional score? A Guide to Nutri-Score

4 min read

According to the World Health Organization, unhealthy diets contribute significantly to the global burden of chronic diseases such as heart disease, cancer, and diabetes. Addressing this, the nutritional score was developed as a standardized, at-a-glance guide to help consumers evaluate the nutritional quality of food products and make informed decisions.

Quick Summary

The nutritional score, primarily known as Nutri-Score, is a front-of-pack label that assesses a product's overall nutritional quality using a five-color, A-to-E scale, simplifying complex nutritional data for consumers.

Key Points

  • Definition: The nutritional score, such as Nutri-Score, is a voluntary front-of-pack label that grades a product's nutritional quality using a color and letter system.

  • Scoring System: Nutri-Score uses a five-tier scale from dark green 'A' (highest quality) to red 'E' (lowest quality) for quick assessment.

  • Calculation: The score is calculated based on an algorithm weighing negative components (calories, sugar, fat, salt) against positive components (fiber, protein, fruits/vegetables).

  • Purpose: It aims to help consumers easily compare similar products and make healthier choices, while also motivating manufacturers to improve product nutrition.

  • Usage: Best used for comparing items within the same food category; should complement, not replace, full nutrition information.

  • Controversy: Criticisms include potential oversimplification and not accounting for processing, micronutrients, or portion sizes.

  • Evolution: The algorithm is regularly updated by a scientific committee to align with current nutritional recommendations.

What is the Nutritional Score, Anyway? An Overview of Nutri-Score

The nutritional score, most widely recognized as Nutri-Score, is a voluntary, front-of-pack (FOP) nutrition labeling system that uses a combination of colors and letters to indicate a product's overall nutritional quality. Adopted by several European countries, the system aims to help consumers quickly assess the nutritional value of food products without needing to fully decipher the detailed nutritional facts panel. The score is based on an algorithm that considers both nutrients to limit (like calories, saturated fats, sugars, and salt) and beneficial components to encourage (like protein, fiber, fruits, and vegetables) per 100 grams or milliliters.

The Scoring System: From Dark Green 'A' to Red 'E'

The Nutri-Score employs a five-level color and letter scale to provide a clear summary of a product's nutritional standing:

  • Dark Green (A): Indicates the highest nutritional quality.
  • Light Green (B): Represents good nutritional quality.
  • Yellow (C): Denotes moderate nutritional quality.
  • Orange (D): Suggests a less favorable nutritional profile.
  • Red (E): Signifies the lowest nutritional quality.

This visual system is intended to guide consumers towards healthier options and encourage manufacturers to reformulate products for better scores. It's crucial to use Nutri-Score to compare items within the same food category, not across different categories like comparing a beverage with olive oil.

How the Nutritional Score is Calculated

The Nutri-Score calculation uses an algorithm that balances points for negative components against points for positive components. The final score, ranging from -15 (best) to +40 (worst), determines the letter grade. The algorithm is slightly adapted for specific categories such as beverages and cheese.

Components considered in the calculation include:

  • Negative Components: Energy (calories), sugar, saturated fat, and sodium.
  • Positive Components: Percentage of fruits, vegetables, legumes, and nuts, along with fiber and protein content.

Updates to the Nutri-Score Algorithm

An independent scientific committee regularly reviews and updates the Nutri-Score algorithm to maintain its scientific validity. Recent updates, for instance, have led to stricter scoring for foods high in sugar and salt while giving better scores to healthier options like whole grains and nuts. These revisions ensure the system aligns with current nutritional science.

Benefits and Controversies of the Nutritional Score

Comparison of Nutri-Score Benefits and Criticisms

Feature Benefits Criticisms
Clarity Simplifies complex nutritional information into an easy-to-understand color scale. Some argue it oversimplifies and can misrepresent certain foods with health benefits but poor scores (e.g., olive oil or cheese).
Informed Choice Helps consumers quickly choose healthier options, especially when comparing similar products. Critics note it doesn't account for total diet, portion size, or individual needs.
Encourages Reformulation Motivates food companies to improve the nutritional quality of their products. Concerns exist that manufacturers might adjust formulations solely to improve the score without genuinely increasing healthfulness.
Scientific Basis Based on a validated system supported by studies linking better scores to better health outcomes. It lacks consideration for food processing level, micronutrients, or additives.

How to Use the Nutritional Score for Healthier Choices

Effectively using the nutritional score, like Nutri-Score, involves more than just selecting products with an 'A' grade. Here's how to make the most of it:

  • Compare Similar Products: Use the score to compare items within the same category, such as different brands of yogurt or bread. Comparing items from different categories is not advisable.
  • Supplement with Other Information: The Nutri-Score is a quick guide. Always consider the full nutrition facts panel and ingredient list for a complete understanding of a product.
  • Context is Key: Foods with lower scores (D or E) can still be part of a healthy diet in moderation. The score provides a snapshot, not a judgment on whether a food should ever be consumed.

The Evolving Landscape of Food Labeling

The implementation and refinement of the nutritional score systems are ongoing, with continuous research and discussion on improvements. The debate about mandatory adoption versus voluntary use persists, though several countries have officially incorporated Nutri-Score. Ultimately, while valuable as a public health tool, the nutritional score is most effective when used by consumers as part of a broader approach to making informed dietary choices.

Conclusion

Understanding what is the nutritional score, particularly systems like Nutri-Score, provides consumers with a valuable tool for making informed food choices. These color-coded labels offer a quick assessment of a product's nutritional quality, aiding in the comparison of similar items. Despite some limitations and ongoing debate, the nutritional score serves as an important public health initiative aimed at improving dietary habits and encouraging manufacturers to enhance product nutrition. When used thoughtfully, alongside other nutritional information and within the context of a balanced diet, the nutritional score can be a powerful guide towards healthier eating.

Frequently Asked Questions

In Europe, the most common nutritional score system is the Nutri-Score, a voluntary front-of-pack label that uses a color-coded letter scale (A-E) to rate a product's overall nutritional quality.

A product's Nutri-Score is calculated based on an algorithm that balances points for beneficial nutrients like fiber and protein against points for less favorable nutrients such as calories, saturated fat, sugars, and salt, per 100g or 100ml.

No, the Nutri-Score is designed for comparing products within the same food category (e.g., comparing different breakfast cereals). It should not be used to compare items across different categories, as this can be misleading.

No, the Nutri-Score is a voluntary labeling system for food manufacturers in participating countries, such as France, Belgium, and Germany, who choose to display it on their products.

No, the Nutri-Score algorithm assesses the product based solely on its core nutritional composition per 100g/ml. It does not factor in other qualities like the degree of processing, organic status, or presence of additives.

Critics point out potential flaws, including the system's oversimplification of complex foods, its inability to factor in processing or portion sizes, and concerns that it may unfairly penalize certain products deemed healthy, like olive oil.

No. A lower score simply indicates a less favorable nutritional profile compared to similar products and suggests it should be consumed in moderation or less frequently as part of a balanced and varied diet.
