Understanding Nutrition Grades: It's Not Universal
When you see a 'D' grade on a food or beverage, it is a clear indicator that the product is less nutritionally favorable than those with higher grades, such as 'A' or 'B'. However, the precise criteria for assigning this grade differ by region and labeling system. It is crucial to look beyond the letter and understand the system at play to make truly informed decisions for your health.
The Nutri-Grade System in Singapore
Singapore’s Nutri-Grade is a mandatory, colour-coded system specifically for beverages, which is set to expand to other products like cooking oils and sauces. The grading is based primarily on sugar and saturated fat content per 100ml. A Nutri-Grade D label, coloured red, signals that the product contains the highest levels of these ingredients.
- Grade D Thresholds: A beverage receives a Nutri-Grade D if it contains more than 10g of sugar per 100ml, or more than 2.8g of saturated fat per 100ml. If one of these thresholds is met, the beverage is assigned the lowest grade, even if the other nutrient is low. This mandatory label serves as a visual warning, with advertisements for Grade D drinks being prohibited on certain media platforms to reduce their appeal.
- Example: A very sweet, sweetened condensed milk-based tea or a sugary soft drink with milk additives would likely earn a Nutri-Grade D due to its high sugar and/or saturated fat content.
The European Nutri-Score System
In contrast, Nutri-Score is a voluntary, five-level colour and letter system used in several European countries, including France, Belgium, and Spain. It evaluates the overall nutritional quality of a food by assigning a score based on both beneficial and less beneficial nutrients per 100g or 100ml.
- Grade D Thresholds: Nutri-Score assigns a numerical score from -15 (best) to +40 (worst). A score between 11 and 18 results in a Grade D, which is coloured orange. This means the product has a less favourable balance of nutrients. Factors contributing to a higher score (and a worse grade) include high levels of calories, saturated fatty acids, sugars, and salt. Conversely, higher levels of fiber, protein, fruits, and vegetables lower the score.
- Example: Many pre-packaged desserts, some breakfast cereals high in sugar, and certain ultra-processed snacks are examples of products that might receive a Nutri-Score D.
What a 'D' Grade Signifies for Your Health
Regardless of the system, a Grade D is a strong signal to limit consumption. Regularly consuming products with a high grade of D can have significant health implications, primarily due to excessive intake of sugar, saturated fat, or sodium.
Short-term and Long-term Impacts
- Weight Management: High-sugar and high-fat foods are calorie-dense. Frequent consumption can easily lead to a caloric surplus, contributing to weight gain and obesity.
- Blood Sugar Levels: High sugar intake, particularly from beverages, is strongly linked to an increased risk of developing type 2 diabetes. The Nutri-Grade system was developed in Singapore specifically to combat this growing health concern.
- Cardiovascular Health: A high intake of saturated fats and sodium can contribute to health issues like high blood cholesterol and high blood pressure, both major risk factors for heart disease.
- Other Conditions: Excessive sugar consumption has also been linked to issues like dental decay and fatty liver disease.

| Criteria | Sugar and Saturated Fat levels per 100ml | Algorithmic scoring based on multiple nutrients per 100g/ml |
| Mandatory? | Mandatory for C & D grades | Voluntary |
| Purpose | Help consumers identify and limit high-sugar/fat beverages to reduce diabetes risk. | Simplify nutritional information for quick comparison of similar products. |
How to Make Healthier Choices
Being label-savvy means you can make better decisions for your health. When you see a Grade D, consider these actions:
- Treat as an Indulgence: View Grade D products as occasional treats rather than daily staples.
- Seek Alternatives: Actively look for Grade A or B alternatives. For example, choose plain water, unsweetened teas, or low-sugar versions of your favourite drinks.
- Compare Similar Products: Use the grading system to compare items within the same category. If you are buying juice, compare the grades of different brands to find the most nutritious option available.
- Consider the Source: Check if the product contains naturally occurring sugars (like fruit juice) or added sugars and fats. Even naturally high-sugar juices can receive a C or D grade.
Conclusion: Decoding Labels for Better Health
In conclusion, what is nutrition grade D depends on the regulatory system in place, but its purpose is universally to flag products with high levels of nutrients linked to health risks. Whether it’s Singapore’s targeted Nutri-Grade for beverages or Europe’s comprehensive Nutri-Score, a Grade D indicates that a product should be consumed sparingly. By learning to differentiate between these systems, consumers can become more confident and informed, enabling them to make conscious choices that support their overall health and well-being.
