What is Reference Intake (RI)?
RI, or Reference Intake, is a set of standardized nutritional guidelines used on food labels, primarily in the UK and European Union. It replaced the term Guideline Daily Amount (GDA) and is designed to provide consumers with an easy-to-understand reference point for their daily diet. Essentially, the percentages of RI you see on a packet tell you how much a single portion of that product contributes to an average adult's recommended daily intake of energy, fat, sugars, and salt.
The Standard RI Values
The RI values are based on the requirements for a moderately active adult woman consuming 2,000 kcal (8,400 kJ) per day. It's important to remember these are guidelines, not rigid targets, and individual needs can vary based on age, gender, and activity level.
Here are the established Reference Intakes for key nutrients for the average adult:
- Energy: 2,000 kcal / 8,400 kJ
- Total Fat: 70g
- Saturates (Saturated Fat): 20g
- Sugars (Total Sugars): 90g
- Salt: 6g
How to Read and Interpret RI on a Food Label
Reading an RI label is straightforward and provides a quick snapshot of a product's nutritional profile. You will typically find the information presented in a chart format on the back of the package, or in a simplified format on the front.
- Locate the RI information: Look for the table on the back of the package, often labeled "Nutrition Information." On the front, you may see a simplified, 'at-a-glance' summary, sometimes with color coding.
- Check the serving size: RI percentages are often calculated per serving. Be mindful of the manufacturer's suggested serving size, as it may be smaller than the portion you typically consume. For example, if a label lists a serving as one biscuit but you eat three, you will need to triple the RI percentages listed.
- Use the percentages: The percentage figure shows you the proportion of your daily RI that a single serving of that food provides. A product with a 50% RI for sugar means one portion gives you half of the recommended daily intake for sugar.
- Use it as a comparison tool: RI allows you to easily compare different products. If you are choosing between two similar brands of cereal, you can compare the RI percentages side-by-side to see which is lower in fat, sugars, or salt.
Understanding Traffic Light Labeling
In some regions, RI information is combined with a voluntary color-coded "traffic light" system, making it even easier to interpret at a glance.
- Red: Indicates a high amount of a specific nutrient (e.g., fat, sugar, salt). Foods with red labels should be consumed less often and in smaller amounts.
- Amber: Signifies a medium amount of a nutrient. These foods are okay to eat most of the time as part of a balanced diet.
- Green: Means a low amount of a nutrient. Products with more greens are generally considered the healthier option.
Comparison: RI (EU/UK) vs. Daily Values (US)
While RI is used in Europe, the United States uses a different system based on Daily Values (DV). Both serve a similar purpose but have different reference values and are regulated by different bodies.
| Feature | Reference Intakes (RI - EU/UK) | Daily Values (DV - US) |
|---|---|---|
| Basis | European Food Safety Authority (EFSA) and EU Law | U.S. Food and Drug Administration (FDA) |
| Reference Person | Average adult woman, 2000 kcal diet | Average adult and children 4+, 2000 kcal diet |
| Nutrients | Energy, fat, saturates, sugars, salt, protein | Total Fat, Saturated Fat, Cholesterol, Sodium, Total Carbohydrate, Dietary Fiber, Sugars, Protein |
| Vitamins/Minerals | Often listed as % Nutrient Reference Value (NRV) | Often listed as % DV |
| Primary Goal | Provides guidance for a balanced daily intake | Provides a standard for comparison across products |
| Labeling | Often combines with voluntary traffic light system | Standardized Nutrition Facts Panel |
Conclusion: Making Informed Choices with RI
In conclusion, RI is a powerful tool for navigating the complexities of nutritional information on food packaging. By understanding that RI stands for Reference Intake and represents a guide for an average adult's daily intake, you can more confidently assess how a food product fits into your overall diet. While it is not a personalized health recommendation, it provides a valuable benchmark for comparing products and making healthier choices. Whether you are aiming to reduce sugar, lower your salt intake, or simply monitor your overall calorie consumption, the RI percentage is a simple, effective piece of data to help you on your way.

A Quick Checklist for Using RI:
- Read the percentage of the RI, not just the raw nutrient value.
- Pay close attention to the listed serving size, and adjust your calculation if you plan to eat a larger portion.
- Use the traffic light colors, if available, as a quick guide for high (red), medium (amber), and low (green) nutrient content.
- Remember that RI is a guide for the average person, not a personal target, so tailor your food choices to your own health and lifestyle needs.
- Compare the RI percentages of similar products to help you choose the healthier option.
By following these simple steps, you can turn the confusing numbers on a food label into actionable information that supports your healthy eating goals.
