Clear and accurate nutrition labelling is at the heart of UK food regulations, empowering consumers to make informed dietary choices. One of the most visible elements on food packaging is the Reference Intake (RI), but what does it actually mean, and how should food businesses use it?
This guide breaks down the essentials of RIs, their role in UK food labelling, and how MenuSano helps ensure your labels are always compliant and consumer-friendly.
Key Takeaways
- Reference Intake (RI) values represent daily recommended amounts for energy and key nutrients for the average adult.
- RIs help consumers compare foods and understand their contribution to a balanced diet.
- RIs differ from Nutrient Reference Values (NRVs), which are used for vitamins and minerals.
- Accurate RI labelling is required by UK law for most prepacked foods, and MenuSano automates this process for food businesses.
What Is Reference Intake (RI)?
Reference Intake (RI) is a set of values established to indicate the daily recommended amount of energy and key nutrients for an average adult. RIs are designed to help consumers quickly see how a serving of food fits into their daily diet, making it easier to compare products and manage nutrient intake.
The main RIs used in the UK are:
- Energy: 2,000 kcal
- Fat: 70g
- Saturates: 20g
- Carbohydrate: 260g
- Sugars: 90g
- Protein: 50g
- Salt: 6g
These values are based on an average adult (typically a woman) with moderate physical activity, but for children or those with specific dietary needs, requirements may differ.
Why Are RIs Important on UK Food Labels?
RIs help turn complex nutrient data into something people can interpret at a glance. This supports more transparent decision-making when choosing between similar products or evaluating portion sizes. RIs make nutrition labels more consumer-friendly by:
- Allowing quick comparison between products
- Helping shoppers understand the nutritional impact of portion sizes
- Supporting healthier food choices
- Making complex nutrient information easier to interpret at a glance
- Showing how a food fits into an overall daily diet
Displaying RIs is a legal requirement for most prepacked foods in the UK. Accurate and compliant RI labelling not only satisfies regulatory obligations but also builds consumer trust and strengthens transparency in food packaging.

RI vs NRV: What’s the Difference?
While RIs are used for energy and macronutrients, Nutrient Reference Values (NRVs) are used for vitamins and minerals. For example, iron and vitamin C will display %NRV, while fat and sugar will display %RI.

How Are RIs Displayed on Food Labels?
RIs are usually shown as part of the nutrition declaration table, often alongside per 100g and per serving values. Here’s a typical example:
| Nutrient | Per 100g | Per Serving | %RI per Serving |
| Energy | 400 kcal | 200 kcal | 10% |
| Fat | 10g | 5g | 7% |
| Saturates | 3g | 1g | 5% |
| Sugars | 15g | 7.5g | 8% |
| Salt | 1g | 0.5g | 8% |
How to calculate:
Divide the nutrient amount per serving by the RI, then multiply by 100.
RIs and the Traffic Light Food Labelling System
The UK’s traffic light food labelling system uses RIs to colour-code fat, saturates, sugars, and salt as red, amber, or green. This visual guide helps consumers instantly gauge whether a food is high, medium, or low in these nutrients.

Practical Tips for Food Businesses
Food businesses play a key role in ensuring RI information is clear, accurate, and compliant. Applying best practices helps create labels that support both regulatory requirements and consumer understanding.
- Use the correct RI values as set by UK law.
- Ensure portion sizes are realistic and clearly stated.
- Highlight % RI values to help consumers make healthy choices.
- Keep records of calculations and update them if recipes change.
- Utilize MenuSano to automate RI calculations and generate nutrition labels.
Incorporating these practices helps maintain compliance while improving the clarity and reliability of nutrition information for consumers.
Common Questions About RIs
No, RIs are based on average adult needs. Children, the elderly, and those with specific health conditions may need different amounts.
Yes, for most prepacked foods sold in the UK, RI labelling is required.
There is no specific RI for fibre on standard labels, but health guidelines recommend 30g/day for adults.
