Visual cues on food packaging, specifically interpretive front-of-pack labels like the Health Star Rating and Multiple Traffic Lights, can subtly influence consumers' perception of appropriate portion sizes for less healthy food items. This innovation & markets research insight is drawn from a 2018 study published in Public Health Nutrition. Using Experimental survey with 1505 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Consider implementing visually interpretive front-of-pack nutrition labels on products, especially those in less healthy categories, to potentially influence consumer portion size perceptions.

Public Health Nutrition · 2018
Key Findings
- 01The Health Star Rating (HSR) led to a small but significant reduction in perceived appropriate portion sizes for pizzas and cornflakes compared to no label.
- 02The Multiple Traffic Lights (MTL) label also resulted in smaller perceived portion sizes for cornflakes.
- 03The Daily Intake Guide (DIG) label, which is less interpretive, showed no significant effect on portion size judgements.
Application
Design takeaway
Consider implementing visually interpretive front-of-pack nutrition labels on products, especially those in less healthy categories, to potentially influence consumer portion size perceptions.
How to apply
When designing packaging for food products, particularly those with a less healthy profile, explore the use of clear, interpretive nutrition labeling systems (e.g., star ratings, color-coded systems) to potentially influence consumer portion expectations.
Project actions
- 01When designing packaging, think about how the visual elements, like nutrition labels, might affect how people use the product.
- 02Consider testing different types of labels to see which ones have the most impact on user behaviour.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large sample size provides robust statistical power.
- +Use of mock packages allows for controlled comparison of different label types.
Limitations
The impact might be smaller in real-world scenarios with actual products and less controlled environments. Consumers might ignore labels or have pre-existing portion size habits.
Reliability & validity
The study's large sample size and controlled experimental design contribute to its reliability and internal validity. However, external validity might be limited due to the use of mock packages and a specific Australian context.
Think critically
To what extent can front-of-pack labeling truly change ingrained consumption habits, or does it merely influence initial perceptions?
Design Principles
"Visual communication on packaging can shape consumer behaviour and perceptions of product use."
Understanding how packaging design impacts consumer behaviour is crucial for product development and marketing. This insight suggests that strategic labeling can be a tool to encourage healthier consumption patterns, even for products not typically considered 'healthy'.
What This Means for Your Design
Putting simple, easy-to-understand nutrition ratings on food packages can make people think they should eat a bit less of it, especially for things like pizza or cereal.
How to use in your project
- 1.Use this research to justify the inclusion of specific front-of-pack labeling designs in your product concept, explaining how it aims to influence user behaviour.
- 2.Cite this study when discussing the impact of visual design elements on consumer decision-making in your design project.

Paragraph starter
The study by Talati et al. (2018) demonstrated that interpretive front-of-pack nutrition labels, such as the Health Star Rating and Multiple Traffic Lights, can lead consumers to judge smaller portion sizes as appropriate for unhealthy foods compared to products without such labels. This suggests that the visual design and interpretability of on-pack information can be a powerful tool in influencing consumer behaviour and promoting healthier consumption patterns.

- What were the main findings?
- The Health Star Rating (HSR) led to a small but significant reduction in perceived appropriate portion sizes for pizzas and cornflakes compared to no label.. The Multiple Traffic Lights (MTL) label also resulted in smaller perceived portion sizes for cornflakes.. The Daily Intake Guide (DIG) label, which is less interpretive, showed no significant effect on portion size judgements.
- What research method was used?

- How strong is the evidence?
- Evidence strength is rated Moderate effect, based on a 2018 journal from Public Health Nutrition.
- What should I do differently in my next project?
- When designing packaging for food products, particularly those with a less healthy profile, explore the use of clear, interpretive nutrition labeling systems (e.g., star ratings, color-coded systems) to potentially influence consumer portion expectations.
- What are the limitations?
- The effect size was small, and not all food categories showed a significant reduction in perceived portion size. The study used mock packages, not actual products.
