Short answer
Prioritize educational and behavioral design strategies that foster positive attitudes towards food waste reduction in Generation Z, as this is the most influential factor affecting their behavior and, consequently, food security.
- Field
- Sustainability
- Source
- Food Research (2025)
- Method
- Mixed-methods approach utilizing the Theory of Planned Behavior (TPB).
- Sample
- 150 participants
- Evidence
- Moderate effect
Generation Z's attitudes, subjective norms, and perceived behavioral control collectively explain 26% of their food waste behaviors, which in turn directly affects sustainable food security. This sustainability research insight is drawn from a 2025 study published in Food Research. Using Mixed-methods approach utilizing the theory of planned behavior (tpb). with 150 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize educational and behavioral design strategies that foster positive attitudes towards food waste reduction in Generation Z, as this is the most influential factor affecting their behavior and, consequently, food security.

Key Findings
- 01Generation Z's food waste behaviors contribute 26% to food security.
- 02Attitudes towards food waste have the most significant influence on their behavior.
- 03Subjective norms and behavioral control also play a role in their food wastage actions.
Application
Design takeaway
Prioritize educational and behavioral design strategies that foster positive attitudes towards food waste reduction in Generation Z, as this is the most influential factor affecting their behavior and, consequently, food security.
How to apply
When designing products or services related to food consumption or waste management for a younger demographic, incorporate elements that positively influence their attitudes towards reducing waste, such as highlighting environmental benefits or social responsibility.
Project actions
- 01When researching food waste, consider the psychological factors influencing behavior, not just the practical aspects.
- 02Use frameworks like the Theory of Planned Behavior to structure your investigation into user habits.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a robust theoretical framework (Theory of Planned Behavior).
- +Employs a mixed-methods approach for comprehensive analysis.
Limitations
The sample size of 150 might limit the generalizability of findings. The study focuses on a specific age group, so results may not apply universally.
Reliability & validity
The use of the Theory of Planned Behavior provides a structured approach to measuring psychological constructs, potentially enhancing validity. Reliability would depend on the consistency of measurement tools used for attitudes, norms, and control.
Think critically
How might the 'environmentally-conscious innovator' perception of Generation Z conflict with their actual food waste behaviors, and what design strategies could bridge this gap?
Design Principles
"Behavioral interventions targeting attitudes are highly effective in influencing sustainable consumption practices."
Understanding the drivers behind Generation Z's food waste is critical for developing targeted interventions. This demographic's consumption patterns have a measurable impact on resource availability and the global food system's sustainability.
What This Means for Your Design
What young people think about wasting food and how easy or hard they find it to avoid wasting food really matters – it affects how much food is available for everyone by about a quarter.

Paragraph starter
Research indicates that Generation Z's food waste behaviors, influenced by their attitudes, subjective norms, and perceived behavioral control, account for a significant portion (26%) of their impact on food security. Attitudes, in particular, emerge as the most potent driver. This highlights the importance of designing interventions that specifically target and shape positive attitudes towards sustainable food management within this demographic to effectively mitigate food waste and enhance global food security.
