Life cycle assessments (LCAs) for food products must incorporate nutrition-related health impacts to provide a comprehensive understanding of their overall sustainability. This sustainability research insight is drawn from a 2024 study published in The International Journal of Life Cycle Assessment. Using Expert workshop and framework development, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When evaluating food products, move beyond purely environmental metrics to include the human health impacts stemming from nutritional quality and dietary patterns.

Key Findings
- 01A framework based on Global Burden of Disease (GBD) risk ratios is a viable starting point for assessing population health risks from diets, provided dietary context and limitations are acknowledged.
- 02Adult-derived dietary risk factors should not be applied to children due to potential misrepresentation.
- 03A wider range of dietary patterns needs to be considered for improved global coverage in assessment frameworks.
- 04Metrics complementary to Disability-Adjusted Life Years (DALYs), such as nutrient adequacy (e.g., vitamin A, iron), should be used to complement health impact assessments.
Application
Design takeaway
When evaluating food products, move beyond purely environmental metrics to include the human health impacts stemming from nutritional quality and dietary patterns.
How to apply
When designing or evaluating food products, use LCA tools that can incorporate nutritional health metrics, and consider consulting with nutrition experts to ensure accurate assessment of health impacts.
Project actions
- 01When researching food products, consider how their nutritional content might impact long-term health, not just their production emissions.
- 02If your design project involves food, think about how to improve both its environmental sustainability and its nutritional value.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Brings together expert opinion to develop a consensus-based framework.
- +Addresses a critical gap in current life cycle assessment methodologies for food.
Limitations
It can be challenging to find comprehensive data for both environmental and nutritional health impacts for all food products. Expert consensus on quantifying these impacts is still evolving.
Reliability & validity
The validity of the framework relies on the consensus of nutrition experts. Reliability in applying the framework would depend on consistent data availability and interpretation across different studies.
Think critically
If a food product has a low environmental impact but is nutritionally poor or contributes to negative health outcomes, can it truly be considered sustainable?
Design Principles
"Holistic sustainability assessment requires integrating environmental, social, and human health considerations throughout a product's life cycle."
Traditional LCAs often focus on environmental metrics, overlooking the significant human health consequences of dietary patterns. By including nutritional health, designers and researchers can develop food systems and products that are not only environmentally sound but also promote public well-being, leading to more holistic and responsible design decisions.
What This Means for Your Design
To truly know if a food is 'good', we need to look at both its environmental footprint and how its nutrition affects people's health.
How to use in your project
- 1.Use this research to justify the inclusion of nutritional health as a key evaluation criterion in your design project, alongside traditional environmental metrics.
- 2.Cite this study when discussing the limitations of standard life cycle assessments and the need for a more comprehensive approach.

Paragraph starter
This research highlights the critical need to integrate nutrition-related human health impacts into the life cycle assessment of food products. By considering metrics such as DALYs and nutrient adequacy, alongside traditional environmental indicators, designers can develop a more holistic understanding of a food's true sustainability, moving beyond purely ecological concerns to encompass public well-being.
