Shifting towards a vegan dietary pattern significantly reduces environmental impact compared to even a predominantly plant-based Mediterranean diet. This sustainability research insight is drawn from a 2023 study published in International Journal of Environmental Research and Public Health. Using Life cycle assessment (lca), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize the reduction or elimination of animal-derived components in food systems and related product designs to achieve significant environmental benefits.

01

Key Findings

  • 01The vegan diet demonstrated approximately 44% less total environmental impact compared to the Mediterranean diet.
  • 02Even a low content of animal products (10.6% of calories) in the Mediterranean diet contributed significantly to its environmental footprint.
02

Application

Design takeaway

Prioritize the reduction or elimination of animal-derived components in food systems and related product designs to achieve significant environmental benefits.

How to apply

When designing food products, packaging, or related services, evaluate the environmental impact of ingredient sourcing, production, and waste, favoring plant-based options where possible.

Project actions

  • 01When researching food-related design projects, consider using LCA to quantify environmental impacts.
  • 02Explore how design can facilitate shifts towards more sustainable dietary choices.
03

Method & Evidence

AimTo compare the total environmental impact of a vegan diet versus a Mediterranean diet using Life Cycle Assessment (LCA).
MethodLife Cycle Assessment (LCA)
ProcedureThe study calculated the environmental impact of two theoretical one-week diets (2000 kcal/day) adhering to Italian nutritional recommendations: one vegan and one Mediterranean with a low percentage of animal products. LCA was used to quantify the total environmental impact.
ContextDietary patterns and their environmental impact.

Variables

IVDietary pattern (Vegan vs. Mediterranean)
DVTotal environmental impact (measured by LCA)
CVCaloric intake (2000 kcal/day), macronutrient rates, adherence to Italian nutritional recommendations.
04

Strengths & Limitations

Strengths

  • +Utilizes a robust methodology (LCA) for environmental impact assessment.
  • +Compares two relevant and widely discussed dietary patterns.

Limitations

The specific LCA methodology and regional data used might influence the exact percentage difference in environmental impact.

Reliability & validity

The reliability of the LCA depends on the quality and comprehensiveness of the data used. Validity is supported by the use of a standardized LCA methodology and comparison against established nutritional guidelines.

Think critically

To what extent do regional variations in food production and consumption habits affect the observed environmental impact differences between these diets?

05

Design Principles

"Minimize the ecological footprint of consumption by favoring plant-based alternatives over animal products."

Understanding the environmental consequences of food choices is crucial for designing sustainable systems and products. This insight highlights that even small inclusions of animal products can have a disproportionately large environmental cost, informing strategies for reducing ecological pressure.

06

What This Means for Your Design

Eating vegan food is much better for the planet than eating a Mediterranean diet, even if the Mediterranean diet has only a little bit of meat or dairy.

How to use in your project

  • 1.Use this study to justify the selection of a plant-based approach in your design project's material or system choices.
  • 2.Cite this research when discussing the environmental benefits of reducing animal product consumption.
