Method: Qualitative analysis of ingredient lists and inferential analysis of manufacturing processes.
Evidence: Moderate effect

Foods with long ingredient lists, particularly those containing industrial additives and modified food substances, are indicative of complex manufacturing processes that often require significant energy, water, and generate more waste. This resource management research insight is drawn from a 2019 study published in Public Health Nutrition. Using Qualitative analysis of ingredient lists and inferential analysis of manufacturing processes., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Minimize the use of highly processed ingredients and additives to reduce the environmental footprint of food products.

Ingredient complexity in food products increases resource intensity and waste

Public Health Nutrition · 2019

Key Findings

01Ultra-processed foods often contain ingredients rarely used in home kitchens (e.g., high-fructose corn syrup, hydrogenated oils).
02A high number of additives (flavours, colours, emulsifiers, sweeteners, thickeners) is characteristic of ultra-processed foods.
03The manufacturing of these foods involves fractioning, chemical modification, and assembly of substances, implying significant industrial processing.
04These processes are designed for profitability, shelf-life, and hyper-palatability, often at the expense of natural food components.

Application

Design takeaway

Minimize the use of highly processed ingredients and additives to reduce the environmental footprint of food products.

How to apply

When designing food products or packaging, analyze the ingredient list to understand the level of processing and its associated resource demands. Opt for fewer, simpler ingredients where possible.

Project actions

01Compare the ingredient lists of two similar food products (e.g., two brands of cookies) and discuss the potential resource differences.
02Investigate the manufacturing processes for common food additives to understand their environmental impact.

Method & Evidence

AimTo identify the relationship between the complexity of food ingredient lists and the resources required for their production and potential waste generation.

MethodQualitative analysis of ingredient lists and inferential analysis of manufacturing processes.

ProcedureAnalyze ingredient lists of various food products, categorizing them based on the presence of industrial additives, modified food substances, and the sheer number of ingredients. Infer the likely manufacturing processes and resource demands associated with these complex lists.

ContextFood product development and consumer goods.

Variables

IVComplexity of food ingredient list (number of ingredients, presence of industrial additives/modified substances).

DVResource intensity (energy, water) and waste generation (inferred).

CVType of food product (e.g., comparing similar product categories).

Strengths & Limitations

Strengths

+Provides a practical method for identifying potentially resource-intensive food products.
+Highlights the link between food formulation and industrial processing.

Limitations

The study does not quantify the exact amount of resources used or waste produced, relying on inferences from ingredient lists and processing descriptions.

Reliability & validity

The reliability of identifying ultra-processed foods based on ingredient lists is high due to the NOVA classification's clear criteria. Validity is supported by the correlation between these ingredients and known industrial processing techniques, though direct measurement of resource impact would strengthen it.

Think critically

To what extent can the 'convenience' and 'hyper-palatability' of ultra-processed foods justify their higher resource consumption and waste generation from a design perspective?

Design Principles

"Simplicity in ingredients and processing leads to greater resource efficiency and reduced waste."

Understanding the processing involved in food production is crucial for evaluating its environmental impact. Complex ingredient lists signal a departure from natural states, often necessitating energy-intensive refining, chemical modification, and the use of specialized additives, all of which have resource implications.

What This Means for Your Design

If a food has a really long list of ingredients, especially ones you can't pronounce or don't use at home, it probably took a lot of energy and resources to make, and might create more waste.

How to use in your project

1.Use this insight to justify design choices that aim to reduce the complexity of ingredients or processing in a food-related project.
2.Analyze the 'resource intensity' of different design options based on their ingredient lists and inferred manufacturing processes.

Paragraph starter

The complexity of a food product's ingredient list, particularly the inclusion of industrial additives and modified food substances, is a strong indicator of its resource intensity and potential waste generation. Ultra-processed foods, characterized by such ingredient lists, often involve energy-intensive fractioning, chemical modification, and assembly processes. Designers aiming for greater sustainability should consider simplifying ingredient compositions and processing methods to minimize their environmental footprint.
