The human microbiome of isolated populations exhibits significantly higher diversity and a broader range of genetic functions compared to westernized individuals. This human factors research insight is drawn from a 2015 study published in Science Advances. Using Microbiome and resistome analysis, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design interventions that aim to support or restore microbial diversity, rather than inadvertently reducing it, especially in areas related to health, hygiene, and food.

Key Findings
- 01The Yanomami harbored the highest diversity of bacteria and genetic functions ever reported in a human group.
- 02Functional antibiotic resistance genes were present, even without known exposure to commercial antibiotics, suggesting a natural reservoir for these genes.
- 03Westernization significantly impacts human microbiome diversity.
Application
Design takeaway
Design interventions that aim to support or restore microbial diversity, rather than inadvertently reducing it, especially in areas related to health, hygiene, and food.
How to apply
When designing products or services that interact with the human body or its environment (e.g., hygiene products, food packaging, medical devices), consider their potential impact on the diversity and function of the human microbiome.
Project actions
- 01Consider how your design might affect the user's natural microbial environment.
- 02Research the microbiome implications of materials or processes you plan to use.

Variables
Strengths & Limitations
Strengths
- +Study of a truly isolated population provides a unique baseline.
- +Comprehensive analysis of multiple body sites (fecal, oral, skin).
Limitations
It is difficult to find truly 'uncontacted' populations for study, and ethical considerations are paramount. Replicating this exact study outside of such specific contexts is challenging.
Reliability & validity
The study's validity is high due to the unique sample population and advanced analytical methods. Reliability is supported by the consistency of findings across different body sites within the studied group.
Think critically
To what extent can design interventions actively promote or restore beneficial microbial diversity, and what are the ethical considerations involved?
Design Principles
"Preserve and promote baseline human microbial diversity."
Understanding the baseline state of the human microbiome is crucial for developing targeted interventions and appreciating the impact of lifestyle changes on human health. This research highlights the potential loss of beneficial microbial communities due to modern living.
What This Means for Your Design
People who live very isolated lives have way more types of tiny bugs (microbes) in and on them than people in cities. These bugs are important for health, and modern life can reduce them. Even without antibiotics, these isolated people have genes that can fight antibiotics, showing these genes exist naturally.
How to use in your project
- 1.Reference this study when discussing the impact of lifestyle or environmental factors on human health and physiology.
- 2.Use findings to justify the importance of maintaining biological diversity in user-centered design.

Paragraph starter
Research indicates that human populations with limited exposure to Western lifestyles possess a significantly more diverse and functionally rich microbiome. This baseline diversity is crucial for overall health, and modern practices can lead to its reduction. Furthermore, the presence of antibiotic resistance genes in these isolated groups suggests a natural reservoir, highlighting the complex interplay between human biology and environmental factors, which should be considered in design decisions impacting user health.
