As we age, our bodies naturally undergo a wide range of biological changes. However, one silent and persistent process has drawn increasing attention in recent years: inflammaging. This term refers to chronic, low-grade inflammation that accumulates with age, contributing to conditions such as cardiovascular disease, type 2 diabetes, Alzheimer’s, cancer, and frailty. Surprisingly, some indigenous communities—such as the Tsimane of Bolivia and the Orang Asli of Malaysia—appear to age without the same inflammatory burden seen in industrialized societies.
At betterhealthfacts.com, we explore how these traditional lifestyles offer clues to healthier aging. Backed by scientific studies, including groundbreaking research published in Nature Aging, this article unpacks how hunter-gatherer lifestyles may naturally shield the body from chronic inflammation and what modern individuals can do to mimic these protective benefits.
Understanding Inflammaging: What Is It?
Inflammaging is a term that describes the gradual rise of systemic inflammation as we age. Unlike acute inflammation, which is a beneficial immune response to injury or infection, chronic low-level inflammation is harmful and contributes to tissue damage and age-related diseases.
Research has shown that people in modern industrialized societies often exhibit higher levels of inflammatory markers like CRP (C-reactive protein), IL-6 (interleukin-6), and TNF-alpha (tumor necrosis factor-alpha) as they get older—even in the absence of overt infection.
"Inflammaging represents a significant risk factor for both morbidity and mortality in elderly populations. It is driven by lifestyle and environmental factors." — Journal of Gerontology, Medical Sciences
Why Does Inflammaging Happen?
There are several reasons why chronic inflammation tends to rise with age, particularly in modern environments:
- Excess body fat, especially visceral fat, secretes pro-inflammatory cytokines.
- Sedentary behavior reduces anti-inflammatory cytokine release associated with physical activity.
- Ultra-processed diets rich in sugars, trans fats, and additives contribute to gut dysbiosis and inflammation.
- Environmental pollutants, poor sleep, and chronic stress elevate systemic inflammation.
- Immune system aging leads to dysregulation, overproduction of inflammatory mediators, and impaired resolution of inflammation.
What the Nature Aging Study Reveals
A study published in Nature Aging compared inflammation levels in modern urban dwellers with those in indigenous communities like the Tsimane and Orang Asli. These groups retain traditional lifestyles involving physically active daily routines, minimally processed diets, and close-knit community structures. The findings were illuminating:
- The Tsimane, for example, showed extremely low levels of systemic inflammation even into older age.
- Despite frequent exposure to infectious agents, these populations did not show the same chronic inflammation seen in Westerners.
- They exhibited low levels of CRP and IL-6 across age groups, suggesting that chronic inflammation is not inevitable with aging.
“These findings challenge the assumption that inflammation naturally rises with age. Environmental context plays a powerful role in immune system regulation.” — Nature Aging, 2023
Who Are the Tsimane and Orang Asli?
The Tsimane (Bolivia)
The Tsimane are a forager-horticulturalist society in the Bolivian Amazon. Their diet is composed mainly of plantains, rice, manioc, and small game, with very limited processed foods. They walk an average of 15,000 to 17,000 steps per day and engage in physical labor such as fishing, farming, and gathering.
The Orang Asli (Malaysia)
The Orang Asli, indigenous peoples of Peninsular Malaysia, live in rural rainforest environments and rely on subsistence farming, fishing, and foraging. Their diet includes roots, tubers, fruits, fish, and minimal sugar or refined carbs. Community cohesion and stress-buffering cultural traditions are strong.
Comparing Traditional vs Modern Aging
| Aspect | Traditional Lifestyle | Modern Lifestyle |
|---|---|---|
| Physical Activity | High (hunting, gathering, farming) | Low (sedentary jobs, screen time) |
| Diet Quality | Whole foods, fiber-rich, low sugar | Processed foods, high sugar/fats |
| Inflammatory Biomarkers | Low (CRP, IL-6) | Elevated with age |
| Stress Levels | Intermittent, often community-buffered | Chronic, isolated, sleep-deprived |
| Gut Microbiota | Diverse, fiber-fed, anti-inflammatory | Dysbiotic, processed-food-fed |
How Diet Impacts Inflammaging
Diet is arguably one of the most potent modulators of chronic inflammation. The traditional diets of the Tsimane and Orang Asli are rich in:
- Unrefined carbohydrates such as yams, tubers, and whole grains
- Omega-3 fatty acids from fish and seeds
- Prebiotic fiber that nourishes beneficial gut microbes
- Natural antioxidants from plants, roots, and berries
In contrast, typical Western diets are high in:
- Refined sugars and starches, leading to insulin resistance
- Trans fats and omega-6-heavy oils, promoting inflammation
- Artificial additives and preservatives
“Nutritional factors regulate inflammatory pathways at a cellular level. Diet is central to inflammaging.” — American Journal of Clinical Nutrition
The Role of Physical Activity
Regular, moderate-intensity physical activity has been shown to reduce systemic inflammation by:
- Lowering levels of pro-inflammatory cytokines like IL-6 and TNF-alpha
- Enhancing insulin sensitivity and metabolic health
- Reducing body fat, particularly visceral adiposity
The key difference is that in indigenous communities, physical activity is integrated naturally into daily life—not performed in isolated gym sessions. They don’t “exercise”; they move continuously through purposeful labor and walking.
Social and Psychological Factors
Hunter-gatherer societies also benefit from:
- Tight community structures that reduce loneliness and anxiety
- Clear cultural roles and multigenerational support systems
- Reduced exposure to artificial light, improving sleep quality
Chronic stress and poor sleep in modern life activate the HPA (hypothalamic-pituitary-adrenal) axis and raise cortisol, fueling inflammatory pathways.
Can We Mimic the Anti-Inflammatory Benefits of Ancestral Lifestyles?
While we may not live in the rainforest or forage for food, modern individuals can adopt habits that emulate these protective patterns. Here’s how:
1. Eat an Anti-Inflammatory Diet
- Prioritize whole, minimally processed foods
- Increase intake of green leafy vegetables, berries, nuts, and fatty fish
- Reduce sugar, trans fats, and processed meats
- Consider a Mediterranean or DASH-style diet
2. Move Frequently
- Walk at least 8,000 to 10,000 steps a day
- Engage in natural movement: gardening, chores, hiking
- Incorporate bodyweight strength training and mobility
3. Manage Stress
- Practice mindfulness or meditation
- Maintain social connections
- Set healthy boundaries with work and digital devices
4. Improve Sleep Hygiene
- Sleep 7–9 hours nightly
- Avoid screens 1 hour before bed
- Establish a regular bedtime routine
5. Nurture Your Microbiome
- Eat fermented foods: yogurt, kefir, kimchi, sauerkraut
- Consume prebiotic fibers from onions, garlic, leeks, and oats
- Avoid excessive antibiotic use unless medically necessary
What Experts Say
“The lifestyle of modern humans has diverged substantially from the one our physiology evolved for. Chronic inflammation is a mismatch disease.” — Dr. Daniel Lieberman, Evolutionary Biologist, Harvard University
“Public health policy should include lifestyle-based anti-inflammatory strategies that mimic ancestral activity, diet, and sleep patterns.” — British Medical Journal, Inflammation Review Panel
Conclusion: Aging Without Inflammaging
Inflammaging is not an inevitable consequence of getting older. The lifestyles of indigenous communities like the Tsimane and Orang Asli offer compelling evidence that environmental factors—especially diet, movement, stress, and sleep—play a dominant role in modulating inflammation over the lifespan.
While we cannot return entirely to ancestral ways of living, we can incorporate key aspects of these protective lifeways into modern routines. The solution lies not in expensive supplements or biohacks, but in honoring the rhythms our bodies evolved to follow.
At betterhealthfacts.com, we believe that a better future lies in learning from our past. By rewilding aspects of our daily routines, we may not only extend life but improve the quality of our years—vibrant, clear-minded, and inflammation-free.
