"For years, scientists have believed that inflammation inevitably increases
with age, quietly fuelling diseases like heart disease, dementia and diabetes.
But a new study of Indigenous populations challenges that idea and could
reshape how we think about ageing itself.
For decades, scientists have identified chronic low-level inflammation – called
“inflammaging” – as one of the primary drivers of age-related diseases. Think
of it as your body’s immune system stuck in overdrive – constantly fighting
battles that don’t exist, gradually wearing down organs and systems.
But inflammaging might not be a universal feature of ageing after all. Instead,
it could be a byproduct of how we live in modern society.
The research, published in
Nature Aging, compared patterns of inflammation in
four very different communities around the world. Two groups were from modern,
industrialised societies – older adults living in Italy and Singapore.
The other two were Indigenous communities who live more traditional lifestyles:
the Tsimane people of the Bolivian Amazon and the Orang Asli in the forests of
Malaysia.
The researchers analysed blood samples from more than 2,800 people, looking at
a wide range of inflammatory molecules, known as cytokines. Their goal was to
find out whether a pattern seen in earlier studies – where certain signs of
inflammation rise with age and are linked to disease – also appears in other
parts of the world.
The answer, it turns out, is both yes and no."
