The Claim

In Australian adults, each additional 100 grams of ultra-processed food consumed daily is associated with a 4.0% increase in high-sensitivity C-reactive protein concentration, a biomarker of systemic inflammation, after adjustment for age, sex, education, smoking, physical activity, alcohol intake, and body mass index.

In plain English

In Australian adults, eating 100 more grams of ultra-processed food per day is linked to a 4.0% higher level of high-sensitivity C-reactive protein, a marker of systemic inflammation, after accounting for age, sex, education, smoking, physical activity, alcohol intake, and body mass index.

See the scientific wording

In Australian adults, each additional 100 grams of ultra-processed food consumed daily is associated with a 4.0% increase in high-sensitivity C-reactive protein concentration, a biomarker of systemic inflammation, even after adjusting for age, sex, education, smoking, physical activity, alcohol intake, and body mass index, suggesting a consistent link between dietary processing level and inflammatory status.

Why this might work

Eating more ultra-processed foods introduces artificial additives and broken-down food particles into the gut, which changes the balance of gut bacteria and weakens the gut lining. This allows bacterial toxins to leak into the bloodstream, which triggers the liver to produce more inflammation markers.

    People who eat more packaged snacks, sugary drinks, and ready-made meals tend to have higher levels of a blood marker called hsCRP, which shows their body is experiencing low-grade inflammation — and this is true even if they’re not overweight or have other healthy habits.
