Key result
Red blood cell saturated fatty acids were positively associated with CRP (β=0.55, p<0.05), while monounsaturated fats (β=-0.88, p<0.01) and polyunsaturated fats were inversely associated with CRP.
Why the study?
Evidence suggests diet modulates systemic inflammation, but the relationship between fatty acid measures, diet quality scores, and plasma inflammatory markers required examination.
Do fatty acid intake and diet quality predict systemic inflammation in Australian adults?

Saturated fat linked to higher inflammation in this small cohort; hypothesis-generating for Mediterranean diet effects, requiring prospective trials before practice change.
Observational (n=92)
Do fatty acid intake and diet quality predict systemic inflammation in Australian adults?
Effect estimate: β = 0.55
p-value: p=< 0.05
Saturated fat intake is positively associated with systemic inflammation, whereas MUFAs, PUFAs, and a Mediterranean diet are inversely associated with inflammation.
Clarke et al. (2023) reported an observational. Fatty acid intake and diet quality was evaluated on Plasma concentrations of inflammatory markers (IL-6, TNF-α, and CRP) (β = 0.55, p=< 0.05). Red blood cell saturated fatty acids were positively associated with CRP (β=0.55, p<0.05), while monounsaturated fats (β=-0.88, p<0.01) and polyunsaturated fats were inversely associated with CRP.
