Summary
This dietary intervention study by Sofi and colleagues examined the effects of consuming pecorino cheese with naturally elevated levels of cis-9, trans-11 CLA on cardiovascular-related biomarkers in human participants. The paper contributes evidence on whether naturally occurring, food-matrix-delivered CLA — as distinct from synthetic supplements — can influence lipid profiles, inflammation, and blood rheology. The findings are relevant to understanding how pasture-based dairy products, which tend to be higher in CLA, may confer health benefits beyond those of conventional dairy.
UK applicability
Although conducted in Italy using pecorino cheese, the findings are broadly applicable to UK discussions around the nutritional value of pasture-fed dairy, where grass-based systems similarly elevate CLA content in milk and cheese. The study supports UK policy and consumer interest in the health attributes of high-welfare, pasture-based dairy production.
Key measures
Serum lipid concentrations (total cholesterol, LDL, HDL, triglycerides); inflammatory markers (e.g. C-reactive protein, cytokines); haemorheological variables (e.g. blood viscosity, erythrocyte deformability); CLA intake (g/day)
Outcomes reported
The study measured changes in lipid profiles, inflammatory markers, and haemorheological variables in participants consuming pecorino cheese naturally rich in cis-9, trans-11 conjugated linoleic acid (CLA). It assessed whether dietary intake of this dairy product could beneficially modulate cardiovascular risk factors.
