Objective Serum high-sensitivity CRP is a marker of inflammation and an independent
predictor of chronic diseases. However, the effect of diet on serum hs-CRP is unclear. The

and serum hs-CRP. Design and methods We recruited 9778 adults, aged 35–65 years as

Objective
Serum high-sensitivity CRP is a marker of inflammation and an independent predictor of chronic diseases. However, the effect of diet on serum hs-CRP is unclear. The aim of this study was to investigate the relationship between dietary macronutrient intake and serum hs-CRP.
Design and methods
We recruited 9778 adults, aged 35–65 years as part of the MASHAD study. Dietary intake was determined using 24-hour dietary recall and several biochemical parameters including serum hs-CRP were measured. Analysis of covariance was used for assessment of crude and energy-adjusted nutrients across quartiles of serum hs-CRP. To find the association of dietary nutrients intake and serum hs-CRP level, we used logistic regression in different model.
Results
Unadjusted and adjusted multivariate analyses indicate that there was a significant positive association between dietary protein and sodium intake and serum hs-CRP concentrations. There was also a positive association with dietary fat and cholesterol and serum hs-CRP in the adjusted models. There was a significant inverse association between dietary carbohydrate and fiber consumption and serum hs-CRP in both crude and adjusted models.
Conclusion
We have found a significant positive association between the dietary intake of fat, protein, cholesterol and sodium and hs-CRP level, and an inverse correlation between dietary carbohydrate and fiber and serum hs-CRP in a large representative Iranian population.
