- Abstract: Objective:To our knowledge, there is currently no consensus in the literature on the association between die-tary fatty acids and circulating levels in plasma. The aim of this study was to assess the association of theintake of fatty acids with their relative plasma concentrations.Methods:We conducted a study with 300 adults from the population-based health survey in S~ao Paulo city(ISA-Capital 2008). We assessed demographic, lifestyle and anthropometric data, biochemical measure-ments, and two 24-h dietary recalls collected on non-consecutive days. Intake distribution was adjusted forintrapersonal variance to give usual dietary intake using the multiple source method (MSM). Percentage offatty acids in plasma were analyzed by gas chromatography. Thekstatistic, Spearman’s correlation, and mul-tiple linear regression (adjusted for confounders) and ratio limits of agreement were employed to determinethe relationship between plasma and dietary measurements.Results:Low correlation and agreement were found between dietary and plasma fatty acids. Docosahexae-noic acid (b= 0.25;P<0.001) and saturated (b= 0.19;P= 0.048) fatty acids exhibited an association formeans of intake adjusted by the MSM and for confounding variables. A large mean difference, with a largevariation of“ratio limits,”were observed between the measurements.Conclusion:Plasma and dietary polyunsaturated and saturated fatty acids exhibited low correlation andagreement, as well as weak association between each other. No association between intake and plasma con-centrations of monounsaturated fat was found. Plasma fatty acids are not good biomarkers of food intake
