Habitual high intake of fatty fish is related to lower levels of F2 -isoprostane in healthy women

Abstract Objective The aim of this study was to determine whether habitual dietary intake of fatty fish, whole grains, fruits and vegetables, or a combination of them all, is associated with oxidative stress levels, measured as urine concentration of 8-iso-prostaglandin F2α (8-iso-PGF2α ) in healthy...

Description
Summary:Abstract Objective The aim of this study was to determine whether habitual dietary intake of fatty fish, whole grains, fruits and vegetables, or a combination of them all, is associated with oxidative stress levels, measured as urine concentration of 8-iso-prostaglandin F2α (8-iso-PGF2α ) in healthy women. Methods Eighty-one participants were included in this cross-sectional study. Mean age of the women was 26.1 ± 6.2 (mean ± SD) years and mean body mass index (BMI) was 22.4 ± 3.0 kg/m2 . The concentration of 8-iso-PGF2α was determined in urine, and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels were determined in blood. Participants' habitual fish, whole grain, fruit, and vegetable intake was estimated from a food frequency questionnaire. Results In the multivariate analysis, there was a significant inverse association between 8-iso-PGF2α and high fatty fish intake ( P
