title: Concentrations of conjugated linoleic acids in neonatal blood in relationship to those in maternal blood.
abstract: In this study, the proportions of conjugated linoleic acids (CLA) in total lipids of plasma, lipoproteins and erythrocytes from maternal blood and from venous cord blood of 20 pregnant women consuming conventional western diets after delivery were determined. cis-9, trans-11 CLA was the only isomer detected, and its proportions in maternal blood lipids were relatively low. Mean proportions in plasma, lipoproteins and erythrocytes of mothers were between 0.20 and 0.25 mol/100 mol of total fatty acids. Proportions in cord blood lipids were even lower than those of maternal lipids (values in mol/100 mol: plasma, 0.19+/-0.04; VLDL, 0.20+/-0.06; LDL, 0.15+/-0.03; HDL, 0.14+/-0.06; erythrocytes, 0.12+/-0.05). There was some significant (P<0.05) linear relationship between CLA in maternal lipids and neonatal lipids. The data of this study suggest that CLA proportions in fetal blood lipids are low if mothers are consuming conventional western diets. It is moreover concluded that CLA concentrations in fetal blood lipids are related with maternal CLA intake.
