Positive effects of egg-derived phospholipids in patients with metabolic syndrome

Abstract

PurposePatients with metabolic syndrome (MBS) have an increased risk of all-cause mortality, especially from cardiovascular disease. Egg phospholipids (PL) have been shown to exert a positive impact on cholesterol metabolism and inflammation; eggs are an important source of PL. Our study examined potential effects of egg-yolk-derived PL in non-diabetic patients with MBS. MethodsThe study group consisted of 40 patients with MBS diagnosed according to IDF criteria and divided into an experimental group receiving the PL preparation (n−6: n−3 fatty acids ratio: 1.79) and the comparison group receiving an olive oil preparation, for one month (2012/2013year). The studied dosage was 45ml (15ml 3 times per day). It was a randomized, double blinded study. ResultsThe waist to hip ratio, GGTP levels, plasma platelet concentrations and flow mediated vasodilation of brachial artery (FMD) significantly improved in the experimental group. A significant decrease in daytime ABPM blood pressure was noticed in both groups. ConclusionsA phospholipid-enriched diet caused a significant improvement of endothelial vasodilatory function and a significant decrease in waist to hip ratio. A significant decrease in daytime systolic blood pressure were observed in both the phospholipid-enriched and oil-olive group.
