However , subgroup and meta-regression analysis suggested that in subjects with a more profound increase of dietary LA intake , LA might increase the blood CRP level .
Other acute phase reactants including fibrinogen and plasminogen activator inhibitor-1 and adhesion molecules were not significantly changed when LA was increased in diet .
Our meta- analysis suggested that increasing dietary LA intake does not have a significant effect on the blood concentrations of inflammatory markers .
However , the extent of change in dietary LA intake might affect the effect of LA supplementation on CRP
PURPOSE The aim of the present study was to investigate the effect of increasing dietary linoleic acid ( LA ) intake on the blood concentrations of inflammatory markers including cytokines , acute phase reactants and adhesion molecules in adults .
Lecithin has no effect on serum lipoprotein, plasma fibrinogen and macro molecular protein complex levels in hyperlipidaemic men in a double-blind controlled study
Objective : To examine the effects of lecithin on serum lipoprotein , plasma fibrinogen and macro molecular protein complex ( MPC ) levels . Subjects and study design : Twenty free living hyperlipidaemic men participated in this double-blind study which controlled for possible indirect effects . The subjects were r and omly assigned to one of three treatments : frozen yoghurt or frozen yoghurt with 20 g soya bean lecithin or frozen yoghurt with 17 g sunflower oil . Sunflower oil was used to control for the increased energy and linoleic acid intake from lecithin . Yoghurt served as the ‘ vehicle ’ for the lecithin and sunflower oil and yoghurt alone was given to one group to control for possible effects due to the yoghurt ‘ vehicle ’ , as well as other environmental influences . Variables were measured with st and ard methods twice at baseline and after 2 and 4 weeks of treatment . Results : Plasma linoleic acid levels increased significantly with lecithin and sunflower oil treatments indicating that compliance to the treatments were obtained . Lecithin treatment did not have significant effects on serum total cholesterol , triglyceride , high density lipoprotein cholesterol , low density lipoprotein cholesterol , apolipoprotein A , apolipoprotein B or lipoprotein ( a ) levels . Plasma fibrinogen and MPC levels were also not affected by lecithin therapy . Sunflower oil treatment result ed in significant increased body weight , serum TC and decreased MPC levels . Conclusion : Lecithin treatment had no independent effects on serum lipoprotein , plasma fibrinogen or MPC levels in hyperlipidaemic men .
