A diet rich in walnuts favourably influences plasma fatty acid profile in moderately hyperlipidaemic subjects
Objective : To compare two low fat diets one rich in walnuts on parameters of lipid metabolism in a group of hyperlipidaemic subjects . Design : A r and omised cross over study . Setting : Department of Human Nutrition , University of Otago , Dunedin , New Zeal and Subjects : Twenty one men with mean ( s.d ) levels of total and LDL cholesterol of 6.58 ( 0.60 ) and 4.63 ( 0.58 ) respectively . Interventions : For two periods of four weeks subjects were asked to consume two low fat diets ( fat 30 % total energy ) , one containing , on average , 78 g/d walnuts . Walnuts obtained through Lincoln University and the Walnut Growers Group ( South Canterbury ) . Results : Participants reported a higher total fat intake on the walnut diet ( 38 % compared with 30 % on the low fat diet P<0.01 ) The most consistent change in fatty acid profile of triacylglycerol , phospholipid and cholesterol ester on the walnut diet was a significant ( P<0.01 ) increase in linoleic acid . Triacylglycerol linolenate also increased significantly ( P<0.01 ) . Total and LDL cholesterol were lower on both experimental diets than at baseline , 0.25 mmol/l and 0.36 mmol/l respectively on the walnut diet and 0.13 mmol/l and 0.20 mmol/l respectively on the low fat diet . High density lipoprotein cholesterol was higher on both the walnut and low fat diets when compared to baseline ( 0.15 mmol/l and 0.12 mmol/l , respectively ) . When comparing the walnut and low fat diets only apo B was significantly lower ( P<0.05 ) on the walnut diet . Conclusions : Despite an unintended increase in the total fat intake on the walnut diet , fatty acid profile of the major lipid fractions showed changes which might be expected to reduce risk of cardiovascular disease . The reduction of apolipoprotein B suggests a reduction in lipoprotein mediated risk , the relatively low myristic acid content of both diets perhaps explaining the absence of more extensive differences in lipoprotein levels on the two diets .
