                 Abstract
                 We investigated the effects of a high walnut diet and a high unsalted cashew
                 nut diet on selected markers of the metabolic syndrome. In a randomized,   Information: British Journal of

                 Results: Both the walnut and the unsalted cashew nut intervention diets had
                 no significant effect on the HDL-cholesterol, TAG, total cholesterol, LDL-cho-
                 lesterol, serum fructosamine, serum high-sensitivity C-reactive protein, blood
                 pressure and serum uric acid concentrations when compared to the control
                 diet. Low baseline LDL-cholesterol concentrations in the cashew nut group
                 may have masked a possible nut-related benefit. Plasma glucose concentra-
                 tions increased significantly (P = 0·04) in the cashew nut group compared
                 to the control group. By contrast, serum fructosamine was unchanged in the
                 cashew nut group while the control group had significantly increased
                 (P = 0·04) concentrations of this short-term marker of glycaemic control.
                 Subjects displayed no improvement in the markers of the metabolic syndrome
                 after following a walnut diet or a cashew nut diet compared to a control diet
                 while maintaining body weight.
