Almond consumption improved glycemic control and lipid profiles in patients with type 2 diabetes mellitus.
Almond consumption is associated with ameliorations in obesity , hyperlipidemia , hypertension , and hyperglycemia . The hypothesis of this 12-week r and omized crossover clinical trial was that almond consumption would improve glycemic control and decrease the risk for cardiovascular disease in 20 Chinese patients with type 2 diabetes mellitus ( T2DM ) ( 9 male , 11 female ; 58 years old ; body mass index , 26 kg/m² ) with mild hyperlipidemia . After a 2-week run-in period , patients were assigned to either a control National Cholesterol Education Program step II diet ( control diet ) or an almond diet for 4 weeks , with a 2-week washout period between alternative diets . Almonds were added to the control diet to replace 20 % of total daily calorie intake . Addition of approximately 60 g almonds per day increased dietary intakes of fiber , magnesium , polyunsaturated fatty acid , monounsaturated fatty acid , and vitamin E. Body fat determined with bioelectrical impedance analysis was significantly lower in patients consuming almonds ( almonds vs control : 29.6 % vs 30.4 % ) . The almond diet enhanced plasma α-tocopherol level by a median 26.8 % ( 95 % confidence intervals , 15.1 - 36.6 ) compared with control diet . Furthermore , almond intake decreased total cholesterol , low-density lipoprotein cholesterol , and the ratio of low-density lipoprotein cholesterol to high-density lipoprotein cholesterol by 6.0 % ( 1.6 - 9.4 ) , 11.6 % ( 2.8 - 19.1 ) , and 9.7 % ( 0.3 - 20.9 ) , respectively . Plasma apolipoprotein ( apo ) B levels , apo B/apo A-1 ratio , and nonesterified fatty acid also decreased significantly by 15.6 % ( 5.1 - 25.4 ) , 17.4 % ( 2.8 - 19.9 ) , and 5.5 % ( 3.0 - 14.4 ) , respectively . Compared with subjects in the control diet , those in the almond diet had 4.1 % ( 0.9 - 12.5 ) , 0.8 % ( 0.4 - 6.3 ) , and 9.2 % ( 4.4 - 13.2 ) lower levels of fasting insulin , fasting glucose , and homeostasis model assessment of insulin resistance index , respectively . Our results suggested that incorporation of almonds into a healthy diet has beneficial effects on adiposity , glycemic control , and the lipid profile , thereby potentially decreasing the risk for cardiovascular disease in patients with type 2 diabetes mellitus
