Diets Containing Pistachios Reduce Systolic Blood Pressure and Peripheral Vascular Responses to Stress in Adults With Dyslipidemia
Nut consumption reduces cardiovascular risk , and reductions in blood pressure and peripheral vascular resistance may be important mediators of this relationship . We evaluated effects of pistachios on flow-mediated dilation and blood pressure response to acute stress . Twenty-eight adults with dyslipidemia completed a r and omized , crossover , controlled-feeding study . All of the meals were provided and calories were controlled . After 2 weeks on a typical Western diet ( 35 % total fat and 11 % saturated fat ) , test diets were presented in counterbalanced order for 4 weeks each , a low-fat control diet ( 25 % total fat and 8 % saturated fat ) , a diet containing 10 % of energy from pistachios ( on average , 1 serving per day ; 30 % total fat and 8 % saturated fat ) , and a diet containing 20 % of energy from pistachios ( on average , 2 servings per day , 34 % total fat and 8 % saturated fat ) . None of the resting hemodynamic measures significantly differed from pretreatment values . When resting and stress levels were included in the repeated- measures analysis , average reductions in systolic blood pressure were greater after the diet containing 1 serving per day versus 2 servings per day of pistachios ( mean change in systolic blood pressure , −4.8 vs −2.4 mm Hg , respectively ; P<0.05 ) . After the higher dose , there were significant reductions in peripheral resistance ( −62.1 dyne·s × cm−5 ) and heart rate ( −3 bpm ) versus the control diet ( P<0.0001 ) . These changes were partially offset by increases in cardiac output . There was no effect of diet on fasting flow-mediated dilation . Reductions in peripheral vascular constriction and the result ing decrease in hemodynamic load may be important contributors to lower risk in nut consumers
