Abstract
BACKGROUND
The aim of the study was to conduct a systematic review to comprehensively evaluate the relationship between pistachio intake and obesity.
METHODS
We searched 6 databases and acquired parameters from randomized controlled trials regarding obesity, including body weight, body mass index (BMI), and waist circumference. A fixed-effect model was applied to the meta-analysis for the weighted mean difference (WMD) between a diet with pistachios and a control diet.
RESULTS
Eleven trials including a total of 1593 subjects met the inclusion criteria. Compared to the group on a control diet, the pistachio diet group showed lower BMI values (WMD: -0.18 kg/m; 95% confidence interval [CI]: -0.26, -0.11 kg/m; I = 29.8%) and no differences in body weight (WMD: -0.22 kg; 95% CI: -0.50, 0.07 kg; I = 0.0%) or waist circumference (WMD: 0.76 cm; 95% CI: -0.11, 1.63 cm; I = 7.0%).
CONCLUSION
A diet with pistachios reduced BMI and had no significant effects on body weight and waist circumference.
