Does pistachio supplementation reduce obesity risk?
Study design:
This review article included 11 randomized controlled trials (RCTs) with 1,593 subjects.
The assigned pistachio intake was below 50 g/d in 3 studies.
Intervention times were shorter than 12 weeks in 4 studies.
There was no significant publication bias.
Results and conclusions:
The investigators found compared to the control diet group, the pistachio supplementation regimen significantly decreased BMI [-0.18 kg/m2, 95% CI = -0.26 to -0.11 kg/m2, p 0.001, I2 = 29.8%, p = 0.180].
The investigators found compared to the control diet group, the pistachio supplementation regimen did not significantly change waist circumference [net change = 0.76 cm, 95% CI = -0.11 to 1.63 cm, p = 0.087, I2 = 7.0%, p = 0.340].
The investigators found compared to the control diet group, the pistachio supplementation regimen had no effect on body weight [net change = 0.22 kg, 95% CI = -0.50 to 0.07 kg, p = 0.141, I2 = 0.0%, p = 0.962].
The investigators concluded compared to a controlled dietary intake, an adequate amount of pistachio supplementation lowers BMI without increasing body weight, which supports the view that pistachio consumption is beneficial for human health.
