Objectives:
Is there a causal relationship between ginger intake and improvements of major oxidative stress (OS) parameters, such as glutathione peroxidase activity, total antioxidant capacity, alondialdehyde (MDA) levels and CAT activity?
Study design:
This review article included 12 RCTs.
Results and conclusions:
The investigators found ginger intake significantly increased glutathione peroxidase (GPx) activity [SMD = 1.64, 95% CI = 0.43 to 2.85, I2 = 86.8%] compared to control group (group without ginger intake).
The investigators found ginger intake significantly increased total antioxidant capacity (TAC) [SMD = 0.40, 95% CI = 0.06 to 0.73, I2 = 42.8%] compared to control group.
The investigators found ginger intake significantly decreased alondialdehyde (MDA) levels [SMD = -0.69, 95% CI = -1.26 to -0.12, I2 = 85.8%] compared to control group.
The investigators found ginger supplementation non-significantly increased CAT activity [SMD = 1.09, 95% CI = -0.07 to 2.25, I2 = 87.6%].
The investigators concluded this meta-analysis (review article) presents convincing evidence supporting the efficacy of ginger supplementation on improving oxidative stress (OS) levels.
