| Nonalcoholic fatty liver disease (NAFLD) is commonly associated with obesity. This randomized, doubleblind,
placebo-controlled trial aimed to evaluate the effects of turmeric on serum adiponectin and sirtuin 1 (SIRT1) levels,
blood pressure, and body mass index (BMI) in patients with NAFLD. A total of 46 eligible patients with NAFLD (BMI,
25.0∼39.9 kg/m2) were randomly allocated to turmeric and placebo groups using block randomization. The turmeric
group (n=23) was administered 3,000 mg/d turmeric powder in six 500-mg capsules for 12 weeks, whereas the placebo
group (n=23) was administered six placebo capsules/d for 12 weeks. Body weight, BMI, serum SIRT1 and adiponectin
levels, and systolic and diastolic blood pressures were measured at baseline and 12 weeks after intervention. Serum SIRT1
levels increased significantly in the turmeric group compared with the placebo group. Additionally, participants in the turmeric
group exhibited lower weight, BMI, and systolic blood pressure after 12 weeks of intervention compared with the
baseline. Turmeric effectively improved SIRT1 levels in patients with NAFLD compared with the placebo. The efficacy of
turmeric might increase with long-term use at higher doses. |
