Brief summary
In this research, the investigators tested the effect of 12-week supplementation with soy isoflavones on non alcoholic fatty liver disease (NAFLD) management and the level of fibroblast growth factor-21 (FGF-21) and fetuin A as markers of NAFLD progression.
Detailed description
Non-alcoholic fatty liver disease (NAFLD) accounts as a crucial health concern with a huge burden on health and economic systems. The aim of the present study was to investigate the effect of soy isoflavone intake on hepatic outcomes and the level of fibroblast growth factor-21 (FGF-21) and fetuin A in patients with NAFLD. Fifty patients with NAFLD were randomized to either receive two tablets of soy isoflavone (100 mg/d) or placebo. Dietary intakes, anthropometric parameters, the serum levels of liver function tests including alanine amino transferase (ALT), aspartate amino transferase (AST) and gamma glutamyl transferase (GGT), FGF-21, fetuin A and hepatic histological features by Fibroscan assessed at study initiation and after week 12.
Interventions
the subjects in the soy isoflavone group were told to take 2 drugs per day, one in the morning after the breakfast and one at night after the dinner and continue this pattern for 12 weeks.
the subjects in the placebo group were told to take 2 placebo tablets per day, one in the morning after the breakfast and one at night after the dinner and continue this pattern for 12 weeks.
