Abstract

Few studies have focused on the effects of a soy containing diet on inflammation and serum leptin level among patients with nonalcoholic fatty liver disease (NAFLD). Therefore, we aimed to determine the effects of such a diet in patients with NAFLD. Forty-five patients with NAFLD participated in this parallel randomized clinical trial for 8 weeks. Patients were randomly allocated to these 3 groups: 1) a low-calorie diet, 2) low-calorie low-carbohydrate diet, and 3) low-calorie low-carbohydrate soy containing diet. Low-calorie low-carbohydrate soy containing diet reduced fasting blood sugar (FBS) and serum insulin level significantly compared to other 2 groups (-11.6±2.8 vs. -6.3±1.7 and -3.1±1.0 mg/dl for FBS; and -5.1±1.2 vs. -1.2±0.3 and -1.7±0.5 mg/dl for serum insulin level). Serum hs-CRP level was also reduced significantly following low-calorie low-carbohydrate soy containing diet (-0.8±0.1 vs. -0.1±0.06 and -0.1±0.06 mg/dl). Both systolic and diastolic blood pressures were reduced significantly. Changes in leptin level tended to be different among 3 groups. After trial, 5 patients in each intervention group did not have NAFLD. From 6 patients in grade 2 at the beginning only 1 patient remained and others moved to grade 1. Low-calorie low-carbohydrate soy containing diet could reduce glycemic indices, hs CRP, systolic and diastolic blood pressure in a significant level in patients with NAFLD. However, these effects were dependent on baseline weight and further studies are needed to clarify the effect of such interventions in subjects with different BMI categories. © 2017 Georg Thieme Verlag KG Stuttgart New York.
