Abstract:
Background and Objectives: Non-alcoholic fatty liver disease (NAFLD) is accused as inducer of both cardiovascular and chronic liver diseases. The aim of the present study was to evaluate the therapeutic effect of combined freeze dried orange juice with its dried pulp supplemented with methionine, as functional food, in comparison to orange bioactive constituents, as parallel formula, in NAFLD rat model. Materials and Methods: Proximate composition, dietary fibers, minerals, total phenolics, fatty acids and phytosterols were determined in the orange functional food. The NAFLD was induced in rats through feeding high fructose diet. The prepared functional food and its parallel formula were evaluated in NAFLD rats through determination of liver fat and plasma lipid profile, malondialdehyde, tumor necrosis factor-α, leptin, insulin and glucose as well as liver and kidney function with histopathological examination of the liver. Insulin resistance (IR) and total cholesterol/high density lipoprotein cholesterol were calculated. Results: Orange functional food was shown to contain 9.17% dietary fibers, 1.4% potassium, 1.4 phenolic content as mg gallic acid/g, oleic acid as the major fatty acid (29.75% of total fatty acids) and 11.97% phytosterols from unsaponifiable matter. The studied formulas produced reduction of liver and plasma lipids, inflammatory and oxidative stress biomarkers, IR and leptin with improving liver function and histopathology pointing to potential management of NAFLD. Conclusion: Orange functional food and its parallel formula were promising in management of NAFLD; with superiority to orange functional food. Phenolic compounds, dietary fibers, phytosterols and mono and poly-unsaturated fatty acids could be responsible to the bioactivity of orange formula.
