Non-Alcoholic Fatty Liver Disease and Nutrition: A Literature Review.

Prevalence of non-alcoholic fatty liver in Western countries is likely concurrent with epidemic obesity and also it is associated with metabolic disorders, Patients with non-alcoholic fatty liver usually have insulin resistance. The prevalence of non-alcoholic fatty liver has been increased in individuals who have normal body mass index. However, these people have central obesity and latent insulin resistance. In epidemiologic studies, these patients with normal weight have unhealthy diet.

Olive oil is the most important source of oleic acid (other sources are avocado and seeds). MUFA decreases the blood lipid indices, and it reduces the ratio of low-density lipoprotein (LDL) and total cholesterol to high-density lipoprotein (HDL) as well. In one meta-analysis study, the effect of various diets on lipid and glycemic indices has been evaluated. The result of this meta analysis indicated that diets rich of monounsaturated fatty acids decreases TG concentration and blood cholesterol 19% and 22%, respectively. Also, it increases the rate of HDL but it does not affect LDL
