International Journal of Preventive Medicine (Int J Prev Med)2008-7802002016081017231723EN20160810<strong>Background:</strong> Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver<br />disease in the world. Although some studies have been conducted about dietary intakes of these<br />patients, but the results are inconsistent. The aim of this study was to survey all macronutrients<br />and micronutrients included in dietary intake of these patients for better understanding the factors<br />influencing this disease.<br /><strong>Methods:</strong> The present study is a case‑control conducted in Isfahan city, Iran. The cases were<br />recently diagnosed patients with NAFLD who identified by ultrasonography. The case (159) and<br />control (158) individuals were matched in age and gender. Data of general characteristics and<br />physical activity of individuals were collected through questionnaire. Dietary intake was also<br />collected using 24 h dietary recall questionnaire.<br /><strong>Results:</strong> Waistline and body mass index for the case group were more than the control<br />group (P &lt; 0.05). Physical activity level in healthy individuals was more than patients with NAFLD.<br />Dietary intake of saturated fatty acids and sugar in patients with NAFLD was more than healthy<br />individuals (P &lt; 0.05). Intake of total dietary fiber, folic acid, Vitamin D, zinc, and potassium in<br />healthy individuals was more than patients with NAFLD (P &lt; 0.05).<br /><strong>Conclusions:</strong> In total, it seems the type of dietary intake source is associated with NAFLD.<br />Increasing saturated fatty acids and sugar and decreasing fiber, folic acid, Vitamin D, zinc, and<br />potassium intake might play a role in the progression of this disease.<br /><strong>Keywords:</strong> Dietary intake, nonalcoholic fatty liver disease, physical activityhttp://ijpm.mui.ac.ir/index.php/ijpm/article/view/1723http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1723/2015
