More than 15% of total energy was provided by simple sugars in these patients. The average population attributable risk of DM (PAR_DM) in the total population was 17.84% based on the intake of fructose and glucose, which was close to the proportion of diabetic patients in this survey by considering the proportion of pre-diabetic patients. <b>Conclusions:</b> Regarding the significant effect of dietary patterns on the development of DM, the authors suggest developing educational programs to help individuals maintain a balanced diet to decrease the rate of DM in the coming years.</span></span></span></div> Demography, Dietary pattern, Diabetes mellitus, Non-communicable diseases, Nutritional assessment. 413 422 http://jnfs.ssu.ac.ir/browse.php?a_code=A-10-1232-1&slc_lang=en&sid=1 Masoumeh Moslemi 0000-0002-7120-3329 No Halal Research Center of IRI., Iran Food and Drug Administration, Ministry of Health and Medical Education, Tehran, Iran Marjan Mahdavi-Roshan 0000-0002-2645-6714 No Department of Cardiology, Cardiovascular Diseases Research Center, Heshmat Hospital, School of Medicine, Guilan University of Medical Sciences, Rasht, Iran Farahnaz Joukar 0000-0001-8432-8879 No Gastrointestinal and Liver Diseases Research Center, Guilan University of Medical Sciences, Rasht, Iran.
