Persons dependent on opioids often characterized by the coexistence of a whole range of dysfunctional behaviors, which may also lead to eating disorders.

Impulsive and risky behavior, conducive to the formation of polysubstance dependence, including food addiction, which manifests itself in the uncontrollable craving substances, that are quickly metabolized and turned into sugar in the bloodstream.

Aim of the study was to assess the nutritional status and carbohydrates consumption in opioid-dependent individuals treated with methadone substitution therapy.

Fourteen opioid addicts during methadone maintenance treatment were examined. Eighteen healthy individuals matched for age and gender were included to the control group. The 24hour hour diet recalls interview was used. After the dietary recall, a special questionnaire was administered to ascertain frequency of refined carbohydrates consumptions during the past 30days.

It was found the nutritional deficiencies in the diet and poor nutritional status in opioid-addicts compared to healthy ones. Opioid-dependent individuals significantly more often snack between meals. It was found increased consumption monosaccharides and disaccharides in foods and beverages in opioid-addicts compared to healthy ones (P<0.05).

Investigation of dietary behaviors may facilitate understanding of dynamics of addiction, so that we can use more effective methods of treatment.
