Whereas ON can mainly be described as an excessive concern regarding healthy food, the study\u2019s principal aim was to investigate if ON could be considered a condition related and differentiated from worry, other than OCD, EDs, perfectionism, anxiety, and depression.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Method<\/jats:title>\n                <jats:p>To achieve these aims, 302 individuals from the general population were enrolled and were divided into two groups named \u201cHigh EHQ\u201d and \u201cLow EHQ\u201d, based on their Eating Habits Questionnaire\u2019s score (EHQ-21).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Correlations of ON with EDs and non-adaptive perfectionism constructs emerged independently from Obsessive-Compulsive (OC) symptoms, and the same pattern was observed when comparing the High and the Low EHQ groups.
