Results across scientific findings have yet to find a definitive conclusion to support whether nutrition students and professionals are at higher risk than other population subgroups, due to differing results in the research literature. There are only a few notable scientific works that, in an attempt to explore the breadth and depth of the still vaguely-understood illness, have tried to identify which groups in society are most vulnerable to its onset. This includes a 2008 German study, which based its research on the widespread suspicion that the most nutritionally-informed, such as university nutrition students, are a potential high-risk group for eating disorders, due to a substantial accumulation of knowledge on food and its relationship to health; the idea being that the more one knows about health, the more likely an unhealthy fixation about being healthy can develop. This study also inferred that orthorexic tendencies may even fuel a desire to study the science, indicating that many within this field might suffer from the disorder before commencing the course. However the results found that the students in the study, upon initial embarkation of their degree, did not have higher orthorexic values than other non-nutrition university students, and thus the report concluded that further research is needed to clarify the relationship between food-education and the onset of ON.
