In our fitness-conscious world, it’s not uncommon to hear someone talking about “clean eating,” “superfoods,” or the latest diet trend. After all, eating healthily is an essential part of maintaining a good physical and mental state. But what happens when the pursuit of a healthy diet transforms into an obsession? This is the lesser-known realm of Orthorexia Nervosa, a condition where an individual becomes excessively preoccupied with eating ‘pure’ food.

Introduction to Orthorexia Nervosa
Orthorexia Nervosa is a term that may be unfamiliar to many. In a world that seems increasingly obsessed with health and nutrition, orthorexia nervosa remains a lesser-known eating disorder that’s gaining more recognition in recent years.
Brief Description of Orthorexia Nervosa
Orthorexia Nervosa is an eating disorder characterized by an excessive preoccupation with eating healthily. Unlike other well-known eating disorders such as anorexia nervosa or bulimia nervosa, which focus on the quantity of food intake and body image, orthorexia nervosa concerns itself with the quality of food. Those suffering from this condition become fixated on food purity and the health benefits of what they eat, to the extent that it can interfere with their daily lives and overall well-being.
The term “Orthorexia Nervosa” comes from the Greek words “ortho,” meaning correct or right, and “orexia,” meaning appetite. It was first coined by American doctor Steven Bratman in 1997, signifying an “extreme or excessive preoccupation with avoiding foods perceived to be unhealthy.”
Prevalence and Global Impact of Orthorexia Nervosa
Accurate prevalence rates of orthorexia nervosa are challenging to determine due to its relatively recent recognition and the lack of standardized diagnostic criteria. However, studies indicate a rise in cases globally, with prevalence rates varying between different populations. For example, healthcare professionals, athletes, and those following specific diets for ethical or health reasons (like veganism or gluten-free diets) have shown higher tendencies towards this disorder.
Orthorexia nervosa is not currently recognized as a standalone eating disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the main resource used by health professionals for diagnosis. Nonetheless, its impact on individuals and society is undeniable and requires further exploration and understanding [1].
Understanding the Difference Between Healthy Eating and Orthorexia Nervosa
Before delving into the specifics of orthorexia nervosa, it’s important to differentiate it from healthy eating, a concept that we are familiar with and often strive for. Recognizing when the line is crossed from a balanced approach to nutrition to the territory of orthorexia nervosa can be challenging but is crucial for our understanding.
The Concept of Balanced Diet and Healthy Eating
A balanced diet is all about moderation and variety – consuming the right amounts of foods from all food groups. Healthy eating is not just about avoiding junk food or cutting down on certain types of food. It’s about having a well-rounded diet that provides your body with the nutrients it needs for optimal functioning. Healthy eating also acknowledges the occasional indulgence, understanding that food also plays a role in our social and emotional well-being.
When Healthy Eating Crosses the Line: Orthorexia Nervosa
Orthorexia nervosa, on the other hand, arises when the pursuit of a healthy diet becomes extreme, rigid, and all-consuming. It’s when the focus shifts from enjoying balanced, nutritious meals to an obsession with the “purity” of food and a fear of perceived unhealthy foods. This can result in self-imposed restrictions that can exclude essential nutrients, leading to malnutrition and other health problems [2].
Key Characteristics Differentiating Orthorexia Nervosa from Healthy Eating
What separates healthy eaters from individuals with orthorexia nervosa is the impact on their quality of life. Those with orthorexia may experience severe anxiety about eating impure or unhealthy foods, spend excessive amounts of time and money in meal planning and preparation, and avoid social events where they might be confronted with “non-healthy” food choices.
Their self-esteem becomes closely tied to their adherence to their diet rules, and any perceived transgressions can lead to feelings of guilt and shame. In other words, while healthy eaters enjoy their food and maintain a flexible approach to their diet, those with orthorexia lose this flexibility and enjoyment, as their relationship with food becomes more about control and less about nourishment and pleasure [3].
Causes and Risk Factors of Orthorexia Nervosa
Like many mental health disorders, orthorexia nervosa doesn’t have a single identifiable cause. Instead, it’s believed to develop from a complex interplay of various factors such as psychological characteristics, societal and cultural influences, and individual predispositions.
Psychological Factors
Psychological factors can play a significant role in the development of orthorexia nervosa. Certain personality traits, including perfectionism, a need for control, and a propensity towards rigid thinking, may make an individual more susceptible to this disorder. Additionally, a history of anxiety or obsessive-compulsive disorder (OCD) can contribute to its onset [4].
Societal and Cultural Influences
Societal and cultural factors also play a key part in shaping our eating behaviors. In societies where thinness and health are highly prized, the pressure to eat ‘perfectly’ can become overwhelming. These societal expectations can push some individuals towards adopting extreme dietary practices in their pursuit of health and acceptance [5].
Role of Social Media and Celebrity Culture
In the digital age, the influence of social media and celebrity culture cannot be overlooked. The wellness industry is booming online, and the notion of ‘clean eating’ is heavily promoted by numerous influencers, bloggers, and celebrities. While some of the advice may be well-intentioned, the constant exposure to such content can contribute to unrealistic dietary standards and promote orthorexic behaviors.
Predisposition and Other Risk Factors
Certain groups of people seem to be more prone to developing orthorexia nervosa. As mentioned earlier, individuals involved in professions or activities where diet is crucial, such as athletes, healthcare professionals, and performers, show higher tendencies towards this disorder. Similarly, people following diets for health or ethical reasons, such as vegans or those with food allergies, may also be at higher risk. Finally, a personal or family history of eating disorders or other mental health issues may also predispose an individual to orthorexia nervosa [6].
The Psychological and Physical Consequences of Orthorexia Nervosa
While orthorexia nervosa stems from a seemingly benign desire to maintain a healthy diet, it can lead to serious psychological and physical repercussions. This condition often has a multifaceted impact, influencing not just the individual’s health, but also their social and personal lives.
Impact on Mental Health
One of the key implications of orthorexia nervosa is its toll on mental health. The constant anxiety and fear of consuming ‘impure’ or ‘unhealthy’ foods can result in extreme stress, and a failure to adhere to self-imposed dietary rules can lead to feelings of guilt and shame. The rigidity of the eating routine can also fuel obsessive-compulsive tendencies. Moreover, it’s not uncommon for people with orthorexia to also experience other mental health conditions such as depression and anxiety disorders.
Physical Health Consequences
In terms of physical health, orthorexia nervosa can lead to numerous problems resulting from malnutrition and the exclusion of essential nutrients from the diet. Depending on the severity and the specific dietary restrictions, individuals may suffer from weight loss, fatigue, poor bone health, gastrointestinal problems, and a weakened immune system, among other issues. In severe cases, life-threatening complications like heart problems can occur [7].
Social and Relational Consequences
The social and relational impacts of orthorexia nervosa can be as detrimental as the physical and psychological ones. The strict dietary rules can lead individuals to isolate themselves from social situations involving food, straining relationships with family and friends. This isolation, coupled with the time-consuming nature of planning and preparing meals, can result in decreased overall life satisfaction and disruption of personal and professional life.
How Orthorexia Nervosa is Diagnosed
Identifying and diagnosing orthorexia nervosa can be complex due to the lack of established diagnostic criteria in standard mental health manuals such as the DSM-5. However, health professionals have proposed several criteria based on clinical experience and research to guide the diagnostic process.
Diagnostic Criteria for Orthorexia Nervosa
While not officially recognized in the DSM-5, several proposed diagnostic criteria for orthorexia nervosa have been suggested by researchers. These include an obsessive focus on healthy eating, distress or anxiety over violating self-imposed dietary rules, and the impairment of physical health or daily functioning due to strict dietary practices. Furthermore, the individual’s self-worth becomes excessively tied to their adherence to a healthy diet [8].
Role of Health Professionals in Diagnosis
As with other mental health conditions, diagnosing orthorexia nervosa involves a comprehensive evaluation by a mental health or medical professional. This evaluation often involves a detailed discussion about the individual’s eating habits, attitudes towards food, physical health, and the impact of these behaviors on their daily life. Various questionnaires and assessment tools, specifically designed to detect orthorexic tendencies, can also be used to aid the diagnosis.
Common Misdiagnoses and Overlaps with Other Disorders
Due to its focus on the quality of food, orthorexia nervosa can often be misdiagnosed as other eating disorders, such as anorexia nervosa or avoidant/restrictive food intake disorder (ARFID). Additionally, it may coexist with other mental health conditions such as obsessive-compulsive disorder (OCD), anxiety disorders, or depression. It’s therefore crucial that health professionals are aware of this condition and consider it in their evaluations when individuals present with excessive concerns about the healthiness of their diet.
