Orthorexia nervosa is a relatively new term in the field of eating disorders that refers to an obsession with healthy eating that becomes so severe that it interferes with a person’s life and well-being. Dr. Steven Bratman coined the term “orthorexia” in 1998 after observing that some of his patients had developed an unhealthy obsession with eating healthy foods. Although not officially recognized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), orthorexia nervosa is gaining popularity among healthcare professionals and researchers due to its rising prevalence and the significant impact it can have on people’s mental and physical health.
Define Orthorexia Nervosa
Orthorexia nervosa is distinguished by an obsessive focus on eating foods that the individual perceives to be healthy while avoiding foods that the individual considers to be unhealthy or impure. Orthorexia, unlike other eating disorders, is primarily concerned with food quality and purity, rather than body weight or shape. The condition can result in severe dietary restrictions, social isolation, and an obsession with food that takes over an individual’s life.
While maintaining a healthy diet is generally regarded as beneficial, people with orthorexia take it to the next level, making food quality the primary focus of their lives. Regardless of the individual’s desire to achieve optimal health through diet, this obsession can lead to nutritional deficiencies, weight loss, and a decline in overall health.
Criteria and Symptoms of Orthorexia Nervosa
Orthorexia nervosa is not yet officially recognized as a distinct eating disorder in the DSM-5, but it shares characteristics with anorexia nervosa and obsessive-compulsive disorder (OCD). Dr. Bratman proposed a set of criteria for identifying orthorexia, which include:
- An Obsessive Focus on Healthy Eating: People with orthorexia devote an inordinate amount of time to thinking about, planning, and preparing meals that follow their strict dietary guidelines. This focus frequently interferes with other areas of life, such as work, social activities, and relationships.
- Escalating Dietary Restrictions: Over time, people with orthorexia may remove entire food groups from their diet, such as dairy, grains, or fats, because they believe these foods are unhealthy. These restrictions can cause severe malnutrition and weight loss.
- Emotional Distress Due to Food Choices: Breaking their self-imposed dietary rules can cause significant anxiety, guilt, or shame. This emotional distress reinforces the person’s restrictive eating habits.
- Impact on Physical and Mental Health: Despite the desire to improve health, the restrictive eating patterns associated with orthorexia can lead to a variety of physical and mental health problems, including nutritional deficiencies, decreased energy levels, social isolation, and an increased risk of developing other mental health disorders.
Prevalence of Orthorexia Nervosa
The prevalence of orthorexia nervosa is difficult to estimate, partly because it is not yet an official diagnosis and can be difficult to distinguish from other eating disorders or obsessive-compulsive behaviors. However, research indicates that orthorexia may be more common than previously thought, particularly among certain populations.
General Population
A 2022 study published in the International Journal of Eating Disorders estimated that the prevalence of orthorexia nervosa in the general population ranges between 1% and 7%, depending on the diagnostic criteria used. The study also discovered that orthorexia is more common in people with a strong interest in health and wellness, such as fitness enthusiasts, athletes, and healthcare providers.
At Risk Populations
Certain populations are more likely to develop orthorexia nervosa. For example, a 2023 survey conducted by the Journal of Nutrition Education and Behavior discovered that up to 21% of college students exhibit orthorexia-like behaviors, particularly those studying nutrition, dietetics, or other health-related fields. This implies that people who are extremely knowledgeable about nutrition and health may be more prone to developing an unhealthy obsession with food purity.
Furthermore, healthcare professionals, particularly those working in diet and nutrition, may be at a higher risk. A 2023 study published in the Journal of Occupational Health discovered that up to 35% of dietitians and nutritionists show symptoms of orthorexia nervosa. This could be due to the pressure to maintain a healthy diet as part of their professional identity, which leads to an overemphasis on food selection.
Gendered and Age Differences
Research on gender differences in orthorexia prevalence has yielded mixed results. Some studies indicate that orthorexia is more common in women, while others show similar rates in men and women. However, the condition appears to be more common in young adults, particularly those aged 18 to 35, who are more likely to be exposed to social media and other influences that encourage extreme health behaviors.
Risk Factors of Orthorexia Nervosa
Several factors can increase the likelihood of developing orthorexia nervosa. These risk factors can be divided into three categories: psychological, social, and environmental.
Psychological factors
- Perfectionism: People with perfectionist tendencies may be more likely to develop orthorexia nervosa. The desire to achieve an ideal diet or lifestyle can result in rigid and obsessive food-related behaviors.
- Anxiety and OCD: Orthorexia nervosa is strongly associated with anxiety disorders, particularly obsessive-compulsive disorder (OCD). Individuals with OCD may develop orthorexia to exert control over their surroundings and reduce anxiety.
- Past Eating Disorders: People who have struggled with other eating disorders, such as anorexia nervosa or bulimia nervosa, may be more likely to develop orthorexia. The shift from a focus on body weight to a focus on food purity can be subtle and go unnoticed until the behavior becomes severe.
Social Factors.
- Cultural Influences: Many cultures place a strong emphasis on healthy eating and physical fitness. The rise of social media has amplified these cultural messages, which frequently depict an idealized version of health that is difficult to attain. Individuals may develop orthorexia as a result of their efforts to meet these unrealistic standards.
- Peer Pressure: Social circles that prioritize health and wellness may foster an environment in which orthorexic behaviors are normalized or even encouraged. Individuals may feel pressured to follow strict dietary guidelines in order to fit in or be perceived as healthy by their peers.
- Professional Expectations: Healthcare professionals, particularly those in nutrition and fitness-related fields, may feel pressured to demonstrate the healthy behaviors they encourage others to adopt. This pressure can lead to an unhealthy fixation on food and diet.
Environmental factors
- Access to Health Information: The widespread availability of health and nutrition information on the internet can be both beneficial and detrimental. While it enables people to make more informed diet decisions, it can also lead to misinformation and an overemphasis on certain dietary practices. Orthorexia patients may become fixated on specific diets or food trends that they believe are essential for good health.
- Food Environment: An individual’s risk of developing orthorexia can be influenced by their living environment. For example, living in an area with limited access to a variety of foods may result in an overemphasis on certain foods perceived as “healthy,” while avoiding others deemed “unhealthy.”
Symptoms and Behaviors of Orthorexia Nervosa
Orthorexia nervosa manifests as a variety of symptoms and behaviors that can have a significant impact on an individual’s life. These symptoms are typically psychological, behavioral, and, in some cases, physical.
Psychological symptoms
- Food Preoccupation: People with orthorexia obsess over food, planning meals, and researching nutritional information. This preoccupation can take over their thoughts and interfere with other aspects of their lives, such as work, relationships, and leisure time.
- Anxiety Around Food Choices: Orthorexic people frequently experience significant anxiety when making food choices, especially when eating out or in situations where they have less control over the food being served. This anxiety can cause social withdrawal and avoidance of food-related situations.
- Guilt and Shame: Deviating from their own dietary rules can result in intense feelings of guilt and shame. These emotions reinforce the rigid eating patterns associated with orthorexia, potentially perpetuating a cycle of restriction and punishment.
- Sense of Moral Superiority: Some people with orthorexia may develop a sense of moral superiority over others because of their eating habits. They may judge others’ eating habits and believe that a strict diet makes them more virtuous or disciplined.
Behavioral symptoms
- Rigid Dietary Rules: Orthorexic people frequently create and follow strict dietary rules that limit what foods they can and cannot eat. These rules may be based on preconceived notions about what constitutes a “healthy” diet, such as avoiding all processed foods, sugars, and fats.
- Avoidance of Social Situations: Because of their strict dietary rules and anxiety over food choices, people with orthorexia may avoid social situations involving food. This can result in social isolation and a breakdown in relationships with family and friends.
- Compulsive Checking of Ingredients: Orthorexics may obsessively check food labels and ingredient lists to ensure that the foods they consume meet their dietary requirements. This behavior can be time-consuming and obsessive.
- Food Group Elimination: People with orthorexia may gradually eliminate entire food groups from their diet, such as dairy, grains, or fats, because they believe these foods are unhealthy. This can cause severe dietary restrictions and nutritional deficiencies.
Physical symptoms
- Nutritional Deficiencies: Orthorexia’s strict dietary restrictions can cause significant nutritional deficiencies. Individuals who avoid entire food groups or specific nutrients may be deficient in essential vitamins, minerals, and macronutrients, resulting in a variety of health issues such as anemia, weakened immune function, bone density loss, and electrolyte imbalances.
- Weight Loss: While orthorexia is not primarily concerned with body weight, individuals with this condition may experience unintended weight loss as a result of their restrictive eating habits. This weight loss can sometimes be severe, resulting in malnutrition and other health issues.
- Gastrointestinal Issues: Orthorexia patients’ restrictive diets can cause gastrointestinal problems such as bloating, constipation, or irritable bowel syndrome (IBS). These problems may arise as a result of a lack of dietary diversity, a low fiber intake, or an overreliance on specific foods.
- Fatigue and Low Energy Levels: Because of insufficient caloric intake and nutritional deficiencies, people with orthorexia may experience chronic fatigue and low energy levels. This lack of energy can impair their ability to carry out daily tasks and attend social or professional events.
Orthorexia can cause hormonal imbalances, particularly in women. For example, restrictive eating patterns can result in amenorrhea (absence of menstruation), which is frequently associated with conditions such as anorexia nervosa. Men may also experience hormonal imbalances, which can have a negative impact on their overall health.
Effects of Orthorexia Nervosa
Orthorexia nervosa can have a significant impact on a person’s life, influencing not only their physical health but also their mental well-being, relationships, and overall quality of life.
Personal impact
- Mental Health Decline: The obsessive nature of orthorexia can result in a significant decline in mental health. Constant preoccupation with food and diet can aggravate anxiety, depression, and other mental health problems. The emotional toll of such a rigid lifestyle can result in feelings of isolation, loneliness, and low self-esteem.
- Impaired Social Life: Orthorexia frequently leads to social isolation because people avoid social gatherings, restaurants, and other situations where they can not control their food intake. This withdrawal from social activities can strain relationships with friends, family, and colleagues, resulting in a smaller support network.
- Decreased Quality of Life: An overemphasis on healthy eating can overshadow other aspects of life, such as hobbies, career goals, and personal development. The all-consuming nature of orthorexia can result in a lower quality of life, with the individual’s identity narrowly defined by their dietary habits.
Social and cultural impact
- The Impact of Social Media: Social media platforms play an important role in the spread of orthorexia. The promotion of “clean eating” and other dietary trends by influencers and celebrities can help to normalize extreme dietary practices. This influence can be especially powerful among young adults and teenagers, who are more vulnerable to societal pressures and trends.
- Public Health Concerns: Orthorexia poses a public health risk due to the possibility of widespread nutritional deficiencies and mental health issues. As awareness of the condition grows, so does the need for public health campaigns that promote balanced eating and challenge the notion that certain foods are inherently “bad” or “unhealthy.”
- Economic Impact: Orthorexia can result in healthcare costs associated with the treatment of nutritional deficiencies, mental health issues, and other related conditions. Furthermore, productivity losses caused by orthorexia’s physical and mental toll can have far-reaching economic consequences.
Orthorexia Nervosa and Other Eating Disorders
Orthorexia nervosa is similar to other eating disorders, such as anorexia nervosa and obsessive-compulsive disorder (OCD), but it also has unique characteristics that distinguish it.
Comparison to Anorexia Nervosa
- Focus on Food Quality vs. Quantity: Orthorexia is concerned with the quality of food, whereas anorexia nervosa is concerned with body weight and calorie restriction. Individuals with orthorexia are obsessed with eating “pure” or “clean” foods rather than simply limiting their caloric intake.
- Perception of Self-Control: Both conditions involve a sense of control over food, but the type of control varies. Anorexia controls quantity and weight loss, whereas orthorexia controls perceived healthiness and purity of food.
- Health Consequences: Both anorexia and orthorexia can have serious health consequences, including malnutrition and other health problems. However, the path to these outcomes differs, with orthorexia causing nutritional deficiencies by eliminating various food groups rather than just caloric restriction.
Comparison with Obsessive Compulsive Disorder
- Obsessive Behaviors: Orthorexia and OCD both involve obsessive behaviors, but in orthorexia, the obsession is focused on food and diet. Individuals with orthorexia may engage in ritualistic behaviors related to food preparation and consumption, similar to the compulsive rituals found in OCD.
- Anxiety and Control: Both conditions are motivated by anxiety and the desire for control. In orthorexia, anxiety is focused on the health consequences of food choices, whereas in OCD, anxiety can be related to a variety of fears and intrusive thoughts.
Orthorexia Nervosa and Healthcare Professionals
Healthcare professionals play an important role in diagnosing and treating orthorexia nervosa. However, because the condition has yet to be officially recognized in diagnostic manuals such as the DSM-5, healthcare providers may find it difficult to diagnose and treat.
Challenges in Diagnosis
- Lack of Official Criteria: Because orthorexia has no official diagnostic criteria, it is frequently overlooked or misdiagnosed as another eating disorder. This can delay appropriate treatment and worsen the condition.
- Overlap with Healthy Eating: Because orthorexia includes behaviors that are generally considered healthy, such as eating nutritious foods and avoiding processed foods, healthcare providers may struggle to distinguish between a healthy diet and a disordered eating pattern. This overlap can make it difficult to determine when a patient’s focus on healthy eating has become obsessive and harmful.
Role of Education and Awareness
- Increased Awareness: Healthcare professionals must be aware of the signs and symptoms of orthorexia in order to provide appropriate care. This includes an understanding of the disorder’s psychological and behavioral components, as well as the physical health implications.
- Patient Education: Educating patients on the benefits of a balanced diet and the dangers of extreme dietary restrictions is critical for preventing and treating orthorexia. Patients should be encouraged to see food as a source of nourishment and enjoyment, not something to be controlled or feared.
