Core Viewpoint - The article highlights the rising concern of "orthorexia," a condition characterized by an unhealthy obsession with healthy eating, particularly among adolescents, leading to severe health issues such as heart damage and eating disorders [3][5]. Group 1: Case Study - A 14-year-old girl, referred to as Xiaoxi, developed orthorexia after being teased about her weight, leading her to adopt extreme dietary restrictions that resulted in significant health problems, including hair loss and fainting due to low blood sugar [1][2]. - After receiving treatment that included cognitive behavioral therapy and nutritional support, Xiaoxi began to relax her strict dietary rules and returned to a more balanced diet [2]. Group 2: Definition and Characteristics - Orthorexia, first introduced by Dr. Steve Bratman in 1997, is defined as a pathological obsession with "pure" and "healthy" foods, differing fundamentally from other eating disorders like anorexia and bulimia, which focus on food quantity or weight [3][5]. - Individuals with orthorexia often create strict dietary rules, avoid certain food groups, and experience anxiety when these rules are broken, leading to a narrow food selection and excessive time spent on meal planning [4][5]. Group 3: Contributing Factors - The article identifies three key factors contributing to the rise of orthorexia among adolescents: 1. **Appearance Anxiety and Social Media Influence**: Adolescents are highly sensitive to body image, and social media promotes extreme dieting as a desirable behavior [7]. 2. **Family Environment**: Parents' overemphasis on health and body image can lead children to associate food control with safety and security [8]. 3. **Psychological Needs**: Adolescents may use food control as a coping mechanism for anxiety related to academic and social pressures, leading to obsessive behaviors [9]. Group 4: Warning Signs and Interventions - Warning signs of orthorexia include increasingly strict dietary rules, avoidance of social gatherings due to dietary restrictions, and physical symptoms such as significant weight loss and fatigue [10][11][12]. - Recommended interventions include empathetic communication, restructuring dietary perceptions to promote variety, reducing exposure to extreme dieting content, and seeking professional help if symptoms persist [13].
