Eating disorders are often associated with an obsession to lose weight or achieve a certain body image. However, there is a lesser-known eating disorder that has nothing to do with weight concerns but is driven by a deep-seated fear of food itself. This disorder is called Avoidant/Restrictive Food Intake Disorder (ARFID), a condition characterised by an aversion to eating that can be triggered by anxiety or specific sensory characteristics of food.
What is ARFID?
Avoidant/Restrictive Food Intake Disorder (ARFID) is a recently recognised eating disorder that is not linked to body image or weight loss goals. Instead, individuals with ARFID experience anxiety or fear related to food intake, often fearing that consuming certain foods could lead to choking or other negative consequences. This fear often causes them to restrict their diet severely, which can have significant health implications if left untreated.
Unlike other eating disorders, such as anorexia or bulimia, ARFID does not stem from a desire to lose weight. People with ARFID may limit their intake because of perceived dangers or undesirable qualities associated with food, such as its colour, taste, texture, or smell. This means that their aversion to food is more focused on the sensory aspects of eating rather than a concern about calories or body size.
ARFID vs. Picky Eating
At first glance, ARFID might be mistaken for extreme picky eating, especially in children. However, there are crucial differences between the two. Picky eating, which is relatively common during childhood, usually lessens as a child grows older and is typically not harmful to health. Children who are picky eaters may refuse certain foods but will still consume a reasonably balanced diet over time.
In contrast, ARFID can persist throughout childhood into adulthood and is much more severe than picky eating. Individuals with ARFID may avoid entire food groups, resulting in insufficient nutrient intake, which can lead to malnutrition, weight loss, or other serious health issues. This long-term avoidance makes it a far more dangerous condition than typical picky eating and requires medical intervention.

Causes of ARFID
The exact causes of ARFID are still under research, but several factors appear to contribute to its development. Psychological elements, such as anxiety and fear, play a significant role. Many individuals with ARFID have an intense fear of choking, vomiting, or experiencing a negative reaction to food, which causes them to avoid certain items altogether.
Additionally, social, environmental, and cultural factors can contribute to the onset of ARFID. Traumatic experiences involving food, such as being force-fed or facing food insecurity, can trigger the disorder. Genetic predisposition also seems to be a factor, particularly in families with a history of eating disorders or mental health conditions like anxiety or depression. Developmental conditions, including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, and sensory processing disorders, are also linked to a higher likelihood of developing ARFID.
Who is at Risk?
While ARFID often emerges during childhood, it can affect individuals of any age. Children are particularly vulnerable, but teenagers and adults may also develop the disorder, especially if they have had negative experiences involving food. People who have faced traumatic feeding situations, such as being pressured to eat or experiencing severe food insecurity, may be at higher risk.
Additionally, individuals with a family history of mental health conditions, such as depression or anxiety, are more likely to develop ARFID. Those diagnosed with neurodevelopmental disorders, such as autism or ADHD, also have a higher propensity for the disorder due to increased sensitivity to sensory stimuli like food textures, smells, and colours.

Symptoms of ARFID
The symptoms of ARFID can vary, but most individuals display a noticeable avoidance of certain foods based on their sensory characteristics. Common signs include significant weight loss, nutrient deficiencies, and complaints of digestive issues, such as abdominal cramps, upset stomach, or constipation. Because individuals with ARFID often fail to consume enough calories or a diverse range of nutrients, they may also experience fatigue, dizziness, and other signs of malnourishment.
In children, ARFID can result in stunted growth or developmental delays if the condition is left untreated for an extended period. Adults with ARFID may also experience similar health challenges, with the added risk of long-term complications such as weakened immune function or the development of chronic health conditions.
Bottomline: The Importance of Early Intervention
ARFID is a complex eating disorder that extends beyond the realm of traditional food aversions or picky eating. The intense fear associated with eating can severely impact physical health, leading to malnutrition, weight loss, and other life-threatening complications. Since ARFID typically persists without treatment, early diagnosis and intervention are crucial for managing the disorder effectively.
Treatment approaches for ARFID may include cognitive-behavioural therapy, exposure therapy, and working with nutritionists to reintroduce feared foods into the diet in a safe, controlled manner. With proper care and support, individuals with ARFID can work towards overcoming their fear of food and restoring their nutritional health.
