Is ARFID the same as picky eating?
When picky eating is severe, it is diagnosed as ARFID. Known as “extreme picky eating,” It is an eating disorder that can be as harmful to health as its more widely known eating disorders, anorexia, and bulimia. Traditionally thought to only occur in children, it is now on the rise in adults.
Often, people with ARFID will say they are not hungry, do not think about food, and can even forget to eat because food is not a priority. In contrast, picky eaters do often feel hungry, are interested in eating the foods they enjoy, and do not have the same lack of interest in food and eating.
The types of ARFID include: Avoidant, Aversive, Restrictive, Adult ARFID and ARFID “Plus.”
While they can both manifest in similar ways, ARFID is an eating disorder, while SPD is a neurological disorder. But, both conditions can lead to issues such as picky eating habits which can make them difficult to differentiate.
3 ARFID is described by some as “food neophobia,” where difficulty with novelty leads to a limited diet. Parents often report that their children with ARFID had trouble transitioning to mixed foods from single baby foods. They also often report they had a specific sensitivity to textures such as “mushy” or “crunchy.”
While not everyone on the autism spectrum will have ARFID, and vice versa, it's estimated that up to a third of people with ARFID are also autistic.
Types of feeding problems associated with autism
The feeding concern most commonly observed in children with autism is food selectivity, or eating a limited variety of foods. This most often involves preference for starches and snack foods and more frequent rejection of fruits and vegetables.
Avoidant Restrictive Food Intake Disorder (ARFID) is a new diagnosis in the DSM-5, and was previously referred to as “Selective Eating Disorder.”
The best evidence suggests that about 0.3% of people 15 years old and older have ARFID. Rates of ARFID in adults could be much higher in people with gastrointestinal (GI) issues. A study of adults who presented for a GI evaluation found: 23.6% of people had some symptoms of ARFID.
ARFID, sometimes known as “extreme picky eating,” is also linked to attention deficit hyperactivity disorder (ADHD), autism, and other conditions.
Is ARFID Neurodivergent?
A neurodivergent person may experience ARFID. ARFID can also be considered a form of neurodivergence on its own. ARFID, ADHD, Anxiety and Depression can all change the way a person thinks and experiences the world.
Turns out, there's no single explanation for your picky eating habits, but rather, experts suggest a combo of genetics and environment are to blame. Picky eaters are typically unwilling to try new foods, which can be the result of your DNA and your upbringing. Marcia Pelchat, Ph.
Kids with ARFID are more likely to have: anxiety or obsessive-compulsive disorder (OCD) autism spectrum disorder or attention deficit disorder (ADHD) problems at home and school because of their eating habits.
A recent systematic review of case reviews of patients with both ARFID and autism, found that almost 70% of those with ARFID had scurvy (vitamin C deficiency), while 17% had eye disorders as a result of vitamin A deficiency. Vitamin D, B12, and thiamine deficiencies were also reported.
And unlike your average picky eater, people with Arfid may only eat less than 20 different types of food – typically “white” or “beige” foods, such as bread, boiled rice and crackers. This can lead to weight loss or growth faltering in children, deterioration of psychological function, and nutritional deficiencies.
Food neophobia is generally regarded as the reluctance to eat, or the avoidance of, new foods. In contrast, 'picky/fussy' eaters are usually defined as children who consume an inadequate variety of foods through rejection of a substantial amount of foods that are familiar (as well as unfamiliar) to them.
While someone with ARFID may be obsessive about avoiding eating food, sometimes a person experiences both ARFID and OCD. In some cases, the two disorders can appear similar, but when someone has both conditions, they will meet the distinct diagnostic criteria for each disorder.
ARFID, like all eating disorders, likely has complex neurological and biological underpinnings. It is not a choice. Also like other eating disorders, there is not a single cause of ARFID.
Dr. Bulik leads research teams at UNC-Chapel Hill and the Karolinska Institutet Centre for Eating Disorders Innovation. The researchers discovered that the genetic component for developing ARFID was high, 79 per cent. This means that 79 per cent of the risk of developing ARFID are explained by genetic factors.
- Difficulty understanding social norms and social rules.
- Inappropriate behaviour in social settings and situations.
- Difficulty predicting others reactions, thoughts and behaviours.
- Lack empathy towards others.
- Difficulty making and maintaining friendships.
Are picky eaters born or made?
It appears it be both. Some estimates claim 78% of picky eating is due to heritable or developmental characteristics – how the taste buds and smell centers of the brain perceive flavour and how a child's taste is designed to mature with time.
High-functioning autism usually refers to people with autism who have no intellectual disability, or delay in verbal speech development, and whose symptoms of autism has less of an impact on their daily life. Learn more.
ARFID Take Home Points:
ARFID is often associated with anxiety and obsessive-compulsive disorder. ARFID is more than just “picky eating;” children do not grow out of it. Left untreated, they may become malnourished. The true prevalence of ARFID is still being studied, but it may affect as many as 5 percent of children.
What is the difference between a “Picky” Eater and a “Selective” Eater? Picky eaters may eat a limited number of foods but they eat at least one or two foods from each food group. They have more balanced diets than selective eaters. Selective eaters have aversions to many more foods, or have unusual aversions.
ARFID is similar to anorexia in that both disorders involve limitations in the amount and/or types of food consumed, but unlike anorexia, ARFID does not involve any distress about body shape or size, or fears of fatness.
