Rosan Meyer and Luise Marino put together a Q&A to introduce the topic of avoidant restrictive food intake disorder (ARFID).
Avoidant restrictive intake food disorder (ARFID) is an eating disorder affecting in particular food variety, that may lead to nutritional deficiencies, first recognised in the DSM-V criteria in 2013 affecting all age groups.1
Factors associated with the development of ARFID include:
ARFID is different from eating disorders such as anorexia, bulimia, or OSFED, as individuals are not restricting their intake with the purpose of losing weight. ARFID sufferers do not usually have body dysmorphism or employ over-exercising to control their weight.3, 4
Individuals with ARFID, particularly children, have increased nutritional risk as eating patterns such as reduced food variety and intake can result in macro- and micronutrient deficiencies and growth faltering. In some cases this may require artificial nutrition support either as a naso-gastric tube feeds or oral nutritional supplements,5 impacting on the quality of life of the child and the family.3, 6 A recent qualitative systematic review of case reports/case series of ARFID associated with autism, found that 69.7% of published cases involved scurvy (vitamin C deficiency), followed by 17.1% involving eye disorders secondary to vitamin A deficiency. Other micronutrient deficiencies reported included vitamins D, B12 and thiamine. In addition, 69.2% of patients had a body mass index or weight for age percentile within normal range.7, 8

Management strategies for ARFID continue to evolve but include nutritional, psychological, sensory-motor and medical assessment, followed by plans focusing on:
Future qualitative research should also consider the development of patient-centred definitions of recovery from the perspective of individuals, families and HCPs.5, 9
ARFID is not someone with picky or mildly selective eating.1, 6, 7 There are many brave and eloquent posts on the internet describing the holistic effect ARFID has on individuals and families. Even young children are able to articulate how food makes them feel: “I want to eat but my mind won’t let me,” said Isla, aged four, and: “Food is scary and makes me feel shaky,” said Matthew, aged seven.
An adult ARFID sufferer explained: “I remember living in a constant state of hunger, fear, and isolation. If I had to sum up ARFID in just one concept it would be that: isolation. Food is such a big part of how humans connect to each other, and I kept missing out on that. I felt terribly isolated, embarrassed about myself, and worst of all, impotent.” (From a Medium blog by @Semirasis)
In September 2020, we launched a short survey to better identify what knowledge and information HCPs felt they need to have in order to feel confident in diagnosing and providing care and support for individuals with ARFID, as well as being a reference source for parents of children with ARFID.
We had 128 respondents, of which 45% were dietitians with 33% working in community trusts. Almost half of respondents had more than 10 years’ experience in their current role.
More than 75% of respondents wanted background information relating to diagnosis and the difference between ARFID, autism and other eating disorders was essential. Assessing nutrition risk was considered to be of high importance to 50% of respondents with regards to understanding:
Aspects relating to the nutrition care plan considered to have high importance were:
Free text comments included signposting resources for HCPs/parents and diagnosis, management and recovery.10
