Individuals who follow a diet that is restricted in range are often referred to as ‘Picky Eaters’ (PEs) which is a rather vague term, frequently used to describe a broad array of eating practices, including those who are fussy eaters and less willing to try new foods (Neophobia).  At the clinical level PE forms one of the central aspects of the DSM classification for Avoidant/Restrictive food Intake Disorder (ARFID) (DSM-5, APA).  Work on the prevalence of ARFID in the UK are rare but one recent report estimated this to be between 4 and 11pct  (Nicholls-Clow et al., 2024) and therefore represents a substantial number of individuals.  Following a restricted eating regime can lead to deficiencies in a number of nutrients including in iron and zinc (Taylor & Emmett, 2019), and possibly as a consequence, increased health risk (AHA, 2020).  There are also impacts in other areas including the social aspect of eating, where PEs can often feel anxious when eating with others (Barnhart et al., 2021), which could be exacerbated in an era of adventurous eating experiences, shared on television and social media.  Whilst research has examined this phenomenon extensively in children, there remains a lack of knowledge in terms of adult PEs.  The aim of the project is therefore to further explore the relationship between adult non-clinical PE and other behavioural traits such as Neophobia and Orthorexia and understand the experiences of those who see themselves as PEs.  Additionally, linking to recent work (Annette & Stafford, 2023), to examine whether strategies can be developed to enhance and potentially broaden the range of foods that PEs consume.
