Aim It has been suggested that adolescents diagnosed with ADHD have an unhealthier diet compared to their peers without ADHD. The association between chemosensation (smell and taste) and dietary patterns remains unknown. The aim is to investigate unhealthy food preferences and food neophobic behaviour among adolescents diagnosed with ADHD. Additionally, it is to investigate the relationship between dietary patterns and chemosensory function. Methods We enrolled 36 adolescents with and without ADHD to complete a food item and a food neophobia questionnaire and to undergo chemosensory testing. Results Adolescents with ADHD performed significantly worse on both chemosensory tests compared to the non‐ADHD group. No difference in food preferences nor food neophobia was found between the two groups. Conclusion Adolescents with ADHD have a lower score on chemosensory tests compared to their peers, suggesting impaired chemosensory function. No differences in dietary preferences nor food neophobia were seen between the two groups.

Aim Better understanding of aspects of taste in adolescents is needed since it has bearings on food policies, food industry and pharmaceutical design. Furthermore, taste preferences likely play a role in overeating and anorexia. We aimed to validate a questionnaire about taste preferences and dietary habits along with measurements of sense of smell and taste. Methods We included adolescents from nearby schools in Aarhus, Denmark, from 2017 to 2019. Scoring preferences and habits on a Likert scale, they completed a food item questionnaire. Their chemosensation was tested by the Sniffin’ Sticks and Taste Drop Test. Results We included 100 adolescents: 53 males, 47 females; average age: 15.9 years (12‐17 years). Retest of the questionnaire showed good reliability (Cohen's kappa: 0.5953). Snacks scored the highest average liking (4.48), whereas starches had the highest frequency of consumption (3.64). Bitter taste threshold was positively associated with liking and familiarity with vegetables (P = .032; P = .012), respectively. Healthy self‐reported dietary habits were associated with a higher self‐reported consumption of vegetables and a decreased consumption of snacks. Conclusion Adolescents preferred unhealthy food items, but they also reported more frequent consumption of healthy than unhealthy food items. A higher threshold for the bitter taste, that is, being less sensitive to bitter taste, was associated with higher liking and familiarity of vegetables.
