Reducing ultra-processed foods to improve attention and thinking in children with ADHD
Relationship Between Ultra-processed Food Consumption and Behavioral Disorder and Cognitive Function in Children and Adolescents: the Mediation Role of Plasticizer
This program will try an online nutrition course to see if cutting back on ultra-processed foods helps thinking and attention in 10–15-year-olds with ADHD or attention difficulties.

What this trial studies
This interventional program enrolls 10- to 15-year-olds with diagnosed ADHD or identified attention/learning difficulties who regularly consume multiple ultra-processed foods daily. Participants are assigned to a 12-week, weekly online nutritional education course that encourages replacing ultra-processed foods with whole foods, or to a non-intervention comparison group. Cognitive function and attention measures are compared between groups to determine whether reduced ultra-processed food intake leads to improvement. Dietary intake and adherence are monitored through parent/participant reports during the intervention period.
Who should consider this trial
Good fit: Ideal candidates are 10–15-year-olds diagnosed with ADHD or identified as having attention/learning difficulties who consume at least six types or six servings of ultra-processed foods daily.
Not a fit: Children outside the 10–15 age range, those who do not regularly consume ultra-processed foods, or those whose attention problems stem mainly from non-dietary medical causes may be unlikely to benefit.
Why it matters
Potential benefit: If successful, reducing ultra-processed foods could improve attention and cognitive functioning in affected children and adolescents.
How similar studies have performed: Observational studies have linked high ultra-processed food intake to poorer cognition and behavior, but randomized interventions in young people with ADHD are limited.
