Brief summary

The goal of this interventional study is to determine whether reducing ultra-processed food consumption in children and adolescents can improve cognitive function. The main question it aims to answer is: Does reducing ultra-processed food consumption through online nutritional education improve cognitive function in children and adolescents with attention difficulties? Researchers will compare a nutritional education group to a non-intervention group to assess whether reducing ultra-processed food intake leads to cognitive improvement. Participants will: Attend a weekly online nutritional education course for 12 weeks Be encouraged to replace ultra-processed foods with whole foods

Design outcomes

Primary

Measure	Time frame	Description
Cognitive function	Baseline and after the intervention (at 12 weeks)	Cognitive function will be assessed using selected tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB), covering multiple cognitive domains. CANTAB does not provide a single total score; each task generates task-specific outcome measures. Higher accuracy scores and lower reaction times or error rates generally indicate better cognitive performance.
