Effects of ultra-processed foods on hunger and brain function
Elucidating the Relationship Between Ultra-Processed Food Consumption, Executive Function, and Hunger-Related Hormones
This study is testing how eating only ultra-processed foods for three days affects hunger and brain function compared to eating unprocessed foods for three days in adults.

What this trial studies
This study investigates how a diet consisting of ultra-processed foods (UPF) affects hunger-related hormones and executive function in adults. It employs a two-arm, crossover, randomized controlled design, where participants will consume an entirely ultra-processed diet for three days followed by an entirely unprocessed diet for another three days. The aim is to assess the differences in hormonal responses and cognitive performance between the two dietary patterns.
Who should consider this trial
Good fit: Ideal candidates for this study are healthy adults aged 18-55 who can adhere to the dietary requirements.
Not a fit: Patients with chronic diseases, special dietary needs, or visual impairments may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide insights into how dietary choices impact cognitive functions and hunger regulation.
How similar studies have performed: While there is ongoing research into the effects of diet on cognitive function, this specific approach focusing on ultra-processed versus unprocessed foods is relatively novel.
