Does Increased Egg Consumption Have Cognitive and Neural Benefits in Food Insecure, At-risk Adolescents?

Not Applicable

Completed

• Conditions: Adolescents With Food Insecurity
• Interventions: Other: Typical diet; Other: Increased Egg Consumption

• Registration Number: NCT03951883
• Lead Sponsor: Texas Tech University

Brief Summary

Quality nutrient intake is essential for proper development and well-being of children in all aspects of health, including cognitive development. Eggs are of particular interest based on potential cognitive and neurological benefits due in part to significant concentrations of choline and lutein. While overall, choline and lutein have received considerable attention in the literature in relation to cognition and brain function, most studies involving intake in young adults have had short intervention periods ranging from 90 minutes to 3 days. Food insecurity has been associated with decreased academic performance. Given that populations with food insecurity have limited resources to direct towards nutrition, identifying how a widely available, highly versatile and largely affordable source of nutrients (i.e. eggs) may have favorable impacts on cognitive function and brain function will be valuable in informing public health recommendations in this at-risk population. As such the investigators will examine whether an increased egg consumption dietary prescription can have positive effects on functional activity (i.e. fMRI) during an Eriksen-Flanker task, anatomical changes in the brain (i.e. DTI, MRI), and cognitive abilities as measured by the Stop Signal Reaction Time task, Operation Span task, Raven's Progressive Matrices and the Boston Naming Task.
