Dietary Intervention in Cognitive Aging

Start: January 2016
End: July 2023
Enrollment: 250

What Is This Study About?

This study will test whether a carbohydrate-restricted diet combined with berry fruit supplements improves memory and metabolism (how fast the body burns calories) in overweight, older adults with memory problems. Participants will be randomly assigned to a carbohydrate-restricted or high carbohydrate diet combined with either a berry fruit supplement or a placebo for 12 weeks. Researchers will measure changes in cognition, memory, metabolism, including insulin resistance. The results of the study will help inform the development of interventions that may slow the progression of cognitive decline for people at higher risk.
