The purpose of the study is to determine the effects of peanuts on cognitive performance and task-related brain activation on functional magnetic resonance imaging (fMRI) in older adults. The specific aim of the study is to explore the neuroprotective effects of a peanut-enriched diet (2-3 oz of peanuts to replace 20% of the total energy of the habitual diet) for 12 weeks compared to a peanut-excluded habitual diet in elderly men and women with increased risk for CVD and self-reported memory complaints. The study population is older adults 60-80 years in age.
The study will test the effects of Peanuts on task-related brain activation and cognitive functions in older adults with memory complaints.
