Effects of Peanut Intake on Cognitive Functions

Effects of Peanut Intake on Task-related Brain Activation and Cognitive Functions in Older Adults With Memory Complaints: A Randomized Controlled Study

The study will test the effects of Peanuts on task-related brain activation and cognitive functions in older adults with memory complaints.

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.

Inclusion Criteria:

• Non-demented elderly between 60-80 years of age
• Self-reported memory complaints
• Two cardiovascular risk factors
• Stable weight for at least 6 months prior to recruitment

Exclusion Criteria:

• Peanut allergy
• Smoker
• Endocrine, metabolic and neuropsychological disorders
• Ineligible to get an MRI
• Consuming more than 3 servings/week of nuts including peanuts
