About

The goal of this study is to evaluate the effects of beef consumption on cognitive and brain health in healthy young adults. Specifically, we seek to evaluate the effects of beef consumption on measures of executive function, memory, psychological well-being, and sleep quality. Additionally, we will explore the effects of increased beef consumption on measures of brain health derived from structural and functional brain imaging.

All participants will take part in a 12-week dietary intervention study. Throughout the intervention, participants will receive 5 portions of ready-to-eat beef in frozen packages each week. Each serving of ready-to-eat beef for the experimental group will weigh 5-ounces, while each serving of ready-to-eat beef for the comparison group will weigh 1-ounce. Study compliance will be evaluated through weekly surveys about beef consumption.

In addition to completing the dietary intervention, participants will complete pre- and post-intervention assessments:

  • MRI scan, including structural and functional brain imaging
  • a comprehensive questionnaire battery evaluating cognitive and psychological measures
  • neuropsychological tasks
  • a blood draw
