What the study is about

The goal of this clinical trial is to learn if eating more beef will lead to better cognition and a healthier brain in younger adults. The main questions it aims to answer are:

  • Does eating more beef lead to higher scores on cognitive tests and better quality of life?
  • Does eating more beef lead to better brain function?

Researchers will compare participants in the experimental group (participants who will eat 25 ounces of beef every week during the dietary intervention) to control participants (participants who will eat 5 ounces of beef every week during the dietary intervention).

Participants will

  • Be instructed to prepare and consume ready-to-eat beef meals along with their regular diet and not eat any more beef other than what they are given
  • Visit the study facilities once every week to pick up ready-to-eat beef meals; and complete a brief survey every week to track their consumption of the provided beef meals, and a dietary survey every 4 weeks
  • Visit the study facilities before and after the 12-week of intervention period for researchers to study them

Being studied: Ready-to-eat beef in frozen, 5-oz packages; Ready-to-eat beef in frozen, 1-oz packages

Conditions: Dietary Intervention; Dietary Proteins; Dietary Assessment; Cognitive Ability, General
