Study Details

Study Description

Brief Summary

This will be a randomized study to determine if animal-based protein-rich food sources can stimulate greater muscle protein turnover and whole-body protein balance and reduce skeletal muscle inflammatory markers in postmenopausal women compared to vegetarian base protein-rich foods.

Condition or Disease Intervention/Treatment Phase
  • Other: meals consisting of primarily animal protein sources
  • Other: meals consisting of plant protein sources
N/A

Detailed Description

A randomized cross-sectional controlled trial will be conducted to quantify whole-body and muscle protein turnover and skeletal muscle inflammation following 5-days of consumption of either beef or isonitrogenous plant-based sources of protein in normal/overweight and obese post-menopausal females. A premenopausal normal/overweight group consuming beef containing study meals will also be recruited to serve as a healthy control comparison.
