What this trial studies
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.
Conditions in scope
- Menopause Related Conditions
Interventions
- meals consisting of primarily animal protein sources (Other) — an omnivorous diet
- meals consisting of plant protein sources (Other) — an herbivorous diet
