Summary: Individuals aged at least 65 years are a fast-growing segment of the population. Age-related loss of muscle mass and strength will continue to have a significant economic impact unless dietary or exercise interventions are implemented. Increasing the ratio of animal-based protein relative to plant-based protein in the diet may help to mitigate age-related losses of muscle mass and strength. Animal-based protein sources, especially those that are lean or nutrient dense, are the most anabolic per gram. Additional health and environmental considerations are needed prior to increasing animal-based protein intake recommendations in the United States and globally.
