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.
Key Takeaways
Animal protein sources contribute to increased muscle growth per gram than plant based protein sources. Eating more animal protein will have a more beneficial effect at reducing age related decline of muscle mass and strength.
