Macro partitioning

Increasing the dose of plant-based protein (e.g., 60g wheat) or blending complementary plant proteins (e.g., maize/soy) can overcome the inferior anabolic response of single plant sources in older adults, matching the efficacy of animal proteins.

If you eat plants, don't just eat a small scoop of protein powder. You need to eat more of it to get the same muscle-building signal as meat. Try mixing different plant proteins (like rice and pea) to get a better balance of amino acids, or ensure you are getting enough total protein at each meal to hit the leucine threshold.

ModerateQualifiesMEDIUM confidence
Ingesting a greater amount of wheat protein (i.e. 60 g), matched for the leucine content of whey protein, prolonged the postprandial increase in plasma leucine concentrations and increased muscle protein synthesis rates to a similar extent as casein.

Why this rating

Based on acute metabolic studies; long-term chronic data for these specific high-dose plant strategies in older adults is less robust than for animal proteins.
