Plant-based proteins may require higher intake to match muscle growth of animal sources
In short: Researchers exploring sports nutrition have observed that consuming plant-derived proteins, such as soy or wheat, often results in lower muscle protein synthesis compared to eating the same amount of animal-based protein. This difference is likely due to the way plant proteins are digested and their specific amino acid profiles, which often lack essential components like lysine or methionine.
The study highlights that while plant proteins are less anabolic, these effects might be offset by consuming larger quantities, using protein blends to balance amino acids, or fortifying sources with specific nutrients. However, the authors note that few direct human trials have compared these specific responses, and more clinical research is needed to establish exact dietary requirements for plant-based athletes.
Why it matters: Switching to a plant-based diet may require adjusting protein quantity or variety to maintain muscle health.
