The lower quality of plant-based proteins implies that the total amount of protein consumed must be increased to meet the body's requirements.

This analysis is based on a study (PMID: 31835510) that examines the digestibility and amino acid profiles of plant-based sources compared to animal-based sources. It is scientifically established through nutritional consensus (meta-analyses and literature reviews) that plant-based proteins are often less 'complete' or less bioavailable due to antinutritional factors or lower contents of essential amino acids such as leucine. The advice is therefore accurate: to achieve equivalent protein synthesis, a slightly higher intake or the diversification of plant-based sources is recommended. What is sometimes exaggerated in wellness discourse is the idea of an intrinsic 'inferiority,' when it is simply a matter of quantitative and qualitative adjustment. There is no evidence that a vegetarian diet is incapable of supporting health or performance, provided that this difference in digestibility is compensated for. The point is biologically sound.
