Summary : Protein quality for human nutrition is an old issue but the various methods aiming to assess protein quality have been criticized on theoretical and methodological ground. For the last years, stable isotope tracer-based methods in the postprandial state in humans have produced important progress. These refined techniques are strongly theoretically sounded for assessing protein quality and gaining further insight on the underlying concept. These methods have shown that protein sources exhibit global differences in protein quality in humans with adequate nutritional status that are far lower than expected based on usual methods. However, the nature of the dietary proteins could have some more subtle impact on tissues or secondary individual amino acid metabolic pathways, the final physiological and functional consequences of which will need to be evaluated. |
