Not all dietary proteins are created equal. Protein quality is a measure of dietary protein that considers not just the amount of essential amino acids a food protein provides but also how effectively the body can digest, absorb, and utilize those amino acids. With the global population projected to reach nearly 10 billion by 2050, the demand for sustainable, high-quality dietary protein will grow significantly. Given this increasing demand, accurate protein quality assessments are more critical than ever.
Driven by the need to help ensure nutritional security within planetary boundaries, Global Dairy Platform coordinated Project Proteos, a six-year study involving researchers from four laboratories on three continents, to determine the Digestible Indispensable Amino Acid Score (DIAAS) values of local foods. This was in response to a report published by the Food and Agriculture Organization (FAO) of the United Nations calling for the need to replace the Protein Digestibility Corrected Amino Acid Score (PDCAAS) method for evaluating protein quality for humans with the DIAAS method because DIAAS offered a more complete measure of protein quality. One of the challenges to replacing PDCAAS with DIAAS included having data on the DIAAS values of foods. The results of Project Proteos, the last of which were published in 2024, are being used to populate a FAO database of amino acid contents and DIAAS values of foods to fill that gap and inform future policies and programs aimed at using protein quality to help ensure nutritional security.
This webinar, presented by Dr. Hans Stein, University of Illinois, USA, and Dr. Isidra Recio, Instituto de Investigación en Ciencias de la Alimentación, Madrid, Spain, will provide attendees with an overview of the importance of protein quality to global human health and an update on what’s next for protein quality in research and policy.
