CAST papers are developed by interdisciplinary task forces composed of volunteer authors, chairs, reviewers, liaisons, and translators from academia, industry, and government. This index recognizes those contributors and highlights the breadth of expertise that supports CAST’s work.

Bio

Distinguished Professor Paul James Moughan is an acclaimed New Zealand scientist widely recognized for his contributions to science, university leadership and international advocacy.

Professor Moughan graduated PhD from Massey University in the area of mammalian protein metabolism in 1984. His early research career focused on digestive physiology and the mathematical modelling of amino acid digestion and metabolism in monogastric species of animal, especially avian, porcine, feline and human. Over the last 20 years he has led a systematic discovery-based research programme into the effects of diet on gut metabolism and digestion and, amongst other discoveries, is credited with establishing the role of food peptides in influencing gut protein metabolism. He has also made significant contributions to knowledge in the chemical analysis of foods and the development of bioassays of nutrient availability. The latter have had considerable application in practice. He is widely regarded as a world authority on mammalian and human protein metabolism and food evaluation science. He is a world leader in the field of protein quality evaluation. Professor Moughan has published >500 works of scholarship.

CAST_Protein-in-the-Diet
Protein quality, not just quantity, is critical for meeting human dietary needs. This paper reviews animal‑, plant‑, and emerging protein sources in terms of amino acid composition, digestibility, nutritional adequacy, and environmental impact. It highlights life‑stage–specific protein requirements, limitations of single‑source proteins, and the role of complementary proteins in balanced diets. Global patterns of protein availability, future demand, and sustainability challenges are examined. The paper concludes that diverse dietary protein sources, rather than exclusive reliance on plant or animal proteins, are essential for supporting human health and resilient food systems.
