Book (stand-alone)Development of a protein database and the way forward for reviewing protein requirements
Report of a joint FAO/IAEA technical meeting in Vienna, 10–13 October 2022

No results found.Providing an adequate, sustainable, and nutritious supply of protein remains an increasing challenge in the light of changing food systems and raised levels of food insecurity and malnutrition. A joint FAO and IAEA technical meeting was held in Vienna, in 2022, to discuss the development of a protein quality database and the revision of protein requirements across population groups. Participants updated evidence and related methods on protein requirements and protein quality assessment and designed a framework for the development of a protein digestibility database to aid dialogue on the evaluation of protein quality and protein sufficiency in different populations. The report of this meeting offers a global presentation of the concept of protein quality and requirements throughout the life course. It presents the important elements needed to set protein requirements, such as indispensable amino acid scores and indispensable amino acid reference patterns and the associated methods. The report then narrows down on assessment of protein digestion and metabolic utilization and related assessment methods, including stable isotope tracer techniques. Finally, the report summarizes the framework for a new protein quality database jointly managed by FAO and IAEA, which was agreed on by experts at the technical meeting.The report also recognizes the dearth of data on protein quality from low- and middle-income countries and recommends that resources be mobilized to set up a protein quality database, inclusive of data on climate-smart foods. -
DocumentResearch approaches and methods for evaluating the protein quality of human foods
Report of a FAO Expert Working Group, 2 – 5 March 2014, Bangalore, India
2014Also available in:
No results found.Following the 2011 FAO Expert Consultation on dietary protein quality evaluation in human nutrition, a working group was convened in Bangalore, India from 2-5 March 2014 to explore and develop means for producing more data accessible worldwide of ileal amino acid digestibility of human foods, particularly for foods consumed in low income countries. The paucity of data, especially from human studies, remains an obstacle to the practical implementation of the DIASS method for evaluating protein qu ality. The report considers protocols including recommended best practice for pig-based, rat-based and human based assays for true ileal amino acid digestibility determinations to support the generation of new data. The working group considered the development of protocols that would allow non-invasive measures of ileal amino acid digestibility in humans with primary reliance on novel approaches using minimally invasive stable isotopes tracers. Such an exercise would need to involve the determin ation of ileal protein and amino acid digestibility in both humans and animal models to allow the development of robust inter-species protein digestibility predictions. -
BookletGuidelines for ready-to-use therapeutic foods 2023
Also available in:
No results found.This text provides guidance on technical and nutritional aspects of the production of ready-to-use therapeutic foods (RUTF) including nutritional composition, raw materials and ingredients, good manufacturing practices, microbiological and chemical contaminant criteria, methods of analysis and sampling, and provisions for packaging and labelling. The provisions of these guidelines apply to RUTF for children aged from 6 to 59 months with severe acute malnutrition (SAM) who need efficacious and timely intervention including safe, palatable foods with a high-energy content and adequate amounts of vitamins, minerals and other nutrients within an appropriately designed programme that promotes continuation of breastfeeding, appropriate transition to nutritious family food and psycho-social support for recovery. The term "Codex Alimentarius" is Latin and means "food code”. Codex standards are international food texts, i.e. standards, codes of practice, codes of hygienic practice, guidelines and other recommendations, established to protect the health of the consumers and to ensure fair practices in the food trade. The collection of food standards and related texts adopted by the Codex Alimentarius Commission is known as the Codex Alimentarius.
