Synopsis (short abstract) 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.

    Protein quality assessment in follow-up formula for young children and ready to use therapeutic foods
    Report of the FAO Expert Working Group, Rome, 6–9 November 2017

    Consistent with the need to provide safe food for young children, particularly during the complementary feeding period between 12 and 36 months and the period of rapid development to age 59 months, the Food and Agriculture Organization of the United Nations (FAO) convened an Expert Working Group the FAO Headquarters, Rome, Italy, from 6 to 9 November 2017. The meeting addressed questions related to protein quality evaluation in two distinct products used to feed children in different conditions: Ready to Use Therapeutic Food (RUTF) and Follow up Formula for Young Children (FUF-YC). Specific meeting objectives were: • To determine the appropriate comparative protein or amino acid reference pattern to define protein quality for use in FUF-YC and RUTF. • To provide guidance on the preferred protein quality assessment methodology that should be stipulated with the standards for FUF-YC and RUTF. • To provide guidance on the measurement of protein and amino acid digestibility. • To provide the appropriate reference amino acid profiles and the amino acid composition of common ingredients used for FUF-YC and RUTF. • To provide cost implications for countries to use PDCAAS in FUF-YC and RUTF. This report provides future research recommendations including the need to generate data on the true ileal digestibility for different protein sources so that Digestible Indispensable Amino Acid Score (DIAAS) values can be used in the future.

    Protein is supplied by food ingredients, whole foods, sole-source foods and mixed diets and the match between dietary supply and human protein needs is vital to support the health and well-being of human populations. Since 1989 the Protein Digestibility Corrected Amino Acid Score (PDCAAS) method for evaluating protein quality has been used widely. However, limitations of PDCAAS have been recognised and new research and its application vis-à-vis other methods of estimating dietary protein quali ty. This report of the FAO Expert Consultation on Protein Quality Evaluation in Human Nutrition considers the effectiveness and concerns about the PDCAAS method for evaluating protein quality concerning the PDCAAS method. A new method of dietary quality evaluation called DIAAS is recommended for application in practice.

    Fats and fatty acid in human nutrition
    Report of an expert consultation, 10 − 14 November 2008 Geneva
    2010
    Also available in:
    The Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO), in their roles as technical agencies of the United Nations (UN), are charged with providing science-based guidance on food and nutrition to national governments and the international community. The process used to do this involves periodic and systematic reviews of scientific evidence, which often culminates with the convening of joint expert consultations to review the state of s cientific knowledge, deliberate on the issues and translate this knowledge into a definition of requirements and corresponding nutrient-based recommendations. The overall goal of these recommendations is to support health and nutritional well-being of individuals and populations. The topics covered during the recent past include energy, protein and amino acids, fats and oils, most of the vitamins and minerals and carbohydrates, with the objective of providing guidance on nutritional requirements and recommended dietary intakes.The Joint FAO/WHO Expert Consultation on Fats and Fatty Acids in Human Nutrition (hereafter Expert Consultation) was the most recent expert meeting convened, and was held in Geneva from 10 to 14 November 2008. The Expert Consultation was the third to be held on the subject of fats in human nutrition, the first expert consultation on this topic being held in 1977 (FAO, 1978) and the second in 1993 (FAO, 1994).
