    Research approaches and methods for evaluating the protein quality of human foods
    Report of a FAO Expert Working Group, 2 – 5 March 2014, Bangalore, India

    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.

    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

    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.

    Russian Federation: Meat sector review
    Country highlights prepared under the FAO/EBRD Cooperation
    2014
    Also available in:

    World food demand has seen massive changes, including a shift from staple foods to animal proteins and vegetable oils. In the short to medium term, this trend in global food demand will continue. There will be an increased demand for vegetable oils, meat, sugar, dairy products and livestock feed made from coarse grains and oilseed meals. There are numerous mid-term forecasts for the Russian Federation’s meat sector. Most of them agree on the following trends: (i) the consumption of poultry and p ork meat will increase; (ii) the consumption of beef will decrease or stabilize; and (iii) the Russian Federation will remain a net importer of meat on the world market. According to OECD and FAO projections, meat imports from the Russian Federation will decrease from 3 to 1.3 million tonnes, owing to an anticipated growth in domestic chicken meat and pork production. The country’s share in global meat imports is anticipated to decrease from 12 percent in 2006–2010, to 4 percent in 2021. While t he Russian Federation will continue to play an important role in the international meat market, it will fall from its position as the largest meat importing country in 2006–2010 to the fourth largest global meat importer by 2021, behind Japan, sub-Saharan African countries, and Saudi Arabia.

    The State of Food Security and Nutrition in the World 2021
    Transforming food systems for food security, improved nutrition and affordable healthy diets for all
    2021
    In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.
