Proteos

Proteos is a major international research programme, addressing the supply of protein for human diets. Proteos is funded by a consortium of commercial food organisations through the Global Dairy Platform (USA).  The overall aim of the programme is to assess protein quality for multiple foods. The results will be publicly available.

DIAAS

We are using a new methodology “Digestible Indispensable Amino Acid Score” (DIAAS) for evaluating the nutritional quality of protein sources.  DIAAS is endorsed by the FAO – Food and Agriculture Organization of the United Nations –  and is considered to be the best method currently available to evaluate protein quality.

There is not sufficient information on how much protein (and their building blocks, amino acids) in different foods is absorbed into the body and how it impacts on health.  Project Proteos was developed to aid formulation of appropriate diets around the world, particularly in developing countries. The project is being led by the Riddet Institute.

DIAAS involves determining how much of each amino acid from a food is available to the body when the food is eaten. The result is then compared to the requirements for the human body to aid design of diets.

Proteos Project News

The first stage of Proteos has been completed.  This was a collaboration between the Riddet Institute, Wageningen UR (Netherlands), the University of Illinois (USA) and AgroParisTech (France).  We developed, standardised and validated methods to determine the digestibility of amino acids when protein sources are consumed by humans. The methods were applied in different laboratories in different parts of the world and achieved consistent results.

We are now working with Wageningen UR (Netherlands) and the University of Illinois (USA) to examine the digestibility of numerous protein sources . An openly available global database of protein quality will be constructed, including 100 different protein sources.  These protein sources will be from a large range of different protein types, including protein sources commonly consumed in developing countries.
