DIAASarvoissa

DIAASarvoissa is a concept related to the assessment of food protein quality. It stands for Digestible Indispensable Amino Acid Score. This scoring method aims to provide a more accurate reflection of the protein's nutritional value by considering both the amino acid profile and the digestibility of those amino acids in the human body.

Unlike traditional methods that solely focus on the amino acid composition, DIAASarvoissa takes into account how well the body can actually absorb and utilize the essential amino acids present in a food protein. This is particularly important because some proteins, even if they contain all the necessary amino acids, may not be fully digestible, leading to a lower effective contribution of those amino acids to the body's needs.

The DIAAS score is calculated by comparing the amounts of indispensable amino acids in a specific food protein, per gram of protein, to the amounts required by a reference population. This comparison is then adjusted for the true digestibility of each indispensable amino acid. A higher DIAAS score generally indicates a higher quality protein. This method has been proposed by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) as a more reliable indicator of protein quality for human nutrition.
