In the latest update (BDA, 2022) we decided to present the composition of data not only per 100g of food/non-alcoholic beverage or 100 mL of alcoholic beverage, but also per serving.
The portions have been defined considering the Italian food tradition, the consumer’s expectations and the data present in the literature.
As data sources, we used the Standard Portions defined by the Italian Society of Human Nutrition (SINU) in the Dietary Reference Values of Nutrients and Energy for the Italian population (LARN, IV revision 2014), portion reported in photographic food atlases (Bedogni G., 2006; Turconi G., & Roggi C., 2007) or in Italian and foreign food composition tables and databases, while others have been defined by BDA working group.
In other cases, we used portions in natural or commercial units (e.g. slice, can, etc.), or in household units (e.g. table spoon, teaspoon, glass, etc.).
Furthermore, we decided to give the user the possibility to enter the desired portion manually.
