The underlying food composition data used for the Xyris food group system is AUSNUT 2011-13 and the Australian Food Composition Database (2019), which are the official food composition tables from Food Standards Australia New Zealand (FSANZ).
Xyris has developed a food description database of generic foods, AusFoods, that is a user-friendly wrapper for AUSNUT 2011-13 and AFCD. AusFoods provides a set of food names that is more complete and structured than the ‘raw’ AUSNUT and AFCD foods. Each AusFood food derives its data from AUSNUT 2011-13/AFCD.
Xyris has also developed a database of Australian commercial food products, AusBrands. Each of these commercial products is mapped to an AusFoods generic food (and thus back to AUSNUT 2011-13/AFCD), allowing full nutrient analyses (beyond the nutrients on the label) including food group analyses, for the AusBrands foods.
