It is often difficult to distinguish compiled from analytical data in food composition tables, and to collect, if needed, analytical data from different sources. To overcome this problem, FAO/INFOODS decided to publish the FAO/INFOODS Analytical Food Composition Database (AnFooD) in order to assist countries to obtain high quality food composition data for their work. The document includes information on how to read, use and interpret the data including definitions, codes etc. and also updates m ade to the current version.
