Rossato describes the development of a dietary data entry system for research that is user-friendly, multipurpose, and adaptable to different lists of food items, recipes, and serving portions for any region of the world, based on the Visual BAsic for Application (VBA) in Excel (version 2010, Microsoft). He states that DietSys may be a feasible software program for dietary data entry when suitable software is not available for a specific population and adds that using DietSys reduced the amount of time needed for data entry and can maintain data quality by preventing typographical errors and merging dietary with nondietary questionnaires in one data bank at the time of data entry.
