In Task 300 you can create a table of unique food codes that appear in your subject file. Candat will go through all of your selected subjects and store the unique codes found in a table of your choosing. Once done you can go to task 210, the food groups definition task and choose the food category of interest. By pressing slash (“/”) you will get a secondary menu which allows you to work with the categories. One of the options here is the “Validate group definitions” option. This will create a listing for you which will show, for all the foods in your unique foods table, the group in which they will fall. If there is no code beside a food it means it will fall outside the defined groups and appear as such in your nutrient reports by group feature (Task 340).
