Candat has a sophisticated food group analysis function. Food groups are lists of foods which belong to a specific group. These lists are defined as individual food codes or ranges of food codes. Definitions of multiple food groups taken together are stored in what Candat calls a “Category” file. It is thus possible to have category files for many different kinds of food groupings. For instance you could have a category file for groupings of interest to diabetic subjects or particular kinds of cancer subjects or heart disease subjects. There is no limit to the kinds of category files that you can define and, once defined, can use in all your studies.
