Guidelines for selecting a dietary analysis system

Microcomputers provide an effective and efficient method for dietary data management and analysis. Since the selection of an appropriate software system is a confusing task, prospective users must have a clear statement of needs. Selection of software is simplified when specific data management tasks are defined. This article provides a model for listing dietary analysis needs and priorities. Sample dietary analysis tasks are listed for five areas of responsibility. Prospective users should consider the following characteristics for each system: validity of the data base, soundness of the program's internal operating procedures, clear and complete documentation, an easy-to-read computer output, and credibility of the developer. Characteristics that may vary in importance depending on the user's situation include ability to alter the data base, standard operating procedures, output features, and service policies. By looking carefully at needs and matching needs to available systems, dietitians can apply sophisticated dietary data management and analysis techniques to the nutrition needs of their clients.
