Abstract This research work is to develop an expert system for nutrition analysis for ailing humans. The software is an expert system with a database containing expert knowledge. An expert system or electronic diagnose system is a software-hardware system that attempts to reproduce the performance of one or more human experts, most commonly in a specific problem domain, and is a traditional application and/or subfield of artificial intelligence. The system runs on computer devices (laptop, desktop) and offers smart features that evaluate the nutritional condition of an individual by assessing their physical characteristics and eating habits. We explain the knowledge engineering process used to develop the system, overview the system architecture and selected design tools, and summarize some preliminary results from the implementation. This system was developed using V.B.NET and MS ACCESS for the database.
