Abstract: The invention establishes a set of nutritional profiles in a data processing system, which are utilized to establish an optimal meal menu for a given time and location and with regard to a set of available ingredients. The invention includes a profiling routine where a set of characteristics of a particular individual is entered. The characteristics are aggregated with data saved for other patrons. When an individual with an established profile enters a networked eatery, they initiate a menu routine by entering their identification. The routine matches the information with the aggregated data to determine a patron match, which in turn is matched with the set of characteristics to determine an optimal menu plan. The optimal menu plan is matched with the set of available ingredients to produce a menu. Selected menu items are recorded to the patron's nutritional profile which can be visually represented in any of several formats.
