An interactive computerized dietary measurement system and process which can be used by lay people for accurate measurement of the intake of foods, nutrients, and other food components in the diet. The system includes a computer device coupled with an electronic balance, output/display device(s), user input element(s), a food codes database and a storage element. The system has the ability to provide a plurality of weigh-in measurement options with respect to different food service settings or habits and to respectively tag the measurement of each of the options selected by the user in the storage element so as to track the measurements. The system can instruct user on the next measurement action and required input so that users are not required to remember all of the measurement actions and sequences of the actions for the measurements. The system also provides a plurality of weigh-out measurement options in which the computer will track the measurement record and remind the user of what has been done and what should be done so that a complete and accurate collection of dietary intake data can be achieved. The system is further capable of signalling to the user any weighing errors for allowing user to correct the errors, and of permitting user to make comments or notes as to measurements.
