In the context of the assessment of nutritional intake, it is important to improve and extend traditional food report methods by taking the development of new technologies and the changing lifestyle of the population into account. Therefore the Intake24 system, as a web-based 24-hour recall tool with integrated food photographs as an estimation aid, was developed. The aim of the presented studies was to evaluate the accuracy and precision of estimates made by participants using Intake24 and gain a greater insight into the needs of the users. A controlled feeding study was conducted, in which 40 participants attend four meals and were requested to enter their intake into the system on the next day. Concerning the accuracy of estimations, the results indicate a mean underestimation of 11%, so Intake24 is a promising tool and may provide an adequate substitute for 24-hour recall interviews with some modification.
