Introduction
There are various ways to reduce the workload and effort involved in nutrition logging: existing Food Frequency Questionnaires (FFQs) can be shortened or adapted for use in web-based formats and innovative (e.g., image-based) logging methods can also be developed and used [1–4]. Devices with a digital camera are now ubiquitous, so these devices are the most commonly used tools for recording food intake when using an image-based nutrition record. Before eating, the person takes photos of the food and/or drink they are about to eat/drink [4, 5]. The photos can be used to identify the type of food the person has eaten and, if necessary, the portion sizes [4].
Study question
An abridged FFQ (Short FFQ, SFFQ) was compared with the corresponding long-form (LFFQ) of an online FFQ that had already been developed and validated [6]. Additionally, an image-based nutrition record (ibNR) was developed and its suitability for use in analysis was tested. The ibNR was used to determine whether and how the FFQs could be updated. ...
