About this trial
A new dietary assessment method was developed based on the Experience Sampling Methodology. In order to use this newly developed Experience Sampling Dietary Assessment Method (ESDAM) in research and clinical practice as a valid and reliable method to measure dietary intake the ESDAM needs to be validated against objective biomarkers and reference methods.
