In the perception study, agreement between the portions shown and reported was substantial (intraclass correlation coefficient (ICC)=0·805) and the mean difference was very low. In the memory study, agreement between the served and reported portions was lower than in the perception study (ICC=0·536). Agreement also seemed to decrease as the appearance of food on the plate differed from food in the picture.</jats:p> </jats:sec> <jats:sec id="S1368980017004153_abs6" sec-type="conclusions"> <jats:title>Conclusions</jats:title> <jats:p>Overall, the picture series selected can be applied in future intake surveys to quantify foods similar to those depicted in the pictures.</jats:p> </jats:sec>
