This methodology report describes the procedures used to analyse food consumption and adherence
to food-based dietary guideline in the Brussels-Capital Region and the German-speaking Community,
based on data from the 2022-2023 Food Consumption Survey.

Food consumption in the additional sample of Brussels and the German-speaking Community was
assessed using a Food Frequency Questionnaire (FFQ), completed once by each participant (see

2.2.2.3.). The report outlines the steps taken to prepare the food consumption database, including the
coding of reported frequencies and portion sizes, data cleaning procedures, and the identification of
extreme values.

evaluate adherence to food-based dietary guidelines.
