The first National Food Consumption Survey in Belgium was conducted in 2004 among 3,200 adults aged 15 and above. Nationally representative data on the Belgian population were collected in 2014-2015 for people between 3 and 64 years old. The next data collection wave is planned for 2022 and will collect food consumption data from 3,020 participants aged 3 and above.

Participants provide detailed information about their diets spread over two non-consecutive days via a 24-hour dietary recall. In 2022, 1,400 additional participants will be surveyed in Brussels and in the German-speaking Community using the Food Frequency Questionnaire method. In addition, all participants provide information on topics such as 

• their eating habits, 
• their opinions on the food policy, 
• their physical activity
• their sedentary behaviour. 

Weight, height, and waist circumference are also measured objectively. In children and adolescents, physical activity and sedentary behaviour were measured objectively using an accelerometer in 2014-2015. A detailed description of the methodology and the results are available on the website of the 2014-2015 Belgian Food Consumption Survey. Nutrition and eating habits as well as food policies change constantly, which is why food consumption surveys need to be organised regularly.
