Actions to promote the consumption of a sustainable diet

Improving food and nutrition educationThe structural and environmental changes described above must go hand in hand with nutrition education campaigns, awareness raising for behavioural change, knowledge transfer and consumer empowerment.29,30. Nations can influence consumer perceptions of the nutritional value and sustainability of food through media campaigns, information on food packaging, nutrition education in educational centres and the adoption of national guidelines on food, nutrition and nutrition education. One way of doing this is through widely-circulated food guides.31 Nutritional education alone is not enough, especially in food-insecure countries, and must be combined with strategies to improve access to nutritious food.32

Food-based dietary guidelinesFood-Based Dietary Guidelines (FBDG) are national tools whose purpose is to educate the population and guide national food and nutrition policies as well as the food industry, through easy-to-understand messages and illustrations. FBDGs are intended to inform national policymaking and provide the general public with advice on foods, food groups and dietary models that provide key nutrients with the aim of promoting overall health and preventing chronic diseases.33

It is also important to consider food culture when drafting FBDGs, as this knowledge can increase their effectiveness. Food culture comprises food uses, traditions, customs and symbolic processes, which are also influenced by the food production cycle in a particular context.34
