Understanding this intention–behaviour gap is critical for policymakers and food businesses and working to accelerate dietary change. The findings highlight how affordability and routine interact to influence sustainable diets in Europe.
Based on nearly 20,000 consumers surveyed as part of the TrustTracker® study, this chapter provides one of the most comprehensive pictures of consumer attitudes to food in Europe today – examining diet satisfaction, nutrient intake, generational differences and approaches to sustainable food.
- Healthy eating: rising intentions, limited action
More than half of Europeans want to eat healthier, but habits and especially budget constraints are becoming stronger barriers. Although people believe they are eating slightly healthier, their answers show they are actually consuming fewer fruits, fibers, vegetables, and proteins.
- Generational differences in healthy eating
Younger adults are more focused on protein intake, influenced by fitness culture and the belief that more protein is always beneficial. Older adults report more consistent eating habits, cook more at home, and say they consume enough fruits and vegetables.
- Sustainability: declining intention, low real‑world participation
The intent to live sustainably has been decreasing steadily since 2021, and this decline is reflected in weak real-life behavioral changes. Only small groups actively avoid animal products or buy organic, even though slightly more people say sustainability influences their food choices. [
- Generational differences in sustainability behavior
Younger consumers show more interest in food origins, sustainability labels, organic choices, and even growing their own food. Older consumers focus mainly on reducing food waste and cooking meals at home.
- The intention–behavior gap
There is a widening gap between what people want to eat and what they actually consume, driven by habits, price, and convenience. Health is the strongest motivator for behavioral change and is more effective at promoting plant-forward diets than sustainability messaging.
