ABSTRACT
Sustainability is crucial for transforming the food system, addressing environmental and nutrition issues and depends on consumer perceptions and values. This cross-sectional study investigates the relationship between sustainability attitudes, knowledge, and eating behaviours. Nearly half reported high level of knowledge regarding food sustainability while 24% expressed high attitude towards food sustainability. Women reported higher levels of knowledge and attitude towards food sustainability. Logistic regression analyses, adjusted for age, sex, and education, revealed that using public transport, biking, or walking was significantly associated with higher odds of having a more positive overall attitude towards food sustainability (OR = 1.77). The overall knowledge score was a strong predictor of a positive overall attitude score (OR = 2.11). Examining individual knowledge-related items, almost all were associated with higher levels of knowledge, except those regarding food and environment interaction. These findings underline a complex scenario where consumers' awareness and knowledge highly influence the applicability of sustainable food choices.
