Are eco-sustainable dietary patterns associated with impulsiveness? An insight from Italy.

ABSTRACT

Impulsivity is known to influence food choices. We explored possible differences in its expression between individuals with or without an eco-sustainable diet and its relationship with cognitions and behaviours about eco-sustainable foods. Participants were categorised as having or not having an eco-sustainable diet. Impulsivity traits and cognitions and behaviours about sustainable food products were measured. Among the 332 participants, 92.78% showed an eco-sustainable diet, whereas only 7.22% had an eco-sustainable diet. No difference between groups emerged about impulsive traits, whereas significant differences emerged in cognitions and behaviours about sustainable foods, with the only exceptions of subjective norms and past behaviour. Impulsive traits were linked to cognitions and behaviours differently within groups. Impulsivity traits may be related to actions towards eco-sustainable foods, with the perception of their availability playing a crucial role. Increasing contextual opportunities may be fundamental for having eco-sustainable consumers.
