The present research is within the field of social and health psychology studies and focused on explaining and promoting healthy eating behaviours within the Theory of Planned Behaviour (TPB; Ajzen, 1991). Two studies investigated if the TPB, plus self-identity and controlling for past behaviour, could explain fruit and vegetable intake (Study 1: N = 210; mean age = 22.91; SD = 8.33 ) and red meat consumption (Study 2: N = 405; mean age = 19.58; SD = 2.03). Results found support for the validity of TPB for explaining these behaviours and showed the additional predictive role of self-identity, even when controlling for past behaviour. Furthermore, two randomized controlled trials evaluated the effectiveness of SMS interventions for increasing fruit and vegetable intake (Study3: N = 1059; mean age: 15.41; SD = 1.53) and for reducing red meat consumption (Study 4: N = 244; mean age: 19.42; SD: 1.44). Findings showed that daily persuasive messages were an effective strategy for increasing fruit and vegetable intake and reducing red meat consumption in young people.
