RESULTS Our findings suggest that consumers have a relatively poor underst and ing of a healthy diet .
The literature also demonstrates that there is poor evidence on the health protective effects of single foods or nutrients .
We further show that low SES is the single consistent risk factor for not adhering to a healthy diet .
Our review of the literature on determinants demonstrates that intentions , habits , self-regulatory skills , and the social and physical environment are the most important determinants of a healthy diet , which are in turn amenable to change by intervention strategies with varying levels of effectiveness .
Educational interventions generally show a limited effect on practising a healthy diet whereas interventions targeting habitual behaviour and /or the physical environment seem more promising .
In view of the large number of people who are concerned about their diets and make attempts to change their dietary patterns , we conclude that it is crucial to gain a better underst and ing of both the automatic and environmental influences that are responsible for people not acting upon their good intentions for diet change
OBJECTIVE To discuss healthy diet from a psychological perspective by considering definitions of healthy diet in terms of consumer underst and ing ; the health effects of specific dietary elements in terms of overweight and ( chronic ) illness ; the prevalence of healthy diet ; the psychological and environmental determinants of healthy diet ; and the psychological interventions that have been design ed to promote healthy diet .
Using aversive images to enhance healthy food choices and implicit attitudes: An experimental test of evaluative conditioning.
OBJECTIVE To examine the effect of communicating images of energy-dense snack foods paired with aversive images of the potential health consequences of unhealthy eating , on implicit and explicit attitudes and food choice behavior . DESIGN Participants were r and omly allocated to either an evaluative conditioning ( EC ) procedure that paired images of snack foods with images of potential adverse health consequences or a control condition that featured images of snack foods alone . MAIN OUTCOME MEASURES Implicit attitudes were assessed pre- and post-intervention . Explicit attitudes and food choice behavior were assessed post-intervention . RESULTS The conditioning intervention made implicit attitudes toward energy-dense snacks more negative , with this effect greatest in those with relatively more favorable implicit attitudes toward these snacks at baseline . Participants in the conditioning intervention were more likely to choose fruit rather than snacks in a behavioral choice task , a relationship mediated by changes in implicit attitudes . CONCLUSION Presenting aversive images of potential health consequences with those of specific foodstuffs can change implicit attitudes , which impacts on subsequent food choice behavior
