S/PS/24. An attempt to change health behaviour by eating five portions of fruit and vegetables daily: A critical evaluation

Changing aspects of one's health behaviours is an increasingly common occurrence in today's health-conscious world. Public health authorities often lead campaigns specifically aimed at encouraging individuals to review their current health status and attempt to improve it either by adopting new or changing current health behaviours. These range from smoking cessation, to increased exercise or change in diet. There are, however, certain processes and stages than one has to go through before they engage in behaviour. A number of theories and models have therefore been developed, in order to examine the factors behind adopting health behaviour and the failure or success of the individual to maintain it.
