Adults who both reflected on personal values before reading information about the benefits of eating fruits and vegetables and who made a plan about how to do so using an “If…then…” template reported eating more fruit and vegetables 7 days later; there was no benefit for either intervention on its own. At a 3-month follow-up, both the affirmation intervention and the implementation-intention intervention produced independent (non-interacting) increases in reported fruit and vegetable consumption, though the later was marginally significant.
