Priming healthy eating. You can't prime all the people all of the time.
Bottom Line: In Study 1, hunger reduced preferences for fruits (OR (95% CI) = 0.38 (0.26-0.56), p <0.0001), an effect countered by the prime (OR (95% CI) = 2.29 (1.33-3.96), p = 0.003).In Study 2, the effect of the prime did not generalize to a representative population.This study provides preliminary evidence that the effects of adverts on healthy eating choices depend on key individual traits (education level) and states (hunger), do not generalize to a broader population and have the potential to increase health inequalities arising from food choice.

Mentions: However, consistent with Hypothesis 1, there was a significant interaction between hunger and prime on the number of fruits chosen in the food preference task. There was an overall effect of hunger, in that hunger reduced the odds of fruits being chosen (OR (95% CI) = 0.38 (0.25–0.56), p < 0.0001). Within the group of participants reporting some hunger, those in the prime condition were more likely to select fruits than those in the non-prime condition (OR (95% CI) = 2.29 (1.33–3.96), p = 0.003). The prime had no effect on participants who reported no hunger (OR (95% CI) = 1.11 (0.60–2.04), p = 0.736) (Table 2, Fig. 1).
