How Mood Influences Food Choice
Gardner, M., Wansink, B., Kim, J., Park, S. (2014). Better Moods for Better Eating?: How Mood Influences Food Choice. Journal of Consumer Psychology. Forthcoming.
To get at the “why,” we married the theories of affective regulation (how people react to their moods and emotions) and temporal construal (the perspective of time) to explain food choice. Conceptually, when people feel uncomfortable or are in a bad mood, they know something is wrong and focus on what is close in the here and now. We hypothesized and demonstrated that this kind of thinking gets us to focus on the sensory qualities of our foods – not things that are more abstract like how nutritious the food is. Analogously, we hypothesized and demonstrated that when people are in a good mood, things seem okay and they can take a big picture perspective. This kind of thinking allows people to focus on the more abstract aspects of food, including how healthy it is.
We studied these hypotheses in four laboratory experiments. In the first study, we investigated the effect of a positive mood on evaluations of indulgent and health foods by examining 211 individuals from local parent-teacher associations (PTAs). Next we studied whether individuals in a negative mood – who had read a sad story-- evaluated indulgent foods more positively and whether those who were in a positive mood indicated a desire to remain healthy into their old age. 315 undergraduate students participated in this study. In the third study, involving 151 undergraduate students, we altered participants’ focus on the present versus the future along with their mood and measured how much healthy and indulgent food they consumed. To get more direct insight into the underlying process, the fourth study, involving 110 university students, focused specifically on the thoughts related to food choice and differentiated concrete taste versus nutrition benefits.
Ultimately, the findings of all the studies combined demonstrated that individuals select healthy or indulgent foods depending on whether they are in a good or a bad mood, respectively. The findings also indicate the integral aspect of the time horizon, showing that individuals in positive moods who make healthier food choices are often thinking more about future health benefits than those in negative moods, who focus more on the immediate taste and sensory experience. Finally we found that individuals in negative moods will still make food choices influenced by temporal construal which suggests that trying to focus on something other than the present can reduce the consumption of indulgent foods.
