Feeling well surrounded: Perceived societal support fosters healthy eating.

Societal resources (e.g. recreational facilities, free online information, healthy food retail) are consistently found to be important facilitators for healthy eating. In the current research, we propose that healthy eating is not only facilitated by the actual available support in society, but equally well by individuals' subjective perception on how helpful the provided support truly is. We refer to the latter as "perceived societal support" and examine how this influences healthy eating. Across two experimental studies, we observe that perceived societal support positively affects healthy eating: People who perceive the available support as helpful are more likely to choose healthy food over unhealthy food (study 1) and consume less from an unhealthy food product (study 2) compared to people who perceive the available support as less helpful. These findings do not only contribute to existing literature on societal support and healthy eating behavior, but also provide important policy implications.

Effects of mindset on hormonal responding, neural representations, subjective experience and intake.

A person can alternate between food-related mindsets, which in turn may depend on one's emotional state or situation. Being in a certain mindset can influence food-related thoughts, but interestingly it might also affect eating-related physiological responses. The current study investigates the influence of an induced 'loss of control' mindset as compared to an 'in control' mindset on hormonal, neural and behavioural responses to chocolate stimuli. Mindsets were induced by having female chocolate lovers view a short movie during two sessions in a within-subjects design. Neural responses to visual chocolate stimuli were measured using an ultra-high field (7T) scanner. Momentary ghrelin and glucagon-like peptide 1 (GLP-1) levels were determined on five moments and were simultaneously assessed with self-reports on perceptions of chocolate craving, hunger and feelings of control. Furthermore, chocolate intake was measured using a bogus chocolate taste test. It was hypothesized that the loss of control mindset would lead to hormonal, neural and behavioural responses that prepare for ongoing food intake, even after eating, while the control mindset would lead to responses reflecting satiety. Results show that neural activity in the mesocorticolimbic system was stronger for chocolate stimuli than for neutral stimuli and that ghrelin and GLP-1 levels responded to food intake, irrespective of mindset. Self-reported craving and actual chocolate intake were affected by mindset, in that cravings and intake were higher with a loss of control mindset than with a control mindset. Interestingly, these findings suggest that physiology on the one hand (hormonal and neural responses) and behavior and subjective experience (food intake and craving) on the other hand are not in sync, are not equally affected by mindset.

Attract the best: The attraction effect as an effective strategy to enhance healthy choices.

Every day, people make many food decisions without thinking, repeatedly falling for the unhealthy option instead of the healthy option. While making these mindless decisions, people often rely on heuristics. In this paper, we demonstrate that these heuristics can be exploited to nudge consumers towards healthy alternatives. Specifically, we explore how the attraction effect (i.e., adding a decoy to a choice set) can nudge people to choose a healthy snack. The results of our choice experiment indicate that adding a decoy (i.e., a less attractive food alternative) to a self-control situation (i.e., choosing between a healthy and an unhealthy food alternative) can help people maintain self-control and choose the healthy option. This mixed choice set thus nudges people towards the healthy option. Moreover, our results show differential effects of the attraction effect depending on the (un)healthiness of the products in the choice set. Specifically, the attraction effect is prominent when the choice set consists of unhealthy products only (i.e., the unhealthy choice set), but not in the choice set that consists of only healthy products (i.e., healthy choice set). Importantly, our results indicate when the attraction effect can exploit consumers' heuristics to help them make better, healthier food choices.

Exposure makes the heart grow less fond!: the effects of exposure to palatable foods on the subsequent attention processing of food cues.

Prior research has provided conflicting evidence on the question of whether exposure to food temptations directs attention towards or away from food cues. In this study, the effects of exposure to food temptations on attention processing were investigated using an exogenous cueing paradigm. The results show that exposure to food temptations led participants to direct their attention away from food cues. This effect was found after exposure to pictures of food as well as real food temptations. These findings suggest that food temptations activate a tendency to avoid food stimuli, regardless of the restraint and disinhibition levels of the participants.
