Healthy is (not) tasty? Implicit and explicit associations between food healthiness and tastiness in primary school-aged children and parents with a lower socioeconomic position

Food for thought: The impact of short term fasting on cognitive ability

Growing evidence suggests that resource scarcity can severely impede individuals' cognitive capacity, resulting in sub-optimal decision making. Few experimental studies investigate whether food deprivation as a form of resource scarcity influences decisions in other non-hunger related domains. We examine the effect of short term fasting on cognitive capacity by exogenously manipulating individuals' fasting time in a laboratory experiment. Participants were randomly assigned to one of three treatments: 1) 3-hour fast; 2) 12-hour fast; and 3) control, in which participants were not required to fast and consumed a protein shake upon arriving to the lab. Following the manipulation, participants completed the Raven's Progressive Matrices test which measures cognitive function. Although we find null treatment effects on cognitive ability, our results provide evidence that short term fasting does not directly inhibit cognition.

Repeated exposure to models' positive facial expressions whilst eating a raw vegetable increases children's consumption of the modelled vegetable

Exposing children to adults eating a raw vegetable with positive facial expressions ('positive modelling') increases children's consumption of the modelled vegetable. However, whether repeated versus a single exposure to positive modelling enhances this effect, and whether it generalises to a non-modelled vegetable, remains to be examined. Hence, this study examined the effect of a single exposure, versus repeated, exposure to positive modelling on children's acceptance and intake of a modelled and non-modelled vegetable. Children aged 5-6 years (N = 153; 81 males, 72 females) were randomised to one of three conditions in which they had i) a single or ii) repeated exposure to a video of adults eating raw broccoli with positive facial expressions or iii) were exposed to a no-food control video. Children's acceptance (measured as willingness to try and number of tastes), intake and liking of a modelled (raw broccoli) and non-modelled vegetable (raw mangetout) were measured. Children had greater raw broccoli consumption and liking if they had received repeated exposure to positive modelling, compared to children who had received a single exposure, but not compared to children in the control condition. Children's mangetout intake was greater in the single (versus repeated) positive condition, but this effect was not dependent on time. There was no effect on children's vegetable acceptance. Repeatedly exposing children to adults enjoying a vegetable encourages children's intake of the modelled vegetable in comparison to a single exposure. Thus, repeated exposure to others' food enjoyment may be a practical and useful strategy to encourage children's vegetable consumption.

The visual analogue scale as a child-friendly measure of the unhealthy = tasty intuition

Worldwide, obesity is a growing concern. The implicit belief that healthiness and tastiness in food are inversely related (the Unhealthy = Tasty Intuition or UTI) decreases healthy food consumption and increases the risk of obesity. Since also childhood obesity has increased at an alarming rate and a large component of adult obesity is established during childhood, questions about children's own food beliefs and preferences are important. However, methods currently used to assess the UTI are either unvalidated Likert scales or implicit measures that are time intensive and too complex to be used for children. Two studies presented here offer an alternative measurement - the simple visual analogue scale. The findings show that this measure is more effective in predicting dietary quality in adults and the frequency of healthy food consumption in children compared to more traditional measures. This simple and effective tool could be used by academics and health practitioners alike to better understand children's food beliefs at an early age, which is a critical step when addressing the increasing obesity problem.

"Unhealthy = Tasty": How Does It Affect Consumers' (Un)Healthy Food Expectations?

Consumers having a strong unhealthy = tasty (UT) belief are less likely to choose healthy food even though they recognize its health benefits, because they assume healthy food to be unpalatable. The aim of this study was to profile consumers according to their UT belief and specify the strength of the belief among a demographically representative consumer group. The other aim was to investigate the effect of UT belief on expectations of two food products representing either an unhealthy or a healthy image. A total of 1537 consumers participated in the online survey. The scale-based (1-7) mean for UT belief was 3.27 and related positively to male gender and food pleasure orientation and negatively to general health interest. The results indicate that a strong UT belief correlates with positive expectations of unhealthy food and with negative expectations of healthy food. UT belief seemed to increase expected food-associated guilt, but other strong food-related attitudes (health interest with unhealthy food and pleasure orientation with healthy food) reduced this effect. In practice, understanding the relationship between UT belief and personal factors and attitudes, and the importance of this belief to food expectations can assist in finding the tools to encourage consumers towards healthier food choices.

To like or not to like: Negotiating food assessments of children from families with a low socioeconomic position

The present study explored how primary school-aged children from families with a low socioeconomic position produce 'likes' and 'dislikes' of foods during everyday family meals, and how these (dis)likes are understood and treated by their parents. It is crucial to understand how food preferences develop in the course of everyday life, as it is known that there are socioeconomic disparities in food preference and consumption, and that children from families with a low socioeconomic position have relatively poorer diets. Deploying an interactional approach to food preference, video recordings of 79 evening meals in families with a low socioeconomic position were analyzed using discursive psychology and conversation analysis. The analysis highlighted that children's food likes and dislikes were treated differently by their parents. While likes were routinely not responded to, agreed with or further elaborated, dislikes were predominantly oriented to as food refusals or treated as inappropriate, or non-genuine claims. Children's food assessments, i.e., likes and dislikes, were often disattended by parents when they appeared to be food preference displays. By contrast, assessments that accomplished social actions like refusals and complaints were more often responded to. The analysis also revealed the importance of distinguishing between assessments about food items in general, that were not currently being eaten, and assessments of food eaten here-and-now. All in all, the study evidences that and how assessment sequences open up interactional spaces where children and parents orient to and negotiate relative rights and responsibilities to know, to assess and to accomplish specific actions. Implications for food preference research are discussed.
