This study focuses on the connection between prosocial behavior, defined as acting in ways that benefit others, and shared meals, defined as meals that consist of food(s) shared with others. In contrast to individual meals, where consumers eat their own food and perhaps take a sample of someone else's dish as a taste, shared meals are essentially about sharing all the food with all individuals. Consequently,...
The hypothesis that human self-control capacities are fueled by glucose has been challenged on multiple grounds. A recent study by Lange and Eggert adds to this criticism by presenting two powerful but unsuccessful attempts to replicate the effect of sugar drinks on ego depletion. The dual-task paradigms employed in these experiments have been criticized for involving identical self-control tasks,...
Background: National data suggest a higher prevalence of obesity among boys. One possible cause could be the food choices made by parents on behalf of their children. Objectives: This study sought to determine whether and how mothers' food choices for their children differ by child gender and to understand the drivers of these differences. Design: Data were analyzed from a randomized controlled trial...
Picky eaters are defined as those who consume an inadequate variety of food through rejection of a substantial amount of food stuffs that are both familiar and unfamiliar. Picky eating is a relatively recent theoretical concept and while there is increasing concern within public health over the lack of diversity in some children's diets, adult picky eaters remain an under researched group. This paper...
Food variety increases consumption and the rate of instrumental behavior that is reinforced by food in humans and animals. The present experiment investigated the relationship between the variety effect and habituation to food by testing the role of the interval between successive food presentations on responding in an operant food-seeking task. Habituation to food was expected at short, but not long,...
Background: Those of lower socioeconomic status (SES) tend to have less healthy diets than those of higher SES. This study aimed to assess whether differences in motivations for particular foods might contribute to socioeconomic differences in consumption. Methods: Participants (n = 732) rated their frequency of consumption and explicit liking of fruit, cake and cheese. They reported eating motivations...
The objective of this study was to evaluate an intervention that combined mindful eating and online pre-ordering to promote healthier lunch purchases at work. The study took place at an urban hospital with 26 employees who were overweight or obese. The design included a contemporaneous comparison with delayed-treatment control and a three-phase prospective study. A minimum 4-week baseline period preceded...
In a random sample (N = 951) from the general population, direct and indirect effects of the Big Five personality traits on eating styles and food choices were examined. Path models revealed that high openness to experience were associated with higher fruit, vegetable and salad and lower meat and soft drink consumption. High agreeableness was associated with low meat consumption. Neuroticism, conscientiousness...
The purpose of the present article is to highlight limitations of Lange and Eggert's methodology of using identical self-control tasks in testing effects of glucose on depletion of self-control resources and self-control performance. We suggest that when participants engage in two identical self-control tasks, cognitions developed during initial act of self-control may mask the effects of glucose...
As criticisms of factory farming continue to mount, an increasing number of individuals have changed their existing dietary practices. Perhaps the two most important food movements reacting against industrial farming are (1) vegetarianism, the avoidance of animal flesh; and (2) conscientious omnivorism (CO), the consumption of meat or fish only when it satisfies certain ethical standards. While the...
Background: Picky or fussy eating is common in early childhood and associated with a decreased preference for a variety of foods. The aim of the current study was to test experimentally which sensory food feature influences food acceptance, which, in turn is an indication for fussy eating, in young children (32 - 48 months). Another aim was to evaluate if the behavioural measurement of food acceptance...
Understanding the contribution of caregiver feeding practices to adolescent diet and weight is important to refining caregiver roles within the context of adolescent obesity prevention and treatment. This secondary data analysis examined whether feeding practices of female caregivers differentiated persistently non-overweight (n = 29) from persistently obese (n = 47) adolescents. Families who previously...
Snacking has become more frequent among US preschool-aged children in recent decades and represents a significant proportion of daily energy intake. Social influences on snacking among children, however, are not well understood. This qualitative research described low-income, urban mothers' perceptions of feeding snacks to their preschool-aged children using data from 7 focus groups with 32 participants...
Behavioural and cognitive pathways that lead to the activation and escalation of craving have been studied extensively. Conversely, limited efforts have been directed towards understanding how craving relates to motivational systems and neuroendocrine responses. These can be understood using the biopsychosocial model of challenge and threat. In the current study, forty participants with varying levels...
From both a clinical and research perspective, measuring food intake is an important issue in geriatric institutions. However, weighing food in this context can be complex, particularly when the items remaining on a plate (side dish, meat or fish and sauce) need to be weighed separately following consumption. A method based on photography that involves taking photographs after a meal to determine...
Despite a common perception that fruit juice is healthy, fruit juice contains high amounts of naturally occurring sugar without the fibre content of the whole fruit. Frequent fruit juice consumption may therefore contribute to excessive sugar consumption typical of the Western society. Although excess sugar intake is associated with high blood pressure (BP), the association between habitual fruit...
Learning may play an important role in over-eating. One example is Pavlovian-to-instrumental transfer (PIT), whereby reward cues facilitate responding to obtain that reward. Whilst there is increasing research indicating PIT for food in humans, these studies have exclusively tested PIT under instrumental extinction (i.e. when the food is no longer available), which may reduce their ecological validity...
Young children commonly encounter difficulties at mealtimes, which are important to address early to avoid the maintenance of problematic eating behaviour. Amongst these are drawn-out meals, which some research has associated with more mealtime problems. However, research on meal duration, and therefore guidelines for appropriate meal length, is lacking. This research aimed to compare the meal duration...
Background: Front-of-pack (FOP) nutrition rating systems and symbols are a form of nutrition marketing used on food labels worldwide. In the absence of standardized criteria for their use, it is unclear if FOP symbols are being used to promote products more nutritious than products without symbols. Objectives: To compare the amount of calories, saturated fat, sodium, and sugar in products with FOP...
