BACKGROUND: Orthorexia nervosa (ON) is characterized by obsessions about eating healthily and rigid adherence to a perceived healthy diet. This study uses the Eating Habits Questionnaire to investigate the relationship of ON symptoms with self-reported food intake, eating-related impairment, obsessive compulsive disorder symptoms (OCD), gender, and BMI while controlling for other eating disordered symptoms. The aim of this study is to provide further evidence for the construct of ON as distinct from other forms of disordered eating...

Home-packed lunches have been found to be of lower nutritional quality than school-bought lunches, yet little is known about family-based factors associated with lunch packing. The current exploratory study examines parental and family predictors of fruits and vegetables packed in lunches, hypothesizing parents' nutrition knowledge and authoritative parenting as well as children's involvement in lunch decisions would relate to packing more fruits and vegetables, while financial difficulties would relate to packing fewer...

This study aims to investigate consumers' green food purchase intentions using a survey conducted in Qingdao, Shandong Province, China. Based on the Theory of Planned Behavior (TPB), it models the influences of Chinese culture and consumer characteristics towards purchasing green food products. According to TPB, the behavioral intention is determined by attitude, subjective norms and perceived behavioral control, whereas subjective norms vary according to differences in cultural systems. This study incorporates traditional Chinese cultural constructs of face consciousness and group conformity instead of subjective norms to develop an amended TPB model under China's cultural environment...

Recent theoretical models and empirical research have indicated that momentary negative affect increases the likelihood of binge eating episodes for individuals with bulimia nervosa and binge eating disorder. However, relatively little research has explored the potential for positive mood to serve a protective effect in reducing the likelihood of overeating behaviour in bulimia nervosa and binge eating disorder. The current study included 30 women with bulimia nervosa or binge eating disorder in a within-subjects crossover design...

A virtual shopping task was employed to illuminate why women who intend to shop healthily are differentially successful in doing so. Female undergraduates (N = 68) performed a modified approach and avoidance task that employed food items differing in healthiness and tastiness, and yielded relative speed to select and reject food items in a stylised supermarket. Participants categorised a food item either in terms of healthiness or tastiness, then pulled (selected) or pushed (rejected) the item using a joystick...

BACKGROUND: This study examined whether seeing food-related TV content affected the accessibility of a hedonic eating goal differently for people scoring relatively high or low on eating restraint (i.e., chronic dieting) and perceived self-regulatory success (i.e., PSRS). METHODS: Three between-subjects experiments were conducted in which participants were exposed to food-related or non-food related TV content. In Experiment 1 (student sample, N = 111) and Experiment 2 (community sample, N = 69) participants watched TV commercials for food or non-food products and in Experiment 3 (student sample, N = 102) a cooking show or a neutral show...

'Food addiction' refers to the idea that certain highly palatable foods can trigger an addictive-like process in susceptible individuals. The aim of this study was to assess the prevalence and clinical significance of 'food addiction' symptoms in binge eating disorder (BED) using the second version of the Yale Food Addiction Scale (YFAS 2.0). Participants were 71 individuals with BED and 79 individuals with no history of an eating disorder (NED). The Eating Disorder Examination (EDE) was used to diagnose BED and to measure binge eating...

Currently, a number of questionnaires exist assessing a wide range of food parenting practices with young children. In 2016, a concept map covering three food parenting domains-coercive control, parental structure, and autonomy support-was published along with a critical review of the literature. Mapping existing food parenting questionnaires onto these concepts showed that the major focus had been on coercive control. Important aspects of the parenting process around feeding have been inadvertently omitted-parental responsiveness to children's fullness cues, parental strategies to encourage children to try new foods, and parental practices related to children's portion sizes...

By means of event-related potentials (ERPs), the present study intended to extend previous findings on how the different processing stages of attentional selection are altered by the participants' motivational state depending on their saturation level. Forty-four normal-weight (mean BMI: 21.34, SD = 1.54), healthy participants aged between 19 and 34 years were assigned to a condition of hunger or satiety. While participants performed a central oddball task, task-irrelevant pictures (food vs. neutral) were presented unilaterally (either left or right from fixation) or bilaterally...

Automatic detection of important and unexpected stimuli in the visual environment is crucial for survival. We sought to explore whether visual food stimuli are detected already in the pre-attentive stimulus processing phase, and whether hunger enhances such automatic detection. To attain these goals, we adapted an electroencephalography paradigm - visual mismatch negativity (vMMN). vMMN is a useful paradigm to study the processing of salient emotional stimuli which has not yet been applied in the context of eating behaviours...

BACKGROUND: Offering consumers the opportunity to swap to lower-salt foods while shopping has potential to reduce salt intake. Offering a wider range of alternatives which are much lower in salt could increase the magnitude of salt reduction gained but may interfere with consumers' engagement and willingness to accept swaps. OBJECTIVES: To compare the salt reduction from offering swaps to a similar product but with minimally less salt to offering swaps with a substantial salt reduction including a range of alternative foods...

This research examines how consumers' general attitude towards food fortification can lead to their intention to purchase vitamin D fortified food. Specifically, it is argued that this effect can be mediated by the perceived personal benefit of consuming vitamin D fortified food; and that the indirect effect is moderated by problem awareness and the perceived appropriateness of vitamin D fortification in a given food product category. Perceived personal benefit and problem awareness reflect the individual versus public interest to improve health, respectively...

This study obtained insight in motivation regarding food choices of Dutch employees, especially when visiting the worksite cafeteria. We also aimed to know why employees visit the worksite cafeteria. These insights are useful for intervention development to encourage healthier purchases in worksite cafeterias. We conducted seven focus groups among 45 employees of seven Dutch companies. The topics were 1) drivers and motives for food selection; 2) motives for visiting the worksite cafeteria; 3) motives for food selection in the worksite cafeteria; 4) perceptions of healthiness of products in the worksite cafeteria and 5) solutions brought up by the employees to encourage healthier eating...

Infant gaze serves as a measure of attention to food cues in adults and children and may play a role in signalling infant hunger and satiation. Maternal responsiveness to infant satiation cues, including gaze, supports healthy appetite development and may reduce obesity risk. However, mothers often experience difficulty in interpreting feeding cues, and there have been few attempts to study cues systematically. This study aimed to develop a reliable coding scheme for categorising and tracking infant gaze behaviours during complementary feeding (CF)...

OBJECTIVE: Mobile farmers markets may improve local food environments by increasing access to healthy food, yet research is limited. The purpose of this study was to describe customer characteristics and barriers to healthy eating among customers at a mobile farmers market called the Veggie Van. DESIGN: In 2016, a customer intercept design was used to survey English-speaking Veggie Van customers (n = 192; 70.5% survey response rate) aged ≥18 years on sociodemographic and health characteristics, normal daily consumption of fruit and vegetables (F/V) using the Health Information National Trends Survey screener, food acquisition and purchasing habits, and potential barriers to healthy eating...

The impact of social context on dining choices was investigated via an online experiment. Participants were assigned to different hypothetical dining partners of the same or opposite sex and varying levels of attractiveness (or no partner in a control condition) and were then asked to indicate what foods they would order if they were dining with this individual. Following a food selection task, the attractiveness of the hypothetical partner was rated, followed by the measurement of personal characteristics such as current relationship status, participant sex, and sexual orientation...

This study investigates the factors affecting consumers' motivation to engage with food product labelling in the new product context. Using yogurt as a case food, due to its positive association with health, enjoyment and convenience, this study uses eye-tracking experiments, a retrospective think-aloud protocol and semi-structured interviews, to bring to light the conscious and subconscious mechanisms associated with label usage, in order to explore the cognitive processes underlying usage of labels for new product offerings and situate these within the participant's personal context...

The goal of this study was to identify and empirically test variables that indicate how well partners in relationships know each other's food preferences. Participants (n = 2854) lived in the same household and were part of a large, nationally representative panel study in Germany. Each partner independently predicted the other's preferences for several common food items. Results show that predictive accuracy was higher for likes and for extreme and stereotypical preferences as compared to dislikes and for moderate and idiosyncratic preferences...

To assess the precision of the biological control of energy intake we performed a systematic review of studies that measured acute changes in human food intake in response to energetic errors. The imposed errors were grouped into the following categories of studies: alternate day fasting, changes in diet composition, exercise, meal skipping, overfeeding, energy substitutes, underfeeding and changes in portion size. Seven hundred thirty-nine studies published between 1980 and 2017 were identified from which the data from 592 groups from 200 studies were extracted and subjected to analysis consisting of a total of 13,203 participants...
