Abstract
Dietary intake of long-chain n-3 PUFA (n-3 PUFA), particularly EPA and DHA, has been associated with psychological well-being, but little is known about the n-3 PUFA intake of homeless youth. The current study determined the association between depression and anxiety symptoms and n-3 PUFA intake and erythrocytes status in homeless youth. Totally, 114 homeless youth aged 18-24 years were recruited from a drop-in centre. n-3 PUFA dietary intake was assessed using an FFQ, and erythrocytes status was determined by gas chromatography (GC). Linear regression models were used to determine the relationship between psychological well-being and n-3 PUFA intake and status. The mean intakes of EPA and DHA for all participants (0·06 ± 0·13 g/d and 0·11 ± 0·24 g/d) were well below recommended levels, and mean erythrocytes EPA + DHA (n-3 index) in the cohort (2·42 %) was lower than reported for healthy, housed adolescents and those with clinical depression. There was no association of n-3 PUFA intake and erythrocytes status with either depression or anxiety. However, the relationships of depression with dietary EPA (P = 0·017) and DHA (P = 0·008), as well as erythrocytes DHA (P = 0·007) and n 3-index (P = 0·009), were significantly moderated by sex even after adjusting for confounders. Specifically, among females, as the intake and status of these n-3 PUFA decreased, depression increased. Our findings show poor dietary intake and low erythrocytes status of n-3 PUFA among homeless youth, which is associated with depressive symptoms among females.

Abstract
PURPOSE Despite the lack of consensus regarding which life satisfaction domains should be included in the study of children's subjective well-being (SWB), some domains are frequently considered, such as satisfaction with health. However, some others, such as satisfaction with food, are barely taken into account, despite the impact eating habits have on children's health and well-being. We adopt a qualitative approach to explore the role food plays in children's SWB, providing for a more in-depth analysis of children's perceptions and evaluations on a still insufficiently known domain of life satisfaction. METHOD Sixteen discussion groups were held with 112 Spanish students (10-12 years old) from six schools. The transcripts were analy sed and themes reflecting the key concepts were defined using reflexive thematic analysis. RESULTS Five themes emerged from the children's discourses on the relationship between food and SWB: health, pleasure, emotions, commensality-i.e., eating together-and food-empowerment-thus offering new insights from children's perspectives. CONCLUSION Almost all of the participants established a relationship between their SWB and their eating behaviour, meaning that, within the challenges facing public health, SWB must be taken into account when promoting healthy eating programmes for children. Also, group discussion is found to be a very powerful tool for exploring topics with subjective connotations among child populations.

Abstract
BACKGROUND Emotional eaters eat to relieve their emotions. However, food also contains esthetic information. People generally perceive ugly food as unhealthy and unpalatable. Does the esthetic information of food influence an emotional eater's desire for food in a negative emotional state? In particular, do they have the same lower eating intentions for low esthetic food as non-emotional eaters? OBJECTIVE/DESIGN/MEASURES Based on these questions, the present study examined whether the esthetic value of food influences emotional eaters' desires for food. The experiment used a 2 (eating type: emotional eating vs. non-emotional eating) × 2 (food style: high esthetic vs. low esthetic) mixed experimental design. We measured the emotional and non-emotional eaters' eating intentions for different esthetic foods when experiencing negative emotions. RESULTS The results showed that emotional eaters have higher intention to eat high esthetic foods. However, they did not have a high eating intention for all foods, and their eating intention did not differ from that of non-emotional eaters when faced with low esthetic food. CONCLUSION In conclusion, food esthetic value can affect individual eating intentions. Even for emotional eaters who are in a negative mood, they also did not have a higher eating intention for low esthetic food compared with no-emotional eater. LEVEL OF EVIDENCE Level II: controlled trial without randomization.

The Influence of Consumption Context on Indulgent Versus Healthy Yoghurts: Exploring the Relationship between the Associated Emotions and the Actual Choices. SUSTAINABILITY 2022.

Abstract
This work examines the associated emotions of consumers transmitted from extrinsic attributes (fat-related nutrition claims (full-fat, low-fat, and fat-free) and ingredient features (plain, berries, and double chocolate chunk)) labelled on yoghurt packages. It differentiates by consumption context (health versus indulgent) at the time of the survey and studies the relationship between the associated emotions (e.g., positive versus negative) attached to extrinsic attributes and the actual choices. The research was conducted in the Netherlands in 2019, with 209 regular consumers of yoghurt. Participants were divided into two treatments according to each consumption context and a control group (no context); they were instructed to imagine purchasing yoghurt to consume it as a healthy snack or as a dessert or received no instructions. After choosing their preferred option from a discrete choice experiment, participants indicated how the choice made them feel from a list of emotions. The results revealed significant differences between positive emotional profiles for choosing healthy (low-fat) yoghurts with berries and negative profiles for choosing less healthy alternatives (full-fat) with double chocolate chunk sensory features. The findings from a random parameter logit model showed that participants who continuously chose the same type of yoghurt in all choice tasks selected mostly positive rather than negative emotions. The overall findings suggest that the associated emotions affect yoghurt choices. However, the emotions were mainly affected by the consumption context.

The Impact of Mood, Familiarity, Acceptability, Sensory Characteristics and Attitude on Consumers' Emotional Responses to Chocolates. Foods 2022; 11:foods11111621.

Abstract
Studies on emotions linked to sensory characteristics to understand consumers’ choice behaviour have grown in number rapidly. Internal consumer behaviour variables, namely mood, familiarity, acceptability, and attitude (MFAA), have been found to influence emotional response. The aim of this paper was to determine the impact of MFAA on consumers’ emotional responses towards chocolate as well as the effect of the sensory characteristics of chocolate on consumers’ emotional responses. Upon ethical approval, three chocolates were selected by a trained sensory panel based on 14 sensory attributes regarded relevant. Screened respondents (n = 149) completed an online survey based on the tasting of the chocolates by means of a home-use test (HUT). The questionnaire captured consumers’ mood (Quick mood scale), familiarity (QFFQ), acceptability (FACT), the sensory characteristics of the chocolate samples and emotional response (EsSense25 Profile), and lastly attitude (ACQ). Descriptive and inferential statistics were examined to answer the hypotheses of the study. The findings indicate that emotions are related to the bitter sensory attributes of chocolate and that this emotional response is influenced by MFAA variables, supporting the known fact that consumer behaviour is complex and multi-dimensional. Internal consumer behaviour variables play an important role in the emotions experienced during the consumption of chocolate. Investigating the relative importance of consumer behaviour components in sensory studies could allow for the design of food products such as chocolates based on a more “holistic” view of the consumer.

Abstract
Food can relieve an individual's emotions, especially for emotional eaters. For instance, chewing alleviates negative emotions. Solid and liquid foods comprise a huge part of our daily lives, and the chewiness of solid foods is always high. Here, we explored whether people, especially emotional eaters, have higher eating intentions to eat highly chewy foods while experiencing negative emotions by comparing their eating intentions toward solid and liquid foods. To this end, we conducted a survey of 147 participants using a questionnaire (Experiment 1) to understand their eating intention toward five types of food (purple potato, maize, black soya bean, mango, and soybean; each food group contained a solid food and a liquid food) while experiencing negative emotions. The results showed that individuals exhibited higher eating intention toward solid food compared with liquid food while experiencing negative emotions. In Experiment 2, we selected 85 and 65 high-emotional and low-emotional eaters, respectively, and further explored their preference for solid foods. The results showed that individuals with high levels of emotional eating exhibited higher intentions toward solid food while experiencing negative emotions compared with those with low levels of emotional eating. In conclusion, this study proved that individuals' higher eating intentions toward highly chewable food were pronounced among individuals with high levels of emotional eating under negative emotion conditions.

Abstract
Seaweeds are nutrient-dense marine organisms that have been proposed as a key ingredient to produce new functional foods. This study's first objective was to identify consumers' emotional responses and purchase intent towards a variety of food products containing seaweed. The secondary objective was to evaluate how hunger status and lifestyle affect consumers' emotional responses. Participants (n = 108) were asked to evaluate pictures of different food items containing seaweed (beef burger, cheddar cheese, fettuccine, fish filet, sausage, bread, yogurt, and dried seaweed) using the CATA variant of EsSense25 Profile® and a purchase-intent scale. The consumers also answered questions about their hunger status, food neophobia, food-related lifestyle, as well as open-ended comment questions about seaweed. Participants' purchase-intent scores were highest for bread and dried seaweed, which they associated with positive emotions. The participants disliked yogurt and sausage, indicating that they were disgusted with them. Participants believed seaweed could be added to fish, savoury, and cereal grains-based foods. The participants' hunger status as well as their food neophobia and lifestyle impacted their emotional responses. Future research should continue to investigate how emotions affect purchase intent, how participant's hunger status affects their emotions, and how participants' lifestyle changes how they perceive new food products.

Abstract
Disordered eating is often associated with marked psychological and emotional distress, and severe adverse impact on quality of life. Several factors can influence eating behavior and drive food consumption in excess of energy requirements for homeostasis. It is well established that stress and negative affect contribute to the aetiology of eating disorders and weight gain, and there is substantial evidence suggesting sex differences in sub-clinical and clinical types of overeating. This review will examine how negative affect and stress shape eating behaviors, and how the relationship between the physiological, endocrine, and neural responses to stress and eating behaviors differs between men and women. We will examine several drivers of overeating and explore possible mechanisms underlying sex differences in eating behavior.

Abstract
Eating behavior is not only influenced by the current energy balance, but also by the behavioral characteristics of eating. One of the recognized eating behavior constructs is ‘disinhibited eating,’ which refers to the tendency to overeat in response to negative emotional states or the presence of highly palatable foods. Food-related disinhibition is involved in binge eating, weight gain, and obesity and is also associated with the trait of impulsivity, which in turn, is linked to weight gain or maladaptive eating. However, the relationships among food-related disinhibition, the trait of impulsivity, and the neural substrates of eating behaviors in adolescence remain unclear. Therefore, we designed a functional magnetic resonance imaging (fMRI) study to examine the associations between brain responses to palatable liquid consumption and disinhibited eating behavior or impulsivity in healthy adolescents. Thirty-four adolescents (mean age ± standard deviation = 17.12 ± 1.91 years, age range = 14–19 years, boys = 15, girls = 19) participated in this study. Disinhibited eating was assessed with the disinhibition subscale of the Three-Factor Eating Questionnaire, while impulsivity was assessed using the Barratt impulsiveness scale. Participants received two fMRI sessions−a palatable liquid consumption fMRI and a resting-state fMRI. The fMRI experiment showed that increased disinhibited eating was positively associated with a greater insular response to palatable liquid consumption, while increased impulsivity was positively correlated with a greater amygdala response. The resting-state fMRI experiment showed that increased disinhibited eating was positively correlated with strengthened intrinsic functional connectivity between the insula and the amygdala, adjusting for sex (estimates of the beta coefficients = 0.146, standard error = 0.068, p = 0.040). Given that the amygdala and insular cortex are structurally and functionally connected and involved in trait impulsivity and ingestive behavior, our findings suggest that increased disinhibited eating would be associated with impulsivity via strengthened intrinsic functional connectivity between the insula and amygdala and linked to maladaptive eating.

Abstract
PURPOSE To the best of our knowledge, no scientific publications on orthorexia nervosa have been based on a French population. The goal of our study was to confirm the factor structure of the French version of the ORTO-15 questionnaire. METHODS An online survey (N = 768) was conducted asking participants (84.77% were women) to answer several questions about their dietary habits and to assess orthorexia nervosa using the ORTO-15 scale. Confirmatory factor analysis (CFA) was used for the validation. RESULTS Given our results, we deemed it necessary to adapt the French version of the ORTO-15 questionnaire by omitting three items. The CFA supported the ORTO-12-FR (composed of 12 items and addressing three domains: rational, emotional, and behavioral) as the better-fitting model, with an internal consistency of 0.73. The Comparative Fit Index value was 0.93, the Tucker-Lewis Index was 0.90, and the Root Mean-Square Error of Approximation was 0.05. CONCLUSIONS Our results provide evidence for the reliability of ORTO-12-FR with a French population. LEVEL OF EVIDENCE V, descriptive cross-sectional study.

Is comfort food actually comforting for emotional eaters? A (moderated) mediation analysis. Physiol Behav 2019; 211:112671.

Abstract
An important but unreplicated earlier finding on comfort eating was that the association between food intake and immediate mood improvement appeared to be mediated by the palatability of the food, and that this effect was more pronounced for high than for low emotional eaters [26]. This has not yet been formally tested using mediation and moderated mediation analysis. We conducted these analyses using data from two experiments on non-obese female students (n = 29 and n = 74). Mood and eating satisfaction in Study 1, and mood, tastiness and emotional eating in Study 2 were all self-reported. In Study 1, using a sad mood induction procedure, emotional eaters ate more food, and when mood was assessed immediately after food intake, 'eating satisfaction' acted as mediator between food intake and mood improvement (decrease in sadness or increase in happiness). In Study 2, where we measured the difference in actual food intake after a control or a stress task (modified Trier Social Stress Test), and assessed mood during the food intake after stress, we found significant moderated mediation. As expected, there was a significant positive mediation effect of tastiness between food intake and mood improvement in the high emotional eaters, but also a significant negative mediation effect of tastiness between food intake and mood improvement in the low emotional eaters. This suggests that tastiness promotes 'comfort' from food in female emotional eaters, but conflicts in non-emotional eaters with a tendency to eat less when stressed. In conclusion, palatable food may indeed provide comfort specifically for high emotional eaters during eating.

Abstract
Low-calorie sweetened (LCS) beverages may help consumers to satisfy hedonic food cravings without violating dieting goals, however this remains unexplored. The present research investigated the effect of priming hedonic eating motivations on ad libitum energy intake in frequent and non-consumers of LCS beverages. It was hypothesised that energy intake would be greater after the hedonic eating prime relative to a control prime in non-consumers, but that frequent LCS beverage consumers would be protected from this effect. In Study 1 (N = 120), frequent and non-consumers were exposed to either chocolate or neutral cues (craving vs. control condition) and then completed a beverage-related visual probe task with concurrent eye-tracking. Ad libitum energy intake from sweet and savoury snacks and beverages (including LCS) was then assessed. Study 2 followed a similar protocol, but included only frequent consumers (N = 172) and manipulated the availability of LCS beverages in the ad libitum eating context (available vs. unavailable). Measures of guilt and perceived behavioural control were also included. In Study 1, as hypothesised, non-consumers showed greater energy intake in the craving condition relative to the control condition, but frequent consumers had similar energy intake in both conditions. Frequent consumers (but not non-consumers) also demonstrated an attentional bias for LCS beverage stimuli compared to both sugar and water stimuli. In contrast, in Study 2 frequent consumers showed greater energy intake in the craving condition relative to the control condition; however, overall energy intake was significantly greater when LCS beverages were unavailable compared to when they were available. Ratings of guilt were higher and perceived control was lower in the LCS-unavailable condition relative to the LCS-available condition. Conclusions: LCS beverages did not consistently protect consumers from craving-induced increases in energy intake. However, frequent consumers consumed fewer calories overall when LCS beverages were available (relative to unavailable), as well as perceiving more control over their food intake and feeling less guilty.

Besides sensory characteristics of food, food-evoked emotion is a crucial factor in predicting consumer's food preference and therefore in developing new products. Many measures have been developed to assess food-evoked emotions. The aim of this literature review is (i) to give an exhaustive overview of measures used in current research and (ii) to categorize these methods along measurement level (physiological, behavioral, and cognitive) and emotional processing level (unconscious sensory, perceptual/early cognitive, and conscious/decision making) level. This 3 × 3 categorization may help researchers to compile a set of complementary measures (“toolbox”) for their studies. We included 101 peer-reviewed articles that evaluate consumer's emotions and were published between 1997 and 2016, providing us with 59 different measures. More than 60% of these measures are based on self-reported, subjective ratings and questionnaires (cognitive measurement level) and assess the conscious/decision-making level of emotional processing. This multitude of measures and their overrepresentation in a single category hinders the comparison of results across studies and building a complete multi-faceted picture of food-evoked emotions. We recommend (1) to use widely applied, validated measures only, (2) to refrain from using (highly correlated) measures from the same category but use measures from different categories instead, preferably covering all three emotional processing levels, and (3) to acquire and share simultaneously collected physiological, behavioral, and cognitive datasets to improve the predictive power of food choice and other models.

An Electronic Ecological Momentary Assessment Study to Examine the Consumption of High-Fat/High-Sugar Foods, Fruits/Vegetables, and Affective States Among Women. JOURNAL OF NUTRITION EDUCATION AND BEHAVIOR 2018; 50:626-631.

Abstract
OBJECTIVE To examine the associations between high-fat/high-sugar foods (HFHS) and fruit and vegetable (FV) consumption and affective states in women. METHODS The researchers used electronic ecological momentary assessment to capture HFHS and FV consumption in the past 2 hours (predictor) and current affective states (outcome) across 1 week among 202 women. Multilevel linear regression was conducted. Weight status was tested as a moderator. RESULTS Consumption of FV in the past 2 hours was positively associated with feeling happy (P < .05). Women who consumed more HFHS or fewer FV than others in the study reported higher average sadness (both P < .05). Overweight or obese women who reported more frequent HFHS consumption than others had higher average stress than normal weight women (P < .05). CONCLUSIONS AND IMPLICATIONS The association between HFHS consumption and stress might be stronger in overweight or obese than normal weight women. Future studies could further enhance the electronic ecological momentary assessment method to explore other time-varying moderators and mediators of food consumption and affect.

Abstract
The present study sets out to further elucidate the complex relationship between daily hassles, snacking, and negative affect (NA). The aim of the present study was to examine whether or not moment-to-moment energy intake from snacks moderates the association between momentary stress and NA. And, if so, can this moderating effect be replicated by using the amount of macronutrient intake (i.e., carbohydrates, fat, and protein) as moderator on the association between momentary stress and NA? Adults (N = 269), aged 20-50 years, participated in this study. Stress, NA, and snack intake were assessed 10 times a day for 7 consecutive days in daily life with an experience sampling smartphone application. Multilevel regression analyses were performed to assess the hypothesized associations. Our study revealed a dampening effect of snacking on negative affective stress reactivity. However, this dampening effect could not be replicated by the amount of macronutrient intake from snacks. On the contrary, the amount of carbohydrates has an enhancing effect on negative affective stress reactivity. In the end, our study suggests that the critical question is which mechanisms are decisive in the dampening role of snacking on stress reactivity. A multidisciplinary approach may provide a full perspective.

Abstract
Night eating syndrome (NES) is characterized by excessive evening and/or nocturnal eating episodes. Studies indicate an attentional bias towards food in other eating disorders. For NES, however, evidence of attentional food processing is lacking. Attention towards food and non-food stimuli was compared using eye-tracking in 19 participants with NES and 19 matched controls without eating disorders during a free exploration paradigm and a visual search task. In the free exploration paradigm, groups did not differ in initial fixation position or gaze duration. However, a significant orienting bias to food compared to non-food was found within the NES group, but not in controls. A significant attentional maintenance bias to non-food compared to food was found in both groups. Detection times did not differ between groups in the search task. Only in NES, attention to and faster detection of non-food stimuli were related to higher BMI and more evening eating episodes. The results might indicate an attentional approach-avoidance pattern towards food in NES. However, further studies should clarify the implications of attentional mechanisms for the etiology and maintenance of NES.

Abstract
Food intake influences human cognition, olfaction, hunger, and food craving. However, little research has been done in this field to elucidate the effects of different nutrients. Thus, the goal of our study was to investigate the effects of oral ingestion of different nutrient solutions on olfactory, cognitive, metabolic and psychophysical function. Twenty healthy men participated in our study employing a double-blind, cross-over, repeated measurement design. Participants were tested on four different study days. Each day participants received, in randomized order, one of three isocaloric (protein, carbohydrate or fat 600 kcal, 1,500 mL) solutions or a placebo. Olfactory and cognitive tests (monitoring only) were conducted three times, i.e., 60 min before the beginning of nutrient intake, following oral ingestion of the solution and 60, and 240 min after. Psychophysical and metabolic function tests (active grehlin, desacyl ghrelin, insulin, glucagon, glucose, triglyceride, urea) were performed 7 times on each examination day (observation period: −60 min, 0 = solution intake, +60, +120, +180, +240, and +300 min). Ratings of hunger and food craving significantly differed over the observation period with lowest ratings following application of the protein solution. Highest ratings of craving were found following placebo intake. We further observed a significant positive correlation of active grehlin with hunger and fat, protein and sweets craving for each nutrient solution. Active grehlin significantly correlated with carbohydrate craving for carbohydrate and fat solution and with vegetable craving for fat solution only. Hunger hormone levels, hunger and food craving ratings demonstrated that the hierarchical order that appears in satiating efficiencies of isovolumetric-isocaloric ingested macronutrients is protein > fat > carbohydrate. Our study reveals that the type of nutrient exerts a significant influence on metabolic parameters, hunger and food craving.

Abstract
Abstract: According to the phenomenological approach, observing a phenomenon through the perspective of those who lived it may be necessary to acquire fully comprehension of it. Therefore, to fully understand the eating behavior during anorexia nervosa and during its recovery, this study investigated individual perceptions and feelings of three women recovering from anorexia nervosa. This study is characterized as a qualitative research with phenomenological approach. The data were collected through interviews and analyzed following steps proposed by phenomenology researchers. During the anorexia nervosa experience, food restriction and irregular meal patterns were observed. Controlling food intake was associated with happiness. Guilt, anguish, sadness, fear and anger were associated with eating, and food was considered a villain. An obsessive thinking about food and a paradox between liking to eat and not wanting to eat were also observed. During recovery, it is important to have a more flexible eating behavior without negative feelings regarding food; however, feelings of guilty and fear were still detected. Perceptions about contact with nutritionists revealed the use of ineffective strategies. Although similarities were found in all reports, every woman had their own particular and singular experience. Rescuing their memories and experiences through their speech was important to fully understand and comprehend these personal experiences, and this complete understanding may enable health professionals to act more efficiently in the treatment of this complex phenomenon.

Abstract
Studies indicate an attentional bias towards food in binge-eating disorder (BED); however, more evidence on attentional engagement and disengagement and processing of multiple attention-competing stimuli is needed. This study aimed to examine visual attention to food and non-food stimuli in BED. In n = 23 participants with full-syndrome and subsyndromal BED and n = 23 individually matched healthy controls, eye-tracking was used to assess attention to food and non-food stimuli during a free exploration paradigm and a visual search task. In the free exploration paradigm, groups did not differ in their initial fixation position. While both groups fixated non-food stimuli significantly longer than food stimuli, the BED group allocated significantly more attention towards food than controls. In the visual search task, groups did not differ in detection times. However, a significant detection bias for food was found in full-syndrome BED, but not in controls. An increased initial attention towards food was related to greater BED symptomatology and lower body mass index (BMI) only in full-syndrome BED, while a greater maintained attention to food was associated with lower BMI in controls. The results suggest food-biased visual attentional processing in adults with BED. Further studies should clarify the implications of attentional processes for the etiology and maintenance of BED.

The Effects of a Normal Rate versus a Slow Intervalled Rate of Oral Nutrient Intake and Intravenous Low Rate Macronutrient Application on Psychophysical Function – Two Pilot Studies.

Abstract
Stomach distension and energy per time are factors influencing satiety. Moreover, different rates of nutrient intake induce different stomach distension. The goal of our studies was to elucidate the influence of different oral rates of nutrient intake (normal rate versus slow intervalled rate; study I) and intravenous low rate macronutrient application (protein, carbohydrate, fat) or placebo (study II) on psychophysical function. The pilot studies investigated the effects of 1) study I: a mixed nutrient solution (1/3 protein, 1/3 fat, 1/3 carbohydrates) 2) study II: intravenous macronutrient infusions (protein, carbohydrate, fat) or placebo on psychophysical function (mood, hunger, food craving, alertness, smell intensity ratings and hedonic ratings) in human subjects. In study I 10 male subjects (age range: 21–30 years) completed the study protocol participating in both test conditions and in study II 20 male subjects (age range: 19–41 years) completed the study protocol participating in all test conditions. Additionally, metabolic function was analyzed and cognitive and olfactory tests were conducted twice starting 100 min before the beginning of the intervention and 240 min after. Psychophysical (mood, hunger, fat-, protein-, carbohydrate-, sweets- and vegetable-craving), alertness and metabolic function tests were performed seven times on each examination day. Greater effects on hunger and food cravings were observed for normal rate of intake compared to slow intervalled rate of intake and intravenous low rate macronutrient application. Our findings potentially confirm that volume of the food ingested and a higher rate of energy per time contribute to satiety during normal rate of food intake, while slow intervalled rate of food intake and intravenous low rate macronutrient application showed no effects on satiation. Our results motivate the view that a certain amount of volume of the food ingested and a certain energy per time ratio are necessary to reduce hunger and food craving.

Abstract
The P1vital® Oxford Emotional Test Battery (ETB) comprises five computerized tasks designed to assess cognition and emotional processing in human participants. It has been used in between-subjects experimental designs; however, it is unclear whether the battery can be used in crossover designs. This is of particular importance given the increasing use of ETB tasks for repeated assessment of depressed patients in clinical trials and clinical practice. In addition, although satiety state has been reported to affect performance on some cognitive and emotional tasks, it is not known whether it can influence performance on the ETB. Two studies explored these issues. In Experiment 1, 30 healthy women were tested on the ETB on 4 separate occasions (each a week apart) in a within-subjects design. In Experiment 2, another 30 healthy women were randomized to either a satiated or a hungry condition, where they were given an ad libitum lunch of cheese sandwiches, before (satiated) or after (hungry) they were asked to complete the ETB. Experiment 1 demonstrated good test–retest reliability for the ETB. One of the tasks was free from practice effects, whilst performance on the other four tasks stabilized after the first two sessions. In Experiment 2, eating to satiety only affected performance on a single ETB task. These results suggest that the ETB can be used in crossover designs after two initial training sessions. Further, as a robust satiety manipulation had only a limited effect on a single ETB task, it is unlikely that appetitive state will confound ETB performance.

Abstract
To date, there have been no studies that have explicitly examined the effect of awareness on the consumption of food from a Universal Eating Monitor (UEM - hidden balance interfaced to a computer which covertly records eating behaviour). We tested whether awareness of a UEM affected consumption of a pasta lunch and a cookie snack. 39 female participants were randomly assigned to either an aware or unaware condition. After being informed of the presence of the UEM (aware) or not being told about its presence (unaware), participants consumed ad-libitum a pasta lunch from the UEM followed by a cookie snack. Awareness of the UEM did not significantly affect the amount of pasta or cookies eaten. However, awareness significantly reduced the rate of cookie consumption. These results suggest that awareness of being monitored by the UEM has no effect on the consumption of a pasta meal, but does influence the consumption of a cookie snack in the absence of hunger. Hence, energy dense snack foods consumed after a meal may be more susceptible to awareness of monitoring than staple food items.

Abstract
This study examined contributions of environmental and personal factors (specifically, food availability and expense, daily hassles, self-efficacy, positive and negative affect) to within-person and between-person variations in snack food intake in 100 African American women. Participants were signaled at random five times daily for seven days to complete a survey on a study-provided smartphone. Women reported consuming snack foods at 35.2% of signals. Easier food availability accounting for one's usual level was associated with higher snack food intake. Being near outlets that predominately sell snacks (e.g., convenience stores), while accounting for one's usual proximity to them, was associated with higher snack food intake. Accounting for one's usual daily hassle level, we found that on days with more frequent daily hassles snack food intake was higher. The positive association between within-person daily hassles frequency and snack food intake was stronger when foods were easily available. Public and private policies to curb ubiquitous food availability and mobile health interventions that take into account time-varying influences on food choices and provide real-time assistance in dealing with easy food availability and coping with stressors may be beneficial in improving African American women's day to day food choices.

Abstract
Food is a potent natural reward and food intake is a complex process. Reward and gratification associated with food consumption leads to dopamine (DA) production, which in turn activates reward and pleasure centers in the brain. An individual will repeatedly eat a particular food to experience this positive feeling of gratification. This type of repetitive behavior of food intake leads to the activation of brain reward pathways that eventually overrides other signals of satiety and hunger. Thus, a gratification habit through a favorable food leads to overeating and morbid obesity. Overeating and obesity stems from many biological factors engaging both central and peripheral systems in a bi-directional manner involving mood and emotions. Emotional eating and altered mood can also lead to altered food choice and intake leading to overeating and obesity. Research findings from human and animal studies support a two-way link between three concepts, mood, food, and obesity. The focus of this article is to provide an overview of complex nature of food intake where various biological factors link mood, food intake, and brain signaling that engages both peripheral and central nervous system signaling pathways in a bi-directional manner in obesity.

López-Guimerà G, Dashti HS, Smith CE, Sánchez-Carracedo D, Ordovas JM, Garaulet M. CLOCK 3111 T/C SNP interacts with emotional eating behavior for weight-loss in a Mediterranean population. PLoS One 2014; 9:e99152. [PMID: 24905098 PMCID: PMC4048277 DOI: 10.1371/journal.pone.0099152] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2013] [Accepted: 05/12/2014] [Indexed: 12/27/2022] Open
Abstract
OBJECTIVE The goals of this research was (1) to analyze the role of emotional eating behavior on weight-loss progression during a 30-week weight-loss program in 1,272 individuals from a large Mediterranean population and (2) to test for interaction between CLOCK 3111 T/C SNP and emotional eating behavior on the effectiveness of the weight-loss program. DESIGN AND METHODS A total of 1,272 overweight and obese participants (BMI: 31±5 kg/m2), aged 20 to 65 years, attending outpatient weight-loss clinics were recruited for this analysis. Emotional eating behavior was assessed by the Emotional Eating Questionnaire (EEQ), a questionnaire validated for overweight and obese Spanish subjects. Anthropometric measures, dietary intake and weight-loss progression were assessed and analyzed throughout the 30-week program. Multivariate analysis and linear regression models were performed to test for gene-environment interaction. RESULTS Weight-loss progression during the 30-week program differed significantly according to the degree of emotional eating behavior. Participants classified as 'very emotional eaters' experienced more irregular (P = 0.007) weight-loss, with a lower rate of weight decline (-0.002 vs. -0.003, P<0.05) in comparison with less emotional eaters. The percentage of weight-loss was also significantly higher in 'non-emotional eaters' (P = 0.009). Additionally, we identified a significant gene-environment interaction associated with weight-loss at the CLOCK 3111 T/C locus (P = 0.017). By dichotomizing the emotional eating behavior score, linear regression analysis indicated that minor C allele carriers with a high emotional score (> = 11), lost significantly less weight than those C carriers with a low emotional score (<11) (P = 0.005). CONCLUSIONS Emotional eating behavior associates with weight-loss pattern, progression and total weight-loss. Additionally, CLOCK 3111 T/C SNP interacts with emotional eating behavior to modulate total weight loss. These results suggest that the assessment of this locus and emotional eating behavior could improve the development of effective, long-tern weight-management interventions.

Abstract
PURPOSE This pilot study sought to determine how meal consumption impacts affective states for treatment-seeking individuals with eating disorders (ED). METHODS Participants with heterogeneous ED diagnoses completed the State-Trait Anxiety Inventory, Positive and Negative Affect Schedule, and Profile of Mood States measures before and immediately after meal consumption. RESULTS Meal consumption was associated with significant decreases in negative affect and total mood disturbance for individuals with binge eating disorder (BED). Decreases in negative affect across meal time for individuals with BED were significantly different from increases in negative affect for participants with anorexia nervosa (AN) and bulimia nervosa (BN). CONCLUSION Findings indicate that individuals with BED have significantly different affective responses to eating non-binge meals than individuals with AN or BN. Data suggest changes in negative affect following meal consumption may be specific to certain ED diagnoses. Results provide preliminary evidence consistent with the idea that emotion states may function as maintenance mechanisms for psychopathology among ED diagnoses. Limitations and future directions pertaining to food-mood relationships for individuals with ED are discussed.

Abstract
We tested whether exposure to the ultimate symbols of an impatience culture—fast food—undermines people’s ability to experience happiness from savoring pleasurable experiences. Study 1 found that the concentration of fast-food restaurants in individuals’ neighborhoods predicted their tendencies to savor. Study 2 revealed that exposure to fast-food primes impeded participants’ ability to derive happiness from pictures of natural beauty. Study 3 showed that priming fast food undermined positive emotional responses to a beautiful melody by inducing greater impatience, measured by both subjective perception of time passage and self-reports of impatience experienced during the music. Together, these studies show that as pervasive symbols of impatience, fast food can inhibit savoring, producing negative consequences for how we experience pleasurable events.

Abstract
The need for the development of appropriate guidelines for effective or safe use of antioxidants and herbs has always been a concern, especially for the alternative medicine practices. Computer Meridian Diagnostic (CMD) is one of emerging computer-based diagnostic technologies available to alternative medicine practitioners. However, case report of the agents monitored with CMD is uncommon; and concerted effort to bring this into conventional medical practice is yet to be. This hypothesis builds on an anecdotal observation of anti-stress effect monitored with CMD, with a view to highlight a potential tool that requires expatiation, as well as proof of concept and validation studies for possible integration in conventional and traditional medicine practices for therapeutic monitoring.

Abstract
OBJECTIVE The study objectives were to evaluate the relationship between social anxiety, binge eating, and emotional eating in overweight and obese individuals and to evaluate the relationship between weight and social anxiety. METHODS Using an internet based survey, overweight and obese men and women (n=231; mean age=36.0±12.8; mean BMI=33.7 kg/m(2)±6.7) completed several self-report measures including: social anxiety, social physique anxiety, binge eating, and emotional eating. The relationships among variables were evaluated using Spearman's correlations, ANOVAs, and linear and logistic regression equations. RESULTS Clinically significant levels of social anxiety were reported in 59% of participants, and binge eating disorder criteria were met by 13%. Social anxiety was significantly associated with binge eating (r=.36; OR=1.06, CI=1.02-1.10) and emotional eating (r=.46; β=0.36), but was not associated with restrained eating. The association between social physique anxiety and emotional and binge eating did not remain significant in regression equations. BMI was associated with binge eating (r=.19) but not emotional eating. Level of social anxiety was not significantly higher among extremely obese participants, compared to overweight and obese participants. CONCLUSIONS In this study, social anxiety was associated with binge eating and emotional eating in overweight and obese men and women. When appropriate, interventions could address social anxiety as a barrier to normative eating patterns and weight loss.

Abstract
OBJECTIVE While high levels of dietary restraint do not appear to reflect actual caloric restraint, it has been found to be a risk factor for a wide array of maladaptive eating patterns. These findings raise the question what, if not caloric restriction, dietary restraint entails. We propose that the very finding that restrained eaters do not eat less than they intend to do can provide an answer. Based on this disparity between the intention to restrain oneself and actual behaviour, we therefore hypothesised that high levels of restraint are associated with eating-related guilt. METHOD Three studies (N = 148) using unobtrusive measures of food intake; different restraint scales; and different measures of guilt tested whether restraint is related to eating-related guilt. RESULTS Results indicated that restraint was not associated with food intake, but instead was associated with increased levels of guilt after eating. Guilt was explicitly related to food intake. Moreover, the observed guilt could not be attributed to a general increase in negative affect. CONCLUSION The results of these studies suggest that restraint is not an indicator of actual restricted food intake, but rather a reflection concerns about food and eating manifested in eating-related guilt.

Abstract
The current work examined the extent to which nicotine level affects the receptiveness of cigarette smokers to a compelling (strong) or a specious (weak) antismoking, public service announcement (PSA). The combination of nicotine loading (i.e., having just smoked a cigarette) and a strong antismoking PSA led to significantly more negative implicit evaluations of cigarettes; however, explicit evaluations were not changed by nicotine level or PSA quality. Smokers' implicit evaluations of cigarettes were affected only by compelling PSAs when they had recently smoked but not when they were nicotine deprived or when they viewed weak PSAs. Because implicit evaluations of cigarettes predict deliberate smoking-related decisions, it is important to understand which factors can render these implicit evaluations relatively more negative.

Abstract
The aims of this study were firstly to evaluate the psychometric properties of the French version of the Orientation towards Chocolate Questionnaire (OCQ), secondly to examine differences in chocolate craving as a function of weight status, and thirdly to examine the OCQ craving dimensions as predictors of body dissatisfaction and disordered eating. Participants included 247 female students from the University of Toulouse, France, who completed measures of chocolate craving, body dissatisfaction, bulimia, drive for thinness, and emotional eating, and for whom body mass index (BMI) was available. Confirmatory factor analysis supported the three-factor model of the OCQ, with guilt, approach, and avoidance subscales. Patterns of endorsement of chocolate craving dimensions differed according to weight status, with ambivalence present only amongst overweight participants. Guilt and approach were positively associated with disordered eating, whereas avoidance was negatively associated with bulimia. These results confirm the validity and reliability of the French version of the OCQ and highlight strong associations between chocolate craving dimensions and disordered eating patterns.

Abstract
In many parts of the world the prevalence of a sedentary lifestyle in combination with high consumption of food has increased, which contributes to increased risk for becoming overweight. Our primary aim was, in an intervention, to examine the influence on health related quality of life (HRQoL) and mood in young normal weight subjects of both sexes, when adopting an obesity provoking behaviour by increasing the energy intake via fast food and simultaneously adopting a sedentary lifestyle. A secondary aim was to follow-up possible long-term effects on HRQoL and mood 6 and 12 months after this short-term intervention. In this prospective study, 18 healthy normal weight subjects (mean age 26±6.6 years), mainly university students were prescribed doubled energy intake, and maximum 5000 steps/day, during 4 weeks. An age and sex matched control group (n=18), who were asked to have unchanged eating habits and physical activity, was recruited. Before and after the intervention questionnaires including Short Form-36, Hospital Anxiety Depression scale, Center of Epidemiological Studies Depression scale, Sense of Coherence and Mastery scale were completed by the subjects in the intervention group and by the controls with 4 weeks interval. Six and 12 months after the intervention the subjects underwent the same procedure as at baseline and the controls completed the same questionnaires. During the intervention, subjects in the intervention group increased their bodyweight and developed markedly lower physical and mental health scores on Short Form-36 as well as depressive symptoms while no changes appeared in the controls. The increase of depressive symptoms was associated with increases of energy intake, body weight and body fat. When followed up, 6 and 12 months after the intervention, physical and mental health had returned completely to baseline values, despite somewhat increased body weight. In conclusion, adopting obesity provoking behaviour for 4 weeks decreases HRQoL and mood in young normal weight subjects. The effect is temporary and when followed up 6 and 12 months after the short-term intervention no remaining influence is found.

Abstract
BACKGROUND Approved for treatment of treatment-resistant depression and for epilepsy, vagus nerve stimulation (VNS) therapy involves stimulation of the vagus nerve, affecting both mood and appetite regulating systems. VNS is associated with changes in food intake and weight loss in animals. Studies of its impact on food intake and weight with humans are limited. It is not known whether or how VNS influences emotional response to food, but vagus afferents project to regions in the insula involving satiety and taste. METHOD Thirty-three participants were recruited for three groups: depressed patients undergoing VNS therapy, depressed patients not undergoing VNS therapy, and healthy controls. All participants viewed images of foods twice in random order. When applicable, VNS devices were turned on for one viewing and off for the other. Participants were instructed to rate immediately after the viewings how each picture made them feel on a visual analog on three dimensions (unhappy to happy, calm to aroused, and small/submissive to big/domineering). RESULTS Controlling for time since last meal, a significant main effect was found for arousal ratings in response to sweet food images. Post-hoc analyses indicated that the VNS group demonstrated significant changes in arousal ratings between paired food image viewings compared to controls. Sixty-four percent of VNS participants demonstrated increases and 36% demonstrated decreases in arousal. Higher body mass indexes and greater levels of self-reported sweet cravings were associated with increased arousal during VNS activation. CONCLUSIONS This study was the first to examine the effects of acute left cervical VNS on emotional ratings of food in adults with major depression. Results suggest that VNS device activation may be associated with acute alteration in arousal response to sweet foods among depressed patients. Future research is needed to replicate these findings and to assess how activation of the vagus nerve affects eating and weight.

Abstract
Purpose: The symbolic meanings that youth associate with food were explored, as were barriers to accessing healthy foods.Methods: Qualitative methods and a constructivist approach were employed, and data were collected through semi-structured interviews and a card-sorting activity. Thirteen adolescents aged 13 to 15 (seven girls, six boys) were recruited through public schools and posters displayed in community settings. Thematic analytical techniques were used to analyze the data.Results: Participants classified foods into healthy and unhealthy groups, as well as into an “in-between” group that included nutritionally enhanced foods. Healthy and unhealthy foods were linked to a variety of physical, social, and emotional meanings. Some meanings associated with foods were also discussed in gendered terms, and numerous barriers to accessing healthy foods were reported.Conclusions: Foods hold multiple meanings for youth. Programs and policies aimed at fostering healthy eating need to capitalize on positive associations related to healthy foods. Negative associations related to healthy foods need to be acknowledged and strategies developed to recast such linkages. Likewise, the positive associations linked to unhealthy foods need to be addressed. Strategies also need to be developed to ensure access to healthy foods in all settings, especially within schools and community leisure settings.

Abstract
RACIONAL: A obesidade é distúrbio de origem multifatorial complexa que congrega aspectos de ordem psicológica, social, biológica e requer abordagem multidisciplinar. É considerada fator de risco para a compulsão alimentar, de modo que a dinâmica emocional do obeso contribuiria para desencadear o ato compulsivo. OBJETIVO: Analisar os indícios de compulsão alimentar em pacientes submetidos à cirurgia bariátrica, antes e dois anos após a operação. MÉTODOS: Foi realizado estudo prospectivo em 50 pacientes submetidos à cirurgia bariátrica pela técnica de Fobi-Capella. Os instrumentos de avaliação psicológica, aplicados antes e após dois anos, foram o teste das Pirâmides Coloridas de Max Pfister e entrevista clínica semi-estruturada. O teste foi aplicado antes e após a operação para identificar indícios de compulsão. A entrevista somente no pós-operatório. RESULTADOS: Citando somente os dados principais, os dados mostraram estabilidade e capacidade para lidar com conflitos em 16% dos pacientes antes da operação e em 10% após. Para a capacidade de controle e adaptação, 36% dos pacientes apresentavam fortes indícios de atitude de controle e rigidez antes da operação e 32% após. Quanto aos indicadores de impulsividade, agressividade e irritabilidade, houve fortes indícios de atitudes agressivas e impulsivas em 28% antes da operação e em 36% após. Quanto ao comportamento beliscador, eram presentes em 94% dos pacientes no pré-operatório e em 60% no pós. Quanto à preferência alimentar, foi a por alimentos calóricos sem menção à bebidas alcoólicas no pré-operatório, e no pós-operatório por alimentos de fácil ingestão. Quanto ao motivo atribuído aos episódios compulsivos, antes da operação 4% dos pacientes relataram estado de nervosismo, 24% afirmaram distúrbios de humor e 52% identificaram sentimentos de impotência ou submissão. No pós, foram 10%, 28% e 38%. Quanto às respostas compensatórias, eram elas ingestão de doces em 12%; ingestão de petiscos em 2% e comer indiscriminadamente tudo que estivesse ao alcance em 64% dos pacientes. Após, 18%, 10% e 22%. CONCLUSÃO: Os pacientes apresentam indícios de compulsão alimentar antes e após a operação. Ela está relacionada a aspectos psicológicos. Os hábitos e preferências alimentares modificam-se após a operação, de modo que os pacientes passam a consumir alimentos de fácil ingestão frente a situações que os faziam comer compulsivamente, não sendo observado trocas de compulsão. O comportamento alimentar inadequado persiste ou é agravado após a operação.

Abstract
Eating behaviour depends partly on food preference, which may be determined by different types of emotions. Among the emotions generated by food, disgust and pleasure are common and can lead to increased and reduced food consumption. We tested the hypothesis that (1) elderly men and women felt different emotions towards food, and (2) low energy intake is related to negative emotions towards food. In February 2004, a convenience sample of elderly participants was recruited locally by telephone. Food intake of 52 elderly people, aged 63-80 years, was monitored throughout each day for one week and made it possible to assign the elderly people to two groups (low and high energy intake from food consumption data). One month later, each of them assessed their likes or dislikes towards 30 food pictures (vegetables, cheeses, fruits, starchy foods, sweets, meat, fish, offal and eggs) using 19 emotional words (eight words with a positive valence: 'to like', 'thrilled', 'satisfaction', 'surprise', 'serene', 'amused', 'pride', 'interest', and 11 other words with a negative valence: 'disgust', 'indifference', 'guilt', 'uneasiness', 'nostalgia', 'impatience', 'doubt', 'frustration', 'embarrassment', 'disappointment' and 'lassitude'. The emotional intensities experienced with the different pictures were analysed by ANOVA for each group (men and women, small and big eaters). There were differences in likes and dislikes between men and women. Both guilty and liking scores towards food were generally higher in women than in men. Small eaters felt more doubt, unease, disappointment and indifference towards food than big eaters. In conclusion, the report of low food intake was related to more negative emotions towards foods that might be associated with the willingness to restrict food intake or to undernutrition.

Abstract
There is a dearth of qualitative research exploring eating disordered individuals' emotional responses to the sight of different types of food. In this study we asked 10 adult women diagnosed with bulimia nervosa, anorexia nervosa or an eating disorder not otherwise specified (EDNOS) to articulate their thoughts whilst viewing slides of a range of different foodstuffs, during an in-depth interview session. The data were transcribed and subjected to qualitative analysis. A core theme of 'Control' was identified. Whilst control has been previously acknowledged in the literature as an important aspect of eating disordered behaviour, this is the first report to link control with negative emotional responses to the sight of food. Clinically, an exploration of the notion of control and how it relates to particular foods may be beneficial in therapy.

Abstract
Eating behaviour depends partly on food preference, which is itself determined by different types of emotions. Among the emotions generated by food, disgust with red meat is common in women and can lead to reduced meat consumption. We tested the hypothesis that low meat intake is related to different negative emotions towards meat but does not affect the emotions expressed towards other food categories. Food intake of sixty women was followed throughout each day for 1 week and allowed us to assign women to two groups (low v. high meat-eating women). They were then invited to assess the intensity of twenty-six emotions described by words and induced by thirty food pictures. We determined the number of necessary dimensions to describe the space created by the twenty-six words. The results showed differences in emotions between the low and high meat-eating women. As expected, there were overall differences in the emotions generated by the thirty food pictures. Six clusters of emotions were necessary and sufficient to summarise the emotional space. These dimensions were described by ‘disappointment’, ‘satisfaction’, ‘guilt’, ‘doubt’, ‘amused’ and ‘indifference’. As expected, the low meat-eating women felt more ‘disappointment’, ‘indifference’ and less ‘satisfaction’ towards meat than did the high meat-eating women. However, the low meat-eating women also stated other negative emotions such as ‘doubt’ towards some starchy foods. The only foods that they liked more than high meat-eating women were pears and French beans. In conclusion, low meat consumption was associated with specific negative emotions regarding meat and other foods.
