Based on in-store observations in three major UK retailers, in-store interviews (2019) and questionnaires filled out at home and returned (921), use of nutrition information on food labels and its understanding were investigated. Respondents' nutrition knowledge was also measured, using a comprehensive instrument covering knowledge of expert recommendations, nutrient content in different food products, and calorie content in different food products. Across six product categories, 27% of shoppers were found to have looked at nutrition information on the label, with guideline daily amount (GDA) labels and the nutrition grid/table as the main sources consulted. Respondents' understanding of major front-of-pack nutrition labels was measured using a variety of tasks dealing with conceptual understanding, substantial understanding and health inferences. Understanding was high, with up to 87.5% of respondents being able to identify the healthiest product in a set of three. Differences between level of understanding and level of usage are explained by different causal mechanisms. Regression analysis showed that usage is mainly related to interest in healthy eating, whereas understanding of nutrition information on food labels is mainly related to nutrition knowledge. Both are in turn affected by demographic variables, but in different ways. © 2010 Elsevier Ltd.

Longitudinal data indicate that our capacity for adaptive self-regulation is a relatively stable predisposition that appears in childhood and predicts future life successes. In 2004, we published the first study demonstrating decision-making deficits in overweight/obese adult women. The present study is an extension of these findings. We assessed obese women with (n = 65) and without (n = 73) binge-eating disorder (BED), and a group (n = 71) of normal-weight women, on two neuropsychological tests: the Iowa Gambling Task and a Delay Discounting measure. The BED and obese groups had worse performance scores on both tasks compared to normal controls, but did not differ from each other. These findings suggest that adaptive decision-making and the ability to delay gratification may influence our eating behaviours, particularly in a food environment where effortful control of energy intake is essential for the maintenance of a healthy body weight. There were also group differences in education level with fewer BED and obese individuals having a post-secondary degree, in accord with established links between socioeconomic status and body weight. Interestingly, when education level was added to the models, those with a higher education performed better on both tasks, and the group differences were not significant. © 2009 Elsevier Ltd.

Starting from an addiction model of obesity, the present study examined differences in attention for food-related stimuli and food intake between overweight/obese and normal-weight women under conditions of hunger and satiety. Twenty-six overweight/obese (BMI: 30.00 ± 4.62) and 40 normal-weight (BMI: 20.63 ± 1.14) females were randomly assigned to a condition of hunger or satiety. Three indexes of attention were employed, all including pictures of food items: an eye-tracking paradigm (gaze direction and duration), a visual probe task (reaction times), and a recording of electrophysiological brain activity (amplitude of the P300 event-related potential). In addition, the acute food intake of participants was assessed using a bogus taste task. In general, an attentional bias towards food pictures was found in all participants. No differences between groups or conditions were observed in the eye-tracking data. The visual probe task revealed an enhanced automatic orientation towards food cues in hungry versus satiated, and in overweight/obese versus normal-weight individuals, but no differences between groups or conditions in maintained attention. The P300 amplitude showed that only in normal-weight participants the intentional allocation of attention to food pictures was enhanced in hunger versus satiety. In hungry overweight/obese participants, the P300 bias for food pictures was not clearly present, although an increased food intake was observed especially in this group. In conclusion, various attention-related tasks yielded various results, suggesting that they measure different underlying processes. Strikingly, overweight/obese individuals appear to automatically direct their attention to food-related stimuli, to a greater extent than normal-weight individuals, particularly when food-deprived. Speculatively, hungry overweight/obese individuals also appear to use cognitive strategies to reduce a maintained attentional bias for food stimuli, perhaps in an attempt to prevent disinhibited food intake. However, in order to draw firm conclusions, replication studies are needed. © 2009 Elsevier Ltd. All rights reserved.

We examined the associations of emotional eating and depressive symptoms with the consumption of sweet and non-sweet energy-dense foods and vegetables/fruit, also focusing on the possible interplay between emotional eating and depressive symptoms. The participants were 25-64-year-old Finnish men (n=1679) and women (n=2035) from the FINRISK 2007 Study (DILGOM substudy). The Three-Factor Eating Questionnaire-R18, Center for Epidemiological Studies Depression Scale, and a 132-item Food Frequency Questionnaire were used. Emotional eating and depressive symptoms correlated positively (r=0.31 among men and women), and both were related to a higher body mass. Emotional eating was related to a higher consumption of sweet foods in both genders and non-sweet foods in men independently of depressive symptoms and restrained eating. The positive associations of depressive symptoms with sweet foods became non-significant after adjustment for emotional eating, but this was not the case for non-sweet foods. Depressive symptoms, but not emotional eating, were related to a lower consumption of vegetables/fruit. These findings suggest that emotional eating and depressive symptoms both affect unhealthy food choices. Emotional eating could be one factor explaining the association between depressive symptoms and consumption of sweet foods, while other factors may be more important with respect to non-sweet foods and vegetables/fruit. © 2010 Elsevier Ltd.

Dietary fibres have many functions in the diet, one of which may be to promote control of energy intake and reduce the risk of developing obesity. This is linked to the unique physico-chemical properties of dietary fibres which aid early signalling of satiation and prolonged or enhanced sensation of satiety. Particularly the ability of some dietary fibres to increase viscosity of intestinal contents offers numerous opportunities to affect appetite regulation. Few papers on the satiating effect of dietary fibres include information on the physico-chemical characteristics of the dietary fibres being tested, including molecular weight and viscosity. For viscosity to serve as a proxy for soluble dietary fibres it is essential to have an understanding of individual dietary fibre viscosity characteristics. The goal of this paper is to provide a brief overview on the role of dietary fibres in appetite regulation highlighting the importance of viscosity. © 2010 Elsevier Ltd.
Consumption of sugar-sweetened beverages may be one of the dietary causes of metabolic disorders, such as obesity. Therefore, substituting sugar with low calorie sweeteners may be an efficacious weight management strategy. We tested the effect of preloads containing stevia, aspartame, or sucrose on food intake, satiety, and postprandial glucose and insulin levels. Design: 19 healthy lean (BMI. =20.0-24.9) and 12 obese (BMI. =30.0-39.9) individuals 18-50 years old completed three separate food test days during which they received preloads containing stevia (290. kcal), aspartame (290. kcal), or sucrose (493. kcal) before the lunch and dinner meal. The preload order was balanced, and food intake (kcal) was directly calculated. Hunger and satiety levels were reported before and after meals, and every hour throughout the afternoon. Participants provided blood samples immediately before and 20. min after the lunch preload. Despite the caloric difference in preloads (290. kcal vs. 493. kcal), participants did not compensate by eating more at their lunch and dinner meals when they consumed stevia and aspartame versus sucrose in preloads (mean differences in food intake over entire day between sucrose and stevia. =301. kcal, p<.01; aspartame. =330. kcal, p<.01). Self-reported hunger and satiety levels did not differ by condition. Stevia preloads significantly reduced postprandial glucose levels compared to sucrose preloads (p<.01), and postprandial insulin levels compared to both aspartame and sucrose preloads (p<.05). When consuming stevia and aspartame preloads, participants did not compensate by eating more at either their lunch or dinner meal and reported similar levels of satiety compared to when they consumed the higher calorie sucrose preload. © 2010.

When inhibitory control is lacking, people are more prone to indulge in high calorie food. This research examined whether training to inhibit food-related responses renders one less susceptible to temptations of high calorie food. Trait chocolate lovers were divided into three conditions: participants either consistently inhibited responding to chocolate stimuli (chocolate/no-go condition), consistently responded to chocolate stimuli (chocolate/go condition), or responded to chocolate stimuli only during half the trials (control condition). Chocolate consumption was measured following the manipulation with a taste test. Chocolate consumption did not differ between the control condition and the chocolate/go condition, and increased as a function of dietary restraint in both conditions. In the chocolate/no-go condition, however, chocolate consumption was significantly reduced, and higher levels of dietary restraint were associated with decreased chocolate intake. These findings demonstrate that repeatedly practicing inhibitory control over food-related responses can help people regain control over the consumption of high calorie food. © 2010 Elsevier Ltd.

The present study examined whether mindfulness-based strategies can effectively reduce food cravings in an overweight and obese adult population. Individuals participating in a dietary group treatment for overweight received an additional 7-week manual based training that aimed to promote regulation of cravings by means of acceptance. The control group did not receive this additional training program. The results showed that participants in the experimental group reported significantly lower cravings for food after the intervention compared to the control group. The findings are discussed in terms of possible mechanisms like prevention of goal frustration, disengagement of obsessive thinking and reduction of automatic relations between urge and reaction. © 2010 Elsevier Ltd.

Prospective studies find that individuals with elevated dietary restraint scores are at increased risk for bulimic symptom onset, yet experiments find that assignment to energy-deficit diet interventions reduce bulimic symptoms. One explanation for the conflicting findings is that the dietary restraint scales used in the former studies do not actually identify individuals who are restraining their caloric intake. Thus, we tested whether dietary restraint scales showed inverse relations to objectively measured caloric intake in three studies. Four dietary restraint scales did not correlate with doubly labeled water estimates of caloric intake over a 2-week period (M, r = .01). One scale showed a significant inverse correlation with objectively measured caloric intake during a regular meal ordered from an ecologically valid menu (M, r = -.30), but a significant positive relation that was qualified by a significant quadratic effect, to objectively measured caloric intake during multiple eating episodes in the lab (M, r = .32). In balance, results suggest that dietary restraint scales are not valid measures of dietary restriction, replicating findings from prior studies that examined objective measures of caloric intake. © 2009 Elsevier Ltd.

The purpose of this study was threefold: to investigate the association between three parenting behaviors (parenting style, feeding style, and feeding practices), to evaluate whether these behaviors were associated with child weight, and to determine whether style (parenting and feeding) moderated the relationship between feeding practice and child weight. Ninety-nine parent-child dyads were recruited for a cross-sectional study where parents self-reported their parenting style, feeding style, and feeding practices along with demographic characteristics. Height and weight were measured for each dyad. The relationship between parenting style and feeding style showed modest agreement. Feeding style, but not parenting style, was associated with child BMI z-score while controlling for known covariates. An indulgent feeding style was associated with a higher child weight status. Multiple regression analysis demonstrated that feeding style moderated the association between restrictive feeding practices and child BMI z-score. No moderating relationship was found between feeding style and the practices of pressure to eat or monitoring and child weight. This research suggests that an indulgent feeding style may be predictive of higher child weight and that future studies should examine the possible moderating role of feeding style in the parent feeding practice-child weight relationship. © 2010 Elsevier Ltd.

Consumer demand in relation to food is shifting towards products that are safe, nutritious, and of good eating quality. Beef consumers are demanding for experience quality that matches their expectations, particularly with respect to beef tenderness. The development of a beef quality grading and guarantee system obtained through muscle profiling research, can allow the beef industry to meet these demands. A qualitative consumer study has been carried out with beef consumers in France, Spain, United Kingdom and Germany to assess their opinions about beef muscle profiling and their interest in a beef eating-quality guarantee. Findings indicate that both concepts are well accepted by European beef consumers, although not unconditional. Participants express some reserve related to the possible upgrading of lower value cuts, too much standardisation, and the fact that tenderness is to some extent subjective. They further require the system to be simple, sufficiently documented and independent-party controlled. This study indicates good opportunities for the development of a beef eating-quality guarantee system in Europe. As an increase in consumers' satisfaction could lead to higher consumption rates and industry profitability, the introduction of an eating-quality guarantee system can contribute to market development and improved competitiveness of the European beef industry. © 2009 Elsevier Ltd.

This study examines associations between parental feeding restriction at baseline and child body mass index (BMI) z-score at 3-year follow-up. Parents of 204 5-6-year-old and 188 10-12-year-old children completed the Child Feeding Questionnaire at baseline (2002/3). In 2002/3 and 2005/6, children's BMI z-score was calculated from measured height and weight. Analyses were stratified by age-group. The association of follow-up zBMI and baseline feeding restriction score was explored using (i) linear regression with adjustment for baseline zBMI and (ii) with further adjustments for baseline maternal BMI, maternal education level and child sex. Baseline restriction was associated with follow-up zBMI at 3 years in 5-6-year-old children and was largely unchanged when adjusting for child sex, maternal BMI and education. Restriction was not associated with follow-up zBMI in 10-12-year-old children. This longitudinal study adds important depth to our understanding of associations between restrictive feeding and change in zBMI, suggesting that restriction of energy-dense foods and drinks may be protective of unhealthy weight gain in younger children but may have no effect among older children. These findings support a reconsideration of the notion that restriction is likely to result in increased child weight. © 2010.

Although front-of-pack nutrition labeling can help consumers make healthier food choices, lack of attention to these labels limits their effectiveness. This study examines consumer attention to and use of three different nutrition labeling schemes (logo, multiple traffic-light label, and nutrition table) when they face different goals and resource constraints. To understand attention and processing of labels, various measures are used including self-reported use, recognition, and eye-tracking measures. Results of two experiments in different countries show that although consumers evaluate the nutrition table most positively, it receives little attention and does not stimulate healthy choices. Traffic-light labels and especially logos enhance healthy product choice, even when consumers are put under time pressure. Additionally, health goals of consumers increase attention to and use of nutrition labels, especially when these health goals concern specific nutrients. © 2011 Elsevier Ltd.

Propionate is produced along with acetate and butyrate as a result of fermentative activity of gut microflora on dietary fiber. It has long been known to exhibit hypophagic effects in ruminants, however, its potential physiological roles in non-ruminants as well as humans remained unnoticed over the years. In view of various studies pointing towards the hypophagic as well as hypocholesterolemic effects of propionate in humans, it may act as an important factor in amelioration of obesity, a lifestyle disease arising due to energy imbalance and growing at a startling rate globally. Short chain fatty acids have recently been ascribed as ligands to G-protein coupled receptors (GPRs) 41 and 43. Thus, propionate along with acetate may also be involved in the regulation of adipogenesis and adipokine release mediated via GPRs. The present review summarizes the evidence which collectively raise the possibility of propionate as a dietary factor to depress appetite and combat the obesity epidemic. © 2011 Elsevier Ltd.

The additive and interactive effect of habit strength in the explanation of young adults' fruit consumption was studied within the context of the theory of planned behaviour (TPB). Additionally, behavioural and control beliefs were modelled as predictors of profile membership based on current fruit consumption, motivation and habit strength towards fruit consumption. Cross-sectional data were available from undergraduate students (n = 538; mean age = 21.19; S.D. = 2.57) who completed measures of fruit consumption, habit strength, TPB-concepts, and behavioural and control beliefs. Data were analyzed using stepwise regression analysis, simple slope analysis, and discriminant function analysis. Results showed that, based on a significant intention × habit interaction (β = .13), the intention-fruit consumption relationship was more than twice as strong at low levels of habit strength (β = .39) than at high levels of habit strength (β = .16). Furthermore, beliefs regarding health and weight management were relatively unable to distinguish profiles created from motivation, habit strength and current fruit consumption. Rather, beliefs about controllability of fruit consumption were amongst the most consistent discriminating beliefs. Findings suggest that stronger fruit consumption habits make fruit consumption less intentional and that interventions aiming to increase fruit consumption may need to develop persuasive messages focusing on situational beliefs, rather than emphasizing health outcomes. © 2009 Elsevier Ltd.

Despite substantial evidence suggesting that a diet high in fruit and vegetables (FV) is associated with reduced risk of cancer, only 21% of children in the UK consume the recommended 5 portions of fruit or vegetables a day. This review examines the role of parenting style, feeding style and feeding practices in FV consumption in early childhood. Whilst inconsistencies in concepts and terminology cloud this literature, overall the evidence suggests that the context of an authoritative parenting and feeding style is associated with better FV consumption in the childhood years. This context is typified by emotional warmth but high expectations for children's dietary adequacy and behaviour, accompanied by specific feeding practices such as modeling consumption of FV, making FV available within the home, covertly restricting unhealthy alternative snack foods, and encouraging children to try FV. Further longitudinal and intervention studies are required to determine the efficacy of modification of parenting style and feeding practice on children's FV intake. © 2011 Elsevier Ltd.

Objective: This systematic review and meta-analysis examined whether implementation intentions are an effective tool to help people put their intentions to eat a healthy diet into practice. Additionally, it was investigated whether the quality of the outcome measures and the quality of the control conditions that are used in these studies influence implementation intentions' effectiveness. Methods: Twenty three empirical studies investigating the effect of implementation intentions on eating behavior were included. In assessing the empirical evidence, a distinction was made between studies that aim to increase healthy eating (i.e., eating more fruits) and studies that aim to diminish unhealthy eating (i.e., eating fewer unhealthy snacks). Results: Implementation intentions are an effective tool for promoting the inclusion of healthy food items in one's diet (Cohen's d = .51), but results for diminishing unhealthy eating patterns are less strong (Cohen's d = .29). For studies aiming to increase healthy eating, it was found that higher quality outcome measures and lower quality control conditions tended to yield stronger effects. Conclusion: Implementation intentions are somewhat more effective in promoting healthy eating than in diminishing unhealthy eating, although for some studies promoting healthy eating effect sizes may have been inflated due to less than optimal control conditions. © 2010 Elsevier Ltd.

To examine the association of adolescents' snack and soft drink consumption with friendship group snack and soft drink consumption, availability of snacks and soft drinks at school, and personal characteristics, snack and soft drink consumption was assessed in 749 adolescents (398 girls, 351 boys, age 12.4-17.6 years), and their friends, and snack and soft drink availability at schools was measured. In regression analysis, consumption by friends, snack and soft drink availability within school, and personal characteristics (age, gender, education level, body mass index) were examined as determinants of snack and drink consumption. Snack and soft drink consumption was higher in boys, soft drink consumption was higher in lower educated adolescents, and snack consumption was higher in adolescents with a lower body weight. Peer group snack and soft drink consumption were associated with individual intake, particularly when availability in the canteen and vending machines was high. The association between individual and peer snack consumption was strong in boys, adolescents with a lower education level, and adolescents with lower body weights. Our study shows that individual snack and soft drink consumption is associated with specific combinations of consumption by peers, availability at school, and personal characteristics. © 2010 Elsevier Ltd.
Even though eating is frequently driven by overindulgence and reward rather than by energy balance, few studies so far have analyzed decision-making processes and disturbances in feedback processing in women with binge eating disorder (BED). In an experimental study, 17 women with BED (DSM-IV) and 18 overweight healthy controls (HC) were compared in the game of dice task (GDT). This task assesses decision-making under risk with explicit rules for gains and losses. Additionally, differences in dispositional activation of the behavior inhibition and behavior approach system as well as cognitive flexibility were measured. Main results revealed that women with BED make risky decisions significantly more often than HC. Moreover, they show impaired capacities to advantageously utilize feedback processing. Even though these deficits were not related to disease-specific variables, they may be important for the daily decision-making behavior of women with BED, thus being relevant as a maintenance factor for the disorder. © 2009 Elsevier Ltd.

We tested the hypothesis that obese individuals experience greater activation of the gustatory and somatosensory cortex, but weaker activation of the striatum, in response to intake and anticipated intake of high-fat chocolate milkshake versus an isocaloric milkshake labeled low-fat and a tasteless solution using functional magnetic resonance imaging (fMRI) with 17 obese and 17 lean young women. Obese relative to lean women showed greater activation in somatosensory (Rolandic operculum), gustatory (frontal operculum), and reward valuation regions (amgydala, ventralmedial prefrontal cortex (vmPFC) in response to intake and anticipated intake of milkshake versus tasteless solution, though there was little evidence of reduced striatal activation. Obese relative to lean women also showed greater activation in the Rolandic operculum, frontal operculum, and vmPFC in response to isocaloric milkshakes labeled regular versus low-fat. Results suggest that hyper-responsivity of somatosensory, gustatory, and reward valuation regions may be related to overeating and that top-down processing influence reward encoding, which could further contribute to weight gain. © 2011 Elsevier Ltd.

This article reviews application of glutamate in food and its benefits and role as one of the common food ingredients used. Monosodium glutamate is one of the most abundant naturally occurring amino acids which frequently added as a flavor enhancer. It produced a unique taste that cannot be provided by other basic taste (saltiness, sourness, sweetness and bitterness), referred to as a fifth taste (umami). Glutamate serves some functions in the body as well, serving as an energy source for certain tissues and as a substrate for glutathione synthesis. Glutamate has the potential to enhance food intake in older individuals and dietary free glutamate evoked a visceral sensation from the stomach, intestine and portal vein. Small quantities of glutamate used in combination with a reduced amount of table salt during food preparation allow for far less salt to be used during and after cooking. Because glutamate is one of the most intensely studied food ingredients in the food supply and has been found safe, the Joint Expert Committee on Food Additives of the United Nations Food and Agriculture Organization and World Health Organization placed it in the safest category for food additives. Despite a widespread belief that glutamate can elicit asthma, migraine headache and Chinese Restaurant Syndrome (CRS), there are no consistent clinical data to support this claim. In addition, findings from the literature indicate that there is no consistent evidence to suggest that individuals may be uniquely sensitive to glutamate. © 2010 Elsevier Ltd.
Children's food preferences play a major role in their food choices and consumption. The objective of the present study was to examine if repeated tastings of selected vegetables in a school setting increased children's liking of these items. A total of 360 fourth- and fifth-grade students attending four low-income, public elementary schools in southeastern Louisiana volunteered to participate. During the spring of 2008, children were offered a taste of carrots, peas, tomatoes, and bell peppers once a week for 10 weeks. At each tasting session children recorded whether they swallowed each of the vegetables, spit it into the napkin, or did not put it in their mouth and indicated their liking for each vegetable using a Likert-type response scale. Approximately one-half of the children tasted eight of ten times during the program (46.5% for those who began disliking and 68.5% for those who began liking the vegetables). Proc Glimmix analyses indicated that for children who began the program disliking the vegetables, repeated tasting improved liking scores for carrots, peas, and tomatoes; liking for bell peppers did not change. The number of children who reported liking or liking a lot for previously disliked vegetables was greater after eight or nine taste exposures. Repeated tasting of less-liked vegetables by children in a cafeteria-based setting is a strategy to promote liking of these items and is effective in approximately half of the participants. © 2010 Elsevier Ltd.
