Appetite

Past work suggested that psychological stress, especially in the context of relationship stress, is associated with increased consumption of energy-dense food and when maintained for long periods of time, leads to adverse health consequences. Furthermore, this association is moderated by a variety of factors, including emotional over-eating style. That being said, few work utilized a dynamical system approach to understand the intraindividual and interindividual fluctuations within this process. The current study utilized a 14-day daily diary study, collected between January-March 2020, where participants reported their partner's negative relationship behavior and their own snacking behavior...

In contemporary societies with diverse but often conflicting values attached to eating, it is important to scrutinise what eating well means to a given population. While such attempts have been pioneered, mostly in Western countries, Asia has been rarely explored. Moreover, food scholars in Western countries have called for in-depth analysis of the impacts of food modernisation on our everyday eating models, but empirical data about Asia and its implications for the plurality of food modernisation have been limited...

Large cities are home to several groups of immigrants who undergo important changes in their environmental conditions and lifestyles that significantly modify their risk of chronic diseases. Quantitative evidence indicates that both their health and diet worsen over time; much less is known about the qualitative mechanisms that cause these changes. The aim of this article is to understand how immigrants in the city of Madrid perceive the relation between the urban food environment and dietary behaviour. Based on a Social Ecological Framework, we conducted a secondary qualitative analysis derived from data from 41 immigrant residents, collected in eight focus groups (FGs), conducted in two neighbourhoods in the city of Madrid...

The rapid demographic transition in developing countries has always posed a challenge for the social and economic policies of these nations. The increase in longevity poses new challenges for understanding dietary consumption among different age groups at the old age population. The aim of this study was to evaluate the reasons for food choice and the composition of nutritional intake of older adults and its relationship to individual characteristics. Community-living older adults aged 60 and older were interviewed in their homes at the southeastern region of Brazil, between December 2021 and February 2022...

Accumulating evidence from both cross-sectional and cue-reactivity studies supports the application of the Ambivalence Model of Craving (AMC) from the substance use literature to food craving. The focus of this extant work has been on the association between the two dimensions of food craving (approach and avoidance) and disordered eating behaviors. The present study extended existing validity data by investigating approach and avoidance food craving profiles and their associations with 1) disordered eating behaviors and 2) thinness/restriction and eating expectancies - a risk factor for disordered eating that is explicitly described by the AMC...

The promotion of meat substitutes to reduce meat intake is a promising way to reduce the environmental and public health externalities of meat consumption while preserving the important role of taste and texture in meat products. However, the market for meat substitutes is developing more slowly than expected. Therefore, we analyze the factors associated with the heterogeneity in meat substitute consumption in Germany, a country where meat traditionally plays an important role. We use revealed preference data on meat substitute sales from 1,025 individual retailers, sociodemographic data, and election results from 92 regions in Germany over the period 2017-2021, to analyze whether differences in meat substitute consumption are associated with consumers' political orientation (liberal/left or conservative/right) and socio-demographic variables...

The complications of obesity extend beyond the periphery to the central nervous system (CNS) and include an increased risk of developing neuropsychiatric co-morbidities like depressive illness. Preclinical studies support this concept, including studies that have examined the effects of high-fat diet (HFD) on depressive-like behaviors. Although women are approximately two-fold more likely to develop depressive illness compared to men, most preclinical studies have focused on the effects of HFD in male rodents...

Curiosity is a powerful motivator of behaviour. Although there have been some studies pertaining to the application of curiosity in the realm of food, research examining the potential to influence consumer food waste behaviour through the induction of curiosity is lacking. This study conducted two onsite dining experiments to explore the role and mechanism of curiosity in reducing food waste in a real dining environment by utilising an information gap design in tableware to induce participants' curiosity. Experiment 1 investigated the differences in food waste between participants using bowls with an information gap design and those using bowls with no information gap (blank bowls)...

Tasting food is the first step toward diversifying eating habits and studies with children have typically focused on their sensory education and willingness to try new foods. While very little is known about how children taste foods during everyday mealtimes, EMCA (ethnomethodological and conversation analytic) research on adult tasting in naturalistic settings has demonstrated regular organisational patterns. This paper brings these two research areas together, using the insights of EMCA research on adult tasting to inform our understanding of how young children taste food during preschool lunches...

Evidence suggests higher hedonic hunger (preoccupation with/desire to consume food for pleasure) is associated with greater ultra-processed food (UPF) consumption in non-pregnant individuals with higher, but not lower, self-report impulsivity or delay discounting. The current study tested the association between hedonic hunger and UPF consumption, and the moderating effects of self-report impulsivity and delay discounting, during pregnancy. Individuals (N = 220) with body mass index (BMI)≥25 completed the Power of Food Scale, 24-h dietary recalls, and Barratt Impulsiveness Scale-Version 11 in early-mid pregnancy...

BACKGROUND: Emotional eating, or eating in response to negative emotions, is a commonly reported short-term emotion regulation strategy but has been shown to be ineffective in the long term. Most emotional eating interventions based on Acceptance and Commitment Therapy (ACT) have been delivered in the context of weight loss trials, highlighting a need for ACT-based emotional eating interventions in weight-neutral contexts. AIMS: This proof-of-concept study aimed to test the acceptability and efficacy potential of a brief virtual ACT workshop for emotional eating in a small sample of adults identifying as emotional eaters...

Multiple studies reveal that a requirement to stop a response to appetitive food stimuli causes devaluation of these stimuli. However, the mechanism underlying food devaluation after stopping is still under debate. The immediate-affect theory suggests that an increase in negative affect after stopping a response is the driving force for food devaluation. A competing value-updating theory presumes that food devaluation after stopping occurs through the need to align behavior with goals. The current study assessed how food devaluation after response inhibition is influenced by negative emotional reactivity and behavior-goal alignment on a trial-by-trial basis...

Sleep may influence appetite regulation through physiological and neurocognitive pathways. However, the association between sleep and appetite in childhood has been scarcely reported, particularly using a prospective design. We aimed to test associations between sleep duration at 7 years of age (y) and appetitive traits at both 7 and 10 y. Participants are from the population-based cohort Generation XXI (Porto, Portugal), at 7 (n=2437) and 10 y (n=1938) follow-ups. Data on sleep was gathered at 7 y and, considering bedtime and get-up time, total mean sleep duration was calculated and further categorized according to the 10th and 90th percentiles...

Food insecurity has been associated with negative short, medium, and long-term health consequences, which are more detrimental for children and adolescents. These effects may depend on the coping strategies developed to deal with food shortages. The present research aimed at exploring coping strategies in food insecure households with children and adolescents in Uruguay, incorporating sociological theoretical insights from Bourdieu. A qualitative approach based on individual semi-structured interviews was used...

The modern food-rich environment has contributed to the rise of unhealthy diets linked to noncommunicable diseases. Previous in-person research has found that the effect of social norms on food intake is greater when set by a perceived in-group member relative to an out-group member. Given recent increased social media use, we investigated whether this effect of group membership extends to food choices and to normative information presented remotely online. Participants (N = 179 female university students, 18-32 years) viewed a Facebook page pertaining to either their university (in-group) or a rival university (out-group)...

While considerable research exists on parent feeding practices for infants and toddlers, past research has not focused on children with feeding problems. The goal of this study was to identify parent feeding practices in a sample of infants (n = 178) and toddlers (n = 221) referred to a hospital-based feeding clinic and then examine how these parent feeding practices were correlated with specific feeding problems. Parents completed surveys to report child demographics, feeding problems, and use of 54 feeding practices...

Most instruments measuring nutrition literacy evaluate theoretical knowledge, not necessarily reflecting skills relevant to food choices. We aimed to develop and validate a photograph-based instrument to assess nutrition literacy (NUTLY) among adults in Portugal. NUTLY assesses the ability to distinguish foods with different nutritional profiles; from each of several combinations of three photographs (two foods with similar contents and one with higher content) participants are asked to identify the food with the highest energy/sodium content...

Eating competence (EatC) is an intra-individual approach to eating attitudes and behaviors associated with greater well-being. EatC research has not included persons with confirmed metabolic syndrome (MetS). Therefore, EatC of persons with MetS was explored to identify unique associations and inform implementation of MetS lifestyle interventions using baseline data from a multisite, randomized trial of a 2-year lifestyle intervention with MetS. EatC, measured with the Satter Eating Competence Inventory 2.0 (ecSI 2...

Food choice behavior plays a large role in achieving sustainability goals. Meat in particular has a negative environmental impact as compared with plant-based food - and is more frequently chosen in restaurant contexts. To increase plant-based meal choices in restaurants, we tested three nudges for menus that are likely to be implemented by restaurant owners: a hedonic label (e.g., artisanal vegetable burger), a chef's recommendation (specifying the vegetarian option as the chef's favorite), and a salience nudge (a box around the vegetarian option)...

Improving health and sustainability outcomes in WEIRD (Western, Educated, Industrial, Rich, Democratic) nations necessitates a reduction in red meat consumption. Seafood is often overlooked in achieving this goal. However, simply consuming more of familiar fish species places high stress on production of these species. For this reason, diversification of seafood consumption is also critical. Here the motives for seafood consumption (frequency and diversity) are investigated across two studies by adapting the 4Ns survey to the seafood category...
