Abstract
BACKGROUND Due to the growing risk of obesity and related diseases in the population of children, effective preventive measures are of great importance. Front-of-pack (FOP) nutrition labelling may contribute to health promotion by increasing consumer awareness on the nutritional qualities of packaged foods and purchasing decisions, and it may stimulate food providers to improve the composition of products. SUMMARY Appropriate labelling should enable customers to make healthy choices quickly and intuitively. Key Messages: The European Academy of Paediatrics and the European Childhood Obesity Group makes an appeal to European Union legislators to immediately introduce a mandatory, uniform, and interpretative FOP nutrition labelling system.

Measuring and Leveraging Motives and Values in Dietary Interventions.
Eustis, SJ, Turner-McGrievy, G, Adams, SA, Hébert, JR
Nutrients. 2021;(5)
Abstract
Why measure and leverage food motives and values? Every failure and every success in dietary change can be connected to motivation. Therefore, this research question naturally arises: How can food motives and values be measured and leveraged to improve diet outcomes from the individual to populations? There are four ways that food motives and values (FMVs) can assist researchers and health professionals. First, FMVs can help to create a personalized approach to dietary change. Second, FMVs can inform content for dietary interventions. Third, these FMV measures can be used in data analysis to elucidate differences in adherence and outcomes among participants. Fourth, public health nutrition messages can be tailored using information on FMVs. Each of these uses has the potential to further the literature and inform future efforts to improve diet. A central aim of our study is to provide specific examples and recommendations on how to measure and leverage FMVs. To do so, we reviewed 12 measures included in the literature citing the Food Choice Questionnaire by Steptoe, Pollard, and Wardle, which was identified as the earliest, highly cited article appearing under the search terms "food motives" AND "food values" AND "eating behavior" AND "measure". Specific details on how articles were selected from the citing literature are described in the Methods section. We also expound on our reasoning for including the Three-Factor Eating Questionnaire, which made for 13 measures in total. Our main finding is that each measure has strengths and shortcomings to consider in using FMVs to inform nutritional recommendations at different levels.

Nudging to get our food choices on a sustainable track.
Vandenbroele, J, Vermeir, I, Geuens, M, Slabbinck, H, Van Kerckhove, A
The Proceedings of the Nutrition Society. 2020;(1):133-146
Abstract
Food production is one of the major contributors to environmental damage. Adaptations in our food choices are needed to preserve resources for the needs of future generations. More sustainable consumption patterns have been encouraged by economic incentives, laws, education and communication campaigns. Nonetheless, consumers still find difficulties in trying to change their current food habits. This review takes a behavioural approach in encouraging sustainable food choices among consumers. From a nudging perspective, many behavioural changes can be encouraged in a non-obtrusive way by adapting the complex food environment in which consumers are operating. These interventions do not restrict consumers' choices but rather adapt the choice architecture wherein food decisions are made. Drawing on the literature from diverse theoretical perspectives, we provide an overview of the application of nudging for more sustainable food choices and highlight where more research is needed. More specifically, we discuss research that used nudging to engender cognitive impact (i.e. the use of labels or visibility enhancements), affective responses (i.e. sensorial and social influence cues) and behavioural effects (i.e. adjustments in convenience and product size). We conclude that this review only shows the tip of the iceberg of the research on nudging and sustainable consumption that is likely forthcoming in the next few years, following the successes of nudging applications in other domains. Nonetheless, each individual nudging intervention requires careful examination. Personal predispositions towards the environment should be considered when designing interventions, demonstrating the complementarity of nudging with education on sustainable consumption.

Food and beverage flavour pairing: A critical review of the literature.
Spence, C
Food research international (Ottawa, Ont.). 2020;:109124
Abstract
The recent explosion of interest in the topic of flavour pairing has been driven, at least in part, by the now-discredited food-pairing hypothesis, along with the emergence of the new field of computational gastronomy. Many chefs, sommeliers, mixologists, and drinks brands, not to mention a few food brands, have become increasingly interested in moving the discussions that they have with their consumers beyond the traditional focus solely on food and wine pairings. Here, two key approaches to pairing that might help to explain/justify those food and beverage combinations that the consumer is likely to appreciate are outlined. Historically-speaking, many conventional pairings emerged naturally from cultural/geographical matches, presumably internalized as semantic knowledge amongst consumers. In this review, such conventional pairings are framed as but one example of a cognitive/intellectual food-beverage strategy. The alternative approach to pairing that has become increasingly popular in recent years involves experts/commentators making recommendations based on the perceptual relationship, or interaction, between the component stimuli, be it one of perceived similarity, contrast, harmony, emergence, or modulation (either suppression or enhancement). Physicochemical accounts of pairing, based on the presence of shared flavour molecules (e.g., aromatic volatiles) in the to-be-combined flavours or ingredients, have also gained in popularity. Here, though, the latter approach is framed as an ultimately unsuccessful attempt to predict matches based on perceived similarity. This review summarizes the available evidence concerning food-beverage pairing and proposes a new dichotomy between intellectual/cognitive and perceptual pairing principles in the case of food-beverage matching.

Determinants of Sweetness Preference: A Scoping Review of Human Studies.
Venditti, C, Musa-Veloso, K, Lee, HY, Poon, T, Mak, A, Darch, M, Juana, J, Fronda, D, Noori, D, Pateman, E, et al
Nutrients. 2020;(3)
Abstract
Factors associated with sweetness preference are multi-faceted and incredibly complex. A scoping review was undertaken to identify determinants of sweetness preference in humans. Using an online search tool, ProQuest ™, a total of 99 publications were identified and subsequently grouped into the following categories of determinants: Age, dietary factors, reproductive hormonal factors, body weight status, heritable, weight loss, sound, personality, ethnicity and lifestyle, previous exposure, disease, and 'other' determinants. Methodologies amongst studies were heterogenous in nature (e.g., there was variability across studies in the sweetness concentrations tested, the number of different sweetness concentrations used to assess sweetness preference, and the methods utilized to measure sweetness preference), rendering interpretation of overall findings challenging; however, for certain determinants, the evidence appeared to support predictive capacity of greater sweetness preference, such as age during certain life-stages (i.e., young and old), being in a hungry versus satiated state, and heritable factors (e.g., similar sweetness preferences amongst family members). Recommendations for the design of future studies on sweetness preference determinants are provided herein, including an "investigator checklist" of criteria to consider.

Neural Mechanisms of Food Decision-Making in Children.
Ha, OR, Lim, SL, Bruce, AS
Current nutrition reports. 2020;(3):236-250
Abstract
PURPOSE OF REVIEW The goal of the current paper is to review the literature on the neural and behavioral factors involved in food decision-making in youth. RECENT FINDINGS Recent neuroimaging studies that employ passive viewing paradigms have found that exposure to food-related cues activate reward, motor planning, and attentional salience signals in children. Greater activations of reward signals and/or lower activations of control signals are associated with overeating and weight gain. Neuroimaging studies with decision-making paradigms have found the reward network in the brain activates during food choices, while control network activates less strongly. Findings suggest that exposure to food cues activates reward/valuation network, but activation of control network tends to be relatively weaker in children. Hedonic aspects of foods are predominantly considered in children's food choices, and their dietary self-control is not matured yet. The increased activation in reward network and the decreased activation in control network are associated with risk of developing obesity.

Front-of-package food labels: A narrative review.
Temple, NJ
Appetite. 2020;:104485
Abstract
Front-of-package (FOP) labels may help shoppers make healthier food choices. The objectives of this review are, first, to establish the effectiveness of different FOP labels at enabling shoppers to identify which foods are healthy and which are not healthy, and, second, to assess whether different FOP labels induce shoppers to buy healthier foods. Some labels are nutrient-specific, such as Multiple Traffic Lights (MTL) and Guideline Daily Amounts (GDA). These labels state the content per serving of energy and of several substances, most commonly saturated fat, sugar, and sodium (or salt). Warning labels are another type of nutrient-specific FOP label (e.g., for food high in added sugar). Summary labels, such as Nutri-Score and labels with stars, translate the components of the food into a single value that indicates how healthy it is. Studies on FOP labels lack consistency. The majority of such studies indicate that they help shoppers to distinguish between healthy and less healthy foods. The designs that appear to be most successful in this regard are MTL, warning labels, and Nutri-Score. Labels based on GDA or that included stars were much less successful. Many studies using a simulated shopping situation reported that shoppers exposed to FOP labels had an increased intent to purchase healthier foods. Warning labels were the most consistently successful FOP design followed by MTL, Nutri-Score, and labels that included stars, while GDA failed in almost every study. Very few studies have been carried out in real-world supermarkets; the findings indicate that FOP labels or shelf labels may achieve a small degree of success (<2.0%) at persuading shoppers to buy healthier foods. Those advocating for effective FOP labels must resist opposition from food corporations.

RYGB and flavor-consequence learning.
Asarian, L, Geary, N
Appetite. 2020;:104467
Abstract
Flavor-consequence learning refers to learned associations between flavor stimuli and post-oral consequences of food that affect food selection, amount eaten and affect. Forms of flavor-consequence learning include flavor aversions, flavor avoidance, conditioned satiety, expected satiety and appetition. Roux-en-Y gastric bypass surgery (RYGB) and other bariatric procedures alter gastrointestinal processing of food in a number of ways. Thus, it is plausible that these procedures alter post-oral unconditioned stimuli that support flavor-consequence learning, leading to altered food selection, amount eaten, and affect. Surprisingly, however, there is almost no research on the role of flavor-consequence learning in the effects of bariatric surgery on appetite. This issue urgently warrants investigation.

Demystifying wine tasting: Cognitive psychology's contribution.
Parr, WV
Food research international (Ottawa, Ont.). 2019;:230-233
Abstract
Over recent decades, cognitive psychology has made a significant contribution to our understanding of wine-tasting phenomena. At the most fundamental level the discipline's contribution has made us aware that even an apparently 'simple' judgment, such as noting that a wine's odour reflects over-ripe fruit, involves not just our nose but sophisticated cognitive processing. With its information-processing model of how people interact with their surrounding world, and its methodologies and theories regarding how we perceive, conceptualise, remember, image, make judgments, and communicate our experiences, cognitive psychology has markedly advanced our understanding of wine tasting and wine tasters. This review highlights notable wine sensory research outcomes that make evident the importance of a taster's cognitive processes in their wine analysis and appreciation. These include data providing evidence for colour-flavour perceptual bias, prototypical thinking, knowledge-based wine judgments, the close links between olfactory memory, autobiographical memory and emotion, and the notion of wine expertise. Further, it will be argued that such data demonstrate how a consensus model, still dominant in much wine sensory analysis, is limited at best and inappropriate for sensory analysis of complex products such as wine in many contexts. Critical to this argument is appreciating that differences amongst tasters, reflecting each individual's physiology, experience and knowledge, are valid data in themselves rather than 'error in the machine' as they were conceptualised within traditional consensus models of sensory analysis. The article terminates with reference to a promise for even greater understanding of wine tasting phenomena that the future offers by links between cognitive psychology's behavioural data and recent technological advances in neuropsychology and neurophysiology (e.g., cerebral imaging techniques).

The credibility of the effects of functional food products and consumers' willingness to purchase/willingness to pay- review.
Plasek, B, Temesi, Á
Appetite. 2019;:104398
Abstract
The credibility aspect of any food product is important in order to find and keep consumers, which is especially true for functional foods. Market success of these products depends mostly on the credibility of their beneficial effects on health. The aim of this literature review was to identify aspects that make the positive health effect of a functional product credible for consumers. Based on the established connection between purchase intention and credibility, articles have been collected, summarized and restructured. Research papers have been analyzed through a two-step selection process. From 1724 studies, 54 were selected to discuss the above mentioned topics. It has been found that most of the studies focus on the credibility of health claims, while those exploring the connection between different kinds of product attributes and the credibility aspect of functional food products are rare. It is believed that other features can significantly affect this aspect and it is strategically important to know these factors influencing credibility. The literature analysis showed that willingness to purchase functional products is influenced by sensory and non-sensory-characteristics of the product, while willingness to pay is affected for example by consumers' trust in functional foods. On the issue of what influences the credibility of the health benefits of functional products, ambiguous information was found. While one of the most important factors influencing acceptance of functional foods is credibility of information, other researchers' results show no direct significant relationship between credibility of health claims and willingness to purchase. Credibility of health effect is also influenced by the base product and the carrier ingredient, the source of information, the product design and cultural roots of a country.
