This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meals in our current environment are characterized by a wide variety of energy dense foods that are served in large portions. Numerous studies have shown that more is consumed as portion size is increased, and this portion size effect has been implicated in the development of obesity. It has been suggested that this portion size effect may be facilitated by sensory-specific satiety (SSS), the relative hedonic decline of a food as it is consumed leading to meal termination. Factors such as variety and oral processing behaviors that influence SSS therefore have the potential to moderate the effects of portion size. Understanding how these SSS-related factors relate to the effect of portion size on intake can increase our understanding of the mechanisms underpinning this portion size effect, and could help to identify strategies to attenuate overconsumption from large portions. Therefore, in studies 1 and 2, we investigated whether oral processing behaviors such as eating rate, bite size and switching between bites and sips moderated the portion size effect. We also explored how sensory-specific satiety was affected by oral processing behaviors and larger portions. In a randomized crossover design, 44 adults aged 18-68 y (66% women; 46% with overweight and obesity) ate lunch in the laboratory once a week for 4 weeks. The meal consisted of pasta that was varied in portion size (400, 500, 600, or 700 g) and 700 g of water. Meals were video-recorded to assess bite count, sip count, and meal duration, which were used to calculate mean eating rate (g/min) and mean bite size (g/bite) and the number of switches between bites and sips. At each meal participants also completed an assessment of SSS. The results showed that as larger portions were served, meal intake increased in a curvilinear manner (p0.0001). Oral processing behaviors did not moderate the portion size effect but were related to intake across all portions; faster eating rate and larger bite size (both p0.0001), and more frequent switching between bites and sips (p0.004) were associated with greater consumption at all meals. SSS was not influenced by any of the oral processing behaviors or by portion size (all p0.10), suggesting that these behaviors allowed greater food intake for a given hedonic decline. In summary, the portion size effect was not moderated by oral processing behaviors, but the effects of faster eating rates, larger bite sizes, and more frequent switching between bites and sips at meals combined with large portions to increase food intake. In Study 3, we investigated how increases in food variety and portion size can combine to promote consumption, and how their effects differ depending on meal structure (e.g., foods served together vs. sequentially over multiple courses). In 2 randomized crossover experiments, women ate a lunch once a week consisting of either 3 main dishes or only their favorite of the dishes (shrimp teriyaki, chicken alfredo, southwestern rice; all 1.3 kcal/g). In Experiment 1 (n=42), the dishes were served simultaneously and in Experiment 2 (n=49), the dishes were served sequentially over 3 courses. Across 4 weeks, meals varied in 2 properties: variety (low: 3 bowls of the favorite vs. high: 3 bowls, each with one of the dishes) and meal portion size (small: 450 g vs. large: 600 g). At each meal, sensory-specific satiety was measured as the relative change in the pleasantness of the taste and desire to eat the favorite dish from before to after consumption. In Experiment 1 variety and portion size did not interact (p=0.72) but both independently increased food intake; 15±7 g more was consumed at meals with high variety compared to low, and 57 ±7 g more was consumed from large portions compared to small (both p

Download or read book Flavor Satiety and Food Intake written by Beverly Tepper and published by John Wiley & Sons. This book was released on 2017-06-12 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book provides a comprehensive review of the latest science on a key aspect of appetite control. It brings together contributions by leading researchers worldwide who approach this complex, multifaceted issue from a variety of differing perspectives, including those of food science, psychology, nutrition, and medicine, among others. It is well known that products that require greater oral processing tend to be more sating. At the same time, the orosensory exposure hypothesis holds that flavor and texture in the mouth are critical in determining meal-size. They may act as key predictors of nutritional benefits and so promote better processing of foods. These two related ideas are at the forefront of current thinking on flavor-satiety interactions. Yet, until Flavor, Satiety and Food Intake no book has offered an integrated treatment of both concepts. The only single-source reference of its kind, it brings health professionals, product developers, and students up to speed on the latest thinking and practices in this fascinating and important area of research. Provides readers with a unique and timely summary of critical recent developments in research on the impact of flavor on satiety Explores a topic of central importance both for food professionals seeking to develop healthier products and health professionals concerned with obesity and over-eating Brings together relevant topics from the fields of food science, psychology, nutrition and medicine Flavor, Satiety and Food Intake provides product developers with valuable information on how to integrate sensory evaluation with product formulation and marketing. It will also serve as a useful resource for health professionals and is a must-read for students of a range of disciplines in which appetite and satiety are studied.

Download or read book Sensory specific Satiety and Repeated Exposure to Novel Snack Foods written by Sarah Louise Robins-Hobden and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sensory-specific satiety (SSS) is a significantly greater pleasantness decline for a consumed (Eaten) food, than foods that are tasted but not consumed (Uneaten). SSS occurs during consumption, reaches optimal magnitude immediately afterwards, and returns to baseline within two to three hours. The phenomenon is dependent on the sensory properties, rather than the energy or macronutrient content of the food. To the extent that an Uneaten food shares similar sensory properties with the Eaten food, the Uneaten food may be subject to pleasantness decline: a transfer effect. Repeated exposure to a food stimulus may alter liking in the long-term, through mere exposure, monotony, and dietary learning paradigms resulting in an association between the novel target food and either a known food stimulus, or a consequence of consumption. Novel foods are more susceptible to these effects than familiar foods, for which learned associations may have already formed. Repeated consumption alone does not modulate SSS, but to date such studies have not tested novel foods. Through six experiments this research explores the influences of long-term pleasantness changes of novel foods and the number and type of Uneaten foods present during SSS testing, on the magnitude of SSS for snack foods. While no evidence of mere exposure or dietary learning was found, and in some instances experiments failed to induce SSS, these negative results are likely due to methodological, and sometimes procedural issues in the design and conduct of experimental testing. Findings revealed SSS to be vulnerable to a number of procedural and methodological factors, such as: portion size; baseline novelty and pleasantness ratings; hunger; perceived ambiguity of measurement scales; and expectations raised by the type and number of Uneaten foods present during testing.

Download or read book Food Texturology Measurement and Perception of Food Textural Properties written by Andrew Rosenthal and published by Springer Nature. This book was released on 2024-01-21 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept behind this book is to take a holistic view of food texture, starting with the determination of food texture, its perception in the mouth, and its measurement by both sensory and instrumental methods, and to examine the relation between them. The book has been divided into four sections: Fundamentals, Sensory and Human Interactions, Instrumental Analysis, and Food Products. Essentially we cover the techniques used for measuring food texture, and then apply them to the different product groups. Readers of the first edition will notice the title has changed, with the adoption of the term texturology. In the long history of food texture research, texturology has been occasionally used in literature. The term texturology has not been widely accepted by texture researchers (texturologists) because of their concern over whether the theories and techniques are broad and strong enough to support texture research as a scientific discipline. During the 24 years since the publication of the first edition, the editors have observed vast developments in theories as well as the assessment methodology of food texture (both sensory and instrumental) and these have shaped our understanding. This second edition brings the science up to date by introducing topics not previously covered (e.g. psychophysics, tribology, oral processing, texture maps and special foods for dysphagia patients). It includes an exposé of the instruments to measure food texture, and also considers techniques for measuring consumer perception of food texture (in addition to the sensory properties). Additionally, it amends omissions from the first edition such as dairy products; fish; bakery products; and, sugar confectionery, asproduct groups. All in all it is expanded and updated in its coverage of food texturology, as a coherent scientific discipline.

Download or read book Emotion Measurement written by Herbert L. Meiselman and published by Woodhead Publishing. This book was released on 2021-04-09 with total page 1046 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emotion Measurement, Second Edition highlights key elements of emotions that should be considered in the measurement of emotions in both academic and commercial environments. This edition begins with an updated review of basic studies of emotion, including the theory, physiology, and psychology of emotions, as these are the foundational studies which food scientists as well as product developers and marketing professionals need to be aware of. The second section highlights methods for studying emotions, and reviews the different approaches to emotion measurement: questionnaire self-report, behavioral, and physiological. This section explores the merits of intrinsic versus extrinsic measures of emotion. Some new measurement approaches have emerged since the first edition of this book. The book then presents practical applications, with chapters on emotion research in food and beverage, as well as in a range of products and clinical settings. The experience in testing product emotions has increased since the first edition when product emotion research was newer. Finally, Emotion Measurement, Second Edition provides coverage of cross-cultural research on emotions. This is critical because much of the newer commercial research is aimed at markets around the world, requiring methods that work in many cultures. And the universality of emotions has been a topic of research for decades. Taking both an academic and applied approach, Emotion Measurement, Second Edition will be an invaluable reference for those conducting basic academic research on emotions and for sensory and consumer scientists, and the product developers and marketing professionals they work alongside. Reviews both the academic and the applied strands of emotion measurement research Focuses on cross-cultural studies of emotions, which is currently lacking from most of the literature in the field Highlights methods for studying emotions in both basic and applied studies

Download or read book Multisensory Imagery written by Simon Lacey and published by Springer Science & Business Media. This book was released on 2013-01-19 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is a pear sweeter than a peach? Which of Mona Lisa’s hands is crossed over the other? What would the Moonlight Sonata sound like played by a brass band? Although these are questions that appeal to mental imagery in a variety of sensory modalities, mental imagery research has been dominated by visual imagery. With the emergence of a well-established multisensory research community, however, it is time to look at mental imagery in a wider sensory context. Part I of this book provides overviews of unisensory imagery in each sensory modality, including motor imagery, together with discussions of multisensory and cross-modal interactions, synesthesia, imagery in the blind and following brain damage, and methodological considerations. Part II reviews the application of mental imagery research in a range of settings including individual differences, skilled performance such as sports and surgical training, psychopathology and therapy, through to stroke rehabilitation. This combination of comprehensive coverage of the senses with reviews from both theoretical and applied perspectives not only complements the growing multisensory literature but also responds to recent calls for translational research in the multisensory field.

Download or read book Is Food Marketing Making Us Fat written by Pierre Chandon and published by . This book was released on 2011 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is Food Marketing Making Us Fat? reviews the literature in marketing, nutrition, psychology, economics and related disciplines that investigate the link between marketing activity, food intake and obesity, with a particular emphasis on the effects of marketing on overeating. The authors bring together streams of research which have so far been largely disconnected. To limit the scope of the review, this monograph focuses on the direct effects of marketing activity under the direct control of food marketers and on consumption volume because of its direct impact on food/energy intake. It also reviews studies on food choice to the extent that it obviously impacts energy intake but exclude studies of the effects of marketing on energy expenditure.

Download or read book The Interdisciplinary Science of Consumption written by Stephanie D. Preston and published by MIT Press. This book was released on 2014-08 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scholars from psychology, neuroscience, economics, animal behavior, and evolution describe the latest research on the causes and consequences of overconsumption. Our drive to consume—our desire for food, clothing, smart phones, and megahomes—evolved from our ancestors' drive to survive. But the psychological and neural processes that originally evolved to guide mammals toward resources that are necessary but scarce may mislead us in modern conditions of material abundance. Such phenomena as obesity, financial bubbles, hoarding, and shopping sprees suggest a mismatch between our instinct to consume and our current environment. This volume brings together research from psychology, neuroscience, economics, marketing, animal behavior, and evolution to explore the causes and consequences of consumption. Contributors consider such topics as how animal food-storing informs human consumption; the downside of evolved “fast and frugal” rules for eating; how future discounting and the draw toward immediate rewards influence food consumption, addiction, and our ability to save; overconsumption as social display; and the policy implications of consumption science. Taken together, the chapters make the case for an emerging interdisciplinary science of consumption that reflects commonalities across species, domains, and fields of inquiry. By carefully comparing mechanisms that underlie seemingly disparate outcomes, we can achieve a unified understanding of consumption that could benefit both science and society.

Available in PDF, EPUB and Kindle. Book excerpt: A Publishers Weekly Best Book of the Year From an obesity and neuroscience researcher with a knack for engaging, humorous storytelling, The Hungry Brain uses cutting-edge science to answer the questions: why do we overeat, and what can we do about it? No one wants to overeat. And certainly no one wants to overeat for years, become overweight, and end up with a high risk of diabetes or heart disease--yet two thirds of Americans do precisely that. Even though we know better, we often eat too much. Why does our behavior betray our own intentions to be lean and healthy? The problem, argues obesity and neuroscience researcher Stephan J. Guyenet, is not necessarily a lack of willpower or an incorrect understanding of what to eat. Rather, our appetites and food choices are led astray by ancient, instinctive brain circuits that play by the rules of a survival game that no longer exists. And these circuits don’t care about how you look in a bathing suit next summer. To make the case, The Hungry Brain takes readers on an eye-opening journey through cutting-edge neuroscience that has never before been available to a general audience. The Hungry Brain delivers profound insights into why the brain undermines our weight goals and transforms these insights into practical guidelines for eating well and staying slim. Along the way, it explores how the human brain works, revealing how this mysterious organ makes us who we are.

Download or read book Obese Humans and Rats Psychology Revivals written by Stanley Schacter and published by Psychology Press. This book was released on 2014-10-14 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1974, this volume examines the behavioural similarities of obese humans and animals whose so-called feeding centre (the ventro-medial hypothalamic nuclei) has been lesioned. Both the obese human and the VMH-lesioned animal seem to share a hyposensitivity to the internal (physiological) cues to eating and hypersensitivity to external cues associated with food. Beginning with a review, these obese animals and the human obese are compared point by point on experimental results reported in the literature. Then, new findings are presented that specifically tested humans for relationships that are well-established for lesioned animals. Next, a theoretical framework integrates the human and animal data to postulate that the relationship of cue prominence and probability of response is stronger for the obese than for normal. The causes for this, and the extension of the basis for the obese’s eating behaviour to other areas, are discussed in light of further experiments that will make this invaluable reading for all concerned with the history of obesity and the issues of regulatory behaviour.
