Portion size selection in children: Effect of sensory imagery for snacks varying in energy density
2020
Food sensory imagery - creating a vivid mental image of the sensory experience of eating - can lead to the selection of smaller portions because it serves as a reminder that eating enjoyment does not necessarily increase with portion size. The evidence is mostly limited to adults and to energy-dense foods for which it is particularly difficult to predict the satiating effects of consumption quantity. The objective was to study how food sensory imagery influences portion size selection of foods varying in energy density (brownie and applesauce) by 7- to 11-year-old children. During after-school time, 171 children were randomized into two conditions. Children in the food sensory imagery condi…
Adolescent sugar-sweetened beverage consumption: An extended Health Action Process Approach.
2019
Abstract Objective Consumption of excess added sugar in the form of sugar-sweetened beverages (SSBs) contributes to a wide range of health concerns in adolescents. Identification of modifiable determinants of SSB consumption based on behavioral theory may inform development of interventions aimed at reducing SSB consumption. The aim of the current study was to test the efficacy of an extended version of the Health Action Process Approach to predict adolescent SSB consumption. Methods Using a prospective design, adolescent students (N = 450) self-reported their outcome expectancies, perceived behavioral control, intentions, habit, action, maintenance, and recovery self-efficacy, action and c…
Associations between food consumption patterns and saliva composition: Specificities of eating difficulties children
2017
Identifying objective markers of dietwould be beneficial to research fields such as nutritional epidemiology. As a preliminary study on the validity of using saliva for this purpose, and in order to explore the relationship between saliva and diet, we focused on clearly contrasted groups of children: children with eating difficulties (ED) receiving at least 50% of their energy intake through artificial nutrition vs healthy controls (C). Saliva of ED and C children was analyzed by various methods (targeted biochemical analyses, 2-D electrophoresis coupled to MS, 1H NMR) and their diet was characterized using food frequency questionnaires, considering 148 food items grouped into 13 categories…
Is harsh caregiving effective in toddlers with low inhibitory control? An experimental study in the food domain
2016
International audience; The aim of our study is to evaluate the validity of the "Caregiving x Temperament Paradigm" in the food domain. In this study, two prototypes of caregiving,control have been contrasted: Harsh (forceful measures to curve the child's behavior) versus Gentle control (supportive measures to direct the child's behavior). In food domain, the most effective control to help a child to overcome initial dislike is repeated exposure. Our first objective was to test whether the repeated exposure displayed in a gentle context has a more benefical effect on dislike shifting than the one displayed in a harsh context. Our second objective was to assess whether this effect was modera…
Study of Consumer Preferences in Regard to the Blonde Orange Cv. Washington Navel “Arancia Di Ribera PDO”
2016
Consumers’ attitude and preferences in regard to food ingre- dients, country of origin, social corporate responsibility toward the environment, and work conditions have changed over the last 10 years. Consumers are getting more educated and there- fore more sensitive around cultivation practices in agriculture and food processing, which increases concerns in regard to production practices in agriculture. Several studies have been conducted on consumers’ preferences about quality food, but not with regard to blonde oranges cv. Washington Navel culti- vated in southern Italy. This quality fruit is a niche product that achieved the Protected Designation of Origin (PDO) certifica- tion for high…

The habitual nature of food purchases at the supermarket: Implications for policy making
2020
Abstract Supermarkets have become the most important provider of food products worldwide. However, empirical evidence about how consumers make their food purchase decisions in this environment is still scarce. The present field study aimed to: i) explore how people make their in-store food purchases, and ii) identify the information they search for when making those purchases. Consumers (n = 144) were intercepted when entering the facilities of three supermarkets in two Uruguayan cities. They were asked to wear a mobile eye-tracker while they made their purchases as they normally do. The great majority of the consumers bought at least one food product or beverage (92%) and, on average, exam…

Towards more sustainable food systems. Addressing food waste at school canteens
2018
Food Waste is a global significant issue for ethical, environmental and economic reasons, while its management is difficult due to its frequent low visibility. Individual choices and preferences are closely related to the generation of food waste although likely to be modified through education and awareness campaigns. In particular, school canteens are big generators of food waste and, at the same time, provide a great opportunity to improve habits regarding nutrition and education on sustainability, thus impacting the future of the food system. The end purpose of this research is identifying the causes of food waste and unveiling best practices towards its reduction. To achieve this goal,…
ERK1/2 activation in human taste bud cells regulates fatty acid signaling and gustatory perception of fat in mice and humans
2016
Obesity is a major public health problem. An in-depth knowledge of the molecular mechanisms of oro-sensory detection of dietary lipids may help fight it. Humans and rodents can detect fatty acids via lipido-receptors, such as CD36 and GPR120. We studied the implication of the MAPK pathways, in particular, ERK1/2, in the gustatory detection of fatty acids. Linoleic acid, a dietary fatty acid, induced via CD36 the phosphorylation of MEK1/2-ERK1/2-ETS-like transcription factor-1 cascade, which requires Fyn-Src kinase and lipid rafts in human taste bud cells (TBCs). ERK1/2 cascade was activated by Ca2+ signaling via opening of the calcium-homeostasis modulator-1 (CALHM1) channel. Furthermore, f…
