Détection orosensorielle des lipides alimentaires chez la souris : mécanismes impliqués et altérations au cours de l'obésité

2015

Dietary lipids are detected by the gustatory system in rodents and humans. Two candidate lipid-receptors are found in taste buds: CD36, which is involved in the fat taste as shown by studies conducted in our laboratory, and GPR120. Our results show that GPR120 is not directly involved in the gustatory detection of lipids in mice, but could rather be involved in the modulation of the sensitivity for fat. When this gustatory system works properly, food choices can meet the organism’s energy needs. Besides, the pleasure brought by the consumption of palatable foods is satisfied. However, obese people often overconsume energy-dense food. In the central nervous system, perturbations of the rewar…

Xenohormones and oral homeostasis : impact on taste preferences and salivary glands

2012

Oral homeostasis strongly influences taste perceptions. It depends on a healthy oral epithelium and salivary gland secretions, which are both regulated by sex hormones. The aim of this thesis was to identify the effect of an oral exposure to Bisphenol A, a food packaging and dental sealer component, and of a soy-diet containing phytoestrogens on oral homeostasisTwo experiments were conducted in adult rats: a dose-response study of BPA (5μg 12.5 mg / kj / day), and a study about the impact of a soy-diet on the BPA disrupting effects. By using gustation choice tests, and histological and qPCR-TR molecular approach, we identify for the first time an action of BPA on dry mouth. We found that BP…

Formulation, caractérisation et validation d'un pain "satiétogène"

2011

This PhD project was aimed at the formulation, the characterization and the validation of one bread, processed from flour selected to increase the satiety effects on humans. For the last several decades, the prevalence of overweight and obesity around the world has been increasing. The risks of obesity are responsible for a stagnation of life expectancy in some industrialized countries. In order to stop this pandemic phenomenon, dietary fibre appears to have beneficial effects on the decrease in feeling hunger, caloric intake and body weight of obese participants. The first goal of this work was to process two fibre-enriched breads: one of them was a “whole grain” bread (PF1), and the secon…

Déterminants précoces du comportement alimentaire

2010

International audience; Compte tenu des liens entre l'alimentation et certaines pathologies et sachant qu'il est difficile de changer les habitudes alimentaires de l'adulte, de l'adolescent et même de l'enfant, il semble souhaitable que l'enfant acquiert le plus tôt possible des habitudes alimentaires les plus en accord avec les recommandations nutritionnelles. Il est donc important de mieux connaître le rôle des expériences précoces dans la mise en place du comportement alimentaire.(...)

Manger confiné : quel impact sur nos habitudes alimentaires ?

2020

Il y a peu de temps, la population française vivait une période inédite : neuf semaines confinées à la maison. Des chercheurs du CSGA se sont intéressées à l'impact du confinement sur les habitudes alimentaires en déployant une vaste enquête auprès de 500 parents d'enfants de 3-11 ans.

"Boire un verre dans un bar...!" - Modulation de l'expérience d'un produit par le contexte. Apport de l'immersion à l'étude des influences contextuel…

2013

The overall aim of the present thesis is to study contextual influences on food behaviour (including variables coming from the environment and from the consumer). To this purpose, an immersive method using a space with physical elements was used, in order to evoke a realistic situation within a laboratory setting. Here, the method consisted in designing an immersive bar evoking the situation of “having a drink in a bar”. Two variants of the bar were created and five studies were implemented in these spaces to study how context influences food choices and evaluation. Our approach consisted in taking the product as central in the link between the consumer and the environment and not as a cont…

Développement précoce du comportement et des préférences alimentaires

2014

Manger est essentiel pour la survie, et nous naissons équipés pour absorber des nutriments à partir des apports alimentaires. Cependant, l'alimentation ne se résume pas à cet aspect. Quoi, comment, quand, combien manger sont autant de questions qui renvoient à d'autres aspects du comportement alimentaire, auxquelles il nous faut répondre quotidiennement. Ces autres aspects du comportement alimentaire sont appris, essentiellement durant les premières années de vie [1]. Ainsi, nous avons montré que les comportements alimentaires acquis à l'âge de 2 à 3 ans étaient prédictifs des mêmes comportements observés chez le jeune adulte [2,3]. Pour cette raison, il est fondamental de savoir quand et c…
