Observational techniques: applications to the study of children’s eating behavior
2010
Les réunions ESN sont réservées aux membres.; Human behavior can be observed in many different ways, depending on the question asked. One may prefer to observe than to ask direct question, to avoid interferences with cognitive processes; or because individuals may not directly answer a question. This is specially the case for infants and young children, who can not express themselves verbally in a reliable way. We will describe in particular how to study infants and children sensory perceptions (taste and olfaction in particular) and eating behavior, focusing in particular on the analysis of facial expressions.

High fat diet rapidly induces brain-plasticity-related transcriptomic signature in hypothalamus: role in energy homeostasis
2010
Poster board E12 (1 page) ; Session 203 - Food intake regulation 3 - Abstract n° 203.1 - Publication ref.: FENS Abstr., vol.5, 203.1, 2010; International audience; We have investigated the early events that are induced by a hypercaloric hyperlipidic diet in mice. The high fat diet rapidly induced metabolic imbalance, as soon as the first day, which is characterized. by a large increase in energy intake and several others metabolic alterations such as. hypercholesterolemia, and glucose intolerance. However, the diet-induced metabolic imbalance was. fully reversed after a week, suggesting that a physiological adaptive response has been then induced,. probably in order to counteract the delete…
Effet de l'âge sur les consommations alimentaires et les raisons de non-consommation : résultats d'une enquête menée auprès de 32 000 adultes âgés de…
2017
National audience; Introduction et but de l'étude : S'il existe un certain nombre d'études ayant décrit les consommations alimentaires au sein de la population française dans différentes classes d'âge (eg, étude INCA3, 2017, pour la plus récente), très peu se sont intéressées aux raisons de non-consommation de tel ou tel type d'aliment, et notamment à l'évolution de ces raisons de non-consommation au cours de l'avancée en âge. Matériel et méthodes : 32 696 volontaires enrôlés dans la cohorte française NutriNet-Santé (20-80 ans ; 76% de femmes) ont évalué leur fréquence de consommation de 21 catégories d'aliments (eg, viande ; poisson & fruits de mer ; légumes crus…). En cas de non-consommat…

Amélioration des repas et variété : Quel impact sur la prise alimentaire et le plaisir des seniors dépendants ?
2013
National audience; Introduction et but de l'étude: S’alimenter est un acte indispensable à la vie qui fait intervenir l’ensemble de nos fonctions sensorielles. Au-delà de ces fonctions, nous apprécions, aussi, davantage un repas lorsque le plat est à notre goût ou lorsqu’il est présenté avec soin et avec de la variété. Au cours de l’avancée en âge, pathologies et dépendance constituent des facteurs de dénutrition importants (HAS 2007) et augmentent le risque de placement en institution. En collectivité, le libre choix disparait ce qui peut réduire sensiblement le plaisir des repas. L’objectif du travail était d’identifier des leviers pour lutter contre la problématique nutritionnelle du suj…
Alcoholic beverages, obesity, physical activity and other nutritional factors, and cancer risk: A review of the evidence
2016
International audience; Purpose: Prevention is a priority in the fight against cancers, especially nutritional prevention. To update the levels of evidence of relationships between 10 nutritional factors and cancer risk, the scientific literature published from 2006 to 2014 was reviewed by an expert group.Methods: Data from 133 meta-analyses, pooled analyses or intervention trials were examined. Nearly 150 relationships between nutritional factors and cancer at various sites were evaluated.Results: According to the evidence graded as convincing or probable, these factors were divided in two groups. Factors which increase the risk of cancer are alcoholic beverages, overweight and obesity, re…
Role of the non-infective stage of the acanthocephalan parasite Pomphorhychus laevis on the behavioural manipulation of its amphipod intermediate host
2012
In trophically-transmitted parasites, exploitation strategies of the intermediate host have been selected, in a way increasing parasites transmission probabilities to their definitive host. Particularly, numerous parasites are able to alter their intermediate host behaviour, a phenomenon called ‘behavioural manipulation’. This manipulation only occurs when the parasite developmental stage (or larval stage) is infective for the definitive host. Before reaching this stage, the development of parasite larvae is not sufficiently advanced to allow establishment in the definitive host (this stage is thus called ‘non-infective’). Early transmission of a non-infective stage therefore implies parasi…
Hedonic sensations implicated in the control of human food intake : alimentary alliesthesia and sensory-specific satiety
2011
The control of food intake is a complex and multifactorial process controlled by the CNS. It is implicated in the regulation of body weight and the supply of energy substrates, as well as the supply of a panoply of nutrients to cover the specific needs of the organism. Among all the factors involved, hedonic sensations play an important role in guiding food selection and limitation of intake. The theoretical section of this thesis takes into account the physio-anatomical aspects of the control of food intake, in particular sensory pleasure and its evaluation, within the framework of the three principal hedonic phenomena: Conditioned Satiety (CS), Alimentary alliesthesia (AA) and sensory-spe…
