Impact of sweetness on children's eating behaviour: the roles of taste and calories

2014

International audience; The sweet taste is innately liked as shown in newborns. This attraction, confirmed in older children1, is interpreted in relation to the advantage conferred by the consumption of the energy of sugars. However, the impact of the taste and of the calories from sugar needs further clarification. Two studies will be presented, aimed at understanding the role of taste and calories from sugar in children from different age groups. The first study looked at flavor-flavor learning by pairing the taste of a vegetable with the sweet taste in 6-month-old infants. It shows that adding sweet taste is associated to a higher consumption of the vegetable in the sweet version but not…

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…

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…

Les comportements alimentaires. Quels en sont les déterminants ? Quelles actions pour les faire évoluer vers une meilleure adéquation avec les recomm…

2012

International audience; Although public policies have for many years spearheaded information campaigns about how eating affects health, rising obesity rates show that the expected effects have yet to be achieved. Why consumers do not practically comply with nutritional recommendations? This question lead the ministry in charge of Agriculture, Food and Fisheries to require in 2010 an updated state of knowledge for peer-reviewed literature and to commission INRA to undertake a collective scientific expertise on dietary behaviours. The aim was to investigate the multiple determinants of behaviours and how behaviours form and change in individuals according to social class and age, but also col…

Spatial fuzzy consumer's behavior : a multidimensional analysis

1983

This paper is devoted to a multidimensional analysis of the consumer'sbehavior when the decisionmaker is acting in a fuzzy space and pointingout an imprecise attitude. At first, the process of decisionmaking is described with the help of three relationships between the set of goods which are supplied in several points, the set of their characteristics and the set of consumer's a priori possible behaviors. All these relations are fuzzy. The model applies the theory of fuzzy relations equations. Then, the stages of the decision process are analyzed. Often fuzzy comportemental relations are like "black boxes". The mathematical solution of the model indicates in which conditions their valuation…

CO2 EFFECTS ON SPAWNING RATES OF A MEDITERRANEAN NESTING WRASSE

2014

Some aspects of the reproductive behaviour of the ocellated wrasse Symphodus ocellatus (Forsskål 1775) were investigated in wild conditions along a pCO2 gradient. Our results show no differences in the number of females, sneakers and satellite males involved in the spawning phase under two pCO2 conditions. However, the spawning rate of nesting males was negatively affected in high pCO2, whilst exerted a normal reproductive pattern in ambient pCO2.
