Salivary Composition Is Associated with Liking and Usual Nutrient Intake
2015
Salivary flow and composition have an impact on flavor perception. However, very few studies have explored the relationship between saliva, individual liking and usual dietary intake. The aim of our study was to evaluate the association of salivary flow and composition with both a liking for fat, saltiness and sweetness and the usual nutrient intake in an adult French population. Liking for fat, saltiness, and sweetness were inferred from liking scores obtained during hedonic tests on 32 food products among 282 French adults participating in the Nutrinet- Santé Study. Before assessing liking, resting saliva was collected. Standard biochemical analyses were performed to assess specific compo…
Macular pigment change during eye ageing : analysis from population based study, Montrachet study
2018
Given the limits of the literature on the environmental nutritional impact in ocular aging witch is partially due to the lack of data in general population notably in French elderly, first, we were interested in the relationships of diet, plasma xanthophylls and macular pigment optical density as well as its spatial distribution and second of plasma fatty acids and dry eye disease signs in the 1153 Montrachet study participants.Firstly, we reported the high consumption of squash, the high plasma lutein and zeaxanthin levels and also the high plasma lutein level, the high macular pigment optical density level in nonsmokers subjects. In addition, the macular pigment values we provided in the …
Bien et bon à manger. Penser notre alimentation du quotidien à l'institution
2018
International audience; Cet ouvrage a pour volonté de penser notre rapport actuel à l’alimentation qui se trouve aujourd’hui en prise avec de nombreux discours portés par différents acteurs du monde social : institutions de santé publique, industries agroalimentaires, médecins, experts médiatiques, journalistes… Si on observe depuis plusieurs années un rapport à notre alimentation qui tend à se médicaliser, les dimensions de plaisir et de convivialité restent pourtant prédominantes. Si le bien manger tend souvent à limiter notre alimentation aux dimensions nutritionnelles, le bon à manger propose une autre lecture de nos comportements alimentaires. En effet, il lie le plaisir et le sain car…
Red currant and black current, new cultivated fruits in late medieval and early modern Europe: Historic and archaeobotanical evidence
2016
International audience; Red and black currants are cultivated as garden shrubs in Germany, Holland, Denmark and the eastern neighbours of the Baltic since 500-600 years (Karg 2007, Wiethold 2007). Older medieval archaeobotanical finds in central and northern Europe are doubtful concerning dating and/or determination. Some of them may represent some rare collections from the wild. The origin of cultivation is estimated in northern France or Belgium (Killermann, cited by Hegi 1961 : 53), but detailed modern research on this question is still lacking. Nevertheless, the centre of biodiversity of Ribes rubrum L. and Ribes nigrum L. is clearly located in northern and north-western Europe. The fru…
An odor timer in milk? Synchrony in the odor of milk effluvium and neonatal chemosensation in the mouse.
2012
International audience; Mammalian newborns exhibit avid responsiveness to odor compounds emanating from conspecific milk. Milk is however developmentally heterogeneous in composition as a function of both evolved constraints and offspring demand. The present study aimed to verify whether milk odor attractivity for neonates is equally distributed along lactation in Mus musculus (Balb-c strain). Therefore, we exposed pups varying in age to milk samples collected from females in different lactational stages. The pups were assayed at postnatal days 2 (P2), 6 (P6) and 15 (P15) in a series of paired-choice tests opposing either murine milk and a blank (water), or two samples of milk collected in …
The Antioxidant Potential of White Wines Relies on the Chemistry of Sulfur-Containing Compounds: An Optimized DPPH Assay
2019
The DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay is an easy and efficient method commonly used to determine the antioxidant capacity of many food matrices and beverages. In contrast with red wines, white wines are poorer in antioxidant polyphenolics, and the more hydrophilic sulfur-containing compounds in them may contribute significantly to their antioxidant capacity. The modification of the classical DPPH method, with a methanol-buffer and the measure of EC20 (quantity of sample needed to decrease the initial DPPH concentration by 20%) has shown that sulfur-containing compounds such as cysteine (0.037 ±
Gestión de los productos alimentarios en Lattara (Lattes, Francia), entre el 450 y el 400 a.n.e.
2009
International audience; En este trabajo se presenta una aproximación a la alimentación de los habitantes de la ciudad portuaria de Lattara durante la segunda mitad del siglo V a.n.e., principalmente a partir de los restos bioarqueológicos. Se examina cuales fueron los alimentos principales (cereales, leguminosas, frutos, carnes y pescados) y su utilización cotidiana. El estudio del estado en que se encontraban al llegar a la ciudad, su almacenamiento, preparación, consumo y gestión de los residuos generados, forma parte de una investigación que pretende combinar los diferentes datos arqueológicos relacionados con la naturaleza diversa de estos productos.; Ce travail présente une approche à …

Matching beer with food : pairing principles, underlying mechanisms and a focus on aromatic similarity
2018
Pairing between beer and dishes emerges as a new trend in France. Beer promoters or gastronomy professionals need to offer high-quality advices in terms of beer and food pairing to their customers. Within this context, the objective of the research was to identify pairing principles and to better understand the underlying perceptual mechanisms. Determinants of food and beverage pairing were first analysed from experts’ discourses. Results showed that food and beverage pairings are governed by perceptual, conceptual and affective features, related to physio-chemical, perceptual and cognitive processes. Experts often mentioned “Aromatic Similarity” as one of the main pairing principles. This …
Mammary pheromone-induced odour learning influences sucking behaviour and milk intake in the newborn rabbit
2016
Newborn rabbits, Oryctolagus cuniculus, locate their mother's nipples through typical orocephalic movements elicited by odour stimuli, in particular by the mammary pheromone (MP). The MP also promotes neonatal odour learning: after single pairing with the MP, an initially neutral odorant becomes able to elicit sucking-related head-searching/oral-grasping movements. However, the behavioural significance of the MP-induced odour learning remains poorly understood. We carried out three experiments to explore its influence on milk intake and compare its consequences with those resulting from nursing-induced conditioning. First, pups conditioned to an odorant by pairing with the MP on postnatal d…
