Early development of taste and flavor preferences and consequences on eating behavior
2018
The first 1000 days of life constitute an important period for development of health and eating behavior, in particular because the mode of feeding drastically evolves, which involves that the child has to learn “how” to eat, but also “what” to eat, “how” much food to eat. After birth, when foods are orally exposed, infants discover the intrinsic properties of foods, with a variety of tastes, flavors, textures, as well as energy densities. Here we focus on deciphering the involvement of taste and olfaction in the early establishment of eating behavior. In the OPALINE French birth cohort (Observatory of Food Preferences in Infants and Children), taste and flavor preferences were studied in c…

Role of human metabolizing enzymes in food perception
2022
Flavor is the main factor determining food acceptability. Flavor corresponds to the combination of the signals from the gustatory system, the olfactory system and the trigeminal system. Interactions between proteins and flavor molecules in oral/nasal cavities are proposed to modulate flavor perception through a series of events knowns as perireceptor events. Among these proteins involved in this modulation are found enzymes mainly known for their role in the detoxification process. These enzymes are able to recognize a large panel of molecules. We proposed to explore the role of these enzymes in food perception. We demonstrated that enzymatic activities present in the oral epithelium and sa…
How does taste influence food preferences and food intake in early childhood?
2012
Humans are born with very few flavor preference. The most consistent observations concern taste: newborns exhibit an early attraction for the sweet taste, in opposition to the avoidance of the bitter taste. Odor preferences are less obvious and are generally related to prenatal learning and/or have biological relevance (Schaal, 2006). The objectives of this presentation will be to describe the early taste preference, how they evolve in early infancy (Schwartz, Issanchou, & Nicklaus, 2009), and how the taste of the foods or the individual attraction toward tastes might influence food preference in infancy (Schwartz, Chabanet, Lange, Issanchou, & Nicklaus, 2011), as well as food intake in ear…

Piecing together the taste signaling puzzle
2010
International audience; The identification of the genes coding for bitter, umami, sweet and sour taste receptors has provided us with unique tools to investigate the gustatory system. As a consequence, tremendous progress towards our understanding of the functional organization of the peripheral taste system has been achieved over the past decade. In particular, key components of the taste receptors signaling cascades have been identified as well as populations of chemosensory cells in the olfactory, respiratory and digestive systems expressing taste receptors. Besides sharing receptors and signaling molecules (gustducin, phospholipase-C b2…) with taste bud cells, these cells display a simi…
