Taste of Fat: A Sixth Taste Modality?
2015
International audience; An attraction for palatable foods rich in lipids is shared by rodents and humans. Over the last decade, the mechanisms responsible for this specific eating behavior have been actively studied, and compelling evidence implicates a taste component in the orosensory detection of dietary lipids [i.e., long-chain fatty acids (LCFA)], in addition to textural, olfactory, and postingestive cues. The interactions between LCFA and specific receptors in taste bud cells (TBC) elicit physiological changes that affect both food intake and digestive functions. After a short overview of the gustatory pathway, this review brings together the key findings consistent with the existence…
Disentangling nutrition facts from fiction : towards healthy and sustainable consumption in industrialized societies
2020
Over the last centuries, in the context of industrialization, globalization and urbanization, profound dietary changes have occurred. Ubiquitous access to cheap, readily available and highly palatable unhealthy products, together with aggressive marketing that forcefully impacts social norms, have led to overconsumption of energy-dense, nutrient-poor foods. This has not only been associated with a higher prevalence of obesity and diet-related non-communicable diseases, but also with detrimental effects on the world’s natural resources. Broader and braver public health measures favoring the availability and affordability of healthy, minimally processed foods should be implemented in conjunct…
The Representation of Shopping in Children’s Books
2016
Purpose The purpose of this paper is to identify the representations, figures and processes of shopping/commerce in books published in France that are aimed at three to seven-year-olds. Design/methodology/approach A semiotic analysis of nearly 50 books published over the past 60 years. Findings These books reveal a broad diversity in the images of shops given to children (ranging from the traditional shop, a source of pleasure and creator of social ties, to the hypermarket/megastore, a symbol of stress and overconsumption) and the wealth of information that is given to children to help them assimilate the process of a shopping transaction. Originality/value The originality and richness of …
Orosensory Perception of Dietary Lipids in Mammals
2008
Obesity constitutes a major public health problem for the twenty-first century, with its epidemic spread worldwide, particularly in children. The overconsumption of fatty foods greatly contributes to this phenomenon. Rodents and humans display a spontaneous preference for lipid-rich foods. However, the molecular mechanisms underlying this pattern of eating behaviour in mammals remain unclear. The orosensory perception of dietary lipids was long thought to involve only textural and olfactory cues. Recent findings challenge this limited viewpoint, strongly suggesting that the sense of taste also plays a significant role in dietary lipid perception and might therefore be involved in the prefer…
Rôle des lipides dans la régulation du comportement alimentaire
2008
Obesity constitutes a major public health problem for the 21 st Century, with its epidemic spread worldwide, particularly in children. The overconsumption of fatty foods greatly contributes to this phenomenon. Rodents and humans display a spontaneous preference for lipid-rich foods. But why are lipids so attractive? What are the molecular mechanisms involved? The purpose of this mini review is to explore few basic questions raised by recent data providing evidences on the relationships between dietary lipids and feeding behavior.
Is the taste of fat regulated?
2013
Over the last decade, converging data have been accumulated both in rodents and humans, supporting the existence of a sixth taste modality devoted to the perception of dietary lipids. It is well known that the sense of taste is determinant for the food choice and that the overconsumption of highly palatable energy-dense foods contributes to the current obesity epidemic. Thus, an important issue in terms of Public Health is to understand the mechanisms by which the oro-sensory perception of fat is regulated. An overview of our current knowledge in this field of investigations is proposed in this mini-review.
