Impact of obesity on the oro-sensory detection of dietary lipids in mice and humans

2013

Gustation is an essential parameter in the oro-sensory detection of dietary lipids. In mice and most likely in humans, the binding of long-chain fatty acids to the CD36 receptor plays a major role in this oral fat detection. Gustation is involved in the food choice (fat sensitivity) as well as in the preparation of the body to the fat inflow. This oral lipid sensing is highly regulated. As obesity seems to be responsible for an alteration of the basic tastes detection, the aim of this thesis was to investigate whether obesity can impair the oral lipid detection in both mice and humans. In humans, our data show that there is an alteration of the oral fat detection in some obese subjects who …
