Obesity interferes with the orosensory detection of long-chain fatty acids in humans
Background: The association between the orosensory detection of lipids, preference for fatty foods, and body mass index (BMI; in kg/m 2 ) is controversial in humans. Objective: We explored the oral lipid-sensing system and the orosensory-induced autonomic reflex system in lean and obese subjects. Design: Lean (BMI: 19 to ,25; n = 30) and obese (BMI .30; n = 29) age-matched men were enrolled. Their oral threshold sensitivity to linoleic acid (LA) was determined by using a 3-alternative forced-choice ascending procedure, and their eating habits were established by the analysis of 4 consecutive 24-h food-consumption diaries. The effect of brief oral lipid stimulations on plasma triglyceride [(…
What does it matter for consumers: sensory pleasure or health? A willingness to exchange approach
International audience; Sensory pleasure and health concerns are two often conflicting dimensions of food choices. Consequently, it is important to develop methods to assess the relative importance of immediate sensory pleasure and future health benefits in consumers’ decisions. In the present experiment, the impact of sensory characteristics and nutritional labelling was examined for a snack product: chips. Three variants of chips were used: a regular recipe, a low salt version, and a low fat one. They were presented to 124 consumers in three different conditions: blind condition where consumers tasted the chips, product’s label (the expected liking was evaluated), and full information con…
Impacts of obesity on the oro-sensory perception of lipids in Human
Accumulating evidences support the existence of a fatty acid taste both in rodents and humans. A recent study performed in lean subjects suggests the existence of a positive correlation between the oro-sensory perception of dietary lipids and body mass index (BMI) in Human. It was extrapolated that obesity might promote overconsumption of fatty foods by decreasing the detection of lipids in oral cavity. To explore this hypothesis, linoleic acid (LA) detection threshold was determined in lean (18>BMI 30, n=29) volunteers using a 3-alternative force choice ascending concentration presentation procedure in conditions known to minimize other sensory cues. A large distribution of LA detection wa…
