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…
