Fatty taste variability in obese subjects: the oral microbiota hypothesis star

{Origin of the great inter-individual variability of the fatty taste perception found in obese subjects is challenging. The fact that recent studies suggest interrelations between taste perception and oral microbiota composition, prompt us to explore the putative impact of such a connection in the context of obesity. To check this hypothesis, the oro-sensory perception thresholds of linoleic acid and the composition of oral microbiota surrounding the gustatory circumvallate papillae (CVPs) were analyzed in obese adult men (BMI >= 30 kg/m(2)
