From: Obese Subjects With Specific Gustatory Papillae Microbiota and Salivary Cues Display an Impairment to Sense Lipids

Orosensory detection threshold of linoleic acid (LA) determined by using the 3-alternative forced-choice (3-AFC) ascending concentration procedure in normal weight (NW, BMI < 25 kg/m2) and obese (O, BMI ≥ 30 kg/m2) subjects. 3-AFC was carried out on emulsions in an ascending concentration from 0.00028% to 5% LA (wt/wt) spaced by 0.25 log units (18 solutions in total). Data were analyzed according three complementary comparisons: NW vs O, LA taster (T) vs LA non-taster (NT) and obese taster (OT) vs obese non-taster (ONT). To characterize the subjects in function of their oral LA sensitivity, it was arbitrary postulated that individuals displaying a threshold value ≥ 0.5% LA were non-tasters (NT). Geometric means; ns, non-significant, ***p < 0;001.
