Mean values ± SEM of erythrocyte saturated fatty acid (SAFA) levels and the palmitic/linoleic acids ratio (PA/LA), plasma levels of free fatty acid (FFA) and retinol measured in supertaster (N = 9), medium taster (N = 28) and non-taster (N = 23) participants with normal weight (NW) and supertaster (N = 12), medium tasters (N = 25) and non-taster (N = 13) participants with obesity (OB). (a) Erythrocyte SAFA values. (b) Erythrocyte palmitic/linoleic acids ratio (PA/LA). (c) Plasma free fatty acid (FFA) values. (d) Plasma retinol values. A two-way analysis of variance (ANOVA) was used to compare the differences across taster groups in participants with normal weight or with obesity (SAFA, PA/LA: P < 0.00068 and FFA: P = 0.0243). The different letters indicate significant differences (SAFA: P < 0.0069; PA/LA: P < 0.0214; retinol: P = 0.0333; Newman-Keuls test). *A significant difference between participants with normal weight or with obesity (P < 0.0265; Newman-Keuls test). ST, supertaster participants; MT, medium taster participants; and NT, non-taster participants.
