The constant confrontation with food cues can trigger overeating, wherefore more and more people are suffering from overweight. Originally, gustatory disgust had the function of a warning indicator for potentially harmful nutriment and, as a consequence, inhibited food intake. Therefore, this study investigated possible effects of a bitter aftertaste (gustatory disgust induction) on the processing of visual food cues in overweight people (OW) vs. normal-weight people (NW). Furthermore, it was of special interest in what way food-related disgust proneness (FDP) has an influence on this. For this reason 37 female OW and 37 female NW participated in this fMRI-study. They were presented with images of sweet dishes and vegetables during the recording of their brain activation, once in combination with a bitter and once with a neutral aftertaste, in a retest design. FDP was surveyed in a pre-investigation. In the case of a bitter (vs. neutral) aftertaste, NW showed increased activation in operculum, accumbens, amygdala, hippocampus, pallidum and thalamus compared to OW during the viewing of sweet dishes (vs. vegetables). Furthermore, FDP had a different influence on NW and OW in the mentioned neural processing. While FDP of NW correlated positively with activation in insula, DLPFC, mPFC, ACC, OFC, GTS, thalamus and cerebellum, FDP of OW correlated positively only with activation in pallidum. The results of this research indicate that gustatory disgust induction in NW has a greater impact on the processing of food cues than it does on OW. NW seem to be more aware of the contradiction between the two stimuli because of a more successful multisensory integration of these. A higher FDP seems to reinforce this in NW. An interaction of FDP and weight status therefore seems to be relevant. Nevertheless, further studies are needed to draw more precise conclusions about the meaning of this.
