Role of food familiarity and taste quality in food preferences of individuals with Prader-Willi syndrome.
OBJECTIVE
To investigate the chemosensory function and food attribute preferences of individuals with Prader-Willi Syndrome.


METHODS
Cross-sectional, matched-groups comparison.


METHODS
Fifteen (eight female and seven male) individuals with Prader-Willi Syndrome and an age- and sex-matched non-affected sample.


METHODS
Intensity ratings of taste and odor stimuli and hedonic ranking of 20 foods varying in sensory attributes (e.g. taste familiarity).


RESULTS
Sensory test performance was comparable in the PWS and control groups. In addition, individuals with Prader-Willi Syndrome showed a pattern of food preferences that was similar to their non-affected counterparts.


CONCLUSIONS
Abnormal chemosensory function does not underlie the ingestive behavior of individuals with Prader-Willi Syndrome.
