    Taste preferences for sugar and fat differ in women with eating disorders. Anorectic patients prefer sweet, dislike fat, and maintain these preferences even after weight recovery, suggesting taste responsiveness is independent of weight status.

    Area of Science:

    • Neuroscience
    • Psychology
    • Nutrition Science

    Background:

    • Eating disorders are complex conditions affecting food preferences and intake.
    • Understanding taste perception in eating disorders is crucial for developing targeted interventions.
    • Previous research suggests altered taste sensitivity in individuals with eating disorders.

    Purpose of the Study:

    • To investigate taste responses to sucrose and fat in young women with various eating disorders.
    • To compare taste preferences between patients with anorexia nervosa and bulimia nervosa and healthy controls.
    • To determine if taste preference profiles change with weight status or diagnostic subtypes.

    Main Methods:

    • Assessed sensory estimates of sweetness and fat content in 20 different sugar-fat mixtures.

  • Utilized the Response Surface Method to determine relative preferences for sugar versus fat.
  • Compared taste responses across groups: anorectic-restrictor, anorectic-bulimic, normal-weight bulimic, and normal-weight controls.

    • Main Results:

    • No significant differences in sensory estimates of sweetness or fat content were found among the groups.
    • Significant differences in relative sugar versus fat preferences emerged between eating disorder patients and controls.
    • Anorectic-restrictor and anorectic-bulimic patients showed a preference for sweet, aversion to high-fat stimuli, and elevated optimal sugar:fat ratios.
    • Normal-weight bulimic patients preferred sweeter stimuli compared to controls.
    • These preference patterns remained stable even after weight regain in anorectic patients.

    Conclusions:

    • Taste responsiveness, particularly the preference for sweet and aversion to fat, may be an intrinsic characteristic of certain eating disorders.
    • Preference profiles appear independent of diagnostic subtypes, bulimic behaviors, or acute changes in body weight.
    • These findings suggest that altered taste preferences could be a stable trait rather than a consequence of the disorder's current state.
