Repeatedly drinking a novel drink while thirsty increased consumption of that drink, but did not change liking ratings. This suggests learned thirst responses may influence beverage intake.

Area of Science:

  • Food science
  • Behavioral science
  • Sensory science

Background:

  • Thirst and hydration significantly influence food and beverage preferences.
  • Learned associations between flavors and physiological states can shape consumption patterns.

Purpose of the Study:

  • To investigate if repeated exposure to a flavored drink while thirsty influences subsequent liking and consumption.
  • To compare the effects of drinking a novel beverage after high-salt versus low-salt meals on learned preferences.

Main Methods:

  • A within-subject design was employed with participants consuming flavored drinks (H and L) after high-salt and low-salt meals across multiple sessions.
  • Pre- and post-training assessments measured drink pleasantness and thirst-quenching effects.
  • A final choice test allowed ad libitum consumption after a high or low salt meal.

Main Results:

  • Participants consumed nearly twice as much of the drink (H) associated with the high-salt meal compared to the drink (L) associated with the low-salt meal in the final choice session.
  • Despite increased consumption, there were no significant differences in rated liking or choice behavior based on past training.
  • Increased consumption of H may indicate unmeasured liking or a learned "conditioned thirst" response to its flavor.

Conclusions:

  • Repeatedly drinking a novel beverage while thirsty can increase its consumption, potentially through mechanisms beyond simple liking ratings.
  • Learned associations, such as conditioned thirst, may play a crucial role in beverage intake regulation.
  • Further research is needed to differentiate between learned liking and conditioned thirst in beverage choice behavior.
