Previous studies reportthat the ingestion of highly concentrated sweet solutions produces amorphine-like analgesia in rats, human infants, and in adult males. Todetermine whether sweet-induced analgesia occurs with more commonly consumedsubstances, 30 adult males Mage = 22.4 years were exposed to a cold pressor test andpain responsivity was assessed both before and after consuming either an 8%sucrose solution, water, or nothing. Between-groups comparisons revealed that relative to the Sucrose or Nothing groups,the Water group showed increased pain tolerance. Neither pain thresholds norratings of pain intensity and unpleasantness on a visual analogue scalediffered among groups. The results support previous findings in both humans andanimals that the palatability or hedonic value of food or drink may be the keypredictor of its analgesic effect.
