Previous research has found that alcoholics have a greater preference for sweet solutions than comparison subjects. This study tested the hypothesis that preference for sweet solutions is a marker for alcoholism risk.
A total of 122 nonalcoholic subjects (59 men) participated. Fifty-eight subjects had a paternal history of alcoholism, and 64 did not. Each subject rated a series of sucrose solutions for intensity of sweetness and degree of preference.
Subjects were able to rate accurately the relative intensity of sweetness in the sucrose solutions. Both subjects with and those without a paternal history of alcoholism preferred a 0.42-M sucrose solution, irrespective of gender.
This study failed to support the hypothesis that sweet preference is a marker of alcoholism risk. The sweet preference observed previously among alcoholics may be a consequence of chronic alcohol consumption or other factors associated with heavy drinking.
先前的研究发现，酗酒者比对照对象对甜味溶液有更大的偏好。本研究检验了甜味溶液偏好是酒精中毒风险标志物这一假设。
共有122名非酗酒受试者（59名男性）参与。58名受试者有父亲酗酒史，64名没有。每位受试者对一系列蔗糖溶液的甜度强度和偏好程度进行评分。
受试者能够准确评定蔗糖溶液中甜度的相对强度。无论性别，有和没有父亲酗酒史的受试者都偏好0.42M的蔗糖溶液。
本研究未能支持甜味偏好是酒精中毒风险标志物这一假设。先前在酗酒者中观察到的甜味偏好可能是长期饮酒或与大量饮酒相关的其他因素的结果。
