Australia is one of several countries experiencing an epidemic of obesity that will have major disease consequences for future decades. Obesity results from sustained liking and surplus intake of foods that override the bodily mechanisms that normally keep bodyweight constant. An important element of overeating is the ability of the sensory properties of foods (flavours) to stimulate short-term appetite. There are close parallels between flavour preference learning in rats and humans. Increasing understanding of the factors that influence persistence of preferences in rats will contribute to more effective programs at both a mass and an individual level for preventing overeating.

澳大利亚是肥胖症流行的几个国家之一，肥胖症将在未来几十年产生重大疾病后果。 肥胖是由于对食物的持续喜爱和过量摄入而导致的，这些食物超越了通常保持体重恒定的身体机制。 暴饮暴食的一个重要因素是食物的感官特性（口味）刺激短期食欲的能力。 老鼠和人类的味道偏好学习之间存在密切的相似之处。 加深对影响大鼠偏好持续性的因素的了解，将有助于在群体和个体层面制定更有效的预防暴饮暴食计划。
