华盛顿大学医学院的研究者发现，肥胖人群对油腻食物的渴望可能跟他们体内的一种叫CD36的受体蛋白质的指数有关。

Those with more of it are better at detecting the presence of fatty food, and seemingly less likely to gorge on it. Twenty-one overweight people were asked to taste solutions from three cups and point to which was different. One contained small amounts of a fatty oil, while the other two were fat-free.

CD36受体指数越高，对油腻食物的识别能力就越好，也就不太可能暴饮暴食高脂肪的油腻食物。研究者要求31名超重人士品尝三杯溶液然后指出哪一杯不同。其中一杯含有少量的脂肪油，其他两杯则不含。

Participants who made the most CD36 were eight times more sensitive to the presence of the fat than those who made around half the amount.

体内含有最多CD36受体的实验参与者，对脂肪的敏感度要比其他只有一半CD36的参与者高8倍。

Researcher Professor Nada Abumrad said the finding could help treat obesity by finding a way to increase sensitivity to it.

实验的研究者、Nada Abumrad教授表示，这一发现可以通过提高对脂肪的敏感程度来治疗肥胖症。

‘What we will need to determine in the future is whether our ability to detect fat in foods influences our fat intake, which clearly would have an impact on obesity,’ she said.
