肥胖者美食嗅觉更灵敏

Fatter people may find food more appealing because they have a more intense sense of smell, new research suggests, the Daily Mail reports. It believed that this might make the food more appetizing to them and so encourage them to eat more. A study was launched to see if being hungry or full had an impact on people's ability to distinguish smells, and it was found that contrary to popular belief people had a heightened sense of smell to food odors after eating. The effect was the opposite for non-food related smells. When the results were analyzed further, it was found that compared to those with a low BMI, people with a higher BMI had a greater sensitivity to the smell of food.

据英国《每日邮报》报道，最新研究发现，越胖的人对美食的嗅觉越灵敏。即食物嗅觉诱惑越大，食欲必然大增，进食情不自禁，体重自然增加。科研员研究了人们在饥肠辘辘或者吃饱肚子时的嗅觉能力。结果发现，参试者吃饱饭之后对食物气味的嗅觉判断更准确更灵敏，对非食物类气味的嗅觉敏感度则反之。由此可以推测，与BMI（身体质量指数）较低者相比，BMI较高者食物嗅觉敏感度更高。
