肥胖者美食嗅覺更靈敏

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.

據(jù)英國《每日郵報(bào)》報(bào)道，最新研究發(fā)現(xiàn)，越胖的人對美食的嗅覺越靈敏。即食物嗅覺誘惑越大，食欲必然大增，進(jìn)食情不自禁，體重自然增加。科研員研究了人們在饑腸轆轆或者吃飽肚子時(shí)的嗅覺能力。結(jié)果發(fā)現(xiàn)，參試者吃飽飯之后對食物氣味的嗅覺判斷更準(zhǔn)確更靈敏，對非食物類氣味的嗅覺敏感度則反之。由此可以推測，與BMI（身體質(zhì)量指數(shù)）較低者相比，BMI較高者食物嗅覺敏感度更高。
