雙語：付出勞動越多 食物越美味

　　According to the Daily Telegraph of November 8, the feeling that you have earned a reward actually increases the pleasure you take from it, a new study suggests。

　　Now the authors believe this principle could be used to train people to like more healthy food over sugary and fatty snacks。

　　Alexander Johnson, a psychologist at Johns Hopkins University in Baltimore, said: "Basically, what we have shown is that if you have to expend more effort to get a certain food, not only will you value that food more, but it might even taste better to you. At present, we don't know why effort seems to boost the taste of food, but we know that it does, and this effect lasts for at least 24 hours after the act of working hard to get the food."

　　The study seems to suggest that hard work can even enhance our appreciation for fare we might not favour, such as the low-fat, low calorie variety。

　　The experiments, published in the Proceedings of the Royal Society B, were on mice but it is believed they are transferable to humans。

　　Mr. Johnson said: "We then analysed the way in which the mice consumed the food. Why did we do this? Because food intake can be driven by a variety of factors including how it tastes, how hungry the mice were beforehand and how 'sated' or full the food made them feel."

　　Mr. Johnson and Professor Gallagher used licking behavior as a measure of the rodents' enjoyment of their treats。

　　It found the mice that had to work harder for their low-calorie rewards were more likely to keep licking their lips and savouring it。

　　據(jù)英國《每日電訊報》11月8日報道，一項最新研究表明，獲得獎勵會增加人們的快樂感。

　　現(xiàn)在，研究作者認為這一原則可以讓人們愛上健康食物，舍棄含糖和高脂肪食物。

　　巴里摩爾約翰?霍普金斯大學(xué)心理學(xué)家Alexander Johnson表示："我們的研究結(jié)果基本上顯示，人們不僅會更加珍惜通過辛勤努力獲取的食物，而且會覺得食物更加香甜可口。目前，我們尚未了解為什么勞動會讓食物嘗起來更加美味，然而事實的確如此。通過勞動努力獲取食物的成就感會持續(xù)至少24小時。"

　　這項研究似乎表明，我們可能會更加珍惜努力勞動換取的食物，即使是那些我們并不喜歡的食物， 如低脂肪、低熱量食品。

　　此項刊登在英國皇家學(xué)會學(xué)報B版的研究實驗，雖然實驗對象是小老鼠，但是專家相信結(jié)論對人類同樣適用。

　　Johnson說："我們對老鼠食用食物的方式進行分析。我們?yōu)槭裁匆@樣做呢？是因為老鼠食物攝取量由多種因素決定，包括食物味道如何，實驗前老鼠的饑餓程度以及食物本身的油膩感和飽食感等等。

　　Johnson 先生和Gallagher教授用動物的舔舐行為來判斷他們享受美食的快樂程度。

　　結(jié)果發(fā)現(xiàn)，那些不得不勤勞努力以換取低熱量食物的老鼠不停地舔舐自己的嘴唇來品嘗食物，(表示食物很美味)。
