The 'Freakonomics of food'
The good news behind our mindless eating
Do you hate Brussels sprouts because your mother did" Does the size of your plate determine how hungry you feel" Why do you actually overeat at healthy restaurants"
"You can ask your smartest friend why he or she just ate what they ate, and you won’t get an answer any deeper than, 'It sounded good,'" says Brian Wansink, Ph.D.), author of "Mindless Eating: Why We Eat More Than We Think," and Professor and Director of the Cornell Food and Brand Lab.
Dubbed the "Freakonomics of food" by the Canadian Broadcasting Commission, Mindless Eating, uses hidden cameras, two-way mirrors, and hundreds of studies to show why we eat what and how much we eat. "The unique thing about his work is that it cleverly answers everyday questions about food and shows translates them into Good News – how we can improve it," said Seth Roberts, Ph.D., a psychology professor at the University of California at Berkeley.
Take how much we eat. Wansink claims we typically don’t overeat because we are hungry or because the food tastes good. Instead we overeat because of the cues around us – family and friends, packages and plates, shapes and smells, distractions and distances, cupboards and containers.
Consider your holiday ice cream bowl. If you spoon 3 ounces of ice cream onto a small bowl, it will look like a lot more than if you had spooned it into a large bowl. Even if you intended to carefully follow your diet, the larger bowl would likely influence you to serve more. This tricks even the pros.
During one holiday party, Wansink and his Lab put this to the test by inviting 63 distinguished nutritional science professors at a leading university to an holiday ice cream social. When they arrived, they were given either medium-size 17-ounce bowls or large-size 34-ounce bowls. "Even though these people think, sleep, lecture and study nutrition," Wansink said, "They still served themselves and ate 31 percent more ice cream (106 more calories) if they had been given a big bowl."
If experts can’t control mindless eating, what help is there for the rest of us" Here’s the good news reassures Wansink, "As Mindless Eating shows, what we eat and how much we eat – is so automatic, the easiest changes are those that are smallest."
At a holiday buffet" Use a smaller plate, or put only two items on your plate during any given trip to the table. Return as many times as you like, but only take two items each time.
Meticulous studies outline why we are consistently influenced, but they also provide the silver lining. If we know that we tend to pour 28% more into short wide glasses than in tall thin ones, the secret is simply getting rid of the short glasses.

不假思索饮食背后得到的好消息
你是否像你母亲那样不喜欢吃芽甘蓝？是否因为你吃饭盘子的大小决定了你感觉饥饿的程度？为什么你在健康餐馆里仍然过度饮食？
你可以问问你最好的朋友他们为什么要吃他们所吃的食物，但是你并不能得到比起“因为它感觉好吃”这样答案更深入的回答。《不假思索饮食：为什么我们吃得比我们想得多》一书的作者，康奈尔大学康奈尔食物及品牌实验室主任及教授Brian Wansink博士发表以上言论。
加拿大广播公司为了证实食物的魔鬼经济学，考察不假思索的饮食，使用了隐藏的摄像机、单面透明的镜子以及数百次的努力来表明我们要吃什么和我们吃了多少。“关于这项研究得到了一个独特的结论，它清楚的解释了每天关于饮食的问题以及我们怎样使它向好的方面发展（我们怎样来改善它）。”加利福尼亚大学心理学教授Seth Roberts说道。
我们到底吃多少。 Wansink宣称我们并不会因为我们饥饿或者是食物味道好而过度饮食。相反我们过度饮食是因为围绕在我们身边的诸多暗示——家庭和朋友、食品包装和盘子、性状和气味、娱乐和距离、橱柜和容器大小。
考虑一下你假日用的冰淇淋碗。如果你舀3盎司的冰淇淋到一个小碗里和一个大碗里，小碗看起来就比大碗显得多得多。如果你希望认真遵循你的饮食节食计划，那么更大的碗对你的影响更明显。这个计谋看起来很明显。
在一个假日派对中，Wansink和他的研究小组把上面情况作为实验进行考察。他们邀请了63名一流大学著名的营养学教授参加一个冰淇淋派对，当他们来到时，每人发一个17盎司或者34盎司的冰淇淋碗。“尽管大家有的在思考，有的在睡觉，有的在讲演或者研究营养学，”Wansink说，“但是他们仍然吃了不少冰淇淋，其中拿大碗的比那小碗的多吃了31％（相当于多吃106卡路里的热量）。”
