The 'Freakonomics of food'

27.11.2006
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.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...

Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, according to Rice University...
