"brain" news and stories

You know that little voice in your head that looks at a big plate of fresh cookies and whispers, "You'd better eat just one?" Turns out, in people who are already obese, it may be a teeny-tiny voice or missing altogether.

That's the finding of brain researcher Dr. Antonio Convit, a professor of psychiatry and medicine at the New York University School of Medicine and the Nathan Kline Institute, reports New Scientist magazine. Convit and others have long been aware that type 2 diabetes is associated with memory difficulties, the result of a diabetic's inability to increase fuel for the brain to conduct the kind of problem solving that will, for instance, allow them to remember where the heck they put their car keys.

Figuring something similar might occur in people who were obese, Convit looked at the brains of 44 middle-aged obese people and 19 lean ones, using MRI's and other tests.

What he found were changes in the obese subjects in two parts of the brain that play major roles in eating. In obese people there was more water in the amygdala, which, among its functions, regulates feeding behavior. He also found that the orbital frontal cortex of the brains of obese people was smaller, which meant it had less ability to perform one of its key functions -- inhibit automatic responses -- such as the impulse to eat that whole plate of cookies.

Time Magazine reports, with a soupçon of punny glee, that sales of offal in Great Britain have surged as of late, likely in response to the international economic downturn. Quoth London's Liz Logan:

"Tough economic times have Britons eating their hearts out and swallowing their tongues. Not literally, of course. But offal - or "variety meats," as the food category is euphemistically called in the U.K. - is experiencing a surge in popularity, with sales up 67% over the past five years."

Thing is, even in advance of the pound sterling's plunge, the nose-to-tail herd, helmed by offal stalwarts like Fergus Henderson and River Cottage's Hugh Fearnley-Whittingstall, had been squealing 'bout the culinary benefits of tripe, kidneys, brains, tail, giblets and trotters. Come for the savings, stay for the savoring -- the message seems to have come home to roost.

I posted a while back about my love of grilled chicken hearts, and I'm no stranger to whisking up a batch of giblet gravy, or a neckbone ragout, but I'm hungry for your favorite takes on organ meats. Post 'em in the comments below.

The obesity epidemic in the US has been well documented, but could it be caused, at least in part, by thinking? There's a new study out that indicates thinking could contribute to an expanding waistline.

Researchers split participants into three groups: one group just rested, one had to read, the last one had to complete mental tests on a computer. Then all the participants were allowed to eat whatever they wanted to. Even though they only used about three more calories, the groups who were using their brains ate 200 (the readers) and 250 (the computer test takers) more calories. Through extensive blood sample-taking (before, during, and after the experiment), the researchers found wide variations in blood glucose levels from different phases of the experiment.

They concluded that "the body reacts to these fluctuations by demanding food to restore glucose, a sugar that is the brain's fuel. Glucose is converted by the body from carbohydrates and is supplied to the brain via the bloodstream. The brain cannot make glucose and so needs a constant supply. Brain cells need twice as much energy as other cells in the body. "

They cautioned that people who have intellectually demanding jobs should keep this in mind when they're choosing what and how much to eat. I think we all need to keep this in mind, as well as get out of the office to go for a walk.

I'm interrupting the semi-regularly scheduled Midnight Sausage series to share molded food images and recipes from my personal collection of early-to-mid 20th century cookbooks. There will be aspic. There will be mousse. There will be various gelatins. All will be semi-solid and of debatable degrees of edibility.

Please feel free to shimmy and shake your way to the comments section to share your very own magical, masticable molds of yore.

When it comes to chocolate, there are two types of people: cravers and noncravers. It is interesting to note this because, unlike the vast majority of foodstuffs, people feel very strongly about their love of chocolate and often seem to find it to be "incredible" that not everyone loves the stuff.

Those who crave it experience an unusual reaction just from looking at it. A new study shows that simply looking at chocolate can activate the pleasure centers in a brain of a chocolate-lover. In fact, the part of the brain that is involved in drug addiction, the ventral striatum, turned on in response to the images, though noncravers did not have any activity in this part of the brain. Not surprisingly, when the viewing was combined with a taste of chocolate, their reaction (within the pleasure centers of the brain) was very strong. Noncravers also did not report that tasting the chocolate was as pleasant as the cravers did.

No on yet seems to have any idea as to why some crave chocolate and others don't, but some scientists say that the results of this study, indicating a clear desire-reward reaction to chocolate, could help "people change their diets or control cravings" for chocolate and possibly other foods. But when it comes to chocolate, who would want to?
