Comfort Food and Social Stress

Comfort Food, for Monkeys is John Tierney’s article today, reporting on recent research by Mark Wilson and colleagues at Yerkes Primate Center about rhesus monkeys, sweet tooths, social stress and inequality. Familiar themes, all of them.

Normally, low-status monkeys eat roughly the same amount of bland monkey chow as dominant individuals. But add sweet banana-flavored pellets to the mix, and suddenly the equation changed: “While the dominant monkeys dabbled in the sweet, fatty pellets just during the daytime, the subordinate monkeys kept scarfing them down after dark.”

Tierney goes on to outline reasons why this scarfing vs. dabbling dynamic might emerge in socially complex species like rhesus monkeys. As Wilson et al. note in their paper, “this ethologically relevant model may help understand how psychosocial stress changes food preferences and consumption leading to obesity.”

Tierney describes research by Dallman et al., who have proposed that people can directly impact stress hormones through eating, largely by mediating anxiety: “[P]eople eat comfort food in an attempt to reduce the activity in the chronic stress-response network with its attendant anxiety.” So individuals with greater stress reactivity and negative mood tend to eat more in their stressed vs. control experimental paradigm.

As Tierney notes with a quip about a “stressed-out wage slave who has polished off a quart of Häagen-Dazs at midnight while contemplating the day’s humiliations,” inequality can bring on stress reactivity and negative mood (for more on that, see previous stress and inequality posts on Sapolsky and Blakey). In turn, inequality feeds into the obesity epidemic through both social and cultural dynamics.

But Tierney also knows that seeking food, not simply reactive eating, is key to overall weight gain. Continue reading “Comfort Food and Social Stress”

College Drinking: Battle of the Sexes?

By: Carolyn, Andrew, Brandon, and Sarah

Drunk- this five letter word has many connotations, ranging in extremes from positive memories to negative stigmas. For men and women, it is one word that has different meanings, from the number of drinks it takes to get drunk to the behaviors men and women are expected to exhibit while drinking. For college women and men in particular, binge drinking is an area in which they relate quite distinctly with alcohol. Gender norms, rituals and relations often lead to, and perpetuate, binge drinking on campuses nationwide.

Many aspects of college drinking are unique. Tailgating is one of them. Where else can you find people drinking excessive amounts of alcohol early in the morning? At big football schools, tailgating facilitates the social learning of binge drinking as a normal and acceptable behavior. The ritualized drinking associated with tailgating is often the first place where students are introduced to binge drinking. It also sets a precedent of drinking enough alcohol to get drunk and stay drunk for an extended period of time.

In the fall, people tailgate every weekend before football games. In the ritual of tailgating, binge drinking as a socially learned experience is evidenced by the fact that students learn to drink from the very alumni whom they are taught to respect and admire. Across the nation, students only need to leave their dorms to encounter the alumni who have been drinking since early morning. Since this is often a student’s first exposure to binge drinking, students may initially be shocked to find huge crowds of people drinking heavily in parking lots and around campus. The immersion in the football culture, which often depends upon tailgates, will soon numb any hesitation or doubts the student may have.

Tailgating perpetuates binge drinking among the general student population, but its significance varies based on gender. During a typical night out, a college student may consume four or five drinks to “pregame” before the actual party has even started. Many students do not realize that this qualifies as binge drinking, and that it impacts women and men differently.

Ethnography and the Everyday: Knapp’s Appetites

In my medical anthropology class we are now reading Caroline Knapp’s Appetites, a memoir of her struggles with anorexia and a meditation on culture, gender, and being a woman. This book is flip side to Kolata’s Rethinking Thin, linking eating and weight to cultural meanings, social relationships, the media, and more. In the end, I hope that my students will realize that both biology and culture matter, and that one of the best ways to link those two is through a focus on experience and behavior. In turn, experience and behavior can be grasped as being the manifestation, concretization and direction of brain and body in context.

On Thursdays the students take charge of half the class, and yesterday was a great discussion. The group in charge began with Knapp’s discussion of the front cover of a Shape magazine featuring Elle Macpherson, perfectly recovered after giving birth just some months before. Then they put all of us to work on creating the covers for other magazines—Seventeen, Cosmopolitan, Women’s Health, and Men’s Health. We’re on deadline and have to sell, sell, sell

Bad brain science: Boobs caused subprime crisis

I’m too busy to be blogging right now; I’m putting in an application for academic promotion, and like much else in academe, that means reams of paper must be offered up to the cruel, fickle gods of bureaucracy. But this example of the reporting on brain imaging research, drawn to my attention by Amanda Marcotte of Pandagon’s, Using 15 college age boys and some reactionary reporting, we are able to blame the coming depression on boobage, couldn’t pass by without comment. Thank YOU Amanda for getting me worked up enough that I won’t need a morning cup of coffee to get through several hours working on my promotion application, if I can just get back to that. (Thanks also to Echidne of the Snakes.)

The article which inspired this train of commentary is ‘Sex and financial risk linked in brain,’ by Seth Borenstein, who probably needs some sort of award for this piece. I’ll let you decide:

A new brain-scan study may help explain what’s going on in the minds of financial titans when they take risky monetary gambles — sex. When young men were shown erotic pictures, they were more likely to make a larger financial gamble than if they were shown a picture of something scary, such a snake, or something neutral, such as a stapler, university researchers reported. The arousing pictures lit up the same part of the brain that lights up when financial risks are taken.

“You have a need in an evolutionary sense for both money and women. They trigger the same brain area,” said Camelia Kuhnen, a Northwestern University finance professor who conducted the study with a Stanford University psychologist.

Encephalon at Of Two Minds

The most recent edition of the brain sciences blog carnival, Encephalon, is being hosted on the blog, Of Two Minds. Encephalon Goes to Paris (Hilton) includes a couple of references to work here on Neuroanthropology, but we do get called out on our severe reservations about twin studies (ooooo… don’t get me started…).

This won’t be news to many of you. In fact, a fair few of the visits we’ll get over the next few days will probably come from Encephalon-related browsers, but if you don’t already know about it, there’s a pile of interesting material in this edition. I won’t even attempt to summarize all the interesting stuff that you’ll find links to on everything from video games to synesthesia to the history of lithium to olfaction and sensing danger. If you’re not visiting here from there, you may want to pay a visit.

Neurosexism, size dimorphism and not-so-‘hard-wiring’

Cordelia Fine has a great short piece, Will Working Mothers’ Brains Explode? The Popular New Genre of Neurosexism, on the recent spate of work about the ‘female brain.’ In the article (which is short but worth reading, including for the other material she links to), she explores ‘several recent popular and influential books arguing for fundamental and “hard-wired” differences in male and female psychology.’ In her discussion, she doesn’t so much focus on the research itself but on the question, ‘What accounts for the success and appeal of the new field of neurosexism?’ I’m going to take this posting as a license to range all over the place on the ‘biology’ of sex differences, not just in the brain, as a way of thinking more about how culture and biology become inextricably entangled even in basic sexual differences, like say body size.

One explanation for neurosexim, according to Fine, is that ‘Most lay readers, of course, have neither the background nor the resources to question the many inaccurate and misleading claims made about gender differences in the brain,’ a discussion that we’ve already had on Neuroanthropology (both here and here). I especially like a quote that Fine borrows from Mark Liberman: ‘misleading appeals to the authority of “brain research” have become the modern equivalent of out-of-context scriptural fragments’ (originally on Language Log).

Fine presents the example: ‘The back cover of The Female Brain offers to explain why “a man can’t seem to spot an emotion unless someone cries or threatens bodily harm”. Were we to pick up a different sort of book that made an equally unusual sort of claim (a guide to pets, say, which promised to explain why cats can’t climb trees), we would immediately put it down and go in search of a more reliable text.’ It’s a great point; so much of our experience points to myriad exceptions to these neurosexist rules, and yet many of us don’t throw the books out immediately. Odd…
