Healthy Women Can Still React as If Anorexic

健康女性也愁胖

A New York Times reporter recently wrote this sentence: "Like most -- heck, all -- of the women I know, my relationship to food, to my weight, to my body is…complicated." That relationship is now visible in our brains.

最近，紐約時(shí)報(bào)的一名記者寫(xiě)了這么一句話：“貌似大多數(shù)——咳，應(yīng)該是所有的我認(rèn)識(shí)的女人，她們與食物、體重和身材的關(guān)系都十分復(fù)雜?！爆F(xiàn)在，這種復(fù)雜關(guān)系已經(jīng)呈現(xiàn)在我們的腦海中了。

When anorexic and bulimic women see images of overweight women, an area of the brain, the medial prefrontal cortex, lights up in a functional MRI. This region is associated with identity and self-reflection.

無(wú)論是患有厭食癥還是暴食癥的婦女，當(dāng)她們看到肥胖超重的婦女形象時(shí)，大腦里的一個(gè)跟身份與自我反思相關(guān)的區(qū)域——內(nèi)側(cè)前額葉皮層——會(huì)活躍起來(lái)，在功能性磁共振成像下可以看到這一區(qū)域變亮。

Researchers at Brigham Young University studied women who seemed to have no major body image issues, based on a standard psychological assessment. This group was supposed to be the healthy controls. The scientists showed the apparently healthy women images of both overweight and thin female bodies. And their medial prefrontal cortex lit up, particularly at images of overweight women.

楊百翰大學(xué)的研究人員對(duì)看起來(lái)沒(méi)有較大體型問(wèn)題的婦女進(jìn)行了研究，這里所界定的“沒(méi)有較大體型問(wèn)題”是基于一個(gè)標(biāo)準(zhǔn)心理評(píng)估而做出的。這組婦女本應(yīng)作為健康對(duì)照組?？茖W(xué)家們對(duì)這些看起來(lái)健康的婦女們展示了超重及過(guò)瘦的女性圖片，發(fā)現(xiàn)她們的內(nèi)側(cè)前額葉皮質(zhì)會(huì)變亮，在看到超重女性形象的時(shí)候尤甚。

When a group of men looked at images of overweight men, there was no medial prefrontal cortex activity. So apparently women, unlike men, see photos of heavy women and think "me too." The authors say that this finding may mean that even apparently healthy women have, under the surface, issues related to food, weight and body image.

而當(dāng)一組男性看到超重男性的形象時(shí)，內(nèi)側(cè)前額葉皮質(zhì)則不會(huì)活躍。因此，女性與男性顯然不同，當(dāng)女人們看到肥胖女性的照片時(shí)，心里會(huì)想“我也是這樣”。作者說(shuō)，這一發(fā)現(xiàn)也許意味著即使是看起來(lái)健康的婦女在心底也會(huì)隱藏著有跟食物、體重和身材相關(guān)的問(wèn)題。
