Izvo zvinoshatisa mhedzisiro yekushushikana: kufutisa kunogona kukonzerwa kana kuchengetedzwa nekuwedzera neurobehavioural reactivity kune zvine chekuita nechikafu cues.

Kufutisa uye kushushikana, kudzidza

Zvichienderana nekufungidzira uku, nhamba yezvidzidzo zveurouroimaging ine zvidzidzo zvakapfurikidza zvakaratidza kuwedzera kushandiswa mukupindura kumifananidzo yezvokudya mukati mematunhu ari pasi pemubairo, manzwiro, chiyeuchidzo uye sensorimotor kushanda, uye kuderera kwekushanda mumatunhu ari pasi pekucherechedza uye kuzvidzora.

Mabhuku akasimbiswa, kunyanya mumhuka, aratidza kuti kushushikana mupfungwa kunogona kuve kwakabatana nekuwedzera kwekudya, kunyanya kwezvekudya zvine simba, uye kuwedzera uremu hwemuviri uye adiposity.

Mukutevedzana kwekuedza kunosanganisira kushandiswa kweiyo inoshanda magineti resonance imaging (fMRI) kuyera huropi hunoitwa neural network, vaongorori veJohns Hopkins Medicine (Carnell et al., 2022) vakaongorora kuti kushushikana kunogona sei kuwedzera kudya muvanhu vakuru vakafuta kana vakajairwa. .

Carnell nevamwe vaaishanda navo vakawana kuti kushushikana kunokanganisa mhinduro dzehuropi kune zvinokurudzira chikafu, uye kuti vanhu vakuru vakajairwa uye vakafutisa vanopindura kune chikafu munzvimbo dzehuropi dzine chekuita nemubairo uye kugona kwekuziva.

Mhedzisiro yechidzidzo chekushushikana uye kufutisa zvakaburitswa mupepanhau PLOS YEMWE munaGunyana 2022.

Nokuda kwechidzidzo chacho, vatsvakurudzi vakaongorora muenzaniso wevakuru ve29 (vakadzi ve16 nevarume gumi nevatatu), 13 avo vaiva neBMI muhuwandu hwekufutisa uye 17 avo vaiva huremu hwemazuva ose.

Vatori vechikamu vakapedza maviri efMRI scans, imwe mushure meyakasanganiswa yemagariro uye physiological stress bvunzo.

Vatori vechikamu vakapihwa bvunzo yekupindura kumashoko anotsanangura chikafu panguva yese yekuongorora.

Muedzo uyu waisanganisira kuona kuti pfungwa dzevanhu dzakaita sei kumashoko ane chokuita nezvokudya, akadai sezvinhu zviri pabhodhi; kuti kuwedzere mhinduro yekuda muuropi, vaongorori vakabvunza vatori vechikamu kuti vafungidzire kuti chikafu chega chega chingataridzika sei, kunhuwa uye kuravira, uye kuti vaizonzwa sei kuchidya panguva iyoyo.

Vakabvunzwawo kuti vaida marii zvokudya chimwe nechimwe, uye kana vachifunga kuti vaifanira kuchiramba, kuti vaone kuti vakaita sei pakuita chisarudzo chezvokudya chimwe nechimwe.

Mhedzisiro yacho yakaratidza kuti vanhu vakuru vakafutisa vanoratidza kuita kushoma munzvimbo dzehuropi dzinotarisira kutonga kwekuziva kunyanya mukupindura kune yakakwira-calorie chikafu, senge chizi.

Chidzidzo chacho chakaratidzawo kuti kushungurudzika kunokanganisa mhinduro dzeuropi kune zvokudya

Semuenzaniso, vanhu vakafutisa vakaratidza kuwedzera activation ye orbitofrontal cortex, dunhu rinopihwa mubairo, zvichitevera bvunzo yekushushikana.

Saizvozvo, vanhu vakajairwa-huremu avo vainyanya 'kushushikana' nebvunzo yakaitwa vakaratidzawo kushoma activation yedorsolateral prefrontal cortex, nzvimbo yakakosha yehuropi yekudzora kugona.

Kunzwisisa iyo neural hwaro hwechido chekudya zvine chekuita nekushushikana kunogona kubatsira kusimudzira kweurourobehavioural kupindira kune chinangwa chekudzikisa kudyisa kunokonzerwa nekushushikana kwakanyanya.
