Unogona kugutsa nzara nechinenge chero chikafu, asi kushuva chimwe chinhu kunyanya kunogona kutigadzirisa pane chimwe chigadzirwa kusvikira tazokwanisa kuchidya.
Vazhinji vedu tinoziva zvazvinoita kuva nechikafu chekudya. Kazhinji, kushuva kunoitika kune-high-calorie foods, saka ivo vanobatanidzwa nekurema uye kuwedzera kwehuwandu hwemuviri.
Zvinotendwa nevakawanda kuti chido chekudya inzira yemuviri wedu inotiratidza kuti tiri kushayikwa mune chimwe chikafu chinovaka muviri, uye kana vari vakadzi vane pamuviri, izvo zvishuwo zviri kuratidza izvo mwana anoda. Asi ndizvo chaizvo here?
Tsvagiridzo zhinji yakaratidza kuti kuchiva kwechikafu kunogona kuve nezvikonzero zvakawanda - uye zvakanyanya zvepfungwa.

Mukutanga kwema1900, musayendisiti wokuRussia Ivan Pavlov akaziva kuti imbwa dzinomirira kurapwa mukupindura kune zvimwe zvinokurudzira zvine chokuita nenguva yekudya. Muchikamu chekuedza kwakakurumbira, Pavlov akadzidzisa imbwa kuti kurira kwebhero kwaireva nguva yekudya.
Sekureva kwaJohn Apolzan, mubatsiri purofesa wezvekudya kwekiriniki uye metabolism paPennington Center yeBiomedical Research, zvishuwo zvakawanda zvekudya zvinogona kutsanangurwa nenharaunda yauri.
“Kana ukagara uchidya mapopcorn paunotanga kuona purogiramu yeTV yaunofarira, havi yako inowanda paunotanga kuiona,” anodaro.
Anna Konova, mutungamiriri weAdiction and Decision Neuroscience Laboratory paRutgers University muNew Jersey, anoti kuda kutapira kwepakati pezuva kunowanzoitika kana uri kubasa.
Nokudaro, kuchiva kunowanzokonzerwa nezvimwe zvinhu zvokunze, kwete nokuti muviri wedu uri kuda chimwe chinhu.
Chocolate ndechimwe chezvishuwo zvakajairika kuMadokero, izvo zvinotsigira nharo yekuti zvishuwo hazvikonzerwi nekushomeka kwekudya, sezvo chokoreti isina huwandu hwakawanda hweizvo zvinovaka muviri zvatingave tisina.
Zvinowanzopokana kuti chokoreti chinhu chakajairika chinodiwa nekuti chine huwandu hwakawanda hwe phenylethylamine, molecule inoratidza uropi kuburitsa makemikari anobatsira dopamine uye serotonin. Asi zvimwe zvikafu zvakawanda zvatisingadi kazhinji, kusanganisira mukaka, zvine huwandu hwepamusoro hwemorekuru uyu. Zvakare, kana tichidya chokoreti, ma enzymes anoputsa phenylethylamine kuitira kuti isapinde muuropi muhuwandu hwakakosha.
Zvidzidzo zvakawana kuti vakadzi vane mukana wakapetwa kaviri wekushuva chokoreti sevarume, uye kazhinji izvi zvinoitika pamberi uye panguva yekuenda kumwedzi. Uye nepo kurasikirwa kweropa kuchigona kuwedzera njodzi yehumwe kushaya kudya kunovaka muviri, kwakadai sesimbi, masayendisiti anocherekedza kuti chokoreti haidzore mazinga esimbi nekukurumidza senyama tsvuku kana mashizha ane rima.
Mumwe angafungidzira kuti kana paine chero yakananga mahomoni mhedzisiro inokonzera biological kuda chokoreti panguva kana pamberi pekuenda kumwedzi, chido ichocho chaizodzikira mushure mekuenda kumwedzi. Asi imwe ongororo yakawana kuderera kudiki chete mukuwanda kwechishuwo chechokoreti muvakadzi vepomenopausal.
Zvinonyanya kuitika kuti kubatana pakati pePMS uye chokoreti chido chetsika. Imwe ongororo yakawana kuti vakadzi vakaberekerwa kunze kweUS vaive vashoma mukana wekubatanidza zvishuwo zvechokoreti nekuenda kwavo kumwedzi uye vane ruzivo rwechokoreti ruchiva zvishoma kazhinji kana vachienzaniswa nevakazvarwa muUS uye chizvarwa chechipiri vanobva kune dzimwe nyika.
Vatsvakurudzi vanopikisa kuti vakadzi vanogona kubatanidza chokoreti nekuenda kumwedzi nokuti vanotenda kuti zvinogamuchirwa netsika kuti vadye "zvakarambidzwa" zvokudya panguva uye vasati vasvika. Maererano navo, kune "kunakisisa" kwerunako rwechikadzi mutsika dzekuMadokero izvo zvinopa pfungwa yekuti chido chakasimba chechokoreti chinofanira kuva nechikonzero chakasimba.
Chimwe chinyorwa chinopokana kuti kushuva kwechikafu kunobatanidzwa nemanzwiro ambivalent kana kukakavara pakati pechido chekudya uye chido chekudzora kudya. Izvi zvinogadzira mamiriro ezvinhu akaoma, sezvo zvishuvo zvakasimba zvekudya zvinokurudzirwa nemanzwiro asina kunaka.
Kana avo vanozviganhurira vamene kuzvokudya kuti vaderedze uremu vachigutsa zvishuvo nokudya zvokudya zvinoshuviwa, vanonzwa vakashata nemhaka yokufunga kuti vakaputsa mutemo wezvokudya.
Zvinozivikanwa kubva mukutsvagisa uye kukiriniki kucherechedzwa kuti manzwiro asina kunaka anogona kungowedzera kudya kwemunhu uye kunyange kumutsa kudyisa. Iyi modhi ine chekuita nekudiwa kwebiological kwechikafu kana nzara yemuviri. Asi, mitemo yatinoita pamusoro pezvokudya uye migumisiro yokuityora.
Tsvagiridzo inoratidzawo kuti kunyangwe kupindwa muropa nechokoreti kwakajairika kuMadokero, haina kutomboitika munyika zhinji dzekuMabvazuva. Kunewo misiyano mukuti zvinotendwa pamusoro pezvokudya zvakasiyana-siyana zvinotaurirwa uye zvinonzwisiswa sei—zvikamu zviviri kubva muzvitatu chete zvemitauro zvine shoko rokuchiva, uye kazhinji kazhinji shoko iroro rinongoreva zvinodhaka, kwete zvokudya.
Kunyangwe mumitauro iyoyo ine analogues ezwi rekuti "kuda", hapasati pave nekubvumirana pane izvo. Konova anopokana kuti izvi zvinotadzisa kunzwisisa nzira yekukunda zvishuwo, sezvo tichigona kunyora akati wandei maitiro sezvido.
Kushandisa ma microbes
Pane humbowo hunoratidza kuti mabhirioni emabhakitiriya ari mumiviri yedu anogona kutinyengedza kuti tide uye tidye zvavanoda—uye handizvo zvinodiwa nomuviri wedu nguva dzose.
“Microbes inotarisira zvido zvavo. Uye vanozvigona,” anodaro Athena Aktipis, mutevedzeri wapurofesa wepfungwa paArizona State University.
“Matumbu emudumbu, ayo anorarama zvakanyanya mumuviri wemunhu, anowedzera kusimba nechizvarwa chitsva chega chega. Vane mukana wekushanduka-shanduka wekuti vanokwanisa kutifurira zvakanyanya kuti tivadyise zvinoenderana nezvavanoda,” anodaro.
Hutachiona hwakasiyana mumatumbo edu hunosarudza nharaunda dzakasiyana-yakawanda kana shoma acidic, semuenzaniso-uye izvo zvatinodya zvinokanganisa ecosystem mumatumbo uye mamiriro ayo mabhakitiriya anogara. Vanogona kutiita kuti tidye zvavanoda nenzira dzakasiyana-siyana.
Vanogona kutumira masaini kubva muura kuenda kuuropi kuburikidza neyedu vagus nerve uye kutiita kuti tinzwe takashata kana tikasadya zvakakwana zvechimwe chinhu, kana kutiita kuti tinzwe zvakanaka patinodya zvavanoda nekuburitsa neurotransmitters se dopamine. uye serotonin. Vanogonawo kuita pakuravira kwedu kuitira kuti tidye zvakawanda zvechimwe chikafu.
Masayendisiti haasati akwanisa kutora maitiro aya, Actipis anodaro, asi pfungwa yacho yakavakirwa pakunzwisisa kwavo maitiro ehutachiona.
"Pane maonero ekuti microbiome chikamu chedu, asi kana uine chirwere chinotapukira, hongu iwe uchati hutachiona hunorwisa muviri wako, uye hausi chikamu chayo," anodaro Aktipis. "Muviri wako unogona kutorwa neakaipa microbiome."
"Asi kana iwe ukadya chikafu chakakwira mune yakaoma makabhohaidhiretsi uye faibha, iwe uchave neyakasiyana microbiome mumuviri wako," Aktipis anodaro. "Kana zvakadaro, kuita kweketani kunofanirwa kutanga: chikafu chine hutano chinobereka ine hutano microbiome, izvo zvinoita kuti iwe ushuve chikafu chine hutano."

Hupenyu hwedu hwakazara nezvinhu zvinokonzeresa zvekudya, senge masocial media ads uye mapikicha, uye hazvisi nyore kuzvidzivisa.
“Kwese kwatinoenda, tinoona kushambadzwa kwezvigadzirwa zvine shuga yakawanda, uye zvinogara zviri nyore kuwana. Uku kurwiswa kwekushambadzira kunogara kuchikanganisa huropi - uye kunhuhwirira kwezvigadzirwa izvi kunokonzera kuvashuvira, "anodaro Avena.
Sezvo mararamiro emudhorobha asingatenderi kudzivirira zvese izvi zvinokonzeresa, vaongorori vari kudzidza kuti tingakunda sei chimiro chekuda chishuwo tichishandisa nzira dzekuziva.
Tsvakurudzo dzinoverengeka dzakaratidza kuti nzira dzekudzidzisa kutarisisa, sekuziva zvishuwo uye kudzivisa kutonga iyo mifungo, inogona kubatsira kuderedza kushuva zvachose.
Kutsvakurudza kwakaratidza kuti imwe yenzira dzakanakisisa dzekudzivisa kushuva ndeyekubvisa zvokudya zvinokonzera kushuva kubva pakudya kwedu-kupesana nekufungidzira kuti tinoshuva izvo muviri wedu unoda.
Vatsvakurudzi vakaita muyedzo wemakore maviri umo vakaraira mumwe nemumwe wevatori vechikamu mazana matatu chimwe chezvokudya zvina zvine mazinga akasiyana emafuta, mapuroteni, uye makabhohaidhiretsi uye akayera zvido zvavo zvekudya uye kudya.

Vatsvakurudzi vanoti kuderedza chido, vanhu vanofanira kungodya zvokudya zvavanoda zvishoma, zvichida nokuti ndangariro dzedu dzezvokudya izvozvo dzinopera nekufamba kwenguva.
Pakazere, masayendisiti anobvuma kuti kutsvagisa kwakawanda kunodiwa kutsanangura nekunzwisisa zvishuwo uye kugadzira nzira dzekukunda mhinduro dzakamisikidzwa dzine chekuita nekudya zvisina hutano.
