Zama ukwenza ukuziva usempilweni, nokuzikhethela ukutya okufanelekileyo

Njengengcali yezengqondo, ndizama ukufunda konke endinako malunga nendlela yokuphila ekhuthaza impilo entle, kubandakanya nokutya okusempilweni. Ukuhamba kwexesha, ndiye ndanomdla ngakumbi kwimilinganiselo yokuziphatha nakwimeko yokusingqongileyo ekukhetheni ukutya. Iincwadi ezinje nge-Omnivore's Dilemma kwaye Iphekiwe , nguMichael Pollan, kunye Ukutya izilwanyana nguJonathan Safran Foer ubonelela ngokutya okuninzi kokucinga ngale ndlela.

Kutshanje, ndibukele imovie, Yintoni iMpilo , uxwebhu lophando olulandela u-Kip Anderson kumnqweno wokuqonda unxibelelwano phakathi kwezolimo kunye norhulumente kunye nendlela ezi zinto ziyichaphazela ngayo impilo yaseMelika. Ngendlela kaMichael Moore, uAnderson ujongana namagosa kwimibutho yezempilo kazwelonke, xa beza kumnika udliwanondlebe, ngokubonisa, kodwa ngokunyanisekileyo babuze imibuzo. Inye ayinike iSusan G. Komen Foundation yayisithi “siyazibuza ukuba kutheni ungenaso isilumkiso esikhulu malunga neengozi zokutya ubisi kwiwebhusayithi xa kukho unxibelelwano ngqo nomhlaza wamabele.” Inkuthazo yalo mbuzo yayiluphononongo oluthi, ngokutsho kwefilimu, lubonise “kwabasetyhini abanomhlaza wamabele, ukuhambisa into enye kuphela ngobisi ngemini kwandisa amathuba okufa sisifo iipesenti ezingama-49 kwaye bafe nakweyiphi na iipesenti ezingama-64. ” Ukuba oku kuyinyani, njengoAnderson, ndazibuza “Kutheni iziza ezinomhlaza wamabele zingafani noSusan G. Komen zingalumkisi wonke umntu ngale nto?”

Oku kwandithumela ukuba ndenze uphando kwiincwadi zenzululwazi. Ndikwazile ukusifumana isifundo ekwakusenziwa kuso noAnderson ¹ wafumanisa ukuba ulwazi alunikileyo luchanekile: kwisampulu yabasetyhini abayi-1,893 abafunyaniswe benomdlavuza webele owaqala ukulandela iminyaka eyi-11.8, xa kuthelekiswa nabo batya ixesha elingaphantsi kwesiqingatha sosuku lokutya okunamafutha aphezulu, Ubisi, itshizi, iidisethi zederi, kunye neyogathi, abo batya izixa eziphezulu babenamazinga aphezulu kakhulu okusweleka komhlaza wamabele, konke oku kubangela ukusweleka, kunye nokufa komhlaza webele ongengowamabele. Nangona kunjalo, ezinye iziphumo ezivela kuphononongo zibonise ukuba ukutya okunobisi olunamafutha asezantsi bekukho ngokungafaniyo ezinxulumene nezi ziphumo zokufa kuhlalutyo oluhlengahlengisiweyo oluncinci (apho ubudala kunye nexesha phakathi kokuchongwa komhlaza wamabele kunye nokuvavanywa kokungeniswa kobisi kwakulawulwa) kwaye kungahambelani nezi ziphumo kuhlalutyo oluhlengahlengisiweyo lwezinye izinto ezibalulekileyo (ezinje ngobungqongqo besifo; uhlobo unyango lomhlaza; inqanaba lemfundo; ubuhlanga; ukutya kweekhalori, inyama ebomvu, utywala, ifayibha, kunye neziqhamo; ubunzima bomzimba; amanqanaba omsebenzi womzimba; kunye nenqanaba lokutshaya). Ngokufanayo, ukusetyenziswa kobisi ngokubanzi kwakuhambelana kuphela nokusweleka kwabantu ngokubanzi kuhlalutyo oluhlengahlengisiweyo. Ukuphindaphinda komhlaza webele kwakungahambelani nokutya ubisi (amanqatha asezantsi, amanqatha aphezulu, okanye iyonke) kuhlalutyo oluhlengahlengisiweyo okanye olungalunganga. Ke, umfanekiso wam waba mnyama ngakumbi.

Ababhali banikezele ngesizathu sokunyanzelwa konxibelelwano phakathi kokutya amanqatha obisi, amanqanaba e-estrogen, kunye neziganeko kunye nokuqhubela phambili komhlaza onxulumene neehomoni ezinje ngesifuba, i-ovari, i-postmenopausal endometrial, kunye neprostate, kodwa baqaphela ukuba olunye uphononongo lufumanise ukuba iphantsi- ukuthathwa kobisi olunamafutha kwakudityaniswa nomhlaza wedlala lobudoda. Abanye abaphandi bathi iihomoni zesini sabasetyhini zinokuba likhonkco phakathi kokusetyenziswa kobisi kunye nomhlaza onxulumene nehomoni ngakumbi kuba ubisi esilusebenzisayo namhlanje, ngokwahlukileyo kwiminyaka eyi-100 eyadlulayo, luvela kwiinkomo ezikhulelweyo eziphakamise amanqanaba ehomoni. ²

Ukufumana ukucaca okuthile, endaweni yokugxila kwizifundo ezizodwa ngokubhekisele kwikhonkco phakathi kokusetyenziswa kweemveliso zobisi kunye nomhlaza wamabele, ndaye ndadibana nokujonga ngokubanzi uncwadi lophando, ngakumbi uphononongo olucwangcisiweyo kunye nohlalutyo lweemeta. Inye, ichazwe njengovavanyo lwenqobo yobungqina bobunzululwazi, ixele ukuba ikhonkco ekusetyenzisweni kweemveliso zobisi kunye nomngcipheko wesifo somhlaza wamabele awunakulinganiswa okanye uguqukile, mhlawumbi ngenxa yeziphumo zokukhusela i-calcium kunye nevithamin D. ³ Ababhali baqukumbele ngelithi “ukutya ubisi kunye neemveliso zobisi kunegalelo ekuhlangabezaneni neengcebiso zezondlo kwaye kunokukhusela kwizifo ezixhaphakileyo, ezinganyangekiyo ezingasuleliyo, ngelixa zimbalwa iziphumo ezibi ezichaziweyo.” Ukuxelwa kwababhali, nangona kunjalo, kuluhlu lwenkxaso evela kwimibutho emininzi yedayari, enje ngeZiko loPhando ngeDeri, iDanish Dairy Research Foundation, kunye nePlatform yeDeri yeHlabathi, phakathi kwabanye. Oku kulandelwe nesibhengezo, kuba babini kuphela kwabahlanu ababhali abafumene le nkxaso, yokuba abaxhasi abanandima bayilayo kunye nokuziphatha komsebenzi wabo wangaphambili. Uhlalutyo lweemeta lwezifundo ezinokubakho alufumanisanga unxibelelwano olulinganayo phakathi kobisi olupheleleyo, ubisi olupheleleyo, kunye nokusetyenziswa kweyogathi kunye nomngcipheko womhlaza webele kwaye lafumana unxibelelwano phakathi kokusetyenziswa kobisi oluncitshisiweyo kunye nokwehla komngcipheko womhlaza webele. Ababhali bolu phononongo, nangona kunjalo, khange baxele nayiphi na inkxaso kumzi mveliso wobisi. ⁴

Iziphumo ezixubeneyo kunye nokuzibandakanya kumzi mveliso kubonakalisa ubunzima bokucoca izigqibo eziqinisekileyo malunga nokutya okusempilweni, kwanakwimithombo yesayensi enegunya. Ngelixa ndiqhubeka nokuzama ukunciphisa ukusetyenziswa kwam kweemveliso zezilwanyana ngenxa yezizathu zokuziphatha, uphononongo lwam loncwadi lwenzululwazi ngalo mbandela luzise imibuzo emininzi kuneempendulo.
