Sekuyisikhathi eside, inkolelo evamile ibilokhu ithi ukulandela ukudla okusekelwe ezitshalweni kusho ukuntuleka kwezakhamzimba ezifana ne-iron noma amaprotheni. Kodwa-ke, ucwaningo olusha lwamazwe ngamazwe, lapho ososayensi baseSpain bahlanganyele khona, luphikisana nalo mbono . Lolu cwaningo, olushicilelwe kumagazini i-Biology, lubukeza izifundo ezingaphezu kwekhulu futhi luphetha ngokuthi umzimba womuntu unezindlela eziguquguqukayo eziwuvumela ukuthi usebenzise izakhamzimba ezisekelwe ezitshalweni ngokugcwele.
Ucwaningo, oluholwa nguMiguel López-Moreno waseFrancisco de Vitoria University eMadrid kanye nokubambisana kukaHana Kahleova weKomiti Yodokotela Yezokwelapha Ezinomthwalo Wemfanelo, phakathi kwabanye ochwepheshe abavela eCanada, ePeru, naseSpain, luhlaziya indlela umzimba osabela ngayo ezinguqukweni zokudla eziqhubekayo. Kunokuba nje kube yindlela engenzi lutho, umzimba ulungisa izinhlelo zawo zokulawula ukuze ugcine ibhalansi yokudla, ngisho nalapho ukudla kwamakhemikhali athile kuncipha.
Ushintsho oluyisisekelo ekudleni okunempilo
Ngokwesiko, isayensi yokudla okunempilo isungule ubudlelwano obuqondile phakathi kwenani lezakhamzimba ezidliwayo kanye nokutholakala kwazo emzimbeni. Kodwa lolu cwaningo lubonisa ukuthi lo mbono ulula kakhulu . Ngokusho kwababhali, umzimba awugcini nje ngokumunca lokho okunikeziwe, kodwa kunalokho uvuselela izindlela zokubuyisela. Isibonelo, lapho umuntu enciphisa ukudla kwakhe insimbi yezilwane, amathumbu akhulisa ukusebenza kahle kokumunca insimbi esekelwe ezitshalweni, ngenxa yokulawulwa kwe-hormone i-hepcidin. Ngokufanayo, ukukhiqizwa kwangaphakathi kwe-creatine ne-carnosine kuyanda ukuze kunxephezelwe ukungenisa okuncane kwalezi zinhlanganisela, ezitholakala cishe enyameni nasezinhlanzini kuphela.
UDkt. Kahleova uveza ukuthi umzimba awusebenzi njengepayipi elilula , kodwa kunalokho ulawula izinhlelo zawo ukuze ugcine ukuqina. Lokhu kuzivumelanisa nezimo akusheshi, kodwa kwenzeka ngemva kwamasonto noma izinyanga. Eqinisweni, izimpawu zokugaya ukudla ezivame ukuvela lapho uqala ukudla okune-fiber ephezulu, njengokuqunjelwa noma igesi, zivame ukunyamalala njengoba i-microbiota yamathumbu ishintsha futhi iba ngcono ekubiliseni ama-carbohydrate ayinkimbinkimbi.
Izakhamzimba ezinhlanu ezidala imibuzo eminingi
Ukubuyekezwa kugxile ezindaweni ezinhlanu lapho ukudla okusekelwe ezitshalweni kuvame ukungabaza khona: i-iron, i-creatine kanye ne-carnosine, iphrotheni, i-fiber evundiswayo, kanye nama-polyphenols. Kuzo zonke izimo, abacwaningi bathole ubufakazi bokuthi umzimba uyazivumelanisa nezimo . Ngokuphathelene ne-iron, nakuba abantu abadla imifino bethembele ku-iron engeyona i-heme, engamuncwa kalula, izifundo zesikhathi eside zibonisa ukuthi amathumbu ayavumelana ngokumunca ingxenye ephezulu. Ngaphezu kwalokho, inani le-iron elidliwa ngabantu abadla imifino kanye nabantu abadla imifino livame ukufana noma likhulu kunele-omnivores, ngenxa yokudla ubhontshisi, okusanhlamvu okuphelele, kanye nokudla okuqinisiwe.
Ngokuphathelene ne -creatine kanye ne-carnosine , abantu abadla imifino bavame ukuba nemisipha ephansi egciniwe , kodwa bagcina ukusebenza okuvamile futhi basabela kahle ezithasiselweni. Lokhu kubonisa ukugcwala okuphansi kwesisekelo, hhayi ukuntuleka. Amaprotheni asekelwe ezitshalweni , ngakolunye uhlangothi, ahlangatshezwa kahle ngokudla okuhlelwe kahle, okugcina imisipha namandla afana nokudla okunomsoco. I-fibre evundiswayo, engase ibangele ukungakhululeki ekuqaleni, ekugcineni isetshenziswa kangcono yi-gut microbiota eguquliwe. Futhi ama-polyphenols, ama-antioxidant compounds ezitshalweni, aguqulwa amabhaktheriya amathumbu abe ama-metabolites asebenzayo kakhulu, kanye nama-vegan esikhathi eside abonisa amazinga aphezulu.
Imikhawulo yokuzivumelanisa nezimo kanye nezincomo
Kodwa-ke, abalobi baxwayisa ngokuthi leli khono lokuzivumelanisa nezimo linemingcele yalo . Izimo ezinjengokukhulelwa, ukuvuvukala okungapheli, isifo samathumbu esivuvukalayo, isifo se-celiac, noma ukungondleki kahle okukhulu kunganqoba amandla omzimba okulawula. Ngakho-ke, ukubuyekezwa kukhuthaza ukwelulekwa komuntu ngamunye, kunokunikeza isiqinisekiso esijwayelekile noma i-alamu engadingekile. UDkt. Kahleova uveza ukuthi esivivinyweni sakhe neziguli ezinesifo sikashukela sohlobo 1, ukudla okune-fiber ephezulu, okusekelwe ezitshalweni kunciphisa izidingo ze-insulin, okubonisa ukubaluleka kokuhlola impendulo yokuzivumelanisa nezimo kubantu abathola ukwelashwa.
Lolu cwaningo luphinde lufune ucwaningo lwesikhathi eside olulinganisa ukuzivumelanisa nezimo ngokuhamba kwesikhathi , kusetshenziswa ama-biomarker ahlukanisa phakathi kwempendulo yesikhashana nesimo esizinzile. Ngokusho kwabalobi, le ndlela ayisebenzi kuphela ekudleni okusekelwe ezitshalweni kodwa kunoma yiluphi ucwaningo lokudla okunempilo oluhlose ukuthola isimo sesikhathi eside kusuka kudatha yokudla yesikhathi esifushane.
Lolu cwaningo lunikeza umbono ocacile nongokoqobo wokuthi umzimba womuntu usabela kanjani ekudleni okusekelwe ezitshalweni. Kunokuba kube umthombo wokuntuleka, lokhu kudla kungafaneleka ngokuphelele uma kuhlelwe kahle, ngenxa yezindlela zokuzivumelanisa nezimo zomzimba. Kodwa-ke, kubalulekile ukucabangela izimo zomuntu ngamunye nokufuna iseluleko sochwepheshe lapho kunezimo zempilo ezingalimaza ikhono lomzimba lokuzivumelanisa nezimo. Isayensi iyaqhubeka nokuthuthuka, ichitha izinganekwane futhi inikeza izincomo ezisekelwe ebufakazini.
