Ingabe Ungahlelwa Ngofuzo Ukuze Ube Ongadla Imifino?

Noma ngabe unokhathazeka ngesihluku sezilwane noma umane nje awuthandi ukunambitheka kwenyama, isinqumo sokuba ngumuntu odla imifino (noma ngisho nosuku lwemifino kuphela phakathi nesonto) sizwakala njengaleso-isinqumo. Kepha isifundo esisha esishicilelwe kufayela le- Ijenali ye-Molecular Biology uthi ungase ukwazi ukulawula indlela odla ngayo kunalokho obukucabanga. Abacwaningi bathola ukwehluka kwezakhi zofuzo okubonakala sengathi kuye kwavela kubantu abaye bathanda ukudla kwemifino ngaphezu kwamakhulu ezizukulwane, kuhlanganise nalezo zaseNdiya, e-Afrika, nasezingxenyeni zaseMpumalanga Asia, zonke ezinokudla okufanayo "okuluhlaza" namuhla. (Bheka Izizathu Ezingu-12 Zokudla Kwemifino Kungumbono Omuhle.)

U-Kaixiong Ye wase-Cornell University kanye nozakwabo babheke ukusabalala kwe-allele (igama elisho ukuhlukahluka kofuzo) elalixhunywe nokudla kwemifino kubantu abangu-234 abavela e-India kanye nabantu abangu-311 base-U.S. ababengadli imifino. Bathola ukuhluka ngamaphesenti angama-68 amaNdiya kanye namaphesenti angu-18 kuphela aseMelika. Lokhu kuqhubekisela phambili umbono wokuthi ngabantu abahlala emasikweni abaphila ngokudla okusekelwe ezitshalweni okungenzeka ukuthi baphathe i-allele yemifino. Abantu baseMelika bavame ukudla okuningi kwezinto ezicutshunguliwe-olunye ucwaningo olushicilelwe kulo BMJ Vula ithole ukuthi ngaphezu kwamaphesenti angama-57 okudla kwabantu base-U.S. akhiwe ngokudla "okwenziwe nge-ultra-processed". (Ingabe kufanele ukuzonde ngempela ukudla okugayiwe?)

Kuyathakazelisa ukuthi leyo allele ivumela abantu abanayo ukuthi "bacubungule kahle i-omega-3 ne-omega-6 fatty acids futhi bawaguqule abe yizinhlanganisela ezibalulekile ekuthuthukisweni kobuchopho kwasekuqaleni," kusho u-Ye esitatimendeni. Ama-omega-3 fatty acids amafutha anempilo enhliziyo atholakala ezinhlanzini njenge-salmon yasendle; Ama-omega-6 atholakala enkomeni yenkomo nengulube. Inani elinganele lakho kokubili i-omega-3s kanye ne-omega-6s likubekela engozini enkulu yokuvuvukala noma ngisho nesifo senhliziyo, ingozi ethile kwabadla imifino. Futhi ngenxa yokuntuleka kwe-omega-3s kanye ne-omega-6s ekudleni kwabo, kuthiwa abantu abadla imifino banezinkinga zokuwagaya ngendlela efanele. Lolu cwaningo luwubufakazi bokuthi le allele kungenzeka ukuthi yavela ukwenza leyo nqubo ibe lula kubo.

Imiphumela yocwaningo ikhuthaza umqondo wokudla okunomuntu uqobo, kusho uYe. "Singasebenzisa lolu lwazi lwe-genomic ukuzama ukuvumelanisa indlela esidla ngayo ukuze ihambisane ne-genome yethu," echaza esitatimendeni sakhe. Ngemuva kwakho konke, ayikho into enjengokudla okukodwa okulingana nosayizi owodwa. Ufuna ukusebenzisa lo mkhuba ohlelweni lwakho lokudla? Landelela ukudla kwakho futhi ulalele umzimba wakho. (Nansi Indlela Yokwenza Umsebenzi Wokushicilela Ukudla Kukusebenzele.) Isisu esixakayo ngemuva kwesidlo sasemini sisho ukuthi sekuyisikhathi sokuphonsa i-turkey burger futhi mhlawumbe ukhethe okugoqiwe kwe-veggie ngokuzayo, esikhundleni salokho.
