Umxholo

Nokuba unenkxalabo malunga nenkohlakalo yezilwanyana okanye awuyithandi nje incasa yenyama, isigqibo sokuba ngumlimi (okanye nokuba ngumlimi kuphela weveki) uziva ngathi sisigqibo nje. Kodwa isifundo esitsha sipapashwe kwi- Ijenali yeBhayoloji yeMolekyuli uthi unokuba nolawulo oluninzi kwindlela otya ngayo kunokuba ubucinga. Abaphandi bafumanise ukwahluka kwemfuza ekubonakala ukuba kwavela kubemi abathanda izidlo zemifuno ngaphezulu kwamakhulu ezizukulwana, kubandakanya nezo e-India, e-Afrika, nakwiindawo ze-East Asia, zonke ezinokutya okufana "nokuhlaza" namhlanje. (Jonga Izizathu ezili-12 zokutya kwemifuno yinto elungileyo.)

I-Kaixiong Ye yeYunivesithi yaseCornell kunye noogxa bakhe bajonga ukuxhaphaka kwe-allele (igama lokutshintsha kwemfuzo) eyayidityaniswe nemifuno kubantu abangama-234 abavela eIndiya kunye nabantu abangama-311 base-US ababengadli imifuno. Bafumene umahluko kuma-68 eepesenti amaIndiya nakuma-18 eepesenti kuphela abantu baseMelika. Oku kuqhubela phambili inkcazo-bungcali yokuba ngabantu abahlala kwiinkcubeko eziphila ngokutya okusekelwe kwizityalo kwaye kunokwenzeka ukuba baphathe i-allele yemifuno. Abantu baseMelika bahlala besitya izinto ezenziweyo-esinye isifundo sipapashiwe BMJ vula ifumanise ukuba ngaphezulu kweepesenti ezingama-57 zokutya kwabemi base-U.S. kwenziwe ukutya "okuqhubekeke ngokugqithileyo". (Ngaba kufanelekile ukuthiya ukutya okucwangcisiweyo?)


Okubangela umdla kukuba, loo allele ivumela abantu abanayo ukuba "baqhube kakuhle i-omega-3 kunye ne-omega-6 fatty acids kwaye baziguqule zibe ziikhompawundi eziyimfuneko ekuphuhlisweni kobuchopho kwangaphambili," utshilo uYe kwingxelo. I-Omega-3 fatty acids ngamafutha asempilweni afumaneka kwiintlanzi ezifana nesalmon yasendle; I-omega-6s ifumaneka kwinyama yenkomo kunye nehagu. Inani elingonelanga kuzo zombini i-omega-3s kunye ne-omega-6s zikubeka emngciphekweni omkhulu wokudumba okanye isifo sentliziyo, umngcipheko othile kubantu abatya inyama. Kwaye ngenxa yokunqongophala kwe-omega-3s kunye ne-omega-6s ekutyeni kwabo, kuye kwathiwa abantu abatya imifuno banemiba yokwetyisa ngokufanelekileyo. Olu phononongo bubungqina bokuba le allele inokuba yavela ukwenza loo nkqubo ibe lula kubo.

Iziphumo zophando zikhuthaza umxholo wesondlo esenzelwe umntu, utshilo. "Singalusebenzisa olu lwazi lwe-genomic ukuzama ukulungelelanisa ukutya kwethu ukuze ihambelane ne-genome yethu," ucacisile kwingxelo yakhe. Emva kwayo yonke loo nto, akukho nto inje ngokutya okulinganayo. Ngaba uyafuna ukuziqhelanisa nenkqubo yakho yokutya? Landelela ukutya kwakho kwaye umamele umzimba wakho. (Nantsi indlela yokwenza umsebenzi weJenali yokuTya ngokutya.) Isisu esigexayo emva kwesidlo sasemini kuthetha ukuba lixesha lokuphosa i-turkey burger kwaye mhlawumbi ukhethe ukugoba i-veggie ngexesha elizayo, endaweni yoko.
