Ushizi oluhlaza awenzelwe ulwanga lwawo wonke umuntu. Bambalwa abathola ukunambitheka okuqinile kukashizi onesikhunta kumnandi, futhi lokhu kungase kube ngenxa yokuguqulwa kofuzo.
Uma i-gorgonzola ibonakala ngathi inokunambitheka kwensipho, ucwaningo lwakamuva luphakamisa ukuthi kungenxa yezakhi zofuzo ezine ezibalulekile ezithinta ukunambitheka koshizi oluhlaza okwesibhakabhaka. Enye yalezi zakhi zofuzo, i-STY9, itholakala eduze nesakhi sofuzo se-cilantro ku-chromosome 11, okutholwe ukuthi inesibopho kumuntu oyedwa kwabahlanu ozwa iphunga elifana nelokuhlanza lapho edla i-cilantro. Ezinye zihlanganisa i-PDE4B, i-AVL9, ne-HTR1B.
Kungani ushizi oluhlaza unambitheka njengensipho?
Kungenzeka asikaze sikubone, kodwa kukhona abazwa ukunambitheka kwensipho lapho bedla lolu hlobo lukashizi. Abacwaningi bocwaningo benze ucwaningo kubantu abangu-219 abaneminyaka engu-18 kuya ku-77. Bathola ukuthi izingxenye ezimbili kwezintathu zathi okungenani uhlobo olulodwa lwe-gorgonzola lunambitheka njengensipho kubo.
Lesi sibalo sabantu abathakazelelwa insipho siphezulu kakhulu futhi siyamangaza. Abahlanganyeli bacelwe ukuthi banambithe futhi bachaze izinhlobo eziyisithupha ezihlukene zikashizi, ezenziwe ngobisi lwenkomo olunga-skimmed. Abacwaningi baphinde bahlaziya i-DNA yalabo ababehileleke ocwaningweni ngomzamo wokuthola ukuthi yiziphi izakhi zofuzo ezazivamile kulabo abangawuthandi ushizi nokuthi ingabe lezi yizo ezazibangela ukunambitheka kwawo.
Umsebenzi wabo uphakamisa izakhi zofuzo zamakhandidethi ezingase zihlotshaniswe nombono wokunambitheka okunensipho, okuhlinzeka ngesiqalo sokuqonda kangcono umehluko ngamunye ekubonweni kukashizi oluhlaza okwesibhakabhaka. Okokuqala, umbono wokunambitha "okunensipho" kushizi weGorgonzola watholakala uhlotshaniswa nabanye ukuhlukahluka kofuzo (njengoba kubonwe ngaphambilini kokunye ukudla, njenge-cilantro).
Eqinisweni, lo msebenzi uphakamise izinhlobo ezine zekhandidethi ezingase zibe khona (SYT9, PDE4B, AVL9 kanye ne-HTR1B), ezibandakanyeka ezinqubweni zokuhogela noma ezithinta inhliziyo, ezihambisana nokubonwa kokunambitheka kwensipho. I-locus eyaziwa kakade ku-chromosome 11 yombono wensipho ku-cilantro nayo yaqinisekiswa kancane.
Abacwaningi bathola ukuthi abantu abangu-144 kwabangu-219 ababambe iqhaza ocwaningweni (amaphesenti angu-65,8) baphawule ukunambitheka okunensipho okungenani ohlotsheni olulodwa lukashizi oluhlaza okwesibhakabhaka. Isamba esingu-25,1% sibe nomuzwa esiqeshini esisodwa se-gorgonzola, 21,9% kumasampuli amabili, 8,2% kwamathathu, 3,2% kwamane, 2,7% amahlanu kanye 4,6% koshizi abayisithupha.
Futhi ushizi we-cheddar
Ngokuzayo, ulwazi lwezinhlobonhlobo zofuzo ezihlobene nokuthandwayo kokudla lungasiza ekuthuthukiseni amasu amasha okukhuthaza impilo yabathengi kanye nokuvimbela izifo ezihlobene nokudla.
Enye indlela yocwaningo lwangomuso kungaba ukugxilisa ucwaningo eqenjini labantu elihlanganisa nenani elikhulu lezihlobo. Ngale ndlela, ukutholakala kwefa lokutholwa kokunambitheka kwensipho kushizi we-gorgonzola kungalinganiselwa. Ngaphezu kwalokho, ucwaningo lunganwetshwa kwezinye izishizi eziluhlaza okwesibhakabhaka (njenge-Roquefort ne-Stilton cheeses) kanye nezinhlobo ezichazwe ngaphambilini zikashizi ezinokunambitheka okunensipho (njengoshizi we-cheddar).
Ngakho noma kuhle udle ushizi ngokujwayelekileMhlawumbe esikuthandayo kuphawulwa ngezakhi zofuzo.
