Lapho ehlola ingozi yesifo sikashukela, amaqembu amabili odokotela base-United States bathola into engazange ilale kule ndawo. Bathole ukuthi ukudla okunhlobonhlobo kuyimbangela yokukhuluphala. Ngenxa yalokho, ukuzuza kwesisindo kunamandla kakhulu kunokungenzi lutho okuhambisana nendlela yokuphila yokunganyakazi. Udaba lwasingathwa kanye nje amaqembu amabili ezokwelapha - avela eNyuvesi yaseTexas naseNyuvesi yaseTufts.
Bethule umbiko wabo kumagazini i-PLOS ONE. Kulandela ukuthi ucwaningo lwenziwa kusukela ngo-2000 futhi luhlanganisa amavolontiya ayizinkulungwane ezingu-6,8 anikezwa ukudla okuhlukile. Imenyu yeminye yayihlanganisa imikhiqizo eyahlukene, kuyilapho isilinganiso seminye sasihlanganisa uhlu oluthile lokudla. Iminyaka eyishumi nanhlanu, abahlanganyeli banamathela ekudleni. Khona-ke ososayensi bafingqa. Wabonisa ukuthi izitsha ezihlukene kakhulu kumenyu yabantu, ingozi enkulu yokuthola amakhilogremu engeziwe. Ukuxhumana okunjalo, ngokusho kososayensi, kumane kuchazeke. Imetabolism yomuntu ihlushwa ukudla okuhlukahlukene… Lokhu kubonakala ekushintsheni kwamazinga eglucose egazini kanye nokwenyuka komfutho wegazi.
Ukucekelwa phansi kwempilo kubhebhethekiswa isethi yamaphawundi engeziwe afakwa endaweni ye-peritoneal. Ngisho nasesimweni lapho imikhiqizo ehlukahlukene, ngaphandle kokukhetha, ingeyesigaba esibalulekile empilweni yomuntu. Ngokuphathelene nedatha etholiwe, ososayensi banxusa ukunciphisa inani lezitsha ezihlukahlukene, bekhumbula ukuthi imenyu ecebile ngezibiliboco iyingozi kakhulu empilweni yomuntu kunempilo yokuphila.
