Ukudla inyama kuyingozi empilweni. Maphakathi no-Agasti, umkhuba wokufafaza amagciwane aphilayo emikhiqizweni yenyama wamukelwa ngokusemthethweni. Isifutho senkampani yaseBaltimore sibizwa nge-Intralytix, equkethe izinhlobo eziyisithupha zegciwane eziklanyelwe ukubulala i-listeriosis. Izinkampani zenyama azidingeki ukuthi zazise abathengi ukuthi yikuphi ukudla okucutshunguliwe nokuthi yikuphi okungakalungiswa. Emashumini eminyaka adlule, safunda ukuthi amafutha atholakala enyameni andisa inani le-cholesterol egazini labathengi. Futhi lokho kuholela ekuhlaselweni yinhliziyo. Ngakho-ke, odokotela baseluleka ukuba sinciphise ukusetshenziswa kwenyama futhi sicebise ukudla ngemifino. Ngesikhathi esifanayo, kwavela umqondo we "carcinogens". Inyama eyosiwe idala umdlavuza. Amakhemikhali abizwa ngokuthi i-heterocyclic amines akha phezu kwenyama, ku-crust crispy. Kungenxa yalolu qweqwe ukuthi ukwanda komdlavuza kubantu abadla inyama. Inkukhu, njengoba kuvela, ikhiqiza ama-carcinogens amaningi kakhulu kunenyama yenkomo. Kuthiwani uma ubilisa inkukhu? Ucwaningo luye lwabonisa ukuthi i-mercury, ezinye izinsimbi ezisindayo, nezibulala-zinambuzane ezihlukahlukene kuningi ezicutshini zezilwane. Ngikhumbula ukuthi izinhlanzi zamenyezelwa kanjani ngokusemthethweni njengephupho elibi kakhulu: izinhlangano zikahulumeni kanye nezifundazwe zakhipha izixwayiso eziqinile, izinhlanzi ziyingozi ikakhulukazi ezinganeni nakwabesifazane abaneminyaka yobudala yokuzala. Base beqala ukukhuluma ngama-microbe enyameni. I-Salmonella kanye neCampylobacter kumenyezelwe ukuthi banecala ezinkulungwaneni zamacala unyaka ngamunye. Usongo lwamagciwane lwafinyelela izinga elisha lapho i-E. coli iholela ochungechungeni lokufa phakathi kwabadla ama-hamburger. Laba kanye nabanye abahlaseli abayingozi bavame ukushaya inyama yenkomo, izinkukhu namagobolondo. Futhi izinhlangano zikahulumeni zisebenzisa izigidi zamarandi zizama ukunqanda ubukhulu benkinga. Okuqhubekayo - kubi kakhulu. Isifo se-Mad cow saqala eYurophu futhi siye sabonwa ngezikhathi ezithile ezinkomeni zaseNyakatho Melika. Ayibangelwanga amafutha, amagciwane, noma amagciwane, kodwa yayibangelwa uhlobo oluthile lwamaprotheni olwaziwa ngokuthi i-prion. Izikhulu zikahulumeni nezimboni zisebenzisa izigidi ekuhloleni, futhi odokotela bezinzwa bafunda ubudlelwano phakathi kwesifo senkomo esihlanyayo kanye nezinhlobo ezingavamile zokuwohloka komqondo. Khonamanjalo, ososayensi bangase baqaphele ukuthi i-asparagus nesitshalo seqanda awabangeli amarabi kanye nokusangana. Ukotapheya awuwutholi umkhuhlane, futhi nomkhuhlane wama-strawberry awukho. Kodwa umkhuhlane wezinyoni wavela njengobhubhane olungase lube khona. Izinyoni zingenwa kalula amagciwane, njengezinye izilwane. Ngokuvamile aziyona ingozi kubantu. Kodwa umphakathi wethu uthanda izinyoni kakhulu—manje amaMelika adla izinkukhu ezingaphezu kwesigidi ngehora—futhi lokho kusho ukuthi izinkukhu, amaturkey nezinye izinyoni zifuyelwa inyama. Uma igciwane le-H5N1 selihlala epulazini lezinkukhu, lisakazeka ngokushesha.
Futhi manje, ukuze kubulawe amanye amagciwane aphuma ethunjini lesilwane kanye nomhlaba ocezwini lwenyama enamafutha agcwele kanye ne-cholesterol, abantu baye bacabanga ukufafaza inyama ngamagciwane. Isikhathi sokuvuka futhi unuke inkinga. Izigidi zabantu baseMelika manje azinayo inyama. Lapho bekwenza, amazinga e-cholesterol abo ehla. Imithambo yenhliziyo yabo yavuleka futhi. Isisindo sabo siyehla, futhi amathuba abo okuba nomdlavuza ancipha ngamaphesenti angu-40. Ukudla okunempilo kwemifino kungavuselela impilo yesizwe. U-Neil D. Barnard, MD, umcwaningi wokudla okunomsoco kanye nomongameli weKomidi Lodokotela Lomsebenzi Wokwelapha.
