Ukungafani, ngokuphathelene ne-egg-yolk-yolk
Ezingxenyeni zezwe, amaqanda ahlolwa, ikakhulukazi, amaprotheni kanye ne-yolk ngokwehlukana. I-relative zhezhetka yembulwa ukuthi kuleso sikhala se-cholesterol kusukela ku-215 kuya ku-275 milligram. Kwakukhona ukuqhathaniswa okufana nokudla kokudla okusheshayo. Ngakho-ke, kwavela ukuthi ama-rolls kanye nama-chops, noma ama-hamburger aqukethe kuwo amakhologremu ayikhulu namashumi amahlanu we-cholesterol. Ngakho-ke, uma abantu besengozini yesifo senhliziyo, i-yolk idinga ukuthathwa ngokuqapha okungavamile, kusukela ngosuku abakhuthazwa ngayo ukuba badle ukudla okuqukethe ama-milligram ama-cholesterol angaphezu kwamakhulu amabili. Iqembu eliyingozi lihlanganisa nezifo ezinjalo, ezicasuliwe futhi zihlaselwe yizinga eliphezulu le-cholesterol.

Futhi ngalesi sikhathi, i-cholesterol iyasiza, "ukunamathela" ezindaweni eziyinkimbinkimbi. Izitsha zingase ziqale ukunciphisa - kodwa lokhu kuyinkomba kuphela yokuthi kunezinye iziphambano emzimbeni, kodwa akukho nhlobo i-cholesterol lapha. Umzimba womuntu uyisistimu eyanele ngokwanele ekwazi ukuvuselelwa ksamo, kuya kokugcina. Kodwa abantu bavame ukubhekisela kuye ngokuphelele kabi. Futhi i-cholesterol ngokweqile yenziwa egazini nhlobo ngenxa yokudla ngokweqile ukudla okunamafutha noma izikhupha zezinkukhu. Lokhu kungase kwenzeke ngenxa yokungondleki, hhayi ukulinganisela.
Kungenzeka ukuthi esikhathini esizayo esiseduze isimo sengqondo sokuthi amaqanda azoshintsha futhi bazofaka ukudla okuvamile. Sizowasebenzisa kaningi kakhulu kunamanje, njengabahlengikazi batusa. Yebo, i-adwes yabantu abanempilo ezinjalo ukulinganiselwa ayikho nhlobo.
