Ukudla izithelo nemifino eminingi kuvame ukutuswa ukulahlekelwa isisindo ngoba kukwenza uzizwe ugcwele, kodwa lokhu kungaba ukuphela kokufa, ngokusho kocwaningo olusha oluvela eNyuvesi yase-Alabama e-Birmingham, eshicilelwe ku-American Journal of Clinical Nutrition.
Ngokwe-USDA's My Plate Initiative, ukunikezwa okunconyiwe kwansuku zonke kwabantu abadala yinkomishi yezithelo engu-1,5-2 kanye nezinkomishi ezingu-2-3 zemifino. Katherine Kaiser, PhD, AUB Public Health Faculty Instructor, kanye nethimba labacwaningi kuhlanganise no-Andrew W. Brown, PhD, Michelle M. Moen Brown, PhD, James M. Shikani, Dr. Ph. kanye noDavid B. Ellison, PhD, kanye Abacwaningi baseNyuvesi yasePurdue benze ukubuyekezwa okuhlelekile kanye nokuhlaziywa kwemeta kwedatha evela kubahlanganyeli abangaphezu kwe-1200 ezivivinyweni eziyisikhombisa ezilawulwa ngokungahleliwe ezigxile ekwandiseni inani lezithelo nemifino ekudleni kanye nomphumela wokulahlekelwa isisindo. Imiphumela yabonisa ukuthi ukwandisa ukudla kwezithelo nemifino kuphela akuzange kunciphise isisindo.
"Sekukonke, zonke izifundo esizibuyekezile zibonisa cishe akukho mphumela wokulahlekelwa isisindo," kusho uKaiser. “Ngakho-ke angicabangi ukuthi udinga ukudla kakhulu ukuze wehlise isisindo. Uma wengeza izithelo nemifino eyengeziwe ekudleni okuvamile, cishe ngeke ulahlekelwe isisindo. Yize abantu abaningi bekholelwa ukuthi izithelo zingakwenza ukhuluphale, uKaiser uthi lokhu akubonwanga ngomthamo.
“Kuvele ukuthi uma udla izithelo nemifino kakhulu, awukhululi, okuhle ngoba kukuvumela ukuthi uthole amavithamini amaningi nefiber,” usho kanje. Nakuba evuma izinzuzo zezempilo zezithelo nemifino, izinzuzo zabo zokulahlekelwa isisindo zisabuzwa.
"Ezimweni ezijwayelekile zokudla okunempilo, ukunciphisa amandla kusiza ukunciphisa isisindo, futhi ukunciphisa amandla, udinga ukunciphisa inani lamakholori asetshenzisiwe," kusho uKaiser. - Abantu bacabanga ukuthi imifino nezithelo ezinothe nge-fiber zizothatha indawo yokudla okunempilo encane futhi ziqale indlela yokunciphisa isisindo; ucwaningo lwethu, nokho, lubonisa ukuthi lokhu akwenzeki kubantu abavele baqale ukudla izithelo nemifino eyengeziwe.”
"Ezempilo yomphakathi, sifuna ukunikeza abantu imiyalezo eyakhayo nekhuthazayo, futhi ukutshela abantu ukuthi badle izithelo nemifino okuningi kuhle kakhulu kunokuthi "dla kancane." Ngeshwa, kubonakala sengathi uma abantu beqala ukudla izithelo nemifino eminingi, kodwa benganciphisi inani eliphelele lokudla, isisindo asishintshi, "kusho umcwaningi omkhulu uDavid W. Ellison, PhD, umqondisi wesayensi yemvelo e-UAB Institute of Impilo Yomphakathi.
Ngenxa yokuthi lesi sincomo sivame kakhulu, uKaiser uthemba ukuthi okutholakele kuzokwenza umehluko.
Kunezifundo eziningi lapho abantu bechitha imali eningi bezama ukuthola ukuthi bangakwandisa kanjani ukudla kwabo izithelo nemifino, futhi kunezinzuzo eziningi kulokhu; kodwa ukuncipha akuyona enye yazo,” kusho uKaiser. "Ngicabanga ukuthi ukusebenzela ukuguqula indlela yokuphila ebanzi kungaba ukusetshenziswa okungcono kakhulu kwemali nesikhathi."
U-Kaiser uthi ucwaningo olwengeziwe luyadingeka ukuze kuqondwe ukuthi ukudla okuhlukene kungase kuhlanganyele kanjani ekunciphiseni isisindo.
“Kumele senze ucwaningo lwemishini ukuze sikuqonde lokhu, bese sikwazi ukwazisa umphakathi ngokumele ukwenze uma kunenkinga yokuncipha. Ulwazi olwenziwe lula alusebenzi kangako,” kusho yena.
