Ngokusho kwe-National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), abantu abayizigidi ezingu-30-50 e-US kuphela abakwazi ukubekezelela i-lactose (i-6 kubantu abangu-XNUMX). Ingabe lesi simo ngempela kufanele sibhekwe njengokuchezuka kokujwayelekile?
Kuyini ukungabekezelelani kwe-lactose?
Eyaziwa nangokuthi "ushukela wobisi", i-lactose iyi-carbohydrate eyinhloko emikhiqizweni yobisi. Ngesikhathi sokugaya, i-lactose idilizwa ibe ushukela kanye ne-galactose ukuze imunce umzimba. Lesi sinyathelo senzeka emathunjini amancane ngosizo lwe-enzyme ebizwa ngokuthi i-lactase. Abantu abaningi baye, noma bathuthuke ngokuhamba kwesikhathi, ukushoda kwe-lactase okuvimbela umzimba ekugayeni kahle yonke noma ingxenye ye-lactose abayidlayo. I-lactose engagayeki ibe isingena emathunjini amakhulu, lapho yonke “i-cheese-boron” iqala khona. Ukushoda kwe-Lactase kanye nezimpawu ezibangelwa yi-gastrointestinal yilokho okuvame ukubizwa ngokuthi ukubekezelelana kwe-lactose.
Ubani othambekele kulesi simo?
Amanani aphezulu kubantu abadala futhi ahluka kakhulu ngobuzwe. Ngokocwaningo lwe-NIDDK lwango-1994, ukwanda kwalesi sifo e-United States kuveza lesi sithombe esilandelayo:
Emhlabeni wonke, cishe amaphesenti angama-70 abantu abangakwazi ukubekezelela i-lactose ngandlela thile futhi basengozini yokungezwani ne-lactose. Akukho ukuncika kusibonisi sobulili okutholakele. Kodwa-ke, kuyathakazelisa ukuthi abanye besifazane bangakwazi ukubuyisela amandla okugaya i-lactose ngesikhathi sokukhulelwa.
Ziyini izimpawu?
Izimpawu ziyahlukahluka kumuntu nomuntu: ezincane, ezimaphakathi, ezinzima. Eziyisisekelo kakhulu zihlanganisa: ubuhlungu besisu, amajaqamba besisu, ukuqunjelwa, flatulence, isifo sohudo, isicanucanu. Lezi zimo zivame ukuvela emizuzwini engama-30 - amahora ama-2 ngemuva kokudla ukudla kobisi.
Ithuthuka kanjani?
Kwabaningi, ukungezwani ne-lactose kukhula ngokuzenzakalelayo lapho umuntu esekhulile, kanti kwabanye kutholaka ngenxa yokugula okunzima. Isibalo esincane kuphela sabantu esintula i-lactase kusukela ekuzalweni.
I-lactose ibangelwa ukwehla kancane kancane kwemvelo komsebenzi we-lactase ngemva kokuyeka ukuncelisa. Ngokuvamile umuntu ugcina kuphela i-10-30% yezinga lokuqala lomsebenzi we-enzyme. i-lactose ingenzeka ngokumelene nesizinda sokugula okunzima. Lokhu kuvamile kunoma ibuphi ubudala futhi kungase kunyamalale ngemva kokululama ngokuphelele. Izimbangela eziningana ezingase zibe khona zokungabekezelelani kwesibili i-irritable bowel syndrome, i-acute gastroenteritis, isifo se-celiac, umdlavuza, kanye nokwelashwa ngamakhemikhali.
Mhlawumbe ukungagayeki kahle?
Yiqiniso, iqiniso lokungabekezelelani kwe-lactose alibuzwa omunye umuntu ngaphandle ... imboni yobisi. Eqinisweni, i-National Dairy Board iphakamisa ukuthi abantu abanakho nhlobo ukubekezelela i-lactose, kodwa izimpawu zokungagayeki kahle okubangelwa ukusetshenziswa kwe-lactose. Phela, kuyini ukungagayeki? Ukuphazamiseka kokugaya ukudla okubangela izimpawu zesisu kanye nempilo ebuthaka. Njengoba kushiwo ngenhla, abanye bagcina amanye ama-enzyme e-lactose futhi ngenxa yalokho bayakwazi ukugaya imikhiqizo yobisi ngaphandle kwezimpawu ezibonakalayo.
Okufanele ngikwenze?
Isayensi ayikacabangi ukuthi ingakhuphula kanjani ikhono lomzimba lokukhiqiza i-lactase. "Ukwelashwa" kwalesi simo okuxoxwa ngakho kulula futhi, ngesikhathi esifanayo, kunzima kwabaningi: ukwenqatshwa kancane kancane kwemikhiqizo yobisi. Kunamaqhinga amaningi ngisho nezinhlelo ezikusiza ukuthi ushintshele ekudleni okungenalo ubisi. Into eyinhloko okufanele uyiqonde ukuthi izimpawu zalokho okubizwa ngokuthi "ukungabekezelelani kwe-lactose" yisimo esingenabuhlungu esibangelwa kuphela ukudla okungezona izinhlobo zezinhlobo.
