Ukunganyamezelani kweLactose

I-Lactose luhlobo lweswekile olufumaneka kubisi nakwezinye iimveliso zobisi. I-enzyme ebizwa ngokuba yi-lactase iyafuneka emzimbeni ukwetyisa i-lactose.

Ukunganyamezelani kweLactose kuyenzeka xa ithumbu elincinci lingenzi ngokwaneleyo kule enzyme.

Imizimba yabantwana yenza i-enzyme ye-lactase ukuze bakwazi ukucola ubisi, kubandakanya ubisi lwebele.

• Iintsana ezizalwe kwangoko (ngaphambi kwexesha) ngamanye amaxesha zinokunganyamezelani kwe-lactose.
• Abantwana abazalwe ngexesha elipheleleyo bahlala bengabonisi zimpawu zengxaki bengakabi neminyaka emi-3 ubudala.

Ukunganyamezelani kweLactose kuqheleke kakhulu kubantu abadala. Ayifane ibe yingozi. Malunga nezigidi ezingama-30 zabantu abadala baseMelika banesidanga esithile sokunganyamezelani kwe-lactose eneminyaka engama-20.

• Kubantu abamhlophe, ukunganyamezelani kwe-lactose kuhlala kukhula kubantwana abadala kuneminyaka eyi-5. Eli lixesha apho imizimba yethu inokuyeka ukwenza i-lactase.
• Kubantu base-Afrika baseMelika, ingxaki inokubakho kwasekuqaleni kweminyaka emi-2.
• Le meko ixhaphake kakhulu phakathi kwabantu abadala abaneAsia, iAfrika, okanye ilifa lamaMelika aseMelika.
• Akuqhelekanga kubantu abasempuma okanye entshona yeYurophu, kodwa kusenokwenzeka.

Isifo esichaphazela okanye esenzakalisa amathumbu akho amancinci sinokubangela ukuba kwenziwe i-enzyme encinci ye-lactase. Unyango lwezi zifo lunokuphucula iimpawu zokunganyamezelani kwe-lactose. Oku kunokubandakanya:

• Utyando lwamathumbu amancinci
• Usulelo kumathumbu amancinci (oku kubonakala rhoqo kubantwana)
• Izifo ezonakalisa amathumbu amancinci, njenge-celiac sprue okanye isifo seCrohn
• Nasiphi na isifo esibangela urhudo

Iintsana zinokuzalwa zinesiphene semfuza kwaye azikwazi ukwenza nayiphi na i-enzyme ye-lactase.

Iimpawu zihlala zivela kwimizuzu engama-30 ukuya kwiiyure ezimbini emva kokuba neemveliso zobisi. Iimpawu zinokuba zibi ngakumbi xa usitya izixa ezikhulu.

Iimpawu zibandakanya:

• Ukudumba kwesisu
• Iintlanzi zesisu
• Urhudo
• Irhasi (ukuqunjelwa)
• Isicaphucaphu

Ezinye iingxaki zamathumbu, ezinje ngesifo sengqondo esiswini, zinokubangela iimpawu ezifanayo nokunganyamezelani kwe-lactose.

Uvavanyo lokunceda ukufumanisa ukunganyamezelani kwe-lactose kubandakanya:

• Uvavanyo lokuphefumla lwe-Lactose-hydrogen
• Uvavanyo lokunyamezelana neLactose
• Isitro pH

Enye indlela inokuba ngumceli mngeni kwisigulana nge-25 ukuya kwi-50 yeegramu zelactose emanzini. Iimpawu ziyavavanywa kusetyenziswa iphepha lemibuzo.

Uvavanyo lwe-1 ukuya kwe-2 lweveki yokutya okungenayo i-lactose ngokupheleleyo ngamanye amaxesha kuyazama.

Ukunciphisa ukutya kwakho iimveliso zobisi ezinelactose ekudleni kwakho kuhlala kunciphisa iimpawu. Jonga kwakhona iilebheli zokutya zemithombo efihliweyo yelactose kwiimveliso ezingezizo ezobisi (kubandakanya ezinye iibhiya) kwaye uziphephe.

Uninzi lwabantu abanqanaba eliphantsi le-lactase banokusela ikomityi enye yobisi ngexesha elinye (ii-ounces ezi-2 ukuya kwezi-4 okanye i-60 ukuya kwi-120 milliliters) ngaphandle kokuba neempawu. Ukuhanjiswa okukhulu (ngaphezulu kwee-ounces eziyi-8 okanye i-240 mL) kunokubangela iingxaki kubantu abanesiphene.

Iimveliso zobisi ezinokuba lula ukwetyisa zibandakanya:

• Ibhotolo kunye neentshizi (oku kutya kunelactose encinci kunobisi)
• Iimveliso zobisi ezivuthiweyo, njengeyogathi
• Ubisi lweebhokhwe
• Iitshizi ezinzima ezindala
• Ubisi lweLactose kunye neemveliso zobisi
• Ubisi lweenkomo oluphathwe nge-Lactase kubantwana abadala nakubantu abadala
• Iifomula zeSoy zabantwana abangaphantsi kweminyaka emi-2
• I-Soy okanye ubisi lwerayisi kubantwana abancinci

Unokongeza ii-enzymes ze-lactase kubisi oluqhelekileyo. Unokuthatha ezi enzymes njengeephilisi okanye iipilisi ezihlafunwayo. Kukwakho neemveliso zobisi oluninzi olungena-lactose.

Ukungabi nabisi kunye nezinye iimveliso zobisi ekudleni kwakho kunokukhokelela ekunqongophaleni kwe-calcium, i-vitamin D, i-riboflavin kunye neprotheni. Udinga i-1,000 ukuya kwi-1,500 mg ye-calcium yonke imihla ngokuxhomekeke kubudala bakho kunye nesini. Ezinye izinto onokuzenza ukuze ufumane ikhalsiyam ngakumbi ekutyeni kwakho zezi:

• Thatha izongezo zekhalsiyam enoVitamin D. Thetha nomboneleli wakho wezempilo ukuba ukhethe eziphi.
• Yitya ukutya okune-calcium engaphezulu (njengemifuno enamagqabi, iimbatyisi, isardadi, isalmon enkonkxiweyo, i-shrimp kunye ne-broccoli).
• Sela ijusi yeorenji kunye necalcium eyongeziweyo

Iimpawu zihlala zihamba xa ususa ubisi, ezinye iimveliso zobisi, kunye neminye imithombo ye-lactose ekutyeni kwakho. Ngaphandle kotshintsho kwindlela otya ngayo, iintsana okanye abantwana banokuba neengxaki zokukhula.

Ukuba ukunganyamezelani kwe-lactose kubangelwe sisifo sohudo sethutyana, amanqanaba e-enzyme ye-lactase aya kubuyela esiqhelweni kwiiveki nje ezimbalwa.

Fowunela umnikezeli wakho ukuba:

• Unomntwana ongaphantsi kweminyaka emi-2 okanye emithathu ubudala oneempawu zokunganyamezelani kwe-lactose.
• Umntwana wakho ukhula kancinci okanye akafumani bunzima.
• Wena okanye umntwana wakho uneempawu zokunganyamezelani ne-lactose kwaye ufuna ulwazi malunga nokutya endaweni yoko.
• Iimpawu zakho ziya zisiba mbi okanye aziphucuki kunyango.
• Uba neempawu ezintsha.

Akukho ndlela yaziwayo yokuthintela ukunganyamezelani kwe-lactose. Unokuthintela iimpawu ngokuphepha ukutya kunye ne-lactose.
