Thiamin

I-Thiamin yenye yeevithamini ze-B. Iivithamini ze-B liqela leevithamini ezinyibilikayo emanzini eziyinxalenye yeendlela ezininzi zokuphendula ngamachiza emzimbeni.

I-Thiamin (i-vitamin B1) inceda iiseli zomzimba ukutshintsha ii-carbohydrate zibe ngamandla. Indima ephambili yee-carbohydrate kukubonelela ngamandla emzimbeni, ngakumbi kwingqondo nakwinkqubo yemithambo-luvo.

U-Thiamin naye udlala indima kuthintelo lwezihlunu kunye nokuqhutywa kweempawu zemithambo-luvo.

I-Thiamin ibalulekile kwimetabolism ye-pyruvate.

I-Thiamin ifumaneka:

• Ityetyisiwe, yaqiniswa, kunye nemveliso yeenkozo ezinje ngesonka, iisiriyeli, irayisi, ipasta kunye nomgubo
• Imbotyi yengqolowa
• Inyama yenkomo kunye nengulube
• Trout kunye ne-tuna ye-bluefin
• Iqanda
• Iimbotyi kunye nee-ertyisi
• Amandongomane nembewu

Iimveliso zobisi, iziqhamo, kunye nemifuno aziphezulu kakhulu kwi-thiamin ngexabiso elincinci. Kodwa xa usitya izixa ezikhulu zezi, ziba ngumthombo obalulekileyo we-thiamin.

Ukunqongophala kwe-thiamin kunokubangela ubuthathaka, ukudinwa, isifo sengqondo kunye nomonakalo wemithambo-luvo.

Ukunqongophala kwetyhefu eUnited States kuhlala kubonakala kubantu abasebenzisa gwenxa utywala (alcoholism). Utywala obuninzi benza ukuba kube nzima emzimbeni ukufunxa ityamin ekutyeni.

Ngaphandle kokuba abo banxila bafumane izixa ezingaphezulu kuneqhelekileyo zesiqhelo se-thiamin ukwenza umahluko, umzimba awuyi kufumana ngokwaneleyo loo nto. Oku kunokukhokelela kwisifo esibizwa ngokuba yi-beriberi.

Ukusilela kakhulu kwe-thiamin, ukwenzeka kwengqondo kunokwenzeka. Olunye uhlobo lubizwa ngokuba yi-Korsakoff syndrome. Esinye sisifo seWernicke. Nokuba zombini okanye zombini ezi meko zinokwenzeka kumntu ofanayo.

Akukho tyhefu yaziwayo inxulunyaniswe ne-thiamin.

Isibonelelo seDiary esicetyiswayo (i-RDA) sevithamini sibonisa ukuba uninzi lwevithamini uninzi lwabantu kufuneka lufumane usuku ngalunye. I-RDA yeevithamini inokusetyenziselwa iinjongo zomntu ngamnye.

Ingakanani ivithamini nganye oyifunayo kuxhomekeke kubudala bakho kunye nesini. Ezinye izinto, ezinjengokukhulelwa kunye nokugula, nazo zibalulekile. Abantu abadala kunye nabasetyhini abakhulelweyo okanye abancancisayo badinga amanqanaba aphezulu e-thiamin kunabantwana abancinci.

Ukungeniswa kwereferensi yokutya kwi-thiamin:

Iintsana

• Iinyanga ezi-0 ukuya kwezi-6: 0.2 * milligrams ngosuku (mg / ngosuku)
• Iinyanga ezi-7 ukuya kwezi-12: 0.3 * mg / ngosuku

Ukutya okwaneleyo (AI)

Abantwana

• 1 ukuya kwiminyaka emi-3: 0.5 mg / ngosuku
• I-4 ukuya kwi-8 iminyaka: 0.6 mg / ngosuku
• Iminyaka eli-9 ukuya kweli-13: 0.9 mg / ngosuku

Ulutsha kunye nabantu abadala

• Amadoda aneminyaka eli-14 nangaphezulu: 1.2 mg / ngosuku
• Abasetyhini abaneminyaka eli-14 ukuya kweli-18 ubudala: 1.0 mg / ngosuku
• Abasetyhini abaneminyaka eli-19 nangaphezulu: 1.1 mg / ngosuku (1.4 mg efunekayo ngexesha lokukhulelwa kunye nokuncancisa)

Eyona ndlela yokufumana imfuno yemihla ngemihla yeevithamini eziyimfuneko kukutya ukutya okunesondlo okuqulethe iintlobo ezahlukeneyo zokutya.
