Iimpawu zokunqongophala kwevithamini A

Umxholo

• Xa umngcipheko wokukhubazeka mkhulu
• Imali ecetyiswayo ngosuku

Iimpawu zokuqala zokunqongophala kukavithamini A kubunzima ekuziqhelaniseni nombono wasebusuku, ulusu olomileyo, iinwele ezomileyo, iinzipho ezaphukileyo kunye nokwehla kwamajoni omzimba, ngokubonakala rhoqo komkhuhlane kunye nosulelo.

Xa ujongene nokusilela, iimpawu zokungabikho kwevithamini A zibandakanya:

Ukunqongophala kukaVitamin A kuxhaphake kakhulu kubantu abangondlekanga, kubantu abadala nakwimeko yezifo ezinganyangekiyo, ezinjengesifo sokudumba.

Xa umngcipheko wokukhubazeka mkhulu

Njengokuba ivithamin A yivithamini enyibilika ngamanqatha, izifo ezichaphazela ukufunxeka kwamathumbu emathunjini zikwaphelisa ukunciphisa ukufunxeka kukavithamini A. Ke, iingxaki ezinje ngecystic fibrosis, ukungabikho kwepancreatic, isifo sokudumba, isifo seCholestasis okanye iimeko zebariatric ukugqithisa utyando emathunjini amancinci, ukwandisa umngcipheko wokubangela ukunqongophala kukavithamini A.

Ukongeza, ukusela kakhulu utywala kunciphisa ukuguqulwa kwe-retinol ibe yi-retinoic acid, eyindlela esebenzayo yevithamini A kwaye eyenza imisebenzi yayo emzimbeni. Ke, ukunxila kunokubangela ukuvela kweempawu zokunqongophala kwale vithamini.

Imali ecetyiswayo ngosuku

Inani levithamini A elicetyiswayo ngosuku liyahluka ngokobudala, njengoko kubonisiwe ngezantsi:

• Abantwana abangaphantsi kweenyanga ezi-6: 400 mcg
• Abantwana ukusuka kwiinyanga ezisi-7 ukuya kwezi-12: 500 mcg
• Abantwana ukusuka kwi-1 ukuya kwi-3 yeminyaka ubudala: 300 mcg
• Abantwana abaneminyaka emi-4 ukuya kwe-8 ubudala:400 mcg
• Abantwana abaneminyaka emi-3 ukuya kweli-13 ubudala: 600 mcg
• Amadoda ngaphezulu kweminyaka eli-13 ubudala:I-1000 mcg
• Abafazi ngaphezulu kweminyaka eyi-10: 800 mcg

Ngokubanzi, ukutya okusempilweni nokwahluka-hlukeneyo kwanele ukuhlangabezana neengcebiso zemihla ngemihla zovithamini A, kubalulekile ukuthatha kuphela izongezo zale vithamini ngokhokelo lukagqirha okanye lonyango.
