Ukubaluleka kweIvithamin D: Ikhonkco phakathi kweLanga kunye neMpilo

Kuluntu lwanamhlanje, njengoko iindlela zokuphila zabantu ziguquka, ukunqongophala kwevithamin D kuye kwaba yingxaki eqhelekileyo. I-Vitamin D ayiyimfuneko kuphela kwimpilo yamathambo, kodwa idlala indima ebalulekileyo kwi-immune system, impilo ye-cardiovascular, kunye nempilo yengqondo. Eli nqaku liza kuphonononga ukubaluleka kwevithamin D kunye nendlela yokufumana ivithamin D eyaneleyo ngokutya kunye nokukhanya kwelanga.

Ulwazi olusisiseko lweivithamin D

Ivithamin Dyivithamini enyibilikayo ngamanqatha eza kwiintlobo ezimbini eziphambili: i-vitamin D2 (ergocalciferol) kunye ne-vitamin D3 (cholecalciferol). I-Vitamin D3 yenziwe ngesikhumba ekuphenduleni ukukhanya kwelanga, ngelixa i-vitamin D2 ngokuyinhloko ivela kwizityalo ezithile kunye nemvubelo. Umsebenzi ophambili wevithamin D kukunceda umzimba ufunxe icalcium kunye nephosphorus, eziyimfuneko ekugcineni amathambo namazinyo esempilweni.

Impembelelo yevithamin D kwimpilo yamathambo

Ivithamin D idlala indima ebalulekileyo kwimpilo yamathambo. Ikhuthaza ukufunxwa kwe-calcium emathunjini kwaye inceda ukugcina amanqanaba e-calcium egazini, ngaloo ndlela ixhasa inkqubo ye-mineralization yamathambo. Ukunqongophala kweVithamini D kunokukhokelela kwi-osteoporosis, ukwanda komngcipheko wokuqhekeka, kunye ne-rickets ebantwaneni. Ngoko ke, ukuqinisekisa ukuba i-vitamin D eyaneleyo iyisitshixo sokuthintela isifo samathambo.

I-Vitamin D kunye ne-Immune System

Uphononongo lwakutsha nje lubonise ukuba ivithamin D nayo idlala indima ebalulekileyo kumajoni omzimba. Iyakwazi ukulawula ukusebenza kweeseli zomzimba kunye nokwandisa ukuxhathisa komzimba kusulelo. Ukunqongophala kwe-Vitamin D kuhambelana neentlobo zezifo ezizimele (ezifana ne-multiple sclerosis, i-rheumatoid arthritis, njl.) kunye nomngcipheko wokosuleleka. Ngoko ke, ukugcina amanqanaba e-vitamin D afanelekileyo kunokunceda ukwandisa ukhuseleko kunye nokunciphisa umngcipheko wosulelo kunye nesifo.

I-Vitamin D kunye nempilo yengqondo

Ukunqongophala kweVithamin D kukwanxulumene ngokusondeleyo neengxaki zempilo yengqondo. Uphononongo lufumanise ukuba amanqanaba asezantsi evithamin D anxulunyaniswa nokwanda kwezehlo zeengxaki zempilo yengqondo ezifana nokudakumba kunye nokuxhalaba. I-Vitamin D inokuchaphazela isimo sengqondo ngokuchaphazela ukuhlanganiswa kwee-neurotransmitters (ezifana ne-serotonin) kwingqondo. Ke ngoko, ukongezwa kwe-vitamin D kunokunceda ukuphucula impilo yengqondo kunye nokuphucula umgangatho wobomi.

Indlela yokufumana ivithamin D eyaneleyo

1. Ukukhanya kwelanga: Ukukhanya kwelanga yeyona ndlela yendalo nesebenzayo yokufumana ivithamin D. Ulusu luyakwazi ukudibanisa ivithamin D xa lubekwe elangeni. Kucetyiswa ukuba ubekwe kwindawo yelanga imizuzu eyi-15 ukuya kwengama-30 ngosuku, ngakumbi ngeeyure zokukhanya kwelanga okunamandla (10 am ukuya ku-3 pm). Nangona kunjalo, izinto ezinjengombala wolusu, indawo yendawo kunye nexesha lonyaka zinokuchaphazela ukwakheka kwe-vitamin D, ngoko ke kwezinye iimeko, ukongezwa okongeziweyo kunokufuneka.

2. Ukutya: Nangona ukukhanya kwelanga kungumthombo oyintloko, unokufumana i-vitamin D ngokutya. Ukutya okutyebileyo kwivithamin D kubandakanya:
-Intlanzi (efana nesalmon, isardadi, cod)
- Ivokhado, iqanda lomthubi
- Ukutya okongeziweyo (njengobisi oluqinisiweyo, ijusi yeorenji, kunye neesiriyeli)

3. Izongezo: Kwabo bangakwaziyo ukufumana okwaneleyoivithamin Dngokukhanya kwelanga kunye nokutya, izongezo ziyindlela esebenzayo.Vitamin D3izongezo zithathwa njengeyona ndlela isebenzayo. Ngaphambi kokuqala ukuxhaswa, kucetyiswa ukuba udibane nodokotela ukuze unqume umthamo ofanelekileyo.

Ukhuseleko kunye nezilumkiso zeivithamin D

Nangona i-vitamin D ibalulekile kwimpilo, ukutya kakhulu kunokubangela iingxaki zempilo. Ubuthi bevithamin D bubangelwa kakhulu yimpembelelo yayo kwimetabolism ye-calcium, enokukhokelela kwiingxaki ezinjenge-hypercalcemia. Ngoko ke, kubaluleke kakhulu ukulandela ukuthathwa okucetyiswayo. Ukuthathwa kwemihla ngemihla okucetyiswayo kubantu abadala ngamayunithi angama-600-800 amazwe ngamazwe (IU), anokulungiswa ngokwemeko yempilo yomntu kunye neengcebiso zikagqirha.

Ivithamin Didlala indima ebalulekileyo ekugcineni impilo entle. Nokuba yimpilo yamathambo, amajoni omzimba okanye impilo yengqondo, ivithamin D idlala indima ebalulekileyo. Ukuqinisekisa amanqanaba aneleyo e-vitamin D emzimbeni ngokusebenzisa ukukhanya kwelanga okufanelekileyo, ukutya okunokulinganisela kunye nezongezelelo eziyimfuneko kuya kunceda ukuphucula impilo yonke. Nika ingqalelo ukubaluleka kwevithamin D kwaye masiphile ubomi obunempilo elangeni.

I-Vitamin D nayo i-hormone ye-steroid. Ibandakanya ikakhulu i-VD2 kunye ne-VD3, enesakhiwo esifana kakhulu. I-Vitamin D3 kunye ne-D2 iqhutyelwa ngokujikeleza kwegazi kwisibindi kwaye iguqulelwe kwi-25-hydroxy Vitamin D (kuquka i-25- dihydroxyl i-Vitamin D3 kunye ne-D2) ngempembelelo ye-Vitamin D-25-hydroxylase. I-25-hydroxy I-Vitamin D iguqulwa kakhulu kwi-physiologically active 1, i-25- dihydroxyl i-Vitamin D kwi-intso phantsi kwe-catalysis ye-25OH-1α hydroxylase. 25-(OH)VDIkhona kumzimba womntu ekugxininiseni okuphezulu kwaye ngokuzinzileyo, kwaye inokubonisa inani elipheleleyo leVithamin D efakwe ekutyeni kwaye idityaniswe ngumzimba kunye nekhono lokuguqula iVitamin D. Ke ngoko,25-(OH)VDithathwa njengesona salathisi sokuvavanya imeko yesondlo seVithamin D.
