Buyini ubudlelwano bokuntula uvithamini D nokucindezeleka?

Ucwaningo olusafufusa lukhomba ukuxhumana phakathi kukavithamini D nokucindezeleka Sekuyisikhathi eside kwaziwa ukuthi uvithamini D ubalulekile uma kuziwa ekugcineni amathambo aqinile nokuqinisa amasosha omzimba, kodwa ucwaningo olusha lubheke ukuthi kukhona yini ukuxhumana phakathi kukavithamini D nokucindezeleka. . Imiphumela yocwaningo ixubile.Kunobufakazi obukhulayo obuphakamisa ubudlelwano obungaba khona phakathi kwamazinga aphansi kavithamini D ojikelezayo kanye nokudangala, ngokusho kwe-Live Science.

Ukucindezeleka kungathinta izici zempilo yansuku zonke, kusukela ekuxhumaneni nomphakathi kuya ekulaleni. Nakuba kunezindlela ezisekelwe kahle zokwelapha ukucindezeleka, indima engaba khona kavithamini D idonsela ukunaka. Ekubuyekezeni ucwaningo lwakamuva, umbiko oshicilelwe yi-Live Science unikeza idatha egcwele ngendima kavithamini D, izimpawu zokuntuleka nokucindezeleka, kanye nezinyathelo ezingokoqobo zokuthola uvithamini D owanele, okuhlanganisa nezithasiselo zikavithamini D ezihamba phambili. Ngesikhathi esifanayo, lo mbiko uphawula isidingo sokubonisana nochwepheshe uma umuntu ehlushwa izinkinga ezingokwengqondo futhi ngaphambi kokwenza noma yiziphi izinguquko ezibalulekile ekudleni.

Ivithamini D

Okokuqala, uvithamini D usebenza emzimbeni lapho imisebe ye-ultraviolet evela elangeni ishaya esikhumbeni, eshukumisa ukukhiqizwa kukavithamini D. Yingakho ibizwa ngokuthi “ivithamini yokukhanya kwelanga.” Ngaphambi kokuba umzimba uwusebenzise, ​​kufanele kuqaliswe uvithamini D. Isibindi siyawuguqula ube i-calcidiol, yona ibe i-calcitriol ezinso.

I-Vitamin D ilawula inani le-calcium egazini, "inikeza amandla emathanjeni, amazinyo, nezicubu ngokumunca i-calcium ne-phosphorus emzimbeni," kusho uchwepheshe wezokudla obhalisiwe nomkhulumeli we-Academy of Nutrition and Dietetics uSue Ellen Anderson-Heinz. Iphinde ibe neqhaza esimisweni sokuzivikela komzimba, ucwaningo lubonisa ukuthi amazinga aphansi kavithamini D ahlotshaniswa nokwanda kwezifo kanye nezifo ezizimele.

Ukuxhumana phakathi kwevithamini D nokucindezeleka

Imiphumela yocwaningo ivuse isithakazelo ekuhlobaneni phakathi kukavithamini D nokucindezeleka. UDkt. Anderson-Heinz uyachaza: “Ucwaningo lwamuva lubonisa ukuthi amazinga aphansi kavithamini D avame ukubonakala kulabo okutholakala ukuthi banokucindezeleka okungokomzimba, [okusikisela] ubuhlobo obuphambene,” kuchaza uDkt.

Okunye ukubuyekezwa kwesayensi, okushicilelwe kuyiBritish Journal of Psychiatry, kuhlole idatha evela kubahlanganyeli abangaphezu kuka-30000 futhi kwathola ukuthi abantu abanokucindezeleka bavame ukuba namazinga aphansi kavithamini D. Ubunjalo bobudlelwane phakathi kwevithamini D nokucindezeleka abuqondi ngokugcwele, kodwa kunezincazelo ezimbalwa.ezingenzeka, nakuba zingekho ezifakazelwe.

Enye inkolelo-mbono engenzeka ukuthi ukuntuleka kwevithamini D kubangela ukucindezeleka. Uma kunjalo, izithasiselo zingase zisize ekudambiseni izimpawu. Kodwa izifundo zibonisa imiphumela exubile. Okunye ukubuyekezwa kwesayensi, okushicilelwe kumagazini i-CNS Drugs, kwathola ukuthi ukwengezwa kwe-vitamin D kukhulula izimpawu kubantu abanokucindezeleka, futhi umphumela wawubonakala kakhulu kubantu abanenkinga enkulu yokucindezeleka. Kodwa imiphumela yolunye ucwaningo, eyanyatheliswa ku-BMC Research Notes, ibonise ukuthi uvithamini D awenzi mehluko omkhulu uma kuqhathaniswa ne-placebo, kuyilapho okunye ukubuyekezwa kwesayensi kusikisela ukuthi ubuhlobo bungase busebenze ngendlela ehlukile, njengoba abantu abanokucindezeleka kungenzeka kakhulu ngenxa yokuntuleka kwevithamini D ngenxa yokuthi maningi amathuba okuba bahoxe ezenzweni zokuzijabulisa futhi bachithe isikhathi esincane bengaphandle.

Kuneminye imibono mayelana nokuxhumana phakathi kukavithamini D nokucindezeleka. Ukubuyekezwa okukodwa, okushicilelwe kuyi-Indian Journal of Psychiatry, kuphawula ukuthi kunama-receptors amaningi kavithamini D ezifundeni zobuchopho ezidlala indima ekujuleni kwemizwa, okuhlanganisa i-prefrontal cortex kanye ne-cingulate. I-Vitamin D iphinde ilawule i-hypothalamic-pituitary-adrenal axis, ithonya isimo sengqondo.

Ukubuyekezwa okufanayo kukhomba enye inkolelo-mbono engase ihlobane namasosha omzimba. Ukucindezeleka kuhlotshaniswa namazinga aphezulu okuvuvukala okungapheli, okwenzeka lapho impendulo yokuzivikela komzimba iqala ngokungadingekile. Phakathi naleso sikhathi, i-vitamin D iyaziwa ngokusekela amasosha omzimba futhi ibe nemiphumela elwa nokuvuvukala.

Izimpawu zokushoda kwe-vitamin D nokucindezeleka

Ucwaningo lwesayensi nokubuyekezwa kukhombisa ukuthi kukhona ukunqwabelana phakathi kwezimpawu zokushoda kwevithamini D ngale ndlela elandelayo:

I-US National Institute of Mental Health ifingqa izimpawu zokucindezeleka ngale ndlela elandelayo:

• Isimo sengqondo sokudabuka noma ukukhathazeka okuqhubekayo
• Imizwa yokuphelelwa ithemba
• Ukuntuleka kwamandla nokukhathala
• Izinhlungu noma izinhlungu ngaphandle kwesizathu esibonakalayo futhi ezingaqediwe ngokwelashwa
• Ukulahlekelwa intshisekelo noma ukujabulela izinto zokuzilibazisa kanye nemisebenzi
• Imicabango ngokufa noma ukuzibulala

NgokukaDkt. Anderson-Hines, MD, othweswe iziqu eNyuvesi yaseFlorida oneziqu ze-masters e-Andrews University, izimpawu zokuqala zokuntuleka kukavithamini D yilezi:

• Ukukhathala
• ukufinyela
Ubuthakathaka bemisipha

Umbiko ovela eCleveland Clinic uphawula ukuthi ukushintsha kwemizwelo, okuhlanganisa nezimpawu zokucindezeleka, kungase kube uphawu lokuntuleka kwevithamini D.
Ngokuhamba kwesikhathi, umthelela emathanjeni nasemazinyweni ungaholela ekubeni ama-rickets ezinganeni nasemathanjeni athambile noma i-osteomalacia kubantu abadala, ngakho bheka uchwepheshe wezokwelapha uma umuntu ekhathazekile nganoma iyiphi yalezi zimpawu.

Imithombo ye-vitamin D

I-US National Institutes of Health iphawula ukuthi ukudla okunovithamini D kuyashoda.” “Kuya ngokuthi udla kangakanani, ukudla okunjengejusi yamawolintshi, ubisi lwezitshalo oluqiniswe ngovithamini D, amakhowe aphethwe yi-UV, amasardine nezikhupha zamaqanda. ingase ikunikeze uvithamini D owanele,” kusho uDkt. Anderson-Heinz. Ukuchayeka elangeni njalo kubalulekile ekuthuthukiseni isimo sikavithamini D. Labo abanemelanin eyengeziwe [isikhumba esimnyama] kudingeka bahlale elangeni isikhathi eside ngoba kuba nzima ukuba imisebe ingene esikhunjeni. “

Ochwepheshe batusa i-sunscreen ukuvikela umdlavuza wesikhumba ngenkathi ungaphandle isikhathi eside, okungenza kube nzima ukuthola uvithamini D owanele ekukhanyeni kwelanga, ikakhulukazi ebusika.

Futhi ukuhlupheka ngenxa yokuntuleka kwevithamini D kukhula phakathi kwamaqembu athile ngezinga eliphakeme, kuhlanganise nabantu abanesikhumba esimnyama, asebekhulile, nabantu abachayeka kancane elangeni.

Ukuhlolwa kwegazi kungenziwa ukuze kubhekwe amazinga akho kavithamini D bese uchwepheshe wezokwelapha angaluleka ngesinyathelo esingcono kakhulu.
