Yintoni Okufanele Ndiyazi Ngayo?
I-vitamin C isondlo idlalwa njengendlela yokukhusela ngokwemvelo kwiimeko ezininzi zezempilo, ezifana nebandayo . Kodwa ngoxa uphando lubonisa ukuba ukuquka i-vitamin C eyaneleyo ekudleni kwakho kunokukhusela kwiinkalo ezithile zempilo, kukho ukungabikho kobungqina benzululwazi ukuxhasa ukusetyenziswa kwe-vitamin C.
Ukusetyenziswa kweeVitamin C
Efunyanwe ngokwemvelo kwiziqhamo ezininzi kunye nemifuno, i-vitamin C iyimfuneko ekwenzeni i-collagen, ukuphulukisa isilonda, kunye nokulungiswa nokugcinwa kwe-cartilage, amathambo namazinyo.
Ngenye iyeza, i-vitamin C isongezelelo inikeza iinzuzo ezinokuxhatshazwayo kwaye ixelwe ukukunceda le miqathango yempilo elandelayo:
- kubanda
- i-asthma
- bronchitis
- isifo senhliziyo
- neengxaki
- glaucoma
- igazi elonyukayo
- Isifo sikaParkinson
Abanye abaxhasayo bathi i-vitamin C yongezelela ukukhusela umkhuhlane, kunye nokunceda ekukhuselweni komhlaza.
Izibonelelo zezempilo zeeVitamin C:
Okwangoku, izifundo kwimiphumo yempilo ye-vitamin C zongeze iziphumo ezidibeneyo. Nanku ukukhangela kwezinye iziphumo eziphambili:
1) Iibhokhwe
Kuhlalutyo luka-2007 lwezilingo ezingama-30 (ezibandakanya abantu abangama-11,350), abaphandi baphetha ngelithi i-vitamin C isongezelelo ayinakunceda ukulwa nokubanda kwiindawo eziqhelekileyo. Nangona kunjalo, abalobi bahlaziyi bayiqonda ukuba i-vitamin C isongezelelo ingaba yinzuzo kwabanye abantu abahlala kwiindawo ezibandayo kakhulu okanye abantu abavelele kwixesha elifutshane lokuzilolonga umzimba (njengabagijimi bezemidlalo).

2) Izifo zentliziyo
Ukuthatha izithako ze-vitamin C kunokunciphisa umngcipheko weziganeko eziphambili ze-cardiovascular, ngo-2008 uphando lwe-14,641 oogqirha abanamadoda (abaneminyaka engama-50 ubudala nangaphezulu kwisiqalo sokufunda). Ngokomyinge wesibhozo iminyaka, amalungu okufunda athatha indawo ye-placebo okanye i-500 mg ye-vitamin C kwifom yokufumana imihla ngemihla.
(Ukongeza, iqela lokuncedisa lithatha i-400 IU ye-vitamin E imihla ngemihla.) Iziphumo zophando zibonise ukuba i-vitamin E okanye i-vitamin C ayinayo imiphumo ebalulekileyo kwiziganeko ezinkulu zentliziyo, njenge- stroke ne-heart attack.

3) I cancer
Uphando olupapashwe ngo-2009, abafazi abayi-8 171 bathatha i-placebo okanye i-500 mg ye-vithamini C kwifom yokufumana imihla ngemihla (kunye ne-vitamin E kunye ne-beta carotene yonke imihla) kwiminyaka eyi-9.4. Iziphumo zokufunda zibonise ukuba ukongezwa nge-vitamin C, i-vitamin E, okanye i-beta carotene ayizange incede ukunqanda umdlavuza.
Ngaphezu koko, uphando olwenziwa ngo-2008 lwama-77 721 amadoda namabhinqa (abaneminyaka engama-50 ukuya kuma-76) afumanisa ukuba ukusetyenziswa kwexesha elide le-vitamin C, akuzange kunciphise umngcipheko womhlaza wamaphaphu. Kwaye ngo-2004 ukuphononongwa kwezifundo ezili-14 kwi-antioxidant supplements kunye nokuthintela isifo somhlaza wesisu - kubandakanya iilingo ezine ezibandakanya izongezelelo ze-vitamin C - abaphandi abafumananga ubungqina bokuthi i-antioxidant supplements ikhusele umdlavuza wesisu.

Imijelo
Nangona i-vitamin C ibonwa ngokukhuselekileyo, amanani aphezulu angakhokelela kwimiphumo emibi, kubandakanywa namatye entsobe, isifo sohudo esinamandla, kunye nesiphithiphithi. Ngaphezu koko, uphando lwe-2008 lubonisa ukuba ukuthatha i-vitamin C ngexesha lokunyanga umhlaza kunokunciphisa ukusebenza kwezilwanyana ezithile ze- chemotherapy .
Izibonelelo azange zivavanywe ukhuseleko kwaye ngenxa yokuba izongezo zokutya zikhululekile kakhulu, umxholo weemveliso ezithile zingahluka kwizinto ezichaziweyo kwilebula yomkhiqizo. Kwakhona ugcine ukhumbule ukuba ukhuseleko lwezongezelelo kwabasetyhini abakhulelweyo, oomama abangabongikazi, abantwana kunye nalabo abanezifo zonyango okanye abo bathabatha imishanguzo ayilwanga.

Ukusebenzisa iVithamini C yezeMpilo
Ngenxa yokunqongophala kwenkxaso yesayensi yeenzuzo zezempilo ze-vitamin C, kubalulekile ukuba ungathembeli kwimveliso yevithamini C njengonyango oluphambili lwaluphi na uhlobo lwempilo. Ukuze ufumane i-vitamin C eyaneleyo imihla ngemihla, jonga kuqala kwimithombo yokutya njenge-citrus, i-strawberries, utamatisi, i-pepper, imifuno eluhlaza kunye ne-cantaloupe.
Ukuba ufuna ukunyanga okanye ukuthintela imeko ethile kunye ne-vitamin C isongezelelo - okanye nayiphi na isongezelelo sokutya - qi niseka ukuba udibane nodokotela wakho ngaphambi kokuba uqale irejimen yakho yokongeza. Gcina ukhumbule ukuba elinye iyeza kufuneka lingasetyenziswanga njengenxalenye yokunyamekela okuqhelekileyo. Ukuziphathela imeko kunye nokuphepha okanye ukulibazisa ukunakekelwa okuqhelekileyo kunokuba nemiphumo emibi.
