Ingabe i-Vitamin A (Retinol) ingayandisa ingozi yomdlavuza?

Amaphuzu avelele

Izifundo eziningi zemitholampilo zihlaziye ukuhlotshaniswa kwamazinga kavithamini A (retinol) nobungozi bomdlavuza. Izinga le-Vitamin A (retinol) lalihlotshaniswa kahle nengozi yomdlavuza wendlala yesinye, njengoba kuhlolwa inani elikhulu leziguli ezinomdlavuza. Lokhu kubonisa ukuthi ukusetshenziswa kwezithako zamavithamini ngokweqile ukuze kusekelwe impilo nokuphila kahle kungase kungangezi ngempela ukubaluleka kwethu futhi kungase kube namandla okubangela umonakalo njengokwandisa ingozi ye-prostate. umdlavuza.

Uvithamini A neCancer

I-Vitamin A noma i-Retinol iyisakhi somzimba esincibilikayo esinamafutha esinezinzuzo ezahlukahlukene zezempilo kubandakanya okulandelayo:

• Isekela umbono ojwayelekile
• Isekela isikhumba esinempilo
• Usekela ukukhula nokuthuthukiswa kwamaseli
• Thuthukisa ukusebenza komzimba
• Sekela ukuzala nokukhula kombungu

Ukuba ngumsoco obalulekile, uVitamin A akhiqizwa ngumzimba womuntu futhi utholakala ekudleni kwethu okunempilo. Kutholakala kakhulu emithonjeni yezilwane njengobisi, amaqanda, ushizi, ibhotela, isibindi kanye namafutha wesibindi senhlanzi ngendlela ye-retinol, uhlobo olusebenzayo lwe-Vitamin A, nasemithonjeni yezitshalo njenge-carrot, i-broccoli, ubhatata, obomvu upelepele wensimbi, isipinashi, upopoya, umango nethanga ngendlela yama-carotenoids, aguqulwa abe yi-retinol ngumzimba womuntu ngesikhathi sokugaya.

Ukusetshenziswa kwezithasiselo ze-Multivitamin kuyanda esizukulwaneni se-baby boomer esiguga ngezinzuzo zezempilo kanye nokusekela impilo yonke. Iningi labantu likholelwa ukuthi ukuthathwa kwamavithamini aphezulu kuyi-elixir elwa nokuguga, ekhuthaza ukuzivikela komzimba kanye nokuvimbela izifo, okuthi noma kungasebenzi, ngeke kulimaze. Ngokusetshenziswa kabanzi kwamavithamini emhlabeni wonke, kuye kwaba nezifundo eziningi zomtholampilo ezibheka emuva eziye zabheka ukuhlotshaniswa kwamavithamini ahlukahlukene kanye nawo. umdlavuza indima yokuvimbela. Kule bhulogi, sibheke ngokukhethekile izifundo ezihlole ukuhlangana kwamazinga e-retinol (uvithamini A) ku-serum kanye nengozi yomdlavuza ohlukahlukene kubandakanya nomdlavuza wendlala yesinye.

I-Vitamin A (Retinol) kanye ne-Prostate Cancer Risk

Ngezansi kunesifinyezo sezinye zalezi zifundo nokutholakele kwazo okubalulekile:

• Ukuhlaziywa okuhlanganisiwe kwezifundo zemitholampilo ezihlukene eziyi-15 ezanyatheliswa kuyi-American Journal of Clinical Nutrition ngo-2015, kwabheka amacala angaphezu kuka-11,000, ukuze kunqunywe ukuhlangana kwamazinga amavithamini kanye umdlavuza ingozi. Kulo sayizi wesampula omkhulu kakhulu, amazinga e-retinol ayehlotshaniswa kahle nengozi yomdlavuza we-prostate (Ukhiye TJ et al, Am J Clin Nutr., 2015).
• Ukuhlaziywa kokubukwa kwamasampuli angaphezu kwama-29,000 avela ocwaningweni lokuvikela umdlavuza lwe-alpha-tocopherol, beta-carotene olwenziwe yiNational Cancer Institute (NCI), iNational Institute of Health (NIH), e-USA, kubikwe ukuthi kulandelwa iminyaka emithathu, amadoda ukuhlushwa okuphezulu kwe-serum retinol (Vitamin-A) bekuneengozi ephezulu yomdlavuza wendlala yabesilisa (UMondul AM et al, Am J Epidemiol, 2011).
• Ukuhlaziywa kwakamuva kwe-NCI efanayo eqhutshwa yi-alpha-tocopherol, ucwaningo lokuvimbela umdlavuza we-beta-carotene lwabahlanganyeli abangaphezu kuka-29,000 phakathi kuka-1985-1993 nokulandelela ku-2012, kuqinisekisile okutholakele kwangaphambilini kokuhlangana kwe-serum retinol ephezulu engozini eyandayo. wendlala yesinye umdlavuza. I-serum retinol ephezulu ayizange ihlotshaniswe nengozi yomdlavuza futhi ibhekwa njengenciphisa ingozi yomdlavuza wesibindi namaphaphu, kodwa kuzo zonke izifundo eziningi kube nokuhlobana okuhle okubonwe phakathi kwamazinga e-serum Retinol (Vitamin A) kanye nengozi ephakeme yomdlavuza wendlala yesinye.UHada M et al, Am J Epidemiol, 2019).

Isiphetho

Lezi zifundo zikhomba ukuthi ukudla okuphezulu kwe-Vitamin A supplements kuhlotshaniswa nengozi eyengeziwe ye-prostate umdlavuza. Isho ukuthini le datha kithi? Kubonisa ukuthi ukweqisa kwezithako zamavithamini ukusekela impilo nokuphila kahle kungase kungangezi ngempela inani elikhulu kithi futhi kungase kube namandla okubangela umonakalo. Okungcono kithi ukuthola umthombo wamavithamini namaminerali ngemithombo yemvelo kanye nokudla okunempilo okunomsoco.

Ukudla okudlayo nokuthi yikuphi okunezelayo okwenzayo yisinqumo osithathayo. Isinqumo sakho kufanele sifake ukucutshungulwa kwezakhi zofuzo zomdlavuza, okuwumdlavuza, ukwelashwa okuqhubekayo kanye nezithasiselo, noma yikuphi ukungezwani komzimba, imininingwane yokuphila, isisindo, ubude nemikhuba.

Ukuhlelela okunomsoco komdlavuza kusuka ku-addon akususelwa ekusesheni kwe-inthanethi. Kwenzela wena ukuthathela izinqumo ngokuya ngesayensi yamangqamuzana eyenziwe ososayensi bethu nonjiniyela be-software. Kungakhathalekile ukuthi ngabe uyakukhathalela ukuqonda okuyisisekelo kwamakhemikhali amakhemikhali noma cha - wokuhlelela umsoco ukuhlela lokho kudinga ukuqonda.

Qalisa MANJE ngokuhlela kwakho okunomsoco ngokuphendula imibuzo egameni lomdlavuza, ukuguquka kwezakhi zofuzo, ukwelashwa okuqhubekayo kanye nezithasiselo, noma yikuphi ukungezwani komzimba, imikhuba, indlela yokuphila, iqembu lobudala nobulili.

Iziguli ezinomdlavuza ngokuvamile kufanele zibhekane nokuhlukile imiphumela emibi ye-chemotherapy okuthinta ikhwalithi yempilo yabo futhi babheke ezinye izindlela zokwelapha umdlavuza. Ukuthatha ukudla okunomsoco nezithasiselo ezisuselwa ekucabangeni kwesayensi (ukugwema ukuqagela nokukhetha okungahleliwe) yikhambi elingcono kakhulu lemvelo lomdlavuza nemiphumela emibi ehlobene nokwelashwa.

• Ingabe ukudla i-Vitamin A kunciphisa ubungozi Bomdlavuza Wesikhumba?
• Ingabe amavithamini namavithamini amaningi alungele umdlavuza?
• Inhlangano edidayo yokusebenzisa iVithamin E Supplement kanye neBrain Cancers
• Ngabe Ukudla Kwe-Supplement Supplement Kuyasebenza Ngesikhathi Semiphumela Yokusinda Kwe-Chemotherapy Impact Yeziguli Zomdlavuza Webele?
