Yintoni iBeta Carotene?

I-Beta-carotene sisidali-bala esifumaneka kwizityalo esizinika umbala wazo. Igama elithi beta-carotene lithatyathwe kwigama lesiLatini lekherothi. Inika iziqhamo kunye nemifuno etyheli kunye neorenji imibala yazo etyebileyo. IBeta-carotene ikwasetyenziselwa ukufaka imibala kukutya okufana nemargarine.

Emzimbeni, i-beta-carotene iguqulwa ibe yivithamin A (retinol). Sifuna ivithamin A ukuze sibe nombono omhle kunye nempilo yamehlo, amajoni omzimba aqinileyo, kunye nolusu olusempilweni kunye nenwebu zemifinya. Ukuthatha iidosi ezinkulu ze-vitamin A kunokuba yityhefu, kodwa umzimba wakho uguqula kuphela i-vitamin A eninzi kwi-beta-carotene njengoko ifuna. Oko kuthetha ukuba i-beta-carotene ithathwa njengomthombo okhuselekileyo wevithamini A. Nangona kunjalo, i-beta-carotene eninzi inokuba yingozi kubantu abatshayayo. (Ukufumana isixa esikhulu sevithamin A okanye i-beta-carotene ekutyeni, hayi kwizongezo, kukhuselekile.)

IBeta-carotene yi-antioxidant. Ikhusela umzimba kwiimolekyuli ezonakalisayo ezibizwa ngokuba ziiradicals zasimahla. Iiradicals zasimahla zonakalisa iiseli ngenkqubo eyaziwa ngokuba yi-oxidation. Ngokuhamba kwexesha, lo monakalo unokukhokelela kwinani lezifo ezingapheliyo. Kukho ubungqina obulungileyo bokuba ukutya okungaphezulu kwe-antioxidants ekutyeni kunceda ukomeleza amajoni akho omzimba, ukukhusela kwi-radicals yasimahla, kwaye kunokwehlisa umngcipheko wesifo sentliziyo kunye nomhlaza. Kodwa umcimbi unzima ngakumbi xa kuziwa ekuthatheni izongezo ze-antioxidant.

 

IiNzuzo zeMpilo zeBeta-Carotene

Yehlisa uMngcipheko weSifo seCardiovascular

I-Beta-carotene yi-antioxidant elwa nesifo efunyenwe ukunciphisa umngcipheko wesifo senhliziyo. Uphando lufumene ukuba ukutya okutyebileyo kwi-beta-carotene kunokunceda ukukhusela iingxaki ezinxulumene nentliziyo kuba i-beta-carotene imiphumo ye-antioxidant inceda ukukhusela i-oxidation ye-low-density lipoprotein (LDL), okanye "imbi," i-cholesterol.

Ithoba inqanaba lokuLahleka koMbono

Iingcebiso zobudala bokuba iminqathe ilungile emehlweni akho inokuba nenyaniso ethile. I-Beta-carotene inokukhusela abantu abadala ekuphuhlisweni kwe-macular degeneration (AMD) enxulumene neminyaka, yinto eqhelekileyo kunye nengapheliyo (ehlala ixesha elide) imeko yamehlo eyenza ukulahlekelwa ngokuthe ngcembe kombono ophakathi.

Yandisa inkqubo yoKhuseleko lwamajoni omzimba

I-Vitamin A inemisebenzi emininzi emzimbeni, kuquka ukuxhasa ukhuselo lomzimba. Njenge-provitamin A carotenoid, i-beta-carotene inceda ukukhusela nokuqinisa imisebenzi ye-immune system. Inceda amajoni omzimba ukunceda umsebenzi wesisu, ukulwa nosulelo, ukuxhasa impilo yokuzala, kunye nokuqinisekisa ukukhula okufanelekileyo kunye nophuhliso.

Inganceda ukwehlisa uMngcipheko woMhlaza

I-Beta-carotene ibonise isithembiso ekunciphiseni umngcipheko weentlobo ezahlukeneyo zomhlaza, kuquka isifuba, i-prostate, i-colon, kunye nomhlaza wesikhumba .3 Imiphumo ye-antioxidant ye-beta-carotene icingelwa ukuba iyona nto ijongene nokunciphisa ingozi. Nangona kunjalo, abaphandi baqaphela ezinye i-antioxidants (ezifana ne-lycopene) ezifumaneka kukutya okufanayo nazo zinokuba negalelo kule mpembelelo.

Uyithatha njani iBeta-carotene

Ungathatha beta-carotene njengesongezelelo kwithebhulethi, ulwelo, i-capsule, okanye i-gummy form. Xa ithathwa njengesongezelelo, i-beta-carotene inokunceda ukukhusela i-cholesterol ye-LDL ene-oxidized, ukuphucula umsebenzi we-antioxidant, kunye nokwandisa ukuveliswa kweeseli zomzimba.

 

 

Ngaba iBeta-Carotene ikhuselekile?

IBeta-carotene ihlelwa “njengesaziwa njengekhuselekile” (GRAS) yi-US Food and Drug Administration (FDA).

Ulawulo lokutya kunye neziyobisi lwase-US. IKomiti eKhethekileyo ye-GRAS Substances (SCOGS) Uluvo: Carotene (beta-carotene).

Ngelixa i-beta-carotene ifunyenwe inciphisa umngcipheko weentlobo ezithile zomhlaza, olunye uphando lufumanise ukuba ukuthatha iidosi eziphezulu ze-beta-carotene izongezelelo kunokunyusa umngcipheko womhlaza wemiphunga nokufa phakathi kwabantu abatshayayo, abasebenzisa ukutshaya, okanye abaye bachanabeka kwi-asbestos.

Kukhuselekile ukuba abantu bayo nayiphi na iminyaka ukuba bathathe i-beta-carotene. Abantu abakhulelweyo okanye abancancisayo banokuthatha i-beta-carotene. Nangona kunjalo, ukuba ukhulelwe okanye uncancisa, soloko uthetha nomboneleli wezempilo ngaphambi kokuba wongeze nayiphi na isongezelelo esitsha kwindlela yakho yesiqhelo.

 

 

Ngaba ungathatha iBeta-Carotene eninzi kakhulu?

Nakuba beta-carotene izongezo zithathwa njenge-GRAS yi-FDA, ukutya okuninzi kuyo kunokubangela okwethutyana ukuba ulusu lwakho lujike lube tyheli. Ukuthintela oku, qiniseka ukuba awuyityi kakhulu i-beta-carotene ekutyeni okanye kwizongezelelo.

Akukho mda uphezulu obekwe yi-FDA kwi-beta-carotene intake. Injongo yokuhlala ngaphakathi kweemali ze-RDA ze-provitamin A carotenoids (i-900 mcg RAE yamadoda kunye ne-700 mcg RAE yabasetyhini), okanye uthethe nomboneleli wezempilo malunga nokuba ingakanani i-beta-carotene ekulungeleyo.

 

 

izigqibo

I-Beta-carotene yi-orenji-bomvu ye-carotenoid pigment efumaneka kukutya okunemibala eqaqambileyo njengeminqathe kunye ne-broccoli. Ikwafumaneka njengesongezelelo.

Isityebi kwiprovitamin A, i-beta-carotene inemisebenzi enamandla ye-antioxidant enceda ukunciphisa umngcipheko wezifo ezifana nesifo senhliziyo kunye neentlobo ezithile zomhlaza. I-Beta-carotene isenokunceda ukucothisa isantya sokuphulukana nombono kwabo bane-AMD. Ikwaluncedo ekusebenzeni ngokufanelekileyo kwamajoni omzimba.
