Amafutha omnqumo abonakala ekwazi ukuvikela imithambo yegazi emiphumeleni eyingozi yezinhlayiyana nokungcoliswa komoya, ngaleyo ndlela avimbele izinkinga zenhliziyo nemithambo yegazi. Ocwaningweni, ososayensi baseMelika bathola ukuthi amafutha omnqumo avikela izihloko zokuhlolwa emiphumeleni evamile yokucindezeleka kwe-oxidative yemvelo futhi ngaleyo ndlela angaba nomthelela ekuvimbeleni izinkinga zenhliziyo kanye ne-arteriosclerosis.
Ukungcoliswa komoya kulimaza isimiso senhliziyo nemithambo yegazi
Ama-radicals wamahhala angama-molecule anolaka angahlasela ingqamuzana ngalinye futhi aholele kulokho okubizwa ngokuthi i-oxidative stress.
Umonakalo odalwe ama-radicals wamahhala awukwazanga ukuhluka kakhulu: Ukucindezeleka okwenziwe nge-oxidative kwandisa ingozi yezifo ezihlukahlukene, kuhlanganise nezinkinga zenhliziyo nomdlavuza. Ngisho nezakhi zofuzo kumaseli aziphephile kuma-radicals mahhala.
Ingxenye enkulu yokucindezeleka okwenziwe nge-oxidative esivezwa kukho nsuku zonke ivela emoyeni: uthuli olucolile lungena emzimbeni ngomoya ongcolile wokuphefumula futhi lunciphise umsebenzi wokugcina, phakathi kwezinye izinto.
Udonga lwangaphakathi lwemithambo yegazi lubizwa ngokuthi i-endothelium. Ukushintsha kwabo kwe-pathological kudlala indima ekuthuthukiseni umfutho wegazi ophezulu kanye ne-arteriosclerosis, isibonelo.
Okunye ukudla kuqukethe ama-antioxidants - izinto ezenza ama-radicals mahhala angabi nangozi. Lezi zihlanganisa ama-polyphenols namavithamini C no-E.
Amafutha omnqumo anomphumela we-antioxidant
Okunye ukudla osekwaziwa kudala ngezakhiwo zakho zokulwa ne-antioxidant amafutha omnqumo. Amafutha e-krill, i-OPC, ne-astaxanthin nawo abhekwa njengabasizi abaphumelelayo ekulweni nama-radicals mahhala.
Ithimba elizungeze uDkt. Haiyan Tong we-United States Environmental Protection Agency (US Environmental Protection Agency) manje seliphenye ukuthi amafutha omnqumo nawenhlanzi angavimbela kangakanani imiphumela yokucindezeleka okwenziwe nge-oxidative ku-endothelium.
Ukwenza lokhu, bahlukanise ababambiqhaza bocwaningo lwabantu abadala abangama-42 baba ngamaqembu amathathu.
Elinye iqembu lanezelwa ngamagremu amathathu amafutha omnqumo nsuku zonke amasonto amane, futhi elinye iqembu lathatha inani elifanayo lamafutha ezinhlanzi. Owesithathu nowokugcina kwakuyiqembu lokulawula, laba ababambiqhaza abatholanga ukwesekwa.
Amafutha omnqumo ngokumelene nokungcoliswa kothuli olucolekile
Ekupheleni kwamasonto amane, ababambiqhaza bavezwe emoyeni oxutshwe nama-radicals mahhala - okungukuthi uthuli oluhle - ekamelweni lokuhlola elilawulwayo.
Ososayensi babe sebehlola amanani egazi labahlanganyeli. Ngosizo lwedivayisi ye-ultrasound, baphinde bahlola umsebenzi we-endothelial wezifundo zokuhlolwa.
Ngokushesha ngemva kokuchayeka emoyeni ongcolile, imithambo yegazi yabahlanganyeli ababengazange bathole noma yiziphi izithako noma amafutha ezinhlanzi bakwazi ukulungisa ukugeleza kwegazi ngezinga elilinganiselwe kuphela. Lo mphumela wawubuthakathaka kakhulu kulabo abathola i-olive oil supplementation.
Ngokusho kokuhlaziywa kwegazi, amafutha omnqumo akwazi ukunciphisa kakhulu ingozi ye-thrombosis. Ngakolunye uhlangothi, amafutha ezinhlanzi ayengenawo nhlobo umphumela.
Amafutha omnqumo avimbela isifo sohlangothi
Ngaphezu kwalokho, amafutha omnqumo nawo asiza ukuvimbela isifo sohlangothi, ngokusho kocwaningo lwango-2011 lwabantu abadala baseFrance.
Abahlanganyeli abangaphezu kuka-7,500 bazise uDkt. Cécilia Samieri nethimba lakhe abavela e-Université Bordeaux kanye nesikhungo socwaningo saseFrance i-Institut national de la santé et de la recherche médicale mayelana nokusebenzisa kwabo uwoyela we-olive.
Ososayensi balandele ababambiqhaza bocwaningo iminyaka emihlanu. Bathole ukuthi ingozi yokushaywa unhlangothi yehle ngamaphesenti angamashumi amane lapho abahlanganyeli bevame ukusebenzisa amafutha omnqumo kokubili ekuphekeni nasekugqokeni kwesaladi.
Amafutha omnqumo avimbela izakhi zofuzo ezivuthayo
Incazelo engenzeka yemiphumela enenzuzo yamafutha omnqumo empilweni yomuntu yanikezwa uFrancisco Perez-Jimenez nozakwabo base-Universidad de Córdoba yaseSpain.
Bathole ukuthi amafutha omnqumo aguqule umsebenzi wezakhi zofuzo ze-98 ezigulini ezine-metabolic syndrome. Lokhu kwakuhlanganisa nezakhi zofuzo ezihlukahlukene ezikhuthaza izinqubo zokuvuvukala emzimbeni futhi ngaleyo ndlela zandise ingozi yezifo zenhliziyo, phakathi kwezinye izinto.
Ukuze uzuze ngangokunokwenzeka emiphumeleni emihle yamafutha omnqumo, kufanele uqiniseke ukuthi uthenga amafutha omnqumo asezingeni eliphezulu noma amafutha omnqumo e-extra-virgin kusuka ekulimeni kwemvelo.
