Mafuta emuorivhi anoita seanokwanisa kudzivirira tsinga dzeropa kubva kune zvinokuvadza zvezvinhu zvakasvibiswa uye kusvibiswa kwemhepo, nokudaro kudzivirira matambudziko emwoyo. Muchidzidzo, masayendisiti eAmerica akawana kuti mafuta emuorivhi akadzivirira zvidzidzo kubva kune zvakajairwa mhedzisiro yezvakatipoteredza oxidative kusagadzikana uye nekudaro zvinogona kubatsira mukudzivirira matambudziko emoyo uye arteriosclerosis.
Kusvibiswa kwemhepo kunokuvadza hurongwa hwemwoyo
Mahara radicals ane hukasha mamorekuru anogona kurwisa sero rega rega uye zvinotungamira kune inonzi inonzi oxidative kusagadzikana.
Kukuvadzwa kwakakonzerwa nemahara radicals hakugone kuve kwakasiyana: Oxidative kusagadzikana inowedzera njodzi yezvirwere zvakasiyana siyana, kusanganisira matambudziko emoyo negomarara. Kwete kunyange genetic zvinhu mumaseru zvakachengeteka kubva kune mahara radicals.
Chikamu chikuru cheoxidative stress yatinosangana nayo zuva rega rega inobva kumhepo: guruva rakanaka rinopinda mumuviri kuburikidza nemhepo yakasvibiswa yekufema uye inoderedza endothelial basa, pakati pezvimwe zvinhu.
Rusvingo rwemukati rwetsinga dzeropa runonzi endothelium. Kuchinja kwavo kwepathological kunobata basa mukukura kweBP uye arteriosclerosis, semuenzaniso.
Zvimwe zvekudya zvine antioxidants - zvinhu zvinoita kuti mahara radicals dzisakuvadze. Izvi zvinosanganisira polyphenols uye mavitamini C uye E.
Mafuta omuorivhi ane antioxidant effect
Chimwe chikafu chave chichizivikanwa kwenguva refu nekuda kweiyo antioxidant maitiro mafuta omuorivhi. Krill mafuta, OPC, uye astaxanthin vanoonekwawo sevabatsiri vanobatsira mukurwisa mahara radicals.
Boka rakapoteredza Dr. Haiyan Tong weUnited States Environmental Protection Agency (US Environmental Protection Agency) ikozvino yakaongorora kuti maorivhi nemafuta ehove anogona sei kudzivirira migumisiro ye oxidative stress pane endothelium.
Kuti vaite izvi, vakapatsanura 42 vatori vechikamu vane hutano hwakanaka muzvidzidzo zvevakuru mumapoka matatu.
Rimwe boka rakawedzerwa magiramu matatu emafuta omuorivhi zuva nezuva kwevhiki ina, uye rimwe boka rakatora mafuta ehove akaenzana. Yechitatu uye yekupedzisira yaive boka rekutonga, vatori vechikamu ava havana kuwana chekuwedzera.
Mafuta omuorivhi kurwisa kusvibiswa kweguruva
Pakupera kwemavhiki mana, vatori vechikamu vakasangana nemhepo yakasanganiswa nemahara radicals - kureva guruva rakanaka - mukamuri yekuyedza inodzorwa.
Masayendisiti akabva atarisa kukosha kweropa kwevatori vechikamu. Nekubatsirwa kweiyo ultrasound mudziyo, ivo vakaongororawo endothelial basa rezvidzidzo zvebvunzo.
Pakarepo mushure mekusangana nemhepo yakasvibiswa, mitsipa yeropa yevatori vechikamu vakanga vasina kuwana zvigadziro kana mafuta ehove yakangokwanisa kugadzirisa kuyerera kweropa kune zvishoma. Mhedzisiro iyi yaive isina kusimba mune avo vakagamuchira olive oil supplementation.
Maererano nekuongorora ropa, mafuta emuorivhi akakwanisawo kuderedza zvakanyanya ngozi ye thrombosis. Ukuwo, mafuta ehove akanga asina kana simba zvachose.
Mafuta omuorivhi anodzivirira sitiroko
Mukuwedzera, mafuta emuorivhi anobatsirawo kudzivirira sitiroko, maererano neongororo ye2011 yevakuru veFrance.
Vatori vechikamu vanopfuura 7,500 vakaudza Dr. Cécilia Samieri nechikwata chake kubva kuUniversité Bordeaux neFrench research Institute Institut national de la santé et de la recherche médicale nezvekushandisa kwavo mafuta emuorivhi.
Masayendisiti akatevera vatori vechikamu chidzidzo kwemakore mashanu. Vakaona kuti njodzi yesitiroko yakadzikira nemakumi mana muzana apo vatori vechikamu vaigara vachishandisa mafuta omuorivhi mukubika uye kupfeka saladhi.
Mafuta emuorivhi anodzivisa maitiro ekuputika
Tsananguro inobvira yemigumisiro inobatsira yemafuta emuorivhi pahutano hwevanhu yakapiwa naFrancisco Perez-Jimenez nevamwe vake vekuSpain Universidad de Córdoba.
Vakaona kuti mafuta emuorivhi akachinja maitiro e98 majini mune varwere vane metabolic syndrome. Izvi zvaisanganisira majini akasiyana-siyana anokurudzira maitiro ekuzvimba mumuviri uye nekudaro kuwedzera njodzi yezvirwere zvemoyo, pakati pezvimwe zvinhu.
Kuti ubatsirwe zvakanyanya sezvinobvira kubva pamigumisiro yakanaka yemafuta emuorivhi, unofanirwa kuve nechokwadi chokuti unotenga mhandara yepamusoro-soro kana mafuta emuorivhi ekuwedzera kubva mukurima kwekurima.
