Isifundo se-Pilot Siphakamisa ukuthi i-Tomato Powder inezinzuzo eziphakeme zokubuyisa umzimba ku-Lycopene

Phakathi kwezithako ezithandwayo zokudla okunempilo ezisetshenziselwa ukwengeza ukuvuselelwa kokuzivocavoca ngabasubathi, i-lycopene, i-carotenoid etholakala kutamatisi, isetshenziswa kabanzi, ngocwaningo lomtholampilo okufakazela ukuthi izithasiselo ezihlanzekile ze-lycopene iyi-antioxidant enamandla enganciphisa i-lipid peroxidation yokuzivocavoca (indlela lapho ama-radicals amahhala alimaza amaseli "ngokuntshontsha" ama-electron kusuka kuma-lipids kulwelwesi lweseli).

Ocwaningweni olusha lokushayela indiza, olushicilelwe ku-Journal of the International Society of Sports Nutrition, abacwaningi bahlose ukuphenya ngezinzuzo ze-antioxidant ze-lycopene, kepha ikakhulukazi, ukuthi bahlangana kanjani ne-tomato powder, isengezo sotamatisi esiseduze nakho konke ukudla okuqukethe hhayi i-lycopene kuphela kepha iphrofayili ebanzi yama-micronutrients nezinto ezahlukahlukene zokuphilayo.

Esifundweni esingahleliwe, esenziwe izimpumputhe eziphindwe kabili, abagijimi besilisa abaqeqeshwe kahle abangu-11 bathola izivivinyo ezintathu zokuzivocavoca umzimba ngemuva kwesonto lokunezelwa ngophawuda katamatisi, kwabe sekuhambisana ne-lycopene, kwase kuba yi-placebo. Amasampula egazi amathathu (okuyisisekelo, ukungenisa ngemuva, kanye nokuvivinya umzimba) athathwe kwisengezo ngasinye esisetshenzisiwe, ukuze kuhlolwe umthamo ophelele we-antioxidant nokuhlukahluka kwe-lipid peroxidation, njenge-malondialdehyde (MDA) ne-8-isoprostane.

Kubasubathi, utamatisi impuphu ithuthukise inani eliphelele lama-antioxidant ngo-12%. Ngokuthakazelisayo, ukwelashwa kwe-tomato powder nakho kwaholela ekukhuphukeni okuphansi kakhulu kwe-8-isoprostane uma kuqhathaniswa nakho kokubili ukwesekwa kwe-lycopene kanye ne-placebo. Impuphu yetamatisi iphinde yehlise kakhulu ukuzivocavoca okuphelele kwe-MDA uma kuqhathaniswa ne-placebo, noma kunjalo, akukho mehluko onjalo okhonjisiwe phakathi kwezindlela zokwelashwa kwe-lycopene ne-placebo.

Ngokuya ngemiphumela yocwaningo, ababhali baphetha ngokuthi izinzuzo ezinkulu kakhulu zikatamatisi powder ezinamandla okulwa ne-antioxidant kanye ne-peroxidation ebangelwa ukuzivocavoca kungenzeka zilethwe ukuxhumana okuhlangene phakathi kwe-lycopene nezinye izakhamzimba ezincibilikayo, kunokuvela kwi-lycopene endaweni ecezile ifomethi.

"Sithole ukuthi i-1-week supplementation ne-tomato powder yakhulisa ngokuphelele umthamo we-antioxidant futhi yayinamandla kakhulu uma iqhathaniswa nokwengezwa kwe-lycopene," kusho abalobi besifundo. “Lezi zindlela ze-8-isoprostane ne-MDA zisekela umbono wokuthi esikhathini esifushane, utamatisi impuphu, hhayi i-synthetic lycopene, inamandla okunciphisa i-lipid peroxidation yokuzivocavoca. I-MDA iyi-biomarker ye-oxidation yamachibi aphelele e-lipid kodwa i-8-isoprostane ingeye-F2-isoprostane class futhi iyi-biomarker enokwethenjelwa yokuphendula okubangelwa yi-radical ekhombisa ngqo uketshezi kwe-arachidonic acid. ”

Ngobufushane besikhathi sokutadisha, ababhali bacabanga ukuthi, noma kunjalo, ukuthi irejimeni le-lycopene lesikhathi eside lingaholela ezinzuzweni ezinamandla zokulwa ne-antioxidant yesakhi esizimele, ngokuhambisana nezinye izifundo ezenziwa isikhathi esingamasonto ambalwa . Noma kunjalo, utamatisi ophelele unamakhemikhali amakhemikhali angathuthukisa imiphumela ezuzisayo ekusebenzisaneni ngokuqhathaniswa nenhlanganisela eyodwa, kusho abalobi.
