Maphunziro Oyendetsa Oyendetsa Akuwonetsa Powder wa Tomato ali ndi Ubwino Wapamwamba Wolimbitsa Thupi Lowonjezera ku Lycopene

Pakati pa zakudya zodziwika bwino zomwe zimagwiritsidwa ntchito kuti zitheke kuchita masewera olimbitsa thupi ndi othamanga, lycopene, carotenoid yomwe imapezeka mu tomato, imagwiritsidwa ntchito kwambiri, ndi kafukufuku wachipatala akuwonetsa kuti zowonjezera zowonjezera za lycopene ndi antioxidant wamphamvu yomwe ingachepetse kuchita masewera olimbitsa thupi lipid peroxidation (njira yomwe ma radicals aulere amawononga ma cell mwa "kuba" ma elekitironi kuchokera ku lipids mu nembanemba yama cell).

Mu kafukufuku watsopano woyendetsa ndege, wofalitsidwa mu Journal of the International Society of Sports Nutrition, ofufuza akufuna kufufuza ubwino wa antioxidant wa lycopene, koma makamaka, momwe amachitira motsutsana ndi ufa wa phwetekere, chowonjezera cha phwetekere pafupi ndi chiyambi chake cha chakudya chomwe chili. osati lycopene koma mbiri yotakata ya micronutrients ndi zigawo zosiyanasiyana za bioactive.

Mu phunziro la crossover lachisawawa, lopanda khungu kawiri, othamanga aamuna a 11 ophunzitsidwa bwino adayesedwa katatu pambuyo pa sabata yowonjezera ndi ufa wa phwetekere, kenako lycopene supplement, ndiyeno placebo. Zitsanzo zitatu za magazi (zoyambira, kumeza, ndi pambuyo pochita masewera olimbitsa thupi) zinatengedwa pazitsulo zilizonse zomwe zimagwiritsidwa ntchito, pofuna kuyesa mphamvu zonse za antioxidant ndi zosinthika za lipid peroxidation, monga malondialdehyde (MDA) ndi 8-isoprostane.

Kwa othamanga, ufa wa phwetekere umapangitsa mphamvu ya antioxidant ndi 12%. Chochititsa chidwi, chithandizo cha ufa wa phwetekere chinapangitsanso kuchepa kwakukulu kwa 8-isoprostane poyerekeza ndi lycopene supplement ndi placebo. Ufa wa phwetekere unachepetsanso kwambiri kuchita masewera olimbitsa thupi MDA poyerekeza ndi placebo, komabe, palibe kusiyana kotereku komwe kunawonetsedwa pakati pa mankhwala a lycopene ndi placebo.

Kutengera zotsatira za kafukufukuyu, olembawo adatsimikiza kuti phindu lalikulu kwambiri la phwetekere anali nalo pa antioxidant mphamvu komanso peroxidation yochita masewera olimbitsa thupi mwina idabwera chifukwa cha mgwirizano pakati pa lycopene ndi michere ina ya bioactive, m'malo mochokera ku lycopene pamalo akutali. mtundu.

"Tinapeza kuti 1-sabata yowonjezera ndi phwetekere ufa imawonjezera mphamvu ya antioxidant mphamvu ndipo inali yamphamvu kwambiri poyerekeza ndi lycopene supplementation," olemba kafukufukuyu anatero. "Zochita izi mu 8-isoprostane ndi MDA zimathandizira lingaliro lakuti pakapita nthawi yochepa, ufa wa phwetekere, osati lycopene wopangidwa, uli ndi mphamvu yochepetsera lipid peroxidation yochita masewera olimbitsa thupi. MDA ndi biomarker ya makutidwe ndi okosijeni m'madzi onse amadzimadzi koma 8-isoprostane ndi ya F2-isoprostane kalasi ndipo ndi biomarker yodalirika ya kachitidwe kochititsa chidwi komwe kumawonetsa makamaka makutidwe ndi okosijeni a arachidonic acid.

Ndi kufupikitsa kwa nthawi yophunzira, olembawo adaganiza kuti, komabe, njira yowonjezera yowonjezera ya lycopene ikhoza kubweretsa phindu lamphamvu la antioxidant kwa michere yomwe ili kutali, malinga ndi maphunziro ena omwe anachitika kwa milungu ingapo. . Komabe, phwetekere yonse imakhala ndi mankhwala omwe angapangitse zotsatira zopindulitsa mu synergy poyerekeza ndi gulu limodzi, olembawo adatero.
