Ukusebenza kahle kwembewu yamagilebhisi kwatholakala ngendaba "yokugaywa kabusha kwemfucuza".
Umlimi owenza iwayini wayengafuni ukusebenzisa imali eningi esebenzelana nokusaphazwa okungaka kwembewu yamagilebhisi, ngakho wacabanga ukuyitadisha. Mhlawumbe wayezothola ukubaluleka kwayo okukhethekile. Lolu cwaningo lwenze imbewu yamagilebhisi yaba isihloko esishisayo embonini yokudla kwezempilo.
Ngoba uthole i-bioactive antioxidant "proanthocyanidins" embewini yamagilebhisi.
Ama-anthocyanins nama-proanthocyanidins
Uma kukhulunywa nge-proanthocyanidins, kuyadingeka ukusho ama-anthocyanins.
◆I-Anthocyanin iwuhlobo lwento ye-bioflavonoid, uhlobo lwe-pigment yemvelo encibilika emanzini, etholakala kakhulu kuma-angiosperms, phakathi kwawo atholakala kakhulu kumajikijolo afana namajikijolo ama-goji amnyama, ama-blueberries nama-mulberry.
◆Proanthocyanidins wuhlobo lwe-polyphenol ehambisana nenhlanganisela eyaziwayo, i-resveratrol, evame ukutholakala esikhumbeni samagilebhisi nembewu.
Nakuba zihluka ngomlingiswa oyedwa kuphela, ziyizinto ezihluke ngokuphelele.
Umsebenzi oyinhloko we-proanthocyanidins ukwenza njengama-antioxidants
I-Antioxidation ngokuyinhloko ibhekisela ekuvinjweni kokusabela kwe-oxidation ngaphakathi komzimba. Ukusabela kwe-oxidation kukhiqiza ama-radicals mahhala, angaqala impendulo edala ukulimala kwamaseli kanye ne-apoptosis, ngaleyo ndlela kuholele ekugugeni.
Ama-Antioxidants anganciphisa ama-radicals mahhala emizimbeni yethu, avimbele ukulimala kwamaseli kanye ne-apoptosis, futhi ngaleyo ndlela abambe iqhaza ekubambezeleni ukuguga.
Njengoba i-proanthocyanidins ekhishwe embewini yamagilebhisi inemiphumela ye-antioxidant, kungani-ke singakwazi ukudla imbewu yamagilebhisi ngokuqondile?
Ngokwemiphumela yocwaningo, okuqukethwe kwe-proanthocyanidins embewini yamagilebhisi kulinganiselwa ku-3.18mg ku-100g. Njenge-antioxidant evamile, kunconywa ukuthi umthamo wansuku zonke we-proanthocyanidin ube ngu-50mg.
Uma uguquliwe, umuntu ngamunye udinga ukudla u-1,572g wembewu yamagilebhisi nsuku zonke ukuze azuze umphumela we-antioxidant. Ngaphezu kwamakhilogremu amathathu embewu yamagilebhisi, ngikholwa ukuthi kunzima kunoma ubani ukuwadla...
Ngakho-ke, uma ufuna ukwengeza i-proanthocyanidins, kusebenza kahle kakhulu ukuthatha izithasiselo zezempilo ezihlobene nembewu yamagilebhisi.
Ukukhishwa kwembewu yamagilebhisi
Iwusizo empilweni yenhliziyo, isikhumba nobuchopho
◆Yehlisa umfutho wegazi
Ama-antioxidants ekukhishweni kwembewu yamagilebhisi (okuhlanganisa i-flavonoid, i-linoleic acid ne-phenolic proanthocyanidins) asiza ukuvimbela ukulimala kwemithambo kanye nomfutho wegazi ophezulu.
Ucwaningo lukhombisa ukuthi imbewu yamagilebhisi ekhishwayo ingasiza ekwandiseni imithambo yegazi futhi ingasiza iziguli ezine-metabolic syndrome ekwehliseni umfutho wegazi.
◆Thuthukisa ukungasebenzi kahle kwe-venous
Ukukhishwa kwembewu yamagilebhisi kusiza ukuqinisa ama-capillaries, imithambo yegazi kanye nemithambo, futhi kuthuthukise ukujikeleza kwegazi.
Amaphesenti angamashumi ayisishiyagalombili eziguli ezinokuntuleka kwe-venous okungapheli abike ukuthi izimpawu zabo ezihlukahlukene ziye zaba ngcono ngemva kokuthatha ama-proanthocyanidin izinsuku eziyishumi, ngokuncipha okukhulu kobuthuntu, ukulunywa nobuhlungu.
◆Qinisa amathambo
Ukukhishwa kwembewu yamagilebhisi kungathuthukisa ukuguquguquka kwamalunga, kukhuthaze ukwakheka kwamathambo, kwandise amandla amathambo, futhi kunciphise ingozi ye-osteoporosis, ukuphuka nezinye izifo.
◆Thuthukisa ukuvuvukala
I-University of Maryland Medical Centre yaveza ukuthi iziguli ezathatha ama-milligrams angu-600 embewu yamagilebhisi ekhishwa nsuku zonke ngemva kokuhlinzwa futhi zaphikelela izinyanga eziyisithupha zathola ubuhlungu obunciphile kanye nezimpawu ze-edema uma ziqhathaniswa nalezo ezithathe i-placebo.
Olunye ucwaningo lubonisa ukuthi ukukhishwa kwembewu yamagilebhisi kungavimbela ngempumelelo ukuvuvukala kwemilenze okubangelwa ukuhlala isikhathi eside.
◆Ukuthuthukisa izinkinga zesifo sikashukela
Uma kuqhathaniswa nokuphathwa kokungenelela komuntu ngamunye, inhlanganisela yokukhishwa kwembewu yamagilebhisi nokuqeqeshwa kokuzivocavoca kuphumelela kakhulu ekuthuthukiseni i-lipids yegazi, ukunciphisa isisindo, ukwehlisa umfutho wegazi kanye nokunciphisa ezinye izinkinga zesifo sikashukela.
Abacwaningi bathi, “Ukukhishwa kwembewu yamagilebhisi nokuqeqeshwa kokuzivocavoca kuyindlela elula futhi engabizi yokwelapha izinkinga zesifo sikashukela.”
◆Thuthukisa ukwehla kwengqondo
Ucwaningo lwezilwane lubonise ukuthi ukukhishwa kwembewu yamagilebhisi kunganciphisa ingcindezi ye-oxidative futhi kuvikele ukusebenza kwe-mitochondrial, ngaleyo ndlela kubuyisele emuva ukungasebenzi kahle kwe-hippocampal ebuchosheni.
Imbewu yamagilebhisi ekhishwe ingasetshenziswa ngisho njengesivimbeli noma i-ejenti yokwelapha isifo i-Alzheimer's.
