Njengoba indaba ihamba, abashayeli bezindiza baseBrithani eMpini Yezwe Yesibili badla ujamu we-bilberry ukuze bathuthukise umbono wabo wasebusuku.Hhayi-ke, yindaba enhle...
Uma kuziwa ekuhloleni izithasiselo zokudla, inselele iwukuthola ukucaca okuthile lapho ubheka inkungu yezifundo ezingqubuzanayo, ucwaningo olungenangqondo, ukukhangisa okushisekela ngokweqile kanye nemithetho kahulumeni exegayo.Izingcaphuno ze-blueberry kanye nomzala wayo waseYurophu i-bilberry, ziyisibonelo.
Iqala ngenganekwane ekhangayo.Njengoba indaba ihamba, abashayeli bezindiza baseBrithani basebenzisa ama-bilberries ukudubula ama-fighters aseJalimane phakathi neMpi Yezwe Yesibili.Abazange babadubule ngezibhamu zabo.Bawadla.Ngendlela yejamu.Lokhu kuthiwa kuthuthukise ukubona kwabo ebusuku futhi kwabenza baphumelela kakhulu ekulweni nezinja.Kodwa-ke, abukho ubufakazi bokuthi babenombono ongcono, noma ukuthi badla ujamu we-bilberry.Enye i-akhawunti ithi amahemuhemu asakazwa ngamasosha ukuze aphazamise amaJalimane ekubeni amaNgisi ayehlola imishini ye-radar ezindizeni zawo.Kungenzeka okuthakazelisayo, kodwa nalokhu akunabufakazi.Kwezinye izinguqulo zendaba, impumelelo yabashayeli bezindiza yayibangelwa ukudla izaqathi.
Nakuba imikhuba yokudla yabashayeli bezindiza beMpi Yezwe Yesibili iphikisana, izinzuzo okuthiwa ama-bilberries zamehlo zavusa isithakazelo sabacwaningi.Lokhu kungenxa yokuthi lamajikijolo anomlando we-folkloric wokwelapha izifo ezisukela ezinkingeni zokujikeleza kwegazi kuya esihudo nasezilonda.Futhi kunezizathu ezithile zezinzuzo ezingase zibe khona, njengoba amajikijolo namajikijolo aluhlaza anothe ngama-anthocyanins, okuwumbala obangela umbala wawo.Ama-anthocyanins anezindawo zokulwa ne-antioxidant futhi ayakwazi ukuqeda ama-radicals amahhala adume kabi akhiqizwa njengomkhiqizo we-metabolism evamile futhi okusolwa ukuthi adlala indima ekuqubuleni izifo ezahlukahlukene.
Amajikijolo namajikijolo anokuqukethwe okufanayo kwe-anthocyanin, nokugcwala okuphezulu kakhulu okutholakala esikhumbeni.Nokho, akukho okukhethekile ngama-bilberry.Amanye ama-cultivar ama-blueberries empeleni anomphumela omkhulu we-antioxidant kune-bilberry, kodwa lokhu akunakubaluleka okusebenzayo.
Amaqembu amabili ocwaningo, elilodwa e-Naval Aerospace Research Laboratory eFlorida kanye nelinye eNyuvesi yase-Tel Aviv banqume ukubona ukuthi ingabe ikhona yini isayensi yangempela ngemuva kwenganekwane yokuthi abashayeli bamabhanoyi baseBrithani bathuthukisa ukucophelela kwabo kokubona nge-bilberry jam.Kuzo zombili izimo, izinsizwa zanikezwa i-placebo, noma izingcaphuno eziqukethe ama-anthocyanins angafika ku-40 mg, inani elingase lisetshenziswe ngokunengqondo kumajikijolo ekudleni.Ukuhlolwa okuhlukahlukene kokulinganisa ukukwazi kokubona ebusuku kwenziwa, futhi kuzo zombili izimo, isiphetho sasiwukuthi akukho ngcono ekuboneni ebusuku okubonakalayo.
Amajikijolo nama-bilberry nawo akhuthazwa njengezithako zokudla ukusiza ukunciphisa ingozi yokuwohloka kwe-macular, isimo esingenakulungiseka esenzeka lapho i-macula, ingxenye emaphakathi ye-retina, iwohloka.I-retina yizicubu ezingemuva kweso ezikwazi ukubona ukukhanya.Ngokombono, ngokusekelwe ekuhlolweni kwaselabhorethri, ama-antioxidants angakwazi ukukhokhela ukuvikelwa.Lapho amangqamuzana e-retina echayeke ku-hydrogen peroxide, i-oxidant enamandla, aba nomonakalo omncane lapho egezwa nge-anthocyanin ekhishwe ngamajikijolo.Lokho, nokho, iminyaka elula kusukela ekuphetheni ngokuthi izithasiselo zokudla ze-anthocyanin zingasiza ekuwohlokeni kwe-macular.Azikho izivivinyo zomtholampilo ezihlole imiphumela yezithako ze-anthocyanin ekuwohlokeni kwe-macular ukuze okwamanje asikho isisekelo sokuncoma okukhishwe kwamajikijolo kunoma iyiphi inkinga yamehlo.
Izinzuzo okuthiwa i-bilberry kanye ne-blueberry extracts azikhawulelwe ekuboneni.Ama-anthocyanins atholakala ezitshalweni nasemifino eminingi, okuphakamisa ukuthi kungenzeka kube ngesinye sezizathu zokuthi kungani ukudla insada yemikhiqizo yezitshalo kunomthelela empilweni enhle.Ngempela, ezinye izifundo ze-epidemiological zibonise ukuthi ukudla okucebile kwe-anthocyanin njengama-blueberries kuhlotshaniswa nengozi encishisiwe yesifo senhliziyo.Nokho, ubudlelwano obunjalo abukwazi ukufakazela ukuthi amajikijolo ayasivikela ngoba abantu abadla amajikijolo amaningi bangase baphile ngendlela ehluke kakhulu kweyabantu abangawadli.
Ukuze kusungulwe ubudlelwano bembangela-nomphumela, ucwaningo lokungenelela luyadingeka, lapho izifundo zidla amajikijolo aluhlaza kanye nomaka abahlukahlukene bezempilo bayagadwa.Ucwaningo olwenziwa abacwaningi baseKing's College eLondon lwenze lokho ngokuphenya imiphumela yokusetshenziswa kwama-blueberry empilweni yemithambo.Iqembu elincane lamavolontiya anempilo lacelwa ukuba liphuze isiphuzo sansuku zonke esenziwe ngamagremu angu-11 empushana yamajikijolo asendle, acishe alingane namagremu ayi-100 amajikijolo asendle amasha.Umfutho wegazi wawuqashwe njalo, njengoba kwakunjalo “nokuncipha kwe-flow-mediated (FMD)” kwemithambo engalweni yalowo mfundi.Lesi isilinganiso sokuthi imithambo ivuleka kalula kanjani njengoba ukugeleza kwegazi kwanda futhi kuyisibonakaliso sengozi yesifo senhliziyo.Ngemva kwenyanga kwaba nokuthuthuka okuphawulekayo ku-FMD kanye nokwehla komfutho wegazi we-systolic.Okuthakazelisayo, kodwa hhayi ubufakazi bokunciphisa kwangempela kwesifo senhliziyo.Ngokufanayo, nakuba imiphumela encishisiwe ngandlela-thile yatholakala lapho ingxube ye-anthocyanins emsulwa, elingana nenani esiphuzweni (160 mg), idliwe.Kubonakala sengathi ama-blueberries anezinye izingxenye ezizuzisayo ngaphandle kwama-anthocyanins.
Ukufaka amajikijolo ekudleni kuyinto enhle ukuyenza, kodwa noma ubani othi okukhishwe kungathuthukisa ukubona ubheka ezingilazini ezinombala orozi.
