Njengoko ibali lihamba, abaqhubi beenqwelo moya baseBritane kwiMfazwe yesibini yeHlabathi batya ijem yebhilberry ukuze baphucule umbono wabo wobusuku.Ewe, libali elimnandi ...
Xa kuziwa ekuvavanyeni izongezo zokutya, umceli mngeni kukufumana ingcaciso ethile xa ujonga inkungu yezifundo eziphikisanayo, uphando olungenamsebenzi, intengiso enenzondelelo egqithisileyo kunye nemithetho karhulumente exengaxengayo.Izicatshulwa zeblueberry kunye nomzala wayo waseYurophu ibhilberry, ngumzekelo.
Iqala ngentsomi echukumisayo.Njengoko ibali lihamba, abaqhubi beenqwelomoya baseBritane basebenzisa iibhilberries ukudubula abalweli baseJamani ngexesha leMfazwe yesibini yeHlabathi.Abazange babakhuphe kwimipu yabo.Bazitya.Ngendlela yejam.Oku kuthiwa kuphucule umbono wabo wasebusuku kwaye kwabenza baphumelela ngakumbi kwii-dogfights.Nangona kunjalo, akukho bungqina bokuba baye baphucula umbono, okanye badla i-bilberry jam.Enye i-akhawunti kukuba i-rumor yasasazwa ngumkhosi ukuphazamisa amaJamani kwinto yokuba amaBritane ayevavanya izixhobo ze-radar kwiinqwelomoya zabo.Inokwenzeka into enomdla, kodwa nayo ayinabungqina.Kwezinye iinguqulelo zebali, impumelelo yabaqhubi beenqwelo-moya yayibangelwa kukutya iminqathe.
Ngelixa imikhwa yokutya yabaqhubi beenqwelomoya beMfazwe yeSibini yeHlabathi iyaxoxwa, iingenelo ekucingelwa ukuba ziibhilberries zamehlo zavusa umdla wabaphandi.Kungenxa yokuba la maqunube anembali ye-folkloric yokunyanga izigulo ukusuka kwiingxaki zokujikeleza kwegazi ukuya kurhudo kunye nezilonda.Kwaye kukho ingqiqo yeenzuzo ezinokwenzeka, kuba iibhilberries kunye neeblueberries zizityebi kwi-anthocyanins, ii-pigments ezinoxanduva lombala wazo.I-Anthocyanins ineepropathi ze-antioxidant kwaye iyakwazi ukuthomalalisa iiradicals zasimahla eziveliswa njengemveliso yemetabolism eqhelekileyo kwaye kurhaneleka ukuba zidlala indima ekubangeleni izifo ezahlukeneyo.
Iibhilberries kunye neeblueberries zinomxholo ofanayo we-anthocyanin, kunye noxinzelelo oluphezulu olufunyenwe eluswini.Nangona kunjalo, akukho nto ikhethekileyo malunga namaqunube.Ezinye iicultivars zeblueberries zinefuthe elikhulu lokulwa ne-antioxidant kune-bilberries, kodwa oku akunantsingiselo ebonakalayo.
Amaqela amabini ophando, elinye kwiNaval Aerospace Research Laboratory eFlorida kunye nelinye kwiYunivesithi yaseTel Aviv bagqiba ekubeni babone ukuba kukho nayiphi na inzululwazi yokwenyani emva kwentsomi yabaqhubi beenqwelomoya baseBritane bonyusa ukutyhutyha kwabo ngejem yebhilberry.Kuzo zombini ezi meko, amadoda amancinci anikwe nokuba i-placebo, okanye izicatshulwa eziqulathe ukuya kuthi ga kwi-40 mg anthocyanins, isixa esinokuthi sisetyenziswe ngokufanelekileyo kumaqunube ekutyeni.Iimvavanyo ezahlukeneyo zokulinganisa ubusuku obubonakalayo bulawulwa, kwaye kuzo zombini iimeko, isiphelo kukuba akukho phuculo kumbono wasebusuku.
I-Blueberry kunye ne-bilberry extracts nazo zikhuthazwa njengezongezo zokutya ukuze zincede ukunciphisa umngcipheko wokutshatyalaliswa kwe-macular, imeko engenakulungiseka eyenzekayo xa i-macula, inxalenye ephakathi ye-retina, iyancipha.Iretina sisihlunu esingasemva kwiliso esibona ukukhanya.Ngokwethiyori, ngokusekwe kwiimvavanyo zaselabhoratri, i-antioxidants inokuhlawula ukhuseleko.Xa iiseli zeretina zisesichengeni sehydrogen peroxide, ioksijini eyomeleleyo, ziye zonakaliswe kancinane xa zihlanjwa kwisicatshulwa seblueberry anthocyanin.Oko, nangona kunjalo, yiminyaka elula ukusuka ekugqibeni ukuba izongezo zokutya ze-anthocyanin zinokunceda ngokuncipha kwe-macular.Akukho lulingo lwezonyango luye lwavavanya iziphumo zezongezelelo ze-anthocyanin kwi-macular degeneration ukuze okwangoku kungabikho siseko sokucebisa amaqunube equnube kuyo nayiphi na ingxaki yamehlo.
Iinzuzo ezicingelwayo ze-bilberry kunye ne-blueberry extracts azikhawulelwanga kumbono.I-Anthocyanins ifumaneka kwiziqhamo ezininzi kunye nemifuno, ephakamisa amathuba okuba ibe sesinye sezizathu zokuba ukutya okuninzi kwemveliso yezityalo kunegalelo kwimpilo entle.Ewe, ezinye izifundo ze-epidemiological zibonise ukuba ukutya okutyebileyo kwe-anthocyanin okufana neblueberries kunxulunyaniswa nomngcipheko oncitshisiweyo wesifo sentliziyo.Noko ke, unxulumano olunjalo alunakungqina ukuba la maqunube ayakhusela ekubeni abantu abatya amaqunube amaninzi banokuphila ngendlela eyahlukileyo kweyabantu abangawatyiyo.
Ukuze kusekwe ubudlelwane besizathu-kunye-nesiphumo, isifundo songenelelo siyafuneka, apho izifundo zidla ama-blueberries kunye namanqaku ahlukeneyo empilo abekwe esweni.Uphononongo olwenziwe ngabaphandi kwiKholeji yaseKing eLondon lwenze oko ngokuphanda iziphumo zokusetyenziswa kwamaqunube kwimpilo yemithambo.Iqela elincinane lamavolontiya asempilweni lacelwa ukuba litye isiselo semihla ngemihla esenziwe nge-11 grams ye-wild blueberry powder, ephantse ilingane ne-100 grams yamaqunube asendle amatsha.Uxinzelelo lwegazi lwalujongwa rhoqo, njengoko kwakunjalo "i-flow-mediated dilation (FMD)" yemithambo ekwingalo yomfundi.Lo ngumlinganiselo wendlela enwenwa ngayo imithambo yegazi njengoko ukuhamba kwegazi kusanda kwaye kuxela kwangaphambili ingozi yesifo sentliziyo.Emva kwenyanga kukho ukuphucuka okukhulu kwi-FMD kunye nokuhla kwe-systolic blood pressure.Unomdla, kodwa kungekhona ubungqina bokwehliswa kwangempela kwisifo senhliziyo.Ngokufanayo, nangona iziphumo ezincitshisiweyo zifunyenwe xa umxube we-anthocyanins ecocekileyo, elingana nesixa kwisiselo (160 mg), idliwe.Kubonakala ngathi iiblueberries zinamanye amacandelo aluncedo ngaphandle kwe-anthocyanins ngokunjalo.
Ukubandakanya i-blueberries ekutyeni yinto efanelekileyo yokwenza, kodwa nabani na othi izicatshulwa zinokuphucula umbono ujonge kwiiglasi ezinemibala ebomvu.
