Sezvo nyaya ichienda, vatyairi veBritish muHondo Yenyika Yechipiri vakadya jamu yebhiribheri kuti vavandudze chiono chavo chehusiku.Zvakanaka, inyaya yakanaka ...
Kana zvasvika pakuongorora zvekudya zvinowedzera, dambudziko nderekutsvaga kujeka kana uchitarisa kuburikidza nemhute yezvidzidzo zvinopokana, tsvakiridzo isina musoro, kushambadza kwakanyanyisa uye mirairo yehurumende yakasununguka.Zvikamu zveblueberry uye cousin yayo yekuEurope iyo bilberry, ndiyo muenzaniso.
Kunotanga nengano inogombedzera.Sezvo nyaya ichienda, vatyairi veBritish vakashandisa mabhiribheri kupfura pasi varwi veGerman munguva yeHondo Yenyika Yechipiri.Havana kuvaridzira pfuti dzavo.Vakazvidya.Muchimiro chejamu.Izvi zvinonzi zvakavandudza maonero avo ehusiku uye zvakaita kuti vabudirire mukurwa kwembwa.Nekudaro, hapana humbowo hwekuti vaive vavandudza kuona, kana kuti vakadya jamu yebhiribheri.Imwe nhoroondo ndeyekuti runyerekupe rwakaparidzwa nemauto kuvhiringidza maGerman kubva pakuti maBritish aiedza michina yeradar mundege dzavo.Mukana unonakidza, asi izvi zvakare hazvina humbowo.Mune dzimwe shanduro dzenyaya, kubudirira kwevatyairi vendege kwaikonzerwa nekudya makarotsi.
Kunyange tsika dzekudya dzevatyairi veHondo Yenyika Yechipiri dzichikakavadzana, izvo zvinofungidzirwa mabhenefiti emabilberries emeso akamutsa kufarira kwevaongorori.Imhaka yekuti ma berries aya ane folkloric nhoroondo yekurapa zvirwere kubva kumatambudziko ekutenderera kusvika kumanyoka nemaronda.Uye pane zvimwe zvikonzero zvezvibatsiro zvinogoneka, sezvo mabhiribheri nemablueberries akapfuma mu anthocyanins, ma pigment anokonzera ruvara rwawo.Anthocyanins ine antioxidant zvimiro uye inokwanisa kudzikamisa iyo ine mukurumbira wakashata radicals iyo inogadzirwa seyakagadzirwa neyakajairwa metabolism uye inofungidzirwa kuita basa mukumutsa zvirwere zvakasiyana.
Mabhiribheri nemablueberries ane zvakafanana anthocyanin content, ine yakanyanya kuwanda inowanikwa paganda.Zvisinei, hapana chakakosha pamusoro pebilberries.Mamwe macultivars eblueberries ane akanyanya antioxidant mhedzisiro pane mabhiribheri, asi izvi hazvina zvazvinoreva.
Mapoka maviri ekutsvagisa, rimwe kuNaval Aerospace Research Laboratory muFlorida uye rimwe kuTel Aviv University rakasarudza kuona kana pakanga paine sainzi chaiyo iri seri kwengano yevatyairi vendege vekuBritain vachiwedzera kusanzwisisa kwavo nejamu rebhiribheri.Muzviitiko zvese izvi, varume vechidiki vakapihwa ingave placebo, kana zvinyorwa zvine anthocyanins anosvika 40 mg, chiyero chinogona kudyiwa zvine mutsindo kubva kumabheri mukudya.Miedzo yakasiyana-siyana yekuyera husiku hwekuona acuity yakaitwa, uye muzviitiko zvese izvi, mhedziso yaive yekuti hapana kuvandudzwa kwekuona kwehusiku kwakaonekwa.
