Ama-blueberry asephenduke into eyinhloko ezinqolobaneni zokuthenga futhi abe yisihloko esivame ukuxoxwa ngaso ezinkundleni zokuxhumana, lapho ngezinye izikhathi kuthiwa anemiphumela ecishe ibe yisimangaliso. Iqiniso lesayensi liyinkimbinkimbi kakhulu : kukhona ucwaningo oluthembisayo, kodwa futhi nosayizi omncane wamasampula, imiphumela yokuqala, kanye nezixwayiso mayelana nendlela yokuhumusha idatha.
Emasontweni amuva nje, kuvele izindaba eziningana mayelana nalesi sithelo. Ngakolunye uhlangothi, izivivinyo ezintsha ngokusebenza kahle kwezemidlalo kanye nempilo ye-cardiometabolic ; ngakolunye uhlangothi, isibuyekezo esinxusa ukuqaphela ngama-blueberries abilisiwe; futhi ngaphezu kwalokho, ukukhunjulwa kwama-blueberries aqandisiwe e-United States ngenxa yokuqubuka kwe-E. coli. Konke lokhu kudweba isithombe lapho kubalulekile khona ukuhlukanisa phakathi kwalokho okuqinisekisiwe nalokho okusazwakala njengesithembiso.
Ukusebenza kwezemidlalo: izibalo eziheha amehlo, kodwa ezibhalwe kahle
Ucwaningo ludonsele ukunaka ngemiphumela yalo: abagijimi abathathe isithasiselo se-blueberry isonto lonke baqede ukuhlolwa kwamakhilomitha angu-22,2 ngokushesha okungu-4,2% kunalabo abadle i-placebo. Umehluko ojwayelekile udlule imizuzu eyisikhombisa, ngesikhathi esingu-2:37:05 uma kuqhathaniswa no-2:44:30.
Nokho, lolu cwaningo lwaluluncane kakhulu: abagijimi bezintaba abayisishiyagalolunye kuphela , futhi lwaluxhaswe yi-American Blueberry Council. Abahlanganyeli baqede izivivinyo ezimbili zesikhathi ezihlukene ngezinsuku ezingu-21, futhi ngaphambi kokuhlolwa ngakunye, bachitha isonto lonke bedla i-blueberry powder noma i-placebo. Umthamo wawulingana nezinkomishi ezintathu ze-blueberry entsha ngosuku.
Abalobi baqaphele izinga lokushaya kwenhliziyo eliphansi lokuphumula kanye nokukhathala okuncane, yize kungezona zonke iziguquguquko ezihlaziyiwe ezibonise umehluko obalulekile. Basikisela ukuthi incazelo isezinhlakeni ezitholakala kuma-blueberries, ezihlolwa ngamandla azo okunciphisa ukucindezeleka kwe-oxidative kanye nokuvuvukala okuvela ekuzivocavoceni isikhathi eside kanye nokukhuthaza ukukhiqizwa kwe-nitric oxide kanye nokugeleza kwegazi kwemisipha. Njengoba kunabahlanganyeli abayisishiyagalolunye kuphela, ukukhuluma 'ngokusebenzisa i-blueberry doping' kungaba ukweqisa.
Ubuchopho nenhliziyo: yini efundiwe nokuthi yini esavulekele ukuxoxwa ngayo
Udokotela wezifo zenhliziyo u-Aurelio Rojas uphikise ngokuthi lesi sithelo sivelele ngamandla aso okuvikela ubuchopho nenhliziyo . Ngokusho kwencazelo yakhe, sandisa ukugeleza kwegazi ebuchosheni ezindaweni ezixhumene nenkumbulo nokunaka, njenge-prefrontal cortex kanye ne-hippocampus, futhi wacaphuna ucwaningo olwanyatheliswa kuyi-Nutritional Neuroscience olubonisa ukuthuthuka okulinganiselwe ngemva kwamasonto ayi-12.
Uphinde wakhuluma ngocwaningo lwaseHarvard lwabesifazane abangaphezu kuka-16.000 lapho ukusetshenziswa njalo kwakuhlotshaniswa nokukhunjulwa okuthuthukisiwe kanye nempilo yobuchopho, okubambezela ukwehla kwengqondo kuze kube yiminyaka emibili nengxenye. Ngokuphathelene nomfutho wegazi, uthe izivivinyo eziningana ezilawulwayo zibone ukwehla kwamamilimitha angu-4 kuya kwangu-6 e-mercury kumfutho wegazi we-systolic, okuyisibalo asibheka njengesibalulekile engozini yenhliziyo nemithambo yegazi.
Kodwa-ke, ubufakazi abufani. Ukubuyekezwa kwezilingo zemitholampilo ezingu-12 ezenziwa eminyakeni engaphezu kwengu-24 emazweni amane ngama-blueberry asendle kuthole imiphumela emihle kwezinye izinkomba ze-cardiometabolic, njengomfutho wegazi, amafutha egazini, kanye ne-glucose, kodwa abalobi bagcizelele ukuthi le miphumela ayiqinisekisi. Bafuna ucwaningo olwengeziwe ukuze baqonde ukuthi kungani izimpendulo ziyahlukahluka kuye ngokuthi umuntu ngamunye udlani, inani elidliwayo, noma uhlobo ama-blueberry adliwa ngalo.
Imvelo, iqandisiwe futhi ibilisiwe: umehluko ofanele ukuqondwa
Izinhlobo zasendle zivame ukuba zincane kunezo ezitshaliwe. Lesi sici sisho ukuthi zinesikhumba esiningi ngokulingana , futhi ngobuningi, i-fiber kanye ne-anthocyanins eningi, imibala ezinika umbala wazo oluhlaza okwesibhakabhaka. I-fiber encibilikayo ingakha into ejiyile ngesikhathi sokugaya futhi isebenze njengokudla kwamagciwane amathumbu. Iqiniso lokuthi izinhlobo zasendle zinezinga eliphezulu lezingxenye ezithile akusho ukuthi izinhlobo ezitshaliwe azinawo umsoco.
Ama-blueberry aqandisiwe ngokuyinhloko ayisinqumo esiwusizo: aqandisiwe lapho esevuthiwe kahle, okusiza ukugcina i-fiber, ama-anthocyanins, nama-antioxidants isikhathi eside futhi kunciphisa ingozi yokonakala ngaphambi kokusetshenziswa. Akukho bufakazi bokuthi anikeza noma iyiphi inzuzo yezokwelapha ngaphezu kwama-blueberry amasha ngokwawo.
Icala lama-blueberry abilisiwe lihlukile. Nakuba evame ukunconywa ezinkundleni zokuxhumana njengathuthukisa ngqo impilo yamathumbu, kusenobufakazi obanele bokusekela lesi simangalo kubantu . Ukubuyekezwa kukhuluma ngezifundo zokuqala zezilwane mayelana nokugaya i-glucose kanye nama-carbohydrate, kodwa lokhu akuvumeli ukuthi kufinyelelwe esiphethweni sokuthi okufanayo kuzokwenzeka kubantu noma ukuthi kuphakeme kunama-blueberry avamile. Ukubiliswa nakho akubonakali kuyisidingo semiphumela engaba khona yama-blueberry asendle.
Isexwayiso sokuphepha: ama-blueberry aqandisiwe abikwe e-United States
Kanye nezifundo zokudla okunempilo, isexwayiso sezempilo sisebenze njengesikhumbuzo sokuthi ukuphepha kokudla akuxhomekile ezimpahleni zesithelo. Umndeni waseFlorida umangalele i-Publix kanye nomsabalalisi we-Quirch Foods, usola ukuthi owesifazane ushonile kanti indodana yakhe yalaliswa esibhedlela ngemuva kokudla ama-blueberries aqandisiwe e-GreenWise Organic. Icala lithi umkhiqizo wawunephutha futhi ungcolile, yize lezi zinsolo zingabonisi isinqumo senkantolo noma isinqumo esisemthethweni.
Iziphathimandla zikahulumeni ziqinisekisile ukuthi ama-blueberries aqandisiwe akhiqizwa yi-Frutas y Hortalizas del Sur SA yaseChile ahlobene nokuqubuka kwe-E. coli O145 emazweni amaningi. I-CDC ibike amacala ayi-17 ezifundazweni ezimbili, ukulaliswa esibhedlela okuyisithupha, futhi akukho ukufa okubikwe ngokusemthethweni ekubuyekezweni kwayo kokugcina ngoSepthemba 21. Ukugula kwaqala phakathi kukaMeyi 11 no-Agasti 2.
Ekuqaleni iPublix yakhumbula inani elilodwa ngoJulayi 3 yabe isikhulisa inani lokukhunjulwa kwama-blueberries aqandisiwe kuwo wonke ama-GreenWise Organic Whole Blueberries nama-Whole Mixed Berries kumaphakheji angu-10 nama-ounces angu-48 asatshalaliswa eFlorida, e-Alabama, eGeorgia, eKentucky, eNorth Carolina, eSouth Carolina, eTennessee naseVirginia. Lokhu kubuyiselwa kwemali kwahlukaniswa njengesenzo seKlasi I ngenxa yengozi yempilo engaba khona. Kamuva, ukubuyiselwa kwemali kwanwetshwa kwabaningi ama-Great Value Organic Triple Berry Blend athengiswa eWalmart emazweni angu-26 nasePuerto Rico.
Ngakho-ke isithombe sama-blueberry asifani nhlobo nomnyama nomhlophe. Kunezimpawu ezithakazelisayo mayelana nokusebenza kahle, inkumbulo, kanye nempilo yenhliziyo, kodwa eziningi zivela ezifundweni ezincane ezixhaswe yimboni noma ngemiphumela abacwaningi ngokwabo abayibheka njengeyokuqala. Izinhlobo zasendle nama-blueberry aqandisiwe anezinzuzo ezithile maqondana nokwakheka nokulondolozwa, kuyilapho ama-blueberry abilisiwe esadinga ukuhlolwa kwabantu. Futhi, njengoba ukukhunjulwa kwe-US kubonisa, azikho izithelo, noma zingabonakala ziphilile kangakanani, ezingenabungozi uma uchungechunge lokuphepha kokudla luhluleka.
