I-Blueberry Extract iyisengezo sempilo semvelo esenziwe ngejusi le-blueberry eligxilile. I-Blueberry Extract iwumthombo ocebile wezakhamzimba nama-antioxidants aqukethe izakhi zezitshalo eziwusizo (kufaka phakathi i-flavonol quercetin) nama-anthocyanins, okucatshangwa ukuthi anciphisa ukuvuvukala futhi avimbele izifo zenhliziyo nomdlavuza.
Kwezokwelapha zemvelo, i-blueberry extract kukholakala ukuthi inezinzuzo eziningi zezempilo, okuhlanganisa nempilo engcono yemithambo yegazi. Ivame ukusetshenziselwa ukwelapha noma ukuvimbela lezi zimo ezilandelayo:
Nakuba ucwaningo ngemiphumela yezempilo ye-blueberry extract lulinganiselwe, ezinye izifundo ziphakamisa ukuthi ama-blueberry angaba nezinzuzo ezithile ezingaba khona.
Izifundo ngama-blueberry kanye nolwazi zisebenzise ama-blueberry amasha, i-blueberry powder, noma i-blueberry juice concentrate.
Ocwaningweni olwanyatheliswa kuyi-Food & Function ngo-2017, abacwaningi bahlole imiphumela yokuqonda yokusebenzisa i-blueberry powder eyomisiwe efriziwe noma i-placebo eqenjini lezingane eziphakathi kweminyaka engu-7 nengu-10. Ngemva kwamahora amathathu besebenzisa i-blueberry powder, abahlanganyeli banikezwa umsebenzi wokuqonda. Ocwaningweni olwanyatheliswa kuyi-Food & Function ngo-2017, abacwaningi bahlole imiphumela yokuqonda yokusebenzisa i-blueberry powder eyomisiwe efriziwe noma i-placebo eqenjini lezingane eziphakathi kweminyaka engu-7 nengu-10. Ngemva kwamahora amathathu besebenzisa i-blueberry powder, abahlanganyeli banikezwa umsebenzi wokuqonda. Ocwaningweni olwanyatheliswa kuyi-Food & Function ngo-2017, abacwaningi bahlole imiphumela yokucabanga yokudla i-blueberry powder eyomisiwe ngokuqandisa noma i-placebo eqenjini lezingane ezineminyaka engu-7 kuya kwengu-10.Ngemva kwamahora amathathu bedle impuphu yama-blueberry, abahlanganyeli banikezwa umsebenzi wokuqonda. Esifundweni sango-2017 esanyatheliswa kuyi-Food & Function, abacwaningi bahlole imiphumela yokuqonda yokudla i-blueberry powder eyomisiwe ngokuqandisa noma i-placebo eqenjini lezingane ezineminyaka engu-7 kuya kwengu-10.Ngemva kwamahora amathathu bedle i-blueberry powder, abahlanganyeli banikezwa umsebenzi wokuqonda. Abahlanganyeli abathathe i-blueberry powder batholakale beqeda umsebenzi ngokushesha okukhulu kunalabo abaseqenjini lokulawula.
Ama-blueberry omisiwe ngokuqandisa angathuthukisa nezici ezithile zokusebenza kwengqondo kubantu abadala. Isibonelo, ocwaningweni olwanyatheliswa kuyi-European Journal of Nutrition, abantu abaneminyaka engu-60 kuya kwengu-75 badla ama-blueberry omisiwe ngokuqandisa noma i-placebo izinsuku ezingu-90. Abahlanganyeli baqede ukuhlolwa kwengqondo, ibhalansi kanye nokuhamba ekuqaleni futhi baphinde babonakala ezinsukwini ezingu-45 no-90.
Labo abathathe ama-blueberry benze kangcono ekuhlolweni kwengqondo, okuhlanganisa ukushintsha imisebenzi nokufunda ulimi. Kodwa-ke, ukuhamba noma ibhalansi akuzange kuthuthuke.
Ukuphuza iziphuzo ze-blueberry kungathuthukisa inhlalakahle yomuntu siqu. Ucwaningo olwanyatheliswa ngo-2017 luhilele izingane kanye nabantu abadala abasebasha abaphuza isiphuzo se-blueberry noma i-placebo. Isimo sengqondo sabahlanganyeli sahlolwa emahoreni amabili ngaphambi nangemva kokuphuza isiphuzo.
Abacwaningi bathole ukuthi isiphuzo sama-blueberry sandisa imiphumela emihle kodwa asinawo umthelela omkhulu emizweni emibi.
Embikweni ka-2018 owashicilelwa ku-Review of Food Science and Nutrition, abacwaningi babuyekeze izivivinyo zemitholampilo ezishicilelwe ngaphambilini zama-blueberries noma ama-cranberry zokulawula ushukela egazini kusifo sikashukela sohlobo 2.
Ekubuyekezweni kwabo, bathole ukuthi ukusebenzisa i-blueberry extract noma izithasiselo eziphuzwayo (ezihlinzeka ngama-milligram angu-9.1 noma angu-9.8 (mg) e-anthocyanins, ngokulandelana) amasonto angu-8 kuya kwangu-12 kwakuwusizo ekulawuleni amazinga kashukela egazini kubantu abanesifo sikashukela sohlobo 2.
Kwezokwelapha zemvelo, i-blueberry extract inezinzuzo zezempilo, okuhlanganisa ukuthuthukisa impilo yemithambo yegazi nokusiza ukwehlisa umfutho wegazi kubantu abanomfutho wegazi ophezulu.
Olunye ucwaningo luthole ukuthi ukudla ama-blueberry nsuku zonke amasonto ayisithupha akuzange kuthuthukise umfutho wegazi. Kodwa-ke, kwathuthukisa ukusebenza kwe-endothelium. (Ungqimba olungaphakathi lwe-arterioles, i-endothelium, luhilelekile emisebenzini eminingi ebalulekile yomzimba, okuhlanganisa nokulawulwa komfutho wegazi.)
Kuze kube manje, kuncane okwaziwayo ngokuphepha kokwengezwa kwe-blueberry extract yesikhathi eside. Kodwa-ke, akwaziwa ukuthi kuphephile kangakanani ukuphuza i-blueberry extract.
Ngenxa yokuthi i-blueberry extract inganciphisa amazinga kashukela egazini, abantu abathatha imithi yesifo sikashukela kufanele basebenzise lesi sithasiselo ngokuqapha.
Noma ubani oke wahlinzwa kufanele ayeke ukuthatha i-blueberry extract okungenani amasonto amabili ngaphambi kokuhlinzwa okuhleliwe ngoba i-hypoglycemia ingase ivele.
I-Blueberry extract itholakala kuma-capsule, ama-tincture, ama-powder, kanye nama-extract ancibilikayo emanzini. Itholakala ezitolo zokudla zemvelo, emakhemisi, naku-inthanethi.
Akukho silinganiso esijwayelekile se-blueberry extract. Kudingeka ucwaningo olwengeziwe ngaphambi kokuba kutholakale uhlobo oluphephile.
Landela iziqondiso ezikulebula lesengezo, ngokuvamile isipuni esisodwa sempuphu eyomile, ithebhulethi eli-1 (eliqukethe u-200 kuya ku-400 mg we-blueberry concentrate), noma izipuni eziyi-8 kuya kweziyi-10 ze-blueberry concentrate.
I-extract ye-blueberry itholakala kuma-blueberry amade atshaliwe noma ama-blueberry amancane asendle. Khetha izinhlobo ze-organic ezitholakala ukuthi ucwaningo lubonisa ukuthi ziphezulu kuma-antioxidants kanye nezinye izakhamzimba kunezithelo ezingezona eze-organic.
Sicela uqaphele ukuthi i-blueberry extract ihlukile kwi-blueberry leaf extract. I-Bilberry extract itholakala esithelweni se-blueberry, kanti i-leaf extract itholakala emaqabunga esihlahla se-blueberry. Zinezinzuzo ezithile ezihambisanayo, kodwa azikwazi ukushintshaniswa.
Amalebula ezithasiselo kufanele asho ukuthi ngabe okukhishwe kuvela ezithelweni noma emaqabungeni, ngakho qiniseka ukuthi uhlola ukuze ukwazi ukuthenga umkhiqizo owufunayo. Qiniseka futhi ukuthi ufunda lonke uhlu lwezithako. Abakhiqizi abaningi banezela amanye amavithamini, izakhamzimba, noma izithako zezitshalo kulokho okukhishwe kuma-blueberry.
Ezinye izithako, njengevithamini C (i-ascorbic acid), zingathuthukisa imiphumela ye-blueberry extract, kanti ezinye zingase zihlangane nomuthi noma zibangele ukusabela okungekuhle. Ikakhulukazi, izithako ze-marigold zingabangela ukusabela kokungezwani komzimba kubantu abazwela i-ragweed noma ezinye izimbali.
Futhi, hlola ilebula ukuze uthole uphawu oluthembekile lomuntu wesithathu, njenge-USP, i-NSF International, noma i-ConsumerLab. Lokhu akuqinisekisi ukusebenza kahle komkhiqizo, kodwa kufakazela ukuthi izithako ezibhalwe kulebula yilokho okutholayo ngempela.
Kungcono yini ukuthatha i-blueberry extract kunokudla ama-blueberry aphelele? Ama-blueberry aphelele kanye nama-blueberry extracts ayimithombo ecebile yamavithamini namaminerali. Kuye ngefomula, izithasiselo ze-blueberry extract zingase zibe nezilinganiso eziphezulu zezakhamzimba kunezithelo eziphelele.
Kodwa-ke, imicu iyasuswa ngesikhathi senqubo yokukhipha. Ama-blueberry abhekwa njengomthombo omuhle we-fiber, ngamagremu angu-3.6 ngendebe eyodwa. Ngokusekelwe ekudleni kwama-calories angu-2,000 ngosuku, lokhu kungamaphesenti angu-14 okudla kwakho kwe-fiber okunconywayo kwansuku zonke. Uma ukudla kwakho kakade kuntula i-fiber, ama-blueberry aphelele angase abe ngcono kuwe.
Yikuphi okunye ukudla noma izithasiselo eziqukethe ama-anthocyanins? Ezinye izithelo nemifino ecebile ngama-anthocyanins zifaka ama-blackberry, ama-cherry, ama-raspberry, amapomegranate, amagilebhisi, u-anyanisi obomvu, ama-radish, nobhontshisi. Izithasiselo eziningi ze-anthocyanin zifaka ama-blueberries, i-acai, i-aronia, ama-marmalade cherry, nama-elderberry.
Nakuba kusenesikhathi kakhulu ukuphetha ngokuthi i-blueberry extract ingavimbela noma yelaphe noma yisiphi isifo, ucwaningo lubonisa ngokusobala ukuthi ama-blueberry aphelele angumthombo onamandla wezakhamzimba, okuhlanganisa amavithamini, amaminerali, kanye nama-antioxidants abalulekile. Uma ucabanga ukuthatha izithasiselo ze-blueberry extract, khuluma nomhlinzeki wakho wezempilo ukuze uthole ukuthi ikulungele yini.
