Inani leMetabolic of Acetic Acid
Uviniga usetshenziswe imithi izinkulungwane zeminyaka. Isithako esisebenzayo sasicatshangelwa kakhulu ukuthi uHippocrates (cishe ngo-420 BC) wasebenzisa uviniga ukuze aphulukise amanxeba. Isazi sezempi, uHannibal waseCarthage (c. 200 BC) amatshe ahlakazekile, noCleopatra (c. 50 BC) amaparele aqhekekile ukudala i-potion ngothando ngeviniga. Iviniga ibonakala iyindlela yokwelapha-konke cishe cishe konke okuvela ekuguleni ukuthuthukisa imizwa engokomzwelo.
UVinegar uyaqhubeka nokuhlinzeka ngezinzuzo eziningi zezempilo ngokusho kocwaningo olungapheli. Izifundo ezizimele zibonisa ukuthi kungasiza ukuphatha amazinga kashukela egazi ngisho nokucindezela amafutha omzimba. Iwayini elivuthiwe kuthiwa likhuthaza ukushisa okunezinga eliphumelelayo njengengxenye yohlelo lokulahlekelwa isisindo.
Ingabe kukhona ubufakazi obanele bokufakazela uviniga kunciphisa amafutha omzimba? Isebenza kanjani emzimbeni ukufeza le nqubo?
Uviniga ne-Acetic Acid
Uviniga uqukethe i-acetic acid eyenziwa ngokuvutshelwa noma yikuphi umthombo we-carbohydrate kusuka kuzinhlamvu kuya kuma-apula. I-Acetic acid inikeza uviniga ukunambitheka okomuncu futhi iyisithako esisebenzayo esihlanganiswe nezinzuzo eziningi zezempilo. Iviniga elisetshenziselwa ukusetshenziswa cishe ngamaphesenti amathathu kuya kwengu-9 ngevolumu futhi ngempela nje i-diluted acetic acid.
I-acetic acid iyinhlangano yamafutha e-short chain-chain, eyenzeka ngokwemvelo emzimbeni wamanzi, futhi ikhiqizwa amabhaktheriya amahle emathunjini akho . Uma udla ukudla okune-fiber, igciwane lakho liqinisa fiber ekolon yakho futhi likhiqize i-acetic acid. Ukwandisa inani lamakhemikhali ama-acidi e-short chain efana ne-acetic acid kuthiwa lidlala indima ebalulekile ekunciphiseni kwamafutha omzimba. Kungasiza futhi ngemisebenzi yomzimba elandelayo:
- Ukwandisa imetabolism
- Thuthukisa indlela umzimba odla ngayo ama-carbohydrate namafutha.
- Thuthukisa impilo ye-colon
- Ukucindezela ngokwemvelo ukucindezela
Isifundo sezilwane esashicilelwe kuyi- Journal of Agricultural and Food Chemistry sathola uviniga ukuvimbela ukuqoqwa kwamafutha omzimba. Abacwaningi baphetha iviniga babe nomphumela ofanayo kubantu. Lezi zithole zenza ucwaningo olwengeziwe luhlolisise uma uviniga ungasiza abantu ukuba banciphise amafutha omzimba.
Uviniga Usiza Ukushisa Nokunciphisa Amafutha Emzimbeni
Ucwaningo luqhutshwa eJapane ngezihloko eziyi-155 ezikhudlwana kanye nesikhathi sokulashwa kwamasonto angu-12. Abahlanganyeli babehlukaniswe ngamaqembu amathathu ngokususelwa kwesisindo esifanayo, i-BMI (Body Mass Index), nokulinganisa isisindo.
Phakathi nesilingo sokuhlolwa, amavolontiya aphuza isiphuzo esingu 500ml esinezivinyo zokuviniga ze 750mg, 1500mg noma 0mg placebo. I-Apple cider uviniga (i-ACV) ikhethiwe ngenxa yokuthi iyathandeka kakhulu. Ukudla nokuzivocavoca kwakulindelwe ngokucophelela futhi kuqoshiwe ngokunembile ngesikhathi sesifundo.
Abahlanganyeli ukuphuza iviniga ephansi nephezulu kakhulu baqala ukukhombisa imiphumela emihle. Phakathi nesonto lesine, izihloko zokuhlolwa zinciphile ngesisindo, amaphesenti amafutha omzimba, kanye ne-BMI uma kuqhathaniswa neqembu le-placebo. Izilinganiso zezintambo zanciphisa nesonto lokuqala futhi zaqhubeka phakathi nesikhathi sokufunda.
Labo abaphuza iviniga eviniga kakhulu kakhulu babonisa ukuthuthukiswa okukhulu. Kubonakala sengathi ukuphuza ngaphezulu kungaba ngcono. Okutholakele kubonisa ukuthi ama-acetic acid amanani aphakeme kakhulu afaneleka ekutheni amafutha ashisa ngokuphumelelayo nokucindezela izitolo ze-fat.
I-acetic acid ibonakala ibasiza umzimba ukucindezela amafutha omzimba ngenqubo ebizwa ngokuthi ukuvinjelwa kwe-lipogenesis (isitoreji samafutha). Lokhu kusho ukuthi uviniga (i-acetic acid) ivimba ikhono lamanye ama-enzyme ekwenzeni ama-acids amafutha emzimbeni. Ngokusobala, uma udla uviniga, usebenza njengomlamuleli wokulawula izinqubo zamakhemikhali ezingahle zidale amafutha.
Ucwaningo lubonisa ukuthi uviniga uvuselela amafutha e-fat oxidation (ukushisa). Lokhu kwenzeka njengempendulo ekuthuthukiseni ama-bacteria okuthonya ukuthi umzimba wakho uvutha kanjani futhi ugcina amafutha. Ngokusho kocwaningo, i-acetic acid ilawula umzimba we-fat metabolism ngokwandisa izinga lomzimba wakho oshisa amafutha ngenkathi kunciphisa ukugcinwa kwamafutha.
Iziphetho zithembele kuviniga njengengcindezi enamandla nokushisa. Ubani odingayo amafutha anezindleko ezibizayo, ezingenakusiza uma isisombululo esihle futhi esiphephile cishe ku-pantry yakho? Iviniga nayo yaboniswa ukuhlinzeka ngezinzuzo eziningi zezempilo.
Uviniga Uyanciphisa I-Belly Fat
Ngaphezu kokusiza ekulahlekelweni kwamafutha, ezinye izinzuzo zezempilo zatholakala ngesikhathi sokutadisha. Kwakukhona ukwehla okuphawulekayo emahlathini e-visceral abahlanganyeli abaphuza kokubili amazinga aphansi aviniga.
Amagciwane angama-visceral atholakala emgodini wesisu futhi azungeze izitho ezibalulekile njenge-pancreas, isibindi namathumbu akho. Kubizwa nangokuthi 'amafutha asebenzayo' adlala indima ezinkambisweni zakho zokuxilonga kanye nehomoni.
Ukutholakala kocwaningo kubonisa ukuthi kuncishiswe amafutha a-visceral kunomthelela omuhle ezinhlobonhlobo zobungozi obunjenge-hypertension nokukhubazeka kwe-glucose ukubekezelelana. Okunye okuphawula ukuthi kunciphise amazinga e-triglyceride (amafutha egazini) ekunciphiseni ingozi yesifo senhliziyo.
Kubonakala sengathi uviniga uzuzisa isisindo esinciphile, kunciphise amafutha we-visceral ne-subcutaneous, futhi kunciphisa amazinga we-triglyceride ngaphandle kwemiphumela emibi.
Uviniga Uthuthukisa I-Glucose Impendulo
Ucwaningo oluncane olwanyatheliswa kuyi- European Journal of Clinical Nutrition luhlolisise ukuthi uviniga ungathinta kanjani i-blood glucose (ushukela) ngesikhathi sokudla okuxubile kubantu abadala abanempilo. Abantu abadala abahlanu abanempilo babekhethiwe ngokukhethiwe futhi banikwa ukudla okuyisithupha.
Ukudla kwakune-ulethisi ngamafutha omnqumo kuphela, amafutha omnqumo ne-1g acetic acid uviniga, noma uviniga ongenayo i-sodium bicarbonate, isithako esisebenzayo ekwakheni i-soda . Ngezikhathi ezintathu, ukudla kokuhlolwa kwalandelwa nge-50g wezinkwa ezimhlophe ze-carbohydrate.
Ama-sampuli wegazi athathwa ngaphambi nangaphezulu kufika kumaminithi angu-95 ngemuva kokudla ukudla. Abahlanganyeli abadla i-ulethisi ngeviniga kuphela futhi balandelwa isinkwa esimhlophe babonisa ukuthi amaphesenti angu-31 anciphisa ukuphendula kwe-glucose uma kuqhathaniswa neqembu le-placebo.
Imiphumela ibonisa ukuthi ukudla okuxubile okuqukethe i-acetic acid ngendlela yamaviniga kunciphisa impendulo ye-glycemic egazini. Kubonakala iviniga akuyona nje kuphela isaladi esiphundu, kodwa futhi ikusiza ukuba ugcine amazinga ashukela egazini.
I- Annals of Nutrition and Metabolism yashicilela isifundo esifanayo. Ucwaningo lwaluqondene ngqo noviniga ukungenisa ngesikhathi sokudla kodwa futhi namahora amahlanu ngaphambili. Abacwaningi babefuna noma yikuphi ukungezwani kwempendulo ye-glycemic (ushukela) esekelwe lapho iviniga idliwe.
Ukuhlelwa kwesikhathi okwemvelo kuye kwaba yinto ephawulekayo engxoxweni yesayensi nocwaningo. Ucwaningo olunezinombolo ezine olunikezela isilingo esisodwa kwabahlanganyeli abanesifo sikashukela sohlobo lwesibili. Izilingo ezintathu ezisele zihlanganisa nabantu abadala abanempilo. Ukudla okunamandla kanye nezinqubo zokuzila ukudla kwalandelwa umjikelezo ngamunye wokuhlola.
Imiphumela yokucwaninga iboniswe ukuthatha amathisipuni amabili eviniga ne- carbohydrate eyinkimbinkimbi yokudla impendulo yokunciphisa iglycemic okungcono kunokudla iviniga yedwa. Enye imiphumela yabonisa uviniga odlayo nge ushukela olula njengezithelo azishintsanga impendulo ye-glycemic. Ngokuvamile, impendulo ye-glycemic ithuthukiswe ngamaphesenti angu-20 kwabahlanganyeli abadla iviniga ne-carbohydrate eyinkimbinkimbi.
I-American Diabetes Association (ADA) yanyathelisa ucwaningo olubonisa uviniga njengendlela yokusiza abantu abane-type 2 yesifo sikashukela. Inhloso yocwaningo kwakuwukunquma ukuthi uviniga uthathwe ngesikhathi sokulala unganciphisa ukugaya i-glucose kulabo ababhekene nohlobo lwesifo sikashukela.
Abahlanganyeli bokutadisha babengaphansi kwe-non-insulin futhi banamadoda amane nabesifazane abayisikhombisa abaneminyaka engu-40-72. Babethelwe ukuba balandele ukulungiswa okunamandla kokulandelana nokugaya i-glucose kwalinganiswa ngezinsuku ezintathu ezilandelanayo ngaphambi kokuhlolwa.
Abahlanganyeli babedla ukudla okufanayo nezinani ezithile ze-carbohydrates, amaprotheni namafutha. Ngesikhathi sokuvivinywa kwezinsuku ezimbili, izisebenzi zokuzithandela zanikezwa ama-tablespoons amabili kaviniga noma amanzi kanye ne-ounce eyodwa ushizi ngesikhathi sokulala.
Labo abaphuza uviniga ngaphambi kokulala babenciphise ukuphuza kwe-glucose ngamaphesenti ayisithupha uma kuqhathaniswa nabaphuza amanzi. Abacwaningi bakhombise ukuthi i-acetic acid eviniga yasiza ukunciphisa umthwalo ushukela ekudleni ukudla okunamandla. Nakuba kunezinye izifundo ezidingekayo, kubonakala sengathi uviniga ngesikhathi sokulala unethonya elihle ekukhuleni kwamazinga e-glucose kubantu abane-type 2 yesifo sikashukela.
Ingabe Zonke Iviniga Elifanayo?
Uviniga uboniswa ukukusiza ulahlekelwe amafutha omzimba kodwa kunezinhlobonhlobo ezikhethwayo ngenxa yokwehliswa. Ukuphuka ingilazi yokudubula kungase kube yinto engathandeki kakhulu ngenxa yokunambitheka okunamandla. Ngisho noma ngabe ubambe iphunga lakho ukuze liwehlise phansi, abantu abaningi basagijimela endlini yokugezela nge-refag gag.
Uviniga usho 'iwayini elimuncu' futhi kuye ngokuthi okuqukethwe kwe-acetic acid (3-9% ngevolumu) kuyodla amandla. Okulandelayo kukhona izinhlobo ezivame kakhulu zokuviniga ezinhlobonhlobo zezempilo:
- I-Apple cider uviniga (I-ACV) - ethandwa kakhulu futhi iphandwa kakhulu ngezinzuzo zezempilo kanye nokuxiliswa kwamafutha. I-ACV iboniswa ukuvimbela inzuzo yesisindo ngokulawula amafutha ne-sugar metabolism.
- Iviniga yamapomegranate - ecebile kuma-antioxidants nama-flavonoids. Ukucwaninga kusikisela ukuthi kuvusa ama-enzyme esiza ukuphuka nokushisa amafutha omzimba.
- I-Ginseng persimmon uviniga - iboniswe ukuthi ithonye izakhi zofuzo ezihilelekile ku-glucose kanye ne-fat metabolism futhi zibe nethonya elihle ekulahlekeni kwesisindo.
Ama-vinegar ajwayelekile angama kusuka ku-isipuni kuze kufike isipuni esithathwe ngengilazi yamanzi kuze kube kathathu ngosuku. Uviniga ungabuye ujabule futhi uvame ukwenziwa uhlanganiswe namafutha omnqumo futhi ugcoke ngemifino yesaladi.
Imiphumela emibi ekhona yokuphuza iviniga elihlanjululwe ingafaka:
- I-nausea nokuhlanza
- Isisu sithukuthele
- Ukucasuka okukhulu
- Ukukhushulwa koqweqwe lwawo lwamazinyo (amanani aphezulu)
- Amazinga we-potassium aphansi
- Hlangana nemithi ethile (i-insulin, i-blood thinners, i-diuretics)
- Ukulimala kwesifo (uma uphuza uviniga oqondile)
