Ukuzuza ubunzima akuhambelani nobungakanani bokutya?!!

Ukuzuza ubunzima akuhambelani nobungakanani bokutya?!!

Kule mihla, iqela lezazinzulu zaseMelika ziphikisana, kuphononongo olutsha olunokuthi lwanelise icandelo elikhulu labantu, ukuba oonobangela bobhubhani bokutyeba banxulumene kakhulu nomgangatho wezinto esizityayo kunobungakanani bento etyiwayo.

Izibalo ezivela kwi-US Centres for Disease Control and Prevention (CDC) zibonisa ukuba ukukhuluphala kuchaphazela ngaphezu kwe-40% yabantu abadala baseMelika, kubabeka engozini yesifo senhliziyo, isifo, uhlobo lwe-2 yeswekile kunye neentlobo ezithile zomhlaza, ngokutsho kweSciTechDaily.

I-USDA Dietary Guidelines for Americans 2020-2025 ikwathi ukunciphisa umzimba kufuna ukuba abantu abadala banciphise inani leekhalori abazifumana ekutyeni naseziselo kwaye banyuse umzimba.

Indlela yakudala "ye-energy balance".

Le ndlela yokulawula ubunzima nayo isekelwe kwimodeli yokulinganisa amandla kwinkulungwane endala, echaza ukuba ukuzuza ubunzima kubangelwa kukutya amandla amancinci kunalawo adliwayo.

Kwihlabathi lanamhlanje, ngelixa umntu ejikelezwe ngokutya okumnandi kakhulu, okuthengiswa kakhulu kunye nokutya okucutshungulwayo okuncinci, kulula ukuba atye iikhalori ezininzi kunokuba akufunayo, kwaye oku kukungalingani okuye kwandiswa yindlela yokuphila yanamhlanje.

Akukho nto emva kwamashumi eminyaka yokwazisa

Ukusuka kulo mbono, ukutya ngokugqithiseleyo, kunye nokungonelanga komsebenzi womzimba, kukhokelela kubhubhani wokutyeba.

Ngakolunye uhlangothi, ngaphandle kokusasazwa kwemiyalezo yokwazisa ngempilo kumashumi eminyaka ukukhuthaza abantu ukuba batye ukutya okuncinci kwaye bazilolonge ngakumbi, amazinga okutyeba kakhulu kunye nezifo ezinxulumene nokutyeba ziye zanyuka ngokuthe ngcembe.

Abaphandi bophononongo babonisa iziphene ezisisiseko kwimodeli yokulinganisa amandla, besithi enye imodeli, imodeli ye-carbohydrate kunye ne-insulin, ichaza ngcono ukutyeba kunye nokuzuza ubunzima, kwaye ikhomba indlela eya kusebenza ngakumbi, izicwangciso zokulawula ubunzima bexesha elide.

Isantya sokukhula kolutsha

Ngokutsho kombhali okhokelayo wesifundo uDkt David Ludwig, i-endocrinologist kwiSibhedlele sabantwana baseBoston kunye noprofesa kwiSikolo sezoNyango saseHarvard, imodeli yokulinganisa amandla ayinalo uncedo ekuqondeni izizathu zezinto eziphilayo zokufumana ubunzima, ekubeni ngexesha lokukhula, umzekelo, abatsha banokutya ngaphezulu kwe-1000 calories ngosuku. Kodwa akukho siqiniseko enoba ukutya ngokugqithiseleyo kubangela ukukhula ngokukhawuleza okanye ukukhula ngokukhawuleza kwenza okwishumi elivisayo azive elambile yaye etye kakhulu.

Ngokwahlukileyo, i-carbohydrate kunye nemodeli ye-insulin yenza ukuba ithathelwe ngesibindi ingcamango yokuba ukugqithisa akuyona into ebangela ukukhuluphala.

Imodeli ye-carbohydrate-insulin ibeka ityala elininzi lobhubhani wokutyeba ngoku kwiipateni zokutya zanamhlanje ezibonakaliswa kukutya okugqithisileyo okunomthwalo ophakamileyo we-glycemic, phakathi kwabo ngakumbi, ukugaywa ngokukhawuleza kwe-carbohydrates esetyenzisiweyo, ebangela iimpendulo zehomoni ezitshintsha kakhulu inkqubo. Ukusetyenziswa kwemetabolism yomzimba womntu kwaye kukhokelela ekugcinweni kwamafutha, ukufumana ubunzima kunye nokutyeba.

Imfihlelo yokuziva ulambile

Uphononongo lukwacacisile ukuba xa usitya iicarbohydrates ezicutshungulwayo kakhulu, umzimba wonyusa ukukhutshwa kwe-insulin kwaye ucinezela ukukhutshwa kweglucagon, ihomoni ye-peptide eveliswa ziiseli ze-alpha kwi-pancreas.

I-Glucagon iphakamisa i-glucose kunye ne-fatty acids egazini, kwaye umphumo wayo uchasene ne-insulin, ehlisa i-glucose ye-extracellular.

Emva koko inika umqondiso kwiiseli ezinamafutha ukuba zigcine iikhalori ezininzi, zishiya iikhalori ezimbalwa ezifumanekayo kwizihlunu ze-fuel kunye nezinye izihlunu ezisebenzayo. Ingqondo ke iyaqonda ukuba umzimba awufumani amandla aneleyo, nto leyo ekhokelela kwimvakalelo yokulamba.

Imetabolism nayo iyacotha kwilinge lomzimba lokugcina amafutha. Ngaloo ndlela, umntu uyaqhubeka eziva elambile kwaye edla ngakumbi, okukhokelela ekuqhubekeni kokufumana amafutha amaninzi.

Ifomula ebanzi

Ngelixa imodeli ye-carbohydrate-insulin ayintshanga, kunye nemvelaphi yayo ibuyela ekuqaleni kwenkulungwane yamashumi amabini, umbono wophononongo lwamva nje unokuba yeyona nguqulelo ibanzi yale modeli ukuza kuthi ga ngoku, eyathi yabhalwa liqela le-17 kumazwe ngamazwe. izazinzulu ezaziwayo kunye nabaphandi beklinikhi njengeengcali kwinkalo yempilo yoluntu. Ngokudibeneyo, izazinzulu zishwankathela ubungqina obukhulayo obuxhasa imodeli ye-carbohydrate-insulin. Bachonge uthotho lweengqikelelo ezivavanywayo ezibonisa iimodeli ezimbini zokukhokela uphando lwexesha elizayo.

Ukuncipha kwendlala nokubandezeleka

Ukongezelela, izazinzulu zicebise ukuba imodeli ye-carbohydrate-insulin imele enye indlela egxininise ngakumbi kumgangatho kunye nomxholo wezondlo.

Ngokutsho kukaGqr Ludwig, ukunciphisa ukusetyenziswa kwe-carbohydrates ekhawulezayo yokugaya ukutya okukhukula ukutya ngexesha lokutya okunamafutha aphantsi kunciphisa i-primary drive yokugcina amanqatha emzimbeni. Ngaloo ndlela, kunokwenzeka ukuba ulahlekelwe ubunzima obugqithisileyo kunye nemvakalelo encinci yendlala kunye nokubandezeleka.
