I-Ketosis yindawo yemvelo yokutya.

Kubandakanya umzimba ukuvelisa imizimba ye-ketone kumanqatha kunye nokuwasebenzisela amandla endaweni yee-carbs. Unokungena kwi-ketosis ngokulandela i-carb ephantsi kakhulu, ukutya okunamafutha aphezulu ketogenic ().

Ukutya kwe ketogenic kunokukunceda ukunciphisa umzimba. Ngexesha elifutshane, unganciphisa ubunzima ngokukhawuleza, kuba kunciphisa iivenkile zomzimba zeglycogen kunye namanzi.

Kwixesha elide, inokucinezela ukutya kwakho okukhokelela kukutya okuncinci kweekhalori.

Kanye negalelo ekulahlekeni kwesisindo, i-ketosis inokuba neenzuzo ezininzi zezempilo, njengokunciphisa ukuxhuzula kubantwana abanesathuthwane ().

I-Ketosis inzima kakhulu, kodwa eli nqaku lichaza ukuba liyintoni kwaye linokukunceda njani.

Yintoni i-ketosis?

I-Ketosis yimeko ye-metabolic apho kukho uxinzelelo oluphezulu lweetoni egazini. Oku kwenzeka xa amanqatha ebonelela ngamafutha omzimba, kwaye kukho ukufikelela okulinganiselweyo kwiswekile. Iswekile yegazi (iswekile yegazi) yeyona ndawo ikhethwayo yokufumana iiseli ezininzi emzimbeni.

I-ketosis ihlala inxulunyaniswa nokutya kwe-ketogenic kunye ne-carb ephantsi kakhulu. Kuyenzeka nangexa lokukhulelwa, usana, ukuzila ukutya kunye nendlala (,,,).

Ukuze i-ketosis iqale, ngokuqhelekileyo kufuneka udle ngaphantsi kwama-50 amagremu we-carbs ngosuku kwaye ngamanye amaxesha ungaphantsi kwama-20 amagremu ngosuku. Nangona kunjalo, ukutya ngokuthe ngqo okuza kubangela ukuba i-ketosis ihluke phakathi kwabantu.

Ukwenza oku, kuya kufuneka ususe izinto ezithile ekutyeni, ezinje:

• iinkozo
• ilekese
• iziselo ezineswekile

Kuya kufuneka unciphise:

• iimbotyi
• iitapile
• isiqhamo

Xa usitya ukutya okune-carb ephantsi kakhulu, amanqanaba ehomoni ye-insulin ayehla kwaye ii-acid ezinamafutha zikhutshwa kwiindawo ezigcina amanqatha emzimbeni izixa ezikhulu.

Uninzi lwezi fatty acids zithuthwa ziye esibindini, apho zixutywe khona zaze zaguqulwa zaba zii ketoni (okanye imizimba ye ketone). Ezi molekyuli zinokubonelela ngamandla emzimbeni.

Ngokungafaniyo nee-acid ezinamafutha, iithoni zinokuwela isithintelo segazi-kunye nokubonelela amandla engqondo xa kungekho glucose.

I-Ketosis yimeko ye-metabolic state apho ietoni ziba ngumthombo obalulekileyo wamandla emzimbeni nasengqondweni. Oku kwenzeka xa ukutya kwe-carb kunye ne-insulin iphantsi.

Iiketoni zinokubonelela ngamandla engqondo

Kukungaqondi okuqhelekileyo ukuba ingqondo ayisebenzi ngaphandle kwee-carbs zokutya.

Kuyinyani ukuba i-glucose iyakhethwa kwaye ezinye iiseli kwingqondo zinokusebenzisa iswekile kuphela kumafutha.

Nangona kunjalo, inxalenye enkulu yengqondo yakho inokusebenzisa ietoni zamandla, njengaxa ulambile okanye xa ukutya kwakho kuncinci kwi-carbs ().

Ngapha koko, emva kweentsuku ezintathu kuphela zendlala, ingqondo ifumana i-25% yamandla ayo kwietoni. Ngexesha lendlala yexesha elide, eli nani lenyuka liye kufikelela kwi-60% (,).

Ukongeza, umzimba wakho unokusebenzisa iiprotein okanye ezinye iimolekyuli ukuvelisa iswekile esadinga ubuchopho ngexesha le-ketosis. Le nkqubo ibizwa ngokuba yi-gluconeogenesis.

I-Ketosis kunye ne-gluconeogenesis zikwazi ukufeza iimfuno zamandla engqondo.

Nalu ulwazi oluthe kratya malunga nokutya kwe-ketogenic kunye nengqondo: Ukutya okuneCarb ephantsi kunye neKetogenic kukhulisa njani impilo yeBhongo.

Xa ingqondo ingafumani glucose yaneleyo, inokusebenzisa ietoni zamandla. Iswekile esayifunayo inokuveliswa kwiprotein okanye eminye imithombo.

I-Ketosis ayifani ne ketoacidosis

Abantu bahlala bedibanisa i-ketosis kunye ne-ketoacidosis.

Ngelixa i-ketosis iyinxalenye ye-metabolism eqhelekileyo, i-ketoacidosis yimeko enobungozi yokuchaphazela umzimba enokubulala xa inganyangwa.

Kwi ketoacidosis, igazi liphuphuma ngamanzi kakhulu amanqanaba aphezulu eswekile (iswekile esegazini) kunye neetone.

Xa oku kusenzeka, igazi liba neasidi, eyingozi kakhulu.

I-Ketoacidosis ihlala inxulunyaniswa nohlobo lwesifo seswekile esingalawulwayo. Inokwenzeka nakwabantu abane-2 yeswekile, nangona oku kungaqhelekanga ().

Ukongeza, ukusebenzisa kakubi utywala kunokukhokelela kwi-ketoacidosis ().

I-Ketosis yimeko ye-metabolic state, ngelixa i-ketoacidosis yimeko enzima yonyango esoloko ibonwa kuhlobo lwe-1 yeswekile engalawulwa kakuhle.

Iziphumo kwisifo sokuwa

Isathuthwane sisifo sengqondo esibonakaliswa kukuxhuzula okuphindaphindayo.

Yimeko exhaphake kakhulu yemithambo-luvo, echaphazela abantu abazizigidi ezingama-70 kwihlabathi liphela ().

Uninzi lwabantu abanesathuthwane basebenzisa amayeza okulwa ukuxhuzula ukunceda ukulawula ukuxhuzula. Nangona kunjalo, malunga neepesenti ezingama-30 zabantu bayaqhubeka nokuxhuzula ngaphandle kokusebenzisa la mayeza ().

Ekuqaleni kwee-1920, ukutya kwe-ketogenic kwaziswa njengonyango lwesifo sokuwa kubantu abangaphenduliyo kunyango lweziyobisi ().

Isetyenziswe ikakhulu ebantwaneni, kunye nezifundo ezithile zibonisa izibonelelo. Uninzi lwabantwana abanesathuthwane babone ukuncipha okubonakalayo xa belandela ukutya kwe-ketogenic, kwaye abanye babone uxolelo olupheleleyo (,,,).

Ukutya kwe-Ketogenic kunokunciphisa ngokufanelekileyo ukuxhuzula kwesithuthwane, ngakumbi abantwana abanesifo sokuwa abangaphenduliyo kunyango oluqhelekileyo.

Iziphumo ekulahlekeni kobunzima

Ukutya okune-ketogenic sisidlo esithandwayo sokulahleka kobunzima, kwaye uphando lubonakalisile ukuba lunokusebenza ().

Olunye uphononongo lufumanise ukuba ukutya kwe ketogenic kuluncedo kakhulu ekunciphiseni ukutya kunamafutha asezantsi (,,).

Olunye uphononongo luchaze amaxesha angama-2.2 okwehla kobunzima kubantu abakukutya okune-ketogenic, xa kuthelekiswa nalawo anamafutha asezantsi, ukutya okunomda wekhalori ().

Ngaphezulu, abantu bathambekele ekubeni bazive belambile kwaye bezele kukutya kwe-ketogenic, okubangelwa yi-ketosis. Ngesi sizathu, akuyomfuneko ukubala iikhalori kolu hlobo lokutya (,).

Nangona kunjalo, kuyaziwa ngokubanzi ukuba ukuhambelana nokutya kubaluleke kakhulu kwimpumelelo yexesha elide. Abanye abantu banokukufumanisa kulula ukubambelela kwisondlo se-ketogenic, ngelixa abanye banokufumanisa ukuba ayinakuzinza.

Olunye uphando lubonisa ukuba ukutya kwe keto akunakuba yeyona ndlela ilungileyo yokunciphisa umzimba. Ababhali bovavanyo lwe-2019 bagqibe kwelokuba bekungangcono kunezinye izidlo ekuncedeni abantu ukuba banciphise ubunzima, kwaye isenokungabi nazibonelelo ezithile kubantu abanengxaki yokuphazamiseka emzimbeni (26).

Iinkcukacha ezithe kratya apha: Ukutya kweKetogenic yokuNciphisa ubunzima kunye nokulwa nezifo.

Olunye uphononongo lubonisa ukuba ukutya kwe-ketogenic kukhokelela ekunciphiseni ubunzima bomzimba kunokutya okunamafutha asezantsi. Ukongeza, abantu baziva belambile kancinci kwaye banelisekile.

Ezinye izibonelelo zempilo ze-ketosis

Abanye oososayensi bacebise ukuba ukutya kwe-ketosis kunye ne-ketogenic kunokuba nezinye iziphumo zonyango, nangona kufanelekile ukuba uqaphele ukuba ayizizo zonke iingcali ziyavumelana koku (, 26).

• Isifo sentliziyo: Olunye uphononongo oludala lucebisa ukuba ukunciphisa ii-carbs ukufezekisa i-ketosis kunokuphucula imeko yomngcipheko wesifo sentliziyo njenge-triglycerides yegazi, i-cholesterol iyonke, kunye ne-cholesterol ye-HDL. Nangona kunjalo, uphononongo lwango-2019 lubonisa ukuba abantu abakukutya okune-carb ephantsi kakhulu banokuphulukana nokutya okusempilweni, njengokutya okuziinkozo kunye neempundu (26,,).
• Uhlobo lwe-2 yeswekile: Ukutya kunokuphucula ubuntununtunu be-insulin kunye nemingcipheko eyahlukeneyo enokukhokelela kuhlobo lwe-2 yeswekile, kubandakanya ukutyeba kakhulu (,,).
• Isifo sikaParkinson: Isifundo esincinci safumanisa ukuba iimpawu zesifo sika-Parkinson ziphuculwe emva kweentsuku ezingama-28 kwisidlo se-ketogenic ().

Ukutya kwe-ketosis kunye ne-ketogenic kunokunceda kwizifo ezininzi ezingapheliyo.

Ngaba i-ketosis inayo nayiphi na imiphumo emibi yempilo?

Ngelixa ukutya kwe ketogenic kunokuba nezibonelelo zempilo kunye nokulahleka kobunzima, inokubangela nemiphumela emibi.

Iziphumo zexesha elifutshane zibandakanya intloko ebuhlungu, ukudinwa, ukuqhina, amanqanaba aphezulu e-cholesterol, kunye nomoya ombi (,), kodwa ezi zihlala zinyamalala kwiintsuku nje ezimbalwa okanye iiveki zokuqala ukutya.

Kwakhona, kunokubakho umngcipheko wokuphuhlisa amatye ezintso (,,).

Ngelixa uncancisa, abanye abantu basetyhini baye bavelisa i-ketoacidosis, mhlawumbi ngenxa ye-carb ephantsi okanye ukutya kwe-ketogenic (,,).

Abantu abathatha iswekile esehlisa iziyobisi kufuneka babonane nogqirha ngaphambi kokuzama ukutya kwe-ketogenic, kuba ukutya kungasinciphisa isidingo sonyango.

Ngamanye amaxesha ukutya kwe ketogenic kuphantsi kwifayibha. Ngesi sizathu, licebo elilungileyo ukuqinisekisa ukutya ifayibha eninzi, imifuno ephantsi yecarb.

Ezi ngcebiso zilandelayo zinokukunceda uhlale usempilweni ngexesha le-ketosis ():

• Sela amanzi amaninzi, ngakumbi amanzi.
• Thetha nogqirha wakho ngaphambi kokuqala ukutya kwaye ulandele iingcebiso zabo.
• Jonga umsebenzi wakho wezintso ngelixa ulandela ukutya.
• Funa uncedo ukuba unenkxalabo malunga neziphumo ezibi.

I-Ketosis inokuba luncedo kwabanye abantu, kodwa kuya kufuneka ubuze ugqirha wakho ngaphambi kokutshintshela kukutya okune-carb ephantsi kakhulu, ukuba ayikufanelanga.

I-Ketosis ikhuselekile kubantu abaninzi. Nangona kunjalo, abanye abantu banokuba neziphumo ebezingalindelekanga, kubandakanya ukuphefumla kakubi, iintloko, kunye nokuqunjelwa.

Umgca wezantsi

I-Ketosis yimeko ye-metabolic state enokufezekiswa ngokulandela ukutya kwe-ketogenic.

Inokuba nezibonelelo ezahlukeneyo zempilo, kubandakanya:

• ukuhla ukusinda
• amaqondo eswekile esezantsi egazini
• ukunciphisa ukuxhuzula kubantwana abanesathuthwane

Nangona kunjalo, ukulandela ukutya okungqongqo okubangela i-ketosis kunokuba nzima kakhulu, kwaye kunokubakho neziphumo ebezingalunganga. Ukongeza, ayingabo bonke abaphandi abavumayo ukuba ukutya keto yeyona ndlela yokunciphisa umzimba.

I-Ketosis ayiyiyo eyomntu wonke, kodwa inokunceda abanye abantu.
