Ukugquma kwesisu, ukuqunjelwa, isifo sohudo: ukunganyamezeli ifructose kunokuba semva kwezi mpawu. Into ebizwa ngokuba yi-intestinal (okt isuka emathunjini) ukunganyamezeli kwefructose kuxhaphake kakhulu.
Oku kunyamezelwa kwe-fructose kufunyenwe kwinqanaba elithile ebomini - ngokungafaniyo nefom ye-congenital enqabileyo kakhulu (i-hereditary fructose intolerance - HFI). Kuqikelelwa ukuba i-30 ukuya kwi-40 ipesenti yabantu baseMbindi Yurophu abanako ukufunxa i-fructose ngokufanelekileyo ngamathumbu amancinci, oku kubizwa ngokuba yi-fructose malabsorption. Ukuba kukho kwakhona ukuphazamiseka okusebenzayo kwamathumbu, ukusabela kokunganyamezeli kwenzeka.
Ukuphazamiseka kwemetabolism ngunobangela wokunganyamezeli kwefructose
Ngokwahlukileyo kwi-allergies yokutya, ukunganyamezeli akubangelwa kukusabela kokhuselo lwe-immune system, kodwa kukuphazamiseka kwemetabolism. Kwi-fructose malabsorption, ukuxutywa kwe-fructose ukusuka emathunjini ukuya kwigazi kuyaphazamiseka. Udonga lwamathumbu amancinci luqulethe iiprotheni zokuthutha ezithatha izondlo ezivela kwi-chyme kwaye zithuthe ngodonga. Abathuthi abahlukeneyo banoxanduva lwezondlo ezahlukeneyo, i-fructose transporter, umzekelo, ibizwa ngokuba yi-GLUT-5. Ukuba akukho okwaneleyo kubo okanye ukuba baneziphene, i-fructose isala kwi-pulp yokutya kwaye iqhubela phambili emathunjini amakhulu, aphethwe yibhaktheriya. Bayakuvuyela ukutya okuswiti kwaye basebenzise iigesi ezifana ne-hydrogen okanye i-methane kunye ne-short-chain fatty acids, ezinyusa uxinzelelo lwe-osmotic. Oku kubangela iimpawu ezifana ne-flatulence, ukuziva uzele, kunye norhudo.
Ukuxutywa kwe-Fructose kunokuphazamiseka okwethutyana, umzekelo ngenxa yokuphazamiseka kwamathumbu emathunjini emva kokusuleleka kwintsholongwane okanye ukusetyenziswa kwe-antibiotics. Kodwa inokuba sisigxina. Ngokwahlukileyo kwi-HFI yokuzalwa enqabileyo, abo bachaphazelekayo ngokufumana ukunganyamezeli kwe-fructose basenokunyamezela izixa ezishiyekileyo ze-fructose. Ngenxa yokuba ezinye ze-fructose "zinokukhwela-kunye" kwi-glucose transporter GLUT-2. Nge-HFI, kwelinye icala, umzimba ufunxa yonke i-fructose kodwa awukwazi ukuyibuyisela kwakhona. Abantu abane-HFI kufuneka ke ngoko babambelele kukutya okunefructose ephantsi ubomi babo bonke.
Isicaphucaphu, ukuqunjelwa, kunye nokuqaqanjelwa kusenokuba ziimpawu
Iimpawu eziqhelekileyo zenzeka emva kokutya ukutya okuqukethe i-fructose: isicaphucaphu, ukuziva ugcwele, ingxolo yesisu kunye ne-flatulence, isisu esibuhlungu, kunye nohudo.
Ukukhathala, ukugxininiswa okungahambi kakuhle, kunye neenguqu zengqondo ezifana nokudakumba zihlala zihambelana ne-fructose malabsorption. Kuba ukuba i-GLUT-5 ayisebenzi, i-tryptophan ebalulekileyo ye-amino acid ayiyi kufunxwa kakuhle. Kodwa isisandulela seserotonin yokuphucula isimo somzimba, esinika imvakalelo yokuzola, uxolo lwangaphakathi kunye nokwaneliseka.
Ukunganyamezeli kwe-Fructose kunokuqhubela phambili kwi-syndrome yamathumbu enomsindo. Ngokwentelekiso rhoqo, abo bachaphazelekayo nabo bane-folic acid ephantsi kunye namanqanaba e-zinc, nto leyo enokukhokelela kwiimpawu zokunqongophala kunye nokuba sesichengeni sosulelo.
Uvavanyo lokuphefumula kwe-Hydrogen ukuxilongwa
Into ebizwa ngokuba yi-hydrogen breath test ngokuqhelekileyo ilinganisa ukuba i-fructose esetyenzisiweyo ifikelela emathunjini amakhulu - ngokuchasene noko kuhloswe. Ngaphantsi kweliso lonyango, abo bachaphazelekayo bathatha iglasi ye-fructose echithwe emanzini kwisisu esingenalutho. Isiqulatho sehydrogen ekuphefumlweni silinganiswa ngezithuba zeeyure ezimbini kwisithuba seeyure ezimbini. Ngokusekwe kwisiphumo sejika eliqhelekileyo, ugqirha unokugqiba ukuba kukho i-fructose malabsorption. Nangona kunjalo, kuba irhasi yemethane inokwakheka kwihydrogen yibhaktheriya ethile emathunjini, iyavakala ukujonga isixa semethane kumoya ophefumlayo. Oku kuthetha ukuba ukuxilongwa kuxhomekeke kwi-100 ekhulwini.
I-Fructose kwiziqhamo, kodwa nakwizinto ezininzi zokutya ezicutshungulwayo
I-Fructose ayifumaneki kuphela kwiziqhamo, kodwa nakwiminye imifuno kwaye, umzekelo, kwi-honey, iswekile yasekhaya, kwi-sugar invert (isiraphu), isiraphu yengqolowa, kunye ne-inulin, njenge-sugar substitute kwi-confectionery eyahlukeneyo, i-pastries, i-soups esheshayo, kunye nezinye iimveliso ezigqityiweyo. Kwimeko ye-fructose malabsorption, i-sorbitol nayo ayinyamezelwa. I-Sorbitol (E 420) yinto ebizwa ngokuba yi-alcohol yeswekile, efumaneka ngokukodwa kwiziqhamo zepome ezifana namapere, iiapile, iiplums, iipesika kunye neapilkosi. Inokufumaneka kuninzi lokutya okuveliswayo kwimizi-mveliso njengendawo yeswekile okanye i-humectant kwaye isebenza njengomthwali wamayeza. Ngoko ke kuyimfuneko ngokukhawuleza ukuba abo bachaphazelekayo bahlale befunda uluhlu lwezithako xa kuthengwa.
