I-Sugar Isenza njani Ubudala
Ngaba uyayazi ukuba iinyo lakho elimnandi liyakwenza ube ngumdala ngokukhawuleza? Nantsi into oyifunayo ukuba uyazi malunga nenkqubo ebizwa ngokuba yi-theory-linking theory of aging- kunye nendlela ushukela usenza ngayo ubudala.
Yintoni edibeneyo?
Xa ushushu u-anyanisi okanye isonka sesonka, ama-molecule eshukela kwi-intanethi yokutya kwiimodeli zeprotheni. Ukubambisana, okupheka kubizwa ngokuba yi-caramelization, kubangelwa iamolekyuli zeshukela ezinamathelethi eeprotheni.
Xa oko kwenzeka, uluhlu lweempendulo zenzeka, olubizwa ngokuba yi-glycation, ekhokelela kwiimodeli zeeprotheyini ezidibeneyo.
Le ngqungquthela yokuqhagamshelana nomnqophiso yinto yokuba utshintsho lweekhemikhali lufana nalokhu kwenzeka emzimbeni wakho kwaye lunokubangela ukuguga. Inkqubo iyancipha kwaye iyinkimbinkimbi, kodwa ngokuhamba kwexesha, iiprotheni ezininzi kunye ne-DNA kunye nezinye iimolekyuli zemizimba emzimbeni zihlakulela izikhonkco ezingafanelekiyo, ezibizwa ngokuba yi-cross-links, komnye nomnye. Ezi molekyuli ezinqamlezileyo zisebenzisana kakuhle, kwaye xa iifomleksi ezixhamliweyo zaneleyo ziqokelela kwiisisipha ezithile - ezifana ne-cartilage, imiphunga, imirhoxo kunye neetoni-zingabangela iingxaki.
Iziphumo zoqhagamshelwano
Xa kuqukunjelwa i-cross-linking, izicubu ziba lukhuni, kwaye xa izicubu zinyama zingasebenzi ngokufanelekileyo. Uninzi lweempawu zokuguga zinxulumene nokuqina kwama-tissue. I-Cataracts , umzekelo, lukhuni lwamahlo akho 'lens. Ukuqhagamshelana ngokunqamlekileyo kwesikhumba se-protein ye-klafini kuye kwafunyaniswa ukuba kubekho uxanduva lobunzima kunye nolunye utshintsho lwesikhumba olunexesha elidala, kwaye abaphandi bakholelwa ukuba ukuxhumeka kweprotheni kwiindonga zeemithwaba ngenxa ye- atherosclerosis , okanye ukuqina kwamayeza umngcipheko wokuhlaselwa kwintliziyo kunye nesifo, phakathi kwezinye iimeko.
Ukongezelela, ukuxhuma ukuxhumeka kweeprotheni zengqondo kubonakala ngokwemvelo ngokudala, kuxhaswa inkolelo yokunquma ukuguga.
Nciphise phantsi
Ngelixa ungeke uyeke ukudibanisa, ungakunciphisa. Abaphandi bakholelwa ukuba ukuba ingxube yeeshukela egazini iphakamileyo, kubakho ukugqithisana okukhulu. Ukutya okunomlinganiselo ophezulu we-glycemic index, ezifana ne-sugary sodas kunye neentshisi, ukukhulula iswekile emzimbeni ngokukhawuleza.
Ezi zokutya zidibene nesifo senhliziyo, mhlawumbi ngenxa yeprotheyini yokuqhagamshelana. Wonke umntu unokufumana inzuzo yokugcina ushukela wegazi kwi-spiking. Kwaye kunokukunceda ukhangele kwaye uzive uselula!
