I-Melanin i-pigment ezaliswe ngumzimba womntu. Itholakala kwi-iris yamehlo, iinwele kunye nesikhumba. I-Melanin ikhusela umzimba emisebeni ye-ultraviolet, ii-virus kunye ne-rayactive radiation. Kwakhona kunceda ukuthenga i-tan.
Ukuba kukho ukuthambekela kokutshisa ngokusisigxina, ukushona kwelanga kakubi kwaye ulusu lukhuni kakhulu, oko kubonisa ukuba umzimba unomgangatho ophantsi we-melanin. Iyancipha ngeminyaka yobudala, ebangela ukuguquka nokubonakala kwebala elimhlophe kwesikhumba. Ukuze uqonde indlela yokuphakamisa inqanaba le-melanin, kubalulekile, okokuqala, ukuba uyazi apho.
Ziziphi ukutya eziqukethe i-melanin?
Kubaqalayo, kukufanelekile ukunyamekela ukutya kwakho. Okokuqala, kuyimfuneko ukuba ungabandakanyi iziyobisi, izitya ezidibeneyo nezitshisi. Kwakhona, awukwazi ukutya ukutya okubandakanya izithako ezahlukahlukeneyo ezifana needayi, iziqhumiso, i-flavor enhancer nabanye.
Ukucinga ngeemveliso apho kukho i-melanin, kubalulekile ukuba uqaphele ukuba ukubunjwa kwawo emzimbeni kwenzeka xa ezimbini zibandakanya ama-amino acids: tryptophan kunye ne-tyrosine. Kule nto sifumana oko, njengenjalo, iimveliso eziqukethe i-melanin azikho. Kodwa ukuze kusebenze ukuveliswa kwale pigment, kufuneka udle ezo zokutya ezinokubunjwa kwazo, ezi zi-amino acid.
Kubaluleke kakhulu ukuba imenyu ibe nokulinganisela, kuba umzimba ufuna iivithamini ezahlukeneyo kunye neemaminerali. Kubalulekile ekudleni kwansuku zonke kufuneka kubekho iziqhamo nemifuno enemibala, yobisi kunye neemveliso zaselwandle.
I-Tyrosine ifumaneka kwimveliso yesimo semfuyo: inyama, intlanzi, ingulube kunye nesibindi seenkomo. Le nino-amino acid ifumaneka kwizinto zokutya ezifana nezamantyisi, iimbotyi, iidiliya kunye ne-avocados.
Ukongezelela, udibaniso lwama-asidi amabini lulobhanana kunye namanqatha.
Ngaphandle kokuthatha inxaxheba kwamavithamini A, B10, C, E, i-carotene, ukuveliswa kwe-melanin akunakwenzeka. Zikhona ezi iivithamini kwizidalwa, okusanhlamvu, izityalo kunye nemifuno. Imithombo ye-carotene yimiqhamo nemifuno ye- orange ngokuqhelekileyo, umzekelo, iipeaches, i-apricots, ithanga, i-melon, i-orange, izaqathe.
Kwakhona ungakulibali malunga nokuhamba kwansuku zonke emoyeni omtsha, ngokukodwa kwimozulu yelanga. Ekubeni imisebe yelanga ichaphazela kakuhle imveliso ye-melanin, kuya kuba luncedo kakhulu ukushisa ilanga kwixesha lokuqala.
