I-Melanin i-pigment egcwala umzimba womuntu. Itholakala ku-iris yamehlo, izinwele nesikhumba. I-Melanin ivikela umzimba emisebeni ye-ultraviolet, amagciwane kanye nemisebe yomsakazo. Futhi kusiza ukuthenga i-tan enkulu.
Uma kukhona ukuthambekela kokushisa okungapheli, ukushisa kwelanga okubi futhi isikhumba sibucayi kakhulu, lokhu kubonisa ukuthi umzimba unezinga eliphansi le-melanin. Iyancipha ngokuguga, okubangela ukukhonsa nokubonakala kwamakhasha amhlophe esikhumbeni. Ukuze uqonde ukuthi ungakhuphula kanjani izinga le-melanin, kubalulekile, okokuqala, ukwazi ukuthi ikuphi.
Yikuphi ukudla okuqukethe i-melanin?
Okokuqala, kufanelekile ukunaka ukudla kwakho. Okokuqala, kubalulekile ukukhipha iziphuzo ezidakayo, izitsha ezibandayo nezokubhema. Futhi, awukwazi ukudla ukudla okufaka izithasiselo ezihlukahlukene ezifana nama-dyes, amakha, ama-flavor enhancers nabanye.
Uma sicabanga ngemikhiqizo ekhona i-melanin, kufanele kubone ukuthi ukwakheka kwayo emzimbeni kwenzeka lapho ama-amino acids amabili ehlangana: i-tryptophan ne-tyrosine. Kulokhu sithola lokho, ngaleyo ndlela, imikhiqizo equkethe i-melanin ayikho. Kodwa ukuze kusebenze ukukhiqizwa kwaleli pigment, kufanele udle lezo zokudla ezinokubunjwa kwazo, lezi amino acid.
Kubaluleke kakhulu ukuthi imenyu ilinganiswe, ngoba umzimba udinga amavithamini namaminerali ahlukene. Kudingeka ekudleni kwansuku zonke kufanele kube khona izithelo nemifino enemibalabala, imikhiqizo yobisi nemikhumbi.
I-Tyrosine itholakala emikhiqizweni yemvelaphi yezilwane: inyama, inhlanzi, ingulube nenyama yesibindi. Le-amino acid itholakala ekutheni izitshalo ezifana nama-alimondi, ubhontshisi, amagilebhisi nama-avocados.
Ngaphezu kwalokho, ukuhlanganiswa kokubili ama-acids ku-ubhanana nama-peanut.
Ngaphandle kokuhlanganyela kwamavithamini A, B10, C, E, i-carotene, ukukhiqizwa kwe-melanin akunakwenzeka. Kukhona lawa mavithamini okusanhlamvu, okusanhlamvu, amakhambi nemifino. Imithombo ye-carotene yizo izithelo nemifino yezithelo ze-orange, isibonelo, ama-peaches, ama-apricot, ithanga, i-melon, i-orange, izaqathe.
Futhi ungakhohlwa ukuhamba kwansuku zonke emoyeni omusha, ikakhulukazi esimweni sezulu esishisayo. Njengoba imisebe yelanga ilithonya kakhulu ukukhiqizwa kwe-melanin, kuyoba usizo kakhulu ukushisa ilanga ngesikhathi sokuqala kosuku.
