Mu thupi la munthu, pali zinthu zambiri zomwe zimakwaniritsa izi kapena zomwe zimagwira ntchito. Ntchito yofunika kwambiri imayimbidwa ndi melanin, yomwe ili ndi chitetezo ku mazira oopsa a ultraviolet. Ndi iye yemwe amateteza khungu kutentha ndi kutembenuza kutentha komwe kumayendetsedwa ndi mphamvu ya Dzuwa kukhala gwero la kutentha kwa dzuwa. Inde, munthu aliyense amakhala ndi dzuwa nthawi yayitali mwa njira yake, choncho ngati mwadzidzidzi amachititsa kuti ziwotche, izi zikuwonetsa m'munsi mwa pigment iyi.
Ndi zakudya ziti zomwe zili ndi melanin?
Timagwiritsidwa ntchito pokwaniritsa zokhudzana ndi zinthu zina zomwe zili ndi zofunika. Komabe, atafunsidwa kuti melanin ili ndi chiyani, ambiri amavutika kuti ayankhe. Izi ndi zomveka, chifukwa, ngati zatuluka, pigment iyi sichipezeka mu chakudya, imapangidwa ndi thupi lomwelo, ndipo munthu amatha kuthandizira maphunziro ake okha. Monga momwe, pakuwonekera kwa kuchuluka kokwanira kwa melanin, m'pofunika kumvetsera zinthu zomwe zili ndi amino acid monga tryptophan ndi tyrosine. Zokambirana zawo zimatsimikiziranso kuti izi zikuchitika bwino. Zakudyazi ziyenera kuphatikizapo mankhwala ochuluka mofanana, chifukwa simungachoke m'thupi popanda mavitamini.
Amino acid yoyamba, yomwe imathandiza kupanga melanin,
Koma tyrosine, imapezeka mu chakudya cha nyama ndi masamba (nyama, nsomba, zipatso). Pamodzi iwo angapezeke mu nthochi ndi nkhanu. Kuti melanin ioneke m'thupi nthawi, muyenera kumvetsera chakudya, chomwe chili ndi mavitamini ena. Kawirikawiri zimakhala za tirigu, zomera, zipatso zam'maluwa ndi zamasamba, zomwe mungapeze mavitamini A , B10, C, E ndi carotene.
Zonsezi pamodzi zimathandiza munthu kukweza mlingo wa melanin m'thupi lawo.
