Melanin ndi nkhumba yodzazidwa ndi thupi la munthu. Amapezeka m'maso, tsitsi ndi khungu. Melanin imateteza thupi ku mazira a ultraviolet, mavairasi komanso ma radiation. Zimathandizanso kugula tani yakuopsa.
Ngati pali chizolowezi chowotcha nthawi zonse, kutentha kwa dzuwa ndi khungu kumakhala kovuta kwambiri, ndiye izi zimasonyeza kuti thupi liri ndi vuto la melanin. Zimachepa ndi msinkhu, zomwe zimayambitsa mawanga ndi maonekedwe oyera pa khungu. Pofuna kumvetsetsa momwe mungapangire mlingo wa melanin, ndikofunikira, choyamba, kudziwa komwe kuli.
Ndi zakudya ziti zomwe zili ndi melanin?
Poyambira, ndi bwino kumvetsera zakudya zanu. Choyamba, m'pofunika kusiya zakumwa zoledzeretsa, zokazinga ndi zosuta. Komanso, simungadye zakudya zomwe zimaphatikizapo zowonjezereka monga dyes, zonunkhira, zopatsa mphamvu zowonjezera ndi zina.
Poganizira za mankhwala omwe ali ndi melanin, tiyenera kudziŵa kuti mapangidwe ake mumthupi amapezeka pamene awiri amino acid amagwirizana: tryptophan ndi tyrosine. Kuchokera apa timapeza kuti, monga choncho, mankhwala omwe ali ndi melanin salipo. Koma kuti mutsegule mtundu wa pigment uwu, muyenera kudya zakudya zomwe zimapangidwa, izi ndi amino acid.
Ndikofunika kuti mapepala akhale oyenera, chifukwa thupi limasowa mavitamini osiyanasiyana ndi mchere. Zofunikira pa chakudya cha tsiku ndi tsiku ayenera kukhala ndi zipatso zokoma ndi ndiwo zamasamba, mkaka ndi zamadzi.
Tyrosine imapezeka m'zinthu za nyama: nyama, nsomba, nkhumba ndi chiwindi cha ng'ombe. Izi amino acid imapezedwanso mu zakudya zamasamba monga amondi, nyemba, mphesa ndi mapuloteni.
Kuphatikiza apo, kuphatikiza kwa ma asidi onse ndi nthochi ndi nthanga.
Popanda kutenga mavitamini A, B10, C, E, carotene, kupanga melanin sikutheka. Pali mavitamini awa mu tirigu, tirigu, zitsamba ndi nyemba. Zotsatira za carotene makamaka ndiwo zipatso zam'maluwa ndi zamasamba , mwachitsanzo, yamapichesi, apricots, dzungu, vwende, malalanje, kaloti.
Komanso musaiwale za kuyenda tsiku ndi tsiku mu mpweya wabwino, makamaka nyengo ya nyengo. Popeza kuwala kwa dzuŵa kumachititsa kuti melanin ikhale yopangidwa, zimakhala bwino kwambiri kuti dzuwa lisayambe kumayambiriro kwa tsikulo.
