\"mangan\"Mineralne ili neorganske materije su nezamjenljivi sastojci hrane. Nemaju energetsku vrijednost, ali ipak u\u010destvuju u \u017eivotno va\u017enim procesima u organizmu \u010dovjeka: izgradnji kostiju, odr\u017eavanju kiselo-bazne ravnote\u017ee, sastava krvi, normalizaciji razmjene vode i soli, radu nervnog sistema. U zavisnosti od njihove koli\u010dine u organizmu, dijele se na makroelemente (kalcij, fosfor, magnezij, \u017eeljezo, kalij, natrij, klor, sumpor, \u010dija se koli\u010dina izra\u017eava u gramima), mikroelemente (jod, fluor, bakar, kobalt, mangan, cink, hrom, selen i drugi, \u010dija se koli\u010dina izra\u017eava u miligramima ili dijelovima miligrama) i elemente u tragovima (zlato, radij, \u017eiva i drugi, kojih ima u zanemarljivo malim koli\u010dinama, ali ipak imaju visoku biolo\u0161ku aktivnost). Jedan od mikroelemenata \u010dija je uloga u organizmu postala jasna slu\u010dajno, i to tek sedamdesetih godina pro\u0161log vijeka, je mangan.<\/h3>\n

Prilikom prou\u010davanja metabolizma vitamina K u organizmu nau\u0161nici su slu\u010dajno ustanovili \u010dime se manifestira nedostatak mangana u ishrani. Naime, jednom ispitaniku nisu ga dodavali u poseban na\u010din ishrane kojim su ispitivali metabolizam vitamina K, i zaklju\u010dili da je on, posle 17 tjedana, koliko je istra\u017eivanje trajalo, dobio laki osip, kosa mu je od crne postala \u017eu\u0107kasta i rasla je mnogo sporije, kao i nokti i brada, patio je od napada povra\u0107anja i mu\u010dnine, snizio mu se nivo triglicerida u krvi i oslabio je.<\/p>\n

Tako se do\u0161lo do zaklju\u010dka da je organizmu mangan neophodan radi pravilnog metabolizma masno\u0107a, za izgradnju kostiju, vezivnih tkiva, za proizvodnju energije, sintezu holesterina i nukleotida (DNK), neophodnih svakoj \u017eivoj \u0107eliji za dijeljenje. On se u organizmu prete\u017eno nalazi u \u0107elijama jetre, pankreasa, bubrega i kostiju. Smatra se da se uravnote\u017eenom ishranom unosi dovoljno mangana, a potrebe se kre\u0107u oko dva do pet miligrama dnevno. Ima ga u integralnim \u017eitaricama, vo\u0107u, zelenom povr\u0107u (posebno \u0161pinatu), suhom bobi\u010dastom vo\u0107u (prije svega borovnicama i kupinama), \u010daju, \u0111umbiru i karanfili\u0107u. S obzirom na to da postoji veza izme\u0111u mangana i \u017eeljeza, mo\u017ee se desiti da se kod onih kod kojih do\u0111e do deficita \u017eeljeza u organizmu (krvi), usvaja vi\u0161e mangana, uz mogu\u0107nost intoksikacije. S druge strane, ako je organizam \u201cpreoptere\u0107en\u201d \u017eeljezom, mogu\u0107nost usvajanja mangana se smanjuje, \u0161to mo\u017ee dovesti do njegovog nedostatka. Simptomi, pored ve\u0107 spomenutih iz eksperimenta, su i krhkost kostiju, netolerancija prema \u0161e\u0107eru, visok nivo kolesterola, degeneracija spolnih \u017elijezda. Na intoksikaciju manganom ukazat \u0107e gubitak apetita, halucinacije, smanjenje sposobnosti procjene situacije i zaboravnost, pospanost i bolovi u mi\u0161i\u0107ima.<\/p>\n","protected":false},"excerpt":{"rendered":"
