Ngekhulu le-XIX, i-microelement ye-selenium yafunyanwa ngumsululwazi waseSweden yaye yayithathwa njengetyhefu eyingozi. Kule minyaka, inzululwazi, njengoko kunjalo, iimbono zihluke kakhulu, kwaye ekugqibeleni, ngowe-1980, i-WHO yabona i-selenium njengenxalenye ebalulekileyo yokutya okunempilo. Namhlanje asiyazi nje ngeenzuzo ze-selenium, kodwa kunye nemiphumo emibi ebangelwa ukungabikho kokutya okune-selenium etafileni lethu. Konke oku kulwazi ngoku.
Izinzuzo
Okokuqala, ukusetyenziswa kwemveliso kunye ne-selenium kwandisa imithi yethu. Kwimanani, eli li-77% ngaphantsi kwenkqubo ye-endocrine kunye ne-47% ngaphantsi kwazo zonke ezinye izifo. I-Selenium yiprotheyini eneziganeko zokulwa ne-antioxidant. I-Selenium ikwandisa ukuxhatshazwa kwethu kwiibhaktheriya, iintsholongwane, kuvimbela ukuqokelela kwama-radical ekhululekile emzimbeni.
Le micronutrient iya kukhusela i-UV emisebe ye-UV kunye ne-allergies yamachiza. I-Selenium ibandakanyeka kwi-synthesis yazo zonke i-hormone, kunye nakwiinkqubo ezininzi zezinto eziphilayo zenyama.
Imveliso equkethe i-selenium ibaluleke kakhulu kumgudu womntu wesisu, kuba i-selenium ihlala i-normalizes amathumbu e-Ph, ithatha inxaxheba kwi-microflora ephilileyo kwaye iphucula isondlo seendonga zeembumba. Ukongezelela, i-selenium ingavumeli ukusabalalisa kweefungi ze-pathogenic, ezisoloko ziziqhamo zokubola kunye nezitshalo zentyatyambo esiswini. Ezi fungi zithintela, umzekelo, isibindi.
Kuba besetyhinium abakhulelweyo kubaluleke ngakumbi kunabo bonke abantu. Okokuqala, kuthintela ukuzalwa kwangaphambi kokuzalwa, ukhusela umntwana ekuzalweni ngeziphene, kunye nokufa kwasekusaneni. Isixa selenium ekudleni komama onesibeleko sincike ngokubaluleka kobisi lwebele.
Kwi mveliso
Kwaye ngoku kuphazamiseka: oku kudibeneyo, kuwo onke amagama, amagama, selenium, sidinga kuphela ii-microgramgram eziyi-10 ngosuku. Ngokweminyaka yobudala, ukutyiwa kwe-selenium kufuneka kwandiswe ngokuxhomekeka kubukhulu, umzekelo, iintsana kunye nabantwana abaselula bafuna i-10 μg ye-selenium ukuya kwiinyanga ezili-10, kwaye kwiminyaka emithandathu i-20 μg. Kubantu abadala, i-dose ephezulu ye-trace element kwi-selenium ekudleni i-70 μg, kubafazi abangama-55 μg. Kwaye ngexesha lokukhulelwa kunye ne-lactation, umlinganiselo wenyuka ukuya kuma-200 mcg ngosuku.
I-Selenium ininzi kwimveliso-iimbindi, iintso, imiphunga, iintliziyo. I-selenium ifumaneka kwiintlanzi zaselwandle kunye neentlanzi zasemanzini - i-cod, i-herring, i-flounder, i-sardines, i-salmon, i-mackerel, ityhuna, i- shrimps , i-mussels, i-oyster, i-lobster kunye ngokubanzi nawaphi na ukutya okuloba.
Kufuneka ujonge kwakhona i-selenium enantwini, ininzi yayo ifumaneka kwi-nati ye-Brazil-1530 mcg nge-100 g. Kodwa ekubeni sele uyayazi malunga nemilinganiselo ye-selenium, asikucebisi ukuba nidle ama-nuts aseBrazil ngamanani angaphezu kwe-20-30 g ngosuku. I-Selenium itholakala kwiimvuthu zesiGrisi, iinqununu, iikonkco.
Le nxalenye yokulandelelana ingaphinde ixutywe kumama amaqanda, inkukhu yenkukhu, ushizi. Ukuba ukhetha ukutya kwemifuno, khangela i-selenium kwiminquma kunye neoli yeoli, i-bran, imvubelo ye-brewer, ingqungquthela yengqolowa, irayisi eluhlaza kunye nomgubo, ubhontshisi, i-garlic, i-garlic kunye nezolimo.
Ukugqithisa
Kodwa ngaphambi kokuba sitsho iiphina iimveliso zine-selenium, simele sixelele ukuba i-selenium isasetyhi, kodwa kuphela kwizidakamizwa ezingaphezu kwesiqhelo. I-Selenium evela kwimveliso yokutya ayikwazi ukuba yingozi, ngenxa yokuba umzimba wakho uya kukumisa ukuba uya kuphezulu.
Uvela phi ilahleko?
Kwiminyaka engama-50 edlulileyo akukho mntu uthetha ngokubaluleka kwe-selenium emzimbeni wethu, nangokonakala kwayo. Impendulo ilula: abantu bayabona ukuba into ayiphumekanga xa engekho. Kuze kube kutshanje umhlaba ugcwele i-selenium, kwaye namhlanje isalathisi esivumbileyo somhlaba siphelile kwaye kukho isidingo sokwenza umquba we-selenium, ongacebisi ukutya kwawo konke.
