Selenium lijong

Selenium ke letsoai la bohlokoa. Sena se bolela hore 'mele oa hau o tlameha ho fumana diminerale ena lijong tseo u li jang. Selenium e nyane e loketse bophelo ba hau.

Selenium ke lets'oao la liminerale. 'Mele oa hau oe hloka ka bongata bo fokolang.

Selenium e thusa 'mele oa hau ho etsa liprotheine tse khethehileng, tse bitsoang li-enzyme tsa antioxidant. Tsena li bapala karolo ea ho thibela tšenyo ea lisele.

Phuputso e 'ngoe e bontša hore selenium e ka thusa ka tse latelang:

• Thibela mefuta e meng ea kankere
• Sireletsa 'mele liphellong tse chefo tsa tšepe tse matla le lintho tse ling tse kotsi

Ho hlokahala lithuto tse ling ka melemo ea selenium. Hajoale ho nka tlatsetso ea selenium ho tlatselletsa le mehloli ea lijo tsa selenium ha ho khothaletsoe hajoale bakeng sa maemo ana.

Lijo tsa limela, joalo ka meroho, ke tsona mohloli o tloaelehileng oa lijo tsa selenium. Hore na selenium e kae meroho eo u e jang e ipapisitse le hore na diminerale e ne e le bokae mobung oo limela li holileng ho oona.

Linate tsa Brazil ke mohloli o motle haholo oa selenium. Litlhapi, likhofu, nama e khubelu, lijo-thollo, mahe, khoho, sebete le konofolo le tsona ke mehloli e metle. Lijo tse hlahisoang ke liphoofolo tse jeleng lithollo kapa limela tse fumanoeng mobung o nang le selenium li na le maemo a phahameng a selenium.

Tomoso ea Brewer, kokoana-hloko ea koro le bohobe bo nonneng le tsona ke mehloli e metle ea selenium.

Ho haella ha selenium ho fumaneha seoelo bathong ba United States. Leha ho le joalo, khaello e ka hlaha ha motho a fepuoa ka mothapo (IV line) nako e telele.

Lefu la Keshan le bakoa ke khaello ea selenium. Sena se lebisa ho sa tloaelehang ha mesifa ea pelo. Lefu la Keshan le bolaile mafu a mangata a bongoana Chaena ho fihlela sehokelo sa selenium se sibolloa mme ho fanoa ka litlatsetso.

Maloetse a mang a mabeli a hokahantsoe le khaello ea selenium:

• Lefu la Kashin-Beck, le hlahisang lefu la manonyeletso le masapo
• Cretinism e sa tloaelehang e hlahisang kholofalo ea kelello

Mathata a matla a mala a ka boela a ama bokhoni ba 'mele ba ho monya selenium. Mathata a joalo a kenyelletsa lefu la Crohn.

Selenium e ngata haholo maling e ka baka boemo bo bitsoang selenosis. Selenosis e ka baka ho lahleheloa ke moriri, mathata a lipekere, ho nyekeloa ke pelo, ho teneha, mokhathala le tšenyo e mpe ea methapo. Leha ho le joalo, chefo ea selenium ha e fumanehe hangata United States.

Litekanyo tsa selenium, hammoho le limatlafatsi tse ling, li fanoa ho Dietary Reference Intakes (li-DRIs) tse ntlafalitsoeng ke Boto ea Lijo le Phepo ho Setsi sa Bongaka. DRI ke lentsoe bakeng sa lethathamo la litlatsetso tse sebelisetsoang ho rala le ho lekola phepelo ea limatlafatsi tsa batho ba phetseng hantle.

Hore na o hloka vithamine e kae ho latela lilemo tsa hau le thobalano. Lintho tse ling, joalo ka ho ima le mafu, le tsona li bohlokoa. Basali ba imeng kapa ba anyesang ba hloka chelete e ngata. Botsa mofani oa tlhokomelo ea bophelo hore na ke chelete e kae eu loketseng. Litekanyetso tsena li kenyelletsa:

• Khothaletso e fanoeng ea Dietary Allowance (RDA): Karolelano ea boemo ba letsatsi le letsatsi ba ho noa bo lekane ho fihlela litlhoko tsa limatlafatsi tsa batho ba phetseng hantle (97% ho ea 98%). RDA ke boemo ba ho kenella bo ipapisitseng le bopaki ba lipatlisiso tsa mahlale.
• Ho noa ho lekaneng (AI): Boemo bona bo theoa ha ho se na bopaki bo lekaneng ba lipatlisiso tsa mahlale ho hlahisa RDA. E behiloe boemong boo ho nahanoang hore bo netefatsa phepo e nepahetseng.

Masea (AI)
