Te pānga o te selenium
Mō te whakatipu kararehe me te heihei
1. Whakapai ake i te mahi whakaputa me te tere hurihanga whāngai;
2. Whakapai ake i te mahi whakaputa uri;
3. Whakapai ake i te kounga o te mīti, te hua manu me te miraka, me te whakapai ake i te ihirangi selenium o ngā hua;
4. Whakapai ake i te hanganga pūmua kararehe;
5. Whakapai ake i te kaha ārai-ahotea o ngā kararehe;
6. Whakatikatika i ngā moroiti puku kia mau tonu ai te hauora o te puku;
7. Whakapai ake i te ārai mate o ngā kararehe…
He aha te pai ake o te selenium waro i te selenium kore-waro?
1. Hei tāpiritanga ā-waho, kāore i teitei ake te bioavailability o te selenium cysteine (SeCys) i tērā o te sodium selenite. (Deagen et al., 1987, JNut.)
2. Kāore e taea e ngā kararehe te hanga tika i ngā selenoprotein mai i ngā SeCys o waho.
3. Ko te whakamahinga whai hua o ngā SeCys i roto i ngā kararehe ka tino tutuki mā te whakarerekētanga anō me te hanganga o te selenium i roto i te ara pākia me roto i ngā pūtau.
4. Ka taea anake te whiwhi i te puna selenium e whakamahia ana mō te rokiroki pumau o te selenium i roto i ngā kararehe mā te whakauru i te raupapatanga hanga o ngā pūmua kei roto te selenium i roto i te ahua o SeMet hei utu mō ngā ngota methionine, engari kāore e taea e SeCys te whakamahi i tēnei ara hanga.
Te ara mimiti o te selenomethionine
Ka mimitia pērā i te methionine, e uru ana ki te pūnaha toto mā te pūnaha pupuhi konutai i roto i te duodenum. Kāore te kukū e pā ki te mimitinga. Nā te mea he waikawa amino nui te methionine, he nui te mimitinga i te nuinga o te wā.
Ngā mahi koiora o te selenomethionine
1. Te mahi ārai mate: Ko te Selenium te pokapū hohe o te GPx, ā, ka whakatinanahia tana mahi ārai mate mā te GPx me te thioredoxin reductase (TrxR). Ko te mahi ārai mate te mahi matua o te selenium, ā, ko ētahi atu mahi koiora e hangai ana ki tēnei.
2. Te whakatairanga i te tipu: He maha ngā rangahau kua whakaatu ko te tāpiri i te selenium waro, te selenium kore-waro rānei ki te kai ka taea te whakapai ake i te tipu o te heihei, te poaka, te ruminant, te ika rānei, pērā i te whakaiti i te ōwehenga o te kai ki te mīti me te whakanui ake i te pikinga o te taumaha o ia rā.
3. Te whakapai ake i te mahi whakaputa uri: Kua whakaatuhia e ngā rangahau ka taea e te selenium te whakapai ake i te nekenekehanga o te parāoa me te maha o ngā parāoa i roto i te parāoa, engari ko te korenga o te selenium ka taea te whakanui ake i te tere o te hanga parāoa; Mā te tāpiri i te selenium ki te kai ka taea te whakanui ake i te tere whakamomona o ngā kau poaka, te whakanui ake i te maha o ngā whānautanga, te whakanui ake i te tere o te whakaputa hua manu, te whakapai ake i te kounga o te anga hua manu me te whakanui ake i te taumaha o te hua manu.
4. Whakapai ake i te kounga o te mīti: Ko te waikura lipid te take matua o te hekenga o te kounga o te mīti, ko te mahi antioxidant selenium te take matua hei whakapai ake i te kounga o te mīti.
5. Te Whakakore i ngā Paitini: Kua whakaatuhia e ngā rangahau ka taea e te selenium te ārai me te whakamama i ngā pānga paitini o te mata, te cadmium, te arsenic, te mercury me ētahi atu huānga kino, te fluoride me te aflatoxin.
6. Ētahi atu mahi: Hei tāpiri, he mahi nui tā te selenium ki te ārai mate, te whakatakoto selenium, te whakaputanga homoni, te mahi whākōkī nakunaku, me ētahi atu.
