Zotsatira za selenium
Za ziweto ndi nkhuku
1. Kukweza magwiridwe antchito a zokolola ndi kuchuluka kwa chakudya chosinthidwa;
2. Kupititsa patsogolo ntchito yobereka;
3. Kukweza ubwino wa nyama, mazira ndi mkaka, ndikukweza kuchuluka kwa selenium m'zinthu zomwe zimapangidwa;
4. Kupititsa patsogolo kapangidwe ka mapuloteni a nyama;
5. Kupititsa patsogolo luso la nyama loletsa kupsinjika maganizo;
6. Sinthani tizilombo toyambitsa matenda m'matumbo kuti matumbo akhale ndi thanzi labwino;
7. Kulimbitsa chitetezo chamthupi cha ziweto…
Chifukwa chiyani selenium yachilengedwe ndi yabwino kuposa selenium yopanda organic?
1. Monga chowonjezera chakunja, kupezeka kwa selenium cysteine (SeCys) sikunali kokwera kuposa kwa sodium selenite. (Deagen et al., 1987, JNut.)
2. Nyama sizingathe kupanga ma selenoprotein mwachindunji kuchokera ku ma SeCy akunja.
3. Kugwiritsa ntchito bwino kwa SeCys mwa nyama kumapezeka kwathunthu kudzera mu kusinthidwanso ndi kupanga selenium mu njira ya kagayidwe kachakudya ndi m'maselo.
4. Dziwe la selenium lomwe limagwiritsidwa ntchito posungira selenium mokhazikika m'zinyama lingapezeke kokha poika njira yopangira mapuloteni okhala ndi selenium mu mawonekedwe a SeMet m'malo mwa mamolekyu a methionine, koma SeCys sangagwiritse ntchito njira yopangira iyi.
Njira yoyamwitsa selenomethionine
Imayamwa mofanana ndi methionine, yomwe imalowa m'magazi kudzera mu sodium pumping system mu duodenum. Kuchuluka kwake sikukhudza kuyamwa kwa methionine. Popeza methionine ndi amino acid yofunika kwambiri, nthawi zambiri imayamwa kwambiri.
Ntchito za selenomethionine m'thupi
1. Ntchito Yoteteza Kutupa: Selenium ndiye pakati pa GPx, ndipo ntchito yake yoteteza ku kutupa imachitika kudzera mu GPx ndi thioredoxin reductase (TrxR). Ntchito yoteteza ku kutupa ndiyo ntchito yaikulu ya selenium, ndipo ntchito zina zamoyo zimadalira kwambiri izi.
2. Kukulitsa kukula: Kafukufuku wambiri wasonyeza kuti kuwonjezera selenium yachilengedwe kapena selenium yopanda organic muzakudya kungathandize kuti nkhuku, nkhumba, nyama zolusa kapena nsomba zikule bwino, monga kuchepetsa chiŵerengero cha chakudya ndi nyama ndikuwonjezera kulemera kwa tsiku ndi tsiku.
3. Kubereka bwino: Kafukufuku wasonyeza kuti selenium imatha kusintha kuyenda kwa umuna ndi kuchuluka kwa umuna mu umuna, pomwe kusowa kwa selenium kumatha kuonjezera kuchuluka kwa umuna wosakhwima; Kuwonjezera selenium muzakudya kungapangitse kuti mbeu za nkhumba zibereke bwino, kuwonjezera kuchuluka kwa ana, kuwonjezera kuchuluka kwa mazira, kuwonjezera ubwino wa chipolopolo cha dzira ndikuwonjezera kulemera kwa dzira.
4. Kukweza ubwino wa nyama: Kuchuluka kwa mafuta m'thupi ndiye chinthu chachikulu chomwe chimapangitsa kuti ubwino wa nyama uchepe, ndipo ntchito ya selenium yoletsa kutupa ndiyo chinthu chachikulu chomwe chimapangitsa kuti ubwino wa nyama ukhale wabwino.
5. Kuchotsa poizoni m'thupi: Kafukufuku wasonyeza kuti selenium imatha kuletsa poizoni wa lead, cadmium, arsenic, mercury ndi zinthu zina zoopsa, fluoride ndi aflatoxin.
6. Ntchito zina: Kuphatikiza apo, selenium imagwira ntchito yofunika kwambiri pa chitetezo chamthupi, kuyika selenium m'thupi, kutulutsa mahomoni, ntchito ya ma enzymes am'mimba, ndi zina zotero.
