Ingaba isebenza kanjani?

I-Selenium isebenza kakhulu njenge-antioxidant. Inceda ekunciphiseni ii-free radicals - iimolekyuli ezingazinzanga ezinokubangela umonakalo kwiiseli. Ngokwenza njalo, i-selenium ikhusela iiseli kwi-oxidative stress, enxulunyaniswa nezifo ezahlukeneyo ezingapheliyo, kubandakanya umhlaza kunye nesifo sentliziyo. Ukongeza, i-selenium yinxalenye yee-enzymes ezininzi ezibalulekileyo, ezifana ne-glutathione peroxidase, enceda ekucoceni izinto ezinobungozi emzimbeni.

Isisombululo kunye noLawulo

Umlinganiselo oqhelekileyo we-selenium uyahluka ngokuxhomekeke kubudala, isini, kunye nesimo sempilo. Kwabantu abadala, isibonelelo sokutya esicetyiswayo (RDA) yi-55 mcg/ngosuku. Qaphela: I-EU/EFSA isebenzisa i-70 mcg/ngosuku; chaza umthombo ukuba ummandla othile (umz., eIndiya, i-ICMR ihambelana kufutshane ne-40 mcg/ngosuku).

Kubantwana, idosi yile ilandelayo:

• Iintsana (iinyanga ezi-0-6): 15 mcg (ukutya okwaneleyo)
• Abantwana (iinyanga ezi-7 ukuya kwezi-12): 20 mcg
• Abantwana (iminyaka emi-1 ukuya kweyesi-3): 20 mcg
• Abantwana (iminyaka emi-4 ukuya kweyesi-8): 30 mcg
• Abantwana (abaneminyaka eyi-9-13): 40 mcg (amantombazana), 55 mcg (abafana, ngokufuthi ngokwesilinganiso)
• Ulutsha (iminyaka eli-14-18): 55 mcg

ISelenium inokulawulwa ngeendlela ezahlukeneyo, kuquka iipilisi, iipilisi, iinaliti. Kubalulekile ukulandela iingcebiso zomboneleli wezempilo malunga nedosi kunye nolawulo.
