Hoʻonui i ka palekana
Hiki i ka selenium hana kanu ke hoʻomaʻemaʻe i nā radical manuahi i loko o ke kino, hoʻopau i nā toxins i loko o ke kino, antioxidant, hiki ke pale pono i ka hana ʻana o ka lipid peroxide, pale i nā clots koko, wehe i ka cholesterol, a hoʻonui i ka hana pale kanaka.
Kāohi i ka maʻi diabetes
ʻO Selenium ka mea ikaika o ka glutathione peroxidase, hiki ke pale i ka luku oxidative o nā pūnae beta islet, hana i ka hana maʻamau, hoʻoikaika i ka metabolism sugar, hoʻemi i ke kō koko a me ka mimi kō, a hoʻomaikaʻi i nā hōʻailona o nā maʻi maʻi diabetes.
Kāohi i ka cataract
Hiki ke hoʻopōʻino ʻia ka retina ma muli o ka ʻike nui ʻana i ka radiation kamepiula, hiki i ka selenium ke pale i ka retina, hoʻomaikaʻi i ka pau ʻana o ke kino vitreous, hoʻomaikaʻi i ka ʻike maka, a pale i ka cataracts.
