Inā ponoʻoe e loaʻa nā kākoʻo DV vitamins, hiki iāʻoe keʻike iʻelua koho ma nā papa: D2 a me D3. ʻO kēia nāʻanoʻelua o keʻano o ka huaʻaina D. Inā makemake wau eʻohi i kahi kōlamu D, hiki iaʻu ke leʻaleʻa i D3, akāʻaʻole paha he mea nui-ma hope o nā mea a pau, ua hoʻohanaʻiaʻo D2 no nā makahiki he nui.
ʻO kaʻene Vitamin D e like me ka hormone e kōkua ai i kou kino e hoʻomoho a hoʻohana i ka calcium a hoʻoponopono i ka nui o ka calcium i loko o kou koko.
Ināʻaʻoleʻoe i lawa ka nui o ka vitamona D, e hoʻomāhuahuaʻoe i ka pilikia o ka osteoporosis a iʻole nā maʻi maʻi'ē aʻe e like me ka osteomalacia a me ka osteopenia. Pono nō hoʻi ka Vitamin D no ka pūnaehana olakino olakino a me ka noʻonoʻo maʻamau a me ka hana ma'ū.
ʻO kahi mea liʻiliʻi o Vitamin D Biochemistry
ʻO Cholecalciferol (ʻo iaʻo D3) keʻano o ka huaʻaina D i loaʻa i nā holoholona. Keʻikeʻia kouʻili i nā kukuna UVB o ka lā, e hoʻololi ke kino i kahi mea i kapaʻiaʻo 7-Dehydrocholesterol ma o ka pae hana kumuhana biochemical to cholecalciferol. A laila ma kekahiʻano hou, ua hoʻololiʻia ka cholecalciferol i ka calcifediol, aʻo ia hoʻi ka 25-hydroxyvitamin D3 aʻo ia keʻano e hanaʻia ai ka mīkini i ka manawa e kauoha ai kāu kauka i ka hōʻoia vitamin D.
ʻO ka hopena, hoʻololiʻia kou kino i ka manaʻoi o ka lāʻau D (ka mea hana i ka hana) i kapaʻia he calcitriol.
Kūkulu nā kanu i keʻano like, akā, ma kahi o ka cholecalciferol, ua laweʻia nā ergocalciferol (D2).
ʻO nā koho a Cholecalciferol a me ergocalciferol e like me keʻano maʻamau a me ka hopena o nā makahiki 1920, uaʻikeʻia ua hoʻohanaʻia ka ergocalciferol no ka hanaʻana i nā mea hōʻoki i nā keiki. No nā makahiki he nui, ua'āponoʻia ka ergocalciferol e like me keʻano o ka huaʻi D.
I ka makahiki 1980 a me ka 90, ua'ōlelo ka poʻeʻepekema e like me keʻano o ka holoholona holoholona, D3, heʻoi aku ka maikaʻi i ka hoʻonuiʻana i nā kūlana o ka waiʻona D3 (25-hydroxyvitamin D3).
Mai laila maiʻelua mauʻimi noiʻi iʻikeʻole heʻano likeʻole ma waena o nāʻaoʻaoʻelua aʻo kaʻekolu ke piʻi wikiwiki houʻia me nā hoʻopiʻi D3, akā,ʻaʻole i maopopo nā mea noiʻi inā he nui keʻano o ka hoʻokele.
No ke aha i loaʻa ai nā hopena likeʻole o nā haʻawina? Hiki i nā kumu he nui ke hoʻoholo i nā noiʻi noiʻi no kēiaʻano. Ua hanaʻia kahi hoʻokahi ma ka makahiki kauwela i hiki i kaʻikeʻana o ka lā ke hoʻopuka i nā hualoaʻa. A o ka meaʻai a me ka hoʻohanaʻana i nā meaʻai meaʻai e hiki ke hoʻololi i nā mea. ʻO wai ka poʻe maikaʻi loa e aʻo? ʻO nā maʻi me ka osteoporosis? ʻO ka maʻi hōkiʻi? ʻO nā kānaka olakino, hiki paha iā lākou ke emi iki i ka meaʻai D? ʻO nāʻelemakule? Ōpio kānaka? Mai nā kāne? Nā wāhine? Hiki ke paʻakikī ka noiʻi no ka mea hoʻokahi like nā mea i loaʻa no ka hui hoʻokahi.
Hoʻomaopopo wau eʻoi aʻe ana ka noiʻiʻana i nā mea likeʻole ma waena o D2 a me D3. Akā i kēia manawa, inā e hopohopoʻoe e pili ana i kāu mau māmona D ,ʻo ka mea maikaʻi loa e hanaʻia, e hele i kahi kahu mālama ola e nānā i ka nui o kāu mauʻano koko o ka huaʻo D. Inā lākou heʻuʻuku, hiki iāʻoe ke lawe i keʻano o ka huaʻaola D a ma hope o nā pule hebedoma, e nānā hou i kou koko eʻike ai inā e hana ana nā mea hoʻopiha.
E hahai mau i nā kuhikuhi o ka lepili no ka laweʻana i nā meaʻai DV D a koe ke hōʻikeʻole iāʻoe i kāuʻike mālama ola.
