ʻO ka Wikamina A he wikamina hiki ke hoʻoheheʻe ʻia ka momona he mea nui ia no nā hana o ke kino, e like me ka ʻike pono, kahi ʻōnaehana ikaika, hana hou a me ke olakino maikaʻi o ka ʻili.

ʻElua ʻano o ka wikamina A i loaʻa i loko o nā meaʻai: ka wikamina preformed a me ka provitamin A (1).

ʻO ka huaʻai A i hana mua ʻia ʻike ʻia hoʻi me retinol a ʻike pinepine ʻia i kaʻiʻo, iʻa, hua manu a me nā huahana waiū.

Ma ka ʻaoʻao ʻē aʻe, hoʻololi ke kino i nā carotenoids i nā meaʻai mea kanu, e like me ka ʻulaʻula, ʻōmaʻomaʻo, melemele a me nā hua ʻalani a me nā huaʻai, i loko o ka huaora A ().

ʻOiai he kakaikahi ka hemahema ma nā ʻāina kūkulu, ʻaʻole nui ka poʻe ma nā ʻāina kūkulu i lawa ka wikamina A.

ʻO nā mea i makaʻu nui loa i ka hemahema nā wahine hāpai, nā makuahine hānai, nā pēpē a me nā keiki. Hiki i ka cystic fibrosis a me ka diarrhea mau ke hoʻonui i kou makaʻu o ka hemahema.

Eia nā hōʻailona 8 a me nā ʻōuli o ka hemahema o ka wikamina A.

1. Ka ʻili maloʻo

He mea nui ka wikamina A no ka hana a me ka hoʻoponopono ʻana i nā hunaola o ka ʻili. Mālama pū kekahi ia i ka hakakā ma muli o kekahi pilikia o ka ʻili ().

ʻO ka lawa ʻole o ka wikamina A e hewa ai no ka hoʻomohala ʻana o ka eczema a me nā pilikia ʻili ʻē aʻe ().

ʻO ka Eczema kahi ʻano e hoʻomoe i ka ʻili maloʻo, ʻili a ʻā hoʻi. Ua hōʻike ʻia kekahi mau noiʻi hoʻokolohua i ka alitretinoin, kahi lāʻau i kuhikuhi ʻia me ka lāʻau vitamin A, e pono ai i ka mālama ʻana i ka eczema (, 5,).

I hoʻokahi mau hebedoma hebedoma he 12, ʻo ka poʻe me ka eczema maʻi mau i lawe i ka 10-40 mg o alitretinoin i kēlā me kēia lā i ʻike ʻia i kahi 53% hōʻemi o kā lākou mau hōʻailona ().

E hoʻomanaʻo he hiki i ka ʻili maloʻo ke loaʻa i nā kumu he nui, akā ʻo ke kumu ʻole o ka wikamina A mau ke kumu.

He mea nui ka wikamina A i ka hoʻoponopono ʻana o ka ʻili a kōkua i ke kaua ʻana i ka mumū. Hiki i kahi hemahema i kēia mea hānai ke alakaʻi i nā ʻano ʻili hōʻeha.

2. ʻO nā maka maloʻo

ʻO nā pilikia o ka maka kekahi o nā pilikia i ʻike nui ʻia e pili ana i ka hemahema o ka wikamina A.

I nā hihia koʻikoʻi, ʻaʻole lawa ka lawa ʻana o ka wikamina A hiki ke alakaʻi i ka makapō piha a i ʻole ke make ʻana i nā kornea, i ʻike ʻia e nā māka i kapa ʻia nā kiko o Bitot (,).

ʻO nā maka maloʻo, a i ʻole hiki ʻole ke hana i nā waimaka, ʻo ia kekahi o nā hōʻailona mua o ka lawa ʻole o ka wikamina A.

ʻO nā kamaliʻi ʻōpio ma India, ʻApelika a me ʻAkia Hema Hikina i loaʻa ʻole nā ​​papaʻai i nele i ka wikamina A i ka makaʻu ʻana i nā maka maloʻo.

Hiki ke hoʻonui i kēia ʻano me ka hoʻopili ʻana me ka huaola A.

Ua ʻike ʻia hoʻokahi noiʻi ua hoʻoliʻiliʻi ka nui o nā wikamina A i ka nui o nā maka maloʻo e 63% i waena o nā pēpē a me nā keiki i lawe i nā mea hoʻopiha no 16 mau mahina ().

Hiki i ka hemahema Vitamin A ke alakaʻi i nā maka maloʻo, ka makapō a i ʻole ke make ʻana i nā korneas, i ʻike ʻia hoʻi me nā kiko o Bitot. ʻO kekahi o nā hōʻailona mua o ka hemahema ka hiki ʻole ke hana i nā waimaka.

3. Pō makapō

Hiki i ka hemahema wikamina A ke alakaʻi i ka makapō o ka pō ().

Ua hōʻike ʻia kekahi mau noiʻi nānā i ka nui o ka makapō o ka pō i nā lāhui e hoʻomōhala ana (,,).

Ma muli o ka nui o kēia pilikia, ua hana nā ʻoihana olakino e hoʻomaikaʻi i nā pae vitamina A i ka poʻe makaʻu i ka makapō o ka pō.

I hoʻokahi o nā noi ʻana, hāʻawi ʻia nā wahine me ka makapō o ka pō i ka wikamina A i ke ʻano o ka meaʻai a i ʻole nā ​​mea hoʻohui. ʻO nā ʻano ʻelua o ka huaora A i hoʻomaikaʻi i ke ʻano. Ua hoʻonui ka mākaukau o nā wahine e hoʻopili i ka pouli ma mua o 50% ma luna o ʻeono pule o ka mālama ʻana ().

ʻO ka loaʻa ʻana o ka huamini A kūpono no ka olakino maka. ʻO kekahi o nā hōʻailona mua o ka hemahema o ka wikamina A he mau maka maloʻo a me ka makapō o ka pō.

4. Ka hānai ʻana a me nā pilikia e hāpai nei

Pono ka wikamina A no ka hana hou i nā kāne a me nā wahine, a me ka hoʻomohala kūpono ʻana i nā pēpē.

Inā pilikia ʻoe i ka hāpai ʻana, ʻo ka nele o ka wikamina A ke kumu o ke kumu. Hiki i ka hemahema Vitamin A ke alakaʻi i ka infertility i nā kāne a me nā wahine.

Hōʻike nā noiʻi e paʻakikī ka hāpai ʻana o nā ʻiole wahine me ka hemahema o ka huaora A a he mau embryo paha me nā hānau hānau (17).

Hōʻike kekahi mau noiʻi ʻē aʻe e pono i nā kāne infertile i ka pono nui no nā antioxidant ma muli o ke kiʻekiʻe o ke koʻikoʻi oxidative i ko lākou mau kino. ʻO ka wikamina A kekahi o nā meaola e hana ma ke ʻano he antioxidant i ke kino ().

ʻO ka hemahema ʻo Wikamina A pili pū kekahi i nā hāʻule ʻana o ka hāpai keiki.

ʻO kahi noiʻi i kālailai i nā kiʻekiʻe o ke koko o nā meaola like ʻole i nā wahine i loaʻa i nā hāʻule hou ʻole i loaʻa he haʻahaʻa ko lākou mau huaora A ().

Hiki i nā kāne a me nā wahine ʻaʻole i lawa ka wikamina A ke loaʻa nā pilikia momona. Hiki i ka huaora A haʻahaʻa i nā mākua ke alakaʻi i ka hānau hānau ʻole a i ʻole nā ​​hānau hānau.

5. Hoopanee ka ulu ana

ʻO nā keiki i lawa ʻole ka wikamina A hiki ke ʻike i ka ulu ʻana o ka ulu. ʻO kēia no ka pono o ka wikamina A no ka ulu kūpono ʻana o ke kino o ke kanaka.

Ua hōʻike ʻia kekahi mau noiʻi e hiki i ka huaʻai A ke hoʻohui, a i ʻole me nā meaola ʻē aʻe, hiki ke hoʻomaikaʻi i ka ulu ʻana. Ua alakaʻi ʻia ka hapa nui o kēia mau aʻo ʻana i nā keiki i nā lāhui e ulu ana (,,,).

ʻO ka ʻoiaʻiʻo, kahi noiʻi ma luna o nā keiki he 1000 ma Indonesia i ʻike ʻia ʻo ka poʻe me ka lawa ʻole ka wikamina A i lawe i nā mea hoʻoliʻiliʻi kiʻekiʻe ma mua o ʻehā mau mahina i ulu aʻe he 0.15 iniha (0.39 cm) ma mua o nā keiki i lawe i kahi placebo ().

Eia naʻe, ua loaʻa kahi loiloi o nā noiʻi i ka hoʻopili ʻana me ka huaʻai A i ka hui pū ʻana me nā meaola ʻē aʻe i ka hopena nui aʻe i ka ulu ʻana ma mua o ka hoʻopili ʻana me ka huaora A wale nō ().

ʻO kahi laʻana, ʻo nā keiki me ka ulu ulu nui o ʻApelika Hema i loaʻa nā helu he nui a me nā minelala he mau helu lōʻihi-no ka makahiki i hapa hapalua keu ma mua o ka poʻe i loaʻa wale ka lāʻau A ().

Hiki i ka hemahema Vitamin A ke kumu i ka ulu ʻana o nā keiki. Hoʻohui me ka wikamina A i ka hui pū ʻana me nā meaola ʻē aʻe e hoʻomaikaʻi ai i ka ulu ʻana ma mua o ka hoʻopili ʻana me ka wikamina A wale nō.

6. Nā maʻi maʻi puʻu a me ka umauma

ʻO nā maʻi pinepine, keu hoʻi i ka ʻāʻī a i ʻole ka umauma, he hōʻailona paha ia o ka hemahema o ka wikamina A.

Kōkua paha nā mea hoʻohui Vitamin A me nā maʻi maʻi hanu, akā ua huikau nā hopena noiʻi.

Ua hōʻike ʻia kahi noiʻi i nā keiki ma ʻEkuador, ʻo nā kamaliʻi paona ʻole i lawe i ka 10,000 IU o ka huaola A i kēlā me kēia pule, ua ʻoi aku ka liʻiliʻi o nā maʻi hanu ma mua o ka poʻe i loaʻa kahi placebo ().

Ma ka ʻaoʻao ʻē aʻe, kahi loiloi o nā noiʻi i nā keiki i ʻike ʻia e hoʻonui ʻia ka hopena o ka wikamina A i ka hopena o ka ulu ʻana o ka ʻāʻī a me ka umauma e 8% ().

Ua ʻōlelo nā mea kākau e hāʻawi wale ʻia nā mea hoʻopiha i ka poʻe me ka hemahema maoli ().

Eia kekahi, e like me kahi noiʻi i ka poʻe ʻelemākule, hiki i nā pae koko kiʻekiʻe o ka provitamin A carotenoid beta-carotene ke pale aku i nā maʻi hanu ().

Hiki i nā huakino Vitamin A ke pale aku i nā keiki underweight mai nā maʻi akā e hoʻonui i ka hopena o ka maʻi i nā hui ʻē aʻe. Hiki i nā mākua me nā kiʻekiʻe o ke koko kiʻekiʻe o ka wikamina A ke ʻike i ka liʻiliʻi o ka puʻu a me nā maʻi o ka umauma.

7. Ka hoʻōla hōʻeha maikaʻi ʻole

ʻO nā ʻeha e hoʻōla maikaʻi ʻole ma hope o ka hōʻeha a i ʻole ke ʻoki ʻana e hoʻopili ʻia i nā pae vitamona haʻahaʻa.

ʻO kēia no ka mea hoʻolaha ka wikamina A i ka hana ʻana o collagen, kahi mea nui o ka ʻili olakino. Hōʻike ka noiʻi e hiki i nā huaʻōlelo waha a waha paha ke hoʻoikaika i ka ʻili.

Ua loaʻa kahi noiʻi i nāʻiole i ka wikamina waha A hoʻomaikaʻi i ka hana collagen. Ua loaʻa kēia hopena i ka huaora ʻoiai ʻo ka ʻiole e lawe nei i nā steroid, hiki ke pale i ka hōʻeha ʻana o ka ʻeha ().

Ua ʻike ʻia kahi noiʻi hou i nā ʻiole i ka mālama ʻana i ka ʻili me nā huaora A topical i pale ʻia i nā ʻeha e pili ana i ka maʻi diabetes ().

Hōʻike ka noiʻi i nā kānaka i nā hopena like. ʻO nā kāne ʻelemākule nāna i mālama i nā ʻeha me ka lāʻau kumuhana A he 50% hōʻemi o ka nui o ko lākou mau ʻeha, hoʻohālikelike ʻia me nā kāne i hoʻohana ʻole i ka kirimalu ().

Hiki i nā ʻano waha a me nā kumuhana o ka wikamina A ke hoʻolauna i ka hōʻeha ʻana i ka ʻeha, keu hoʻi i nā heluna kanaka i hiki i nā ʻeha.

8. Huehue a me Breakouts

Ma muli o ka hoʻolauna ʻana o ka wikamina A i ka ulu ʻana o ka ʻili a me ka hakakā ʻana i ka mumū, kōkua paha ia i ka pale a mālama ʻana paha i ka huehue.

Ua hoʻopili nā noiʻi he nui i nā pae vitamona haʻahaʻa i ke alo o ka huehue (,).

I hoʻokahi noiʻi i 200 mau mākua, ʻo nā pae vitamine A i ka poʻe me ka huehue ma mua o 80 mcg haʻahaʻa ma mua o nā mea me ke ʻano ʻole ().

Hiki ke mālama ʻia nā huehue i ka kumuhana A a me ka oral A. Hōʻike ka noiʻi e hiki i nā kalima i loko o ka wikamina A ke hoʻemi i ka helu o nā lehelehe huehue e 50% ().

ʻO ka mea kaulana loa o ka huaora waha A i hoʻohana ʻia e mālama ai i ka huehue isotretinoin, a i ʻole Accutane. Hiki ke maikaʻi loa kēia lāʻau i ka mālama ʻana i ka huehue akā loaʻa paha i nā hopena ʻaoʻao, e like me nā loli o ka naʻau a me nā hānau hānau ().

Ua pili ka huehue me nā pae vitamona haʻahaʻa. ʻO nā ʻano ʻelua nā waha a me nā kumuhana o ka wikamina A i ka mālama pinepine ʻana i ka huehue akā loaʻa paha nā hopena ʻaoʻao i makemake ʻole ʻia.

Nā pilikia o ka nui o ka Vitamin A

He mea waiwai ka wikamina A i ke olakino holoʻokoʻa. Eia naʻe, ʻo ka nui loa o ia mea hiki ke weliweli.

ʻO Hypervitaminosis A, a i ʻole ka huakino A ʻona, nā hopena maʻamau mai ka lawe ʻana i nā mea hoʻoliʻiliʻi kiʻekiʻe ma nā manawa lōʻihi. Kākaʻikahi ka poʻe i ka nui o ka wikamina A mai kaʻai wale nō (34).

Mālama ʻia ka nui o ka wikamina A i loko o ke akepaʻa a hiki ke alakaʻi i ka lāʻau ʻona a me nā ʻōuli pilikia, e like me ka loli ʻana o ka hihiʻo, ka pehu ʻana o nā iwi, ka ʻili maloʻo a ʻeleʻele hoʻi, nā puʻupuʻu waha a me nā huikau.

E akahele pono nā wahine hāpai ʻaʻole e ʻai nui i ka wikamina A e pale ai i nā kīnā hānau.

E hōʻoia mau me kāu kauka olakino ma mua o ka hoʻomaka ʻana i nā mea hoʻohui vitamina A.

Pono paha ka poʻe me kekahi ʻano olakino i ka nui o nā huaora A. akā, pono ka hapa nui o nā mākua olakino 700-900 mcg i kēlā me kēia lā. Pono nā wahine hānai e ʻoi aku ka nui, ʻoiai ʻo ka liʻiliʻi o nā keiki (1).

ʻO ka hopena ʻo Vitamin A ka hopena ma muli o ka lawe ʻana i ka nui o ka wikamina i loko o ka form supplement. Hiki iā ia ke kumu i nā pilikia koʻikoʻi, e pili ana i nā loli o ka hihiʻo, nā puʻupuʻu waha, nā huikau a me nā kīnā hānau.

Ka Laina Lalo

Kūleʻa ka hemahema o ka wikamina A i nā lāhui e ulu ana akā ʻaʻole ʻike ʻia ma ʻAmelika a me nā lāhui ʻē aʻe i ulu.

Hiki i ka liʻiliʻi o ka wikamina A ke alakaʻi i ka ʻili i hoʻā ʻia, makapō o ka pō, infertility, hoʻolohi a me nā maʻi hanu.

ʻO ka poʻe me nā ʻeha a me ka huehue e loaʻa i nā pae koko haʻahaʻa o ka wikamina A a pōmaikaʻi i ka mālama ʻana me nā ʻoi kiʻekiʻe o ka vitamina.

Loaʻa ka wikamina A i ka ʻiʻo, ka waiū a me nā hua manu, a me ka mea ʻulaʻula, ʻalani, melemele a me nā mea kanu ʻōmaʻomaʻo. I mea e lawa pono ai ka wikamina A, ʻai i nā ʻano meaʻai like ʻole.

Inā manaʻo ʻoe he hemahema ka huaora A, e kamaʻilio me kāu kauka a mea lawelawe olakino. Me nā meaʻai kūpono a me nā mea hoʻopiha, hiki ke maʻalahi i ka hoʻoponopono ʻana i kahi hemahema.
