ʻO ka Vitamin A - nā kumu, nā hopena i ke kino, nā hopena o ka hemahema a me ka overdose

Maikaʻi i hōʻoia ʻia

ʻO ka Vitamin A ka inoa maʻamau no nā pūhui organik mai ka hui o retinoids. Hoʻomaopopo pinepineʻiaʻo ia he Retinol, beta-carotene, axophthol a me provitamin A. Aia ia i ka hui o nā huaora momona. I nā mea kanu, hōʻiliʻili kēia hui i ke ʻano o nā carotenoids. I loko o ke kino, mālama ʻia ka huaora A ma ke ʻano he Retinol i loko o ke ake a me ka ʻiʻo adipose. ʻO ia kekahi o nā huaora i ʻike mua ʻia ma ka mōʻaukala o ka lāʻau lapaʻau. Ma mua, ma mua o ka loaʻa ʻana o ka vitamina A, ua mālama ʻia nā hopena o kona hemahema e ka poʻe ʻAigupita kahiko, Helene a me Roma. Ua kapa ʻia ka maʻi he makapō pō a i ʻole makapō pō a ʻo ka mālama ʻia ʻana o ka ʻai ʻana i ke ake o nā holoholona maka a i kuke ʻia paha.

ʻO ke kuleana o ka vitamina A i ke kino

ʻO ka Vitamin A he huaʻai koʻikoʻi nui ia no ka hana o ko mākou kino. He mea nui ia i ke kaʻina hana o ka hihiʻo, hoʻololi i ka ulu ʻana, a hoʻoponopono i ka ulu ʻana o ka ʻiʻo epithelial a me nā mea ʻē aʻe o ke kino. Eia kekahi, loaʻa iā ia nā waiwai anti-cancer, pale i ka epithelium o ka ʻōnaehana hanu e kūʻē i nā microorganism, hoʻoikaika i ka ʻōnaehana pale, pale i nā maʻi, kōkua i ka hakakā ʻana i ka bacteria a me nā maʻi virus, mālama i ke kūlana kūpono o ka ʻili, ka lauoho a me nā kui, a pili pū i ka ka hana kūpono o nā membrane cell. Hoʻoulu hou ka Vitamin A i ka ʻili maloʻo, no laila pono e hoʻohana i nā mea hoʻonaninani me kāna hoʻohui, e like me ka revitalizing Vianek hoʻomaʻemaʻe gel no ka ʻili makua a paʻakikī.

He meaʻai koʻikoʻi ka Vitamin A e hoʻopōmaikaʻi i kou olakino ma nā ʻano he nui.

ʻO ka Vitamin A he antioxidant ikaika

ʻO nā carotenoids Provitamin A e like me ka beta-carotene, alpha-carotene a me ka beta-cryptoxanthin he mau mua ia i ka huaʻa A a loaʻa nā waiwai antioxidant.

Wahi a nā hopena o kahi noiʻi i paʻi ʻia ma Pharmacognosy Reviews i ka makahiki 2010, hakakā nā carotenoids i nā radical manuahi - nā molekole reactive hiki ke hōʻeha i ko mākou kino ma o ka hoʻoulu ʻana i ke koʻikoʻi oxidative. Hoʻopili ʻia ke koʻikoʻi Oxidative i nā maʻi maʻi like ʻole e like me ka maʻi maʻi, ka maʻi kanesa, ka maʻi puʻuwai, a me ka emi ʻana o ka cognitive, i hōʻoia ʻia e nā haʻawina e like me nā mea i paʻi ʻia ma Oxidative Medicine a me Cellular Longevity i 2017.

ʻO nā meaʻai kiʻekiʻe i nā carotenoids e pili ana me ka haʻahaʻa haʻahaʻa no ka nui o kēia mau maʻi, e like me ka maʻi maʻi puʻuwai, ka maʻi kanesa a me ka maʻi diabetes.

Pono ka Vitamin A no ka mālama ʻana i ka ʻike maka. Pono ka Vitamin A no ka hoʻololi ʻana i ka mālamalama i hiki i ka maka i hōʻailona uila e hiki ke hoʻouna ʻia i ka lolo. ʻO ka ʻoiaʻiʻo, ʻo kekahi o nā hōʻailona mua o ka hemahema o ka huaora A he makapō pō, i kapa ʻia ʻo ka pō pō.

Loaʻa ka makapō pō i ka poʻe i nele i ka vitamina A, no ka mea, ʻo kēia vitamina ka mea nui o ka pigment rhodopsin. Loaʻa ka Rhodopsin i loko o ka retina o ka maka a he māmā loa. ʻIke maʻamau ka poʻe me kēia maʻi i ka lā, akā ua liʻiliʻi ka ʻike i ka pōʻeleʻele no ka mea paʻakikī ko lākou mau maka i ka ʻohi ʻana i ka mālamalama ma nā pae haʻahaʻa.

E like me ka mea i hōʻoia ʻia e kahi noiʻi 2015 i paʻi ʻia ma JAMA Ophthalmology, ma waho aʻe o ka pale ʻana i ka makapō pō, ʻo ka ʻai ʻana i ka nui o ka beta-carotene hiki ke kōkua i ka hōʻemi ʻana i ka pōʻino o ka maka i ʻike ʻia e kekahi poʻe me ka makahiki.

ʻO ka macular degeneration pili makahiki (AMD) ke kumu nui o ka makapō ma nā ʻāina kūkulu. ʻOiai ʻaʻole ʻike ʻia kona kumu maoli, ua manaʻo ʻia ʻo ia ka hopena o ka pōʻino cellular i ka retina, i pili i ke koʻikoʻi oxidative (e like me ka mea i hōʻoia ʻia ma kahi noiʻi 2000 ma ka Survey of Ophthalmology).

Eia nō naʻe, ua ʻike ʻia kahi loiloi Cochrane hou ʻaʻole nā ​​​​mea hoʻohui beta-carotene wale nō e pale a hoʻopaneʻe paha i ka pōʻino ʻike i hana ʻia e AMD.

Hoʻomaka ka maʻi maʻi i ka wā e hoʻomaka ai ka ulu ʻana a i ʻole ka puʻunaue ʻana o nā cell abnormal.

No ka mea he mea koʻikoʻi ka huaora A i ka ulu ʻana a me ka hoʻomohala ʻana o nā cell, ʻo kona hopena i ka pilikia o ka maʻi maʻi a me ka hana i ka pale ʻana i ka maʻi kanesa he mea hoihoi ia i nā mea noiʻi.

Ma nā haʻawina nānā (e like me ka mea i paʻi ʻia ma ka Annals of Hematology ma 2017 a i ʻole Gynecologic Oncology ma 2012), ʻo ka ʻai ʻana i ka nui o ka nui o ka huaora A ma ke ʻano o ka beta-carotene ua pili pū me ka hōʻemi ʻana o kekahi mau ʻano maʻi kanesa, me ka lymphoma o Hodgkin, a ʻo ka maʻi ʻaʻai ʻana o ka ʻōpū, ka māmā a me ka ʻōpū.

Eia naʻe, ʻoiai e pili ana ka lawe nui ʻana i ka huaora A mai nā meaʻai mea kanu me ka hōʻemi ʻana o ka maʻi kanesa, ʻaʻole pili like nā meaʻai holoholona i loaʻa i nā ʻano ikaika o ka vitamina A (kahi noiʻi 2015 i paʻi ʻia ma ka Archives of Biochemistry and Biophysics).

Pēlā nō, e like me ka noiʻi 1999 i paʻi ʻia ma ka Journal of the National Cancer Institute, ʻaʻole i hōʻike nā mea hoʻohui huaʻai A i nā hopena maikaʻi like.

I kēia manawa, ʻaʻole maopopo loa ka pilina ma waena o nā pae vitamina A i loko o ko mākou kino a me ka maʻi kanesa. Eia nō naʻe, e like me ka noiʻi 2015 i paʻi ʻia ma BioMed Research International, loaʻa ka loaʻa ʻana o ka vitamina A kūpono, ʻoi aku ka nui o nā mea kanu, he mea nui ia no ka mahele cell olakino a hiki ke hōʻemi i ka pilikia o kekahi mau ʻano maʻi kanesa.

E nānā i kekahi: He lāʻau e hōʻemi i ka pilikia o ka ulu ʻana i ka maʻi maʻi umauma. Ke hoʻomau nei ka noiʻi

ʻO ka Vitamin A e hoʻemi i ka pilikia o ka haki

He ma'i ma'i ma'i ma'i ka 'ili. ʻO ka poʻe me kēia maʻi e ulu ana i nā pimples ʻeha a me nā ʻeleʻele, ʻoi pinepine ma ka maka, ke kua, a me ka umauma.

ʻOiai ʻaʻohe pōʻino kino o nā pimples, hiki i ka ʻekene ke loaʻa i ka hopena koʻikoʻi i ke olakino noʻonoʻo o nā kānaka a alakaʻi i ka haʻahaʻa haʻahaʻa, hopohopo a me ke kaumaha (e like me ka hoʻopaʻa ʻana i ka makahiki 2016 i paʻi ʻia ma Clinical, Cosmetic and Investigational Dermatology). ʻAʻole maopopo ka hana pololei a ka vitamina A i ka hoʻomohala ʻana a me ka mālama ʻana i ka haki.

ʻO kahi haʻawina e like me ka mea i paʻi ʻia ma ka 2015 Journal of Nutrition & Food Science ua manaʻo e hiki i ka nele o ka huaora A ke hoʻonui i ka pilikia o ka hoʻomohala ʻana i ka ʻekene no ka mea e hoʻonui ai i ka protein keratin i loko o nā follicles lauoho. ʻO kēia ka mea e hoʻonui ai i ka pilikia o ka ʻeʻe ma o ka paʻakikī ʻana i ka wehe ʻana i nā ʻili make mai nā follicles lauoho, e alakaʻi ana i ka paʻa ʻana o ka ʻili.

E nānā i kekahi: Pehea e wehe ai i ka ʻekene?

Pono ka Vitamin A no ka ulu ʻana a me ka ulu ʻana o ka pēpē

He mea nui ka Vitamin A no ka mālama ʻana i kahi ʻōnaehana hānau maikaʻi i nā kāne a me nā wahine, a no ka ulu kūpono a me ka ulu ʻana o nā embryos i ka wā hāpai.

ʻO kahi haʻawina i nā ʻiole i paʻi ʻia ma Nutrients i ka makahiki 2011 e pili ana i ke koʻikoʻi o ka huaora A i ka hoʻohua kāne kāne i ʻike ʻia ʻo ka hemahema e pale ai i ka ulu ʻana o ka sperm, e hoʻoulu ai i ka infertility. ʻO ka haʻawina hoʻokahi i ʻōlelo ʻia e hōʻike ana i ka hemahema o ka huaʻa A i nā wahine e hoʻopilikia i ka hānau ʻana ma o ka hoʻohaʻahaʻa ʻana i ka maikaʻi o ka hua a me ka hoʻopili ʻana i ka implantation o ka hua i loko o ka ʻōpū.

Kākoʻo ka Vitamin A i ke olakino o ka ʻōnaehana pale ma o ka hoʻoulu ʻana i nā pane e pale i ke kino mai ka maʻi a me ka maʻi. Hoʻokomo ʻia ka Vitamin A i ka hoʻokumu ʻana i kekahi mau sela, me nā lymphocytes B a me T, kahi mea nui i ka pane ʻana i ka pale ʻana i ka maʻi.

E like me ka mea i hōʻoia ʻia ma kahi noiʻi 2012 i ka Proceedings of the Nutrition Society, ʻo ka hemahema o kēia meaʻai e alakaʻi i ka piʻi ʻana o nā molekole pro-inflammatory e hoʻonāwaliwali i ka pane a me ka hana ʻana o ka ʻōnaehana pale.

Kākoʻo ka Vitamin A i ke olakino iwi

ʻO nā meaʻai nui e pono ai no ka mālama ʻana i nā iwi olakino e like me kou mau makahiki, ʻo ia ka protein, calcium, a me ka huaora D. Eia nō naʻe, ʻo ka ʻai ʻana i ka nui o ka huaora A he mea nui nō hoʻi no ka ulu ʻana a me ka ulu ʻana o ka iwi, a ua pili ka hemahema o kēia huaora i ke olakino iwi maikaʻi ʻole.

Wahi a kahi noiʻi 2017 i paʻi ʻia ma ka International Journal of Environmental Research and Public Health, ʻoi aku ka nui o nā poʻe me nā pae koko haʻahaʻa o ka huaora A e hoʻomohala i nā haʻihaʻi iwi ma mua o ka poʻe me nā pae olakino.

E nānā i kekahi: ʻAi ma hope o ka haki ʻana o ka iwi

ʻO ka loaʻa ʻana o ka vitamina A.

Hiki ke loaʻa ka Vitamin A, ma waena o nā mea ʻē aʻe, i ka pata, ka waiū a me nā huahana waiu, kekahi iʻa momona, ate a me nā ʻāpana holoholona, ​​​​huamoa, ʻuala, kale, spinach a me ka paukena. ʻO nā carotenoids i makemake nui ʻia, ma waena o ka beta carotene ka mea nui loa, aia i loko o ka spinach, kāloti, nā tōmato, ka ʻulaʻula a me ka letus. ʻO nā huaʻai i waiwai nui i nā carotenoids, no ka laʻana, cherries, apricots, peaches a me plums. ʻO ka huahana i hoʻohana pinepine ʻia no ka hoʻohui ʻana a loaʻa ka nui o ka huaora A ʻo ia ka ʻaila iʻa.
